The maintenance of distribution cabinets mainly includes the following aspects:
Regular inspection: Regularly check whether the appearance of the distribution cabinet is intact, whether the wiring is loose or corroded, and perform necessary tightening and cleaning. At the same time, check whether the warning signs and maintenance signs are placed correctly.
Cleaning and maintenance: Regularly clean the exterior and interior of the distribution cabinet, use a cleaning cloth or hair dryer to remove dust and dirt, and be careful not to use corrosive cleaning agents.
Insulation testing: Regularly conduct insulation tests to ensure that the insulation performance of the distribution cabinet meets the regulatory requirements. Use insulation testing instruments to measure insulation resistance. If insulation resistance is found to be too low, it should be dealt with promptly.
Electrical component inspection: Regularly inspect the electrical components of the distribution cabinet, such as circuit breakers, relays, contactors, etc., to ensure that they are working properly. If any malfunction or damage is found, it should be repaired or replaced in a timely manner.
Grounding inspection: Regularly check the grounding status of the distribution cabinet to ensure that the grounding wires are well connected and not damaged or corroded. If any problems are found, they should be repaired or replaced in a timely manner.
Overload protection: Regularly check whether the overload protection device of the distribution cabinet is working properly, and distribute the load reasonably according to the load situation to avoid the occurrence of overload phenomenon.
Temperature control: Regularly check the temperature control system of the distribution cabinet to ensure that the temperature is within a safe range. If the temperature is found to be too high, the air duct and radiator should be cleaned in a timely manner, and the cooling fan should be checked for normal operation.
Safety signs: Install signs for distribution cabinets, including voltage level, current capacity, and other information, to ensure that operators can correctly identify and operate them.
Record maintenance: Regularly record the maintenance status of the distribution cabinet and archive it for subsequent maintenance and management.
