Abstract
The utility model discloses a flat-top bell jar type power transformer body top positioning device which is arranged between a transformer iron core upper beam (4) and a case cover (5). The flat-top bell jar type power transformer body top positioning device comprises laminated wood (1), a positioning nail (2) and a positioning sleeve (3), the positioning nail is vertically welded to the middle portion of a transformer iron core upper beam (4), the positioning sleeve (3) is vertically welded to the middle portion of the case cover (5), and the four faces of the laminated wood (1) are wedged between the positioning pin (2) and the positioning sleeve (3) to fasten the positioning nail (2) and the positioning sleeve (3). The flat-top bell jar type power transformer body top positioning device is firm in positioning and simple in structure, cost of the transformer is reduced, intensity of the transformer case cover is improved and the transformer case cover can be assembled and disassembled for a second time conveniently; the laminated wood is used, the laminated wood has the advantages of being easy to trim, good in insulation performance and long in service life, therefore good positioning performance of the positioning device is guaranteed for a long time and the insulation performance between clamping pieces and an oil tank is ensured.
Description
Technical field
The utility model relates to a kind of flat-top bell glass type electric transformer device body top positioner.
Background technology
In power transformer manufacturing process, all require transformer body fixing reliable, in transportation, the device body will be combined with fuel tank firmly, must not produce relative displacement.
Yet the traditional positioner bolt mechanical positioner and the poured with epoxy resin positioner that arrange between the top cover of existing bell glass type electric transformer and upper beam all have some limitations.The mechanical positioner complex structure, can not insulate between fuel tank and folder, do not meet the requirement of ground connection respectively of transformer core and folder.There is strict demand the poured with epoxy resin location to formula and operating procedure, not location is not firm easily to cause solidification intensity, or produces embrittlement in the long-distance transport process, come off, wear and tear, and causes location not firm, and its powder easily causes secondary pollution to transformer inside, after on-the-spot suspended core, be difficult for resetting.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel flat-top bell glass type electric transformer device body top positioner is provided, and simple in structure, it is firm to locate, and production cost is low, can improve head cover of transformer intensity and installation, convenient disassembly; Use lamination wood, lamination wood there is easy finishing and good insulation property and useful life longer, can ensure for a long time positioning performance that positioner is good and the insulation property between folder and fuel tank.
The purpose of this utility model is achieved through the following technical solutions: bell glass type electric transformer device body top positioner, it is arranged between transformer core upper beam and case lid, it comprises lamination wood, locating pin and positioning sleeve, the locating pin vertical welding is in the middle part of transformer core upper beam, the positioning sleeve vertical welding, in the middle part of case lid, is wedged fastening by lamination wood four sides between locating pin and positioning sleeve.
The beneficial effects of the utility model are: simple in structure, locate firm, reduced the transformer cost, improved head cover of transformer intensity and be convenient to secondary mounting or dismounting; Use lamination wood, lamination wood there is easy finishing and good insulation property and useful life longer, can ensure for a long time positioning performance that positioner is good and the insulation property between folder and fuel tank.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure, 1-lamination wood, 2-locating pin, 3-positioning sleeve, 4-transformer core upper beam, 5-case lid.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1, flat-top bell glass type electric transformer device body top positioner, be arranged between transformer core upper beam 4 and case lid 5, it comprises lamination wood 1, locating pin 2 and positioning sleeve 3, locating pin 2 vertical weldings are in the middle part of transformer core upper beam 4, positioning sleeve 3 vertical weldings, in the middle part of case lid 5, are wedged fastening by lamination wood 1 four sides between locating pin 2 and positioning sleeve 3.
The utility model use procedure is as follows: at transformer core upper beam 4 middle part welding locating pins 2, the positioning sleeve 3 then matched with locating pin 2 in case lid 5 perforate welding.During installation, at first open portable upper cover, it is fastening that lamination wood 1 is wedged on the Zhong Cong top, gap between locating pin 2 and positioning sleeve 3 on four sides, finally loads onto portable upper cover; During dismounting, first open portable upper cover, then utilize instrument to extract lamination wood 1 out and get final product.
