摘要
A high-precision gas density relay, comprising a housing, a base, an end seat, a Bourdon tube, a temperature compensation element, a signal regulation mechanism, and a plurality of microswitches. The microswitches are button microswitches. The density relay further comprises microswitch contact trigger elements made of elastic material. One end of each microswitch contact trigger element is fixed inside the housing, and the other end is arranged corresponding to a button of a button microswitch, abutting the button of each button microswitch in one-to-one correspondence. When the gas density value changes, the Bourdon tube and the temperature compensation element generate displacements, which successively drive the microswitch contact trigger elements through the signal trigger mechanism. The positions of the microswitch contact trigger elements are changed, causing the microswitches to generate a corresponding signal, thereby completing the function of the gas density relay. The present invention has high precision and excellent contact conductivity, and can be suitably applied to SF6 electrical devices.
