Abstract
The utility model discloses a positioning structure of the lower portion of a transformer iron core. The positioning structure of the lower portion of the transformer iron core comprises a fuel tank, an iron core arranged in the fuel tank, two clamping pieces used for fixing the iron core, a foot pad insulation piece arranged at the bottom of the iron core, a food pad arranged under the foot pad insulation piece, and a foot pad insulation piece installed in a position between the foot pad and the fuel tank. An immobilized cushion block is arranged between the fuel tank and the two clamping pieces and an immobilized cushion block is arranged between the two clamping pieces. The iron core, the clamping pieces and the fuel tank arranged at the positioning structure at the bottom of the transformer are respectively led to be connected with the ground through reliable insulation pieces, and therefore field insulation measurement and malfunction analysis are convenient. By means of a special device used for fixing insulating pieces, reliable insulation among the iron core, the clamping pieces and the fuel tank can be achieved, and by the precise calculation of the compression ratio of the insulating pieces, close fit among the iron core, the clamping pieces and the fuel tank can be achieved; at the same time dislocation can not be caused by long distance transportation, field core-suspending is removed , and due to a concave structure of the lower half section of the fuel tank, materials of the fuel tank can be saved.
Description
Technical field
The utility model relates to a kind of transformer, is specifically related to a kind of transformer core bottom location structure.
Background technology
In the prior art, the iron core in the transformer is directly clamped iron core by two folders usually at two ends, and the feet of iron core below also is directly to be connected with fuel tank, and feet is welded in the fuel tank bottom by locating pin, passes through fastening nuts.Because folder, feet are metal material, in use may the breaking out of fire owing to friction, enterprise is caused damage.In addition because feet lived by location tack welding, in transportation because the situation such as jolt causes feet damaged, when serious even cause the transformer damage.
The utility model content
The purpose of this utility model is to provide a kind of insulation, Stability Analysis of Structures, low, the convenient transformer core bottom location structure that overhauls of cost.
The technical solution of the utility model is: a kind of transformer core bottom location structure, comprise that the feet that arranges between feet, feet and the fuel tank below fuel tank, interior iron core, two folders of secured core, the feet bottom the iron core of fuel tank insulate, feet insulate insulate, be provided with between described fuel tank and the folder and decide the body cushion block, be provided with in the middle of described two folders and decide the body cushion block.
In preferred embodiment of the utility model, second oil tank of described fuel tank becomes concave inward structure.
In preferred embodiment of the utility model, described to decide the body cushion block be the lamination wooden unit.
Described in the utility model is a kind of transformer core bottom location structure, iron core, folder, fuel tank is by reliable insulation and draw respectively ground connection, be convenient to in-site measurement insulation, accident analysis, by isolated plant fixed insulation spare, realize the reliable insulation between iron core, folder, fuel tank and reach by the compression ratio that precision is calculated insulating part closely cooperating, simultaneously long-distance transportation can not cause displacement, and suspended core is exempted from the scene, half-section is concave inward structure under the fuel tank, has saved the materials of fuel tank.
Description of drawings
Fig. 1 is the end view of this transformer core bottom location structure in location structure one preferred embodiment of the utility model transformer core bottom;
Each mark is as follows in the accompanying drawing: 1, fuel tank, 2, iron core, 3, folder, 4, feet, 5, the feet insulation, 6, decide the body cushion block.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
Described in the utility model is a kind of transformer core bottom location structure, as shown in Figure 1: comprise that the insulate feet of feet 4, feet 4 and 1 setting of fuel tank of 5 belows of iron core 2, two folders 3 of secured core 2, the feet insulation 5 of iron core 2 bottoms, feet in the fuel tank 1, fuel tank 1 insulate 5, be provided with between fuel tank 1 and the folder 3 and decide body cushion block 6, be provided with in the middle of two folders 3 and decide body cushion block 6, decide body cushion block 6 and be the lamination wooden unit, has the shoulder to shoulder hardness of iron and steel, and insulation has good security performance and useful life.Second oil tank of fuel tank 1 becomes concave inward structure, has saved the manufactured materials of fuel tank.
Described in the utility model is a kind of transformer core bottom location structure, iron core, folder, fuel tank is by reliable insulation and draw respectively ground connection, be convenient to in-site measurement insulation, accident analysis, by isolated plant fixed insulation spare, realize the reliable insulation between iron core, folder, fuel tank and reach by the compression ratio that precision is calculated insulating part closely cooperating, simultaneously long-distance transportation can not cause displacement, and suspended core is exempted from the scene, half-section is concave inward structure under the fuel tank, has saved the materials of fuel tank.
The above only is embodiment of the present utility model; but protection range of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
Claims (3)
1. transformer core bottom location structure, it is characterized in that: comprise that the feet that arranges between feet, feet and the fuel tank below fuel tank, interior iron core, two folders of secured core, the feet bottom the iron core of fuel tank insulate, feet insulate insulate, be provided with between described fuel tank and the folder and decide the body cushion block, be provided with in the middle of described two folders and decide the body cushion block.
