Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.Below in conjunction with accompanying drawing, each preferred embodiment of the present invention is described further:
The embodiment of the present invention provides a kind of draw-gear of transformer, as shown in Fig. 3-Fig. 7, comprising: pull rope 5 and connector 4, and connector 4 is connected with pull rope 5, connector 4 is provided with the first hickey 41; Screw thread middleware 6 is connected with connector 4, screw thread middleware 6 be provided with the first nipple 61 and the second nipple 62, first nipple 61 corresponding with the first hickey 41.
As shown in Figure 3, lead-in wire for band winding outlet 1 take the lead 2 cross-sectional schematic, lead-in wire take the lead 2 afterbody connect winding outlet 1, the second hickey 21 is offered at lead-in wire 2 tops of taking the lead, second hickey 21 is a threaded groove structure, second nipple 62 is corresponding with the second hickey 21, is arranged on the first insulating case 7 outside described connector, can prevent connector from conducting electricity cause danger by the first insulating case.
As shown in Fig. 3-Fig. 7, be connected with connector 4 by pull rope 5, and connector 4 is provided with the first hickey 41, by the first hickey 41 connecting thread middleware 6, screw thread middleware 6 is provided with first nipple 61 corresponding with the first hickey 41, screw thread middleware 6 is also provided with and the second nipple 62 corresponding to the second hickey 21 in 2 of taking the lead that go between, 2 are taken the lead by the second nipple 62 connecting lead wire, pull rope 5 can be conveniently utilized winding outlet 1 to be pulled out the hollow passageway 31 of bushing 3, thus it is simple to make Transformer Winding outlet assemble, improve Transformer Winding packaging efficiency.
