Description
Technical field
The utility model discussion be oil-impregnated paper condenser type transformer bushing.
Background technology
At present, market sell with the matching used oil-impregnated paper condenser type transformer bushing of transformer, usually by conservator, contact tube, capacitor core, last insulator, spacer flanger, following insulator, compositions such as base, contact tube and capacitor core have been formed the internal structure of sleeve pipe, and following insulator, flange, last insulator, conservator has been formed the appearance part of sleeve pipe, because each coefficient of expansion difference partly, usually between conservator and contact tube, add a copper elastic plate, through compressing the sealing that the triangle rubber guarantees elastic plate and contact tube, and must rotate during compression triangle rubber, the easy transfer of triangle rubber and tearing destroys sealing.Base sealing means partly is to twine raw material band on contact tube, and the time one is long, and the raw material band that twines on the contact tube at high temperature easily lost efficacy, and transformer oil is had pollution.More than the seepage that causes of any mode, rainwater just may enter transformer along the contact tube inwall, causes accident to take place.
Summary of the invention
The technical problems to be solved in the utility model is to overcome each parts of prior art middle sleeve because of coefficient of expansion difference and the bad deficiency of seal member sealing effectiveness, and a kind of a kind of oil-impregnated paper condenser type transformer bushing of simple in structure, good seal performance is provided.
A kind of oil-impregnated paper condenser type transformer bushing of the utility model is improvements over the prior art, and the top and the bottom part of bushing is done adaptive improvement, and seal member made improvements solves above-mentioned technical problem.It comprises: binding post 1, conductive head 2, pigtail splice 3, contact tube 6, conservator 4, insulator 9 and 11, flange 10, base 14, voltage equalizing ball 12 up and down, it is characterized in that: also comprise conservator cover plate 8, conservator cover plate 8 is enclosed within outside the contact tube 6 and conservator 4 is fixed, conductive head 2 one ends are connected with binding post 1, the other end and conservator cover plate 8 are fixing, pigtail splice 3 is connected with conductive head 2, and contact tube 6 is enclosed within outside the pigtail splice 3, and cable 5 is fixing with pigtail splice 3; Base 14 is T types, and it passes contact tube 6 from the below of following insulator 11, is threaded with contact tube 6, and base 14 has a bleeder plug 13 with the inboard of following insulator contact-making surface, and voltage equalizing ball 12 openings upwards are enclosed within outside the base 14, are threaded with base 14.
Above-mentioned conservator cover plate 8 has two road sealing grooves with contact tube 6 junctions, and above-mentioned base 14 has two road sealing grooves with contact tube 6 junctions.Following insulator 11 adopts glass fibre reinforced plastic cylinder.
A kind of oil-impregnated paper condenser type transformer bushing of the utility model will have the top and the bottom part of sleeve pipe now and do some adaptive improvement, increase the conservator cover plate at head, replaced rain cover, adopted a kind of base of thickening in the bottom, and reach and the sealing partly of the polished rod of contact tube with the increase sealing ring, it is non-leakage that evidence just can be born the 0.5mpa gas pressure test with one sealing ring, can increase its reliability with two roads.For increasing mechanical strength and further improving electrical strength, following insulator can adopt glass fibre reinforced plastic cylinder.Above the base sealing ring, a bleeder plug is arranged, solved the problem of draining the oil of time insulator.Compare with prior art, the utlity model has easy and simple to handlely, safe, can improve the characteristics of piece electrical performance.
