Abstract
The utility model discloses a novel shield female wire sleeve sets up internal shield layer, external shielding layer in the pouring body, the internal shield layer includes cylinder copper shield net, and 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 external shielding layer includes the electrically conductive nylon body of ring form, and the ring is covered with the round hole on describing the electrically conductive nylon body, electrically conducts along the ring form and external week of nylon draws forth four fixing bolt linking arms, sets up fixing bolt in the fixing bolt linking arm. The utility model discloses rational in infrastructure, the working property is good.
Description
Technical field
This utility model relates to a kind of Novel shielding bus casing.
Background technology
Switch cubicle bus casing in the past, the rectangular cross section structure of internal high pressure busbar causes internal electric field skewness, and there is the tip of cabinet outside, is easily generated point discharge.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, the Novel shielding bus casing of favorable working performance.
Technical solution of the present utility model is:
A kind of Novel shielding bus casing, including pour mass, pour mass arranges internal shield, external shielding layer, it is characterized in that: described internal shield includes cylindrical shape copper shield net, 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 protruding from gauze screen net wall, and annulus itself 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；
Described external shielding layer includes circular electroconductive nylon body, and circular electroconductive nylon body is covered with circular hole, draws four fixing bolt linking arms along circular electroconductive nylon external week, arranges fixing bolt in fixing bolt linking arm.
This utility model is rational in infrastructure, and inner shield maskable copper bar is most advanced and sophisticated, uniform inner electric field；External shield masks the tip of cabinet, is the Electric Field Distribution between cylinder and annulus between interior external shield, is distributed for uniform electric field, thus reduces the purpose of shelf depreciation, it is ensured that product safe operation during life-time service.Owing to inner shield body uses copper material, resistance is less；The specific shape and structure of this utility model, Electric Field Distribution is uniform, and actually high-pressure side becomes an equipotential high-voltage charged 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.
Fig. 2 is internal shield structural representation.
Fig. 3 is external shielding layer structural representation.
Detailed description of the invention
A kind of Novel shielding bus casing, including pour mass 1, pour mass arranges internal shield 2, external shielding layer 3, described internal shield includes cylindrical shape copper shield net 4, 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 5 protruding from gauze screen net wall, and annulus itself by copper shield net volume around forming；The lead-out wire 6 being connected with cylindrical shape copper shield net uses threaded insert or soft whipping wire；
Described external shielding layer includes circular electroconductive nylon body 7, it is covered with circular hole on circular electroconductive nylon body, draw tetra-fixing bolt linking arms of four fixing bolt linking arm 8(along circular electroconductive nylon external week to be uniformly distributed along circular electroconductive nylon external week), fixing bolt linking arm arranges fixing bolt 9.
