Abstract
The utility model relates to a double-purpose subminiature permanent magnetism mechanism of a vacuum contactor and a vacuum circuit breaker, which comprises a movable iron core, a fixed iron core, a closing and separating coil and a permanent magnet, wherein the fixed iron core is fixed on an aluminum plate by a bolt, the permanent magnet is connected in a magnetic conduction sleeve which is fixed on the aluminum plate by a fixing bolt, the permanent magnet is in contact with the fixed iron core, the losing and separating coil is buckled in the magnetic conduction sleeve by a clamp spring, and the movable iron core is riveted with a movable plate which is arranged above the magnetic conduction sleeve. The utility model has the advantages of simple structure, small volume and convenient and effective fixation.
Description
Technical field
The utility model relates to vacuum contactor and vacuum circuit-breaker technical field, refers in particular to a kind of vacuum contactor and vacuum circuit-breaker double-purpose permanent magnet mechanism.
Technical background
At present, permanent magnet mechanism is mainly used in high-pressure vacuum breaker, as CDY, VSM etc.Because reasons in structure, mechanism is bulky, can't accomplish miniaturization, so their usage space is restricted, and can not be used for low-voltage vacuum contactor and vacuum circuit-breaker.And existing permanent magnet mechanism fixed form adopts is screw thread and static iron core locking method on the coil rack, epoxy resin fixation etc., and fixing means is not very reasonable.
The utility model content
The purpose of this utility model is to provide a kind of vacuum contactor and vacuum circuit-breaker double-purpose microminiature permanent magnet mechanism, and it is simple in structure, and volume is little, convenient fixing, effective.
For achieving the above object, the solution that the utility model is taked is: a kind of vacuum contactor and vacuum circuit-breaker double-purpose microminiature permanent magnet mechanism, comprise moving iron core, static iron core, on/off switch coil, permanent magnet, static iron core is by being bolted on the aluminium sheet, and permanent magnet is connected in the flux sleeve, and flux sleeve is fixed on the aluminium sheet by set bolt, permanent magnet contacts with static iron core, the on/off switch coil is latched in the flux sleeve by interior jump ring, moving iron core and portable plate riveted joint, and portable plate is in the flux sleeve top.
The utility model is compared with the existing permanent magnet mechanism of equal confining force, and volume is little more than 50%, and it is simple in structure, can satisfy various vacuum contactors and the aspect requirement of vacuum circuit-breaker output torque.Jump ring locking method in the fixed form of on/off switch coil adopts, what adopt than existing permanent magnet mechanism fixed form is that methods such as screw thread and static iron core locking method on the coil rack, epoxy resin fixation are convenient and effective.
