Online monitoring system of high-voltage isolation knife switch

The utility model provides an on-line monitoring system of a high-voltage isolation knife switch, comprising a flight time measuring assembly which comprises a flight time sensor, a microprocessor anda wireless transmit-receive module. The time-of-flight sensor is arranged on a static contact of the high-voltage isolation knife switch and used for measuring the distance between a moving contact and a static contact of the high-voltage isolation knife switch and sending a measurement signal to the microprocessor, and the microprocessor judges the opening and closing state of the high-voltage isolation knife switch and uploads the state to the upper-level control module through the wireless receiving and sending module. The time-of-flight sensing assembly is used for measuring the distancebetween the moving contact and the static contact so as to judge the opening and closing states of the high-voltage isolation knife switch. 本实用新型提供一种高压隔离刀闸的在线监测系统，包括飞行时间测量组件，所述飞行时间测量组件包括飞行时间传感器、微处理器以及无线收发模块，所述飞行时间传感器设置于高压隔离刀闸静
