Summary of the invention:
The purpose of this invention is to provide that a kind of novel structure is simple, the permanent-magnet manipulating mechanism of dependable performance, wear-resistant, non-maintaining, long service life.
Technical solution of the present invention is: a kind of permanent-magnet manipulating mechanism, it is characterized in that: static iron core is arranged, switching winding and closing coil are housed in the static iron core, between switching winding and closing coil, permanent magnet is housed, in switching winding, closing coil and permanent magnet, be coated with moving iron core, moving core ends is connected with the bar of exerting oneself, and said mechanism is controlled by a permanent-magnet manipulating mechanism electronic control circuit.
Switching winding described in the present invention and closing coil are contained in place, nearly two ends in the static iron core respectively.The permanent-magnet manipulating mechanism electronic control circuit is the bistable state control circuit.Combined floodgate circuits for triggering and separating brake circuits for triggering are arranged in the bi-stable permanent magnetism operating mechanism electronic control circuit, and a termination of combined floodgate circuits for triggering has charge circuit, and the other end is connected to the closing coil checkout gear; One termination combined floodgate circuits for triggering of separating brake circuits for triggering, the other end is connected to the switching winding checkout gear.
Beneficial effect of the present invention is:
1) overcome the intrinsic drawback of traditional electrical magnetic mechanism and spring mechanism, the machinery of having cancelled the divide-shut brake position takes off, fastener system, and the active force that is produced by permanent magnet remains on vacuum circuit-breaker and closes, on the separating brake position.Because moving component can directly link to each other with movable feeler lever, do not need during divide-shut brake or intermediate conversion bindiny mechanism that needs are less, a large amount of consumption of electric energy when minimizing is operated, and have only a moving component, can improve Mechanical Reliability greatly.The real non-maintaining function of circuit breaker that realizes.
2) during this permanent magnet mechanism divide-shut brake, along with moving of moving iron core, the active force that mechanism provides is increasing, the state that provides an effective power to make switch remain on branch or close by permanent magnetism is provided up to stroke, the load characteristic of its power producing characteristics and vacuum circuit-breaker is consistent, can obtain very desirable speed characteristics.
3) because the divide-shut brake characteristic of permanent magnet mechanism is only relevant with coil parameter, the divide-shut brake characteristic of permanent magnet mechanism can be controlled by electronics or microsystem, return and can split to close and carry out intelligence operation, realize the phase-splitting zero breaking by to speed characteristics and Based Intelligent Control.
4) simple in structure, life-span length, wear-resistant reaches more than 100,000 times mechanical endurance.

The permanent magnetic operating technology is a nineties world state-of-the-art technology, it adopts a kind of brand-new operation principle and structure, with world's advanced technology nineties in 20th century---" permanent magnetism " technology incorporates among the design, fundamentally overcome the intrinsic drawback of other operating mechanism, this mechanism substitutes four connecting rod running parts in other mechanism with permanent magnet, need not any mechanical energy and by the permanent magnet active force vacuum circuit-breaker is remained on to close, on the separating brake position.Reduced moving component, thus a large amount of consumption when having avoided other operating mechanism operation and the unfavorable factor that on/off switch position machinery is threaded off, fastener system caused.This mechanism is equipped with control system and realizes the desired repertoire of vacuum circuit-breaker on/off switch, and realizes intellectuality to a certain extent, realizes non-maintaining operation.
Very near the requirement of vacuum circuit-breaker, it can directly link to each other with vacuum interrupter the characteristic of permanent-magnet manipulating mechanism, and it is minimum that amount of parts is dropped to, and can improve the structural rigidity of product, helps to reduce the raising of contact bounce and just-off speed.Be mainly used on 12～35KV level vacuum circuit-breaker, mechanical endurance be 10 times of Medium voltage switch or circuit breaker or more than, in view of permanent magnet mechanism characteristics simple in structure, reliable, wear-resistant, non-maintaining etc., can be supporting with on-load switch and outdoor on-pole switch well, according to the different requirements of user, the principle of utilizing permanent magnet mechanism and arc control device directly to link to each other adopts electronics or Control System of Microcomputer, can produce synchronous phase-selecting switch.
Permanent-magnet manipulating mechanism is made up of seven major parts altogether: static iron core 1, for mechanism provides the magnetic circuit passage; Moving iron core 2 is topmost moving components in the entire mechanism, generally adopts the mild steel structure, is permanent magnet 3,4, needed power when providing maintenance for mechanism; Switching winding 5 and closing coil 6; Drive rod (bar of exerting oneself) 7 is mechanisms with the circuit breaker transmission mechanism between connect tie.
When circuit breaker was in combined floodgate or separating brake position, no current passed through in the coil, and the low magnetoimpedance passage that permanent magnet utilizes dynamic and static iron core to provide will move iron core and remain on upper and lower extreme position, and without any need for mechanical interlocking.When actuating signal, electric current in combined floodgate or the switching winding produces magnetic potential, the magnetic field superposition that magnetic field that is produced by coil in the dynamic and static iron core and permanent magnet produce is synthetic, moving iron core is together with the drive rod that is fixed in the above, under the effect of resultant magnetic field power, in official hour, finish the folding task with the speed drive Switch main body of regulation.The moving iron core of this mechanism is in two positions of stroke termination, do not need to consume and appoint with what energy and can keep, and traditional electromagnetic mechanism, moving iron core is an end that is maintained at stroke by the effect of spring, and at the other end of stroke, keep by mechanical lock buckle or electromagnetic energy.
From the above, permanent-magnet manipulating mechanism is by with electromagnet and permanent magnet special combination, realize the repertoire of conventional circuit breaker operating mechanism: replace traditional maintenance function that latching device is realized extreme position of taking off, energy needed when providing operation by the divide-shut brake coil by permanent magnet.
