Through the scheme, the tripping mechanism solves the problems existing in the prior art, the reset force of the reset piece is overlapped to the tripping force of the mechanism, the tripping force of the overall mechanism is improved, and therefore tripping speed and stability are improved.
Description
Technical field
The present invention relates to a kind of RCD, refer to especially the tripping mechanism on RCD.
Background technology
In the electronic type RCD; the residual current acting function of product directly drives breaker portion to move to realize by the tripping mechanism of electric leakage module; while requiring dropout module quick action, energy to guarantee greatly electric leakage occurs in action, RCD can disconnect rapidly and accurately; thereby the disengagement failure power supply, the protection person and device security.
Under so background, the dropout actuating force that electric leakage module can provide becomes an important parameter, directly affects the residual current acting time of product and the reliability of residual current protecting function.
The mechanism of electric leakage module is different from the mechanism of circuit breaker type, does not possess energy storage device.The dropout actuating force provides by tripping coil fully, and dropout actuating force size depends on the parameter of tripping coil and sound iron core; Because the environment for use of RCD has determined that there is unsettled situation in the supply voltage of electric leakage module; when low-voltage occurring; may cause electric leakage module dropout actuating force smaller; leak current fault during this time occurs will likely occur that RCD can not the disengagement failure power supply; perhaps cut off situation not in time, can cause the electric leakage accident.
Will will address the above problem, can not improve simply the parameter of release, otherwise the impulsive force of the time electricity release work that can cause rated voltage is excessive, the life-span of RCD will shorten, and also can cause the waste on cost simultaneously.
Summary of the invention
The present invention overcomes the problem that prior art exists; in the tripping force that provides a kind of reset force of using return unit to be added to mechanism; improve the tripping force of whole mechanism, thus the tripping mechanism on the novel RCD of lifting trip speed and stability.
The present invention adopts following technology: the tripping mechanism on a kind of RCD; include base, tripping coil, return unit and snap close; wherein snap close rotates and is arranged on base by bearing pin; described return unit is movably arranged on base; it is characterized in that: also include back-moving spring; one end of this back-moving spring acts on base; the other end acts on return unit; be fixedly installed force rod on described snap close; be provided with on described return unit and can drive the boss that force rod rotates, the top of this boss is provided with the cavity that can swing for force rod.
By adopting such scheme, manner of execution of the present invention is that the first stage: tripping coil provides return unit and the snap close that pulling force makes mechanism to untie; Second stage: mechanism moves under the tripping coil active force, and snap close produces actuating force; Phase III: second stage and then, after return unit and snap close are triped, do reseting movement, this reseting movement produces momentum to snap close, thereby make screw-home movement speed faster, actuating force is larger, that is to say that the reset force of using return unit is added in the tripping force of mechanism, improve the tripping force of whole mechanism, thereby promote de-mouthful speed and stability.
The further setting of the present invention is: also be fixedly installed transmission arm and driving lever on described snap close, wherein the top of driving lever is provided with the U-shaped draw-in groove, and driving lever is connected by the moving iron core on U-shaped draw-in groove and tripping coil; Separately be provided with snap fit on described snap close, be provided with on described return unit and can coordinate with snap fit the Ka Tai of position reset part, be provided with guiding slippage chamber on described base, return unit is placed in this guiding slippage chamber, described return unit one side is provided with cavity, back-moving spring is placed in this cavity, back-moving spring one end is conflicted on the bottom surface of cavity, the other end is conflicted on the projection of base, be provided with spacing block set on described return unit, be provided with on described base with spacing block set and form the spacing limit chamber coordinated of return unit.
By further setting, be the further optimization to product of the present invention, the cooperation of action is more sensitive, further ensures and realizes improving the actuating force of mechanism and the purpose of mechanism kinematic speed.
Below in conjunction with drawings and embodiments, the present invention is described further.
