The outer sleeve pipe of pipe can seepage water -cooling liquid directly gets into the transformer oil in the oil tank after effectively having stoped the pipe to damage, has improved transformer oil's quality and has protected the insulating fibre, with the anti -aging. When pipe seepage water -cooling liquid, in water -cooling liquid can get into the gap of sleeve pipe and pipe, along with the outflow of pipe outer wall, staff's discovery had the water -cooling to flow out night, the timely pipe of more renewing.
Description
Technical field
The utility model relates to a kind of transformer, is specifically related to a kind of water-cooled oil-filled transformer.
Background technology
Transformer is by type of cooling classification: dry type (self cooling) transformer, oil immersion (self cooling) transformer, fluoride (evaporative cooling) transformer.The cooling system of tradition oil-filled transformer, generally has Natural Oil Circulation Power air cooling system, forced oil-circulation air cooling system, forced oil circulation water-cooling system etc.Front a kind of situation being only applicable to unit low capacity, along with the continuous growth of transformer single-machine capacity, its type of cooling is more and more fixed against latter two.
Forced oil circulation water-cooling system adopts water as the heat transferring medium of transformer oil, use water cooler, transformer oil side and water side all add pump forced circulation, but some adopt the oil-filled transformer of water-cooling system, water-cooled fluid catheter is generally arranged on outside fuel tank, when transformer runs, the heat that iron core and coil produce first passes to transformer oil, tank envelope is transferred heat to by transformer oil, heat is taken away by the circulation of water-cooled liquid by the water-cooled fluid catheter of fuel tank arranged outside again, because transformer oil is coolant, its electric property is good, but heat conductivility is poor, and heat passes through multi-dielectric, heat conductivility and radiating efficiency lower, and water-cooled fluid catheter long term exposure is oxidized in atmosphere, rapidly aging, useful life is short, radiating effect also can decline thereupon.For the Chinese patent 201320365905.X that solves the problem discloses a kind of water-cooled oil-filled transformer, technical characteristics is wound with conduit outside coil, has water cooling medium in conduit.But if the shortcoming existed, conduit percolating water medium, non-conductive fibre can be impelled aging, and the molecule of non-conductive fibre is glucose (C

6) molecule, moisture reduces its gravitation after entering fiber molecule, impels it to be hydrolyzed into low molecular material, reduces fibre machinery intensity and the degree of polymerization; And the seepage of water affects the quality of transformer oil, accelerated ageing.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of water-cooled oil-filled transformer.
The technical solution adopted in the utility model is:
A kind of water-cooled oil-filled transformer, comprise the fuel tank that sealing is arranged and the iron core be arranged in fuel tank, described iron core is wound with coil, and described fuel tank is built with transformer oil, and described iron core and coil are immersed in transformer oil,
Be wound with sleeve pipe outside described coil, be provided with conduit in described sleeve pipe, conduit is connected with the pump outside fuel tank, is connected with water-cooled liquid in described conduit.
Preferably, the diameter 1 ~ 4mm larger than the diameter of conduit of described sleeve pipe, through verification experimental verification, the design of these data can not affect the cooling effect that conduit has.
Preferably, the sleeve pipe outside oil tank of transformer is provided with transparent visual part, and the corresponding conduit outer wall in this place is provided with meets water Allochroic label, if conduit seepage water-cooled night, flow to the transparent visual part place of casing part along conduit outer wall, distilled water meets test paper variable color, and prompting staff keeps in repair conduit.
Also can be provided with on the inwall of sleeve pipe transparent visual part and meet water Allochroic label, if conduit seepage water-cooled night, flow to the transparent visual part place of casing part along internal surface of sleeve pipe, distilled water meets test paper variable color, and prompting staff keeps in repair conduit.
Preferably, inert gas conveying equipment is connected between described sleeve pipe and conduit, before use, air between sleeve pipe and conduit is adopted inert gas replacement, both the variable color of condensed water dirty chance label had been prevented, mislead staff and change conduit, prevent from again entering in oil tank of transformer during casing failure being oxidized transformer oil.
Preferably, described sleeve pipe and conduit are made by oil resistance material, prevent the corrosion being subject to transformer oil.
Preferably, described water-cooled liquid is distilled water.Even if sleeve pipe and conduit leak fluid, distilled water is nonconducting water-cooled liquid, has good mobility and water-cooled effect, uses more safe and reliable.
The beneficial effects of the utility model are: the sleeve pipe outside conduit, directly can enter in the transformer oil in fuel tank by seepage water-cooled liquid, improve the quality of transformer oil and protect non-conductive fibre, with anti-aging after effectively preventing conduit to damage.When conduit seepage water-cooled liquid, water-cooled liquid can enter in the gap of sleeve pipe and conduit, flows out with conduit outer wall, and staff finds that there is water-cooled and flows out night, the conduit more renewed in time.
