Attention to dust removal in apcups power maintenance

In the environment of apcups power supply, there will be some dust more or less. The staff usually maintain the UPS power supply and focus on the host and apcups battery. They may sometimes ignore the small dust. In fact, the dust accumulation has a great impact on the Schneider UPS host. This paper will make a simple statement on the dust removal problem of UPS power supply, which can bring new understanding to users.

In some areas with dry climate, because there is a lot of dust in the air, the wind in the ups host will bring the dust into the machine for precipitation. When the air is wet, it will cause the control disorder of the host and cause the host to work abnormally, and send out false alarms. A large amount of dust will also cause poor heat dissipation of Schneider UPS power supply, cause the temperature rise in the machine, and affect the service life of apcups power supply, More serious is that it will cause UPS host explosion. Therefore, we must pay attention to the dust removal of Schneider ups.

Generally, Schneider UPS equipment is overhauled every four years. First, all the fans of ups are replaced. Then, according to the operation condition, professional personnel check the ripple of DC circuit on line, 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 cleaning method is: after cleaning and maintenance, start to install the plug-in, pay attention to the plug-in should be inserted tightly, and the secondary plug should be inserted well. Check whether the fan and cover plate resonate after power on. If all the above conditions are normal, Schneider ups will continue to bypass the power supply load manually. In the case of no load, professional and technical personnel will supply power to UPS separately and commission the automatic bypass, rectifier and inverter. If the debugging 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 or not.

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