Abstract

The invention discloses an oil storage circulating cooling system of an oil-immersed transformer. The system comprises an oil tank, an oil pump, an oil storage tank, a water tank, a reservoir, a first heat dissipation pipe, a second heat dissipation pipe, a water inlet pipeline, a drain pipeline, a water spray pipeline, a water pump, a draught fan, a cooling frame, a temperature sensor and a controller, one end of the first heat dissipation pipe is connected with an oil outlet of the oil tank through the oil pump, the other end of the first heat dissipation pipe communicates with an oil inlet of the oil storage tank, one end of the second heat dissipation pipe is connected with the oil outlet of the oil storage tank, the other end of the second heat dissipation pipe communicates with the oil inlet of the oil tank, the oil storage tank is arranged in the water tank, a water inlet and a water spray opening are formed in one side face of the water tank, a water spray opening is formed in the other side face of the water tank, an outfall is formed in the bottom of the water tank, one end of the water inlet pipeline is connected with the water inlet, the other end of the water inlet pipeline communicates with the reservoir, one end of the drain pipeline communicates with the outfall through the water pump, and the other end of the drain pipeline communicates with the reservoir. The oil storage circulating cooling system disclosed by the invention has the advantages of simple structure, graded heat dissipation and improved heat dissipation effect of the cooling system.

Description

technical field [0001] The invention relates to the technical field of oil-immersed transformer cooling devices, in particular to an oil-immersed transformer oil storage circulation cooling system. Background technique [0002] During the operation of the transformer, a large amount of heat is generated due to internal losses, which causes the transformer to heat up and cause the temperature to rise. Under the action of long-term high temperature, the insulating material will accelerate aging and gradually lose its electric strength, thus affecting the normal operation of the transformer and shortening the service life of the transformer. Therefore, the long-term, reliable and efficient operation of the transformer cooling system is a necessary condition to ensure the normal operation of the transformer. At present, the existing transformer cooling systems include oil-immersed, oil-immersed air-cooled, forced oil-circulated air-cooled and forced oil-circulated water-cooled,...
