Low-voltage intelligent circuit breaker, intelligent fusion terminal, master station and access method and system

The invention discloses a low-voltage intelligent circuit breaker, an intelligent fusion terminal, a master station and an access method and system, and the method comprises the steps: uniformly planning the communication addresses of the low-voltage intelligent circuit breakers according to the installation positions and number of the low-voltage intelligent circuit breakers, carrying out the analysis of the communication addresses of all low-voltage intelligent circuit breakers through the intelligent fusion terminal, and obtaining a hierarchical relation; and automatic association with the low-voltage intelligent circuit breaker is realized, so that self-adaptive access of the low-voltage intelligent circuit breaker is realized. And meanwhile, the master station can automatically generate graph and model information according to the hierarchical relationship of the low-voltage intelligent circuit breakers, so that the configuration workload of field operation and maintenance is reduced. 一种低压智能断路器、智能融合终端、主站
