Description
The utility model belongs to the cooling device that a kind of power transformer cold oil is used.
During transformer work, need to use oil that it is cooled off.Transformer is carried out cooled oil have heat, need cool off, then for recycling heat content oil.Cooling device generally has two kinds of versions, and a kind of is air-cooled, and a kind of is water-cooled.
Fig. 1 is the structural front view of the present air cooling equipment that uses, one casing 1 is arranged, the casing internal upper part has upper spacer 2, constitute oil suction chamber 3 on it, on the wall of oil suction chamber chamber oil-in 4 is arranged, lower clapboard 5 is arranged at the bottom in the casing, constitutes under it oil pocket 6, and going out on the wall of oil pocket chamber has oil-out 7, the middle part is a cooling chamber 8 in the casing, forced air cooled tube 9 is arranged in the cooling chamber, the forced air cooled tube two ends respectively with upper spacer, lower clapboard connects, the two ends mouth of pipe of forced air cooled tube respectively with oil suction chamber, going out oil pocket communicates, it is air inlet 10 that one side chamber wall of cooling chamber 8 has accent, on the chamber wall relative accent 11 is arranged, connect mozzle 12 on the accent 11, blower fan 13 is arranged in this mozzle with this air inlet.High temperature oil is entered by oil-in, when oil suction chamber is flowed through forced air cooled tube, because of the effect of blower fan 13 runnings, in cooling chamber, form high wind stream,, the heat content oil in the forced air cooled tube of flowing through is cooled off by the heat conduction of forced air cooled tube tube wall, cooled oil is flowed out by the oil-out that goes out on the oil pocket, for recycling.
The air cooling equipment of existing transformer cold oil, better cooling effect is arranged, but its use is a kind of single air cooling medium, in actual the use, except that cooling effectiveness is subjected to certain limitation, when blower fan breaks down and often have a power failure because of the station-service working power, air cooling equipment then loses refrigerating function, make the running of transformer have to stop, transformer is out of service, will produce adverse consequences to whole electrical network or big capacity and equipment operation that can not sudden power.
The purpose of this utility model provides the compound cooling device that a kind of power transformer cold oil is used, improve cooling effectiveness, or when wherein a kind of coolant can not or be not used in cooling, changeable another kind of coolant still can make it have corresponding or certain refrigerating function, and power transformer works on or the sub-load continuous service to keep.
The technical solution of the utility model is, a casing is arranged, and the casing internal upper part has upper spacer, constitutes oil suction chamber on it, on the wall of oil suction chamber chamber oil-in arranged; Lower clapboard is arranged at the bottom in the casing, constitutes under it oil pocket, and going out on the wall of oil pocket chamber has oil-out; The middle part is a cooling chamber in the casing, and forced air cooled tube is arranged in the cooling chamber, and the forced air cooled tube two ends are connected with described upper spacer, lower clapboard respectively, the two ends mouth of pipe respectively with described oil suction chamber, go out oil pocket and communicate; One side chamber wall of described cooling chamber is that accent is an air inlet, on the chamber wall relative accent is arranged with this air inlet, connect mozzle on this accent limit wall, blower fan is set in the mozzle, and during fan operation, cold wind is entered by air inlet, through cooling chamber, discharge by the mozzle mouth of pipe, make to form high wind stream in the cooling chamber, the heat content oil in the forced air cooled tube of flowing through is cooled off.Described content is with existing air-cooling device.The improved content of the utility model is, at the oil suction chamber of existing air cooling equipment with go out in arbitrary oil pocket in the oil pocket water cooling tube is set, the two ends of water cooling tube pass two chamber walls of oil pocket respectively, when cold water is flowed through water cooling tube, by the heat conduction of water cooling tube tube wall, the oil in the oil pocket of flowing through is cooled off.High temperature oil from cooling transformer is entered by oil-in, in the process of discharging by oil-out, can be through air-cooled, water-cooled combined type cooling, and when a kind of coolant is not wherein done the time spent, can be by another kind of coolant cooling.
Because wooden utility model is set to air-cooled, water-cooled composite structure, has following characteristics:
1. all do the time spent when air-cooled, water-cooled medium, can improve cooling effectiveness, be particularly useful for the big oil cooling of heat content but.Also can be air-cooled is that main, water-cooled is auxilliary, or water-cooled be main, air-cooled be the function mode of assisting.
2. a kind of coolant is done the time spent in, the water-cooled medium air-cooled when only needing, can select any by the mode of switching, realize cooling off by turns, can guarantee the reliability of cooling performance, especially when wherein a kind of drive unit of coolant breaks down, cool off by switching another kind of coolant, still can satisfy power transformer and continue operation.
3. when drive unit air-cooled, the water-cooled medium all can not turn round for some reason, can utilize water-head, make the cooling water water cooling tube of still can flowing through, keep certain refrigerating function, satisfy the power transformer sub-load and continue operation by the elevated tank of other supporting setting.
Fig. 1 is the structural front view of existing power transformer cold oil air cooling equipment, and Fig. 2 is a structural front view of the present utility model.
Embodiment.Referring to Fig. 2, be box typed structure, casing 1 internal upper part is provided with upper spacer 2, constitute oil suction chamber 3 on it, establish oil-in 4 on the wall of oil suction chamber chamber, the bottom is provided with lower clapboard 5 in the casing, constitute under it and oil pocket 6, go out on the wall of oil pocket chamber to set out hydraulic fluid port 7, the casing middle part is a cooling chamber 8, and forced air cooled tube 9 is set in the cooling chamber, the forced air cooled tube two ends respectively with upper spacer, lower clapboard connects, connecting portion should satisfy the antiseep requirement, the two ends mouth of pipe respectively with oil suction chamber, go out oil pocket and communicate, a side chamber wall of cooling chamber 8 is arranged to accent, it is air inlet 10, on the chamber wall relative with this air inlet accent 11 is set, connects mozzle 12 on the limit wall of this accent, the blower fan 13 that is located in the mozzle is the induced air type structure.In this example, water cooling tube 14 is located at out in the oil pocket 6, and the water cooling tube two ends pass out oil pocket chamber wall respectively, both contacts site should satisfy the antiseep requirement, in actual the use, the water cooling tube two ends mouth of pipe joins with upper and lower conduit respectively, and water cooling tube also can be the same structure form and is located in the oil suction chamber 3.The forced air cooled tube 9 that is located in the cooling chamber calculates according to actual needs with the quantity and the diameter that are located at out the water cooling tube in the oil pocket.At oil suction chamber or go out water cooling tube is set in the oil pocket, when air-cooled and the drive unit water-cooled medium break down, can utilize water-head by the elevated tank of other supporting setting, current are cooled off heat content oil through water cooling tube, continue operation to satisfy the power transformer sub-load.
