Abstract

The invention relates to a waste heat recycling device of a transformer substation. The waste heat recycling device comprises a housing, a water heater, a re-cooler, an air feeder, an expansion valve,a compressor and an evaporator, wherein the top of the housing is connected with a guide air tube; a horizontal sealing partition is arranged in the housing; the water heater is arranged below the sealing partition; the water heater is connected with a water inlet and a water outlet tube; an air inlet is formed in the periphery of the housing; the re-cooler is arranged above the air inlet; the air feeder is arranged above the re-cooler; one side of the air feeder is equipped with the expansion valve, and the other side of the air feeder is equipped with the compressor; the evaporator is arranged above the air feeder; the water heater is connected with the compressor through a refrigerant pipe; the cooler is connected with the water heater through a refrigerant pipe; the expansion valve isconnected with the re-cooler through a refrigerant pipe; the evaporator is connected with the expansion valve through a refrigerant pipe; and the compressor is connected with the evaporator through arefrigerant pipe. The waste heat recycling device of the transformer substation is utilized for effectively recycling radiated equipment heat in the transformer substation, so that the environment temperature of the transformer substation is controlled within a reasonable range; and recycled waste heat directly heats cold water, so that the heated cold water is supplied to a corresponding servicearea to use.

Description

technical field [0001] The invention belongs to the field of electromechanical engineering, and in particular relates to a waste heat recovery device of a substation, which is used for heating cold water and improving the indoor working environment of the substation by recovering the waste heat in the substation. Background technique [0002] Energy and environmental issues are one of the major social issues facing countries all over the world. With the development of the world economy, energy shortage and environmental pollution have become major problems restricting economic development. Energy conservation, emission reduction, and improvement of energy utilization efficiency have become global hot issues. How to recycle a large amount of waste heat produced in the production process has also attracted more and more attention. [0003] Due to the existence of resistance and reluctance in the transformer in the substation, a large amount of loss is generated in the iron c...
