This present invention provides a high power electronic device which is used for transforming the alternating current into the direct current, or transforming the direct current into the alternating current: a thyristor valve module, there are two same thyristor valve segments in the whole thyristor valve module; each segment includes saturated reactor, thyristor valve unit, direct current equalizing resistor unit, acquiring energy unit, damped resistor unit, damped capacitor unit, gate series unit and water cooling system. This device series connects the thyristor valves to meet different transmission powers and different voltage ranks. This device is the key element of the high voltage direct current transmission. It can be used for different voltage ranks AD transmission system and can also be used for different voltage ranks DC system, including the ultra-high voltage 800 kV and above system.

Thyristor valve module

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. Further more, the peak current and the current duration of the fault current circuit can be adjusted flexibly by changing the voltage of the adding energy circuit.

Fault current test equipment of direct current thyristor valve

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.

High voltage thyristor valve multi-injection test method

The present invention provides a novel direct current thyristor valve saturated reactor includes: case, winding in the case, iron cores, cooling fins, pipes and press fit mechanism. The iron cores are coupled with winding. The invention having the following advantages: simple, modular design, low connection capacity of the wingding, fixed dimension, winding and irons well-cooled, small noise and vibration. The saturated reactor is particularly suitable used as the positive saturated reactor for high voltage current thyristor valve.
