Abstract
The utility model relates to a permanent magnet operating mechanism, which belongs to a permanent magnet operating mechanism of an operating switch, a breaker, etc. The utility model is mainly composed of an iron yoke, a permanent magnet, a coil, an armature iron, a drive rod, an auxiliary rod, a shaft liner, etc. in the operating precess, because forward and reverse electric impulse current can pass an operating coil, the synthesized attraction force is formed by a magnetic field established by the coil curl, the lamination yoke and the armature iron and the self magnetic field of permanent magnet; the armature iron is driven to move; the switch, the breaker, etc. can be directly or indirectly driven through the drive rod to do opening and closing motions.
Description
It is simple that the utility model belongs to mechanism, AC/DC, and running speed is fast, long service life, parts are few, the permanent-magnet manipulating mechanism of non-maintaining maintenance, and control is closed in the pass that can be used for electric switch, circuit breaker or valve etc.
Present some industry, as operating mechanism used in the distribution system exist complex structure, parts are many, failure rate is high, cost an arm and a leg, must often keep in repair.
The purpose of this utility model is to overcome above many defectives, provides that the few long service life of a kind of simple and reliable, parts, processing are cheap, the operating mechanism of non-maintaining maintenance.
The purpose of this utility model is achieved by the following technical solution: permanent-magnet manipulating mechanism mainly is made up of iron yoke 1, coil 2, permanent magnet 3, armature 4, drive rod 5, auxiliary rod 6, neck bush 7 etc.
Now carry out the operation principle explanation: when permanent-magnet manipulating mechanism is operated other switching mechanism (as circuit breaker) separating brake or closed a floodgate by permanent-magnet manipulating mechanism structure chart (Fig. 1), need by control unit give coil 2 (coil two be forward, reverse winding, also coil) forward and reverse short-time pulse electric current, after the short-time pulse electric current enters coil 2, armature 4, to produce a magnetic field of setting up by coil 2 in the air gap 8 between the iron yoke 1 (size of air gap is by the decision of divide-shut brake stroke), with the synthetic attractive force in permanent magnet 3 magnetic fields that produce own, make armature 4 motions and pass through drive rod 5 directly or indirectly drive switch or circuit-breaker switching on-offs; When armature 4 was finished the divide-shut brake position, permanent magnet 3, armature 4, iron yoke 1 one of composition had the high magnetic permeability magnetic circuit and firmly hold armature 4, and after promptly the divide-shut brake pulse current disappeared from coil 2, this magnetic flux can also provide the power that must hold armature 4.
This permanent-magnet manipulating mechanism can be used the AC and DC power supply, its control unit is according to concrete operating position configuration, also can on drive rod 7 or auxiliary rod 8, install mechanical pilot guide or contact additional, non-contact transducer provides the signal of telecommunication, these all can change according to customer requirements, do not describe in detail in this permanent-magnet manipulating mechanism.
The size of this permanent-magnet manipulating mechanism power is as long as do critical piece size, the coil turn of permanent-magnet manipulating mechanism suitably to increase to reduce.
Use novel content to be described further below with reference to accompanying drawing to this:
The utility model can be changed into two kinds of structures, a kind of square, a kind of column type.Here only introduce the square structure.
Fig. 1 is that one of the utility model is implemented the structural profile schematic diagram
Fig. 2 is a three-view diagram of implementing structure
The principle structure of permanent-magnet manipulating mechanism described in the utility model as shown in Figure 1 and Figure 2, it mainly is made up of iron yoke 1, coil 2, permanent magnet 3, armature 4, drive rod 5, auxiliary rod 6, neck bush 7.
Rectangle iron yoke 1 usefulness bolt 10 is fixed on two channel-section steels 11.The planar central up and down of iron yoke 1 respectively has a hole, and the aperture studs with neck bush 7; Air core coil 2 is to form with enamelled wire coiling on the skeleton made from insulating material 9, is contained in the top of iron yoke 1 inner space, and two square permanent magnets 3 are contained in the iron yoke 1, under the coil 2; Respectively there is a screw in the last lower plane central authorities of cuboid armature 4, are contained in the iron yoke 1, and thorough coil 2 hollow, in the middle of the permanent magnet 3, the end of thread of drive rod 7 passes the hole of the bushing cover of inlaying on the hole on the iron yoke, screws in the last hole of armature 4; The end of thread of auxiliary rod 6 passes the hole of the neck bush of inlaying on the hole under the iron yoke, the following hole of screw-in armature 4.
The utility model compared with prior art has the following advantages:
1. owing to having economized out the transmission of many groups linkage of existing mechanism, directly having operated structure by iron core Simply, actuating speed is fast, divides, closing time is short, transmission efficiency is high.
2. simple in structure, parts are few, machine driving reliability height, fault rate are extremely low.
3. few, the wearing and tearing of movement parts less, the life-span is long, easy to use, greatly save maintenance cost. Produce, fill Join precision, specification requirement is lower, production cost is low.
4. be easy to realize automatic control and remote control.
5. can be widely used in all kinds of switches, the divide-shut brake of the machinery of valve etc. is in power equipment Vacuum switch, breaker, on-load switch, contactor, oil-break, SF6 switch etc. close the class high-voltage switch gear.
