Title:
MINIATURE CIRCUIT BREAKER HAVING NOVEL CURRENT DETECTION ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2019/148617
Kind Code:
A1
Abstract:
Provided in the present invention is a miniature circuit breaker having a novel current detection assembly, comprising a circuit breaker main body and a novel current detection assembly, the novel current detection assembly comprising: Hall magnetic field sensors, a current detecting wire and a Hall magnetic field sensor detection circuit board; by means of a detecting Hall magnetic field sensor among Hall magnetic field sensors without magnetic cores detecting a magnetic field generated by the current detecting wire, and an environmental Hall magnetic field sensor detecting a background magnetic field in an environment, the detected differential values of the detecting Hall magnetic field sensor and the environmental Hall magnetic field sensor are processed to obtain a current magnitude, and the interference of the background magnetic field is excluded, such that the detected current is more accurate. Thus, the circuit breaker that is configured having the novel current detection assembly is accurately opened and closed.
