Abstract

The invention discloses a B-type residual current monitoring and action circuit breaker with wireless transmission function, comprising a circuit breaker and a leakage detection and execution module matched with the circuit breaker. The leakage detection and execution module includes a power supply unit, a core processing unit, a leakage current detection unit, a LoRa wireless unit and a trip control unit. The incoming end of the circuit breaker is connected to the power supply unit, and the low-voltage direct current output from the power supply unit is input to the core processing unit, the leakage current detection unit and the LoRa wireless unit respectively, and the outgoing end of the circuit breaker is connected to the trip control unit. The B-type residual current monitoring and operating circuit breaker with wireless transmission function disclosed by the invention solves the problem of limited application occasions caused by the vacancy of existing commercially available residual current operating circuit breakers, and improves the data detection and transmission functions of the circuit breaker , an opening and closing state detection circuit is added.

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 action circuit breaker with 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. Product family of residual current protectors. It plays an important role in the safety protection of low-voltage power grids, especially in rural low-voltage power grids. [0003] According to GB / T 22794, GB16916.1, GB16917.1, the common residual current is classified into A type, AC type and B type. The common types of residual current-operated circuit breakers in the domestic market are also A-type or AC-type, and B-type is a large vacancy. Type A or AC only performs action protection for AC or AC superimposed pulsating DC residual current components, while B type adds detection and p...
