One kind of offshore wind power main transformer cooling system

The present invention discloses an offshore wind power main transformer cooling system, including the main transformer tank accident, accident tubing and cooling water tank. Main transformer cooling system is provided for collecting accident and oil discharge oil collection pits. Accidents tank floating on the sea, and is located below the main transformer. Oil into the oil terminal end of the oil collecting pit accident tubing set accordingly, an oil terminal and pipeline accidents inlet end accident tank set accordingly accident tubing for the oil collection pit row guide the oil accident accident tank. Cooling water tank and the fuel tank is connected to the accident, and the cooling water tank located beneath the fuel tank accident, cooling water tank has a return pipe, outlet pipe and is provided on the outlet pipe or return pipe of the pump. Return pipe communicating to the outlet end of the cooling system, communication with the outlet pipe to the inlet side of the cooling system. The present invention can save space on the offshore booster station platforms, to replace air-cooled main transformer to reduce the temperature of the way, and the cooling effect and energy saving.
