Wiring circuit for UPS bypass standby power supply

The invention discloses a wiring circuit for a UPS bypass standby power supply. The wiring circuit comprises a first UPS, a second UPS, a main circuit power supply line and a standby power supply line, wherein the main circuit power supply line and the bypass power supply line supply power to the first UPS and the second UPS respectively. First UPS output and second UPS output form UPS parallel connection output sequentially through parallel connection of a first UPS output connection indicating lamp and a second UPS output connection indicating lamp and through parallel connection of a first UPS output connection breaker and a second UPS output connection breaker. The UPS parallel connection output supplies power to a load. A manual bypass input circuit is connected with a second UPS bypass power supply. A manual bypass output circuit is connected with the UPS parallel connection output. A manual bypass connection breaker is arranged between the manual bypass input circuit and the manual bypass output circuit. According to the wiring circuit, a UPS power supply output circuit is connected with a mains supply line, and therefore two power supply modes are effectively combined, uninterruptible power supply between the UPSs and the mains supply is achieved, and electric power supply can be switched and kept standby between the circuits of the two power supply modes.
