Description

Technical Field

[0001] The utility model relates to the technical field of oil storage cabinets, in particular to a transformer oil level compensation cooler. Background Art

[0002] The oil conservator is commonly known as the oil pillow. It is a cylindrical container placed horizontally above the oil tank and connected to the oil tank of the transformer by a pipeline. When the transformer oil expands due to heat, the oil flows from the oil tank to the oil conservator. When the transformer oil contracts due to cold, the oil flows from the oil conservator to the oil tank.

[0003] In actual use, traditional capsule oil conservators and metal corrugated oil conservators cannot dissipate heat for transformer oil. Transformer heat dissipation is limited to the radiator fins. In addition, since the traditional oil conservator has only one connecting pipe connected to the transformer oil tank, it is easy to cause incomplete circulation of hot and cold oil and similar problems. Utility Model Content

[0004] In order to solve the problem of transformer oil heat dissipation in the prior art, the utility model proposes a transformer oil level compensating cooler. The transformer oil level compensator is designed with upper and lower oil collecting boxes by utilizing the liquid heat exchange principle. The oil inlet pipe and the oil outlet pipe are independent pipelines, which optimizes the traditional oil storage cabinet that has only one connecting pipe connected to the transformer oil tank.

[0005] A transformer oil level compensation cooler comprises a lower oil collecting box and an upper oil collecting box, wherein the upper oil collecting box is provided with an oil inlet pipe on a side surface close to the center of the transformer, and the lower oil collecting box is provided with an oil outlet pipe on a side surface away from the center of the transformer, a corrugated pipe is provided between the lower oil collecting box and the upper oil collecting box, and the bottom of the lower oil collecting box is fixedly connected to a support rod, and the bottom of the support rod is fixedly connected to the top surface of the transformer.

[0006] Furthermore, the oil inlet pipe and the upper oil collecting box, the bellows, the lower oil collecting box and the oil outlet pipe are interconnected. When the insulating oil needs to enter the transformer, it can enter the upper oil collecting box through the oil inlet pipe, then pass through the bellows and the lower oil collecting box, and finally return to the inside of the transformer through the oil outlet pipe. The interconnected structure ensures that the oil flows smoothly between the various components, thereby effectively realizing the functions of circulating cooling and oil level compensation of the transformer oil.

[0007] Furthermore, a conduit 1 is passed through and fixedly connected to a side surface of the oil inlet pipe away from the upper oil collecting box. The conduit 1 is passed through and fixedly connected to the top surface of the transformer on a side surface away from the upper oil collecting box. The top of the transformer is connected to the oil inlet pipe, and oil circulation at the top of the transformer is achieved through the conduit 1, ensuring that the top of the transformer can also participate in the oil circulation process, thereby improving the oil circulation efficiency inside the entire transformer and further achieving uniform distribution of oil temperature and balance of oil level.

[0008] Furthermore, a second conduit is passed through and fixedly connected to a surface of a side of the oil outlet pipe away from the lower oil collecting box, and a second conduit is passed through and fixedly connected to a side surface of the transformer away from the lower oil collecting box. Oil circulation on the side of the transformer is achieved through the second conduit, which can help ensure that different parts of the transformer can participate in the oil circulation, thereby effectively improving the circulation efficiency of the oil and promoting the uniform distribution of the oil temperature and the balance of the oil level inside the transformer.

[0009] Furthermore, the bellows are provided in eight groups, each group having three bellows. By increasing the flexibility and efficiency of the oil circulation system, the paths and channels of the oil circulation can be increased, thereby improving the flow velocity and circulation efficiency of the oil in the bellows. The heat exchange surface area between the oil and the external environment can also be increased, thereby promoting the cooling effect of the transformer oil and ensuring the stability and reliability of the transformer during operation.

[0010] Furthermore, the overall shape of the support rod is Y-shaped and is made of stainless steel. Stainless steel has good corrosion resistance and can be used for a long time in a humid or corrosive environment without rusting or corroding, thereby extending the service life of the support rod. The Y-shape can provide good supporting effect, durability and aesthetics.

[0011] The difference from the prior art is that the beneficial effects of this application are:

[0012] (1) The transformer oil level compensator cooler participates in the oil level compensation work through multiple stainless steel bellows at the same time. The hollow area can assist the transformer in heat dissipation under natural environment. The transformer oil level compensator is designed with upper and lower oil collecting boxes based on the principle of liquid heat exchange to achieve the effect of independent oil inlet and outlet pipes to prevent incomplete circulation of hot and cold oil.

The conduit 300 is connected between the top of the transformer and the oil inlet pipe 400. The oil circulation at the top of the transformer is realized through the conduit 300, ensuring that the top of the transformer can also participate in the oil circulation process, thereby improving the oil circulation efficiency inside the entire transformer and further realizing the uniform distribution of oil temperature and the balance of oil level. The oil outlet pipe 500 is away from the lower oil collecting box A conduit 200 is passed through and fixedly connected to one side surface of the box 800. The conduit 200 passes through and is fixedly connected to the side surface of the transformer away from the lower oil collecting box 800. The oil circulation on the side of the transformer is realized through the conduit 200, which can help ensure that different parts of the transformer can participate in the oil circulation, thereby effectively improving the circulation efficiency of the oil and promoting the uniform distribution of the oil temperature and the balance of the oil level inside the transformer. A bellows 700 is arranged between the lower oil collecting box 800 and the upper oil collecting box 600. The bellows 700 are arranged in eight groups, each group having three bellows. By increasing the flexibility and efficiency of the oil circulation system, the path and channel of the oil circulation can be increased. , thereby improving the flow rate and circulation efficiency of the oil in the bellows 700, and can also increase the heat exchange surface area between the oil and the external environment, promote the cooling effect of the transformer oil, and ensure the stability and reliability of the transformer during operation. The bottom of the lower oil collecting box 800 is fixedly connected with a support rod 900. The overall shape of the support rod 900 is Y-shaped, and it is made of stainless steel.
