The invention relates to contact permanent magnetism pulse electromotion operation structure. Static iron core is set on the basal and static iron core matches to permanent coil. Moving iron core is set on the static iron core. The feature is that moving iron core is made up of magnetic conductor, permanent magnetic steel, and clip plate. The permanent magnetic steel is set between magnetic conductors. And clip plates are set at two sides of magnetic conductor, permanent magnetic steel. Grooves are set corresponding to the static iron core attracting surface. The invention needs no maintaining current, low power consumption, and could decrease producing and using cost.
Description
Technical field
The invention belongs to technical field of electric appliances, be specially contactor permanent magnet pulse electric operating mechanism.
Background technology
Contactor is a kind of automatic control apparatus, and it can be used for being switched on or switched off at a distance continually jumbo AC and DC load circuit.Contactor can be divided into two kinds of direct current and A.C. contactors by the kind difference of main contacts by electric current, and present control circuit adopts A.C. contactor more.The operating mechanism of existing contactor is electromagnetic type, and electromagnet is big, and confining force is little, need during work with keeping electric current, both consuming electric power made coil heating again, will burn out coil during low pressure, can produce noise simultaneously, in case supply voltage disappears or significantly reduces, moving iron core will not be released because there being enough electromagnetic attractions, because its just-off speed is slow, the current interruption ability, thus contact useful life shortened.Improve the arc extinguishing ability if improve the spring counter-force, just must improve and keep electric current, certainly will improve energy consumption and raw-material consumption, increased production and operating cost greatly.In addition, the magnetic density unshakable in one's determination of contactor can not be obtained too high, generally is up to 7600 Gausses, so that the pressure of contact pressure spring can not be obtained is too big, so contact resistance is all bigger, influences the use capacity of contactor.And, avoid coil to burn out in order to reduce coil temperature rise, and electromagnetic wire is all with the copper envelope curve, and price height and capacity are little.Once designed the technical scheme of permanent magnet pulse contactor before the applicant, and applied for patent, number of patent application is: 200410017488.5, and the general structure of its motor-operating mechanism has solved problems of the prior art basically.As long as just can realize the inherent function of contactor by about 0.2 second pulse current, do not need to consume and keep electric current, self energy consumption is saved more than 99%, solenoid does not generate heat, and can not burn out, and not cause noise pollution because of energising, and the just-off speed of contact is fast, the arc extinguishing ability is strong, and not fragile contact has improved contact useful life.But also there are certain defective in concrete modular construction and annexation in the above-mentioned patent application, such as: the structural design of moving iron core, static iron core is unreasonable, can not realize best electromagnetic adhesive effect, and actual production processing is difficulty relatively, the cost height can't satisfy the best result of use of contactor.
Summary of the invention
Purpose of the present invention just is to overcome the defective of prior art, design provides a kind of technical scheme of contactor permanent magnet pulse electric operating mechanism, electric current and confining force are big, capacity is big thereby need not keep when making contactor work, reduce the production and the operating cost of contactor simultaneously, improve the useful life of contactor.
To achieve these goals, the present invention adopts following technical scheme:
Contactor permanent magnet pulse electric operating mechanism, connect on the base static iron core is set, static iron core cooperates with solenoid, be equipped with moving iron core corresponding to the static iron core top, it is characterized in that described moving iron core is made of magnetic conductor, permanent magnetic steel, clamping plate, permanent magnetic steel is arranged between the magnetic conductor, and magnetic conductor, the connection of permanent magnetic steel both sides are provided with clamping plate, and corresponding static iron core adhesive face is provided with groove.
Described contactor permanent magnet pulse electric operating mechanism is characterized in that permanent magnetic steel is symmetricly set in the centre of magnetic conductor, and permanent magnetic steel is provided with mounting up and down respectively, and corresponding static iron core is set to the U-shaped structure.
Described contactor permanent magnet pulse electric operating mechanism is characterized in that permanent magnetic steel is arranged at the both sides of magnetic conductor symmetry, and permanent magnetic steel is provided with mounting up and down respectively, and corresponding static iron core is set to W shape structure.
Described contactor permanent magnet pulse electric operating mechanism is characterized in that solenoid is unicoil, twin coil or tapped coil.
Described contactor permanent magnet pulse electric operating mechanism is characterized in that the static iron core both sides are provided with shock-absorbing sleeve by bolster respectively.
Described contactor permanent magnet pulse electric operating mechanism is characterized in that the static iron core below is provided with vibration damping sheet.
Described contactor permanent magnet pulse electric operating mechanism is characterized in that solenoid adopts pure iron silk enamelled wire.
Above-mentioned contactor permanent magnet pulse electric operating mechanism, except not needing to keep electric current, outside the advantages such as it is low to consume energy, owing to further improved the structural design of moving iron core and static iron core, the confining force when further having increased moving iron core and static iron core adhesive and the use capacity of contactor can be applied on existing various AC and DC contactor and the vacuum-tube switch preferably.And processing, install and use conveniently, further reduced production and use cost, prolonged the useful life of product.
