Regarding the power supply for the control system

1. It can be used; the power cabinet is used to supply power to the instruments and valves； 2. The power for the control panel is also supplied by the power cabinet; it can be provided in part by a UPS and in part by mains electricity ； 3. Generally, the UPS room is under electrical management; the reason for requiring a separate setup is not clear

1. Fire prevention and heat dissipation: High heat generation: UPS units and batteries generate a significant amount of heat during operation; a separate room can be equipped with specialized air conditioning or forced ventilation systems to prevent equipment failures or fires caused by high temperatures. Battery risks: Lead-acid batteries may release hydrogen gas (especially in the event of a failure); a hydrogen detector and explosion-proof ventilation systems can be installed in a separate room to prevent the risk of explosion. Isolate the source of fire: A failure in UPS equipment can lead to electrical fires, and a separate room can effectively prevent the spread of fire and protect critical equipment such as servers. 2. Electrical safety: High-voltage isolation – The input/output terminals of a UPS are typically connected to high-voltage, high-current circuits; by using a separate room for these connections, proper wiring can be implemented to prevent accidental contact and reduce the risk of electric shock. Electromagnetic interference: The operation of a UPS can generate electromagnetic interference, and a separate room can shield against the impact on sensitive IT equipment such as servers and network devices. II. Operational and maintenance requirements 1. Environmental control: Stable temperature and humidity – Batteries are sensitive to temperature (optimal temperature: 20–25°C); a separate room can help maintain constant temperature and humidity, thereby extending the battery’s lifespan. Dust and moisture protection: Reduces the corrosion of circuits and batteries caused by dust and humidity, thereby improving reliability. 2. Operational convenience: Dedicated space allows for the centralized placement of equipment, neat wiring, and facilitates regular inspections, testing, or battery replacement. Noise reduction: UPS fans are quite noisy; a separate room can help reduce noise interference for staff and in the office area. 3. Scalability: Leaves room for future expansion, avoiding competition with other devices for server room space. III. Standards and Compliance 1. Industry standard requirements: Domestic standards such as the \"Data Center Design Code\" (GB50174) specify that the UPS battery room must be located separately and must meet requirements regarding fire protection, ventilation, load capacity, etc. International standards (such as TIA-942, Uptime Institute) also specify isolation requirements for data centers at different tiers. 2. Load-bearing capacity and infrastructure: The weight of battery packs is extremely high (up to several hundred kilograms per square meter); the floor structure in separate rooms should be designed to withstand such weight in order to avoid structural risks. Specialized fire protection: A gas extinguishing system designed for electrical fires (such as IG541 or heptafluoropropane) can be installed, instead of a conventional sprinkler system.
