The maintenance method of the distribution cabinet is the key link to ensure its stable operation and extend its service life. The following is a detailed summary of the maintenance method of the distribution cabinet:

1. Regular inspection
   Regular inspection is the basic work of distribution cabinet maintenance. It is necessary to regularly check whether the appearance, internal electrical components, wiring, etc. of the distribution cabinet are normal to ensure that the equipment is running normally. At the same time, it is also necessary to check whether the safety facilities such as the grounding device and interlocking device of the distribution cabinet are intact. It is recommended to formulate a regular inspection plan, such as a routine inspection once a month, and keep relevant records.
2. Cleaning and maintenance
   The cleaning and maintenance of the distribution cabinet is also very important. Regularly clean the dust and debris inside the distribution cabinet, especially the dust cleaning of components such as contactors and relays, which is more meticulous, which helps to improve the heat dissipation performance and operation stability of the equipment. At the same time, the surface of the distribution cabinet needs to be cleaned to avoid affecting the heat dissipation and safety performance of the equipment due to dust accumulation. It is recommended to perform thorough cleaning and maintenance once a quarter.
3. Repair and replacement
   For faulty or damaged electrical components in the distribution cabinet, they need to be repaired or replaced in time. During the maintenance process, it is necessary to follow the relevant safety operating procedures to ensure the quality and safety of the maintenance. For electrical components that often fail, in-depth analysis and investigation are required to find out the causes and take corresponding measures to improve them.
4. Tightening inspection
   The electrical components and wiring in the distribution cabinet need to be tightened regularly. Use tools such as torque wrenches to check the tightness of components such as screws and nuts. For loose or detached components, tighten them in time to prevent safety accidents caused by looseness. At the same time, it is also necessary to check whether the connection parts such as cables and wires are loose or have poor contact, and take timely measures to repair or replace them.
5. Functional test
   In order to ensure the normal operation of the distribution cabinet, its function needs to be tested regularly. You can simulate the operation of electrical components such as switches, contactors, relays, etc. of the distribution cabinet to check whether their operation is normal. At the same time, it is also necessary to test whether safety facilities such as interlocking devices and protective devices are effective. It is recommended to conduct a comprehensive functional test once a year.
6. Preventive maintenance
   Preventive maintenance is one of the important links in the maintenance of distribution cabinets. By regularly performing preventive maintenance on the distribution cabinet, problems and hidden dangers of the equipment can be discovered in time, and corresponding measures can be taken for repair and replacement. This includes checking whether the busbar and its lower leads are firm, whether the secondary circuit wiring is firm, whether the fuse is intact, and measuring the insulation resistance. It is recommended to perform comprehensive preventive maintenance once a year to ensure the safety performance of the equipment.

VII. Safety protection
As a high-voltage, high-current and other equipment, the safety protection of the distribution cabinet is very important. It is necessary to set up safety facilities such as fences and warning signs around the distribution cabinet to prevent unauthorized personnel from contacting the distribution cabinet. At the same time, operators need to undergo professional training and education, master relevant safety knowledge and operating procedures, and ensure the safe operation of the equipment.

VIII. Operation records
In order to better understand the operating status and maintenance history of the distribution cabinet, operation records are required. The operation record should include information such as the operating status of the equipment, fault phenomena, and maintenance content. It is recommended to set up a dedicated person to record the operation of the distribution cabinet and report abnormal conditions in a timely manner.

In summary, the maintenance methods of distribution cabinets include regular inspection, cleaning and maintenance, repair and replacement, fastening inspection, functional testing, preventive maintenance, safety protection and operation records, etc. The effective implementation of these maintenance methods can ensure the normal operation of the distribution cabinet and extend its service life, providing a strong guarantee for the stable operation of the power system.
