Abstract
The utility model discloses a kind of transformer footing, comprise feet, feet cushion block, feet insulation, wherein, feet cushion block is symmetrical placement placed in the middle above feet, has feet to insulate, to reduce the vibration between iron core and device body between feet cushion block and feet; The stepped structure of feet cushion block, matches with ladder unshakable in one's determination, unshakable in one's determination with classification support; Fluting is arranged at the bottom of feet cushion block, the width that the width of this groove insulate slightly larger than feet, so that feet cushion block is set up in above feet insulation.The utility model can reach the functions such as location, insulation, noise reduction simultaneously, technique is simple, there is installation convenient, reliable in function, be applicable to the advantages such as all size type transformer, device for positioning and supporting, seal, denoising device are effectively combined, significantly reduces the noise and no-load loss that produce in operation.
Description
Technical field
The utility model belongs to field transformer, is specifically related to a kind of transformer footing.
Background technology
Along with the raising of industrial level, the demand of transformer increases year by year, is also improving the performance requirement of transformer always, the two large problems in transformer running: noise and loss are the emphasis paid close attention to.The design of feet directly affects the performance of transformer, and transformer footing is between iron core and fuel tank, device body and fuel tank is located, feet cushion block supporting iron core, and makes insulation against ground unshakable in one's determination.
In prior art, feet uses poured with epoxy resin, epoxy resin material is hard, not yielding after being heated, add the mechanical strength of transformer, but meanwhile there is another shortcoming: in transformer running, if vibration occurs can not shift rapidly, cause no-load loss unshakable in one's determination to increase, then noise increases.In addition, epoxy resin cost is high, has high input, and causes transformer producer profit to reduce.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of novel transformer footing, by device body and fuel tank compact siro spinning technology, can reduce the noise produced in running by rational design, keeps unshakable in one's determination complete and firm, reduction no-load loss simultaneously.
To achieve these goals, the technical solution of the utility model is:
A kind of transformer footing, comprises feet, feet cushion block, feet insulation, and wherein, feet cushion block is symmetrical placement placed in the middle above feet, has feet to insulate, to reduce the vibration between iron core and device body between feet cushion block and feet; The stepped structure of feet cushion block, matches with ladder unshakable in one's determination, unshakable in one's determination with classification support; Fluting is arranged at the bottom of feet cushion block, the width that the width of this groove insulate slightly larger than feet, so that feet cushion block is set up in above feet insulation.
Feet cushion block of the present utility model adopts the wooden one-tenth of lamination, has certain expansion-contraction ability, with feet insulated combination, can reduce the vibration of transformer better, reduces noise; In addition feet cushion block is stepped, becoming a firmly entirety, effectively can bear iron core weight, reducing the downward shift when vibrating unshakable in one's determination with compact siro spinning technology unshakable in one's determination; Feet cushion block lower end fluting simultaneously, the horizontal-shift caused when can reduce vibration, makes maintenance fixed position relative unshakable in one's determination, reduces iron coring vibration amount, reduce no-load loss.The utility model is simple and reliable for structure, simple for process, guarantees that transformer performance is reliable.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model feet cushion block schematic three dimensional views.
Fig. 3 is the utility model feet cushion block cutaway view.
Mark representative in figure: 1, feet; 2, feet cushion block; 3, feet insulation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
After the cartonning of device body, overall appearance as shown in Figure 1, and item 1 is feet, and item 2 is feet cushion block, and item 3 is feet insulation, clearly can find out feet and position relationship that is unshakable in one's determination and fuel tank in figure.
Feet tapping communicates with fuel tank locating pin, and device body is located; Screw rod is connected with lower clamping piece perforate, channel steel support lower clamping piece, and device body is reliably connected with feet, ensures mechanical strength enough between unshakable in one's determination and feet, reduces vibration.Transformer core is placed on feet cushion block, and feet cushion block, in the middle of feet, is placed between two parties.Ladder-shaper structure and ladder unshakable in one's determination coincide.Feet cushion block and feet centre are placed with rubber feet and insulate, and reduce the vibration between unshakable in one's determination and device body.
Feet cushion block as shown in Figure 2,3, adopts step structure, and classification support is unshakable in one's determination, ensures every grade of uniform force unshakable in one's determination, reduces no-load loss.Feet cushion block bottom fluting, cell body frame in FIG item 3 feet insulation on, groove width slightly larger than the width of item 3, can suppress well cushion block due to vibration produce horizontal displacement.
During use, this design can reach the functions such as location, insulation, noise reduction simultaneously, technique is simple, there is installation convenient, reliable in function, be applicable to the advantages such as all size type transformer, device for positioning and supporting, seal, denoising device effectively combined, significantly reduces the noise and no-load loss that produce in operation.
The utility model is not limited to above-described embodiment, and all technical schemes adopting equivalent replacement or equivalence replacement to be formed all belong to the claimed scope of the utility model.
