Abstract
The utility model discloses a flame-proof type bushing of a transformer, which comprises an insulating porcelain sleeve and a bush; the insulating porcelain sleeve is internally provided with a conducting rod movably connected with the insulating porcelain sleeve; one end of the insulating porcelain sleeve is provided with annular rills; the bush is arranged between the insulating porcelain sleeve and the conducting rod; the other end of the insulating porcelain sleeve is provided with external threads. Compared with the prior art, the flame-proof type bushing has the advantages that the flame-proof type bushing comprises the insulating porcelain sleeve movably connected with the conducting rod, which can not only ensure the reliability of insulation, but also be conveniently taken down for welding a lead wire that is penetrated in the bushing; the half front part of the porcelain sleeve is made into gyrus shape so as to add creepage distance along the surface of an energized part and a grounded metal part.
Description
Technical field
The utility model relates to the electric connection technique of power industry field, the particularly technical field of flameproof dry-type transformer leading-out terminal.
Background technology
Usually the dry-type transformer lead-out wire all is to be fixed on the insulated terminal, not sealing between the device body of external connection line and transformer, when transformer body is installed in the housing of sealing, lead-out wire just can not adopt above-mentioned insulator structure, must adopt a kind of casing bit that had not only insulated but also lead-in wire can have been drawn, and adopts at one time conducting rod with the method for poured with epoxy resin in the middle of porcelain bushing, but because conducting rod can not be separately and wire bonds, complicated operation, time-consuming, difficult quality guarantee.
Summary of the invention
Technical problem to be solved in the utility model is to have overcome above-mentioned technological deficiency, and a kind of dependable performance is provided, and is easy to operate, can ensure under the complete satisfactory situation of dielectric strength, and conducting rod is connected with the outside in the middle of can passing sleeve pipe easily.
The utility model comprises: insulated porcelain sleeve, in insulated porcelain sleeve, be provided with conducting rod, and this conducting rod and magnetic insulating sleeve flexibly connect.
On an end of described insulated porcelain sleeve, be provided with annular rill.
Also comprise a lining, this lining is provided with in the middle of magnetic insulating sleeve and the conducting rod.
On the other end of described insulated porcelain sleeve, be provided with external screw thread.
Compared with prior art, the utlity model has following advantage:
1, the utility model comprises magnetic insulating sleeve, flexibly connects conducting rod in magnetic insulating sleeve, and conducting rod had both guaranteed the reliability of insulation, can easily conducting rod be taken off welding lead again, and then in the threading.
2, for increase live part and grounded metal the part along the surface creepage distance, the first half of insulator is done the back-shaped shape of grooving.This conducting rod can want to cooperate with insulator closely, in the middle of the inside of insulator was cast in a tubular brass bushing with epoxy resin, conducting rod passed by in the middle of the brass bushing, is connected with outside lead.At the afterbody of insulator, above with epoxy resin a threaded steel bushing being cast in.Flange seat on the transformer housing that is used for and seals engages.
Description of drawings
Fig. 1 is the utility model structure cut-away view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated: as shown in Figure 1, it comprises magnetic insulating sleeve 1, be provided with conducting rod 4 at magnetic insulating sleeve 1 internal activity, middle injection moulding at conducting rod 4 and magnetic insulating sleeve 1 is fixed with a lining 3, this lining is a brass bushing, is provided with annular rill 11 at an end of magnetic insulating sleeve 1, forms external screw thread 2 on the other end of magnetic insulating sleeve 1 is cast in a threaded steel bushing with epoxy resin.
The utility model embodiment is applied on the flameproof dry type transformer.
