The utility model can be used to control the switch of power supply or distribution network, the contactor, the breaker or the valve, etc. The utility model consists of a closed magnetic circuit consisting of a conduction shaft (1), an upper magnetic yoke cover plate (2), a cylindrical moving core (3), a U-shaped outside magnetic yoke (4), a cylindrical static iron core (5), a ring-shaped permanent magnet (6), and an electromagnetic coil (7).
Description
Technical field
It is simple in structure that the utility model belongs to, AC/DC, movement velocity is fast, economize on electricity, parts are few, volume is little, cheap, the electromagnetism actuating permanent magnetism maintaining body of long service life and non-maintaining maintenance, what be applicable to low pressure confession, distribution system switch, contactor, circuit breaker or valve etc. closes, divides the control field.
Background technology
What widely apply in low pressure confession, distribution system at present is traditional AC and DC contactor, the AC and DC circuit breaker.During the work of the operating mechanism of this class low-tension switch electric appliance by electric energy maintenance, complex structure, parts are many, failure rate is high, must often keep in repair.The AC and DC contactor is given in the development of sintered Nd-Fe-B permanent magnetic material, and wide space has been opened up in the innovation of AC and DC breaker operation mechanism.Disclosed in recent years Chinese patent has: many utility models such as ZL98232979.2, ZL99209050.4.Technically traditional operating mechanism has been carried out bigger improvement, but it is simple not to the utmost still to exist structure, the shortcoming that the magnetic circuit parts are on the high side.
The utility model content
The purpose of this utility model is to overcome above-mentioned many shortcomings, provide a kind of more simple and reliable, parts still less, be convenient to processing and manufacturing, cheap, long service life and can not change traditional contactor, case for circuit breaker size and dimension directly substitutes traditional operating mechanism with new operating mechanism.
For realizing that above-mentioned purpose the utility model adopts following technical scheme:
A kind of low voltage electromagnetic actuating permanent magnetism keeps driving mechanism, comprises the power conduction axis, and upper magnet yoke cover plate, column type move the closed magnetic circuit of iron core, U type outer yoke, circular ring type permanent magnet, solenoid composition, it is characterized in that:
1. connect at the centre bore and the moving iron core screw thread of column type of above-mentioned power conduction axis by the upper magnet yoke cover plate;
2. between above-mentioned column type static iron core, circular ring type permanent magnet, U type outer yoke three, use the bonding location of high-strength adhesive;
3. being furnished with skeleton at above-mentioned solenoid is enclosed within the U die cavity that places U type outer yoke on circular ring type static iron core and the column type permanent magnet, the upper magnet yoke cover plate moves the cavity that iron core is put into solenoid together with power conduction axis and column type, and upper magnet yoke plate shaft screw thread between excircle and U type outer yoke top inner periphery connects.
Plane on the upper magnet yoke cover plate of above-mentioned a kind of low voltage electromagnetic actuating permanent magnetism maintaining body is provided with the assembly technology blind hole.
The column type static iron core lower plane center of circle of above-mentioned a kind of low voltage electromagnetic actuating permanent magnetism maintaining body is provided with tapped blind hole, and the center of circle, U type outer yoke bottom is provided with through hole.
The utility model power conduction axis both can adopt non-magnet material silicon bronze or 1Cr18Ni9Ti material, also can adopt No. 45 high-abrasive materials such as steel of permeability magnetic material to manufacture, such purpose of design is to reduce cost and friction relation and the magnetic field resistance between influence power conduction axis and the upper magnet yoke cover central hole not.
The shaped design purpose of the utility model circular ring type permanent magnet is simplified structure, reduces the purchase cost of circular ring type permanent magnet, only needs a sintered NdFeB circular ring type permanent magnet both can achieve the goal.
The utility model column type static iron core is established tapped blind hole, and the circular ring type permanent magnet is provided with through hole, and the center of circle, U type outer yoke bottom is provided with port, and the three cooperates corresponding, and purpose is convenient to bolt after being to pack in the contactor or the shell that opens circuit.
Description of drawings
Fig. 1 is the axial cut-away view of a kind of low voltage electromagnetic actuating of the utility model permanent magnetism maintaining body gate-dividing state.
The closed magnetic circuit that a kind of low voltage electromagnetic actuating permanent magnetism maintaining body shown in Figure 1 is made up of power conduction axis 1, upper magnet yoke cover plate 2, the moving iron core 3 of column type, U type outer yoke 4, column type static iron core 5, circular ring type permanent magnet 6, solenoid 7.
Embodiment
The course of work of the utility model embodiment is: during electric switch-on, impose on solenoid 7 instantaneous forward currents by outer control circuit, the moving iron core 3 of column type is together with power conduction axis 1 and probe of contactor, overcome the support force that touch spring makes progress and move downward column type static iron core 5 positions, the moving iron core 3 of column type this moment is finished to close a floodgate with the complete adhesive in top and bottom of column type static iron core 5 and is realized that stable state keeps and touch spring is finished energy storage.Imposing on solenoid 7 instantaneous reverse currents by outer control circuit during electronic separating brake produces reverse electromagnetic field and causes that the permanent magnetism the suction-combining force is instantaneous to fall sharply, touch spring released energy and moved upward to terminal point by power conduction axis 1 synchronously together with the moving iron core 3 of column type and finish separating brake this moment, the lower plane adhesive of the last plane of the moving iron core 3 of column type and upper magnet yoke cover plate 2 is meanwhile finished separating brake and is realized that stable state keeps and touch spring plays upwards supporting role, so far finishes a work period.
