Does the underground box-type substation have good waterproof and dustproof functions?

Underground box substations are usually installed in underground environments, so their waterproof and dustproof functions are particularly important. With the rapid development of urban power grids and the widespread application of underground substations, how to ensure the safe and stable operation of equipment in underground environments, waterproof and dustproof design has become a key factor that cannot be ignored.
The waterproof design of underground box substations is to deal with problems such as underground moisture, water accumulation and water penetration. During the design, the shell material of the substation is usually made of steel plates, aluminum alloys and other materials with strong waterproof properties, and is treated with anti-corrosion to enhance its water resistance. The sealing performance of the substation is also very important. All joints, doors and windows, wiring holes and other places are usually specially sealed to ensure that moisture cannot penetrate into the equipment. Especially in areas with high groundwater levels or more rain, waterproof design is particularly important, which can effectively prevent substation equipment from being damp, short-circuited or damaged, and ensure the stability of power supply.
In addition to waterproof design, dustproof function is also crucial. The environment of underground box substations is usually relatively closed, and dust, sand, and debris are easily accumulated around them. Long-term accumulation of dust may affect the normal operation of the equipment and even cause equipment failure. Therefore, the outside of the substation is usually designed with dustproof grids or filtering devices, which can effectively prevent dust, sand, etc. from entering the equipment. In the design of sealed doors and windows, efficient dustproof materials and technologies are also used to ensure that external dust cannot penetrate.
The air circulation design inside the substation is also very important. While ensuring waterproof and dustproof, it is also necessary to maintain proper ventilation inside the equipment. In order to prevent the accumulation of humid air and dust, the substation is usually equipped with a ventilation system, which will effectively filter dust and moisture in the external air through air filtration devices to maintain the dryness and cleanliness of the internal environment.
In practical applications, in order to ensure that the underground box-type substation can operate stably for a long time, regular inspection and maintenance are also important links that cannot be ignored. Although the waterproof and dustproof design can effectively reduce the impact of the external environment on the equipment, the sealing of the equipment may decrease over time, so it is necessary to regularly check whether the external waterproof and dustproof devices are intact. If problems such as aging of the sealing strip and loose joints are found, they should be repaired and replaced in time to avoid the intrusion of moisture and dust.
