Explosion-proof electrical appliances are mainly explosion-proof electric air-conditioning, explosion-proof switch electrical appliances, explosion-proof distribution boxes, explosion-proof instruments, explosion-proof complete sets of equipment and electrical accessories.

With the extensive installation of explosion-proof electrical equipment for hazardous materials explosion hazardous locations, the relevant knowledge should also follow up. Explosion-proof electrical appliances are mainly explosion-proof electric air-conditioning, explosion-proof switch electrical appliances, explosion-proof distribution boxes, explosion-proof instruments, explosion-proof complete sets of equipment and electrical accessories. During the use of these devices, due to mechanical wear or material aging, or affected by the use of the environment, or due to equipment inspection, maintenance, repair work errors and other reasons, so that the explosion-proof electrical equipment explosion performance is reduced or even lost, it will cause the formation of ignition sources Explosion or fire accident. Therefore, in the inspection, maintenance and repair work of explosion-proof electrical equipment, how to evaluate the safety and usability of the old explosion-proof electrical equipment is an urgent problem to be solved.
Operational and environmental conditions affect the safety of in-use explosion-proof electrical equipment

Parts 1, 2, 3, 4, 5, 6, 7, 8 and 9 of CB3836 “Electrical Equipment for Explosive Gas Environments”, for the structure, design, manufacture and inspection of explosion-proof electrical equipment of different explosion-proof types Specific regulations. The explosion-proof products manufactured by the manufacturer must meet the requirements of the standard, and must be subjected to explosion-proof inspections by a nationally authorized explosion-proof inspection agency, and production and sales must be allowed after obtaining the explosion-proof certification. The bulk explosion-proof products manufactured by the manufacturer must pass the specified factory inspection and be allowed to leave the factory after passing the inspection. Therefore, in general, the explosion-proof safety performance of new explosion-proof electrical products fully meets the requirements of the standards. However, explosion-proof air conditioning products are affected by working conditions and environmental conditions during use, and are subject to varying degrees of wear and tear. Some damages have an adverse effect on the performance of explosion-proof air-conditioning products; some damage will also reduce the explosion-proof electrical products. Explosion-proof safety. For example, the switch electrical component contacts installed in an explosion-proof flameproof distribution box will have poor contact due to mechanical wear, electrical corrosion, or chemical corrosion, which will affect the use performance of the distribution box; The joint surface is corroded for a long time and rust occurs, so that the flameproof performance is reduced or even lost.

The adverse effects of operating conditions and environmental conditions on explosion-proof electrical equipment are:

Poor operating conditions

Explosion-proof electrical equipment is subjected to strong vibration or impact during operation, which can affect the mechanical structure and strength of small electrical equipment, and can also cause loose electrical connections. Frequent start-up, reverse braking, and overload of the motor will affect the winding temperature of the motor. And the surface temperature affects the safety and service life of the equipment. Increased safety electrical equipment is susceptible to adverse operating conditions.

Wet environment

Explosion-proof electrical equipment is operated or stored in a humid environment for a long period of time, which will affect the insulation of electrical equipment, making it easy for electrical equipment to reduce the insulation resistance, cause electrical breakdown or leakage, and destroy the explosion-proof safety of increased safety type and non-spark type equipment. ***uality can also adversely affect the operational safety of flameproof or other explosion-proof electrical installations. In addition, moisture in the environment will cause flameproof welding of the flameproof equipment and cause corrosion, which will have an adverse effect on the safety of explosion protection.

Corrosion environment

The corrosive environment has a great influence on the explosion-proof electrical equipment. Severe corrosion will cause corrosion of the electrical equipment housing and the fasteners and flameproof joints, destroy the flameproof security of the flameproof housing, and also make other explosion-proof electrical The degree of protection of the device housing is reduced. In addition, corrosive environments can also have an adverse effect on the insulation of electrical equipment, and can also erode exposed conductors, making them poorly contacted and creating sparks.

Ambient temperature

Ambient temperature in excess of 40°C will affect the winding temperature and surface temperature of electrical equipment, because normally the allowable ambient temperature range of explosion-proof electrical equipment is -20°C to +40°C, and the ambient temperature exceeds +40°C, which will cause the temperature of electrical equipment. Raise, affect explosion-proof safety. In addition, long-term operation of electrical equipment at high temperatures can affect the life of electrical insulation materials. If the electrical equipment has a plastic housing, high temperatures will accelerate the aging of the plastic, affecting the operational safety and explosion-proof safety of the equipment.

Other adverse conditions

Sunlight, rain, snow, dust, lightning and other conditions will have adverse effects on explosion-proof electrical equipment. Sunlight can accelerate the photo-aging of insulating materials and plastic shells; rain, snow, and dust can reduce the leakage resistance of the insulating parts, and the dust can also affect the lubrication between relative moving parts (for example, bearings) of the equipment and cause friction. High temperature; Lightning produces an inductive surge voltage on the grid, causing damage to the insulation of electrical equipment. Safety Inspection of Explosion-Proof Electrical Equipment In order to ensure explosion-proof safety and operational safety of explosion-proof electrical equipment, regular and daily inspections and maintenance of in-use explosion-proof electrical equipment and electrical installations should be performed. "Electrical Safety Regulations for Explosive Hazardous Locations" (Trial) and IEC60079-17:2002 "Electrical Equipment for Explosive Gas Environments Part 17: Inspection and Maintenance of Electrical Installations in Hazardous Locations (Excluding Coal Mines)" Operation of Explosion-Proof Electrical Equipment and Electrical Installations And maintenance has been specified in terms of explosion-proof safety.

The inspection level is divided into the following methods and contents:

Visual inspection - the inspection of the apparent defect with the naked eye without the use of inspection equipment or tools, ie routine inspections.

Careful inspection - including visual inspection and inspection using inspection equipment. For example, using a stepladder (necessary place) and/or tool can identify a significant defect inspection. This type of inspection is a professional inspection and should generally be conducted on a regular basis.

One-by-one inspections - including careful inspections and inspections where the apparent defect can only be identified by opening the housing and/or (if necessary) using tools and testing equipment. This inspection is an inspection during the overhaul of equipment.

The inspection type is divided according to the inspection implementation time:

Initial inspection—checks of all electrical equipment, systems, and devices before they are put into operation. It is generally performed in conjunction with the installation acceptance of engineering projects or equipment.

Regular inspections - Routine inspections of all electrical equipment, systems, and devices. Can be carefully checked or checked item by item. Regular inspections are divided into professional inspections and overhaul inspections according to the purpose and contents of inspections. Sampling inspections of some electrical equipment, systems, and devices. The sampling inspection may be a visual inspection, a careful inspection or an item-by-item inspection. The specifications and composition of all sampling samples shall be determined according to the purpose of the inspection. The effects of environmental conditions, vibrations, and inherent defects in the design can be monitored through sampling inspections.

Continuous supervision - Regular maintenance, inspection, maintenance, monitoring and maintenance of electrical equipment by experienced and skilled technicians to keep the explosion-proof performance of the equipment in good condition. According to the characteristics of explosion-proof electrical equipment, reference is made to the inspection item list in IEC 60079-17. The inspection items related to the explosion-proof structure and explosion-proof safety of the explosion-proof, increased-safety, and non-sparking electrical equipment related to the equipment itself are listed in Table 1.

Safety evaluation of explosion-proof electrical equipment

The purpose of inspection of explosion-proof electrical equipment is to evaluate the current status of the equipment, to maintain the equipment in a normal state, and to repair or replace equipment that has failed. On the other hand, through daily inspections or professional inspections, it is possible to detect the precursors of equipment failures through the changes in equipment operating status and take relevant measures in a timely manner to avoid the losses caused by equipment failures. In order to evaluate the results of the examination, the basis for evaluation and judgment should be clearly defined. In order to correctly evaluate the safety of the explosion-proof electrical equipment in use, it is necessary to understand the safety level of the new explosion-proof electrical equipment.

New explosion-proof electrical equipment safety

According to the conditions of combustion and explosion, the three elements of flammable substances (for example, natural gas, gasoline vapor, etc.), oxidants (for example, oxygen in air), and ignition sources (open flame, arc, spark, or high temperature) are only in time and space at the same time. When they meet, it is possible to explode or burn. The installation and use of explosion-proof electrical equipment in explosion hazardous environments aims to prevent electrical equipment from becoming a source of ignition. Explosion-proof electrical equipment in accordance with explosion-proof measures are divided into intrinsically safe explosion-proof type, increased safety and other different types. Taking the explosion-proof type as an example, it is to make a sturdy enclosure for electrical equipment, able to withstand the explosion pressure caused by the explosion inside the enclosure without damage; the gap of all joints of the enclosure is less than the maximum experimental safety clearance of the corresponding flammable gas, if flammable When the gas enters the housing and is ignited by the spark, the explosion flame is confined within the housing and cannot ignite the explosive mixture in the external environment of the housing, thereby ensuring the safety of the environment. The shell is a flameproof shell, and the electrical equipment with a flameproof shell is a flameproof electrical equipment.

Explosion-proof electrical equipment is installed and installed in a dangerous explosion environment. Its explosion-proof safety is directly related to production safety. Therefore, safety assessment of explosion-proof electrical equipment in use in the environment should strictly comply with relevant standards and regulations. In the assessment of specific equipment, it is necessary to consider not only the condition of the equipment itself, but also the conditions of the environment, such as the division of hazardous locations and other conditions of the environment, to achieve safety and economy under the premise of safety. Unite.

It is of great significance to improve the quality of the monitoring system and ensure the stable operation of the system by taking appropriate measures to solve problems in response to different fault conditions. Here are some of the personal engineering experience to talk about the common fault points of the video surveillance system and the experience of troubleshooting.

1. Because the connection between the equipment of the security monitoring system involves many lines, if the handling is not good, especially if the line connected to the main equipment is connected improperly or the connection is incorrect, there will be open circuit, short circuit, poor insulation between lines, and misconnection. Problems such as degraded or even degraded equipment performance. In this case, cool analysis and troubleshooting should be performed according to the fault phenomenon to determine what kind of fault phenomenon may occur when there is a problem with the line connection. In addition, it should be noted that the connections between the various system devices and the various lines should meet the requirements for long-term operation of the monitoring system.

2. The mismatch of the characteristic impedance of the transmission cable may cause some vertical bars with equal spacing on the monitor screen, and the frequency of the interference signal is basically an integral multiple of the line frequency. This interference phenomenon is caused by the fact that the characteristic impedance and distribution parameters of the video cable do not meet the requirements. For such interference, the impedance of each device in the system should be matched as much as possible. Especially when the video cable is purchased, the cable quality must be ensured. If necessary, the cable should be sampled and tested.

3, the communication interface or communication protocol and other parameters are not set well, this situation often occurs between the control host and decoder or control keyboard and other devices with communication control relationship. In other words, the selected control host and decoder or control keyboard, etc., are not set during the installation of the communication protocol and other parameters, so the host, decoder, control keyboard, etc. should pay attention to the communication protocol and other parameters during installation Settings.

4. Common faults of video interference.

• A black bar or white bar appears on the monitor screen and scrolls up or down, which is the so-called 50 Hz power frequency interference. This kind of interference is caused by the potential difference loop caused by the improper grounding of the two devices at the front end and the control center. It may also be caused by the degradation of the power supply performance of the device itself.

The image has snowflake noise. This kind of interference is mainly caused by signal attenuation on the transmission line and coupling of high-frequency interference;

The video image has ghosting, or the image is whitish, the character is dithered, or a number of equally spaced vertical bars interfere on the monitor screen. This is because the characteristic impedance between the video transmission line or the equipment is not 75Ω, resulting in impedance mismatch;

Twill interference, jitter, power interference. When this interference is slight, it does not overwhelm the normal image, but when it is severe, the image is distorted and cannot be viewed. The reasons for this are more and more complicated. For example, the quality of the video transmission line is not good, especially the shielding performance is poor, or the power supply system has clutter, or there may be a strong interference source near the system.

Large area moire interference, also known as single-frequency interference. This phenomenon is mainly caused by the short circuit caused by the short-circuit of the video cable's core wire and the shield, or the failure caused by the open circuit, or due to the bad contact of the BNC connector.

5, equipment failure caused by power problems, there are the following possibilities:

Incorrect supply line or supply voltage;

The power is not enough (or the line of a certain power supply line is enough, the pressure is too large, etc.);

Short circuit, open circuit, instantaneous overvoltage, etc. occur in the transmission lines of the power supply system.

Power supply interference and stability, etc. Power supply interference and transmission stability It should be noted that power supply errors or instantaneous overvoltages can cause equipment damage. Therefore, before the supply of electricity, it must be carefully and strictly checked and checked. It must not be taken lightly.

6, due to the video cable's core and shielding network short circuit, open circuit caused by the failure. This kind of failure manifests itself in a deep and chaotic large-area moire on the monitor, so that the image is completely destroyed and images and synchronization signals cannot be formed. This happens mostly on BNC connectors or other types of video connectors. That is, when such a fault occurs, it is not always a problem in the entire signal line, but merely in the number of unfavorable connections. As long as these joints are carefully checked one by one, it can be solved.

7. Space radiation interference introduced by the transmission line. The reason for this interference phenomenon is that there are strong and high-frequency space radiation sources near the transmission system, the system front-end, or the central control room. The first solution to this situation is to build a system, to achieve a comprehensive understanding of the surrounding environment, and then try to avoid or stay away from radiation sources; Second, when the radiation source can not be avoided, the front-end and center equipment to strengthen the shielding, The pipeline of the transmission line adopts steel pipe and is well grounded.

8. The pan/tilt's faulty pan/tilt common faults often do not work well in use or cannot be turned at all. In addition to product quality reasons, this situation is generally caused by the following reasons:

PTZs that only allow the camera to be mounted are lifted when used. The hoisting method leads to an increase in the operating load of the PTZ. Therefore, the use of the hoisting method will soon lead to damage to the drive mechanism of the PTZ, and even burn the motor.

The total weight of the camera and its protective cover exceeds the weight of the PTZ. Especially for PTZs that are used outdoors, the weight of the protective cover is often too large, and there is often the problem that the PTZ does not move (especially the vertical direction does not move);

The outdoor pan/tilt is faulty or even damaged due to poor ambient temperature, too low or waterproof, antifreeze, etc.

When the distance is too far, the operating keyboard cannot remotely control the camera (including the lens) and the pan/tilt through the decoder. This is mainly because when the distance is too far, the attenuation of the control signal is too great and the control signal received by the decoder is too weak. At this time, a relay box should be installed at a certain distance to amplify the control signal.

9, the matrix host does not clean the image switch. This kind of failure is generally manifested in the screen after the cut, such as superimposed with other screen disturbances, or other lines of image synchronization signal interference. This is caused by the poor quality of the matrix switch and the lack of isolation between the images. If a radio frequency transmission system is used, it may also be caused by the system's cross-talk modulation and excessive modulation.

10, the monitor image contrast is too small, the image is light. If this phenomenon is not the problem of controlling the host computer and the monitor itself, it means that the transmission distance is too far and the video transmission line is attenuated too much. In this case, the line amplification and compensation device should be added.

11, the image clarity is not high, the details of the missing part, serious color signal may be missing or color saturation is too small and other phenomena, which is the high-frequency end of the image signal loss is too large, that is more than 3MHz frequency signal caused by the loss. In this case, the transmission distance is too long and the high-frequency signal is attenuated too much, and there is no amplification compensation device in the middle; or because the distribution capacitance of the video transmission cable is too large; or because of the convergence between the core and shielded wires in the transmission line during transmission. The equivalent capacitance of the distribution.

12, color distortion. This is a fault phenomenon that easily occurs in long-distance video baseband transmission. It is also mainly caused by the transmission line being too long, causing excessive attenuation in the high frequency band of the signal. In this case, a compensator should be added.

A large-scale television monitoring system that operates in conjunction with burglar alarms is a high-tech and complex system. Although various failure phenomena may occur, as long as good quality is applied to the selection of equipment and equipment, and construction is strictly conducted in accordance with standards and specifications, there are generally no major problems. Whenever there is a problem, as long as you are calm and analytical, you can solve the problem faster.
