Description

The driver module of residual current circuit breaker
Technical field
The present invention relates to breaker technical field, particularly relate to a kind of driver module of residual current circuit breaker.
Background technology
In existing domestic and international leakage type breaker of plastic casing, leakaging controller adopts the integrated circuit (such as M54133FP) that special electric leakage gathers usually, the actuating mechanism of circuit breaker push rod is driven then to adopt the pattern of self-priming coil, its operation principle is generally: send constant level after electric leakage Acquisition Circuit collects leak current fault signal and drive unipolar type controllable silicon, self-priming coil can be made after unipolar type controlled silicon conducting to obtain electric (power taking is alternate alternating voltage), self-priming coil obtain electric after produce magnetic field, by the dynamic iron core in magnetic field suction actuating mechanism, iron core is moved, dynamic iron core drives breaker mechanism thus makes breaker actuation in motion process, leakaging controller and self-priming coil losing electricity simultaneously.
Be self-priming coil due to what adopt in prior art, thus the voltage of drive coil is alternating current, and voltage is higher, at least more than AC45V; In addition, the scheme of integrated chip is adopted to make cost higher in prior art, and action sequence solidifies relatively, if circuit breaker tripping in the course of the work, single-phase silicon-controlledly just can not to end, conducting always, AC coil then continues energising, after continuing several seconds, coil can generate heat and cause scaling loss short circuit, thus causes circuit breaker phase fault, and circuit breaker is burnt, and make network system there is the harm of local phase fault, adopt the circuit breaker of the program can not be used in the occasion that circuit breaker has the requirement of rear inlet wire.
Summary of the invention
The object of the present invention is to provide a kind of driver module of residual current circuit breaker, the problem that the driver module in order to solve residual current circuit breaker in prior art easily causes circuit breaker short circuit, circuit breaker is burnt.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of driver module of residual current circuit breaker, comprise: extension spring, yoke and dynamic iron core, one end of extension spring is fixedly connected on an inwall of yoke, the other end of extension spring is connected on dynamic iron core, between the inwall that dynamic iron core and yoke contact relatively, be disposed with dividing plate and magnet, the axial location along extension spring is arranged with coil in parallel.
Further, also comprise support, support is provided with breaker mechanism.
Further, a termination of dynamic iron core is socketed with back-up ring, and interts in the bracket.
Further, dividing plate adopts DT4 pure iron.
Further, also comprise leakaging controller, leakaging controller drives other component working of the driver module of residual current circuit breaker according to the leak current fault signal production burst level gathered.
Further, leakaging controller unit adopts the microprocessor of 16 bit to realize.
The beneficial effect of employing the invention described above technical scheme is: the driver module adopting residual current circuit breaker provided by the invention, direct current (voltage is DC12V) can be connected under the coil microprocessor of 16 bit is controlled, and power as pulsed is powered, therefore, even if breaker mechanism tripping, coil also can not heating burnout short circuit, thus make circuit breaker and network system safer; In addition, because the leakaging controller in the present invention adopts the microprocessor of 16 bit to realize, therefore, user can according to the demand custom feature of oneself, by the DLL (dynamic link library) definition input of the microprocessor of 16 bit, the function exported and mode, thus it is more flexible that electric leakage is controlled.
