Description

Bushing shell for transformer conducting rod fastener
Technical field
The utility model relates to a kind of power accessories, particularly relates to a kind of bushing shell for transformer conducting rod fastener, and the power transformer bushing being applicable to 66kV grade connects in conducting rod installment work, belongs to electric power application.
Background technology
At present, in electric power transformer oil paper capacitor formula sleeve pipe installation process, when the conducting rod of drawing is installed on sleeve pipe top, laterally having a diameter 8mm drift bolt to insert, is accidents caused in order to prevent from conducting rod from getting loose being slipped in transformer.But when practice of construction, often drift bolt jack dislocation after conducting rod connection screws, drift bolt cannot be inserted, conducting rod spiral shell button can only be adjusted back, conducting rod is caused to be connected with external conductive member not tight, transformer finds that when doing periodic inspection and detecting D.C. resistance becomes gradually and exceeds standard greatly, forming device safe operation hidden danger.Therefore conducting rod connects the untight problems demand solution of external conductive member.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of bushing shell for transformer conducting rod fastener, solves conducting rod in prior art and is connected untight problem with external conductive member.
The technical solution of the utility model is as follows:
Comprise disc spring film and metal mat; Disc spring film is axially tapered, and disc spring film truncation surface is trapezoidal, and disc spring film is set to two, the round table surface of two disc spring films is oppositely arranged formation X-shaped, metal mat is annular, and annular metal mat is arranged between two disc spring films, and metal mat truncation surface is rectangle.
Described disc spring film is of a size of, internal diameter 15mm, external diameter 30mm, depression angle 10 o.
Described metal mat is of a size of, internal diameter 15mm, external diameter 30mm, thickness 3mm.
The utility model has the advantages of as follows:
1, two disc spring films become X-shaped, between metal mat is arranged on, utilizes the elastic force squeezing action of disc spring film to screw conducting rod, ensure that conducting rod and the compact siro spinning technology being connected external member, detect D.C. resistance and reach equipment operation use standard.
2, verify through lot of experiments, disc spring film and metal mat are set to above-mentioned size, the two fiting effect is best, elastic force extruding is the most desirable, connect tightr, ensure that the safe operation of power transformer, shorten the transformer interruption maintenance time, in power industry, have promotional value very widely.
3, do not change former modular construction, volume is little, lightweight, easy and simple to handle, quick, and a people can operate, and without the need to hoisting equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Application Example structural representation of the present utility model.
In figure, 1, disc spring film, 2, metal mat.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, concrete structure of the present utility model is described in detail.
Embodiment
As shown in Figure 1-2, disc spring film 1 and metal mat 2 is comprised; Disc spring film is axially tapered, and disc spring film truncation surface is trapezoidal, and disc spring film is set to two, the round table surface of two disc spring films is oppositely arranged formation X-shaped, metal mat is annular, and annular metal mat is arranged between two disc spring films, and metal mat truncation surface is rectangle.
Described disc spring film is of a size of, internal diameter 15mm, external diameter 30mm, depression angle 10 o.
Described metal mat is of a size of, internal diameter 15mm, external diameter 30mm, thickness 3mm.
During the utility model test, effectively solve 66kV grade 31500kVA transformer high-voltage bushing and connect not tight, D.C. resistance becomes large excessive problem gradually.Easy and simple to handle in using, time saving and energy saving, obtain the consistent favorable comment of operating personnel.
During use, the utility model is inserted conducting rod end, when spiral shell button screws and adjusts back some, due to the elastic force squeezing action of butterfly spring sheet, ensure that conducting rod and the compact siro spinning technology being connected external member, detect D.C. resistance and reach equipment operation use standard.
