Development of a Portable On-off Detection Device for Grounding Down Lead

设计了一种便携式接地引下线通断检测装置,利用二极管的单向导通性来检测接地引下线通断情况。实际测试证明,该装置可在高压试验前准确、快速检测接地引下线通断情况,并能测试检修电源电压,以保证设备安全运行及试验人员的安全。

A portable on-off detection device for grounding down lead is designed,which uses the unidirectional conduction of the diode to detect the on-off state of grounding down lead.The actual test proves that the device can accurately and quickly detect the on-off state of the grounding down lead before the high voltage test,and can test the maintenance power supply voltage so as to ensure the safe operation of the equipment and the safety of the test personnel.
