What are the test methods for force and high pressure testing equipment? High voltage test is a common and effective means to detect the normal operation of power equipment, of course, the test method is also very.

1. System for power frequency AC test

The test method of power frequency AC high voltage is realized by the controller of the power supply, the regulator and the protection of the ball gap, etc. The main function and function of the regulator in the whole system is to adjust the size of the commercial test voltage and control the speed of the voltage change.

2, about the dc withstand voltage and ac withstand voltage

Considering the problems existing in the low-frequency AC withstand voltage test system, the prototype with large capacity requires relatively large capacity of the test transformer for the power-frequency test, and the burden of the test equipment is large, so the field test is very troublesome. In this case, the capacitive current is proportional to the frequency of the test voltage, so the equipment using 0.1Hz ultra low frequency test is proposed, its capacity is only 1/50 of the commercial frequency.

3. Test system for DC withstand voltage

Generally speaking, the voltage withstand of facilities can be tested by the way that power-frequency high-voltage rectifier plays the initial role of DC high-voltage generator, but in practice, it will be replaced by commercial voltage double rectifier high-voltage generator due to its large volume and poor stability. At present, due to the advantages of simple circuit and strong load capacity, the latest power frequency voltage rectifier high voltage generator is widely used in the voltage test of equipment.
