Description
Technical field
The utility model relates to a kind of circuit breaker tripping indicating device and a kind of circuit breaker with this circuit breaker tripping indicating device.
Background technology
Existing miniature circuit breaker generally all has short circuit and overload protection function; once be short-circuited or transship; circuit breaker will be threaded off; but at this time user often cannot judge occurred on earth short circuit or overload (unless disjunction large short circuit current, beyond can obviously being polluted on shell).For user, clearly know short circuit to have occurred or overload is significant.If overload can be excised the part power consumption equipment on this branch road, close a switch and just can normally use; But if short trouble just must find short dot, after fixing a breakdown, the circuit breaker that just can close, or change immediately circuit breaker.
Traditional circuit breaker as shown in Figure 1, this circuit breaker has fixed contact 11, moving contact 12, handle 13, magnetic release 16, the thermal overload release 17He M of mechanism, the moving contact 12 of this circuit breaker can manually boot by handle 13 (people is disjunction), also can automatically start by the M of mechanism.The M of mechanism comprises plate 15 and trip indicator 18.Handle 13 is couple to drive link 14 and forms toggle, release lever 19 is hinged on plate 15 and by magnetic release 16 and thermal overload release 17 and controls, when breaking down, make the link rod between plate 15 and drive link 14 disconnect, thereby make magnetic release 16 and thermal overload release 17 be independent of handle 13, thread off.Trip indicator 18 has the faulty indication mark zone 181 that is arranged in below (figure left side), and this faulty indication mark zone is for example red.Thermal overload release 17 comprises bimetal leaf, and electric current flows through from this bimetal leaf, and an end of this bimetal leaf is fixed to housing, the other end and the slide rail co-operation that is mechanically connected to release lever 19.When heat is threaded off, the effect by bimetal leaf to slide rail, actuation trip bar 19.Release lever 19 starts to rotate, and the balance of release lever 19 and plate 15 is broken, and the four-bar linkage structure of circuit breaker becomes five bar linkage structures.Under the effect of spring, the M of mechanism starts rotation, resultant motion makes projection 151 promote the protuberance of trip indicator 18 rears (below in figure), thereby trip indicator 18 moves down (left side in figure), like this, faulty indication mark zone 181 exposes by the window of opening on shell.When magnetic is threaded off, the electric current in the coil in thermal overload release 17 is greater than predetermined value, and thermal overload release is by the current excitation in coil, and moving iron core, to the direction motion of tripping actuating device, hits tripping actuating device, makes circuit breaker tripping.Now, release lever 19 starts to rotate, and the balance of release lever 19 and plate 15 is broken, and the four-bar linkage structure of circuit breaker becomes five bar linkage structures.Under the effect of spring, the M of mechanism starts rotation, resultant motion makes projection 151 promote the protuberance of trip indicator 18 rears (below in figure), thereby trip indicator 18 moves down (left side in figure), like this, faulty indication mark zone 181 exposes by the window of opening on shell.The situation that is disjunction for people, release lever 19 contacts all the time with plate 15, and breaker mechanism is four-bar linkage structure, and trip indicator 18 is not touched, so faulty indication mark zone 181 can not expose.
As can be seen here, traditional circuit breaker has fault indication function, can indicate fault disjunction and artificial disconnection.Yet, also not having at present a kind of circuit breaker tripping indicating device and artificially to disconnect three kinds of disjunction states by short trouble, overload fault indicates respectively, so after circuit breaker (particularly household circuit breaker) is threaded off, user often cannot know failure cause accurately, thereby make to investigate fault, becomes a great problem.
Therefore,, when circuit breaker tripping, how clearly indicating short trouble, overload fault and artificial disconnection becomes problem urgently to be resolved hurrily.
