Transformer cooling device and method

Abstract

The invention provides a transformer cooling device, the transformer cooling device is arranged on a transformer cooling fin, the transformer cooling device comprises a temperature acquisition module, a temperature control module and a cooling processing module, the temperature acquisition module is arranged at the upper part of the transformer cooling fin, the temperature acquisition module is also connected with the temperature control module. And the cooling processing module is connected with the temperature control module. The invention further provides a transformer cooling method, a temperature reference value is set, the temperature data of the transformer are collected, then the temperature data and the temperature reference value are compared through the temperature control module, whether the valve is opened or not is determined, and if the valve is opened, cooling water flows to the cooling fin of the transformer for cooling. According to the transformer cooling device and method, a water cooling method is adopted, the influence of environmental factors on the heat dissipation efficiency is eliminated, the heat dissipation efficiency is effectively improved, the model type of the transformer is not required, and the transformer does not need to be changed.

Description

technical field [0001] The invention relates to the technical field of transformer cooling, in particular to a transformer cooling device and method. Background technique [0002] The transformer is one of the main equipment of the substation, which is used to transform the high voltage into various levels of voltage required by the user. The current 110kV substation is basically based on oil-immersed self-cooling transformers, but when summer comes, due to the superposition of various loads on the transformer, the oil temperature on the upper layer of the main transformer will be very high. At 45-50°C, the main transformer oil temperature will be higher. Oil-immersed self-cooling transformers dissipate heat through natural oil circulation and air cooling. The working principle of this heat dissipation method is: when the heat generated by the transformer winding heats up, it is transferred to the cooling oil in the transformer box, and the cooling oil will automatically ci...

Problems solved by technology

[0003] This cooling method, which only relies on the convection circulation between the heat sink of the transformer itself and the air with a lower temperature in the environment, has many disadvantages: first, the heat dissipation efficiency is low, especially in summer when the ambient temperature is high, and the heat convection effect is very poor; secondly, 220kV The above transformer radiators can be cooled by fans, but for 110kV transformers, due to the structure and design cost of the main transformer body, it is impossible to air-cool the 110kV transformers
