In recent years, due to land and environmental constraints, low-voltage substations are often designed as compact layouts or even underground power stations. The environment of the substation often has disadvantages such as high temperature, high humidity, poor ventilation, dust accumulation, and toxic gas accumulation, which is not conducive to the long-term operation of electrical equipment, and even brings potential safety hazards, and also brings challenges to the reliable operation of the power grid.
    The intelligent control device of the operating environment is an environmental optimization system that integrates environmental perception, automatic control, aerodynamics and thermodynamic theory. The system has the characteristics of safety, cleanliness, energy saving and high efficiency, and is suitable for small substation, substation (distribution) station, switch station, especially indoor station or underground station with compact layout. The system is equipped with corresponding sensors, through the collection of temperature, humidity, air quality and other parameters of the operating environment, the system drives high-efficiency cooling and dehumidification equipment, high-speed centrifugal fans and other optional devices according to the intelligent control strategy set by environmental objectives, and regulates the temperature and humidity, cleanliness and flow rate of the gas in the environment. Optimization of local microclimate in the power station space. This system is of great significance to greatly reduce the failure and probability of power transformation (distribution) equipment, and greatly reduce the probability of creepage and arc flash.
