Description

A kind of transformer binding post header structure

Technical field

The utility model relates to power transformer technical field, particularly relates to a kind of transformer binding post header structure.

Background technology

In recent years along with the collection of national grid rural power grids, city net changes, the demand of transformer is increasing, and be all mostly capacity at 630kVA and following distribution transformer, also more and more higher to the requirement of producer's mass production.The transformer of centralized purchasing is not immediately installed, and is all in the warehouse being put into various places national grid and is mostly outdoor and puts, and binding post is not well protected, and exposes to the sun and rain.The binding post contacted with air usually there will be the phenomenon of oxidizing blackening, and how long outward appearance will not become unsightly.

Utility model content

For prior art Problems existing, the purpose of this utility model is to provide a kind of transformer binding post header structure, pairs of posts can realize good protection.

To achieve these goals; the utility model provides a kind of transformer binding post header structure; comprise porcelain vase, binding post and protective cover; binding post is fixed on porcelain vase by nut; protective cover inner chamber coordinates with binding post size; protective cover is sleeved on binding post and nut is outside, and protective cover and binding post adopt matched in clearance and fit clearance is 0.8-1.2mm, and protective cover is adopted made of plastic.

Preferably, the fit clearance of protective cover and binding post is 1mm.

Compared with prior art, overall dimension size according to binding post and clamp nut devises protective cover, protective cover and binding post, nut adopts gap to be the tight fit of 0.8-1.2mm, can prevent protective cover from causing dropping because transporting vibrations, the collision of its thing and binding post can also be prevented, by protective cover, the binding post of transformer and nut are wrapped up together, avoid binding post and nut exposes to the sun and rain, decrease the above-mentioned oxidation that both carry out with air, make the binding post before installing just with before dispatching from the factory, brand-new as one, thus pairs of posts shields.

Accompanying drawing explanation

Fig. 1 is the utility model transformer binding post header structure structural representation.

Embodiment

The purpose of this utility model is to provide a kind of transformer binding post header structure, can reduce the waste of material and install succinctly, conveniently.

The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection range of the present utility model.

Please refer to Fig. 1; in one embodiment; transformer binding post header structure provided by the utility model; comprise porcelain vase 3, binding post 2 and protective cover 1; binding post 2 is fixed on porcelain vase 3 by nut, and protective cover 1 inner chamber coordinates with binding post 2 size, and protective cover 1 is sleeved on binding post 2 and nut is outside; protective cover 1 and binding post 2 adopt matched in clearance and fit clearance is 1mm, and protective cover 1 is adopted made of plastic.

Above-mentioned transformer binding post header structure, overall dimension size according to binding post 2 and clamp nut devises protective cover 1, protective cover 1 and binding post 2, nut adopts gap to be the tight fit of 0.8-1.2mm, can prevent protective cover 1 from causing dropping because transporting vibrations, the collision of its thing and binding post 2 can also be prevented, by protective cover 1, the binding post 2 of transformer and nut are wrapped up together, avoid binding post 2 and nut exposes to the sun and rain, decrease the above-mentioned oxidation that both carry out with air, make the binding post 2 before installing just with before dispatching from the factory, brand-new as one, thus pairs of posts 2 shields.

It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise which key element, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising key element and also there is other identical element.

Apply specific case herein to set forth principle of the present utility model and execution mode, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection scope of the present invention.
