Be enclosed within described locating pin and pad in described location trepanning and described insulating part bottom, by described locationThe first insulating pad of isolated insulation at the bottom of trepanning and fuel tank;
Be enclosed within described locating pin, pad is at second felt pad at described location trepanning and described insulating part topPlate;
Be arranged on described the second insulating pad described locating pin is fastened on to the securing member on folder.
Preferably, described securing member comprises:
Described locating pin is fastened on to the nut on folder;
The packing ring of pad between described nut and described the second insulating pad.
Preferably, insulating part is made up of multilayer insulation cardboard.
With respect to prior art, the beneficial effects of the utility model are:
The utility model is by weld locating pin at the bottom of transformer oil tank, at locating pin bottom and topThe first insulating pad and the second insulating pad are set, then in the trepanning of location, insulating part are set, realizedInsulation between folder and locating pin, and insulation between at the bottom of folder and fuel tank. Meanwhile, in locationInsulating part is set in trepanning can also be clamped locating pin, improves the stability of structure.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below willAccompanying drawing to required use in embodiment or description of the Prior Art is briefly described, apparently,Accompanying drawing in the following describes is only embodiment more of the present utility model, for ordinary skill peopleMember, is not paying under the prerequisite of creative work, can also obtain the attached of other according to these accompanying drawingsFigure.
A kind of knot of drawing separately the lower location structure of ground connection for folder that Fig. 1 provides for the utility modelStructure schematic diagram.
Detailed description of the invention
Refer to Fig. 1, Fig. 1 draws separately the lower location knot of ground connection for what the utility model provided for folderThe structural representation of structure. The utility model provides a kind of lower location knot of drawing separately ground connection for folderStructure, mainly comprises locating pin 1, insulating part 2, the first insulating pad 3, the second insulating pad 4 and securing members.Wherein, locating pin 1 is welded at the bottom of transformer oil tank on 8. On the clamping plate of apparatus for fixing transformer 7, offer oneThe individual location trepanning 1s mating with locating pin 1, location trepanning 1s is enclosed within locating pin 1, with realize folder 7 withConnection at the bottom of fuel tank between 8. In the trepanning 1s of location, be enclosed with insulating part 2 around locating pin 1 lateral surface,Insulating part 2 can clamp locating pin 1 on the one hand in the trepanning 1s of location, can realize on the other hand locating pin 1 withInsulation between folder 7. In locating pin 1, cover has the first insulating pad 3, the first insulating pads 3 to be arranged onLocating pin 1 and trepanning 1s bottom, location, and pad is at the bottom of insulating part 2 and transformer oil tank between 8, makes to locate8 isolated insulations at the bottom of trepanning 1s and fuel tank. Meanwhile, in locating pin 1, also cover has the second insulating pad 4, theTwo insulating pads 4 pad the top at location trepanning 1s and insulating part 2. Be provided with at the second insulating pad 4 topsA securing member, securing member is fastened on locating pin 1 on folder 7, makes folder 7 and 8 fastening companies at the bottom of fuel tankConnect.
The utility model is by weld locating pin at the bottom of transformer oil tank, at locating pin bottom and topThe first insulating pad and the second insulating pad are set, then in the trepanning of location, insulating part are set, realizedInsulation between folder and locating pin, and insulation between at the bottom of folder and fuel tank. Meanwhile, in locationInsulating part is set in trepanning can also be clamped locating pin, improves the stability of structure.
Securing member can comprise packing ring 5 and nut 6, and packing ring 5 is arranged on the second insulating pad 4 tops, nut 6Be arranged on packing ring 5 tops, nut 6 is fastened on locating pin 1 on folder 7 by screwing.
Insulating part 2 in the present embodiment can be made up of multilayer insulation cardboard, or other have insulation characterisiticMaterial form.
The lower location structure of drawing separately ground connection for folder that the utility model provides not only can make folder withLocating pin, fuel tank effectively insulate, but also can pass through insulating part stretching locating pin, reduce transformerDisplacement and vibrations in transport and running.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can be realized or useThe utility model. To be aobvious for those skilled in the art to the multiple amendment of these embodimentAnd easily see, General Principle as defined herein can not depart from spirit or scope of the present utility modelSituation under, in other embodiments realize.
