CN205611151U - Novel metallic shield body - Google Patents

Abstract

The utility model discloses a novel metallic shield body, including cylinder copper shield net, the cylinder copper shield is covered with the rhombus aperture on the net, and the last lower extreme of cylinder copper shield net is giving prominence to the ring in shielding net mesh wall, and ring itself is formed by copper shield net coiling, the lead -out wire of being connected with cylinder copper shield net adopts thread insert or soft stranded conductor. The utility model discloses rational in infrastructure, after novel shield was loaded onto to the copper bar outside, because the shield adopts copper material, resistance was less, the utility model discloses specific shape structure, field distribution is even, and in fact the high -pressure side becomes an equipotential high voltage live body, for cylindric uniform electric field, but greatly reduced product partial discharge volume.

Description

Novel metal shield

Technical field

This utility model relates to a kind of shield.

Background technology

Switch cubicle shield in the past, owing to bus bar edge has tip, easily causes the electric discharge of bus casing inner tip, And busbar cross section structure is rectangle, causes internal electric field skewness, thus inside bus casing, produce arc dodge.

Summary of the invention

The purpose of this utility model is to provide a kind of rational in infrastructure, effectively reduces the novel metal of product partial discharge quantity Shield.

Technical solution of the present utility model is:

A kind of novel metal shield, is characterized in that: include cylindrical shape copper shield net, cylindrical shape copper shield is covered with Pedicellus et Pericarpium Trapae on the net Shape aperture, the upper and lower side of cylindrical shape copper shield net is the annulus protruding from gauze screen net wall, and annulus itself is by copper shield net volume Around forming；The lead-out wire being connected with cylindrical shape copper shield net uses threaded insert or soft whipping wire.

This utility model is rational in infrastructure, after loading onto Novel shielding body outside copper bar, owing to shield uses copper material, electricity Hinder less；The specific shape and structure of this utility model, Electric Field Distribution is uniform, and actually high-pressure side becomes an equipotential high pressure Electrical body, for cylindrical homogeneous electric field, can be substantially reduced product partial discharge quantity.

Accompanying drawing explanation

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of one embodiment of this utility model.

Detailed description of the invention

A kind of novel metal shield, including cylindrical shape copper shield net 1, cylindrical shape copper shield is covered with rhombus aperture on the net, The upper and lower side of cylindrical shape copper shield net is the annulus 2 protruding from gauze screen net wall, and annulus itself by copper shield net volume around forming； The lead-out wire 3 being connected with cylindrical shape copper shield net uses threaded insert or soft whipping wire.
