Description
Technical field
The present invention relates to a kind of RCD, refer to the tripping mechanism on RCD especially.
Background technology
In electronic type RCD; the residual current acting function of product is realized by the tripping mechanism Direct driver breaker portion action of electric leakage module; when requiring that in action dropout module action speed is fast, energy is guaranteed greatly electric leakage occurs, RCD can disconnect rapidly and accurately; thus 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 breaker type, does not possess energy storage device.Dropout actuating force is provided by tripping coil completely, and dropout actuating force size depends on the parameter of tripping coil and sound iron core; There is unstable situation in the supply voltage that the environment for use due to RCD determines electric leakage module; when there is low-voltage; electric leakage module dropout actuating force may be caused smaller; during this time there is leak current fault and likely will occur that RCD can not disengagement failure power supply; or situation about cutting off not in time, can cause electric leakage accident.
Will will solve the problem, can not improve the parameter of release simply, otherwise when can cause rated voltage, the impulsive force of electricity release work 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 prior art Problems existing; a kind of reset force using return unit is provided to be added in the tripping force of mechanism; improve the tripping force of whole mechanism, thus promote the tripping mechanism on the novel RCD of 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 is rotated by bearing pin and is arranged on base; 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; described snap close is fixedly installed force rod; described return unit is provided with the boss that force rod can be driven 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 invention is, the first stage: the return unit that tripping coil provides pulling force to make mechanism and snap close are untied; 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, thus making screw-home movement speed faster, actuating force is larger, and the reset force that is using return unit is added in the tripping force of mechanism, improve the tripping force of whole mechanism, thus promote de-mouth speed and stability.
The further setting of the present invention is: described snap close is also fixedly installed transmission arm and driving lever, and wherein the top of driving lever is provided with U-shaped draw-in groove, and driving lever is connected by the dynamic iron core on U-shaped draw-in groove and tripping coil; Described snap close is separately provided with snap fit, described return unit is provided with the chuck that can coordinate position reset part with snap fit, described base is provided with guiding slippage chamber, return unit is placed in this guiding slippage chamber, described return unit 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, described return unit is provided with spacing block set, described base is provided with and forms the spacing limit chamber coordinated of return unit with spacing block set.
By further setting, be the further optimization to product of the present invention, the cooperation of action is more sensitive, ensures further and realizes improving the actuating force of mechanism and the object of mechanism kinematic speed.
Below in conjunction with drawings and embodiments, the present invention is described further.
