The invention relates to a spacecraft electrical interface docking test system, and belongs to the technical field of spacecraft rendezvous and docking test. The testing system comprises a guide rail, a turntable and a fixing frame, the turntable comprises a seat body and a rotating body, the seat body is in guide movement fit with the guide rail, the rotating axis of the rotating body extends up and down, and the fixing frame is supported and fixed on the rotating body; the fixing frame is provided with an electrical interface, and the axis of the electrical interface perpendicularly intersects with the rotating axis of the rotating body. The test system further comprises a targeting interface, and the targeting interface is arranged in the translation direction of the rotating disc so as to be in rendezvous butt joint with the electrical interface. And a detection loop is connected between the target interface and the electrical interface and comprises a power supply, a voltmeter for measuring voltages at two ends of the interface and an ampere meter for measuring current in the detection loop. According to the invention, the rendezvous and docking process of spacecrafts can be simulated, and the system temperature rise condition, the transmission characteristic, the docking dynamic process, the vibration characteristic of the fixing frame, the insertion and extraction force, the error angle and the like in the docking process of the electrical interfaces of the spacecrafts can be detected.
