Abstract
The invention provides an axial separating type ultra high voltage shielding cover, relating to the improvement of an ultra high voltage shielding cover structure in power equipment. While ensuring product structure and precision, processing is convenient, a production period is short, and processing cost is low. A shielding cover body shows a circular ring shape, and a cross section shows a C shape. The body is formed by and combination welding of a pair of circular ring shaped left half body and right half body with a cross section of a C shape. A soldering joint is positioned at a body diameter line position. According to the invention, a structure of the ultra high voltage shielding cover is changed into a form of an upper half and a lower half which are welded into one body at a middle position, and followed by polishing processing and welding. According to the above structure form, a complex degree of mould manufacture can be reduced (only stamping forming, left and right combination welding and edge flanging are needed), efficiency can be raised simultaneously, production cost is reduced to one third of overall spinning. When carrying out small amount processing especially, since the amount is not very large, and if an operation mould is invested, the cost of a single product is extremely high. According to the invention, the processing cost of the product is reduced substantially.
Description
Technical field
The present invention relates to improvement to superhigh pressure shielding case structure in the power equipment.
Background technology
When the power equipment charging test,, need radome be set in correlation test instrument, device external for preventing the influence of high voltage electric field to test apparatus, equipment.The power test equipment of different structure shape needs the adaptive radome of profile with it; Such as; Be applied in the instrument transformer of the annular in the superhigh pressure test, its outside radome one is the requirement that needs to adapt to the superhigh pressure occasion, the 2nd, and its structure can be suitable with instrument transformer.The superhigh pressure radome is the vitals of voltage transformer in the high-voltage fence, and the superhigh pressure radome is different from general radome, and the industrial frequency withstand voltage that it bears requires than higher, and manufacturing process is relatively stricter, and particularly the radome curved surface requires to be lower than the 5pc discharge capacity.
At present, being applied in the outside ring shielding cover of instrument transformer all is global formation usually, and the radome body is circular, the c-shaped shape in cross section, and opening is in the inner ring inboard.But the Mold Making more complicated of global formation, the demoulding is inconvenient, and production efficiency is low, and production cost is high.
Summary of the invention
The present invention is directed to above problem, the axially section fraction superhigh pressure radome that provide a kind of when guaranteeing the product structure precision, easy to process, with short production cycle, processing cost is low.
Technical scheme of the present invention is: said radome body is circular, and the c-shaped shape in cross section, said body are by a pair of semi-annular shape that is, and the cross section is a left side half body and involutory being welded of right half body of C shape; Said soldered is positioned at said body diameter line position.
Said cross section be the opening of C shape body towards the axle center of body, and said opening peristoma is turned in the shape chamber of C shape body.
The present invention changes the structure of superhigh pressure radome into upper and lower two halves form, and welding is connected as a single entity in the centre; Then, the processing welding lines of polishing again.This version not only can reduce the complexity (only needing the involutory welding in punch forming+left and right sides, peristoma flange) that mould is made; Simultaneously can also improve the efficient of work; Make production cost be reduced to about 1/3rd of whole spinning, reached same effect, satisfied user's demand.Particularly add man-hour, because amount is not too big in small lot; If carry out the mould input, can cause the cost of single product high.The present invention greatly reduces the processing cost of product.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is an A-A cutaway view among Fig. 1
1 is left half body among the figure, the 2nd, and steel wire thread bush, the 3rd, Connection Block, the 4th, soldered, the 5th, right half body, the 10th, peristoma, the 11st, smallest circle contour.
Embodiment
The present invention is like Fig. 1, shown in 2, and said radome body is circular, and the c-shaped shape in cross section, said body are by a pair of semi-annular shape that is, and the cross section is a left side half body 1 and right half body, 5 involutory being welded of C shape; Said soldered 4 is positioned at said body diameter line (being positioned on the plane perpendicular to horizontal plane through axial line) position.
Said cross section be the opening of C shape body towards the axle center of body, and said opening peristoma 10 is turned in the shape chamber of C shape body.Make the diameter of peristoma 10 less than the minimum diameter line 11 of body 1.
Product also need be provided with parts such as steel wire thread bush 2, Connection Block 3 in manufacturing process.
Claims (2)
1. one kind is axially cut fraction superhigh pressure radome, and said radome body is circular, and the c-shaped shape in cross section is characterized in that, said body is by a pair of semi-annular shape that is, and the cross section is a left side half body and involutory being welded of right half body of C shape; Said soldered is positioned at said body diameter line position.
2. a kind of axial section fraction superhigh pressure radome according to claim 1 is characterized in that, said cross section be the opening of C shape body towards the axle center of body, and said opening peristoma is turned in the shape chamber of C shape body.
