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.

    本发明公开了一种精准定位的高压互锁装置及判断方法,包括控制器供电电源、控制器内部电阻、高压设备连接区和电压采集模块;所述控制器内部电阻与高压设备连接区串联连接;所述电压采集模块安装于高压设备连接区的正负两端,用于采集高压设备连接区的电压;所述高压设备连接区内设有若干个高压连接器互锁端子以及与各个高压连接器互锁端子相对应的接线电阻;所述高压连接器互锁端子之间串联连接,所述高压连接器与其相对应的接线电阻并联连接,所述接线电阻的阻值互不相同;与现有技术相比,本发明可以精准定位到详细的故障连接点,不需要针对所有高压连接点进行检测,极大的减少了售后的工作量,避免了因为检修导致二次故障的发生。
