Problems solved by technology

However, these devices all use direct water cooling instead of atomizing and spraying water, which will cause a lot of waste of water, which does not meet the current energy-saving requirements
And directly splashing the water mass on the transformer will easily cause a short circuit in the live part and cause an accident.

Description

technical field [0001] The invention relates to the technical field of transformer cooling protection, in particular to a hybrid cooling system for transformers on the ground in substations. Background technique [0002] The heat dissipation and cooling of power transformers during operation plays an important role in the safe operation of transformers. Common power transformers are mainly oil-immersed transformers, and the main heat dissipation components are radiators composed of multiple groups of fins connected by sheet-like heat sinks, which use air convection to naturally cool down and install fans at the bottom of the heat sinks. Cool down the heat sink by blowing air to speed up the air circulation, which can meet the operation requirements of the transformer under normal circumstances; In the case of load operation, the oil temperature in the transformer is high, and the original heat dissipation method cannot meet the requirements. In order to ensure the safe oper...
