The permanent magnetic electric control mechanism of vacuum circuit breaker is characterized in that the middle part of the static iron core is mounted with the symmetrical structure of two permanent magnets, the like poles of the two permanent magnets are directed toward the center, and the closing coil and the opening coil are mounted at the upper part and the lower part of the permanent magnets; wherein, the static iron core and the moving iron core are connected through the guiding ring, whereas the drive rod on the moving iron core is passed through the static iron core and is connected with an opening spring; the other end which is fixedly hinged with a crank arm can drive the moving contact of an arc-extinguishing chamber. The closing and opening operating mechanisms adopt permanent magnetic electric control mechanism, so that the permanent magnetic electric control mechanism of vacuum circuit breaker is widely applicable for the manufacture of vacuum circuit-breaker matching. The permanent magnetic electric control mechanism of vacuumcircuit breaker has the advantages of simple structure, fewer components, little space occupation, less energy consumption, good stability, high reliability, long service life, and maintenance free.
Description
The utility model provides a kind of vacuum circuit-breaker Permanent Magnet and Electric control mechanism, is widely used in making all kinds of vacuum circuit-breaker Permanent Magnet and Electric control mechanisms especially.
At present, circuit breaker closes, brake separating mechanism mainly contains electromagnetism and spring mechanism obtains to use.But be its supporting electromagnetism and this locker of spring, all exist more defective,, poor stability many as complex structure, part, reliability is not high, useful life is short, maintenance is big.
The purpose of this utility model is the defective that proposes at said mechanism, and a kind of brand-new supporting Permanent Magnet and Electric control mechanism of vacuum circuit-breaker is provided.Have simple in structure, part is few, it is little to take up room, power consumption less, good stability, reliability height, long service life, long-time running be non-maintaining.
The present utility model is taked following technical scheme: by automatically controlled 1, static iron core 2, moving iron core 3, guide ring 4, permanent magnet 5, closing coil 6, switching winding 7, drive rod 8 is formed, it is characterized in that: the middle part of static iron core 2 is installed with two permanent magnet 5 symmetrical structures, the magnetic pole of the same name of two permanent magnets 5 is towards the center, the upper and lower of permanent magnet 5 is installed with switching winding 7 and closing coil 6 respectively, wherein connect by guide ring 4 between static iron core 2 and the moving iron core 3, drive rod 8 passes static iron core 2 and links to each other with tripping spring on 4 pairs of moving iron cores 2 of fixed guide ring, and fixing hinge of the other end and connecting lever drives the empty moving angle head of arc extinguishing.Electronic Control driving circuit breaker is made a match, the separating brake motion but magnetic circuit has.
Advantage of the present utility model: it is supporting that it is widely used in all kinds of vacuum circuit-breakers, compare with spring mechanism with existing electromagnetic mechanism, no longer need other lock device, close, separating brake adopts the Permanent Magnet and Electric control mechanism, have simple in structure, part is few, it is little to take up room, power consumption little, good stability, reliability height, the life-span is long, long-time running is non-maintaining, for having released a kind of brand-new Permanent Magnet and Electric control mechanism in the vacuum circuit-breaker field.
Accompanying drawing is a sectional structure chart of the present utility model:
Describe in further detail below in conjunction with accompanying drawing: with reference to accompanying drawing electronic control circuit principle, U is a direct voltage among the figure, and C is a charge and discharge capacitance, pays magnetic energy, VT for operating mechanism provides
1, VT
2, VT
3Be three thyristor switchs, the conducting of control circuit and the flow direction of electric current, VD
1, VD
2Be fly-wheel diode, for coil inductance afterflow path is provided.
When circuit breaker is in the separating brake position, this moment VT
1Be in conducting state, VT
2, VT
3All in cut-off state.Direct voltage U is through VT
1Charge to electric capacity.When giving thyristor VT
3Base stage when applying triggering signal and making it conducting, the discharge loop conducting, capacitor C is through VT
3To closing coil 7 discharges, the moving iron core 2 of mechanism connects the fixing hinge of connecting lever via drive rod 8.Touch spring drives the circuit breaker motion and finishes feed motion.Remove VT this moment
3Triggering signal make it to end fly-wheel diode VD
2For the energy of inductance in the coil provides the afterflow path.In like manner, work as VT
2During conducting, capacitor C makes circuit breaker finish the separating brake action to switching winding 6 discharges.
