The air gap changing magnetic circuit double-coil permanent magnetism operating mechanism comprises an upper magnetic yoke, an outer magnetic yoke, a closing coil, a permanent magnet, an inner magnetic yoke, a moving iron core, a carrier rod, a resetting spring, an opening coil and a lower magnetic yoke. The air gap changing magnetic circuit double-coil permanent magnetism operating mechanism adopts the structures that the double coils are distributed vertically in different cavities and the air gap changing magnetic circuit is formed along the magnetic flux direction of the magnetic circuit, therefore, not only the short circuit malfunction of the coils can be avoided, the service performance of the product is improved, but also the starting current of the operating mechanism can be reduced, the capacity of the control equipment can be lowered and the electric energy consumption can be saved.
Description
Technical field
The utility model relates to a kind of change air-gap magnetic circuit twin coil permanent-magnet manipulating mechanism that the electric power system high and low voltage switch is used.
Background technology
The permanent-magnet manipulating mechanism that present high and low voltage switch is used mostly adopts single coil structure, though solve two coils chamber mutual inductance problem altogether, avoid producing switching overvoltage, coil itself and other related control device are produced interference and harm, but when carrying out the on/off switch operation, be prone to the short circuit accident that positive-negative power bumps against in the coil, reduced the reliability that product uses.The total capacity of installed generator of current China has followed the U.S. closely and has occupied the second in the world, but electric energy is still in short supply relatively, and the sustainable development inevitable requirement of China's economic is energy-conservation; On June 24th, 2007, the Standing Committee of the National People's Congress approved " Energy Conservation Law of the People's Republic of China " revised draft, clearly was fundamental state policy with energy savings; Energy-conservation strategic position in China's socio-economic development that the Seventeenth National Congress of the Communist Party of China of holding in October, 2007 is further clear and definite relies on innovation and technological progress, and new technology, the new product of actively promoting saves energy are imperative.
Summary of the invention
Be prone to short circuit accident problem that positive-negative power bumps against and the purpose that reaches the exploitation energy-conserving product in above-mentioned because single two coil configuration coil for solving, the utility model provides a kind of change air-gap magnetic circuit twin coil permanent-magnet manipulating mechanism, this change air-gap magnetic circuit twin coil permanent-magnet manipulating mechanism adopts twin coil to divide chamber arrangement and form along the magnetic circuit flow direction and to become air-gap magnetic circuit up and down, not only avoid coil short circuit accident to occur, improve the reliability that product uses, and can reduce the starting current of operating mechanism, reduce the control appliance capacity, saves energy consumption.
The technical scheme that its technical problem that solves the utility model adopts is: closing coil and switching winding lay respectively at the both sides of inner yoke, form twin coil and divide chamber arrangement up and down, and two coils work independently, and do not disturb mutually.The utility model utilization is moved iron core in attracting process in addition, and the air-gap between the inner yoke forms the change air-gap magnetic circuit by little increase along the magnetic circuit flow direction.Like this permanent-magnet manipulating mechanism in adhesive moment the air-gap minimum along the magnetic circuit flow direction, the suction maximum of generation, starting current drops to minimum, arrives behind the closing position permanent-magnet manipulating mechanism along the air-gap maximum of magnetic circuit flow direction, the confining force maximum of generation.
The utility model comprises upper magnet yoke, outer yoke, closing coil, permanent magnet, inner yoke, moving iron core, push rod, back-moving spring, switching winding and lower yoke.It is characterized in that: upper magnet yoke and lower yoke are fastened on the outer yoke respectively; The inner yoke of permanent magnet, outer yoke are located, and are integral with inner yoke, outer yoke splicing; Push rod is fastened on the moving iron core of side band groove, runs through upper magnet yoke and lower yoke; There is a back-moving spring to be clipped between upper magnet yoke and the moving iron core on the push rod; Closing coil, switching winding place respectively in two chambeies of inner yoke upper and lower.Its feature also is: moving iron core is in attracting process, and the air-gap between the inner yoke forms the change air-gap magnetic circuit by little increase along the magnetic circuit flow direction; The top of upper magnet yoke has a step, and its width is suitable with the lower yoke bottom width; The lower yoke bottom has groove, and groove can be an annular distribution, also can be spot distribution.
During work, when closing coil moment passes to forward dc or direct impulse, the magnetic flux of electromagnetic field and the equidirectional stack of the magnetic flux of permanent magnetic field, the suction that is produced makes iron core overcome load force and moves upward, to the adhesive face up and down of moving iron core respectively with the adhesive face adhesive of upper magnet yoke, inner yoke.At this moment, upper magnet yoke, moving iron core, inner yoke, permanent magnet and outer yoke constitute closed magnetic circuit, and the magnetic flux of permanent magnetic field produces powerful confining force greater than load force by the adhesive face up and down of moving iron core, and moving iron core remains on the stable state of adhesive.When switching winding moment passes to reverse direct current or reverse impulse, the magnetic flux of electromagnetic field and the stack of the flux-reversal of permanent magnetic field, the magnetic flux by moving iron core falls sharply, and the confining force on the moving iron core adhesive face is lower than load force, and moving iron core moves downward the stable state of separating.
