Abstract
The utility model relates to an equalizer cover on the test device in the electroengineering field, the equalizer cover is characterized in that fixing stainless steel tubes are arranged orderly on the outer surface of a frame. Compared with the existing equalizer covers or loops, the surface strength is improved, uneven phenomenon and oxidation phenomenon are not easy to occur, the quality of integral equalizer cover is improved, and the requirement for the surface finish quality in text is satisfied. The utility model with simple structure and easy production can reduce the waste of the mould expense, increase the economic benefit of enterprise and replace the existing equalizer covers or loops.
Description
Technical field
The utility model relates to the parts in a kind of test unit of electrical technology field, relates in particular to a kind of grading shield.
Background technology
In a kind of device when power equipment and testing equipment carry out withstand voltage, no partial discharge test grading shield is arranged, perhaps be called grading ring.Existing grading shield or ring, its structure mainly is made of the circle and the shape metallic object of skeleton and the skeleton regular setting in outside, these circles and shape metallic object adopt rolled lead to beat and form, therefore the grading shield of each specification all needs mould, the waste of manufacturing enterprise's die cost is very big, and finished product is in carrying, dismounting, be easy in the installation process cause uneven and cut, it is long or through the place of corrosion is arranged that the stereotype sanding washes down back time one, its surface sand hole occurs because of easy oxidation, the appearance of these situations all can have a strong impact on test, and manufacturing enterprise and applying unit are brought unnecessary loss.
Summary of the invention
The purpose of this utility model provides a kind of intensity height, not yielding at existing grading shield or ring above shortcomings, is difficult for the grading shield of oxidation.
The purpose of this utility model is achieved through the following technical solutions, and a kind of grading shield that comprises skeleton is characterized in that the outside surface of skeleton is arranged fixedly stainless-steel tube in order.
The utility model utilizes stainless-steel tube easily to bend and indeformable characteristics, pass through related process, it is bent into meets the requirement of skeleton outside surface figure curvature, and it is fixing in order, improve intensity, be not prone to uneven phenomenon, and be difficult for oxidation again, improved total quality, can satisfy in the test requirement again its surface smoothness.The utility model is simple in structure, easily makes, and has significantly reduced the waste of die cost, has improved economic benefit of enterprises, alternative existing grading shield or ring.
The end of stainless-steel tube is sealed through plug, and skeleton also adopts stainless steel material to make.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a stainless-steel tube end construction synoptic diagram in the utility model.
Among the figure, the 1st, skeleton, the 2nd, stainless-steel tube, the 3rd, plug.
Embodiment
The utility model is made of skeleton 1 and stainless-steel tube 2, and stainless-steel tube 2 bends according to skeleton 1 outside surface figure curvature, and arranges in order and fix, and the end of stainless-steel tube 2 is through plug 3 sealings, and skeleton 1 also adopts stainless steel to make.
Claims (3)
1, a kind of grading shield that comprises skeleton is characterized in that the outside surface of skeleton is arranged fixedly stainless-steel tube in order.
2, grading shield according to claim 1 is characterized in that the end of stainless-steel tube is sealed through plug.
3, grading shield according to claim 1 is characterized in that skeleton also adopts stainless steel to make.
