Abstract

The invention discloses a circuit breaker with wireless communication. The circuit breaker comprises a first insulating shell and a second insulating shell which are arranged in parallel. At least one of overload or short circuit protection devices, a first operating mechanism, a first contact system and an arc extinguishing system are arranged in the first insulating shell. A second operating mechanism, a second contact system, an electric operating mechanism and at least one electronic circuit board are arranged in the second insulating shell. The circuit breaker is characterized in that a second cavity formed in the second insulating shell is larger than a first cavity formed in the first insulating shell, and the electronic circuit board is arranged in the second cavity, and the circuit breaker is at least provided with a power supply module and a control unit, and further comprises a first wireless communication unit. According to the circuit breaker with wireless communication, control signals of peripheral equipment can be received through the wireless communication unit, and remote switching control over electric equipment is achieved.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a circuit breaker with wireless communication. Background technique [0002] At present, with the development plan of the State Grid for the smart grid, the smart energy meter has become one of the key products in the construction of the smart grid. a wide range of applications. The existing external circuit breaker of the electric energy meter with automatic closing and opening meets the prepayment control function and automation degree of the smart electric meter to a certain extent. However, the external circuit breaker of the electric energy meter in the prior art is mainly connected to the electric energy meter by wire, and the automatic closing and opening of the circuit breaker is controlled by the level signal. There are large hidden dangers, and there is a lack of functions such as data interaction between the energy meter and the circuit breaker, and t...
