Abstract
The utility model provides a monocoil and monostability permanent magnetic operation mechanism. The utility model is characterized in that a non magnetic conductive covering plate is fixed at the upper end of a cup shaped static iron core. A connection rod is penetrated between the middle of an armature. A coil is fixed at the inner surface layer of the static iron core. The upper end of a permanent magnetic body is connected with a magnetic circuit guide ring; the lower end thereof is connected with the coil. The outer surface of the permanent magnetic body is connected with the inner surface of the static iron core. One end of a switch off spring is connected with the connection rod, and the other end thereof is fixed on an outer shell. The utility model provides the advantages of few component quantities, stable characteristics, and maintenance free during long term operation. Therefore, the utility model is in particular suitable to match with vacuum switch.
Description
Technical field:
The utility model relates to a kind of operating mechanism of High-Voltage Electrical Appliances vacuum switch, and particularly a kind of is the supporting unicoil Monostable permanent magnetic mechanism of vacuum switch.
Background technology:
At present, the vacuum switch that China High-Voltage Electrical Appliances use has obtained to use widely because of himself advantage, but all has a lot of shortcomings for its supporting spring operating mechanism, and is many such as number of spare parts, the characteristic instability, and long-term reliability is not high.
Summary of the invention:
The purpose of this utility model is the deficiency at above-mentioned proposition, provides a kind of vacuum switch supporting unicoil Monostable permanent magnetism operating mechanism.It is few to have number of spare parts, stability of characteristics, and long-time running is non-maintaining, is particularly suitable for vacuum switch supporting.
The purpose of this utility model is achieved in that and comprises coil, static iron core, moving iron core, it is characterized in that, at the fixing non-magnetic conduction cover plate in the upper end of cup-shaped static iron core, connecting rod interts in the middle of moving iron core, and coil stationary is in the interior surface layers of static iron core, and the upper end of permanent magnet links to each other with the magnetic circuit guide ring, the lower end links to each other with coil, its outer surface links to each other with the static iron core inner surface, and an end of tripping spring links to each other with connecting rod, and the other end is fixed on the shell.
The utility model has the advantages that it is few to have number of spare parts, stability of characteristics, long-time running is non-maintaining, is particularly suitable for vacuum switch supporting.
Description of drawings:
Accompanying drawing is a structure chart of the present utility model
Embodiment;
By accompanying drawing as can be known, moving iron core 7 is shorter than static iron core 5, and the external diameter of moving iron core is less than the internal diameter of static iron core, at the fixing non-magnetic conduction cover plate 2 in the upper end of cup-shaped static iron core 5, connecting rod 8 interts in the middle of moving iron core 7, moving iron core can be done two-way linear along axis and move in the enclosure space of static iron core and non-magnetic conduction cover plate formation, coil 6 is fixed on the interior surface layers of static iron core 5, and the external diameter of coil is identical with the external diameter of permanent magnet.Permanent magnet 4 is a neodymium iron boron cylindraceous, outer surface is a magnetic pole, inner surface is another magnetic pole, the external diameter of permanent magnet is identical with the internal diameter of static iron core, its upper end links to each other with magnetic circuit guide ring 3, and the lower end links to each other with coil 6, and its outer surface links to each other with static iron core 5 inner surfaces, one end of tripping spring 1 links to each other with connecting rod 8, and the other end is fixed on the vacuum switch shell.Its operation principle is that the making process coil leads to the big electric current of forward, moves iron core and moves to closing position by the separating brake position, permanent magnet constitutes magnetic loop by moving iron core, static iron core, suction between moving iron core and static iron core, produces suction, as long as can remain on closing position greater than the load counter-force.The logical reverse little electric current of coil weakens combined floodgate magnetic loop magnetic flux during separating brake, makes under the effect of suction less than the load counter-force and moves to the separating brake position.
