Cooler 3 described in the utility model is finned wind/liquid cooling heat exchanger or coiled tubular wind/liquid cooling heat exchanger.
Utility model works process:
Vacuum oil: under oil tank of transformer 1 entirety is placed in vacuum environment, outside fuel injection pipe is connected with fuel feeding valve 1-2, and opens fuel feeding valve 1-2; After insulating oil fills fuel tank, more namely the peak pouring in oil tank of transformer 1 collects exhaust cap 1-1, then injects the first accumulator 2-1 of oil conservator 2 by third connecting pipe 5; After the first accumulator 2-1 of oil conservator 2 fills, insulating oil is by injecting in the second accumulator 2-2 of oil conservator 2 the 4th communicating pipe 6; By observing liquid level meter 8, determining whether the oil level in the second accumulator 2-2 of oil conservator 2 reaches designing requirement, now, stopping oiling, closing fuel feeding valve 1-2, pull down outside fuel injection pipe, complete the oiling of oil tank of transformer 1.
Oil conservator stores and compensates insulating oil: when transformer runs, can loss be there is in its insulating oil, and the insulating oil in heating transformer fuel tank 1, oil temperature is made to increase, and cause insulating oil volume to expand, and the insulating oil expanded out can be pressed into the first accumulator 2-1 of oil conservator 2 by third connecting pipe 5, insulating oil unnecessary in first accumulator 2-1 is by being pressed into the second accumulator 2-2 of oil conservator 2 the 4th communicating pipe 6, pass oily process until ambient atmosphere to the pressure of insulating oil in the second accumulator 2-2 and the cover plate of oil tank of transformer 1 to insulating oil pressure dynamic equilibrium in fuel tank till, complete the transmission of oil just now, when transformer power output diminishes or transformer quits work, because its heating reduces, and oil temperature declines, the volume of insulating oil can shrink reduction, now, ambient atmosphere is broken the dynamic equilibrium of insulating oil pressure in fuel tank the pressure of insulating oil in the second accumulator 2-2 and the cover plate of oil tank of transformer 1, external atmosphere pressure is made to force the insulating oil in the second accumulator 2-2 of oil conservator 2 to enter the first accumulator 2-1 of oil conservator 2, finally enter in oil tank of transformer 1, realize the compensation to insulating oil in oil tank of transformer 1.
Insulating oil expands and discharges gas in fuel tank: transformer is in During Process of Long-term Operation, insulating oil can slow degradation and decomposition, generating portion gas, and gas collection is many can the insulation of lowering device body, also the cooling of device body is unfavorable for, so the eliminating that equipment must be had to realize gas.Therefore, insulating oil in oil tank of transformer 1 decomposes the gas produced can come together in peak collection exhaust cap 1-1, when the insulating oil in oil tank of transformer 1 heats up expansion, the gas that has of collection exhaust cap 1-1 position to be pressed in the first accumulator 2-1 and to be pooled to peak by insulating oil, be pressed into the second accumulator 2-2 by the expansion of insulating oil by the 4th communicating pipe 6, enter in air eventually through suction wet exhauster 4.
Oil pump, gas in fuel tank is discharged in oil conservator associated working: when oil pump 13 works, not only the insulating oil in oil tank of transformer 1 is directly extracted out, by the 5th communicating pipe 9, the insulating oil in first accumulator 2-1 is extracted out simultaneously, this process can reduce the oil pressure in the first accumulator 2-1, so not only the second accumulator 2-2 of oil conservator 2 can compensate insulating oil, also insulating oil can be pressed onto collection exhaust cap 1-1 in oil tank of transformer 1, if now collect in exhaust cap 1-1 and have gas, gas then can be pressed into third connecting pipe 5, enter the first accumulator 2-1 of oil conservator 2, oil pump 13 can effectively promote that insulating oil circulates, and improve insulating oil cooling effect, the final object realizing gas in discharge fuel tank.
Insulating oil cools: when transformer is in running, open the first fuel tap 12, second fuel tap 14, the 3rd fuel tap 16, insulating oil in oil tank of transformer 1 enters cooler 3 by the import 3-1 of cooler 3 and cools, and cooled insulating oil flows back in oil tank of transformer 1 by the outlet 3-2 of cooler 3, realize the oil cooled object that insulate in fuel tank.
The utility model lab scale effect shows, can under limited installing space condition, realizes the normal mounting of transformer and safe operation and to the compensation supply of insulating oil and effective cooling, achieves the object of the utility model expection.
