The two sides of the outer magnetic roll form a mounting table board, the mounting table board is provided with mounting holes, the front cover is provided with a pair of mounting racks in parallel in an integral manner, a main connecting plate is arranged between the mounting racks, the center of the main connecting plate is hinged to the mounting racks, and one end of the main connecting plate is hinged to the top of the driving rod. According to the utility model, the mounting table board is added to the permanent magnetic mechanism, the front end of the driving rod is added with the main connecting plate and an opening cam, and therefore the permanent magnetic mechanism is relatively simple to install, the permanent magnetic mechanism can be directly installed with no need for changing a vacuum circuit breaker, and after the permanent magnetic mechanism is installed, an adaptive main connecting plate and an adaptive opening cam do not need to be installed, a plurality of mounting steps are omitted, the permanent magnetic mechanism is relatively simple to install, the assembling cost is saved, and the permanent magnetic mechanism is relatively easy to use.
Description
Technical field
The utility model relates to a kind of permanent magnet mechanism, especially a kind of monostable unicoil permanent magnetic actuator for high-pressure vacuum contactor.
Background technology
The operating mechanism of traditional high-pressure vacuum contactor for high-tension circuit has spring operating mechanism and electromagnetic operating mechanism.Spring operating mechanism is comprised of spring energy-storage, combined floodgate, maintenance combined floodgate and the several parts of separating brake, and advantage is not need powerful power supply, and shortcoming is complex structure, and manufacturing process is complicated, and cost is high, and reliability is difficult to ensure card; Electromagnetic operating mechanism structure is simpler, but structure is heavy, and closing coil consumed power is very large.More than having used for reference, on the basis of the pluses and minuses of two kinds of operating mechanisms, permanent magnet mechanism has carried out improving design.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provides a kind of simple in structure, the permanent magnet mechanism of dependable performance.
For achieving the above object, the utility model adopts a kind of permanent magnet mechanism, comprise drive rod, outer magnetic rolls, permanent magnet, front shroud, back shroud, coil rack, moving iron core, coil, static iron core, moving iron core sleeve is in drive rod rear end, moving iron core is outside equipped with static iron core, static iron core is outside equipped with permanent magnet, coil rack is arranged on outside drive rod, coil is on coil rack, outer magnetic is pricked and is wrapped in outside coil and permanent magnet, front shroud is arranged on the front end of coil rack, back shroud is arranged on the rear end of moving iron core, described outer magnetic is pricked both sides and is integrally formed installation table top, install on table top and be provided with installing hole, on described front shroud, be integrally formed a pair of installing rack being parallel to each other, between installing rack, be provided with main connecting plate, main connecting plate center hinge is connected on installing rack, main connecting plate one end and drive rod top are hinged.
The utility model is further set to described installing rack top and is hinged with manual brake separating axle, on the manual brake separating axle between installing rack, is fixedly installed a minute brake cam, and a minute brake cam withstands on drive rod front end.
The utility model is further provided with cushion block between the static iron core in, outer magnetic bundle outer at moving iron core and separating brake cover plate.
The beneficial effects of the utility model are that permanent magnet mechanism adopts new construction, and reliability is high, reaches perfect cooperation with the body of primary cut-out, and then improves the performance of primary cut-out, and parts are few, and power consumption is few; And on permanent magnet mechanism, increased installation table top, front end installs main connecting plate additional and a minute brake cam all makes the installation of permanent magnet mechanism easier, not needing to change vacuum circuit-breaker just can directly install, and do not need to install again adaptive main connecting plate and minute brake cam after installing permanent magnet mechanism, a plurality of installation steps have been saved, install simplyr, saved assembly cost, ease for use is higher.
