Preferably, the bypass system is composed of a plurality of UPS modules 9, and the plurality of UPS modules 9 simultaneously supply power to one electrical appliance.

Each UPS module 9 of the bypass system adopts an independent control system, the UPS modules 9 are independently controlled according to the shared information, and the fault module can be immediately separated from the parallel operation system after being out of service, so that the parallel operation system is not damaged; each UPS module 9 in the bypass system is internally provided with an automatic bypass switch and a corresponding bypass current-sharing inductor, so that the current-sharing performance of bypass power supply of the system is good; the UPS module 9 in the system can share the battery, the number of the battery is not limited by the number of parallel machines, the number of battery configuration is greatly reduced, and a user can completely configure the battery according to the backup time; when the SNMP card is selected, the remote monitoring of the UPS integrated system can be realized; and the maintenance bypass function can be switched to the maintenance bypass for power supply when an emergency occurs, and maintenance personnel can safely maintain the system on line.

As shown in fig. 1, the main bypass of the UPS is split, and the bypass power is sent to each UPS module 9 through the bypass inductor to realize distributed bypass output. The main circuit power supply and the battery are sent to each UPS module 9 through copper bars. The 10 UPS modules 9 share one output air switch 15. In the service bypass state, the bypass power is directly output through the service bypass air switch 36.

As shown in fig. 3, each UPS module 9 has a bypass air switch 36 and a main bypass air switch 32. When the bypass air opening 36 is closed, the bypass power to the cabinet is fed to the UPS module 9.

If the bypass voltage, the frequency and the phase sequence are normal, the inverter voltage tracks the bypass power supply and then is switched to the inverter output without interruption, otherwise, the UPS module 9 is switched to the inverter 40 to output intermittently. The inverter indicator light is on, the bypass indicator light is off, and the UPS inverter 40 supplies power and outputs. If the battery is normal, the UPS module 9 will initiate the charger to charge the battery.
