Abstract
This utility model relates to a flame-proof shell of a mine flame-proof solid-transformer, which comprises a terminal ring melded to the side of a flange and an accordion pipe melded to the interior side of the terminal ring. A dabber and a rail angle-bar are melded with the interior wave crest of the accordion pipe, and both terminals are melded to the terminal ring and interior side of the flange. A supporting angle is melded to the terminal ring and the flange and a low pin is connected with a support leg through fasteners. A guiding dissipating heat intensifying board is melded to the exterior wave crest of the accordion pipe. This utility model has the advantages of simplified shell body manufacturing arts, adequate shell body bearing, large heat dissipating area, good heat dissipating conditions, reduced weight. The top of the shell is not prone to dust and water accumulation. This utility model has the advantages of graceful appearance and close conformation, thereby being conveniently applied in the conveyance, installment and application in special environment of underground mining. This utility model is further provided with integral intensity, and thereby passing the water pressure test and flame-proof test, and totally meeting the requirements of the tests.
Description
Technical field
The utility model relates to a kind of flameproof enclosure of flameproof dry type transformer, described flameproof enclosure is meant and contains dry-type transformer device body, electric component or the whole shell wall of circuit and door, lid, observation window and the cable entry etc. on the shell wall.This flameproof enclosure should be able to bear the blast pressure of shell implode admixture of gas, and can stop internal explosion flame and product to the shell external communication.Belong to the transformer technology field.
Background technology
The flameproof dry type transformer flameproof enclosure generally adopts rectangular structure at present.This flameproof enclosure is welded by the several piece steel plate, because the welding position is more, is the anti-quick-fried and explosion insulation performance that guarantees housing, selects for use the steel plate can not be too thin, and through welding is answered in the welding position, can not have the rosin joint position, and processing capacity is big, and man-hour is long.Casing and end cap flange are rectangle, each position discontinuity of flange, and often the diameter by thickening flange thickness and bolt solves.The area of dissipation of housing is little in addition, for guaranteeing the transformer temperature rise value, can only strengthen shell sizes.The volume and weight of flameproof enclosure is improved greatly, be unfavorable for the transportation and the use of particular surroundings under the coal mine.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of blast pressure that can bear shell implode admixture of gas, and can stop internal explosion flame and the product Mine Explosion-proof Dry-type Transformer Enclosure to the shell external communication.Technical solution of the present utility model: its structure is that the end circle is welded on the side of flange, bellows is welded on the inboard of end circle, the inboard crest spot welding of reinforcement and track angle steel and bellows, two ends are welded in the inboard of end circle and flange, strut angle is welded on end circle and the flange, low pin and feet connect by securing member, guiding heat radiation stiffener and the crest spot welding of the bellows outside.
Advantage of the present utility model: simplified the housing manufacturing process, make housing stressed more even, and area of dissipation has been big, case top is difficult for laying dust, ponding, and radiating condition is good, and volume is little, weight reduction.Good looking appearance.Adopt circular configuration, not only compact conformation, good looking appearance also are convenient to transportation, installation and the use of particular surroundings under the coal mine; And good integral strength, by carrying out the test of the hydraulic test and flame proof, satisfy test requirements document fully.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is left views of Fig. 1
Accompanying drawing 3 is the A-A cutaway views among Fig. 2
Accompanying drawing 4 is instance graphs that the utility model is used for flameproof dry type transformer KBSG2-T-200/10
Among the figure 1 is bellows, the 2nd, hang mix, the 3rd, end circle, the 4th, flange, the 5th, guiding heat radiation stiffener, the 6th, feet, the 7th, low pin, the 8th, reinforcement, the 9th, track angle steel, the 10th, fixed head, the 11st, transformer body, the 12nd, flame proof housing, the 13rd, cross-over block.
Embodiment 4
The contrast accompanying drawing, its structure is that end circle 3 is welded on the side of flange, bellows 1 is welded on the inboard of end circle 3, reinforcement 8 and track angle steel 9 and bellows 1 inboard crest spot welding, two ends are welded in the inboard of end circle 3 and flange 4, feet 6 is welded on end circle 3 and the flange 4, and low pin 7 and feet 6 connect by securing member, guiding heat radiation stiffener 5 and bellows 1 outside crest spot welding.
Contrast Fig. 4, the transformer upper clamping piece connects by fixed head 10 and flame proof housing top reinforcement 8, and lower clamping piece and track angle steel 9 connect by securing member, fill up tightly and with securing member with cross-over block 13 between iron core and the flame proof housing 12 bottom reinforcements and fix.
During making, housing adopts radiatinig corrugated Guan Yuduan circle and flange to be welded.Radiatinig corrugated Guan Weida ripple small echo adopts a hydroforming of high-quality deep drawing sheet apart from structure, makes its intensity height, and area of dissipation is big.The flange cross section is circular, and each one is stressed evenly, processes easy.Housing when welding, will hold circle to be welded on the flange earlier, then bellows and end circle are welded, at last in enclosure interior along the circumference reinforcement of evenly burn-oning.
