1. High-quality insulation materials and processes
To prevent leakage of Intensive Bus Duct, we must first start from the source, that is, use high-quality insulation materials and exquisite insulation technology. The conductor of the bus duct should be tightly wrapped with high-quality insulation materials, such as high-purity polyvinyl chloride (PVC) or epoxy powder coating. These materials have good insulation properties and chemical stability, and can effectively prevent current leakage. During the production process, it is necessary to ensure that the thickness of the insulation layer is uniform and there are no defects such as bubbles and cracks. Because even tiny insulation defects may gradually expand under the action of the electric field during long-term operation, resulting in a decrease in insulation performance and causing leakage hazards. Through strict quality control, the initial insulation resistance of the bus duct is guaranteed to meet high standards, laying the foundation for safe operation.
2. Reasonable grounding system
A reasonable grounding system is a key link in preventing leakage hazards. Intensive Bus Duct should be equipped with a reliable grounding device, and the grounding resistance must meet relevant standards. The cross-sectional area of the grounding wire should be large enough to ensure that the current can be quickly introduced into the ground when leakage occurs. Generally speaking, the grounding conductor should be yellow-green double-color wire, which is easy to identify. At the same time, the metal shell of the bus duct must be well connected to the grounding system to form an equipotential body. In this way, even if leakage occurs inside, the potential of the shell can always remain close to the earth, thereby avoiding electric shock accidents when people touch the shell. In addition, it is necessary to regularly check whether the connection of the grounding system is firm and whether the grounding resistance has changed, and timely discover and repair potential problems.
3. Waterproof and moisture-proof measures
Water and moisture are important factors that cause leakage in the bus duct. Intensive Bus Duct should be installed in a dry environment. If a humid environment cannot be avoided, effective waterproof and moisture-proof measures must be taken. During installation, sealants or gaskets can be used at the connection of the bus duct to prevent moisture from entering. For areas that may be washed by rain or soaked in water, waterproof bus ducts or protective facilities such as awnings should be used. In addition, the humidity around the bus duct should be monitored regularly. When the humidity exceeds the specified range, dehumidification measures should be taken in time, such as installing a dehumidifier or ventilation equipment, to ensure that the operating environment of the bus duct is dry.
4. Regular inspection and maintenance
Regular inspection and maintenance are important means to ensure the safe operation of bus ducts and prevent leakage. The insulation resistance of the bus duct should be measured regularly using a professional insulation resistance tester, and archived data should be established to promptly discover the trend of insulation resistance changes. Once the insulation resistance drops, the cause should be quickly found, such as whether there are insulation aging, moisture, local overheating and other problems. At the same time, the appearance of the bus duct should be inspected to see if there is any damage, deformation or corrosion, especially at the connection and interface. For any problems found, repair or replace parts in a timely manner to eliminate the leakage risk in the bud.
