Description
Technical field
The present invention relates to the manufacture of epoxy cast transformer, and in particular to a kind of tap protective cover of cast transformer and its
Installation method.
Background technology
Conventional epoxy casting distribution transformer high-voltage tap scope is ± 2X2.5%, i.e., 5 grade, thus transformer has 6
Tap A1~A6.This 6 taps are 6 binding posts of round estrade, and the connection between binding post is converted with connection sheet, are realized
The adjustment of tapping range.This 6 binding posts of round estrade all expose in atmosphere, easy productive set dust.
In atmosphere, easy oxidation and rusting, causes loose contact, contact resistance after making moist for binding post and its connection sheet exposure
Increase, produces resistance loss when high current passes through, produce heat, in the course of time, heat transfer to neighbouring encapsulating epoxy resin,
The ageing process of resin can be accelerated, the insulation life of transformer is influenceed, finally terminate life of product.
Dust of the productive set on tap, is pollution that air is caused, and productive set is excessive, can tree under high electric field effect
The shelf depreciation on fat surface, corrodes insulation resin, similarly influences the insulation life of transformer, causes insulation degradation, accelerates ring
The ageing process of oxygen tree fat, accelerates the damage process of resin, and safe operation is constituted a threat to.
Therefore, tap has been protected, has made its not moisture-sensitive oxidation and rusting, reduced shelf depreciation caused by dust productive set, prevented
Gradually, the normal operation to epoxy cast transformer extends product service life to micro- Du, is good.
Therefore, transformer manufacturing station-service plexiglass tent, 6 taps are covered.Then, in 6 tap A1~A6
Outside, it is further added by two nuts for fixing plexiglass tent, the ring of the embedding high-voltage connection panel being cast near tap
In oxygen tree fat, so it is necessary to be drilled on the mould of patch panel, to install the two embedding cast nuts, the result is that not
Patch panel mould, and the seepage resin when the place of embedding cast nut is susceptible to cast are only damaged, pour mass is possible to
Cavitation bubbles are produced, the quality of whole pour mass is influenceed.Particularly, oneself is used in thousands of cast transformers of operation
This method installs this plexiglass tent to increase, and is just more difficult to accomplish.
The content of the invention
The present invention a kind of the tap protective cover and its installation method of cast transformer, can not only be used in the cast newly dispatched from the factory and become
On depressor, not installing on the old product for tapping protective cover in binding post arrangement same distance, and old product equally can be also used
Pour mass need not make any a bit variation.
One of technical solution of the present invention：
A kind of tap protective cover of cast transformer, including plexiglass tent, nylon bolt and rubbery stopper, plexiglass tent are adopted
With transparent configuration, plexiglass tent front be provided with the equal number of circular hole of binding post and rubbery stopper on circular hole and
The nylon bolt being connected with circular hole, the position of circular hole is corresponding with binding post, and the diameter of circular hole is than adaptation on binding post
The big 2mm of the diameter of bolt.
Further, described rubbery stopper is convex, and microcephaly is the cylinder of diameter 0.5mm bigger than circular hole, and major part is straight
The cylinder of footpath 4~6mm bigger than circular hole.
Further, nylon bolt has a pair, and a pair of nylon bolts are arranged on the diagonal circular hole of plexiglass tent, diagonally
Line circular hole is divided into diagonal with end in the middle of the diagonal sum of two ends.
The two of technical solution of the present invention：
The installation method of the tap protective cover of a kind of cast transformer, with being provided with and binding post same number and corresponding circular hole
Plexiglass tent, cover the individual round estrade binding post in the patch panel of high-tension coil epoxy casting body, and with two nylon
Be fixed on plexiglass tent on binding post by bolt.
Further, the position that described plexiglass tent installs nylon bolt has three kinds；
The first is that nylon bolt connects installed in A1 and A6 when binding post will use tri- kinds of connections of A2-A3, A3-A4, A4-A5
On terminal；
Second is that nylon bolt is arranged on A3 and A6 binding posts when binding post will use two kinds of connections of A1-A2 or A4-A5
On；
The third is that nylon bolt is arranged on A1 and A4 binding posts when binding post will use two kinds of connections of A5-A6 or A2-A3
On.
Further, the installation method of described plexiglass tent, other circular holes to not installing nylon bolt install rubber
Stopper.
The present invention use this borehole structure corresponding with binding post same number and position, not only overall dimensions minimum,
Material saving, cost declining, and suitable for the old and new's whole cast transformer of binding post same distance, without changing epoxy casting body
Hair and cast patch panel mould, can realize immediately.
