Abstract
The utility model relates to a permanent magnetic operating mechanism for a vacuum circuit breaker. The permanent magnetic operating mechanism comprises a magnetic conductive hoop, a movable iron core, a static iron core, a coil and a vacuum tube pull rod, wherein a magnet is arranged between the static iron core and the magnetic conductive hoop, the static iron core is arranged above the movable iron core, and the static iron core is arranged in the magnetic conductive hoop. The permanent magnetic operating mechanism is characterized in that the movable iron core and the coil are arranged on the outer side of the magnetic conductive hoop, and the coil is wound on the movable iron core. By adopting the technical scheme, the utility model provides the permanent magnetic operating mechanism for the vacuum circuit breaker, and the permanent magnetic operating mechanism is convenient to install and replace by arranging the coil on the outer side of the magnetic conductive hoop.
Description
Technical field
The utility model relates to the vacuum circuit-breaker field, particularly a kind of permanent-magnet manipulating mechanism of vacuum circuit-breaker.
Background technology
The permanent-magnet manipulating mechanism of existing vacuum circuit-breaker, magnetic conduction hoop, moving iron core, static iron core, coil have been generally comprised, the vacuum tube pull bar, tripping spring, overtravel spring, be provided with magnet between static iron core and the magnetic conduction hoop, static iron core is positioned at moving iron core top, and described tripping spring, overtravel spring all are set on the vacuum tube pull bar, described moving iron core, static iron core, coil all are arranged in the magnetic conduction hoop, and the coil winding is on moving iron core.During combined floodgate, coil electricity, the effect that moving iron core is subject to electromagnetic force moves upward; When separating brake, coil leads to reverse current, and electromagnetic force disappears, and under tripping spring, overtravel spring force action, moving iron core moves downward.
But, the permanent-magnet manipulating mechanism of the vacuum circuit-breaker of this structure because described coil is arranged in the magnetic conduction hoop, its install, when changing, need to be with dismountings such as magnetic conduction hoop, moving iron cores, like this so that its installation, change inconvenience.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of permanent-magnet manipulating mechanism of vacuum circuit-breaker, by coil being arranged on the magnetic conduction hoop outside, can conveniently install like this, change.
The technical solution of the utility model: a kind of permanent-magnet manipulating mechanism of vacuum circuit-breaker, include magnetic conduction hoop, moving iron core, static iron core, coil, the vacuum tube pull bar, be provided with magnet between static iron core and the magnetic conduction hoop, static iron core is positioned at moving iron core top, described static iron core is arranged in the magnetic conduction hoop, it is characterized in that: described moving iron core, coil all place the magnetic conduction hoop outside, and described coil winding is on moving iron core.
Adopt technique scheme, by coil being arranged on the magnetic conduction hoop outside, can conveniently install like this, change.
Further setting of the present utility model: described magnetic conduction hoop top is provided with not magnetic conduction pressing plate, and described static iron core is fixedly connected with through screw with pressing plate.
Adopt above-mentioned further setting, the static iron core locate mode of this structure, installation, convenient disassembly, simple in structure, cost is low.
Again further setting of the present utility model: described magnetic conduction hoop is extended with annular retaining ring to the inside, and described magnet lower surface and annular retaining ring conflict form the location to magnet.
Adopt above-mentioned more further setting, this magnet locate mode, easy to process, simple in structure.
