Study on Optimization Scheme of Cooling Mode of Transformer Strong Oil Circulating Water Cooling System in Underground Substation

The core equipment of the main transformer substation in the power system. In Beijing, especially in the main urban area, most substations are built in the form of indoor underground stations due to the shortage of construction land. The heat dissipation problem of the main transformer has become the key to ensure the stable and reliable operation of the main transformer. Therefore, it is necessary to study the heat dissipation of transformer in underground substation.
