Abstract

The invention discloses an ultra-small gas density relay. The ultra-small gas density relay is characterized in that the ultra-small gas density relay comprises a signal mechanism and an indication display mechanism which are connected together; the signal mechanism is internally provided with a bellows used for detecting gas density in sulphur hexafluoride electrical equipment and a micro switchacting as a contact; the indication display mechanism comprises a display Baden tube, a display temperature compensation element, a display end seat, a movement, a dial, a pointer and a display base;both one end of the display Baden tube and one end of the display temperature compensation element are fixed on the display end seat; the other end of the display Baden tube is connected on the display base; the other end of the temperature compensation element is connected with the movement respectively through a connecting arm and a display connecting rod, or the other end of the display temperature compensation element is directly connected with the movement; the pointer is mounted on the movement and arranged in front of the dial. The ultra-small sulphur hexafluoride gas density relay hasthe advantages of full scale range display, good vibration resistance, high precision, easy realization and easy promotion and application.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an ultra-small sulfur hexafluoride gas density relay. Background technique [0002] At present, the signal mechanism (signal control part) of the sulfur hexafluoride gas density relay used to monitor the density of sulfur hexafluoride gas in the electrical equipment of sulfur hexafluoride generally uses bellows as the pressure measuring element and micro The indication and display mechanism of the sulfur hexafluoride gas density relay generally uses the bellows in the signal mechanism as the pressure measuring element. At the same time, the indication and display mechanism indicates the indication of sulfur hexafluoride gas density through the mechanical deformation of the bellows itself due to pressure and through the movement control pointer. However, for this kind of sulfur hexafluoride gas density relay, its display mechanism based on the bellows has a small display ...
