More Information
Summary:An isolation frame and a contact knife static end are fixed on the circuit breaker, a voltage sensor is fixed on the isolation frame, a knife holder is fixed on the voltage sensor, the voltage sensor comprises a sensor insulation column, a substrate and a secondary line, the sensor insulation column is provided with a threaded hole, the substrate is provided with a fixing hole, and the secondary line is fixed on the substrate. The voltage sensor replaces an isolation pillar of the isolation switch, so that the isolation switch and the voltage sensor can be installed at the same time, the structure is simple, on-site installation and transportation are facilitated, and the production and transportation cost is low. 本实用新型公开了一种断路器，隔离架和触刀静端固定在断路器上，电压传感器固定在隔离架上，刀座固定在电压传感器上，电压传感器包括传感器绝缘柱、基板和二次线，传感器绝缘柱上设有螺纹孔，基板上设有固定孔，电压传感器代替隔离开关的隔离支柱，不仅可实现隔离开关和电压传感器同时加装，而且结构简单，便于现场安装和运输，生产和运输成本低。
