Description
Technical field
The present invention relates to residual current action breaker field, more specifically, it relates to one
Plant the tripping mechanism of residual current action breaker.
Background technology
Residual current acting type breaker generally includes contact apparatus, control contact apparatus divides
The operating mechanism of disconnected/Guan Bi, control operating mechanism perform the tripping mechanism of dropout tripping operation,
This tripping mechanism is provided with trip shaft, and tripping mechanism need to control control by triggering this trip shaft
Operating mechanism processed performs dropout tripping operation could implement the dropout tripping operation of breaker.
In RCD, the residual current acting function of product is by leakage
The tripping mechanism of electricity module directly drives breaker portion action to realize, and wants in action
Ask that dropout module action speed is fast, energy residual current acting when guaranteeing to occur greatly electric leakage
Protector can disconnect rapidly and accurately, thus disengagement failure power supply, the protection person and equipment
Safety.
In this context, the dropout driving force that electric leakage module is provided becomes one extremely
Close important parameter, directly affect the reliability of product residual current protecting function.Thread off
Driving force is provided by energy storage device, and energy storage device driving force size depends on trip line
Circle and the parameter of sound iron core；Owing to the use environment of RCD determines
There is unstable situation in the supply voltage of electric leakage module, when low-voltage occurs, and can
Electric leakage module energy storage device driving force can be caused smaller, electric leakage event during this time occurs
Barrier it would be possible to occur RCD can not disengagement failure power supply, or cut
Disconnected situation not in time, can cause electric leakage accident.
The problems referred to above will be solved, it is impossible to improve the parameter of electrical apparatus release simply, otherwise can
When causing rated voltage, the impulsive force of electricity electrical apparatus release work is excessive, aftercurrent action protecting
The life-span of device will shorten, and will also result in the waste on cost simultaneously.

Under, described dynamic iron core withstands the first linkage portion, and described conflict boss is placed in recess, is used for
Limit dropout indication piece to move；When product generation leak current fault, described dynamic iron core pulls
Dropout trace rotates to dropout direction, and operating mechanism stirred by dropout boss, and breaker takes off
Button tripping operation, the most described conflict boss departs from recess, and dropout spring orders about dropout indication piece and stretches
Go out to thread off outside hole.
The present invention is arranged further: described conflict boss includes conflict head and is fixed on dropout and refers to
Show the conflict boss body on part, be provided with rake between conflict boss body and conflict head, institute
Stating the end face that conflict head and recess match is arc surface.
The present invention is arranged further: described first linkage portion, the second linkage portion and rotation section one
Arranging, described rotation section is placed between the first linkage portion and the second linkage portion, described first linkage
The angle of portion and the second linkage portion is more than or equal to 90 degree.
The method have the benefit that in normal operation, dynamic iron under electromagnetic system effect
The heart can withstand the first linkage portion of dropout trace, the recess of the first linkage portion and conflict boss phase
Coordinate, pin dropout indication piece；When product generation leak current fault, electromagnetic system produces enough
Dynamic iron core is inhaled in big magnetic field, and described dynamic iron core pulls dropout trace to turn to dropout direction
Dynamic, operating mechanism stirred by dropout boss, and circuit breaker tripping trips, and the most described conflict is convex
Platform departs from recess, and dropout spring orders about dropout indication piece and stretches out outside dropout hole, dropout indication piece bullet
After going out, dropout trace returns less than in situ, and at this moment breaker is released that trace is locked can not be closed
Lock, it is necessary to dropout indication piece is resetted, and confirm that being released trace pins dropout indication piece
Can normally close a floodgate, structure design advantages of simple；
Wherein dropout spring orders about dropout indication piece and stretches out outside dropout hole, and conflict boss is all the time with
One linkage portion is inconsistent, and relative first linkage portion is slided, and improves the promotion that dropout trace rotates
Power, can be effectively improved tripping force, thus promote trip speed and stability；
Recess cooperates with conflict boss, it is achieved the first linkage portion be connected with dropout indication piece and
Separate, owing to the side that recess is the first linkage portion is provided with the formation that caves inward, just
Formed in recess and manufacture, also allow for the first linkage portion simultaneously and install with dropout indication piece or tear open
Unload；
Described dropout boss stretches out and is connected with operating mechanism, dropout boss
In replacing transmission pivot pin to insert the operating mechanism of breaker and it is connected with it, its
On middle market, commonly used stainless steel cylinder makees transmission pivot pin, and transmission pivot pin inserts breaker
In snap close, reduce parts, it is simple to assembling, the most also improve the transmission of dropout gangbar
Efficiency.
