Abstract
The utility model relates to a transformer used solid tube, in particular to a special transformer which is suitable for electric locomotive transformers, mining transformers, etc. The utility model comprises an insulating casing and a conductor, which is characterized in that the middle part of the conductor is covered with insulating material, and insulating resin is filled between the insulating material and the insulated casing for fixing as integration. The outer diameter side of the insulating coating can be also provided with a mounting flange according to the application requirements. The utility model has the advantages of shock resistance, hard burning, moisture resistance, easy maintenance, safe operation, good electric property, etc.
Description
The utility model belongs to transformer device, is conductor to be drawn pass the used a kind of solid bushing of shell, is applicable to transformer, especially special transformer such as locomotive transformator, mining transformer.
At present, the used sleeve pipe of transformer lead-out wire be adopt by the porcelain insulating overcoat with its in the middle part of be filled with insulating oil or gas or structure that insulating oil-insulating paper mix insulation etc. constitutes between the electric conductor that passes.Its weak point is: to the seal request strictness of cannula tip, particularly easily produce seepage and make moist and electric property declines that causes, easy firing etc. move unsafe factor and difficult in maintenance etc. when vibrating state; Simultaneously, the sleeve pipe volume is big, and overall mechanical strength is relatively poor.
The purpose of this utility model be to overcome the weak point in the above-mentioned prior art and provide that vibration resistance is better, nonflammable, moistureproof, easy to maintenance, security of operation, the less a kind of solid bushing of volume.
The purpose of this utility model can reach by following measure: it comprises insulating coating 1, electric conductor 4 etc., and its special character is: the middle part of electric conductor 4 is surrounded by insulating material 3, and and insulating coating 1 between be filled with insulating resin 2 and be fixed into one.
According to needs are installed, also can with resin 6 mucilage bindings mounting flange 5 be arranged at the outside diameter of the insulating coating in the utility model said structure 1.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the B-B cross-sectional view of Fig. 1;
See figures.1.and.2.Be surrounded by insulating material 3 at the middle part of electric conductor 4.Insulating material 3 can adopt polyester adhesive tape, glass fiber adhesive tape, insulating paper etc.Present embodiment insulating material 3 is to adopt insulating adhesive tape.Insulating coating 1 is enclosed within on the electric conductor 4 that is surrounded by insulating material 3, and fills insulating resin 2 betwixt and fix in aggregates.The used insulating resin 2 of present embodiment is an epoxy resin.Securing member etc. is equipped with at two ends at electric conductor 4.This solid bushing is applicable to the structure that is installed on the transformer case.
The utility model also can be in said structure has mounting flange 5 with resin 6 mucilage bindings on the external diameter of insulating coating 1.The resin 6 of present embodiment is to adopt epoxy resin.The solid bushing of this structure is applicable to the structure that flange is connected with transformer case.
The utility model adopts insulating resin 2 to be encapsulated in electric conductor 4 and insulating material 3 in the insulating coating 1 and forms holistic solid structure, has not only increased the bulk strength of sleeve pipe, has improved vibration strength, and does not have seepage and problem such as make moist.Therefore, compared with the prior art the utility model has advantages such as earthquake-proof function is good, nonflammable, moistureproof, easy to maintenance, security of operation, good electric property.Again because the electric property of insulating resin is better than gas, insulating oil, insulating paper etc., so volume of the present utility model can be done lessly.
Claims (3)
