Description
Technical field
The utility model relates to mining transformer technical field, refers more particularly to a kind of mining explosion-proof transformer.
Background technology
Flameproof dry type transformer to have in the mine of gas and coal dust danger a kind of transformer in generally application, this flameproof dry type transformer needs intensity high usually, the bellows shell mechanism of good heat dissipation, what often adopt at present is the flameproof dry type transformer that Siemens manufactures, outside is spiral welding bellows structure, longitudinally be rolled into corrugated ribbon by band steel, then be connected into corrugated shell by dimensional requirement spiral roll-forming sequential welding.Due to the restriction of conditions down-hole, flameproof dry type transformer generally adopts the type of cooling of air-cooled, and heat radiation is main relies on convection current and thermal radiation.Because the heat dispersion of flameproof dry type transformer directly has influence on its life-span, existing Mine Explosion-proof Dry-type Transformer Enclosure is primarily of casing, case lid, dry-type transformer and the high voltage load switch, the low-voltage vacuum feeding switch that are arranged on casing both sides, by Flange joint or be welded as a whole between casing and case lid, relative flange face utilizes bolted to be sealed and matched, and forms explosion-proof.Flameproof dry type transformer adopts the type of cooling of air-cooled, because dry-type transformer is arranged in casing, heat in casing leans on cross-ventilation and radiant transfer to outside casing, casing selects corrugated steel plate to make, and case lid adopts plain plate to make, in order to reach requirement of explosion proof, thicker steel plate generally chosen by plain plate, waste raw material, radiating effect is poor, afterwards case lid had been made into the surface that a circular arc adds case lid for this reason, add radiating effect, but due to anti-riot requirement will be reached, case lid thickness is still thicker, radiating effect is not clearly.
Chinese patent 201320830758.9 discloses a kind of mining explosion-proof transformer, the flange comprising casing and be connected with casing both sides, case lid, dry-type transformer, the outer wall of the upper end cover of described casing is distributed with many heat conduction bars in " one " font, the cross section of described heat conduction bar is in letter " Y " shape, divide between prong described heat conduction bar upper end " Y " shape and be provided with the first condensation bronze pan tube, the second condensation bronze pan tube is provided with between the root of described heat conduction bar bottom, described first condensation bronze pan tube and the second condensation bronze pan tube all access in the evaporative condenser of peripheral hardware.This utility model can improve himself heat dispersion greatly, improves the stability of transformer work.But this utility model is only provided with heat conduction bar on end cap, radiating effect is not fine, and useful life is not long, haves much room for improvement.
