How UPS power supplies work and troubleshooting drum faults???
An UPS is essentially just a backup battery, designed to prevent the DCS from losing power in cases of unstable power supply or outages from external sources. An UPS failure does not affect the supply of voltage to the instruments; it can be repaired after the UPS is disconnected. However, emergency preparations for a power outage of the instruments should be in place during this period. Additionally, I’d like to give you a suggestion: try to minimize spelling errors. It should be “malfunction” rather than “guzhang”. People in technical fields should develop a more responsible work habit, that is, to be accountable for what they say and write.
A UPS is a set of batteries. It’s just the principle of an online battery; there’s nothing special about it. It should be noted that regular inspections and replacements are necessary.
In fact, by the time you notice a fault, it is already under inspection and repair. If you are still concerned about a power outage for the instruments during this period, it is advisable to have another set as a backup.
