The utility model discloses a set up spacing portion, at circuit breaker circuit break, be in the separating brake state and forbid when closing a floodgate, construct the thread off gangbar of linkage of locking through circuit breaker external mechanization, if the handle of operating breaker closes a floodgate by force, removing fastener's traction lever is supported by the spacing portion of the linkage of being threaded off, the direct thread slipping of circuit breaker, and the moving contact subassembly is failure to actuate, the unable combined floodgate, the security that has improved the circuit breaker.
Description
Technical field
The invention belongs to breaker technical field, specifically it is related to a kind of dropout locking mechanism of miniature circuit breaker
Structure-improved.
Background technology
Chopper is divided into primary cut-out and low-voltage circuit breaker by its range.Low-voltage circuit breaker also known as automatic switch,
It is commonly called as " air switch " and also refers to low-voltage circuit breaker, it is a kind of existing hand switch effect, can automatically carry out decompression again, owe
The electrical equipment of pressure, overload and short-circuit protection.It can be used to distribute electric energy, infrequently starts asynchronous motor, to power circuit and
Protection carried out by motor etc., when there are serious overloads or the fault such as short-circuit and under-voltage in them can automatic shutdown circuit, its
Function is equivalent to Fuse switch and combining of crossing underheat relay etc., and does not typically need to become after disjunction fault current
More parts, obtain a wide range of applications.
When circuit is short-circuited or transships, circuit breaker internal mechanism action, automatically threaded off, cut off circuit, electricity
After the failture evacuation of road, operable breaker closing, reclose circuit.But under special circumstances, such as fault is not also
Situations such as exclusion, chopper subordinate subscriber have arrearage, when not allowing to close a floodgate, has a kind of mode to be locked out the dropout connection of chopper
Moving part, makes chopper be in slide fastener state.But existing chopper, the fit clearance ratio between dropout STATEMENT OF FEDERALLY SPONSORED and dropout part
Larger, if now operating breaker carries out feed motion by force, chopper can first connect disconnection of threading off again, easy detonator circuit
Fault, is likely to result in personal safety accident under extreme case.
Utility model content
The purpose of this utility model be aiming at above-mentioned circuit breaker trip circuit do not allow close a floodgate when, operating breaker by force
Carry out feed motion, chopper can first connect disconnection of threading off again, easy detonator circuit fault, or even personal safety accident occurs
A difficult problem, provides a kind of structure-improved of the dropout locking mechanism of miniature circuit breaker, ensure that the direct slide fastener of chopper, moves and touches
Head assembly is failure to actuate it is impossible to close a floodgate, and improves the safety of chopper.
Technical scheme
In order to realize above-mentioned technical purpose, the changing of the dropout locking mechanism of a kind of miniature circuit breaker of this utility model design
Good structure, it includes circuit breaker handle, and circuit breaker handle is connected with mechanism assembly by kinematic link, and described mechanism assembly includes
Dropout STATEMENT OF FEDERALLY SPONSORED, dropout STATEMENT OF FEDERALLY SPONSORED be contained in gangbar it is characterised in that: be provided with limiting section in described dropout STATEMENT OF FEDERALLY SPONSORED, limit
Position portion can prop up draw bar 4 with dropout STATEMENT OF FEDERALLY SPONSORED motor process.
Further, described limiting section is arranged on the side corresponding to draw bar in dropout STATEMENT OF FEDERALLY SPONSORED, and limiting section includes tiltedly straight
Section and arc row section, draw bar can skid off limiting section along arc row section.
Further, described draw bar and dropout part link.
Beneficial effect
A kind of structure-improved of the dropout locking mechanism of miniature circuit breaker that this utility model provides, spacing by arranging
Portion, in circuit breaker trip circuit, be in gate-dividing state do not allow close a floodgate when, by circuit breaker external mechanism lock dropout STATEMENT OF FEDERALLY SPONSORED
Gangbar, such as the handle of operating breaker is closed a floodgate by force, and the draw bar of dropout part is released the limiting section support of STATEMENT OF FEDERALLY SPONSORED
Live, the direct slide fastener of chopper, moving contact component is failure to actuate it is impossible to close a floodgate, and improves the safety of chopper.
