High-voltage test in the test room transformer safety need to pay attention to six major points
1. When conducting high-voltage AC/DC tests, two or more persons must participate in the test, and clear division of labor must be clearly defined to clarify the method of contact between them. And there are special people to monitor the scene safety and observe the test status of the test product;
2. Test transformer and control box should have reliable grounding;
3, high voltage test transformer test process, the boost speed can not be too fast, it must not be allowed to suddenly full voltage or power off;
4. In the process of step-up or pressure test, if any of the following abnormalities are found, immediately step down the pressure, cut off the power supply, stop the test, and check the cause before doing the test. 1 The voltage meter pointer swings a lot; 2 the smell of burning insulation is found to be odor and smoke is emitted; 3 there is abnormal sound in the tested product.
5, high voltage test transformer test, if the sample short-circuit or breakdown breakdown, control box over-current relay work, this time, the regulator back to zero, and cut off the power before the sample can be removed.
6. When conducting capacitance test or DC high-pressure leakage test, after the test is completed, reduce the voltage regulator to zero and cut off the power. Then, discharge the high-voltage terminal of the test sample or capacitor to the ground with the discharge rod to avoid The potential remaining in the capacitor is at risk of electric shock.
