More Information
Summary:The present utility model discloses a testing system of a power transmission valve. The testing system comprises a voltage regulating transformer, a rectification circuit and two groups of valve units which are connected in series; the voltage regulating transformer is used for outputting AC voltage and generating AC current in a valve unit; the rectification circuit is used for outputting DC voltage and generating DC bias current in the valve unit; and directions of voltage generated by the serial-connected two groups of valve units are opposite. By adopting the testing system, a tested valve unit can be tested under AC current of DC bias, the current stress is the same as that of practical operation, and performance of practical operation can be better tested.
