Automatic adjusting system for indoor temperature of transformer substation

Abstract

The invention relates to a transformer substation indoor temperature automatic adjusting system, which comprises a photovoltaic power generation assembly, a photovoltaic junction box, an inverter, a variable frequency water pump, a water cooling machine and a cooling device, and is characterized in that the photovoltaic power generation assembly is arranged at the top of a transformer substation, and the photovoltaic junction box is arranged at a position close to the photovoltaic power generation assembly; the inverter, the water cooling machine and the variable frequency water pump are arranged in a pump room, and the cooling devices are arranged in a transformer substation room and used for automatically adjusting the temperature in the transformer substation room. Through the method of circulating cold water cooling and air convection heat dissipation, the operation environment of indoor equipment is improved, then the effects of prolonging the operation life of the indoor equipment, increasing the load capacity of the equipment and reducing the load loss of the equipment are achieved, and meanwhile the problem that the local ventilation heat dissipation effect of the equipment is poor due to the fact that the position of an air inlet is limited is solved.

Description

technical field [0001] The invention belongs to the technical field of substations, in particular to an indoor temperature automatic adjustment system of a substation. Background technique [0002] Transformers, reactors and other power equipment in the substation room will release a lot of heat energy while converting electric energy. The released heat energy will cause the temperature of the surrounding environment to rise. The increase of the operating environment temperature of the equipment will directly affect the life of the equipment and reduce the Therefore, when the substation adopts the indoor layout plan, the main power equipment such as transformers and reactors need to consider effective ventilation and cooling measures. [0003] The ventilation of power equipment rooms such as transformers and reactors in substation households mainly adopts natural ventilation and mechanical exhaust by axial fans. The equipment room is ventilated and dissipated by installing ...

Problems solved by technology

At noon is the heat dissipation peak time of transformers and other equipment, and it is also the peak time of outdoor ambient temperature. The temperature difference between the air sucked in from the air inlet at the low position of the equipment room and the air discharged from the top becomes smaller, resulting in poor ventilation and heat dissipation. Even if the axial flow fan is used for mechanical exhaust, the effect is not significant

Due to the compact layout of indoo
