Maintenance of intelligent monitoring module and high-frequency switching power supply module

The intelligent monitoring module and high-frequency switching power module require minimal maintenance work for the host under normal use, mainly for dust and lightning protection. Especially in areas with dry climate, there are more dust particles in the air, and axial fans will cause dust to deposit inside the machine. When the air is humid, it can cause insulation failure inside the machine, leading to abnormal operation of the host. In addition, a large amount of dust can also cause poor device performance. Lightning protection in summer is particularly important. The module should be thoroughly cleaned every quarter, and all connectors and plugs should be checked for looseness and poor contact. Regularly verify whether there are any changes in the parameters of the intelligent monitoring module and high-frequency switching power supply system to prevent human or unintentional changes to the set parameters.

Before the arrival of the thunderstorm season, the lightning protection system of the substation and the lightning protection device of the DC power supply should also be checked. Every six months, the operation mode of the intelligent high-frequency switching power supply system should be tested and inspected to prevent damage to the battery caused by the inability to switch between uniform and floating charging states in a timely manner. Check whether the host equipment is normal and ensure that the DC bus maintains a qualified voltage and battery discharge capacity regularly; For faults such as breakdown, fuse failure, or device burnout in the host, the cause must be identified and the fault must be eliminated before restarting, otherwise it will cause more serious faults.
