Abstract
The invention relates to a magnetic operating mechanism, comprising vertically arranged struts and upper and lower cover plates fixed at the two ends of the struts, wherein an upper plate-shaped permanent magnet is embedded on the lower part of the upper cover plate; a lower plate-shaped permanent magnet is embedded above the lower cover plate; the same poles of the two plate-shaped permanent magnets are opposite; movable cores which are assembled on the struts through sliding up and down are arranged in the gap between the upper and lower cover plates; the movable cores are provided with magnet coils and a vertical power output shaft; and the power output shaft runs through the upper cover plate and the upper plate-shaped permanent magnet. The mechanism has the following beneficial effects that the mechanism has simple structure; the output shaft is not limited by movers and can provide high output instantly; the mechanism has less parts, so the mechanical failure probability is greatly reduced, thus avoiding the circuit breaker operating failure caused by the operating mechanism; and at the same time, the mechanism has the advantages of excellent shock and low temperature resistance, and is simple and reliable, is stable to operate and realizes real maintenance-free operation.
Description
Technical field
The present invention relates to a kind of high-voltage breaker operation mechanism, especially the electromagnetic operating mechanism of following primary cut-out of 10kV and contactor.
Background technology
At present, the operating mechanism that uses in primary cut-out, the contactor is hydraulic mechanism, pneumatic mechanism and spring mechanism normally, its complex structure of these operating mechanisms, parts are more, and along with the prolongation of service time, circuit breaker exposes increasing problem, wherein break down for operating mechanism more than 60%, with the leakage of oil of hydraulic mechanism, the dropout fault of the gas leakage of pneumatic mechanism and spring mechanism is main, has reduced the reliability of circuit breaker.Therefore, magnetic operating mechanism is paid close attention to by people at the bottom of the failure rate gradually owing to simple in structure.But existing magnetic operating mechanism is by being fixed on the mover that connects output shaft of solenoid controlled in the housing, controlling circuit breaker and carry out divide-shut brake, and the required electric current of this magnetic operating mechanism is bigger, and it is also high to consume energy.
Summary of the invention
The purpose of this invention is to provide a kind of magnetic operating mechanism, need the problem that electric current is big, power consumption is high to solve existing magnetic operating mechanism.
For achieving the above object, magnetic operating of the present invention mechanism comprises the pillar of vertical arrangement and is fixed on the upper and lower cover plate at pillar two ends, the below of described upper cover plate is embedded with upper plate shape permanent magnet, the top of described lower cover is embedded with lower plate shape permanent magnet, two plate shape permanent magnet homopolarity opposite disposed, be provided with the upper and lower moving iron core that is slidedly assemblied on the described pillar in the gap of described upper and lower cover plate, should be provided with solenoid and vertical power output shaft by moving iron core, this power output shaft is arranged on described upper cover plate and the upper plate shape permanent magnet.
Further, state unshakable in one's determination the pressure and be located at the solenoid both sides.
Further, the right and left outermost pillar of the pillar of described vertical arrangement is provided with slide rail.
The upper and lower cover plate of magnetic operating of the present invention mechanism is embedded upper and lower plate shape permanent magnet respectively, and to utmost point setting, has strengthened the gap between the upper and lower plate shape magnet, and the moving iron core and the big coil of bulk can be set, and has further improved power output; During use, the magnetic field interaction that magnetic field that the energising solenoid forms and plate shape permanent magnet form: an end attracts each other, one end repels mutually, makes solenoid do the upper and lower motion of straight line under the effect of making a concerted effort between the magnetic field that permanent magnet forms, and powerful power output is provided; In a deciliter position, by the sucking action of permanent magnet to iron core, mechanism can realize self-sustaining, having solved magnetic force mechanism needs the problem that electric current is big, power consumption is high, and this magnetic operating mechanism is simple in structure simultaneously, and power output shaft is not subjected to the restriction of mover, moment can provide greatly and exert oneself, and number of spare parts is few, and the mechanical breakdown probability reduces greatly, can avoid because the circuit breaker operation troubles that operating mechanism brings; Simultaneously, this magnetic operating mechanism has good antidetonation, low temperature resistivity energy, and simple and reliable, the stable operation of mechanism has been realized real non-maintaining operation.
