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: 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.

Abstract: The control apparatus includes an electrical signal detection unit, a control unit, a contactor, a first execution unit, a protection unit, and a second execution unit. The electrical signal detection unit detects an electrical signal on a loop, and send the electrical signal to the control unit. The control unit generates a control signal, and send the control signal to the first execution unit. The contactor is connected to the loop. The first execution unit controls the contactor to be closed or opened, where when the contactor is closed, the loop is connected, and when the contactor is opened, the loop is disconnected. The protection unit detects a current value on the loop when the contactor is closed, where an opening instruction is sent to the second execution unit when the current value reaches a trip threshold. The second execution unit opens the contactor when receiving the opening instruction.

Abstract: A circuit breaker and a power distribution system are provided. The circuit breaker includes a housing and an internal element disposed inside the housing. The housing includes a front panel and a rear panel that are disposed opposite to each other, the front panel is disposed with a button, a status display unit, and a power wiring port, and the rear panel is disposed with a power interface and a signal interface. The power wiring port and the power interface are connected to a circuit of a power distribution system. The signal interface is internally and electrically connected to the button, the status display unit, and the internal element, and the signal interface is externally configured to be electrically connected to a control unit disposed outside the housing. A control signal of the control unit implements working of the button, the status display unit, and the internal element.
