The invention discloses an accurate positioning high-voltage interlocking device and a judgment method. The accurate positioning high-voltage interlocking device comprises a controller power supply, a controller internal resistor, a high-voltage equipment connection area and a voltage acquisition module, the internal resistor of the controller is connected in series with the high-voltage equipment connecting area; the voltage acquisition modules are installed at the positive and negative ends of a high-voltage equipment connection area and are used for acquiring the voltage of the high-voltage equipment connection area. A plurality of high-voltage connector interlocking terminals and wiring resistors corresponding to the high-voltage connector interlocking terminals are arranged in the high-voltage equipment connecting area; the interlocking terminals of the high-voltage connectors are connected in series, the high-voltage connectors are connected with the corresponding wiring resistors in parallel, and the resistance values of the wiring resistors are different from one another; compared with the prior art, the method has the advantages that detailed fault connection points can be accurately positioned, all high-voltage connection points do not need to be detected, the after-sales workload is greatly reduced, and secondary faults caused by maintenance are avoided.
