Fecha de publicación: 28/07/2020 Fuente: Wipo "IOT" The utility model discloses an NB-IoT intelligent circuit breaker. The system comprises a circuit breaker, a control module, an NB-IoT data transmission module and a switch control module. The controlmodule, the NB-IoT data transmission module and the switch control module are all arranged in the circuit breaker. Wherein the NB-IoT data transmission module is electrically connected with the control module, the NB-IoT data transmission module is used for carrying out data exchange with a server, the switch control module is electrically connected with the control module, and the switch controlmodule is used for controlling switching-on and switching-off of a circuit breaker. The beneficial effects of the utility model are that the technical means of an NB-IoT wireless network is integrated into the circuit breaker through the NB-IoT data transmission module, thereby enabling a user to remotely control the switching-on and switching-off of the circuit breaker, reducing the waste of electric power resources, and being lower in maintenance cost and higher in use value.
