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: A reverse power connection preventing circuit includes a diode and an actuation unit that are connected in series between a positive input terminal and a negative input terminal of a circuit breaker. A positive electrode of the diode points to the negative input terminal of the circuit breaker, and a negative electrode of the diode points to the positive input terminal of the circuit breaker. When a power supply is forward connected to the circuit breaker, the diode is cut off, there is no current on the actuation unit, and the reverse power connection preventing circuit is in a power-off state. When the power supply is reversely connected to the circuit breaker, the diode conducts, and the actuation unit is configured to prevent closing of the circuit breaker, and/or the actuation unit is configured to perform an alarm prompt, to perform an early warning.
