Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a transformer cooling system. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. During the operation of the transformer, a large amount of heat is generated between the iron core and the coil. If the heat cannot be dissipated in time, it will affect the normal use of the transformer and even the entire power transmission system. Therefore, a cooling device needs to be set up to cool down the transformer.

[0003] The cooling device of the transformer generally includes a transformer oil tank and a fin radiator arranged outside the transformer oil tank. The transformer is immersed in the transformer oil tank and cooled by the oil in the transformer oil tank. The fin radiator is used to cool down the oil in the transformer oil tank. However, for transformers used in indoor or other non-open environments, the heat dissipation conditions cannot meet the heat generation power of the transformer. Therefore, the fin radiator needs to be placed in a far-open environment. The oil in the transformer oil tank flows into the fin radiator in the open environment through a pipeline, dissipates heat and cools down in the fin radiator, and then flows back into the transformer oil tank to exchange heat with the transformer. For the cooling device with this structure, the pipeline connecting the transformer oil tank and the fin radiator is relatively long, resulting in serious consumption of the oil thermal power of the transformer, slow flow rate of the oil in the pipeline, low heat dissipation efficiency, high temperature rise of the transformer, and seriously affecting the working reliability of the transformer.

[0004] Therefore, it is urgent to propose a transformer cooling system to solve the above technical problems. Summary of the Utility Model

[0005] The utility model provides a transformer cooling system, which can realize the rapid heat dissipation of the transformer, improve the reliability of the transformer operation, and the coolant used to cool down the cooling oil in the transformer oil tank can circulate automatically under the thermosiphon effect, so that the total energy consumption of the transformer cooling system is relatively low.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] A transformer cooling system, comprising:

[0008] A transformer oil tank filled with cooling oil for heat exchange with the transformer body. An oil outlet is provided at the upper part of the transformer oil tank, and an oil return port is provided at the lower part of the transformer oil tank. The oil return port and the oil outlet are connected through a heat exchange pipeline;

[0009] The evaporator includes an evaporation chamber filled with a coolant. A heat exchange pipe passes through the evaporation chamber, and the part of the heat exchange pipe placed in the evaporation chamber is immersed in the coolant. A steam outlet and a liquid return port are provided on the evaporation chamber.

[0010] The condenser includes a condensation chamber with a steam inlet and a liquid outlet provided thereon. The steam inlet is communicated with the steam outlet, and the liquid outlet is communicated with the liquid return port. The coolant in the evaporation chamber absorbs the heat of the cooling oil in the heat exchange pipe and vaporizes into steam.

[0011] Optionally, the top of the evaporation chamber is an inclined roof, and both the steam outlet and the liquid return port are provided on the inclined roof. The height of the steam outlet is higher than that of the liquid return port.

[0012] Optionally, heat dissipation fins are provided on the part of the heat exchange pipe placed in the evaporation chamber.

[0013] Optionally, the condenser is arranged higher than the evaporator. The steam inlet is communicated with the steam outlet through a steam delivery pipe, and the steam delivery pipe is inclined towards the condenser. The liquid outlet is communicated with the liquid return port through a liquid delivery pipe.

[0014] Optionally, both the steam inlet and the liquid outlet are provided at the bottom of the condensation chamber.

[0015] Optionally, the transformer cooling system further includes a mounting rack. The condenser is mounted on the mounting rack, and the condenser is higher than the evaporator through the mounting rack.

[0016] Optionally, a vacuum pumping port is provided at the top of the condensation chamber.

[0017] Optionally, the condensation chamber includes a plurality of interconnected condensation fins, and the plurality of condensation fins are arranged at intervals.

[0019] Optionally, the transformer cooling system further includes a cooling fan arranged opposite to the condensation chamber. The cooling fan is used to dissipate heat from the condensation chamber.

[0020] The beneficial effects of the present utility model:

[0021] The utility model provides a transformer cooling system, which includes a transformer oil tank, an evaporator and a condenser. The cooling oil in the transformer oil tank exchanges heat with the transformer body immersed in the cooling oil, and then the temperature rises. The high-temperature cooling oil with reduced density will rise and enter the heat exchange pipeline from the oil outlet of the transformer oil tank. The high-temperature cooling oil in the heat exchange pipeline exchanges heat with the coolant in the evaporation chamber and then cools down. The cooled cooling oil returns to the transformer oil tank through the oil return port of the transformer oil tank. After absorbing the heat of the cooling oil, the coolant in the evaporation chamber vaporizes into steam, expands in volume, and becomes smaller in density, generating a thermosiphon effect, which enables the steam to automatically enter the condensation chamber. The condensation chamber cools down the hot steam to condense it into coolant, and the coolant returns to the evaporation chamber under the thermosiphon effect. This transformer cooling system utilizes the thermosiphon effect to achieve the self-circulation of the coolant, resulting in a relatively high flow rate of the coolant, improving the heat exchange efficiency between the coolant and the cooling oil, enabling the cooling oil to quickly cool down the transformer body, and enhancing the working reliability of the transformer. Moreover, the circulation of the coolant and the circulation of the cooling oil in the heat exchange pipeline do not need to be realized by a circulation pump, reducing the total energy consumption of this transformer cooling system.

[0022] Due to the relatively fast flow rate of the coolant, this transformer cooling system can also achieve the rapid cooling of the transformer when applied to a transformer working in a non-open environment, improving the working reliability of the transformer. Description of the Drawings

It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only parts related to the present utility model rather than all structures are shown in the drawings.

The first feature being "below", "below the bottom", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal height than the second feature.

[0037] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0038] This embodiment provides a transformer cooling system, which can achieve rapid heat dissipation of the transformer, improve the reliability of the transformer operation, and the coolant used to cool the cooling oil in the transformer oil tank can self-circulate under the thermosiphon effect, making the total energy consumption of this transformer cooling system relatively low.

[0039] Specifically, as Figure 1 shown, this transformer cooling system includes a transformer oil tank 100, an evaporator 200, and a condenser 300.

[0040] Among them, the transformer oil tank 100 is filled with cooling oil for heat exchange with the transformer body 10. An oil outlet 110 is provided at the upper part of the transformer oil tank 100, and an oil return port 120 is provided at the lower part of the transformer oil tank 100. The oil return port 120 and the oil outlet 110 are connected through a heat exchange pipeline 130. The transformer body 10 to be cooled is immersed in the cooling oil in the transformer oil tank 100 to contact and exchange heat with the cooling oil to achieve the purpose of temperature reduction. Moreover, after the cooling oil absorbs the heat of the transformer body 10 and its temperature rises, its density will decrease. The hot cooling oil with a lower density will rise. That is, in the transformer oil tank 100, the hot cooling oil is located at the upper part, and the low-temperature cooling oil is located at the lower part. Therefore, the oil outlet 110 is provided at the upper part of the transformer oil tank 100, and the oil return port 120 is provided at the lower part of the transformer oil tank 100.

[0041] The evaporator 200 includes an evaporation chamber 210. The evaporation chamber 210 is filled with coolant. The heat exchange pipeline 130 passes through the evaporation chamber 210, and the part of the heat exchange pipeline 130 placed in the evaporation chamber 210 is immersed in the coolant. A steam outlet 211 and a liquid return port 212 are provided on the evaporation chamber 210. The hot cooling oil flowing out of the transformer oil tank 100 from the oil outlet 110 will enter the heat exchange pipeline 130 through the inlet of the heat exchange pipeline 130. When the hot cooling oil flows through the part of the heat exchange pipeline 130 placed in the evaporation chamber 210, it will exchange heat with the coolant in the evaporation chamber 210 to reduce the temperature. The cooled low-temperature cooling oil after heat exchange will flow back into the transformer oil tank 100 from the oil return port 120 through the outlet of the heat exchange pipeline 130. This self-circulation of the cooling oil is spontaneous and does not require energy consumption, reducing the energy consumption of the transformer cooling system.

[0042] The condenser 300 includes a condensation chamber 310, on which a steam inlet 311 and a liquid outlet 312 are provided. The steam inlet 311 is communicated with the steam outlet 211, and the liquid outlet 312 is communicated with the liquid return port 212. The coolant in the evaporation chamber 210 absorbs the heat of the cooling oil in the heat exchange pipe 130 and vaporizes into steam. After vaporizing into steam, the volume expands and the density becomes smaller, generating a thermosiphon effect, so that the steam can automatically enter the condensation chamber 310. The condensation chamber 310 cools the hot steam to condense it into a coolant, and the coolant will return to the evaporation chamber 210 under the thermosiphon effect.

[0043] The transformer cooling system provided by this embodiment utilizes the thermosiphon effect to realize the self-circulation of the coolant, so that the flow rate of the coolant is relatively high, improving the heat exchange efficiency between the coolant and the cooling oil, enabling the cooling oil to quickly cool down the transformer body 10, and improving the working reliability of the transformer. Moreover, the circulation of the coolant and the circulation of the cooling oil in the heat exchange pipe 130 do not need to be realized by a circulation pump, reducing the total energy consumption of the transformer cooling system. In addition, due to the relatively fast flow rate of the coolant, when the transformer cooling system is applied to a transformer working in a non-open environment, it can also realize the rapid cooling of the transformer, improving the working reliability of the transformer.

[0044] It should be noted that the thermosiphon effect refers to the process of using heating to partially vaporize a liquid to form a gas-liquid mixture with a smaller density, and using the density difference as the driving force to complete the circulation. Therefore, the thermosiphon effect is also called thermocyclic motion.

[0045] Furthermore, as Figure 1 and Figure 2 shown, the top of the evaporation chamber 210 is an inclined top 213. The steam outlet 211 and the liquid return port 212 are both arranged on the inclined top 213, and the height of the steam outlet 211 is higher than that of the liquid return port 212. Since the coolant will automatically rise after vaporizing into steam, setting the steam outlet 211 on the inclined top 213 at the top of the evaporation chamber 210 and on the higher side in the height direction of the inclined top 213 is beneficial to the aggregation of steam, making the process of steam flowing out of the evaporation chamber 210 and entering the condensation chamber 310 smoother.

[0046] Optionally, the angle between the inclined top 213 and the horizontal plane is greater than or equal to 15°. With such a setting, the smoothness of steam flow can be further improved.

[0047] Furthermore, continue to refer to Figure 1 and Figure 2, heat dissipation fins 220 are provided on the part of the heat exchange pipe 130 placed in the evaporation chamber 210. By providing the heat dissipation fins 220, the heat exchange area between the heat exchange pipe 130 and the coolant can be increased, so as to improve the heat exchange efficiency between the coolant and the cooling oil. In this way, the heat exchange efficiency between the cooling oil and the transformer body 10 can be improved, the reliability of the temperature reduction of the transformer body 10 can be improved, and further the reliability of the transformer operation can be improved.

[0048] Optionally, the heat dissipation fins 220 can be spiral heat dissipation fins or fin-type heat dissipation fins, etc., and can be set according to actual needs. The present application does not make specific limitations.

[0049] Furthermore, continue to refer to Figure 1 , the condenser 300 is arranged higher than the evaporator 200, the steam inlet 311 and the steam outlet 211 are connected through a steam delivery pipe 400, the steam delivery pipe 400 is arranged obliquely in the direction of the condenser 300, and the liquid outlet 312 and the liquid return port 212 are connected through a liquid delivery pipe 500. By arranging the condenser 300 higher than the evaporator 200 and arranging the steam delivery pipe 400 obliquely in the direction of the condenser 300, the upward moving steam can be assisted, so that the steam can smoothly move into the condensation chamber 310 during the upward aggregation process, and further improve the circulation efficiency of the coolant between the evaporation chamber 210 and the condensation chamber 310.

[0050] Optionally, the angle a between the steam delivery pipe 400 and the horizontal plane is greater than or equal to 15°. With such a setting, the smoothness of the steam flow can be further improved.

[0051] Optionally, continue to refer to Figure 1 , valves can be provided at the steam outlet 211, the steam inlet 311, the liquid outlet 312 and the liquid return port 212, and the opening and closing of the steam outlet 211, the steam inlet 311, the liquid outlet 312 and the liquid return port 212 can be controlled through the respective corresponding valves.

[0052] Furthermore, as Figure 1 and Figure 3 shown, both the steam inlet 311 and the liquid outlet 312 are arranged at the bottom of the condensation chamber 310. By arranging the steam inlet 311 at the bottom of the condensation chamber 310, the movement distance of the steam between the evaporation chamber 210 and the condensation chamber 310 is the shortest, and the circulation efficiency of the coolant is further improved. By arranging the liquid outlet 312 at the bottom of the condensation chamber 310, it is convenient for the coolant to flow into the evaporation chamber 210 under the action of its own gravity.

[0053] Optionally, continue to refer to Figure 1, the transformer cooling system further includes a mounting bracket 600, and the condenser 300 is mounted on the mounting bracket 600. By providing the mounting bracket 600, the condenser 300 can be elevated so that the condenser 300 is disposed higher than the evaporator 200.

[0054] Further, in this embodiment, the mounting bracket 600 includes a plurality of columns, and the condenser 300 is mounted on the tops of the plurality of columns.

[0055] Further, as Figure 3 shown, a vacuum extraction port 313 is provided at the top of the condensation chamber 310. The vacuum extraction port 313 is communicated with a vacuum extraction device (not shown in the figure). A vacuum extraction valve 314 is provided at the vacuum extraction port 313. The vacuum extraction valve 314 is used to control the opening and closing of the vacuum extraction port 313. When it is necessary to evacuate the condensation chamber 310, start the vacuum extraction device and open the vacuum extraction valve 314; when it is not necessary to evacuate the condensation chamber 310, just close the vacuum extraction device and the vacuum extraction valve 314. The condensation chamber 310 can be evacuated by the vacuum extraction device. After evacuation, the pressures in the condensation chamber 310 and the evaporation chamber 210 communicated with the condensation chamber 310 will both decrease. The decrease in pressure can lower the boiling point of the coolant, making it easier for the coolant to vaporize into steam. In this way, it is beneficial to improve the circulation efficiency of the coolant and can also be applicable to more different coolants, with high universality. By providing the vacuum extraction valve 314 to control the opening and closing of the vacuum extraction port 313, it can be avoided that air in the external environment enters the condensation chamber 310 through the vacuum extraction device and the vacuum extraction port 313 when evacuation is not required, improving the reliability of the vacuum environment in the condensation chamber 310. In addition, through evacuation, the circulation pressure of the coolant can be made less than the circulation pressure of the cooling oil. If the heat exchange pipeline 130 leaks, the cooling oil will flow into the coolant due to the large pressure, while the coolant will not flow into the cooling oil, effectively avoiding the occurrence of the situation that the insulation performance of the transformer body 10 decreases or even short-circuits due to the coolant flowing into the cooling oil, and improving the reliability of the transformer operation.

[0056] Optionally, in this embodiment, the coolant is water, which has a low cost and is easily obtainable. In other embodiments, the coolant can also be set to others, which can be set according to actual needs, and the present application does not make specific limitations.

[0057] Further, continue to refer to Figure 3 , a pressure detection member 315 can be provided at the top of the condensation chamber 310 to monitor the pressure in the condensation chamber 310 through the pressure detection member 315. By providing the pressure detection member 315, it is possible to determine whether there is a leakage fault between the condenser 300 and the evaporator 200 according to the detected pressure value in the condensation chamber 310. It is also possible to control the operation of the vacuum extraction device according to the obtained pressure information in the condensation chamber 310 to ensure that the pressure value in the condensation chamber 310 can meet the requirements.

[0058] Further, as Figure 4 shown, in a possible embodiment, there are multiple condensation chambers 310, and the multiple condensation chambers 310 are arranged at intervals. There are multiple steam outlets 211 and multiple liquid return ports 212, and the steam outlets 211 and the liquid return ports 212 are arranged in one-to-one correspondence with the condensation chambers 310. By providing multiple condensation chambers 310, the heat exchange area between the condensation chambers 310 and the outside air can be increased, thereby improving the condensation efficiency of the condenser 300.

[0059] It can be understood that the multiple condensation chambers 310 form a structure similar to a plate heat exchanger.

[0060] Optionally, in another possible embodiment, the condensation chamber 310 includes multiple interconnected condensation fins, and the multiple condensation fins are arranged at intervals. By providing that the condensation chamber 310 includes multiple interconnected condensation fins, the heat exchange area between the condensation chamber 310 and the outside air can be increased, thereby improving the condensation efficiency of the condenser 300. Moreover, by providing that the multiple condensation fins are interconnected, only one steam inlet 311 and one liquid outlet 312 need to be provided for the condensation chamber 310, and only one steam outlet 211 and one liquid return port 212 need to be provided for the evaporation chamber 210, simplifying the structure of the transformer cooling system.

[0061] Further, continue to refer to Figure 1 and Figure 4 , the transformer cooling system further includes a cooling fan 700, and the cooling fan 700 is disposed opposite to the condensation chamber 310. The cooling fan 700 is used to dissipate heat from the condensation chamber 310. By providing the cooling fan 700, the flow rate of the air around the condensation chamber 310 can be increased, thereby improving the condensation efficiency of the condenser 300.

[0062] Optionally, the cooling fan 700 can be provided as one or multiple, and can be set according to actual needs, and the present application does not make specific limitations.

[0063] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
