Description

Circuit breaker

Technical field

The utility model relates to a kind of circuit breaker, and more particularly, it relates to the circuit breaker that a kind of energy oneself detects.

Background technology

Circuit breaker refers to the electric current that can close, carry and cut-off under normal loop condition, and can close, in official hour, carry and cut-off the switching device of the electric current under abnormal loop condition (comprising short circuit condition).

Circuit breaker can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out to protection, can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And after disjunction fault current, generally do not need to change parts.

At present, conventional circuit breaker on market, it comprises Shell of circuit breaker, operating mechanism, conductor structure, arc-control device, trip gear, by operating mechanism, make circuit breaker internal conductor structure path, when circuit abnormality, by trip gear cutoff circuit, the electric arc of generation is by arc-control device arc extinguishing.Although this circuit breaker is simple and practical, be widely used, generally can not oneself detect.

Utility model content

The deficiency existing for prior art, the circuit breaker that provides a kind of energy oneself to detect is provided the purpose of this utility model.

For achieving the above object, the utility model provides following technical scheme: a kind of circuit breaker, comprises Shell of circuit breaker, operating mechanism, conductor structure, arc-control device, trip gear, described trip gear comprises circuit module, magnet exciting coil, elastic mechanism, slide mechanism, described operating mechanism comprises for sending the sense switch of self-detection signal and the main switch cut-offfing for controlling circuit breaker, described circuit module and magnet exciting coil, conductor structure is electrically connected to, and integrated sense switch, main switch and for showing the LED light of working state of circuit breaker, described slide mechanism comprises slip rail, the magnetic sliding shoe that can slide along slip rail, contact chip with sliding shoe interlock, described conductor structure comprises input section and the deferent segment being separated by sliding shoe, described input section relative sliding Kuai one end is provided with for contact the upper contact of conducting with contact chip, described deferent segment relative sliding Kuai one end is provided with for contact the lower contact of conducting with contact chip, and described sliding shoe joins by elastic mechanism and magnet exciting coil.

By adopting technique scheme, sense switch sends self-detection signal to circuit module, if circuit breaker is normal, circuit module is controlled magnet exciting coil and is produced magnetic force, attracts sliding shoe to move to magnet exciting coil direction, and contact chip is engaged with upper contact, lower contact, major loop is closed, produce a new signal of telecommunication, the signal of telecommunication feeds back to circuit module, controls LED light and shows that circuit breaker is normal; If circuit breaker is undesired, major loop cannot be closed, without the signal of telecommunication, produces, and circuit is confiscated feedback signal, controls LED light and show that circuit breaker is undesired.

The utility model is further set to: described sense switch is point driving switch.

By adopting technique scheme, prevent that the circuit breaker causing because of misoperation is always closed.

The utility model is further set to: a top cover of being made by transparent material is stamped at described Shell of circuit breaker top.

By adopting technique scheme, when preventing misoperation, can see intuitively the operating state of circuit breaker.
