GIS equipment high-voltage cable terminal test cabin

The invention provides a GIS equipment high-voltage cable terminal test cabin. The GIS equipment high-voltage cable terminal test cabin comprises a tank body and a withstand voltage detection device arranged in the tank body; a wiring hole for a high-voltage cable to penetrate through is formed in the bottom of the tank body; the withstand voltage detection device comprises a power supply module,an ultrasonic probe, a partial discharge probe, an optical camera and a central processing module; the ultrasonic probe is used for collecting an ultrasonic signal generated when the high-voltage cable terminal discharges; the partial discharge probe is used for collecting a partial discharge signal generated when the high-voltage cable terminal discharges; the optical camera is used for collecting an arc signal generated when the high-voltage cable terminal discharges; and the central processing module is used for judging the voltage withstanding performance of the high-voltage cable according to the received ultraso
