What are the disadvantages of dual -machine redundant improvement of the reliability of the UPS power system?
1. Unable to switch and cause output interruption
When the UPS power supply board or the power module fails, the UPS power supply immediately stops the work and the output is interrupted. At this time, UPS can no longer be shifted from static switch to bypass. This situation occurs on the main UPS power machine. At this time, the UPS power supply is good or uniform, and the power supply of the entire computer system will be interrupted. When there is a problem with the UPS power control circuit, the inverter is burned instantaneously and some other reasons, and the static switch may not be opened and causes interruption.(Lithium - Ion Battery Equipment)
2. Switch instantaneous output is interrupted
In order to ensure the continuous output waveforms, UPS uses a preconceived and then disconnecting technology, that is, there is a stack of superpower output and inverter output through the static switch to ensure that the output is not intermittent. Consistent, otherwise, it may cause the output during the switching process.
3. In the power supply system, two new public fault points have been added
Once the main UPS static switch fails, the switching at this time will cause load power supply interruption. When the overload occurs, the main/from UPS will turn the road in order. At this time, the static switch of the UPS will also cause the output interruption if there is a problem.
4. Low equipment for equipment use
Throughout the power supply process, there is always a UPS for a long time without use, the use efficiency is low, and the battery that backups UPS has been in a floating charging state for a long time, the battery cannot discharge, and the battery life is greatly shortened.
5. Difficulty in maintenance
When the host fails and the power supply is switched to the power supply, the user's load cannot be stopped and the UPS power supply cannot be turned off for maintenance. Once the machine fails, the entire power supply system will be interrupted.
The advantages of UPS power redundant and machine
In the parallel redundant UPS system, when working normally, all stand -alone UPS run parallel, and the average load is loaded. If a stand -alone UPS failure, or if it is out of the system for maintenance, the remaining stand -alone UPS has sufficient capacity supply load to ensure that the load supply is uninterrupted, so the load is not necessary to convert the load to bypass power.
The performance of the dual -machine redundant UPS power system is stable and the economic benefits are obvious. In this 1+1 system, the two UPSs are redundant. When one is broken, the other can bear all the loads.
