Title:
CIRCUIT BREAKER IDENTIFICATION METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/098183
Kind Code:
A1
Abstract:
Disclosed are a circuit breaker identification method and apparatus, and a device, wherein same are applied to a power distribution system. The power distribution system comprises a back plate communication busbar and a circuit breaker, wherein the back plate communication busbar comprises at least one slot, each slot is configured with a first interface, and each first interface is connected to first resistors R1, which have different resistance values; and a second interface of each circuit breaker is connected to a second resistor R2, and when the second interface of the circuit breaker is inserted into any first interface, a preset voltage interval corresponding to a resistance value of R1 is uniquely determined by means of a series circuit composed of R1 and R2. The method comprises: when a second interface of a first circuit breaker is inserted into a back plate communication busbar, acquiring a first voltage of the first circuit breaker; determining a voltage interval in which the first voltage is located; and according to the voltage interval and a correlation between a preset voltage interval and a slot number, determining the number of a slot into which the first circuit breaker is inserted. By means of the present method, the automatic identification of a circuit breaker access condition of each slot of a back plate communication busbar is realized.
