Replace ups battery detailed process 1, the charging unit 2 # U stop running, remove the UPS batteries GB 'in series with the fuse FU. 2. A fuse at both ends FU5, C point and connected diode V (2CZ 200A / 800V) .3, check the wiring is correct evacuation battery fuse FU. 4. Remove the fuse FU5, check for -WOM cathode of the diode voltage of about 241V, Wansong ups battery, the anode of -WOM voltage of about 218V. 5. Disconnect SA1, remove the fuse FU3, FU4.6, start charging machine 2 # U, and nominal voltage to the DC bus by the charging unit 2 # U, Sichuan ups battery, battery GB 'Parallel powered by. 7, remove the old battery from the battery panel group GB, to the positive and negative leads, respectively charger 1 # U of positive and negative corresponding connector. 8, start charging machine 1 # U, so that voltage and assembly of old batteries in parallel after the 241V. 9, disable the charger 2 # U, battery GB 'short voltage down to about 235V. 10, co-SA1, charger 1 # U, the old battery GB, the new battery G B 'parallel power to the DC bus. 11, off SA3, the new battery GB 'demolition screen mounted to the battery. 12, and will be connected to both ends of the fuse FU5 V diode connected to both ends of the fuse FU3. 13, mounted fuse FU4, charger 1 # U, the old and new batteries in parallel power to the DC bus. 14, off SA1, the new battery-powered UPS via a diode V to the DC link. 15, mounted fuse FU3, V diode is shorted. 16, remove the old battery. 17, co-SA1, charger 1 # U with a new battery, in parallel to the DC bus. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Scope and replace ups battery UPS battery operating principle is to use a reverse check feature diode artificially make the old and new batteries (GB, GB ') there is a voltage difference, ups between the battery, the new battery GB' investment, old When the battery GB exit, by the diode as an electronic switch, the instantaneous power to the DC bus, thus avoiding the old battery pack voltage is generated due to the difference in the parallel process of circulation, to ensure the stability of the DC power supply. While avoiding the UPS battery replacement battery pack process due to interrupted power supply box DC bus DC bus without battery-powered, computer ups battery, which may cause the DC system is not reliable factors. For marine equipment, cable television, military equipment, emergency lighting systems, backup power supply, large UPS and computer standby power stations, electric wheelchairs, golf carts, electric forklifts, railroad systems, power stations, power system.
