Description
Technical field
The utility model relates to breaker technical field, is specifically related to a kind of residual current operated protective circuit breaker.
Background technology
Residual current operated protective circuit breaker is installed in low voltage electric network be used to provide indirect contact to protect to people; also can be used to prevent because of apparatus insulated damage; produce earth fault current and the fire hazard that causes; and can be used to the overload and the short circuit that distribute electric energy and protection circuit and power-supply device, also can be used as the use that the infrequently conversion of circuit and motor infrequently start.Now in low voltage electric network, vigorously promote the use residual current operated protective circuit breaker.It is simple to there is structure in residual current operated protective circuit breaker in the market, the defect that function is comparatively single, and the reclosing mechanism of existing residual current operated protective circuit breaker exists, and structural design is reasonable not, the defect of unstable properties.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides a kind of stable performance and is with residual current operated protective circuit breaker that is manual and automatic reclosing.
For achieving the above object, the utility model adopts a kind of residual current operated protective circuit breaker, comprise base, be arranged on the middle cover on base, the upper cover covered in being arranged on, described base is provided with circuit breaker handle, cover in described and be provided with circuit board, motor, reclosing mechanism, described reclosing mechanism comprises in rotating shaft that interlock is arranged on motor in elliptoid rotating disk, connecting rod, corresponding rotating disk place is arranged on the inserted link covered, one end of described connecting rod is arranged on the upper surface of rotating disk, the other end of this connecting rod is connected on described circuit breaker handle, described connecting rod is fixedly installed lever on the upper surface of one end of rotating disk, the upper surface of described inserted link is provided with the handle socket be exposed at outside upper cover, and the lower end of inserted link is provided with the manually point component matched with lever, described manually point component can rotate with inserted link and promote the divide-shut brake action that lever realizes circuit breaker handle.
Especially, in described upper cover, the side place of corresponding circuits plate is provided with loudspeaker, and these loudspeaker are electrically connected with circuit board, and on cover corresponding loudspeaker place and be provided with phonate hole.
The beneficial effects of the utility model are: this residual current operated protective circuit breaker by cover and be provided with manually and automatic reclosing brake mechanism, and this reclosing mechanism have structure simply, the advantage of stable performance.When electric machine rotation, the rotating shaft of motor drives dial rotation, dial rotation drivening rod, and connecting rod drives circuit breaker handle to realize reclosing action, namely realizes this residual current operated protective circuit breaker automatic reclosing function; When handle is inserted in handle socket by staff; and turning handle, handle drives inserted link to rotate, and the manually point component of inserted link lower end promotes lever action; lever drives circuit breaker handle to realize reclosing action, namely realizes the manual reclosing function of this residual current operated protective circuit breaker.And this residual current operated protective circuit breaker covers and is provided with loudspeaker, these loudspeaker can be reported the operating state of this residual current operated protective circuit breaker, remind operator safety operation.
