Description
Technical field
The invention belongs to Low Voltage Electrical Apparatus, are related to a kind of leakage protection module of residual current action breaker,
Particularly a kind of actuating mechanism of residual current action breaker.
Background technology
Residual current action breaker is to ensure Electrical Safety, carries out circuit and switches requisite equipment, energy
Electrical equipment and personal safety are protected enough.Residual current action breaker is except with the basic protection such as short circuit
Outside function, also with creepage protection function, when leakage current reaches rated value, conducting electromagnet coil is produced
Magnetisation field, band dynamic iron core motion, so as to back down lock, unlocks mechanism, while Jing driving levers drive chopper
Thread off and control movable contact and execution dropout tripping operation is separated with stationary contact, to ensure circuit safety.With common open circuit
Device is similar, and the tripping mechanism of residual current action breaker has a shared dropout part (trip shaft), respectively
Dropout protection (such as short circuit, overvoltage/undervoltage, residual current etc.) of kind of function all passes through triggering, and this shared takes off
Fastener could implement the dropout tripping operation of chopper, and the dropout of difference in functionality is protected with respective for triggering
The actuating mechanism of de- fasteners action.When residual current (leakage current) reaches rated value, remaining electricity is performed
The actuating mechanism of stream protection passes through to trigger dropout part (trip shaft) action in chopper, to cause chopper
Thread off and trip, this actuating mechanism generally includes solenoid, and is arranged between solenoid and trip shaft
Drive mechanism, the residual current trip action of solenoid passes to trip shaft by the drive mechanism.Should
It is understood that, configuration drive mechanism is not only for transmission action, but also because obtain threading off needed for transmission
Multiple performance key element, the size of such as suitable tripping force and direction, preferable trip speed and sensitivity etc.,
That is, the performance of actuating mechanism can be improved by the optimization design of drive mechanism.
Traditional actuating mechanism generally adopts tripping mechanism as the tripping coil of drive mechanism, i.e. residual current
The tripping mechanism of trigger action mechanism of (above-mentioned solenoid) elder generation is threaded off, then disconnected by the tripping mechanism triggering
De- fasteners action in the device of road, its advantage are to obtain preferable tripping force, but due to complex structure, de-
The transmission link pulled involved by making is more, causes trip speed slow, affects dropout sensitivity, production efficiency
It is undesirable with manufacturing cost.Another kind of existing actuating mechanism, as drive mechanism that is, is remained using dropout actuated piece
The tripping coil (above-mentioned solenoid) of aftercurrent first drives dropout actuated piece action, dropout actuated piece
Action triggers the de- fasteners action in chopper again, and its advantage is simple structure, and has the disadvantage that tripping force is little,
Because tripping force factor is in addition to the electromagnetic force of tripping coil without other auxiliary external force.Also a kind of existing leakage
The actuating mechanism of electric protection module, it employ rotatable dropout actuated piece, rectilinear movement return unit and
The first elastic component (stage clip) that return unit is moved up can be driven, it is (convex by the first auxiliary section on return unit
Rise portion) insertion dropout actuated piece on the second push rod on the second auxiliary section (through hole) cooperation, make dropout
Actuated piece remains stationary when not leaking electricity, drives dropout actuated piece to rotate by the traction piece of tripping coil during electric leakage,
The rotation causes the projection of the first auxiliary section to skid off from the second auxiliary section (through hole), and this is skidded off so that resetting
Part is moved up under the first elastic component (stage clip) effect, while so that acceleration dropout part on return unit (the
Two fillets) against the second push rod, its hope be by the return unit move up with it is described against, make plus
Fast dropout part (the second fillet) promotes the second push rod and drives dropout actuated piece to be rotated to dropout direction rapidly,
But in fact this hope cannot be realized.Because：Return unit is moved up with described against certainly
Determine acceleration dropout part (the second fillet) to promote the second push rod and drive the direction of dropout actuated piece rotation not
Desired dropout direction, but the direction in opposite direction with dropout, therefore, unless also existed undocumented
Other structures, first elastic component (stage clip) of this mechanism release energy for improve dropout actuating power,
Trip speed or dropout sensitivity cannot produce any beneficial effect.Especially this existing actuating mechanism
Dropout actuated piece only insert the second auxiliary section (through hole) structure for coordinating by the first auxiliary section (lobe)
It is insecure to carry out remains stationary, because this cooperation can not realize reliability of the dropout actuated piece when not leaking electricity
Positioning, when chopper be given a shock wait impact when can cause false tripping action.Additionally, this existing action machine
Attachment structure between the traction piece and dropout actuated piece of the tripping coil of structure is complicated, needs traction piece and dropout
Actuated piece has higher machining accuracy, and assembling and setting is difficult.
