Description
Technical field
The present invention relates to Low Voltage Electrical Apparatus, particularly relate to a kind of fault distinguishing indicating device of Pyromagnetic release.
Background technology
Pyromagnetic release is the important component part of breaker of plastic casing, and it plays the function of overload protection and short-circuit protection in whole circuit breaker, due to its stable performance, reliable, is widely used.The release of existing circuit breaker, while having overload current in circuit, thermal protective element bimetal leaf is heated and deforms, and promotes draw bar, and then makes operating mechanism action, open circuit; While having short circuit current in circuit, electromagnetic system produces electromagnetic force, and armature motion is moved draw bar, and then makes operating mechanism action, open circuit.But, in the prior art, after circuit breaker disconnects, what the reason that cannot indicate dropout is, it is (as overlond trip, short circuit are threaded off, manually disconnected or auxiliary disconnection) what reason makes its dropout, dropout reason can not be distinguished by indicating mechanism, and this gets rid of to further judgement and fault and has brought difficulty.So, just need a kind of fault distinguishing indicating device, make operator's failure judgement type intuitively, fix a breakdown in time.
Notification number is that the Chinese utility model patent of CN201238016Y discloses " circuit breaker with tripping indication function ", be characterized in having extended on housing hanging feet, display unit comprises indicating dial and return unit, indicating dial is hubbed on hanging feet and is corresponding with watch window, and indicating dial return unit contacts with indicating dial.If need to show respectively overload and short trouble, need to arrange two indicating dials, these two indicating dials are corresponding with two groups of draw bars and tripping respectively.Although this device has been realized dropout Presentation Function, carefully probes into, structural design is unreasonable, the first: complex structure, and parts are many, and Assembling Production is difficult for; It two is: after tripping is triped, in motion process, will drive indicating dial to rotate, overcome indicating dial back-moving spring power, slow down tripping movement velocity, and then extend drop-away time, the overall performance of circuit breaker is decreased.
Publication number is that the Chinese invention patent application of CN1819096A discloses a kind of " Thermomagnetic type release and dropout reason indicating device thereof ", the dropout reason indicating device of Thermomagnetic type release comprises: overload indicator and short circuit indicating device, wherein overload indicator comprises the first tripping, the first draw bar, the first draw bar back-moving spring, rotating shaft, bimetal leaf, bimetal leaf adjustment screw and joint cover, on described the first draw bar, has a hook, when release fastens, when be greater than default circuit breaker overload rating electric current by electric current, bimetal leaf is subject to the joint cover Bending Deformation after the raw or direct or indirect heat of miscarriage that powers on, make the screw on bimetal leaf promote the inclined-plane on the first draw bar, drive the first draw bar to be rotated counterclockwise, when the first draw bar rotates through after a little angle, hook on the first draw bar no longer hooks the first tripping, the first tripping under the effect that is subject to the first tripping back-moving spring towards the direction rotation of circuit breaker tripping is moved, the draw bar of impulse circuit-breaker operating mechanism makes circuit breaker tripping, show out as faulty indication due to the rotation of the first tripping the first tripping upper surface, indication fault reason is overload, described short circuit indicating device comprises the second tripping, the second draw bar, the second draw bar reset bullet Huang, rotating shaft, described yoke and armature, armature back-moving spring and joint cover, on described the second draw bar, has a hook, when release fastens, when be greater than default circuit breaker rated short circuit current by electric current, described magnetic is gripped the electromagnetic attraction action torque that described armature is produced and is greater than the moment of torsion that described armature back-moving spring produces street iron, make street iron towards the direction rotation motion that makes circuit breaker tripping, described street iron rotarily drive the second draw bar also towards the direction rotation motion that makes circuit breaker tripping, when the second draw bar rotates through after a little angle, hook on the second draw bar no longer hooks the second tripping, the second tripping is being subject to the effect of the second tripping back-moving spring equally towards the direction rotation of circuit breaker tripping is moved, the draw bar of impulse circuit-breaker operating mechanism makes circuit breaker tripping, show out as faulty indication due to the rotation of the second tripping the upper surface of the second tripping, indication fault reason is short circuit.This structure also can play the effect of distinguishing fault type, but its shortcoming is: faulty indication face is set directly in the first tripping and the second tripping, and the first tripping and the second tripping can not be located reliably at the postrotational stop position of threading off, thereby may cause the inaccurate or unreliable of faulty indication.
