Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, in particular to a transformer energy-saving heat dissipation device. Background Art

[0002] During the operation of a transformer, a large amount of heat is generated. If it cannot be dissipated in a timely and effective manner, it will cause the internal temperature of the transformer to rise, thereby affecting its performance and lifespan, and even triggering safety accidents. Therefore, it is particularly important to develop an efficient and energy-saving transformer heat dissipation device.

[0003] Currently, in existing transformer heat dissipation equipment, such as the patent with the authorization announcement number CN212161505U, this utility model discloses an energy-saving radiator for an oil-immersed transformer, including a transformer body. An oil inlet pipe is fixedly installed at the top of the transformer body, and a ventilation pipe is fixedly connected to one side of the transformer body. A heat dissipation mechanism is installed inside the ventilation pipe. The heat dissipation mechanism includes a heat dissipation fan, and the heat dissipation fan is connected to the inside of the ventilation pipe. Two clamping grooves are respectively fixedly connected to both sides of the inner wall of the ventilation pipe, and two clamping blocks are clamped and connected inside the clamping grooves. One side of the clamping block is fixedly connected to a connecting plate.

[0004] However, it is found during the use of this equipment that the heat dissipation and temperature reduction effect of this equipment on the transformer is poor, and it is not convenient to use rainwater to cool the transformer, increasing the energy consumption of the equipment and reducing the energy-saving and environmental protection effect. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a transformer energy-saving heat dissipation device that improves the heat dissipation and temperature reduction effect of electrical components inside the transformer body, improves the utilization rate of rainwater, and improves the energy-saving effect.

[0006] An energy-saving heat dissipation device for a transformer of the present utility model includes a transformer body. An oil discharge port is provided at the lower part of the transformer body, and an oil inlet is provided at the upper part of the transformer body. It also includes a protection device, a heat exchange device, a cooling device, a first storage tank, a collection hopper, a delivery pipe, and a second storage tank. The collection hopper is connected and arranged at the top end of the first storage tank. A protection device is provided on the collection hopper for protecting the opening of the first storage tank. The input end of the delivery pipe is connected to the collection hopper, and the output end of the delivery pipe is connected to the second storage tank. The second storage tank is installed on the upper part of the outer wall of the first storage tank, and the bottom of the second storage tank is connected to the first storage tank through a pipeline. A heat exchange device is arranged in the first storage tank for cooling the transformer body by heat dissipation. The first storage tank is connected to the cooling device, and the cooling device is used to cool the water in the first storage tank. Rainwater is collected through the collection hopper, and the collected rainwater is stored in the first storage tank. When the rainwater in the first storage tank is full, the rainwater overflows to the inside of the second storage tank through the delivery pipe, so that the second storage tank stores the rainwater. When the water volume in the first storage tank evaporates and decreases, the first storage tank is replenished with water from the second storage tank. The heat exchange device extracts the insulating oil in the transformer body and circulates it through the first storage tank, so that the insulating oil exchanges heat with the rainwater in the first storage tank, and the rainwater cools the insulating oil, thereby improving the heat dissipation and cooling effect of the electrical components in the transformer body, improving the utilization rate of rainwater, and improving the energy-saving effect.

[0007] Preferably, the cooling device includes a bracket, two groups of first delivery boxes, multiple groups of first heat exchange pipes, a first pump body, a fan, and a solar panel. The two groups of first delivery boxes are respectively installed at the upper and lower parts of the inner side wall of the bracket. The upper and lower ends of the multiple groups of first heat exchange pipes are respectively connected to the two groups of first delivery boxes. The input end of the first pump body is connected to the first storage tank, and the output end of the first pump body is connected to the lower first delivery box. The upper first delivery box is connected to the first storage tank. The fan is installed on the outer side wall of the bracket, and the solar panel is installed at the top end of the bracket. The rainwater in the first storage tank is extracted by the first pump body, and the extracted rainwater is delivered to the multiple groups of first heat exchange pipes through the lower first delivery box. Then, the multiple groups of first heat exchange pipes return the rainwater to the first storage tank through the upper first delivery box. The fan blows air on the multiple groups of first heat exchange pipes to cool the multiple groups of first heat exchange pipes by air cooling. After the multiple groups of first heat exchange pipes are cooled, the rainwater flowing inside is cooled, so that the cooled rainwater flows back to the first storage tank to cool the heat exchanger, improving the heat dissipation and cooling effect of the heat exchanger on the transformer body. The solar panel supplies auxiliary power to the fan, reducing the power consumption of the fan and improving the energy-saving effect of the device.

[0008] Preferably, the protection device includes a sealing plate, a support rod, a spring and a sealing ring. The sealing ring is installed on the inner side wall of the collection hopper. The sealing plate is slidably installed up and down inside the support rod. The top end of the sealing plate contacts the bottom end of the sealing ring. The support rod is slidably installed up and down at the bottom of the collection hopper. The top end of the support rod is connected to the bottom end of the sealing plate. The spring is sleeved on the outer side wall of the support rod in a matching manner. When rainwater enters the collection hopper, the weight of the rainwater presses the sealing plate to move downward, so that the rainwater enters the first storage tank through the gap opened between the sealing plate and the sealing ring. When the rainwater at the top end of the sealing plate decreases, the spring supports the sealing plate to move upward and contact the bottom end of the sealing ring, so that the sealing plate and the sealing ring close the opening of the collection hopper, reduce the evaporation waste of the rainwater in the first storage tank, and improve the energy-saving effect.

[0009] Preferably, the heat exchange device includes a second delivery tank, second heat exchange pipes and a second pump body. Two groups of second delivery tanks are installed on the inner side wall of the first storage tank. The upper and lower ends of multiple groups of second heat exchange pipes are respectively communicated with the two groups of second delivery tanks. The input end of the second pump body is communicated with the oil discharge port of the transformer body, and the output end of the second pump body is communicated with the lower second delivery tank. The upper second delivery tank is communicated with the oil inlet of the transformer body. The second pump body extracts and transports the insulating oil in the transformer body to the lower second delivery tank. The insulating oil is transported to the upper second delivery tank through multiple groups of second heat exchange pipes and then flows back into the transformer body. The rainwater in the first storage tank cools the multiple groups of second heat exchange pipes, so that the multiple groups of second heat exchange pipes cool the insulating oil flowing inside through heat conduction, thereby improving the heat dissipation and cooling effect and cooling efficiency of the transformer body.

[0010] Preferably, it further includes multiple groups of guide plates, and the multiple groups of guide plates are installed on the inner side wall of the first storage tank in a staggered manner. The rainwater is guided and transported through the multiple groups of guide plates to improve the flow contact effect between the rainwater and the multiple groups of second heat exchange pipes and improve the cooling effect of the multiple groups of second heat exchange pipes.

[0011] Preferably, it further includes a one-way valve, and the one-way valve is connected in series on the delivery pipe. By setting the one-way valve, the protection effect of the delivery pipe is improved, and the situation that the rainwater in the second storage tank evaporates through the delivery pipe is reduced.

[0012] Preferably, it further includes a filter screen, and the filter screen is installed on the inner side wall of the collection hopper. The rainwater entering the collection hopper is filtered through the filter screen to improve the cleanliness of the rainwater.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: Rainwater is collected through a collecting hopper and stored in the first storage tank. When the first storage tank is full of rainwater, the rainwater overflows into the second storage tank through a conveying pipe, so that the second storage tank stores the rainwater. When the water volume in the first storage tank decreases due to evaporation, the second storage tank replenishes water to the first storage tank. The heat exchange device extracts the insulating oil in the transformer body and circulates it through the first storage tank, so that the insulating oil exchanges heat with the rainwater in the first storage tank, and the rainwater cools the insulating oil, thereby improving the heat dissipation and cooling effect of the electrical components in the transformer body, improving the utilization rate of rainwater, and improving the energy-saving effect.
