WSA-423 transformer rectifier unit maintenance equipment is disclosed. According to the present invention, the WSA-423 transformer rectifier unit maintenance equipment may comprise: a lamp part for displaying an output progress state; a control part for controlling the proceeding depending on operation conditions; a DC power supply for supplying DC 5V to a WSA-423 transformer rectifier (TRU); and a slidacs to supply AC input to the WSA-423 transformer rectifier (TRU). The test procedure of the maintenance equipment includes a functional test, a no load functional test, a load test 1 (8A), a load test 2 (16A), a load test 3 (24A), a low voltage input test, an overvoltage input test, and a full load test for a WSA-423 transformer rectifier (TRU) test procedure; and a functional test, a low voltage input test, and an overvoltage input test for a WSA-423 solid contactor (SSC) maintenance test procedure. The purpose of the present invention is to enable military maintenance by detecting and identifying a fault location in the own unit and eight kinds of unit modules when the transformer rectifier is out of order. |
