1. The high-pressure room of the substation is equipped with doors, windows, and ventilation fans, and some locations are not tightly sealed, which has an impact on moisture-proof and moisture-proof.

2. Although the indoor air conditioner has been installed, the dehumidification effect is not obvious. In the rainy season or when the external environment humidity is high, the wall ventilation grille and the gaps between doors and windows make the high-pressure indoor air directly communicate with the outside air, and the outdoor high-humidity air directly penetrates into the high-pressure room, and the indoor humidity increases. And part of the humid air is easy to enter the switch cabinet along the gap of the cabinet.
3. When the humidity in the cabinet is high and the temperature difference is large, the unsaturated water vapor of the ambient air in the cabinet will be instantly saturated, forming condensation on the components in the cabinet.
4. The switch cabinet is connected with the busbar bridge. Most of the cabinets are equipped with heating and damp-driving devices. The humid air in the cabinet will continue to evaporate after heating and enter the busbar bridge above the switchgear. There is no heating or damp-driving device in the busbar bridge. Although the bus barrel is provided with different forms of ventilation holes, most of them are located on both sides of the bus barrel and are relatively small. The air pressure inside and outside the bus barrel is the same. The principle of natural ventilation to achieve ventilation and damp driving is basically not achieved. Achieve good ventilation and damp dispelling effect.
5. The high-pressure room is relatively tightly sealed. When the ambient humidity is high and the temperature difference is large, the moist air will easily enter the room through the gaps in doors and windows, cable trenches and ventilation grids, and part of the moist air will enter the switch cabinet along the gaps in the cabinet. , It is easy to gather in the corners and cannot be discharged, which is easy to cause safety operation accidents. Because of its accidents are likely to occur in the rainy season, and the weather temperature is high.
Conclusion: Based on the analysis of site conditions and our company's technology and experience in moisture-proofing and dehumidifying power equipment for many years, it is recommended to dehumidify power equipment as a whole, not only to improve the humidity problem inside the power equipment, but also to improve the humidity problem in the environment of the power equipment.
