Trigger test device for thyristor unit of converter valve

The invention relates to a trigger test device for a thyristor unit of a converter valve. The device comprises a rectifying module, a direct-current output end of the rectifying module is connected with an input end of a test connection module through a power line, and a current on indication module is serially connected to a positive power line or negative power line connected to the output end of the rectifying module. The device further comprises a control module, a test connection module and an indication module, a control contact of the control module is serially connected onto the positive power line or the negative power line, and the test connection module is provide with output ends in corresponding connection with an anode and a cathode of a to-be-connected thyristor unit. The problems of complexity in wiring, inconvenience in operation and unobvious indication in the prior art are solved by the trigger test device for the thyristor unit of the converter valve.
