UPS power supply is one of the equipment that is prone to fire in the computer room, in the daily maintenance of the computer room, we must pay attention to the maintenance of the UPS and be equipped with the corresponding fire extinguishing system.
1 Fire extinguishing facilities
The UPS battery room should be equipped with a gas fire extinguishing system or a water mist fire extinguishing system. When using a pipe network gas fire extinguishing system, the battery room should be equipped with two independent fire detectors at the same time, and the fire alarm system should be linked with the fire extinguishing system. When the fire extinguishing method is fully submerged, the fire extinguishing system controller should control the dampers and dampers in the room to close the dampers and dampers in the room before the fire extinguishing equipment is activated, stop the air conditioner and exhaust fan, and cut off the non-fire power supply. When using lithium batteries, the battery room should be equipped with an automatic sprinkler fire extinguishing system. Compared with commercial or industrial use, medical institutions have higher standards for UPS uninterruptible power supply protection systems. Most of the electricity loads in hospitals are primary and secondary loads, which have high requirements for power supply continuity and reliability. Air conditioning system equipment is the main power-consuming equipment in hospitals and needs to be managed in key management of power use. Class II medical places have high requirements for power supply continuity and reliability, and need to be comprehensively monitored. Important medical technology laboratory equipment is sensitive to power quality and needs to be paid attention to.
The UPS equipment room should be equipped with fire extinguishers and comply with the relevant provisions of the "Building Fire Extinguisher Configuration Design Code" GB50140.
2 Alarm device
The UPS equipment room should be equipped with an automatic fire alarm device, and the alarm signal should be directly connected to the fire control room, and comply with the relevant provisions of the "Design Code for Automatic Fire Alarm System" GB50116. The primary factor in the selection of UPS uninterruptible power supply for medical equipment is high stability and reliability. Most of the medical equipment belongs to precision instruments, the power continuity requirements are very high, and the quality of power quality determines whether the medical equipment can operate normally, especially large and specific high, fine and cutting-edge medical equipment has strict requirements for power quality.
The area where the gas fire extinguishing system is set up should be equipped with a fire alarm device, a fire extinguishing display light should be set above the outer door of the area, and the control box (cabinet) of the fire extinguishing system should be set up in a place outside the room that is easy to operate, and there should be a protective device to prevent misoperation. The needs of the medical industry are far beyond the data room. Mobile information solutions in the medical industry also require a safe and stable UPS uninterruptible power supply. For precision instruments such as CT machines, MRI machines, surgical auxiliary machines, etc., power frequency online UPS power supply can be used to provide protection. UPS is an online dual-conversion UPS with zero conversion time, online mode efficiency up to 96%, and a variety of communication interfaces can be linked with medical equipment. 3 sets of output sockets are independently controlled to manage a variety of medical equipment to be turned on and off in different sequences.
3 Electrical safety
UPS UPS has the performance advantages of low heat loss, low noise, small size and long life. In addition, due to the modular design, NT series UPS greatly reduces the mean time to repair (MTTR) and makes maintenance easier. Through the digital design of microprocessors, complex analog circuits are simplified and the number of parts is greatly reduced, making the overall system safer and more reliable. It provides reliable power guarantee for key facilities such as operating rooms, ICU intensive care units, and CCU cardiac care units. It fully takes into account the flexible expansion requirements required for the future business development of the hospital. The lighting lines of the UPS equipment room (including when laid in the ceiling) should be laid through metal casings or closed metal ducts, and the metal casing or trunking should be fire-protected. The battery room should use explosion-proof lamps, ventilation motors, and air conditioners, and switches, sockets, and distribution boxes should be strictly prohibited in the battery room.
Different use environments, different application loads, and different operators have different requirements for the functional characteristics, performance, technical indicators, operation methods, and even volume and weight of UPS uninterruptible power supply protection systems. UPS power supplies help hospitals create green information channels to further improve the hospital's business level and service quality. The cable lead wire of the battery pack should be threaded through a metal sleeve, and the lead end of the sleeve should be close to the output end of the battery. The outer periphery of the metal pipe should be coated with anti-acid (alkali) paint, and the sealing area should be sealed with anti-acid (alkali) material. The bending radius of the cable should meet the requirements of cable laying, and the height of the cable through the cable exposed to the ground can be lower than the output terminal of the battery by 200mm-300mm.
The metal shell, various metal pipes, metal trunking, building metal structures, etc. of all equipment in the UPS equipment room must be connected and grounded at an equipotential, and the grounded connection wire should have sufficient mechanical strength and chemical stability.
