Title:
MINIATURE CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2017/166797
Kind Code:
A1
Abstract:
A miniature circuit breaker comprises a housing having an air outlet. A plurality of arc splitter plates are installed in an arc chute. The arc chute is fixedly connected to the housing. An air discharge opening is provided on a back plate of the arc chute. A back arc splitting structure is disposed between the air discharge opening of the arc chute and the air outlet of the housing. The back arc splitting structure comprises a plurality of air flow channels disposed between the air discharge opening of the arc chute and the air outlet of the housing to enable high-temperature air flows first to pass through the air discharge opening and the plurality of air flow channels and then to be discharged from the air outlet. The embodiment prevents the air flows flowing out between the arc splitter plates from interrupting with each other, can effectively prevent hot air flows from interrupting with each other at the air outlet, and quickly dissipate heat energy, thereby quickly extinguishing electric arcs, enhancing an arc extinguishing capability of an arc extinguishing system and a current interruption capability of the circuit breaker, and reducing a size of the arc chute.
