Due to the continuous improvement and advancement of social level, distribution boxes are widely used in daily life. Rust and mold on distribution boxes are often caused by moisture. When moisture is found, methods should be immediately used for moisture-proof treatment. However, during the treatment process, many people have found that even using these methods cannot completely prevent moisture from coming, especially on rainy days and when there is a large temperature difference, the moisture situation is particularly severe. Generally speaking, the humidity and accumulated water in the operating environment of electrical equipment in distribution boxes are the main factors affecting the safe operation and power utilization of electrical equipment.
The personnel responsible for setting the price of distribution boxes should consider multiple aspects when dealing with moisture-proof and dehumidification of electrical equipment, namely the relative sealing treatment of the equipment; Prevention of the origin of humid air; Dehumidification treatment of accumulated moist air inside the cabinet. Use power outage opportunities to clean equipment and ensure cleanliness inside the distribution cabinet. Closed distribution cabinet. The ventilation windows and vents of the high-pressure chamber shall be filtered according to the regulations and rules. Keep the high-pressure indoor air clean.
Waterproof sealing shall be applied to the cable trenches, cable tunnels, and cable holes below the distribution box, and natural ventilation and moisture drainage channels shall be installed to ensure that the air in the cable tunnels is dry. The bottom iron plate of the indoor enclosed busbar bridge for outgoing lines should be changed to a steel wire mesh plate, or a 100mm gap should be opened horizontally. When rainwater enters through the fixed steel plate of the wall sleeve of the outgoing line, it can be discharged from the gap and cannot enter the distribution box.
