The invention relates to a piece of high-voltage direct-current power transmission light-controlled converter valve TVM plate automatic test equipment comprising a control unit, an alternating-current power supply unit, a voltage acquisition unit, an impulse voltage generation unit, and an RC circuit. The control circuit is connected with the alternating-current power supply unit and the impulse voltage generation unit in a control manner. The alternating-current power supply unit and the impulse voltage generation unit are connected with the RC circuit through a first voltage output branch and a second voltage output branch respectively. The RC circuit is connected with a voltage output port which is connected with a voltage input port corresponding to a TVM plate. The voltage acquisition unit is connected with the first voltage output branch and the second voltage output branch, and the voltage acquisition unit is further connected with the control unit. The control unit is connected with a back-check signal transmitting port of the TVM plate through a back-check signal receiving port. By using the TVM plate automatic test equipment to test a light-controlled converter valve TVM plate, automatic TVM test is realized, the test efficiency is improved, and the error probability is effectively reduced.
