Abstract
The utility model discloses a positioning nail insulating sleeve type structure of an electric furnace transformer. The positioning nail insulating sleeve type structure of the electric furnace transformer is composed of a screw, a positioning part, an insulating sleeve and a positioning nail, wherein the positioning nail is welded to the bottom of an oil tank of the transformer, the positioning nail is sleeved with the positioning part, the positioning part is sleeved with the insulating sleeve, and the screw is connected into the positioning nail in a screwed mode; when the oil tank of the transformer is produced, the positioning nail is welded to the bottom of the oil tank of the transformer, and after other assemblies of the transformer are produced and used for general assembly, the screw, the positioning part and the insulating sleeve are sequentially installed on the positioning nail. When the structure body is installed for general assembly, holes opened in a pad foot and the insulating sleeve of the positioning nail are matched and installed in the corresponding positions. After the positioning nail insulating sleeve type structure is adopted, the body of the transformer and an external oil tank iron part can be effectively insulated, the grounding current of the body of the transformer can be well monitored, the phenomenon that the transformer is grounded through multiple points occasionally because of the positioning nail is eradicated, and the body of the transformer becomes a full-insulation type structure.
Description
Technical field
The utility model relates to a kind of furnace transformer, particularly a kind of furnace transformer locating pin insulating case cartridge type structure.
Background technology
At present, existing furnace transformer locating pin structure is a kind of mode that generally adopts round steel nail location, the furnace transformer location of this kind of structure, can not effectively insulate the device body of transformer and external fuel tank ironware, also there will be once in a while the phenomenon that makes transformer produce multipoint earthing etc.; Can not well monitor transformer body earth current size.
Summary of the invention
The purpose of this utility model is to have the not good problem of insulation property in order to solve existing furnace transformer locating pin structure, and a kind of furnace transformer locating pin insulating case cartridge type structure providing.
The utility model is made up of screw, keeper, insulating sleeve and locating pin, and locating pin is welded in transformer oil tank bottom, and keeper is set in outside locating pin, and insulating sleeve is enclosed within outside keeper, and screw is screwed onto in locating pin.
Installation process of the present utility model:
In the time that oil tank of transformer is produced, locating pin is welded in transformer oil tank bottom, carry out general assembly after other assembly of transformer produces into time, then screw, keeper and insulating sleeve is installed in locating pin successively.While carrying out the installation of general assembly orchestration body, the perforate in feet is coordinated to installation with the insulating sleeve correspondence position of locating pin.
The beneficial effects of the utility model:
Adopt after locating pin insulating case cartridge type structure, the device body of transformer and external fuel tank ironware effectively can be insulated, well monitor body earth current size, stop, because the transformer that makes once in a while that locating pin causes produces the phenomenon of multipoint earthing, transformer body to be made to all insulation formula structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is that the utility model uses view.
Embodiment
Referring to shown in Fig. 1, is embodiment of the present utility model, is made up of screw 1, keeper 2, insulating sleeve 3 and locating pin 4, locating pin 4 is welded in transformer oil tank bottom A, keeper 2 is set in outside locating pin 4, and insulating sleeve 3 is enclosed within outside keeper 2, and screw 1 is screwed onto in locating pin 4.
The installation process of the present embodiment:
Refer to shown in Fig. 1 and Fig. 2, in the time that oil tank of transformer is produced, locating pin 4 is welded in transformer oil tank bottom A, carry out general assembly after other assembly of transformer produces into time, then screw 1, keeper 2 and insulating sleeve 3 are installed in locating pin 4 successively to the final structure forming as shown in Figure 1.While carrying out the installation of general assembly orchestration body, the perforate B1 on feet B is coordinated to installation with insulating sleeve 3 correspondence positions, be structure shown in Fig. 2.
