Pay attention to dust removal during maintenance of Schneider UPS power supply

In the environment where apcups power supply is used, there will be some dust more or less. The staff usually maintain Schneider UPS power supply, focusing on the host and Schneider UPS battery. These small dust may sometimes be ignored. In fact, there is too much dust, which also has a great impact on Schneider UPS host. A brief statement will be made on the dust removal of Schneider UPS power supply, which can bring new understanding to users.

In some dry areas, due to the large amount of dust in the air, the wind in Schneider UPS host will bring the dust into the machine for precipitation. When the air is wet, it will cause the host control disorder and cause the host to work abnormally, and send a false alarm. A large amount of dust will also cause the poor heat dissipation of Schneider UPS power supply, resulting in the increase of temperature in the machine, The service life of Schneider UPS power supply will be affected, and the more serious is that it will cause the explosion of Schneider UPS host. Therefore, we must pay attention to UPS dust removal.

Generally, Schneider UPS power supply equipment is overhauled every four years. First, replace all fans of Schneider UPS power supply. Then, according to the operation conditions, professionals will live check the ripple of DC circuit, check whether the DC capacitance and AC capacitance are abnormal from the appearance, and test the capacitance with a special meter to determine whether to replace the capacitance. The removal method is to reinstall the plug-in after cleaning and maintenance. Pay attention to plug the plug-in tightly and plug the secondary plug well. Check whether the fan and cover plate resonate after power on. If the above conditions are normal, apcups power supply will continue to bypass the power supply load manually. Under the condition of no load, professional technicians will separately supply power to Schneider UPS power supply and debug the automatic bypass, rectifier and inverter. If the commissioning is normal, Schneider UPS starts to switch from manual bypass to automatic bypass and then to inverter power supply. Secondly, during dust removal, check whether the connectors and plug-ins are loose and loose.

In addition to these dust removal tips, when we use Schneider UPS power supply, we should also develop a cleaning habit when we see dust on the ups host, so that the dust will not accumulate more and more. The ups host that remains clean for a long time will provide us with a better, more stable and reliable power supply.
