Description
Technical field
The utility model belongs to electric field, is related to a kind of bracket composite post insulator.
Background technique
Power circuit is 33KV, divides A, B, C three-phase line, is distributed in oblique triangle formula, A, C phase in same level, away from
From farther out, B phase in the top of C phase, BC two-phase apart from relative close, when bigger birds B, C phase open wing stop or
When taking off, it will result in B phase and the short circuit of C phase and cause to have a power failure and trip, both destroy ecological environment, can also be caused because of having a power failure to stop production
Larger economic loss.
Utility model content
(1) purpose of utility model
The purpose of the utility model is to provide a kind of bracket composite post insulators, solve flying bird and cause line short
Problem.
(2) technical solution
In order to solve the above-mentioned technical problem, the utility model provides a kind of bracket composite post insulator, which is characterized in that
Mainly it is made of glass-epoxy leading-drawing rod 6, silicon rubber umbrella skirt 7, bracket 1 and supporting insulator base 4；
Supporting insulator base 4 is fixedly connected with the top of bracket 1；Glass-epoxy leading-drawing rod 6 is fixed on branch
On column insulator foot 4, glass-epoxy leading-drawing rod 6 is equipped with multiple silicon rubber umbrella skirts 7, glass-epoxy
Anti- vortex cable clamp 8 is fixed at the top of leading-drawing rod 6.
(3) beneficial effect
The utility model is covered at the top of line bar by increasing by one " support rack type composite post insulator ", and will be original oblique
Three-legged structure is changed to positive triangle structure, increases between B phase and A, C phase, especially the spacing between B phase and C phase and climb electricity away from
From thoroughly solving the problems, such as that flying bird causes line short, make relatively easy, facilitate construction, remarkable in economical benefits.

Specific embodiment
It is with reference to the accompanying drawings and examples, practical to this to keep the purpose of this utility model, content and advantage clearer
Novel specific embodiment is described in further detail.
The utility model provides a kind of bracket composite post insulator, mainly by glass-epoxy leading-drawing rod 6, silicon
Rubber full skirt 7, bracket 1 and supporting insulator base 4 are constituted；
In Fig. 1, bracket 1 is special special-shaped bracket, is formed by four columns and the support being fixed at the top of column fixation；
Column is sheet, is secured the stand in electric pole top with 8 connection bolts 2, the branch of supporting insulator base 4 and bracket 1
Seat is linked together with 4 supporting insulator base connection bolts 5；
Glass-epoxy leading-drawing rod 6 is fixed on supporting insulator base 4, glass-epoxy leading-drawing rod
It is cased with multiple silicon rubber umbrella skirts 7 on 6, anti-vortex cable clamp 8 is fixed at the top of glass-epoxy leading-drawing rod 6；
When setting up cable 10 (steel-cored aluminium strand), cable is fixed on anti-vortex cable clamp 8 by 2 cable clip bolts 9
It is interior；Wherein supporting insulator base 4 is welded together with glass-epoxy leading-drawing rod 6 by high-intensitive wlding.
Since utility model is on 33KV route, cable is 120/20sq mm steel-cored aluminium strand, so we are in product
It is strict in terms of stress intensity and high voltage performance.In terms of intensity, 6 tension of glass-epoxy leading-drawing rod and
Flexural strength is 2 times higher than common iron, is 8~10 times of high strength china material, can receiving >=20KN yield stress；Resistance to
In terms of high pressure, I takes into account the humidity of use environment and pollution level, and electrostrictive coefficient is climbed in increase, i.e., silicon rubber umbrella skirt 7 has
Effect height increases, and increases insulation arc extinction performance.Through stress test and pressure test, the complete composite design requirement of product.
When setting up cable, 3 the utility model bracket composite post insulators are fixed on electric pole top in equilateral triangle
Portion, A, B, C threephase cable pass therethrough respectively, form positive triangle structure, change original oblique three-legged structure, and B and C
Line spacing increases 4 meters (cross-arm B are only had 600mm or so at a distance from cross-arm) by original 1.6 meters, is effectively prevented
The problem of causing short circuit to power off due to fortuitous events such as flying birds.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
