Abstract
The utility model relates to an integrated residual-current circuit breaker, comprising a housing, a handle, an operating mechanism, an arc extinguishing chamber, a binding post, a release, and a zero sequence mutual inductor. A front end of an iron core of the release is provided with a driving lever, and the other end of the driving lever is connected with the operating mechanism. The release is connected with the operating mechanism through the driving lever in a linkage manner. The release is provided with an indicating component. An end of the indicating component forms a mandril which is abutted against the driving lever, and the other end is connected with the release through a spring. A position of the housing corresponding to the indicating component is provided with a leakage indicating window. The indicating component which is linked with the release is disposed on the release, and the housing is provided with the indicating window to observe the position of the indicating component, and status of the release is determined by color of the indicating component observed through the indicating window, so that whether the breaker is disconnected because of electric leakage or short circuit is determined, and circuit fault is convenient to troubleshoot.
Description
Technical field
The utility model relates to a kind of residual current circuit breaker, especially a kind of integral type residual current circuit breaker.
Background technology
Existing residual current circuit breaker is generally on the basis of miniature circuit breaker, to splice an electric leakage module to form, this residual current circuit breaker only just can be seen break-make indication on miniature circuit breaker, and this indication can only be indicated the namely break-make of circuit of operating mechanism, can not indicate circuit breaker disconnect cause to be because due to short circuit or electric leakage, need to again investigate the fault circuit breaker that just can close, cause maintenance inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provides a kind of and can indicate circuit breaker disconnect cause, the integral type residual current circuit breaker of convenient maintenance.
For achieving the above object, the utility model adopts a kind of integral type residual current circuit breaker, comprise housing, handle, operating mechanism, arc-extinguish chamber, binding post, release, zero-sequence transformer, the iron core front end of release is provided with driving lever, the other end of driving lever is connected on operating mechanism, release is connected by driving lever and operating mechanism, on described release, be provided with indication piece, indication piece one end forms push rod and withstands on driving lever, the other end is connected with release by spring, and the position of the corresponding indication piece of housing is provided with electric leakage indication window.
Above-mentioned utility model is further set to arrange on described electric leakage indication window transparent electric leakage marker.
The utility model adopts said structure, indication piece with release interlock is set above release, and the position that indication window is observed indication piece is set on housing, by the color of the indication piece observed at indication window, determine the state of release, thereby the disconnect cause of judgement circuit breaker is electric leakage or short circuit, facilitates the investigation of fault.
The utility model is further set to described binding post and is connected by spot welding with wire.The connection that makes wire more firmly, less, the more reliable performance of resistance.
