[0002] Coal mine is an important energy production base, and the reliability and stability of its power system are directly related to the safe operation and production efficiency of the mine. As an important device in the coal mine power system, the transformer is responsible for converting high-voltage current into low-voltage current for use by coal mine equipment. However, in the coal mine production environment, the load of the transformer is often large, generating a lot of heat. In order to ensure the continuous and stable operation of the transformer, cooling measures are usually taken. The traditional transformer cooling methods include natural cooling and forced oil circulation cooling. However, in the relatively closed space of the coal mine, the heat dissipation effect may be low. Therefore, a coal mine transformer external cooling equipment is proposed.

[0003] In special environments such as coal mines, transformers often need to be in a high-load state for a long time, resulting in serious heating of the transformer body. The cooling system inside the transformer may not be able to effectively provide sufficient heat dissipation capacity when the load increases, which may affect the stability of the transformer during operation. At the same time, the existing part of the external cooling equipment is relatively troublesome when connecting and fixing it with the transformer. Therefore, technical improvement is urgently needed. UTILITY MODEL CONTENT
