Abstract: This invention provides a high voltage thyristor valve multi-injection test method, it can meet one way valve and double valve operation test and over current test requirements. It has high equivalence and good flexibility. It includes FACTS double way thyristor valve and normal direct current thyristor valve operation tests and over current test. This method is novel, flexible, can carry out many different test and their mixture test and including the high voltage thyristor valve different tests.

Abstract: The present invention relates to a test equipment of direct current thyristor valve, and particularly relates to a fault current test equipment of direct current thyristor valve. This present invention equipment includes high voltage low current circuit and low voltage high current circuit, said test equipment includes fault current circuit, said fault current circuit includes resonant circuit, said high voltage low current circuit, low voltage high current circuit and fault current circuit are all connected with the thyristor sample Vt respectively. In his present invention, the thyristor sample is first heated through the high voltage circuit and low voltage high current circuit to reach the stable state. And then shut off the switch and carries out the test using the fault current which is produced by the fault current circuit. This prevents the power system from the short-circuit impact.
