Abstract
The invention discloses a combined cross-over block of a dry-type transformer. The combined cross-over block is cuboid, and is characterized by comprising a top plate and a base, wherein the top plate is spliced together with the base; or at least one core piece is arranged between the top plate and the base. The problems of increase in the die cost and long production period caused by the need of a large quantity of blocks of different specifications due to production specification change of the cross-over block in the prior art are solved. The combined cross-over block is convenient to combine, meets the requirements of products of different specifications on cross-over blocks of different sizes, and contributes to effectively reducing die cost and shortening the production period.
Description
Technical field
The present invention relates to a kind of cross-over block of transformer, particularly relate to a kind of combined insulation cushion block of dry-type transformer.
Background technology
Especially during the outlet of end, electric field strength is higher for the end winding of transformer.The distance of gripping to iron is that coil-span is from 2-3 times.Basic end insulating part is core insulation.Usually in the Main Insulation Structure of Electric of dry-type transformer, upper yoke insulation and lower yoke insulation form by cross-over block.This cross-over block strengthens BMC by the unsaturated-resin glass fibre to be made, and it is shaped as cuboid collets, leans on an end at iron yoke place that one oblique angle is arranged, and is suitable for O shaped iron core structure, is placed on coil herein inboard by iron yoke position.Collets are distributed in the both sides of transformer coil upper end and the both sides of lower end.The collets operated by rotary motion is at the dry-type transformer body two ends, as the part of main insulation.Be that every phase coil has up and down four cushion blocks evenly to place.The thickness of cushion block is to be determined by the electric pressure of transformer and capacity.Voltage raises or capacity strengthens, and pad thickness is corresponding to be increased, the corresponding increasing of volume.The insulation costs of transformer accounts for whole transformer cost significant proportion.It is high that existing dry-type transformer has a relative cost, the problem that electric strength is low.
For solving the problems of the technologies described above, the ZL200620148079.3 utility model patent discloses a kind of umbrella shape cross-over block of dry-type transformer, this umbrella shape cross-over block is the cuboid collets that an oblique angle is arranged by iron yoke end, and its special feature is to be shaped with the equal-sized groove of multiple tracks along short transverse around the collets side.It is in order to be suitable for the installation of O shaped iron core structure that cushion block is provided with the oblique angle by iron yoke end.Between the groove at place, cushion block oblique angle and groove, all stagger.The introducing of groove has significantly strengthened over the ground creepage distance of coil, has greatly strengthened the anti-short circuit capability of its electric strength and transformer.Its do not increase the height prerequisite under and strengthen the electric strength of himself, namely strengthen coil creepage distance over the ground.Yet this umbrella shape cross-over block is overall structure, is to be formed by fixed mould hot pressing, because the dimensions of transformer is different, the size of required cushion block different (length and thickness all change) needs a large amount of moulds during making, and die cost is more.Particularly the product required size of special transformer (length all changes with thickness) is different, must make different pad moulds according to the order requirements size, and fabrication cycle is longer.Therefore, a kind of cross-over block that can save production mould, minimizing fabrication cycle becomes the target that those skilled in the art pursue.
Summary of the invention
The object of the invention is to solve cross-over block of the prior art and change the cushion block that needs a large amount of different sizes because of product specification, produce thus the problem that die cost increases, the production cycle is long.
For solving the problems of the technologies described above, the present invention is by cross-over block being designed to a cover Combined bearing block, by different compound modes to satisfy the needs of products of different specifications.Thereby can save in a large number die cost, and shorten widely fabrication cycle.
The combined insulation cushion block of a kind of dry-type transformer of the present invention, described combined insulation cushion block is rectangular-shaped, it is characterized in that, and this combined insulation cushion block comprises a top board and a pedestal, and described top board and pedestal are plugged in together.
As preferably, the bottom surface of described top board has recessed seam, has above the described pedestal to cooperate the male half coupling of pegging graft with the recessed seam of described top board.Described pedestal and top board are plugged in together at an easy rate by the convex-concave seam, also separating and making up again at an easy rate.
In order to have strengthened over the ground creepage distance of coil, the side is provided with annular groove along short transverse around described cross-over block by top board and base combination.
As preferably, upper along having respectively the chamfering that the cross section is the concave arc shape around the lower edge all around of described top board side and the described pedestal, form described annular groove at the faying face place of cross-over block behind described top board and the described pedestal fastening.Annular groove is located on the faying face of top board and pedestal, is conducive to mold releasability.
The present invention also provides a kind of combined insulation cushion block of dry-type transformer, described combined insulation cushion block is rectangular-shaped, it is characterized in that, this combined insulation cushion block comprises a top board, at least one chipware and a pedestal, and described top board, at least one chipware and pedestal are plugged in together.
As preferably, the bottom surface of described top board has recessed seam, has male half coupling above the described pedestal, described chipware top and below be respectively equipped with male half coupling and recessed seam; The top male half coupling of described chipware cooperates with the recessed seam of described top board or another described chipware, and the following recessed seam of described chipware cooperates with the male half coupling of described pedestal or another chipware.Adopting the convex-concave seam to peg graft between top board, chipware, the pedestal conveniently makes up and splits.
In order to have strengthened over the ground creepage distance of coil, the side is provided with at least two annular grooves along short transverse around described cross-over block by a top board, at least one chipware, a base combination.
As preferably, lower to having the chamfering that the cross section is the concave arc shape around the described top board side, around the described chipware on the side edge and lower edge have respectively the chamfering that the cross section is the concave arc shape, upper along having the chamfering that the cross section is the concave arc shape around the described pedestal, described top board, chipware, pedestal form described annular groove at the faying face place after fastening.Annular groove is located at the faying face place between two, is beneficial to mold releasability.
As preferably, the circumferential lateral surface between two upper and lower concave arc shape chamferings of described chipware forms a bulge loop.
As preferably, the side is provided with at least two annular grooves along short transverse around the described chipware, and is a bulge loop between the described adjacent annular groove; Circumferential lateral surface between upper and lower two concave arc shape chamferings of described chipware and the adjacent described annular groove forms two bulge loops.
Select the suitable adjustment of the chipware cross-over block height of a bulge loop more flexible, convenient, select the chipware of 3 bulge loops to be suitable for higher cross-over block.
As preferably, the top board of described cross-over block, pedestal and chipware be shaped as Long Circle or ellipse.The both sides of cross-over block are semicircle, make it rounder and more smooth, avoid the appearance of wedge angle, have improved electric property; Can make Mold Making relatively simple, and elegant in appearance.
