MULTI-INJECTION TEST METHOD FOR HIGH VOLTAGE THYRISTOR VALVE

摘要

A multi-injection test method for a high voltage thyristor valve includes an alternating and direct current super-current injection test method, a voltage double injection test method and a resonance voltage injection test method. An alternating and direct current large current injection loop (3), a voltage dual injection loop (2) and a resonance voltage injection loop (6) are connected individually with a sample valve via an isolating valve. The alternating and direct current super-current injection test method utilizes the loop capable of generating the alternating and direct super-current to inject the alternating or direct super-current to the sample valve, and the voltage dual injection test method utilizes the loop capable of generating voltage injection to inject a positive and negative high voltage to the sample valve and the change rate thereof, high current change rate, and the resonance voltage injection test method utilizes the loop capable of generating the resonance high voltage to inject the resonance high voltage to the sample valve.
