At present, many power test equipment are intelligent one-button operation, many power test equipment operation is relatively simple, but still need to master certain professional knowledge and operation steps. The following is to introduce the detailed experimental steps of vacuum switch vacuum tester.
1. Ensure that the vacuum circuit breaker is insulated from the outside world and does not leak or reverse charge during the experiment.
The following aspects need to be dealt with:
A. Grounding at both ends;
B. Transformer;
C, lightning arrester;
D. arc suppression capacitance;
E. Sensors.
2. Ensure that the vacuum circuit breaker is clean and dry
3. Ensure the opening distance of vacuum circuit breaker (breaking)
4. Hang the electromagnet sampler, align the white scale line with the middle position of the vacuum circuit breaker, and bind the electromagnet and vacuum circuit breaker with straps (impulse voltage will produce impact force during the experiment, so as to avoid the damage of the vacuum circuit breaker).
5, according to the color of the test line and the size of the plug-in connection line, high pressure clamping at one end of the vacuum circuit breaker far away from the electromagnet, yellow and green lines must be connected to the electromagnet and then connected to the instrument.
6. Choose the tube type that matches the vacuum circuit breaker (the diameter of the vacuum circuit breaker with sheath shall prevail).
7. Turn on the power supply after the preparation work is done: first press leak detection and determination to see whether the vacuum circuit breaker leaks or is qualified; Then according to the measurement quantitative, see how much vacuum degree is, print the test results (display: 3.26E-4Pa is 3.26×10-4 Pa pascals).
National standard of vacuum circuit breaker: the factory standard is less than 1.33×10-3 Pa PASCAL;
A PASCAL larger than 6.62×10-2 Pa is not qualified
8, discharge: according to the leakage detection to reduce the magnetic field voltage, turn off the power supply, big clip to the ground, single pull out the yellow and green test line on the instrument (hand do not touch the exposed part of the plug-in), discharge is completed, other test lines can be disassembled at will.
9. Install the accessories and complete the test.
