Description
Technical field
The invention belongs to low voltage equipment technical field, the most just relate to a kind of circuit breaker failure and thread off
Indicating mechanism, it is possible to be conducive to user accurately to judge that chopper is in artificial divide-shut brake or fault trip state.
Background technology
Chopper is divided into primary cut-out and low-voltage circuit breaker by its range.Low-voltage circuit breaker is also known as automatically
Switch, is commonly called as " air switch " and also refers to low-voltage circuit breaker, and it is a kind of existing hand switch effect, again can
Automatically decompression, under-voltage, overload and the electrical equipment of short-circuit protection are carried out.It can be used to distribute electric energy, infrequently
Ground starts asynchronous motor, and power circuit and motor etc. are carried out protection, when they occur serious overload
Or during the fault such as short-circuit and under-voltage can automatic shutdown circuit, its function is equivalent to Fuse switch with the most deficient
The combination of thermorelay etc., and typically need not change parts after disjunction fault current, obtain
It is widely applied.
Existing miniature circuit breaker typically has handle divide-shut brake instruction function, once break down open circuit time,
Chopper can be threaded off, but it is artificial divide-shut brake or fault trip that user often cannot judge that chopper disconnects,
Only when bigger short circuit current, shell has obvious pollution just can with Judging fault situation, and for
General short circuit current, shell device does not have significantly pollution, it is impossible to Judging fault be artificial divide-shut brake also
It is that short trouble causes, unfavorable malfunction elimination and maintenance.
Summary of the invention
The purpose of the present invention is aiming at existing circuit-breaker switching on-off and cannot be distinguished by artificial divide-shut brake or event
The technological deficiency that barrier dropout causes, it is provided that a kind of circuit breaker failure tripping indicating device, increases for miniature circuit breaker
Added the function of indicating fault, in use chopper from "on" position become gate-dividing state time, permissible
Judge whether this dropout is fault trip by the indicator post in inspection hole, when after failture evacuation,
Only need to again be closed by chopper, indicator can be automatically performed by alarm condition to the switching of original state.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of circuit breaker failure tripping indicating device, its bag
Include tripping, it is characterised in that: described tripping is provided with tripping boss, and tripping boss is in tripping rotation process
Can contact with front boss and the rear boss of indicator respectively, promote indicator to move back and forth in the horizontal direction.
Further, in described indicator is arranged on the installation chute of circuit breaker base.
Further, described tripping is contained in tripping rotating shaft, and tripping can be driven by dynamic contact mechanism and turn counterclockwise
Moving makes tripping boss contact with front boss.
Further, described tripping connects one end of connecting rod, and the other end of connecting rod is connected on handle, tripping energy
Enough rotating clockwise under handle effect makes tripping boss contact with rear boss.
Further, described dynamic contact mechanism connects has reaction spring, by reaction spring thrust.
Further, described tripping contacts with snap close laminating when fault-free "on" position.
Further, described indicator is slide block, and slide block can slide in the installation chute of circuit breaker base,
Having bit-avoiding slot between front boss and the rear boss of indicator, tripping boss connects with front boss and rear boss respectively
During Chuing, tripping boss can extend into bit-avoiding slot.
Beneficial effect
A kind of circuit breaker failure tripping indicating device that the present invention provides, adds indicating fault for miniature circuit breaker
Function, utilize the tripping effect to indicator, in use chopper is become separating brake from "on" position
During state, can judge whether this dropout is fault trip by the indicator post in inspection hole, when
After failture evacuation, only need to again be closed by chopper, indicator can be automatically performed by alarm condition to initial shape
The switching of state.Existing chopper only need to be done simple modifications and can realize by whole mechanism, simple in construction, improves
Chopper maintenance efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the present invention will be further described.
Embodiment
As shown in accompanying drawing 1～5, a kind of circuit breaker failure tripping indicating device, it includes tripping 1, tripping 1
Be provided with tripping boss 101, tripping boss 101 in tripping 1 rotation process can respectively with indicator 2
Front boss 201 contacts with rear boss 202, promotes indicator 2 to move back and forth in the horizontal direction.
Described indicator 2 is arranged in the installation chute 3 of circuit breaker base.
Described tripping 1 is contained in tripping rotating shaft 4, and tripping 1 can be driven by dynamic contact mechanism 5 and turn counterclockwise
Moving makes tripping boss 101 contact with front boss 201.
Described tripping 1 connects one end of connecting rod 6, and the other end of connecting rod 6 is connected on handle 7, tripping 1
Can rotate clockwise under handle 7 acts on makes tripping boss 101 contact with rear boss 202.
Described dynamic contact mechanism 5 connects has reaction spring 8, by reaction spring 8 thrust.
Described tripping 1 contacts with snap close 9 laminating when fault-free "on" position.
Described indicator 2 is slide block, and slide block can slide in the installation chute 3 of circuit breaker base, instruction
Have bit-avoiding slot 203 between front boss 201 and the rear boss 202 of device 2, tripping boss 101 respectively with lordosis
In platform 201 and rear boss 202 contact process, tripping boss 101 can extend into bit-avoiding slot 203.
The work process of whole mechanism is, when chopper breaks down dropout, and tripping 1 coordinates with snap close 9
Face will separate, and tripping 1 will rotate counterclockwise around tripping rotating shaft 4, and dynamic contact mechanism 5 is static simultaneously
State is also destroyed, and the effect lower moving contact mechanism 5 at reaction spring 8 moves to open position rapidly, from
And drive tripping 1, make tripping boss 101 contact with indicator 2 front boss 201, after indicator 2 stress
Move to expose the position of inspection hole to the left, complete fault trip instruction.
After user fixes a breakdown, when again being closed a floodgate by the chopper of instruction of breaking down, instruction can be made smoothly
Device 2 returns to initial position.Concrete grammar be break down after, indicator is in alert locations, chopper
It is in the state of separating brake.Driving handle 7 makes breaker closing, thus drivening rod 6, in the effect of connecting rod 6
Under, dynamic contact mechanism 5 is moved to closing position by open position, in motor process tripping boss 101 with
Indicator 2 rear boss 202 being in indicating fault position contacts, and indicator 2 stress moves right to just
Beginning position, completes indicator 2 by alert locations to the switching of initial position.
Carrying out divide-shut brake in the case of dropout of not breaking down, tripping 1 will contact all the time with snap close 9, jump
Button boss 101 cannot contact with front boss 201 and indicator 2 rear boss 202 of indicator 2, therefore normally
Divide-shut brake do not result in the misoperation of indicator 2.
The present invention is the function that miniature circuit breaker adds indicating fault, utilizes the tripping effect to indicator,
During use chopper from "on" position become gate-dividing state time, can be by the indicator position in inspection hole
Put and judge whether this dropout is fault trip, when, after failture evacuation, only chopper being closed again,
Indicator can be automatically performed by alarm condition to the switching of original state.Whole mechanism only need to be to existing chopper
Do simple modifications can realize, simple in construction, improve chopper maintenance efficiency.
