The invention discloses a high-voltage interlocking device. The high-voltage interlocking device comprises a power supply Vcc (1), a relay 1 (2), a normally closed switch 1 (3), a coil 1 (4), a connector 1 (5), high-voltage equipment 1 (6), a relay 2 (7), a normally closed switch 2 (8), a coil 2 (9), a connector 2 (10), high-voltage equipment 2 (11), a relay 3 (12), a normally closed switch 3 (13), a coil 3 (14), a connector 3 (15), high-voltage equipment 3 (16), a resistor R1 (17), a resistor R2 (18), a resistor R3 (19), a resistor R4 (20) and a control unit (21). The high-voltage interlocking device is used for wire harness connection detection of the high-voltage equipment of a new energy automobile, the wire harness connection state of any piece of high-voltage equipment can be accurately judged by monitoring the voltage change of a detection point, and automobile after-sales personnel are assisted in quickly judging a wire harness disconnection fault point and repairing the automobile. 本发明公开了一种高压互锁装置，所述高
