Abstract
The utility model relates to the high and low voltage switch accessories, especially relates to the actuator and belongs to the electric appliance technology field. The utility model discloses a full-enclosed permanent magnetic actuator possessing an auxiliary electromagnetic loop. An annular auxiliary magnetic yoke, which is arranged on an outer magnet yoke, is an important component of the auxiliary electromagnetic loop and is also a key part in electromagnetic shielding and dustproof sealing assemblies. The actuator possesses low power consumption and a small size. An amount of the permanent magnet is less. By using the actuator, electromagnetic interference can be effectively shielded and outside dust can be prevented from entering into an actuator cavity so that cleanness of an electromagnetic and permanent magnet suction working surface is ensured.
Description
Technical field
The utility model relates to high and low pressure vaccum electric apparatus switch fitting, particularly operating mechanism, belongs to technical field of electric appliances.
Background technology
In recent years, permanent-magnet manipulating mechanism is highly reliable with it, long-life, the advantage such as easy to control cause in the industry common concern and developed rapidly, although the assembly of permanent-magnet manipulating mechanism seldom, can consist of multiple magnetic structure form.The permanent-magnet manipulating mechanism of multi-form magnetic structure is in the process of carrying out the conversion of high and low pressure vacuum switch state, all have very big-difference with static mechanical characteristics, dynamic characteristics and the kinetic characteristic mechanical, electrical, that magnetic intercouples of time correlation, it directly affects the matching properties of operating mechanism and vacuum switch.The utility model people once disclosed a kind of permanent-magnet manipulating mechanism with auxiliary electromagnetic circuit at ZL201120314425.1 and application number 201110249411.0, but belonged to type semienclosed.
The utility model content
The purpose of this utility model is, provides a kind of Totally-enclosed-type to have the permanent-magnet manipulating mechanism of auxiliary electromagnetic circuit.
The purpose of this utility model is achieved in that in outer yoke ring-type being set assists yoke, and it is the important component part of auxiliary electromagnetic circuit, again the double vital part of doing in electromagnetic shielding and the dust seal assembly.
In the utility model technical solution, a kind of permanent-magnet manipulating mechanism with auxiliary electromagnetic circuit, provide the permanent-magnetic field source by permanent magnet, produce transient electromagnetic field and the forward and reverse stack of permanent magnetic field by external circuit control magnet exciting coil, drive the moving iron core motion state conversion of finishing the work; It is characterized in that: moving iron core is closed in the cavity that consists of after equipped by outer yoke and upper end cover.Wherein, described outer yoke is the ladder barrel shape, and adopt high permeability material to manufacture, its top is provided with the auxiliary yoke of ring-type and radially corresponding with the periphery of moving iron core, its toroidal adhesive interface is axially corresponding with the second adhesive face of moving iron core, described upper end cover is manufactured by non-magnet material, and the top of described moving iron core is provided with steam vent.
When this mechanism is carrying out in the closing operation transient process, moving iron core consists of the auxiliary electromagnetic circuit of this mechanism by air gap Lg and the auxiliary yoke Dynamic Coupling of ring-type, after closing operation finishes, and magnetic field diminishes, permanent magnetic field main flux loop gapless is closed, and auxiliary electromagnetic circuit is bypassed.
Employing the utility model proposes and be configured in the permanent-magnet manipulating mechanism on the high and low pressure switch, and closing operation has improved the distribution of suction electromagnetic field, and the permanent magnet consumption is few, and volume is little, and is low in energy consumption, and can effectively guarantee the electromagnetism cleaning of adhesive working face.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is in the cutaway view of gate-dividing state for this mechanism.
Fig. 2 is in the cutaway view of "on" position for this mechanism.
Embodiment
Below in conjunction with details and the operation principle of accompanying drawing detailed description according to the mechanism that the utility model proposes.
Contrast Fig. 1 can find out, outer yoke 2 be shaped as ladder barrel, moving iron core 5 is sealed in the cavitys 12 that outer yoke 2 and upper end cover 6 consist of after equipped.The top of moving iron core 5 is provided with steam vent 8, the periphery 7 of moving iron core 5 is provided with air gap Lg and corresponding with the inner headed face 10 of the auxiliary yoke 4 of ring-type, toroidal adhesive interface 11 is axially corresponding with the second adhesive face 9 of moving iron core 5, as the part in electromagnetism, permanent magnetism main flux loop.
Contrasting Fig. 2 can find out, when this mechanism was in "on" position, electromagnetic field disappeared, moving iron core 5 closures, and terminal location keeps relying on the permanent magnetism the suction-combining force, and auxiliary electromagnetic circuit is bypassed.
This mechanism is configured on the high and low pressure switch, its operation principle is: closing operation, magnet exciting coil 3 produces the electromagnetic field with the permanent magnetic field Downward addition under external circuit control, auxiliary electromagnetic circuit participates in adhesive work, and the moving iron core 5 of driving leaves the separating brake terminal location and moves downward the energy storage of finishing switch contact stage clip and disjunction spring.Because the setting of auxiliary electromagnetic circuit has improved the distribution of suction electromagnetic field, has shortened operate time, has reduced power consumption.After moving iron core 5 arrives the combined floodgate terminal location, rely on permanent magnetism the suction-combining force stable state to keep, at this moment, auxiliary electromagnetic circuit is bypassed after having finished its function; Sub-switching operation, magnet exciting coil 3 produce under external circuit control and the reverse electromagnetic field that superposes of permanent magnetic field, make confining force be down to critical value, and common driving of tripping spring and contact stage clip moved iron core 5 arrival separating brake terminal locations, and dependence buffering lubricating cup keeps.
