The technical scheme employed by the utility model is that the tripping mechanism is characterized in that the tripping mechanism also comprises a reset spring; one end of the reset spring acts on a pedestal, and the other end of the reset spring acts on a reset piece; a shackle is fixedly provided with a force-bearing rod; the reset piece is provided with a boss which can drive the force-bearing rod to rotate; and a cavity, which is used for the swinging of the force-bearing rod, is disposed on the boss. Through the above scheme, the tripping mechanism provided by the utility model solves the problems in the prior art, and enables the reset force of the reset piece to be superposed to the tripping force of the mechanism, thereby improving the tripping speed and stability.
Description
Technical field
The utility model relates to a kind of RCD, refers to especially the tripping mechanism on RCD.
Background technology
In 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 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.Dropout actuating force provides by tripping coil completely, and dropout actuating force size depends on the parameter of tripping coil and sound iron core; Because having determined the supply voltage of electric leakage module, the environment for use of RCD there is unsettled situation; in the time there is low-voltage; may cause electric leakage module dropout actuating force smaller; during this time there is leak current fault and will likely occur that RCD can not disengagement failure power supply; or cut off situation not in time, can cause 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 utility model overcomes the problem that prior art exists; provide in the tripping force that a kind of reset force of using return unit is 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 utility model adopts following technology: the tripping mechanism on a kind of RCD, include base, tripping coil, return unit and snap close, wherein snap close is rotated 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, on described snap close, be fixedly installed force rod, on described return unit, be provided with the boss that can drive force rod to rotate, 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 utility model is, the first stage: tripping coil provides return unit and the snap close that pulling force makes mechanism to untie; Second stage: mechanism moves under tripping coil active force, snap close produces actuating force; Phase III: and then second stage, 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.
Further setting of the present utility model is: on described snap close, be also fixedly installed transmission arm and driving lever, wherein the top of driving lever is provided with U-shaped draw-in groove, and driving lever is connected by the moving iron core on U-shaped draw-in groove and tripping coil; On described snap close, be separately provided with snap fit, on described return unit, be provided with the Ka Tai that can coordinate with snap fit position reset part, on described base, be provided with guiding slippage chamber, 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, conflict on the bottom surface of cavity in back-moving spring one end, the other end is conflicted on the projection of base, on described return unit, be provided with spacing block set, on described base, be provided with spacing block set and form the spacing limit chamber coordinating of return unit.
By further setting, be the further optimization to the utility model product, the cooperation of action is more sensitive, further ensures to realize to improve the actuating force of mechanism and the object of mechanism kinematic speed.
Below in conjunction with drawings and embodiments, the utility model is described further.
