  "textContent": "A circuit breaker identification method and apparatus, and a device are disclosed, and are applied to a power distribution system. The power distribution system includes a backplane communication busbar and a circuit breaker. The backplane communication busbar includes at least one slot, 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 R1 is uniquely determined by using a series circuit including R1 and R2. The method includes: when a second interface of a first circuit breaker is plugged in the backplane communication busbar, obtaining a first voltage of the first circuit breaker; determining a voltage interval within which the first voltage falls; and determining, based on the voltage interval and correspondences between preset voltage intervals and slot numbers, a number of a slot in which the first circuit breaker is plugged. In this method, automatic identification of a circuit breaker access status of each slot in the backplane communication busbar is implemented.",
