Title
(EN) A high-precision SF6 gas density relay and a method for realizing the same
(ZH) 一种高精度SF6气体密度继电器及其实现方法
Abstract
(EN)
A high-precision SF6 gas density relay comprises a gas density relay housing, a base, an end seat, a bourdon tube, a temperature compensation element, a signal regulating mechanism and a plurality ofmicro switches as signal generators arranged in the housing; One end of the contact triggering element of the microswitch is fixed in the housing, and the other end is arranged corresponding to the button of the button-type microswitch and abuts on the button of each microswitch one by one correspondingly. When the gas density value changes, the Baden tube and the temperature compensation elementgenerate displacement, and the displacement sequentially drives the micro switch contact triggering element through the signal triggering mechanism, and the micro switch contact triggering element changes position, so that the micro switch sends out corresponding signals to complete the function of the gas density relay. The density relay of the invention has the advantages of high precision and good contact conductivity, and can be well applied to SF6 electrical equipment.
