In the process of using power test equipment, there are some matters needing attention. Here are the precautions of vacuum switch vacuum tester:
1. Vacuum degree test should be carried out in sunny and dry weather, and the vacuum bubble surface should be wiped clean. Leakage caused by dirty vacuum bubble surface will seriously affect the actual test result of vacuum degree. For the vacuum degree test of the same vacuum switch, the interval of each test should not be less than 10 minutes. Otherwise, the ionized air in the tube does not return to normal enough to distort the test results.
2. It is recommended not to test the vacuum degree of the same vacuum switch more than 3 times a day.
3. When testing vacuum degree, leak should be detected first, and quantitative test should be carried out after passing leak detection.
4. The red cable connected to the red clip is the high voltage cable, and the black cable connected to the black clip is the ordinary cable. In the actual wiring process, do not connect the black ordinary cable to the high voltage output, in order to avoid serious leakage resulting in test failure or endanger the human body and equipment.
5. When installing the excitation coil, the positioning indication line points to the joint of the arc extinguishing chamber.
6, the test process, the human body can not contact the high voltage and magnetic field voltage output end, the tester shell should be connected to the ground.
7. High voltage output line and ion current line should be separated to prevent interference.
8, the magnetic field electric pressure line, skip short circuit, otherwise serious damage to the instrument and personal safety! Before the experiment, the yellow and green lines should be connected to the electromagnet and then to the instrument; After the test, separate pull out the yellow and green test line on the instrument (do not touch the exposed part of the plug-in).
9. After the test, the power should be turned off and the high voltage output end should be short-circuited to the ground to avoid electric shock from the residual voltage on the charging capacitor.
