Abstract
The invention discloses a supporting structure for a body of an epoxy cast dry-type transformer. The structure comprises a trolley foot, a supporting seat, supporting feet and a bottom foot insulator. The supporting seat and the supporting feet are arranged on the trolley foot, and the supporting feet are located on the outer side of the supporting seat. The bottom foot insulator is flatly laid on the upper surface of the supporting seat, and positioning pin shafts are arranged among the trolley foot, the supporting seat and the bottom foot insulator. The supporting feet are formed by welding box iron, and the supporting seat is formed by bending a steel plate, adding a sealing plate and welding the sealing plate. According to the supporting structure, the ground clearance of the body of the transformer can be adjusted, it is ensured that the enough air amount exists between the body and the ground surface, and temperature rising is reduced; meanwhile, the length of an outlet copper bar is reduced, and cost is saved.
Description
Technical field
The invention belongs to transformer manufacture technology, relate to a kind of supporting construction of epoxy cast dry transformer device body.
Background technology
The footing support structure of conventional epoxies dry-type transformer as shown in Figure 1 to Figure 3.Dolly pin 11 is placed footing insulation 12, support set 13 is placed at the two ends of footing insulation.After dry change device body has assembled, distinguish load-bearing on support set and footing insulate with the lower surface of lower clamping piece 14 and device body 15, with bolted, completed assembling.This structure is continued to use on circle core configuration always, and structure is simple, easy to assembly.
But in recent years, the version of transformer coil is toward Long Circle development, and along with the progressively reduction of iron core diameter, the ground clearance that result in transformer body also diminishes thereupon.Bring Railway Project thus: because the reduction of the distance on transformer body and ground, make the air line distance of installing cooling fan inadequate, had a strong impact on the assembling of blower fan; Ground clearance is too small, and the air total amount needed for transformer heat radiation is affected, and causes air to flow not smooth, the temperature rise of transformer is raised; Device body height reduction, on transformer, outlet copper bar length must increase, and adds cost, causes the discontented of client.
Summary of the invention
The object of this invention is to provide a kind of supporting construction of epoxy cast dry transformer device body, this supporting construction can regulate the terrain clearance of transformer body, ensure that there are enough air capacities between device body and ground, reduces temperature rise; Decrease the copper bar length of outlet simultaneously, save cost.
Object of the present invention is achieved through the following technical solutions:
A supporting construction for epoxy cast dry transformer device body, is characterized in that: this structure comprises the insulation of dolly pin, supporting seat, feet and footing, and supporting seat and feet are all arranged on dolly pin, and feet is positioned at outside supporting seat; Footing insulation is laid in supporting seat upper surface; Alignment pin is equipped with between the insulation of dolly pin, supporting seat and footing.
In the present invention, feet is welded by channel-section steel.Supporting seat, by steel plate bending, adds shrouding and is welded.
The present invention changes former support set structure into be welded by channel-section steel feet, increases supporting plane, to ensure that transformer body has enough stability after raising.Thicken footing insulation, to strengthen buffering to transformer body and the suction effect of making an uproar.Increase supporting seat, supporting seat by steel plate bending, then adds shrouding and is welded.During assembling, supporting seat is placed on dolly pin, upper tiling footing insulation, be equipped with alignment pin between the insulation of dolly pin, supporting seat and footing, in order to ensure the reliability of assembling, finally device body be placed on feet and footing insulation, fix with securing member, complete assembling.
The invention has the advantages that: by the terrain clearance regulating the height of feet and supporting seat to regulate transformer body, ensure that there are enough air capacities between device body and ground, reduce temperature rise.Through verification experimental verification, the temperature rise of transformer reduces 2-3K.The insulation of dolly pin, supporting seat and footing is equipped with the bearing pin in order to location, ensure that the reliability of assembling.Install to transformer cooling fan and be reserved with sufficient space, meet blower fan matching requirements.Along with the rising of device body, the copper bar length for outlet can be reduced, reduce cost.

Embodiment
A supporting construction for epoxy cast dry transformer device body, is shown in Fig. 4 and Fig. 5, and this structure comprises dolly pin 1, supporting seat 2, feet 3 and footing insulation 4, and supporting seat and feet are all arranged on dolly pin, and feet is positioned at outside supporting seat; Feet is welded by channel-section steel.Supporting seat, by steel plate bending, adds shrouding and is welded.Footing insulation is laid in supporting seat upper surface; Alignment pin is equipped with between the insulation of dolly pin, supporting seat and footing.
The present invention changes former support set structure into be welded by channel-section steel feet, increases supporting plane, to ensure that transformer body 5 has enough stability after raising.Thicken footing insulation, to strengthen buffering to transformer body and the suction effect of making an uproar.Increase supporting seat, supporting seat by steel plate bending, then adds shrouding and is welded.During assembling, lower clamping piece 6 is connected with feet; Be placed on by supporting seat on dolly pin, upper tiling footing insulation, is equipped with alignment pin between the insulation of dolly pin, supporting seat and footing, in order to ensure the reliability of assembling, finally device body is placed on feet and footing insulation, fixes with securing member, complete assembling.
Facts have proved, this structure is reliable and stable in the application.This structure farthest ensures and improves the performance of product, has saved cost, creates great social and economic effects.
