Abstract
The invention discloses an operating shaft of a high-voltage switch cabinet ground switch interlocking mechanism. The invention relates to the field of an electric appliance and aims at providing an operating shaft of a high-voltage switch cabinet ground switch interlocking mechanism, which has favorable insulating property and can avoid discharge and grounding security accidents. The technical scheme for realizing the purpose of the invention is as follows: the operating shaft of a high-voltage switch cabinet ground switch interlocking mechanism comprises a shaft body and is composed of three parts, wherein one operating shaft part which is adjacent to a bare bus bar and a ground switch is an epoxy resin-glass fabric rod, both sides of the epoxy resin-glass fabric rod are respectively provided with one operating shaft part which is formed by machining metal materials, and the three parts of the operating shaft are connected into an operating lever by two sleeves and four pins. The invention is used for detecting and maintaining a high-voltage switch cabinet.
Description
Technical field:
The present invention relates to a kind of appliance field, particularly a kind of operating axis of high-tension switch cabinet earthed switch interlocking gear.
Background technology:
Operating axis in the existing mid-cabinet earthed switch of the high pressure interlocking gear is a metal processing piece, the one phase bare bus bar and the electric clearance between the ground connection operating axis of operating axis side are generally less, can not satisfy the safety requirements of normal operation, the way that solves is that the operating axis at the electric clearance place of influence safety partly installs insulated tube additional, but this insulated tube in use easily takes place to wear out, corrosion etc. causes its decreasing insulating, cause contiguous phase bus to the operating axis discharge of earthed switch interlocking device, ground connection, cause personnel and equipment breakdown.
Summary of the invention:
The purpose of this invention is to provide a kind of good insulation preformance and can not discharge, the operating axis of a kind of high-tension switch cabinet earthed switch interlocking gear of the security incident of ground connection.The present invention realizes that the technical scheme of goal of the invention is, a kind of operating axis of high-tension switch cabinet earthed switch interlocking gear, comprise axis body, it is characterized in that: operating axis is made up of three parts, partly be the glass fabric of epoxy resin rod wherein with an operating axis that bare bus bar is adjacent with earthed switch mutually, respectively there is one by the operating axis of metal material in the both sides of this glass fabric of epoxy resin rod through being processed into, the two ends of described glass fabric of epoxy resin rod place the hole of two sleeve pipe the inners respectively, the hole of these two sleeve pipe outer ends matches with the inner that affiliated metal is made axle respectively, two pins insert in respectively in the radial hole of the radial hole of described two sleeve pipe the inners and glass fabric of epoxy resin rod termination, and two pins insert in respectively in the radial hole of the radial hole of described two sleeve pipe outer ends and two metallic operation rod terminations in addition.The present invention has safe and reliable remarkable advantage compared with the prior art.
Description of drawings:
Accompanying drawing is the structural representation of operating axis of the present invention.
Embodiment:
In conjunction with following embodiment the present invention is described in detail, in order to solve the existing insulated tube problem that is corroded and causes insulation property to reduce easily aging and affected by environment, the present invention is divided into three independent parts with operating axis, wherein need to have the insulation operating axis 4 that insulation property are partly made with the glass fabric of epoxy resin rod, and two parts 1 in addition of operating axis, 5 make through machining by designing requirement for metal material, with operating axis 1,5 and 4 are set in respectively in the hole of two sleeve pipes 2, insert in sleeve pipe and operating axis 1 by 4 each pin 3, make the operating axis 1 at operating axis 4 and its two ends in the radial hole on 5,5 connections are in aggregates.Make because operating axis 4 is the glass fabric of epoxy resin rod, its good insulation preformance and corrosion resistance are superior, thereby this operating axis has the advantage that security performance is good and use is long.
