Abstract: A power distribution system includes a backplane communication busbar and a circuit breaker. The backplane communication busbar includes at least one slot, and a first interface is configured in each slot. Each first interface is connected to a first resistor R1 having a different resistance value. A second interface of each circuit breaker is connected to a second resistor R2, and when the second interface of the circuit breaker is plugged in any first interface, a preset voltage interval corresponding to a resistance value of the first resistor R1 is uniquely determined by using a series circuit including the first resistor R1 and the second resistor R2.
