Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer cooling, in particular to a dry-wet separation type transformer cooling device. Background Art
[0002] The dry-wet separation transformer is a specially designed transformer. Its main feature is that an isolation area is set between the high-voltage side and the low-voltage side to isolate the insulating medium on the high-voltage side from the insulating medium on the low-voltage side to avoid cross-contamination of the insulating oil during operation. The dry-wet separation transformer is usually used for voltage conversion and insulation protection of the power system. Its design can effectively isolate the insulating medium on the high-voltage side and the low-voltage side, reducing the possibility of insulation failure during operation of the transformer. Since it can effectively isolate the insulating medium between the high-voltage side and the low-voltage side, it has high safety and reliability and is usually used in power systems that require high reliability, such as power substations, industrial production lines, etc.
[0003] The existing internal cooling device of the dry-wet separation transformer also needs to use fan blades for air flow for cooling. When the dry-wet separation transformer is used for a long time, the dust screen of the vent will accumulate a lot of dust, which will eventually cause a lot of dust to adhere to the surface of the fan blades. Dust blocking the dust screen of the vent will reduce the air circulation, reduce the internal ventilation effect, cause the internal temperature of the dry-wet separation transformer to rise, and reduce the cooling efficiency, thereby affecting the normal operation and performance of the dry-wet separation transformer. Dust accumulation on the surface of the fan blade will increase aerodynamic resistance, make the fan blade run poorly, reduce its cooling effect, cause the internal temperature of the dry-wet separation transformer to rise, and increase the risk of failure. Long-term high temperature state will accelerate the aging of the internal insulation material of the dry-wet separation transformer, and reduce the life of the dry-wet separation transformer. At the same time, excessive temperature will also cause thermal expansion of electrical components, increase the wear of internal parts, and further affect the reliability and life of the dry-wet separation transformer.

[0012] Compared with the prior art, the utility model provides a dry-wet separation transformer cooling device, which has the following beneficial effects:
[0013] 1. The dry-wet separation transformer cooling device cooperates with each other through the fan blades, the fan frame, the first axis, the dustproof net and the double-axis motor. The first axis synchronously drives the fan blades to rotate at a high speed in the fan frame to dissipate heat and cool the high-voltage side of the transformer and the low-voltage side of the transformer inside the dry-wet separation transformer device. The high-speed rotation of the fan blades can quickly blow air into the dry-wet separation transformer device, accelerate the heat dissipation efficiency of the radiator outside the high-voltage side of the transformer and the low-voltage side of the transformer, and the radiator can transfer heat from the inside of the dry-wet separation transformer device to the external environment more quickly, effectively reducing the operating temperature of the dry-wet separation transformer device.

[0014] 2. The dry-wet separation transformer cooling device can clean the dust on the dustproof net through the cooperation of the cleaning plate, the cleaning cavity, the ball shaft, the bristles and the dustproof net, so as to maintain good ventilation and ensure smooth air flow. When the bristles come into contact with the dustproof net, the dust can be cleaned more thoroughly and completely removed from the dustproof net, which helps to prevent dust from accumulating on the dustproof net, clogging the dustproof net opening and adhering to the surface of the fan sheet, ensuring that the air can pass smoothly and ensuring that the fan sheet effectively cools the high-voltage side and the low-voltage side of the transformer, so that the air can easily enter from the dustproof net and the fan sheet can cool the high-voltage side and the low-voltage side of the transformer.
