Abstract

The invention discloses a sulfur hexafluoride gas density relay. The sulfur hexafluoride gas density relay comprises a shell, a signal control part and an indicating value display part, wherein the signal control part and the indicating value display part are arranged in the shell and are relatively independent. The signal control part comprises a control base, a control end seat, a control Burdon tube, a control temperature compensation piece, a control connecting arm, a control signal regulating piece and a plurality of control microswitches serving as signal generators. The control microswitches are arranged in the mode that the width direction of operating handles of the control microswitches is perpendicular to the width direction of the Burdon tube. The indicating value display part comprises a display Burdon tube, a display temperature compensation piece, a display base, a display end seat, a display machine core, a pointer, a display connecting arm, a display signal regulating piece and a plurality of display microswitches serving as signal generators. The sulfur hexafluoride gas density relay can achieve overpressure alarming and control, the accuracy of dense relays is improved to the maximum extent, the thickness of the dense relays is reduced, the application range of the dense relays is enlarged, and the sulfur hexafluoride gas density relay is suitable for being applied to various occasions.
