Pay attention to the suitability of choosing ppe

Several matters that must be paid attention to in the operation process of portable DC high voltage generator DC high voltage generator is a kind of precise electric measuring instrument. If it is operated improperly, it will not only affect the measurement accuracy of the instrument, but also shorten the service life of the instrument. Therefore, novices must pay attention to the following six issues when operating a high voltage DC generator:

1. Regardless of which equipment is purchased by the DC high voltage generator, before use, it is necessary to look at the specification to understand the working principle and operation flow of the equipment.

2. The DC high voltage generator shall be equipped with two obvious disconnection points before the working power enters the tester. When changing the tested product and wiring, the operating power supply disconnection point shall be disconnected first;

3, DC high voltage generator before testing the first test high voltage DC generator control box, double pressure tube and the test product ground wire is connected, the test circuit ground wire should be according to the point shown in the specification;

4. The DC high voltage generator discharges the large capacitive test subject with a discharge resistance rod of 100Ω/V to discharge the test article. When discharging, the discharge rod cannot immediately contact the test sample. The discharge rod should be gradually approached to the test sample first. To a certain distance, the air gap begins to dissociate and there is a buzzing sound. When there is no sound, the discharge rod can be used to discharge the ground terminal, and finally it is directly connected to the ground discharge;

5. When the DC high voltage generator DC high voltage is 200KV or more, although the tester wears insulating shoes and is located outside the safe distance, due to the influence of the HVDC ion space electric field distribution, several nearby standing bodies will be brought on. For different DC potentials, the test personnel should not shake hands or touch the grounding point with hands, otherwise there will be slight electric shock phenomenon. This phenomenon is more obvious in dry areas and winter, but it will not cause harm to people because of the small energy.

6. After the DC high-voltage generator is tested, the grounding wire must be hung to the high-voltage output end to remove the high-voltage wire.

Of course, in actual operation, we may encounter various conditions, so after the unit or enterprise purchases a new DC high voltage generator, the operator must have a test equipment operation license, one is to ensure the personal safety of the operator. Secondly, it can also allow the equipment to "get on the job" as soon as possible.

Sodium Molybdate

Sodium molybdate is an inorganic substance with the chemical formula Na2MoO4, which is a white rhombus crystal. Molybdenum trioxide can be obtained by oxidative roasting of molybdenum concentrate, leaching with liquid alkali to prepare sodium molybdate solution, and then suction filtration, concentration, cooling, centrifugation and drying. Determination of alkaloids and glyغير مجاز مي باشدides. Determination of Total Phosphorus and Available Phosphorus Content in Superphosphate Phosphate Fertilizers. Check protein-free blood filtrate and serum protein. Corrosion inhibitor. H medium, T medium, modified Nisch medium, MS medium and RM medium were prepared in haploid breeding. Make paint.
