Abstract
The utility model relates to an explosion-proof housing of an explosion-proof dry-type transformer or a movable substation for mining, belonging to electromechanics. The explosion-proof housing adopts a corrugated cylinder-shaped structure with end rings and flanges at two ends welded together to form the cylinder-type explosion-proof housing; sufficient strengthening ribs are welded on the inner wall of the explosion-proof housing along the circumference; and both the explosion-proof housing and accessories adopt austenite low-magnetic-conductive stainless steel. By adopting the scheme, the anti-explosion housing has moisture-proof property and corrosion resistance, eddy loss and large heat equivalent area caused by leakage magnetic field of a transformer are reduced; by adopting the austenite low- magnetic-conductive stainless steel, the integral volume of the explosion-proof housing is reduced, and smaller overall size and light weight are realized; and the explosion-proof housing suitable for underground transport in mine has the advantages of good manufacturability, easiness in mechanical processing, etc.
Description
Technical field
The utility model relates to electrical category, and particularly a kind of flameproof dry type transformer and mobile substation flameproof enclosure refer to have little, in light weight, the moistureproof good corrosion resistance of volume especially, reduce the flameproof mining mobile transformer substation flameproof enclosure of stray loss.
Background technology
At present, existing flameproof dry type transformer and mobile substation flameproof enclosure adopt the general steel plate welded structure, and housing is up and down a circular arc, and upright corrugated plating is welded in both sides.The requirement of GB 3836.1-2000 and GB 3836.2-2000 though can be up to state standards still has the following disadvantages:
1. volume is big, Heavy Weight, transportation inconvenience in the underworkings of colliery;
2. there was dampness in the air under the coal mine, and have corrosivity, and after operation a period of time, the shell corrosion makes explosion insulation performance descend, and when the blast situation appears in dry-type transformer, can't guarantee original explosion insulation performance;
3. when transformer moved, its shell was in the stray field of transformer, and self produces eddy current, and then eddy current loss occurs, made transformer efficiency reduce.
Along with the further raising that mine safety is required, the problem of above-mentioned existence, particularly security hidden trouble need further to be improved.
The utility model content
The purpose of this utility model is to provide a kind of flameproof dry type transformer and mobile substation flameproof enclosure, overcome the transportation inconvenience of present flameproof dry type transformer and mobile substation, be corroded and deficiency such as shell eddy current loss is big easily, and adopt a kind of flameproof enclosure of new material new construction, not only have little, in light weight, the moisture resistance corrosion resistant characteristics of volume, and mine explosion-suppression dry-type transformer and mobile substation are when work, the eddy current loss that shell produces is very little, has improved the efficient of transformer.
The technical scheme that the utility model adopted is: this flameproof enclosure adopts the ripple cylinder type, is welded into one with two end flanges by the end circle, constitutes the cartridge type flameproof enclosure; For making shell have enough axial mechanical strengths, wall is along the enough reinforcements of circumference welding in the enclosure.The material of its ripple cylinder type and annex selects for use austenite to hang down magnetic stainless steel, and this material has low magnetic conductivity, has reduced the eddy current loss that Magnetic Leakage Field of Transformer caused, and has improved the joint performance of transformer.Housing adopts wave structure, has increased the equivalency tables area greatly, has improved heat-sinking capability.
The beneficial effects of the utility model are, selected the ripple barrel shrond of austenitic stainless steel material for use, make explosion-resistant enclosure have moistureproof corrosion resistance, reduced the eddy current loss that Magnetic Leakage Field of Transformer caused, the heat radiation equivalent area is big, dwindled overall volume, it is less, in light weight to have overall dimension, is fit to transport under the coal mine.And moisture resistance corrosion-resistant, axial strength is high, good manufacturability, be easy to advantages such as machining.
