During the operation of the bus duct power supply system, some problems are inevitable. Here are some solutions from Guangdong Cisco General Electric Busway Manufacturer:
Continuously inspect the surrounding environment of the entire management system for leaks, water sprays, potential sources of moisture, heavy objects that may pose a threat to the system, and heat sources that may affect the temperature rise of the information system, and check for any foreign objects entering the interior. Check whether the system components are damaged or corroded, and whether the elasticity of the bracket spring is appropriate. If any problems are found, they should be replaced immediately.
Regularly clean the surface dust of the busbar trunking system to ensure good heat dissipation. After the system undergoes maintenance, check the insulation resistance and keep a record of the maintenance work before re powering on.
During long-term operation, the joint temperature rise should be checked regularly once a year, and the joint temperature rise should be qualified according to GB7251 standard, not exceeding 70 ℃ (40 ° C for different environmental temperatures). Check whether the connecting bolts and conductor contact parts of each joint are loose.
Prevent the joint from overheating due to increased working resistance caused by looseness. Check the insulation materials and whether there is aging, and whether the conductive parts have melted or deformed. If there is a phase failure or insulation breakdown, it should be dismantled in sections and checked with a voltage tester to identify system faults, or replaced or redesigned for analysis of insulation coating technology treatment. Check if the pins of the bus duct system plug-in box are in good contact with the bus
