An intelligent low-voltage circuit breaker

Abstract

The invention relates to an intelligent low voltage circuit breaker. The intelligent low voltage circuit breaker is characterized in that it includesIncludes a lower computer module with data acquisition, transmission and execution functions and an upper computer module with receiving, processing information and command sending functions , the lower computer module and the upper computer module are separately arranged in a circuit board, the lower computer module includes an electric degree processing module for calculating an electric degree magnitude, an ignition current processing module for judging whether the ignition current exceeds a predetermined threshold value, a memory chip for storing various acquisition signals of a lower computer, a lower computer control chip MCU, a motor driving switch module for executing MCU instruction to complete switching operation, a leakage detection processing module, and an RS485 communication chip for communicating with the upper computer.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an intelligent low-voltage circuit breaker. Background technique [0002] The low-voltage circuit breaker has the characteristics of quickly cutting off the short-circuit current and being reusable, which greatly guarantees the safety of household electricity. However, the traditional low-voltage circuit breaker can only artificially set a disconnection threshold, and potential safety hazards can only be discovered through the disconnection of the voltage circuit breaker. When a leakage occurs in a household appliance that can be directly touched, it will pose a huge safety hazard to the user. At the same time, traditional low-voltage circuit breakers only have switching functions, and cannot dynamically detect various circuit parameters of corresponding electrical equipment. With the development of technology, the circuit module function integration technology o...
