Research on intellectualization of 126kV SF6 circuit breaker
To realize Intelligent transformation based on the traditional 126kV SF6 circuit breaker, firstly, selection and installation of sensor is discussed, and the rotating shaft which connect the transmission shaft and the angular displacement sensor is improved. Secondly, to determine the heater power, the heater is calculated and studied, based on the temperature changing and spatial size of mechanism box; Finally, how to select the water vapor content transmitter is studied, in order to realize condition monitoring SF6 gas.
