Abstract

The utility model provides a transformer lead fixing structure, which comprises a lead. A paper board wraps a fixed section of the lead; a heat-shrinkage polyester tube is bond outside the paper board; and the lead is fixedly bond with a wood piece through the heat-shrinkage polyester tube. The transformer lead fixing structure is simple and compact, obvious in using effect, high in binding strength and good in fixing performance, and the lead is fixed through the heat-shrinkage polyester tube on the premise of not changing a lead structure; and moreover, the fixing structure is small in structural size, the size of an oil tank of a transformer is reduced, and the quantity of transformer oil is reduced, therefore, an effect of reducing the cost is achieved.

Description

The transformer lead fixed structure

Technical field

The utility model belongs to the transformer technology field, is specifically related to a kind of structure that is used for fixing transformer lead.

Background technology

Transformer is when assembling, and the outside of transformer generally need fixed and be drawn out to every group of lead-in wire with support.For the root that guarantees transformer lead is not pullled or bending, marshalling, the wood clamp spare that needs usually to adopt electrician's timber to make is fixed lead-in wire.Traditional transformer lead-in wire fixed method is to clamp lead-in wire 103 through two wooden parts 101,102, and fixing through bakelite bolt and bakelite nut 104, wears the bakelite bolt in the middle of promptly, and both sides are fastening with the bakelite nut, and are as shown in Figure 1.This fixed form can cause the oversize of fixed structure, thereby has strengthened the fuel tank size of transformer, has increased the consumption of transformer oil.

The utility model content

To the problems referred to above, the applicant improves through research, and another kind of transformer lead fixed structure is provided, and adopts this structure colligation lead-in wire, not only saves the fuel tank space, and can obtain the fixed effect more better than traditional approach.

The technical scheme of the utility model is following:

A kind of transformer lead fixed structure comprises lead-in wire, and the canned paragraph of said lead-in wire is wrapped with cardboard, and said cardboard is banded with thermal contraction terylene pipe outward, and lead-in wire is fixed through the colligation of said thermal contraction terylene Guan Yumu spare.

The useful technique effect of the utility model is:

The utility model is simple in structure, compact, and result of use is obvious, under the prerequisite that does not change pin configuration, adopts thermal contraction terylene pipe anchor leg, and colligation intensity is high, and fixed performance is good.And physical dimension is small and exquisite, has reduced the fuel tank size of transformer, has reduced the consumption of transformer oil, thereby plays the effect that reduces cost.

Description of drawings

Fig. 1 is the sketch map of existing transformer lead fixed structure.

Fig. 2 is the structural representation of the utility model.

Embodiment

Further specify below in conjunction with the embodiment of accompanying drawing the utility model.

As shown in Figure 2; The transformer lead fixed structure of the utility model comprises lead-in wire 1, and the canned paragraph of lead-in wire 1 is wrapped with cardboard 2 (like brown paper); The outer thermal contraction terylene pipes 3 that are banded with of cardboard 2, lead-in wire 1 are fixed through thermal contraction terylene pipe 3 and wooden part 4 colligations.

Thermal contraction terylene pipe in the utility model is to prolong same direction by high-strength hot contraction terylene fiber to work out, in a tubular form.Prolong these characteristics of same direction just and make thermal contraction terylene pipe have high-intensity shrinkage, use its colligation lead-in wire, can obtain the effect more better than traditional approach.

For example, be example with SZ11-40000/110 (the long 4.3m of fuel tank, high 2.6m) transformer, use the fixed structure of the utility model, can practice thrift transformer oil: (50-4) * 4.3*2*2.6*0.9=925.7kg.With 11 yuans of calculating of every kilogram of transformer oil, can practice thrift RMB: 925.7*11=10182.7 unit.

Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection range of the utility model.

Claims

1. transformer lead fixed structure; It is characterized in that: comprise lead-in wire (1); The canned paragraph of said lead-in wire (1) is wrapped with cardboard (2); The outer thermal contraction terylene pipe (3) that is banded with of said cardboard (2), lead-in wire (1) is fixed through said thermal contraction terylene pipe (3) and wooden part (4) colligation.
