Abstract

The invention discloses a B-type residual current monitoring and actuating circuit breaker with a wireless transmission function. The B-type residual current monitoring and actuating circuit breaker comprises a circuit breaker and an electric leakage detection and execution module matching the circuit breaker. The electric leakage detection and execution module includes a power supply unit, a coreprocessing unit, an electric leakage current detecting unit, a LoRa wireless unit, and a trip control unit. The inlet wire end of the circuit breaker is connected to the power supply unit. The low-voltage DC power output by the power supply unit is input into the core processing unit, the electric leakage current detecting unit and the LoRa wireless unit. The outlet wire end of the circuit breaker is connected to the trip control unit. The B-type residual current monitoring and actuating circuit breaker with the wireless transmission function solves the limitation on application caused by thelack of the types of conventional residual current actuating circuit breaker on the market, and improves the data detection and transmission function of the circuit breaker, and is additionally provided with an on / off state detection circuit.

Description

technical field [0001] The invention belongs to the technical field of residual current protectors, in particular to a B-type residual current monitoring and operating circuit breaker with a wireless transmission function. Background technique [0002] China's residual current protectors began to develop in the mid-1970s, and were first popularized and applied in rural low-voltage power grids. After continuous improvement and development from the 1980s to the 1990s, a product with complete varieties, complete specifications, and IEC international standards has been formed. Product range of residual current protectors. It plays an important role in the safety protection of the low-voltage power grid, especially in the safety protection of the rural low-voltage power grid. [0003] According to GB / T 22794, GB16916.1, GB16917.1, the common residual currents are classified into A type, AC type and B type. The common types of residual current operated circuit breakers that are ...
