Recently, Wuhan UHV after-sales team received an invitation from a customer in Beijing to arrive at the test site to provide training and after-sales technical services for its on-site test personnel, and the instrument used for the training is the UHV(V) 낙뢰 충격 전압 발생기 테스트 장치.

Impulse voltage test system is a test equipment to simulate impulse high voltage. In real life, impulse high voltage is often encountered. For example, in nature, lightning strikes thunder, lightning will appear very high impulse current and voltage, around the high impulse voltage will also be induced; Another example, in the power system, switchgear closing and breaking operation will also lead to transient impulse voltage. These transient impulse voltage amplitude is often in tens of kilovolts or hundreds of kilovolts or more, will lead to equipment damage and jeopardize personal safety, so the impact voltage test research is very necessary. On the other hand, it is also meaningful to simulate the natural lightning phenomenon for the study of discharge mechanism.

 Here we need to put forward in particular is that the output waveform of the impact voltage test circuit and the test specimen, the test equipment components access and the distance of the surrounding grounding body are closely related, so the difficulty of the impact test and most of the work is the work of wave modulation. Can get to meet the standard requirements of the impact waveform is the key to the impact test.

The customer mainly produces 10kV vacuum circuit breaker, in the factory inspection, need to carry out lightning impact test, after the explanation, the customer can independently complete the instrument wiring and voltage test, the customer site responsible person also expressed that the after-sales service is very satisfied with this time, the after-sales technical service has been successfully completed!
