Description
Technical field
The invention belongs to low voltage equipment technical fields, are specifically exactly to be related to a kind of circuit breaker failure tripping instruction machine
Structure can be conducive to user's accurate judgement breaker and be in artificial divide-shut brake or fault trip state.
Background technique
Breaker is divided into high-voltage circuitbreaker and low-voltage circuit breaker by its use scope.Low-voltage circuit breaker is also known as automatically switched,
It is commonly called as " air switch " and also refers to low-voltage circuit breaker, it is a kind of existing manual switch effect, and can carry out decompression automatically, owe
The electric appliance of pressure, overload and short-circuit protection.It can be used to distribute electric energy, infrequently start asynchronous motor, to power circuit and
The implementations such as motor protection, when serious overload or short circuit and the failures such as under-voltage occurs in they can automatic shutdown circuit,
Function is equivalent to Fuse switch and crosses the combination of underheat relay etc., and does not need generally to become after disjunction fault current
More components have had been widely used.
Existing miniature circuit breaker generally has the function of the instruction of handle divide-shut brake, when breaking down when open circuit, open circuit
Device can thread off, but it is artificial divide-shut brake or fault trip that user, which can not often determine that breaker disconnects, only biggish
Obvious pollution is had when short circuit current, on shell just can be with Judging fault situation, and for general short circuit current, on shell device
Do not have apparent pollution, can not Judging fault be that artificial divide-shut brake or short trouble cause, unfavorable malfunction elimination and maintenance.
Summary of the invention
Cannot be distinguished the purpose of the present invention is to existing circuit-breaker switching on-off is that artificial divide-shut brake or failure are de-
Technological deficiency caused by detaining, provides a kind of circuit breaker failure tripping indicating device, increases indicating fault for miniature circuit breaker
Function when breaker becomes gate-dividing state from "on" position in use, can pass through the indicator post in inspection hole
Judge whether this tripping is fault trip, after troubleshooting, breaker need to only be closed again, indicator can be automatic complete
At the switching from alarm condition to original state.
Technical solution
In order to achieve the above technical purposes, the present invention designs a kind of circuit breaker failure tripping indicating device, it includes tripping,
It is characterized by: the tripping be equipped with tripping boss, tripping boss in tripping rotation process can respectively with indicator
Front boss and rear boss contact, push indicator to move back and forth in the horizontal direction.
Further, the indicator is mounted in the installation sliding slot of circuit breaker base.
Further, in tripping shaft, tripping can be driven to rotate counterclockwise by dynamic contact mechanism to be made to jump for the tripping
Button boss is contacted with front boss.
Further, one end of the tripping connection connecting rod, the other end of connecting rod are connected on handle, and tripping can be in handle
Rotating clockwise under effect contacts tripping boss with rear boss.
Further, the dynamic contact mechanism is connected with reaction spring, by reaction spring thrust.
Further, the tripping is contacted in fault-free "on" position with lock fitting.
Further, the indicator is sliding block, and sliding block can slide in the installation sliding slot of circuit breaker base, indicator
Bit-avoiding slot is provided between front boss and rear boss, tripping boss is respectively and in front boss and rear boss contact process, tripping boss
It can extend into bit-avoiding slot.
Beneficial effect
A kind of circuit breaker failure tripping indicating device provided by the invention increases the function of indicating fault for miniature circuit breaker
Can, the effect using tripping to indicator when breaker becomes gate-dividing state from "on" position in use, can pass through
Indicator post in inspection hole after troubleshooting, need to only think highly of open circuit come whether judge this tripping be fault trip
It newly closes, indicator can be automatically performed the switching from alarm condition to original state.Entire mechanism need to only do existing breaker
Simple modifications can be realized, and structure is simple, improve breaker maintenance efficiency.

Specific embodiment
With reference to the accompanying drawings and examples, the present invention will be further described.
Embodiment
As shown in attached drawing 1~5, a kind of circuit breaker failure tripping indicating device, it includes tripping 1, and tripping 1 is equipped with tripping
Boss 101, tripping boss 101 can connect with the front boss 201 of indicator 2 and rear boss 202 respectively in 1 rotation process of tripping
Touching pushes indicator 2 to move back and forth in the horizontal direction.
The indicator 2 is mounted in the installation sliding slot 3 of circuit breaker base.
In tripping shaft 4, tripping 1 can be driven to rotate counterclockwise by dynamic contact mechanism 5 keeps tripping convex for the tripping 1
Platform 101 is contacted with front boss 201.
The tripping 1 connects one end of connecting rod 6, and the other end of connecting rod 6 is connected on handle 7, and tripping 1 can be in handle 7
Rotating clockwise under effect contacts tripping boss 101 with rear boss 202.
The dynamic contact mechanism 5 is connected with reaction spring 8, by 8 thrust of reaction spring.
The tripping 1 is contacted in fault-free "on" position with 9 fitting of lock.
The indicator 2 is sliding block, and sliding block can slide in the installation sliding slot 3 of circuit breaker base, the lordosis of indicator 2
Bit-avoiding slot 203 is provided between platform 201 and rear boss 202, tripping boss 101 was contacted with front boss 201 and rear boss 202 respectively
Cheng Zhong, tripping boss 101 can extend into bit-avoiding slot 203.
The course of work of entire mechanism is, when breaker breaks down tripping, tripping 1 and latches 9 mating surface and will divide
From tripping 1 will rotate counterclockwise around tripping shaft 4, while the stationary state of dynamic contact mechanism 5 is also destroyed, in counter-force bullet
Dynamic contact mechanism 5 is mobile to open position rapidly under the action of spring 8, to drive tripping 1, makes tripping boss 101 and indicator 2
Front boss 201 is in contact, and is moved downward after 2 stress of indicator to the position for exposing inspection hole, completes fault trip instruction.
After user's debugging, when the breaker for instruction of breaking down is closed a floodgate again, indicator 2 can smoothly be made to restore
To initial position.Specific method is after breaking down, and indicator is in alert locations, and breaker is in the state of separating brake.It pushes
Handle 7 makes breaker closing, to drive connecting rod 6, under the action of connecting rod 6, dynamic contact mechanism 5 is from open position to closing position
Movement is set, tripping boss 101 is in contact with 2 rear boss 202 of indicator in indicating fault position during the motion, indicates
2 stress of device moves right to initial position, completes switching of the indicator 2 from alert locations to initial position.
Divide-shut brake is carried out in the case where not breaking down tripping, tripping 1 will contact always with lock 9, tripping boss 101
It can not be contacted with the front boss 201 of indicator 2 and 2 rear boss 202 of indicator, therefore normal divide-shut brake not will cause indicator 2
Malfunction.
The present invention is the function that miniature circuit breaker increases indicating fault, and the effect using tripping to indicator is using
When breaker becomes gate-dividing state from "on" position in the process, it can judge that this is de- by the indicator post in inspection hole
Whether button is fault trip, after troubleshooting, only need to be closed again breaker, indicator can be automatically performed by alarm condition
Switching to original state.Entire mechanism, which only need to do simple modifications to existing breaker, can be realized, and structure is simple, and raising is resolved
Road device maintenance efficiency.
