Abstract

The invention relates to a transformer and a transformer winding thereof. A cooling assembly is respectively provided with a shunt oil passage and a confluence oil passage at two sides of a coil, wherein one end of the shunt oil passage is provided with an oil inlet, and one end of the confluence oil passage far away from the oil inlet is provided with an oil outlet. A plurality of oil regions inthe coil are connected in parallel through the shunt oil ducts and the confluence oil ducts. Cooling oil enters the flow dividing oil channel from the oil inlet and enters the multiple oil areas fromthe flow dividing oil channel, and the cooling oil flowing through the oil areas is gathered in the flow gathering oil channel and finally flows out from the oil outlet. Due to the fact that the oil areas are connected in parallel, cooling oil entering each oil area cannot flow through the other oil areas. That is to say, the temperature of the cooling oil entering the oil areas is low, and the temperature of the cooling oil entering each oil area is approximately the same. Therefore, the effect of absorbing heat by the cooling oil is better, and the heat dissipation effect difference caused by the temperature difference of the cooling oil in different oil areas can be avoided. Therefore, the transformer and the transformer winding thereof are good in cooling effect.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment, in particular to a transformer and a transformer winding thereof. Background technique [0002] When the transformer is working, the coil will generate a lot of heat. The load loss of the transformer is related to the temperature, the higher the temperature, the greater the loss. Therefore, the transformer needs to effectively dissipate heat when it is working. At present, the windings in most transformers are cooled by oil immersion. That is, the cooling oil passes through multiple oil zones in sequence to take away heat, so as to achieve the purpose of cooling. However, the cooling effect of the existing cooling method is not good, and there are problems such as excessive local temperature rise. Contents of the invention [0003] Based on this, it is necessary to provide a transformer with a better cooling effect and a transformer winding thereof fo...
