Sensor system for external damage prevention on-line monitoring of high-voltage power cable

The invention relates to a high-voltage power cable external damage prevention on-line monitoring sensor system, which comprises a high-voltage cable external damage prevention sensor, a signal conditioning unit and a current sensor, and is characterized in that the signal conditioning unit is connected with the high-voltage cable external damage prevention sensor through a coaxial cable, and the signal conditioning unit is mounted above the current sensor in a plugging manner; the high-voltage cable external damage prevention sensor is installed on a high-voltage cable to be detected. The external vibration condition of the high-voltage power cable can be monitored on line in real time, an operation and maintenance unit can take effective measures in time for stopping, and safe and stable operation of a cable line is effectively guaranteed. The method is mainly used for the operation and maintenance stage of the high-voltage power cable. 本发明涉及一种高压电力电缆防外破在线监测用传感器系统，包括高压电缆防外破传感器、信号调理单元和电流传感器，其中信号调理单元通过同轴电缆与高压电
