Problems solved by technology

[0002] In the traditional metal-enclosed combined electrical equipment (HGIS) manufactured by the applicant, the existing isolating switch and its grounding switch are vertically arranged relative to the horizontally arranged circuit breaker unit, because the opening and closing directions of the isolating switch and the circuit breaker are different and The installation height is higher than the circuit breaker, so there are disadvantages of disassembly, complicated installation, high environmental requirements, and inconvenient installation and transportation.
In addition, the operating link of this kind of vertical isolating switch and its grounding switch is relatively long, which affects the accuracy and reliability of the switch action; at the same time, its shell is made of castings. Due to its large size and shape Complicated, so many casting defects make machining costly

Abstract

Aiming at resolve the defects that assemblage and maintenance are not convenient of traditional isolating switch device, the invention provides an isolating switch device that the operation is simple, insulation is strong, performance is more reliable, it includes shell, operating mechanism, a isolating switch and at least one grounding switch, the isolating switch includes act end screening can and spacing movable contact, static end screening can and spacing stationary contact; the grounding switch includes grounding act contact which is on lower side wall of the shell and grounding static contact which is on lower side of the act end screening can or static end screening can. It characterized in that the spacing movable contact and spacing stationary contact are arranged in level linear type, the action direction is uniform with the axial center of shell, the act end screening can and static end screening can are separately fixed to two ends of the shell via insulated basin, the operating mechanism adopts two separated drive and connection mechanism of separating and grounding to realize the non-interference of separating switch and grounding switch.

Description

technical field [0001] The invention relates to a switchgear for a high-voltage electrical appliance, in particular to a gas-insulated isolating switchgear. Background technique [0002] In the traditional metal-enclosed combined electrical equipment (HGIS) manufactured by the applicant, the existing isolating switch and its grounding switch are vertically arranged relative to the horizontally arranged circuit breaker unit, because the opening and closing directions of the isolating switch and the circuit breaker are different and The installation height is higher than the circuit breaker, so there are disadvantages of disassembly, complicated installation, high environmental requirements, and inconvenient installation and transportation. In addition, the operating link of this kind of vertical isolating switch and its grounding switch is relatively long, which affects the accuracy and reliability of the switch action; at the same time, its shell is made of castings. Due to ...
