Description

A kind of 110kV isolating switch

(1) technical field

The utility model, in particular to a kind of 110kV isolating switch, belongs to a kind of structure of SF6 gas insulation metal seal combined electrical apparatus (GIS) isolating switch design.

(2) background technology

Present stage, the first-selected three station-type structures of isolating switch in 110kV gas insulating metal closed type combined electrical apparatus (GIS), in this structure, inner conductor, electric appliance casing etc. adopt casting pattern in a large number, compared to section bar, cast member inferior position is more obvious: need out casting mould, a kind of foundry goods needs a kind of mould, and die cost is high; Casting qualified rate is low, and especially in hectic fever summer and low temperature winter, it is lower that climate affects qualification rate; When completing same function, casting quality, much larger than the part of shape extrusion, wastes material.This project organization is complicated, processing and manufacturing cost is high, and product competitiveness is poor.

(3) summary of the invention

The utility model, in order to make up the deficiencies in the prior art, provides that a kind of compact conformation is succinct, dependable performance, can be used as the 110kV isolating switch that standard module realizes the modular design of GIS.

The utility model is achieved by the following technical solution:

A kind of 110kV isolating switch, comprise isolating switch conductor, isolating switch action contact, main circuit conductor, inspection earthing device conductor, line-to-ground switching device and casing for electric appliances, it is characterized in that: described isolating switch conductor, isolating switch action contact, main circuit conductor, inspection earthing device conductor and line-to-ground switching device are all installed on the inside of casing for electric appliances, isolating switch conductor and line-to-ground switching device are installed on the housing of the casing for electric appliances left and right sides respectively, main circuit conductor is installed on the middle part of casing for electric appliances, isolating switch action contact to be arranged between main circuit conductor and isolating switch conductor and to link with the mechanical action device be fixed on casing for electric appliances, inspection earthing device conductor is installed on the housing of casing for electric appliances above isolating switch action contact, isolating switch action contact can three position reciprocating actions under the drive of mechanical action device: contact with main circuit conductor, do not contact with centre position and with isolating switch conductor contact, both realized connecting, isolation, ground connection three kinds of operating modes.

The beneficial effects of the utility model are: the utility model simplifies main circuit conductor in a large number, casing for electric appliances, the cast type structure of the complexity used in action and fixed contact and earthing device, perfection on the basis of profile design manufacture converted products parts is generally adopted to realize the various functions of isolating switch, both realized connecting, isolation, ground connection three kinds of operating modes and there is opening-closing bus switching current and perception, the ability of capacity current, compact conformation is succinct, dependable performance, can be used as the modular design that standard module realizes GIS, simplify product structure, improve properties of product, reduce product cost, be suitable for wide popularization and application.
