Description
Technical field:
The utility model relates to field transformer, relates in particular to the fuse that is used for transformer, particularly a kind of high-tension fuse that is used for buried transformer.
Background technology:
Need to adopt fuse to connect high-tension line in the electic protection loop of transformer,, need to adopt the high fuse of insulation property grade owing to have high pressure in the transformer.In the prior art, high-tension fuse adopts the high-tension fuse that is used for buried transformer of box-type.The high-tension fuse of this box-type only is suitable for sealed transformer and composite type box type transformer, and its transformer case degree of protection does not reach the IP68 standard, so can not be used for buried transformer.
Summary of the invention:
The purpose of this utility model provides a kind of high-tension fuse that is used for buried transformer, and the described this high-tension fuse that is used for buried transformer will solve high-tension fuse insulation property deficiency of the prior art, can not be used for the technical problem of buried transformer.
This high-tension fuse that is used for buried transformer of the present utility model is made of an insulating joint seat, wherein, be provided with high pressure fusion tube cavity volume in the described insulating joint seat, one end of insulating joint seat is provided with seal cover, the outer face of described seal cover is circular cone shape, the outer end circumference of seal cover is provided with spiral cover, described spiral cover is connected with the insulating joint seat by screw thread, the other end of insulating joint seat is embedded with a following contact, the inboard in insulating joint seat stage casing is embedded with the upper contact head of an annular, and described upper contact head is provided with a connecting rod.
Further, be provided with a high pressure fusion tube in the described high pressure fusion tube cavity volume, one end of described high pressure fusion tube is connected with a rotating part, the outer end of described rotating part is connected with an inner handle, described inner handle is between the lower end and upper contact head of seal cover, and the other end of high pressure fusion tube is connected with described contact down.
Further, described insulating joint seat is inserted in the inner of described seal cover, is provided with sealing ring between seal cover and the insulating joint seat.
Further, described insulating joint seat is cylindrical shape.
Further, described contact down is made of cylinder copper tube.
Further, described high pressure fusion tube cavity volume is cylindrical tube.
Operation principle of the present utility model is: the high pressure fusion tube inserts in the insulating joint seat, is connected with inlet wire by upper contact head, is connected with transformer coil by following contact, for transformer provides high voltage protective.The insulating joint seat is by seal cover and spiral cover sealing, and insulation property are good, enough are used for buried transformer.
Concrete, inner handle described in the utility model, rotating part, sealing ring and high pressure fusion tube all adopt known schemes of the prior art, about the known solution of inner handle, rotating part, sealing ring and high pressure fusion tube, those skilled in the art all understands, and does not repeat them here.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged on cylinder barrel shaped insulating joint seat in the high-tension fuse, and contact adopts embedded mode to be arranged in the insulating joint seat, and favorable sealing property is applicable to buried transformer, and simultaneously, it is convenient that the plug of high pressure fusion tube is changed.
Description of drawings:
Fig. 1 is the axial section structural representation that is used for the high-tension fuse of buried transformer of the present utility model.
Embodiment:
As shown in Figure 1, the high-tension fuse that is used for buried transformer of the present utility model, constitute by an insulating joint seat 4, wherein, be provided with high pressure fusion tube cavity volume in the described insulating joint seat 4, one end of insulating joint seat 4 is provided with seal cover 1, the outer face of described seal cover 1 is circular cone shape, the outer end circumference of seal cover 1 is provided with spiral cover 2, described spiral cover 2 is connected with insulating joint seat 4 by screw thread, the other end of insulating joint seat 4 is embedded with a following contact 8, is embedded with the upper contact head 6 of an annular on the insulating joint seat 4 on the inboard in stage casing, and described upper contact head 6 is provided with a connecting rod 10.
Further, be provided with a high pressure fusion tube 7 in the described high pressure fusion tube cavity volume, one end of described high pressure fusion tube 7 is connected with a rotating part 5, the outer end of described rotating part 5 is connected with an inner handle 3, described inner handle 3 is between the end face of seal cover 1 and lower end and upper contact head 6, and the other end of high pressure fusion tube 7 is connected with described contact 8 down.
Further, described insulating joint seat 4 is inserted in the inner of described seal cover 1, is provided with sealing ring 9 between seal cover 1 and the insulating joint seat 4.
Further, described insulating joint seat 4 is cylindrical shape.
Further, described contact 8 down is made of cylinder copper tube.
Further, described high pressure fusion tube cavity volume is cylindrical tube.
Operation principle of the present utility model is: the high pressure fusion tube inserts in the insulating joint seat 4, is connected with inlet wire by upper contact head 6, is connected with transformer coil by following contact 8, for transformer provides high voltage protective.Insulating joint seat 4 is by seal cover 1 and spiral cover 2 sealings, and insulation property are good, enough are used for buried transformer.
