Abstract: A communication power supply system includes an alternating current power distribution module, a rectifier module, a monitoring module, a direct current power distribution module, and a signal-driven collection board. The monitoring module sends a control signal to the direct current power distribution module by using the signal-driven collection board, where the control signal is used to control the closing or opening of a circuit in the direct current power distribution module. The communication power supply system uses the monitoring module to control the direct current power distribution module, to control whether to power on the loads connected to the direct current power distribution module.

Abstract: This application discloses a circuit breaker and a power distribution box, and relates to the field of communication device technologies. The circuit breaker includes a housing, a control apparatus, and a current signal collection mechanism, an operating mechanism, and a contactor mechanism that are disposed in the housing. The current signal collection mechanism has a first fixed contact and a second fixed contact that are electrically connected. The operating mechanism has a rotating part and a first moving contact. The first moving contact is electrically connected to a first electrode cable inlet port of the circuit breaker. Rotating the rotating part may make a circuit between the first moving contact and the first fixed contact connected/disconnected.

Abstract: In the power source switching control system, a circuit breaker includes a controller and an on/off apparatus. The controller controls, based on a signal of a monitor, the on/off apparatus to adjust an on/off state of a power source connected to the circuit breaker, that is, adjust, from an on state to an off state based on a switch-off signal of the monitor, a working power source that is currently working, and adjust a backup power source from an off state to an on state based on a switch-on signal of the monitor, to implement a process of power source switching between the working power source and the backup power source.
