commercial power circuit breakers in the low-voltage power distribution cabinets PD-01 to PD-04 are connected with six load circuit breakers AT the lower end, the six load circuit breakers respectively carry out three-phase output power supply to common lighting distribution cabinets AL-01 to AL-07, overhaul socket distribution cabinets JX-01 to JX-07, double-power-supply switching cabinets AT-01 to AT-07, emergency power supply devices EPS-01 to EPS-07 and uninterrupted power supply devices UPS-01 to UPS-07;
the output end of the low-voltage power distribution cabinet PD-01 is respectively connected with an ordinary lighting distribution box AL-01, AL-02, AL-03, an overhaul socket distribution box JX-01, JX-02, JX-03, one end of a double power supply in a double power supply switching box AT-01 to AT-06, one end of a double power supply in emergency power supply equipment EPS-01, EPS-02 and EPS-03 and one end of a double power supply in uninterrupted power supply equipment UPS-01, UPS-02 and UPS-03;
the output end of the low-voltage power distribution cabinet PD-02 is respectively connected with one end of a double power supply in emergency power supply equipment EPS-04-EPS-07, one end of a double power supply in uninterruptible power supply equipment UPS-04-UPS-07, one end of a double power supply in a common lighting distribution cabinet AL-07 and a double power supply switching box AT-07;
the output end of the low-voltage distribution cabinet PD-03 is respectively connected with one end of a double power supply in emergency power supply equipment EPS-01, EPS-02, EPS-03 and EPS-07, one end of a double power supply in uninterruptible power supply equipment UPS-01, UPS-02, UPS-03 and UPS-07, one end of a double power supply in an overhaul socket distribution box JX-07 and a double power supply switching box AT-07;
the output end of the low-voltage power distribution cabinet PD-04 is respectively connected with the common lighting distribution boxes AL-04, AL-05 and AL-06, the overhaul socket distribution boxes JX-04, JX-05 and JX-06, one end of a double power supply in a double power supply switching box AT-01 to AT-06, one end of a double power supply in emergency power supply equipment EPS-04, EPS-05 and EPS-06 and one end of a double power supply in uninterrupted power supply equipment UPS-04, UPS-05 and UPS-06;
the common lighting distribution boxes AL-01 to AL-07 are internally provided with two groups of modes for supplying power, one group is that three-phase mains supply is directly led into a load end to supply power to the load through the closing of a mains supply breaker in a manual state, the other group is that three-phase power enters the mains supply breaker in an automatic state, and the FAS is forced to start a control contactor to be attracted, so that power is supplied to the load end;
two paths of three-phase mains supply in the dual-power switching boxes AT-01 to AT-07 are respectively connected to two ends of a dual power supply through a mains supply breaker and then output to a load end through the dual power supply, and when one path of mains supply fails, the dual power supply is automatically switched to the other end with the mains supply to continuously supply power to the load;
two paths of three-phase mains supply in the emergency power supply equipment EPS-01 to EPS-07 are respectively connected to two ends of a double power supply through a mains supply breaker, one path of output of the double power supply is directly transmitted to a load, and the other path of output is transmitted to an inversion part and then transmitted to the load; when the commercial power is normal, the commercial power directly supplies power to the load, and when the commercial power is powered off, the emergency power supply equipment starts the inversion module to supply power to the load;
when the mains supply input is normal, the UPS equipment UPS stabilizes the mains supply and supplies the regulated mains supply to a load for use, and the UPS is an AC mains supply voltage stabilizer and also charges a built-in battery; when the commercial power is interrupted, the UPS immediately converts the electric energy of the battery in the UPS into 220V alternating current through the inverter module for the load to use.
