Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer casing with a heat dissipation mechanism. Background Art

[0002] A transformer is an electrical device that uses electromagnetic induction to change AC voltage. It is mainly composed of an iron core and windings. Its main functions include realizing voltage conversion, isolating circuits, and matching impedances. In power systems, transformers are widely used in power transmission, substation, and distribution to ensure efficient and stable transmission and distribution of electrical energy. In order to ensure the service life and safety performance of the transformer, a heat dissipation mechanism is usually set on the transformer casing;

[0003] In the prior art, the heat dissipation mechanism of the transformer housing generally includes natural cooling, forced air cooling, water circulation cooling, etc. When the transformer starts working, the heat dissipation mechanism starts working at the same time to continuously dissipate heat for the transformer;

[0004] However, the transformer needs to be within a certain temperature range to perform at its best. When the transformer starts working, it will start to heat up, and the continuously working heat dissipation mechanism will affect the heating rate of the transformer, thereby affecting the transformer's operating performance. When the weather temperature is low, the continuous heat dissipation mechanism is difficult to adjust the heat dissipation intensity according to temperature changes, which can easily cause the transformer's operating temperature to be too low, thereby affecting the transformer's working performance.

[0041] Embodiment 1:

[0042] The present invention proposes a transformer housing with a heat dissipation mechanism. When in use, the transformer housing 1 is covered above the transformer, so that the bottom of the transformer housing 1 is connected to the transformer base, and the heat transfer oil is filled into the inside of the transformer housing 1 through the filling port of the transformer housing 1, and the coolant is filled into the inside of the water tank 4 through the filling port of the water tank 4;

[0043] When the transformer starts to work, the pump group 41 draws out the coolant in the water tank 4, and flows into the transformer housing 1 through the circulating water pipe 42 and the U-shaped pipe 421, and then flows back into the water tank 4, so that the coolant and the heat transfer oil complete the heat exchange. At the same time, the heat generated by the transformer operation is transferred to the side fins 3 on both sides through the heat transfer oil and the transformer housing 1. When the coolant flows through the installation bin 43, the coolant impacts the surface of the dial plate 61 to drive the rotating shaft 6 to rotate, and the rotating shaft 6 drives the fan wheel 62 to rotate. The fan wheel 62 rotates to form an airflow blowing toward the side fins 3, thereby realizing accelerated heat dissipation of the side fins 3.

[0044] The fan wheel 62 is driven to rotate by arranging the circulation of the coolant, so that the fan wheel 62 drives the air flow to blow toward the side fins 3, thereby accelerating the heat dissipation of the side fins 3 and realizing the heat dissipation of the transformer.

[0045] Embodiment 2:

[0046] On the basis of the first embodiment, when the outside temperature is high and the operating temperature of the transformer is too high, the temperature of the coolant inside the circulating water pipe 42 gradually increases. At this time, the expansion airbag 46 expands due to the heat and drives the lifting column 47 to rise. When the lifting column 47 rises to a certain height, the support rod 471 pushes the lifting rod 54 to rise, and the lifting rod 54 drives the end of the connecting rod 53 away from the flip plate 5 to rise, thereby driving the flip plate 5 to flip, so that a vent is formed between the flip plates 5 and the flip plates 5. At the same time, the lifting rod 54 triggers the travel switch 232. At this time, the exhaust fan 25 rotates and brings air flow through the vent between the flip plates 5 and the flip plates 5 into the interior of the bottom shell 23, and then flows through the top fin 233 and is discharged through the exhaust pipe 24, thereby realizing secondary heat dissipation of the transformer. When the temperature of the transformer drops, the expansion airbag 46 contracts and drives the lifting column 47 to descend, so that the flip plate 5 is closed;

[0047] The expansion and contraction of the expansion bag 46 is controlled by the temperature of the transformer, driving the opening and closing of the flip plate 5. When the temperature of the transformer is low, the expansion bag 46 is in a contracted state, and the flip plate 5 is in a closed state. The heat dissipation of the transformer is carried out in the manner described in Example 1. When the temperature of the transformer is too high, the expansion of the expansion bag 46 drives the flip plate 5 to open, and at the same time the exhaust fan 25 drives the airflow to flow through the top fin 233, realizing secondary heat dissipation of the transformer, so that the transformer can adjust the heat dissipation intensity according to the external temperature changes, so that the transformer is in a specified operating temperature range, thereby ensuring the operating performance of the transformer.

[0048] Embodiment three:

[0049] On the basis of the second embodiment, by arranging the rainwater pipe 32 inside the side fin 3, when it rains, the rainwater flows to the water outlet 22 through the arc-shaped top cover 21, and then flows to the filter cartridge 63 through the first water guide plate 321, and the filter cartridge 63 is in a rotating state driven by the rotating shaft 6. At this time, the rainwater flowing to the filter cartridge 63 is dispersed under the collision of the rotation of the filter cartridge 63, and then floats to the side fin 3 under the blowing of the fan wheel 62, so as to realize the cooling of the side fin 3, reduce the possibility of the transformer temperature being too high, thereby reducing the number of times the secondary heat dissipation is turned on, and reducing the energy loss;

[0050] At the same time, when the filter cartridge 63 is rotating, the scraper 34 scrapes the surface of the filter cartridge 63 to remove impurities carried in the rainwater from the surface of the filter cartridge 63 to avoid clogging of the filter cartridge 63 .

[0051] Working principle: The transformer housing with a heat dissipation mechanism proposed by the present invention, when in use, the transformer housing 1 is covered above the transformer, so that the bottom of the transformer housing 1 is connected to the transformer base, and the heat transfer oil is added to the inside of the transformer housing 1 through the filling port of the transformer housing 1, and the coolant is added to the inside of the water tank 4 through the filling port of the water tank 4. When the transformer starts to work, the pump group 41 draws out the coolant in the water tank 4, and flows into the inside of the transformer housing 1 through the circulating water pipe 42 and the U-shaped pipe 421, and then flows back to the inside of the water tank 4. , so that the coolant and the heat transfer oil complete the heat exchange, and at the same time, the heat generated by the transformer is transferred to the side fins 3 on both sides through the heat transfer oil and the transformer housing 1. When the coolant flows through the installation bin 43, the coolant impacts the surface of the dial plate 61 to drive the rotating shaft 6 to rotate, and the rotating shaft 6 drives the fan wheel 62 to rotate. The fan wheel 62 rotates to form an airflow to blow to the side fins 3, thereby accelerating the heat dissipation of the side fins 3. When the external temperature is high and the operating temperature of the transformer is too high, the temperature of the coolant inside the circulating water pipe 42 gradually increases. At this time, the expansion airbag 46 is heated and expanded to drive the lifting column 47 rises. When the lifting column 47 rises to a certain height, the supporting rod 471 pushes the lifting rod 54 to rise. The lifting rod 54 drives the end of the connecting rod 53 away from the flip plate 5 to rise, thereby driving the flip plate 5 to flip, so that a vent is formed between the flip plates 5 and the flip plates 5. At the same time, the lifting rod 54 triggers the travel switch 232. At this time, the exhaust fan 25 rotates and brings air flow through the vent between the flip plates 5 and the flip plates 5 into the interior of the bottom shell 23, and then flows through the top fin 233 and is discharged through the exhaust pipe 24, thereby realizing the secondary heat dissipation of the transformer. When the temperature of the transformer is lowered, , the inflatable airbag 46 contracts and drives the lifting column 47 to descend, so that the flip plate 5 is closed. When it rains, rainwater flows to the drain port 22 through the arc-shaped top cover 21, and then flows to the filter cartridge 63 through the first water guide plate 321. Driven by the rotating shaft 6, the filter cartridge 63 is in a rotating state. At this time, the rainwater flowing to the filter cartridge 63 is dispersed under the rotation collision of the filter cartridge 63, and then floats to the side fin 3 under the blowing of the fan wheel 62, thereby cooling the side fin 3 and reducing the possibility of excessive temperature of the transformer, thereby reducing the number of times the secondary heat dissipation is opened and reducing energy loss.
