The live working of the power distribution network is an effective means for improving the reliability of power supply and the satisfaction degree of power utilization of users, and is a conventional mode for overhauling the power distribution network at present. When the distribution network is in live working, the line equipment of the working point is in a normal live working state, and the working personnel performs standard operation according to the safety operation requirement to ensure the personal safety of the working personnel. At this time, if single-phase or multi-phase power is not available due to sudden failure, operators are exposed to operation overvoltage and abnormal voltage rise due to potential power restoration and strong power transmission operation, the amplitude of the operation overvoltage is 3-4 times of the normal voltage value, insulation shielding breakdown is possibly caused, and personal injury and death of the operators are caused. In the live working process of an actual power distribution network, whether the operation line equipment runs normally, whether the operation line equipment breaks down or not and whether the operation line equipment is out of power are judged, and generally, the operation line equipment is judged by simply testing the power once through electroscopes with corresponding voltage grades before operation. In the whole process of live working, a corresponding real-time detection device is not used for monitoring whether the line equipment is in a normal running state, if the line equipment suddenly breaks down and has power failure due to non-live working during the live working, field working responsible persons and operating personnel cannot timely know whether the line or the equipment is in voltage loss due to wearing insulating protective tools on the field, and at the moment, a large potential safety hazard of overvoltage operation exists.
