Under normal use, the maintenance workload of the high-frequency switch power supply equipment is minimal, mainly focusing on dust prevention and regular dust removal. Especially in areas with dry climates, there are a lot of ash particles in the air, and dust will deposit inside the machine. When encountering humid air, it can cause the control of the main engine to be disrupted, resulting in abnormal operation of the main engine and inaccurate alarms. A large amount of dust can also cause poor heat dissipation of the device. Generally, it should be thoroughly cleaned once every quarter. Secondly, during dust removal, check for any loose or loose connections and connectors
Due to the inability of the rectifier to eliminate instantaneous pulse interference, there are still interference pulses in the rectified voltage. In addition to the function of storing direct current energy, the equivalent capacitance of a battery is directly proportional to the capacity of the energy storage battery. Therefore, the maintenance and repair of batteries is very important. Although maintenance free batteries are used in battery packs, this only eliminates the previous work of measuring, proportioning, and regularly adding distilled water. However, since the impact of working conditions on the battery has not changed, and the impact of abnormal working conditions on the battery has not changed, the operation of the battery is entirely in a floating charge state, in which case it should be discharged at least once a year. Before discharging, the battery pack should be evenly charged to achieve the balance of the entire battery pack. If one of the batteries reaches the discharge termination voltage during the discharge process, the discharge should be stopped. To continue discharging, the lagging battery must be removed first before discharging. Confirmatory discharge is not about pursuing the percentage of discharged capacity, but about focusing on and discovering and dealing with outdated batteries, and conducting verification discharge experiments after processing the outdated batteries. This can prevent accidents and prevent backward batteries from deteriorating into reverse polarity batteries during discharge. Each group of batteries should have at least 8 labeled batteries as a reference for understanding the working conditions of the entire battery pack. The labeled batteries should be regularly measured and recorded. The items that need to be checked frequently in daily maintenance include: cleaning and testing the voltage and temperature at both ends of the battery; Check for looseness and corrosion at the connection, and check the pressure drop of the connection bar; Whether the appearance of the battery is intact, and whether there is any shell deformation or leakage; Is there any acid mist escaping around the pole and safety valve; Whether the host device is functioning properly, etc. Maintenance-free batteries should be operated and managed meticulously, meticulously, and in a standardized manner to ensure that the equipment maintains good operating conditions, thereby extending its service life; Ensure that the DC bus regularly maintains a qualified voltage and the discharge capacity of the battery; Ensure battery operation and personnel safety and reliability. This is the purpose of battery maintenance, as well as the content and operating rules included in the battery operation regulations. When a battery with reverse voltage, high voltage drop, large pressure difference, and acid mist leakage is found in the battery pack, corresponding methods should be used to restore and repair it in a timely manner. Batteries that cannot be restored and repaired should be replaced. But batteries with different capacities, performance, and manufacturers cannot be connected together, otherwise it may have adverse effects on the entire set of batteries. Expired battery packs should be replaced in a timely manner to avoid affecting the power system and device host

When there is a malfunction in the power system, the cause should be identified first, distinguishing between the load, the power system, and the host or battery pack. Although the host of the switch power supply system has a fault self check function, it is opposite to the point and convenient for replacing parts. However, to repair the fault point, a lot of analysis and testing work still needs to be done. In addition, if there is a malfunction in the self check section, the displayed fault content may be incorrect

For faults such as breakdown, fuse breakage, or burning of components in the host, it is necessary to identify the cause and eliminate the fault before restarting, otherwise the same fault will occur consecutively. Even the best equipment has a lifespan and may experience various malfunctions. However, doing well in maintenance can prolong its lifespan and reduce the occurrence of malfunctions. Don't neglect the maintenance work that should be done just because it is highly intelligent and maintenance free. Prevention is an important guarantee for safe operation at all times
