Thermostat device for substation

Abstract

Provided is a thermostat device for a substation. Heat generated during the running of a transformer inside a transformer chamber is emitted indoors, and the temperature of indoor air rises; high-temperature gas enters a heat exchange mechanism; low-temperature water serves as a refrigerant for the heat exchange mechanism, the released heat is partially absorbed by the low-temperature water, and the high-temperature gas becomes low-temperature gas; the low-temperature gas is discharged out of the heat exchange mechanism and is in contact with the surface of the transformer, and forced convection heat exchange is performed on the surface of the transformer; the low-temperature gas absorbs the heat emitted by the transformer again to become the high-temperature gas, the high-temperature gas enters the heat exchange mechanism to perform cooling, and the circulation is performed; the low-temperature water of the heat exchange mechanism becomes high-temperature water after absorbing the heat, the high-temperature water is pressurized through a water pump to enter a water cooling mechanism through a pipe, the high-temperature water releases heat through the effect of the water cooling mechanism to become the low-temperature water, the low-temperature water flows into the heat exchange mechanism through a pipe to become the refrigerant again, and the circulation is performed. The whole process is not subject to the influence of the wind direction and the external environmental temperature, efficiency and comprehensiveness in heat dissipation inside the transformer chamber can be achieved, and the effect of maintaining the temperature inside the transformer chamber constant is achieved.

Description

technical field [0001] The invention belongs to the technical field of power equipment, in particular to a substation constant temperature device. Background technique [0002] With the development of the national economy, substations have entered the city center to solve the growing demand for urban basic life and production electricity, and substations basically adopt indoor layout. [0003] At present, the commonly used indoor layout is to place high-voltage, large-capacity power transformers indoors. In order to ensure that the indoor layout achieves the same rated output power and operating environment as the outdoor layout, it is necessary to ensure that the heat dissipation and ventilation of the indoor layout transformers are good. ; And it is necessary to consider the noise shielding requirements for substations located in the city center. The ventilation and noise reduction scheme of the main transformer room of the existing substation mainly adopts the ventilatio...
