Problems solved by technology

The problem brought about by such a design is that since the strong current part circuit and the weak current part circuit are in the same closed case, the weak current part circuit is easily disturbed and affects its stability.
Also, when one part of the miniature circuit breaker fails, the entire unit must be replaced

Abstract

Provided is a miniature circuit breaker, which includes: a first module configured to measure the current and / or voltage of a line and send a measurement result signal, and disconnect the line according to a control signal; a second module configured to Sending the control signal according to the measurement result signal meeting a predetermined condition; and an interface, which respectively forms a pluggable connection with the first module and the second module, and is configured to be connected between the first module and the second module The measurement result signal and the control signal are transmitted between the second modules. By separating the strong current part circuit and the weak current part circuit of the miniature circuit breaker into separate modules, the two are connected by pluggable interfaces, so as to realize the modular design, which is conducive to independent production, separate assembly and expansion application.

Description

technical field [0001] Embodiments of the present disclosure relate to a miniature circuit breaker, and more particularly, to a modular smart miniature circuit breaker. Background technique [0002] Miniature circuit breakers (MCBs) are widely used in low-voltage power distribution devices and are used to cut off lines in the event of leakage current, short circuit, overvoltage, undervoltage and other fault conditions, thereby protecting users or electrical equipment. The currently used smart miniature circuit breakers have at least two functions: first, measure the voltage and / or current signal of the power line for monitoring and send a control signal when the line is judged to be faulty, so that the action of the circuit breaker The mechanism acts to cut off the fault line, thereby protecting the safety of users or electrical equipment. Second, information such as measured voltage and / or current signals and status of circuit breakers can be communicated for remote monito...
