Abstract

The present invention belongs to the field of transformers, especially an oil-immersed three-phase transformer. For the existing cooling fins, the cooling fins are usually installed inside to dissipate heat through ventilation holes, but such The heat dissipation efficiency is not high, and the ventilation holes are all open, which will easily lead to dust entering the transformer and causing damage to the transformer. The following solution is proposed, which includes a transformer casing with a hollow structure, and an oil tank is fixedly installed on the top of the transformer casing , The oil inlet pipe and the oil outlet pipe are fixedly installed in the transformer shell. The present invention is simple in structure, easy to operate, can effectively dissipate the heat generated by the main body of the transformer during the working process, and can effectively dissipate heat when the external temperature is relatively high, so as to ensure the normal operation of the main body of the transformer. At the same time, when the heat dissipation is completed, it can The heat dissipation port is sealed to prevent dust from entering, so people's needs are met.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an oil-immersed three-phase transformer. Background technique [0002] The three-phase transformer is a complete set of voltage transformation equipment, which can be used for terminal power supply and ring network power supply. The conversion is very convenient and ensures the reliability and flexibility of power supply. However, the transformer will generate a lot of heat during operation. Mainly by setting air passages or oil passages in the body, the heat is taken away by the circulating flow of gas or oil to dissipate heat. Its structure is complex, manufacturing and maintenance is difficult, and it is highly specific to the type of transformer and does not have universal applicability; [0003] Traditionally, heat sinks are also used to dissipate heat, but the heat sinks are usually installed inside to dissipate the heat through the ventilation holes, but the heat diss...
