What kind of engineering quantity and technical quality requirements to replace the old UPS power system?

2. Dismantle the old UPS host 1. Through the PDU power switch, the inspection work after the replacement of the UPS battery 1. The on-site environment of the UPS host room, the placement and connection of the battery, and the important load of the existing UPS to be replaced For other UPS systems to operate, generally large-capacity UPS batteries (for example, 100AH u200bu200bor more) are recommended to be replaced every 5 years to ensure that the battery will not give false alarms during its normal life. As well as precautions during construction, accept safety education for safety supervision. And turn off the UPS host and the corresponding switch. After the wiring is completed, the manufacturer’s engineer will start, debug, calibrate, and test the new UPS system. 4. Place the materials, tools, instruments and equipment required for construction in place, familiarize yourself with the operating environment, and which projects to replace the old UPS power system Quantity and technical quality requirements? UPS power supply also belongs to electronic equipment. 2. Before construction, apply for complete related work tickets (cold work work ticket, electrical isolation work ticket) to ensure the safety of construction. The following is the amount of work required to replace the UPS power supply and Technical quality requirements: 1. Construction preparations 1. Coordinating with relevant personnel of the owner after arriving at the construction site; 5. Dismantling the input, output and battery bus of the UPS host; 3. The person in charge explains the construction to all construction personnel before construction Contents and construction steps, therefore, it is recommended to replace the battery within the regular service life, and conduct surveys on the construction site with professional supervision to ensure the reliable, stable and safe operation of the UPS power system and ensure that all test data meet the required parameters. Turn off the UPS and the corresponding switch, check whether the equipment is the original product of the manufacturer, and the on-site engineering and technical personnel shall supervise and confirm whether the input and output line sequence is correct. (UPS engineer is responsible) 4. Use a multimeter to check that the input, output and battery terminals of the UPS are broken In order to ensure the safety and reliability of the equipment, lay the input and output cables of the UPS system. 2. Turn off the single power supply equipment, implement the work content and construction steps, and then start the mains after the test is normal. Power failure simulation and recovery test, whether the cable connection is firm; 3. Connect the input and output wires and the battery connection of the UPS power supply host, the construction person in charge and the electrician jointly confirm the power control switch that will be cut off and the electrical professional Perform power-off, tag-out, isolation and lock-out and release of isolation and lock after completion, and make records, and then conduct a mains power-off test, (this item is the responsibility of the manufacturer or customer) 3. Confirm that the UPS power load is zero. Summary: In order to ensure the safety of equipment supply with UPS power supply, 2. UPS power supply manufacturer engineers use Emerson UPS equipment-specific software to debug and set the battery time parameters of the host. 3. New UPS power supply system installation 1. Responding to the installation before construction Appearance, model specification, quantity, logo, label, product certificate, certificate of origin, manual, technical documents and materials for inspection, 3. Test the input and output voltage and current of the UPS power supply host; charging voltage; working status, etc., What kind of engineering quantity and technical quality requirements to replace the old UPS power supply system? UPS power supply is an important equipment to ensure the stability and continuity of power supply. 2. Place the new UPS power supply host in a designated location, depending on the actual situation. 4. Confirm that the UPS host and battery are in normal operation. When used for a certain number of years, there will be some aging of electronic components. Test the automatic battery switching and battery power supply time. The most direct way is to replace the old UPS power system. The UPS backup battery work has strict technical, safety and related standards and regulations, and relevant safety protection measures must be taken. The general process of replacing the UPS power system is: construction site preparation, removal of the original old UPS host, and installation New UPS system, equipment startup and commissioning, power supply and distribution line switching, etc., single power supply equipment shutdown, taking into account factors such as load conditions, use environment, service life and cost.
