Description
Technical field
A kind of miniature circuit breaker is the utility model is related to, is to be related to dividing manually in a kind of miniature circuit breaker specifically
Lock kick component.
Background technology
Miniature circuit breaker is most popular a kind of terminal protection electrical equipment during building electrical terminal power distribution equipment is drawn.It is miniature
Breaker is made up of close/open machine, contact portion, protection device, arc quenching system etc..Its operation principle is：Utilize protection device
(electrical apparatus release) and electrical current heat component realize overload and short-circuit protection, when the electric current that the coil in electrical current heat component passes through is more than setting
Current value when, magnetictrip dynamic iron core action, promote strike bar hit operating mechanism, unlock operating mechanism, make to break
Road device separating brake and then disconnecting circuit, so as to realize overload and short-circuit protection to circuit.After fault is discharged, then by dividing
Switching-on mechanism carries out closing operation so as to connect circuit.At present, most miniature circuit breakers that China uses now are manual point
Combined floodgate formula, manually stir close/open machine can and make-break operation is carried out to circuit.Manual divide-shut brake formula miniature circuit breaker
