Indoor dust-free ventilation inner and outer circulation device

Abstract

The invention belongs to the field of auxiliary electrical devices in a substation, and relates to refrigeration cooling equipment in the substation, in particular to an indoor dust-free ventilation inner and outer circulation device, which comprises an intelligent environmental safeguard box placed in the substation, and is characterized in that an air outlet is arranged on one side wall of the substation, and an indoor temperature sensor is arranged on the air outlet; an intelligent environmental safeguard system is arranged on the other side wall of the substation, and an outdoor temperature sensor is arranged on a fresh air inlet door of the intelligent environmental safeguard system; and the air outlet, the indoor temperature sensor and the outdoor temperature sensor are connected with the intelligent environmental safeguard box through leads. A fan is matched with an air conditioner to be used, so that the indoor temperature of the substation can be reduced more quickly under the assistance of the temperature sensors, and meanwhile, the purpose of saving power of the air conditioner is achieved, and the operating cost of the substation is effectively saved.

Description

technical field [0001] The invention belongs to the field of substation auxiliary electrical equipment, and relates to indoor refrigeration and cooling equipment of a substation, in particular to an indoor dust-free ventilation internal and external circulation device. Background technique [0002] At present, there are roughly two ways to cool down the interior of underground substations: one is to use exhaust fans to ventilate and cool down, and the other is to install air conditioners in the room to directly cool down. Brings up many problems. Ventilation and cooling by exhaust fans will bring a lot of dust, salt and acid substances floating in the air, which will adhere to the surface of electrical equipment to form dirt, affect the service life of electrical equipment, and cause potential safety hazards. The use of air-conditioning equipment for cooling, due to poor natural ventilation indoors in underground substations, poor ventilation conditions, poor air quality, h...

Problems solved by technology

[0002] At present, there are roughly two ways to cool down the interior of underground substations: one is to use exhaust fans to ventilate and cool down, and the other is to install air conditioners in the room to directly cool down. bring a lot of problems

Ventilation and cooling through exhaust fans will bring a lot of dust and salt and acid substances floating in the air, which will adhere to the surface of electrical equipment to form dirt, which will affect the service life of electrical equipment and cause potential safety hazards

However, air-conditioning equipment is used to cool down, because the natural ventilation in the underground substation is not smooth, the ventilation conditions are not good, the air quality is poor, the energy consumption is high, the air flow is uneven, and the purpose of uniform cooling of the substation cannot be achieved.
