Power transformer tank waste heat utilization device

Abstract

The invention discloses a power transformer tank waste heat utilization device which comprises a quadrilateral transformer tank. A hollow structure is arranged in the middle of the transformer tank, peripheral side walls of the transformer tank have a certain thickness, connecting pipe holes are formed in the peripheral side walls of the transformer tank, connecting pipes are arranged inside the connecting pipe holes, flow guide channels are formed inside the transformer tank by the connecting pipes, water inlet ends of the connecting pipes are connected with water inlet pipes, water outlet ends of the connecting pipes are connected with water outlet pipes, heat insulation layers are arranged on the peripheries of the water inlet pipes and the water outlet pipes, the connecting pipe holes are of U-shaped structures, a plurality of U-shaped structure connecting pipe holes are uniformly formed in the side walls of the transformer tank, and every two U-shaped structure connecting pipe holes are connected together through one connecting pipe. Unused waste heat can be reused, energy is saved, and environments are protected.

Description

Technical field: [0001] The invention relates to a waste heat utilization device, in particular to a power transformer box waste heat utilization device. Background technique: [0002] Power transformers inevitably generate a certain amount of heat during normal operation. Once the temperature of the transformer is too high, the coil insulation will age and be prone to failure. According to the regulations on the operation of power transformers, the normal operating oil temperature of the transformer should be lower than 85 degrees, the It must not exceed 95 degrees. If it exceeds the above value, the temperature of the inner coil of the transformer will exceed the temperature of the coil insulation, causing the transformer insulation to age and prone to failure. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a power transformer box waste heat utilization device capable of...
