When to use UPS?
Thread Content
For control rooms such as tank farms and oil pump rooms, only instrument panels are installed. Is it generally required to use UPS for power supply? This post was last edited by naska on 2008-3-7 15:27 ]
We generally use UPS to power DCS, ESD, fire protection system control panels and IT servers. For example, the control of raw material tank farms does not use UPS.
Under normal circumstances, UPS power supply is not used, except for special requirements, such as if safety or workmanship is affected after a power outage, you should consider it.
The main function of UPS: 1. When it comes to production safety, we are worried about damage to processes and equipment caused by power outages. ； 2. Install UPS for short-term power supply to save operating parameters in case of unexpected power outage. ； 3. Resist power grid interference. The poster can combine the above points to see if it is necessary to add a UPS to your control room.
UPS is an uninterruptible power supply device. The general design power supply time is 30 minutes, which mainly depends on the system equipment and process safety requirements. :)
It is generally safer to use UPS
Important instruments that affect production generally need to provide power for about 30 minutes.
The functions of UPS The main functions of UPS are as follows: (l) When the mains power is interrupted, it can use its own battery to convert DC power into 220V AC power through the inverter circuit to supply power to computers and network systems, ensuring that computers and network systems can operate normally. (2) It has a voltage stabilizing effect on the mains power and can stabilize the voltage when the grid voltage fluctuates. (3) It can suppress power harmonic interference, instantaneous voltage drops, high-voltage surges, voltage waveform distortion, electromagnetic interference and other power pollution in the power grid, provide stable voltage and pure waveform power supply for computers and other equipment, and ensure the normal operation and data of computers and network systems without interference. (4) Avoid lightning strikes. Automatically save. The CPU-controlled UPS can allow the computer to automatically save and shut down before its battery is used up. The above are the basic functions of UPS. Other large UPS have many functions.
If the system requirements are not high, UPS power supply is not needed.
It depends on the safety level of the place. If after analysis, it is believed that if the power is cut off, it will cause death, huge economic losses, and serious environmental pollution, then the instruments there need to be powered by UPS.
