Abstract

一种线缆辅助设备，包括单向导通元件(301)和接地极(102)，单向导通元件的一端与线缆(302)中的导体结构连接，另一端与接地极连接，通过对单向导通元件施加不同极性的电压，使单向导通元件的通断状态不同，当单向导通元件的通断状态为导通状态时，线缆中的导体结构通过单向导通元件与接地极导通，进而可以实现对导体结构直流电阻的检测；而当单向导通元件的通断状态为断开状态时，单向导通元件阻断导体结构与接地极之间的连接，进而可以实现对绝缘结构的绝缘电阻的测试。便于进行导体结构的直流电阻和绝缘结构的绝缘电阻的测试，从而可以对线缆的故障进行全方位的排查，及时发现线缆的损伤，降低后续定位维修成本。
