The operation principle of permanent-magnet manipulating mechanism is the process of kinetic energy electric energy conversion, realized combined floodgate and the separating brake function of matched with vacuum circuit breaker by controller management and control Conversion of Energy.When the magnetic field produced after mechanism's magnet exciting coil energising is consistent with magnet intrinsic magnetic field direction, form magnetic after two magnetic field superposition to make a concerted effort, along with the continuous increase of coil drive current, the actuating force that magnetic field produces also becomes large gradually, when actuating force is greater than the separating brake confining force of circuit breaker, dynamic iron core moves to combined floodgate direction, drive the moving contact of breaker vacuum arc control device and fixed contact to close simultaneously, now permanent magnet and iron core form ferromagnetic closed-loop path, magnetic resistance is very little, the magnetic field the suction-combining force formed has been enough to the closing retention force overcoming circuit breaker, controller cuts off magnet exciting coil power supply automatically, need not coil current magnetic field and complete the snap close process of combined floodgate, finally complete the closing function of circuit breaker, when magnet exciting coil produce magnetic field and permanent magnet intrinsic magnetic field produce direction contrary time, two magnetic field strength are at a stalemate, permanent magnet and iron core form ferromagnetic closed-loop path and are broken, circuit breaker loses closing retention force, dynamic iron core returns rapidly and is positioned at open position under the effect of tripping spring power, finally completes the separating brake function of circuit breaker.
Permanent-magnet manipulating mechanism mainly adopts electric operating in electric automatization application, and when power supply or controller break down, the breaking-closing operating of supporting circuit breaker just needs to complete manually.At present, the emergency manual separating brake technology of permanent magnet mechanism is comparatively ripe, and closing by hand technology is limited by the limitation of permanent magnet mechanism structure, particularly more difficult realization in the middle of the application of Monostable permanent magnetic mechanism.
Summary of the invention
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provides a kind of compact structure to design, and possesses high-tension Vacuum switch that is electronic and manual operation function simultaneously and drives permanent magnet mechanism.
The technical solution adopted in the present invention is: take permanent magnet mechanism as electric operating main body, is operating as manual operation main body with spring energy-storage, then two main bodys by frame and machine driving composition entirety.Wherein, permanent magnet mechanism main body is open type monostable configuration, permanent magnet mechanism base through screws is installed on the centre position of frame, connector is equipped with at the top of permanent magnet mechanism static magnetic yokes, roller is equipped with in connector inside, roller be used for accepting and transmission closing by hand time fault offset, the connecting lever above circuit breaker driving shaft is installed in connector outside, and connector, roller and connecting lever three pass through pivot pin synchronization action, the inner side of frame front end is designed with gear graduation and clutch apparatus, wherein, pinion is installed on the position of axle 1 by axle sleeve, energy storage closing operating grip is installed by single direction ratchet in one end of axle, pinion upper end is meshing with gear wheel after installing non-return machine pawl, gear wheel, castle wheel, cam and connecting lever are installed and axle 2 position by coaxial bearing, the opposite side of frame fixes one end of energy-stored spring by connecting lever and spring-hanging board, the other end of spring is fixed on by hanging spring abutment and straining adjusting bolt the one end hanging spring hanging scroll, hanging spring shaft is installed on the position of axle 4 by axle sleeve, axle 1, axle 2, the associative combination of axle 4 and element thereof defines Manual spring energy storage closing assembly.Be welded above separating brake axle little cam and spacing connecting lever, is installed on axle 3 position of mechanism by axle sleeve, and separating brake axle and combined floodgate assembly are manual operation main bodys of the present invention.
Positive beneficial effect of the present invention is:
1. the present invention adds permanent magnet mechanism the closing by hand function of spring mechanism, and integrated design, had both possessed permanent magnet mechanism failure rate is low, ran advantage more reliably, also possess the strong point of closing by hand function containing spring mechanism, make the operating function of permanent magnet mechanism more complete.
2. the integrated design of spring mechanism and permanent magnet mechanism, decreases the consumption of associated materials, reduces mechanism and takes up room in the installation of circuit breaker case inside.
3. meet modular design concept, be convenient to Installation and Debugging and working service.
4. the present invention successfully solve controller lose permanent magnetic vacuum breaker that power supply or faults itself cause can not the emergency manual defect of closing a floodgate, can ensure that more high voltage permanent magnet vacuum circuit breaker can run by closing by hand during changer controller, effectively reduces feeder line fault outage rate.
