VACUUM CIRCUIT BREAKER USING PERMANENT MAGNETIC ACTUATOR

摘要

The present invention relates to a vacuum circuit breaker using a permanent magnet actuator, reduces the number of components greatly downsizing and possibly, there is an effect that it is possible to improve the connection by simplifying the structure, operation reliability and assemblability. ; and a plurality of iron cores and the mover, wherein the direction is movably installed in the space portion of the iron core in the vacuum circuit breaker of the present invention is a laminate having a certain space therein, for this purpose, the is coupled to the lower end of the mover, and the direction of the drive rod and movable in a predetermined distance, the plurality of the movable permanent magnet and bonded to the outer periphery party, a number of times wound on top of the permanent magnet trip as the outer periphery of the mover coil and a permanent magnet type actuator having a plurality of times In a coil wound on an outer peripheral lower portion of the permanent magnet of the mover; It is provided at the lower load drive of the permanent magnet type actuators, a block for transmitting the upper and lower direction of the power of the drive rod; The first lever can rotate according to the phase, and direction of the power block with one end is coupled to the block; Opening and closing shaft is coupled with the other end of the first lever can be rotated in the same direction as the rotation direction of the first lever; Coupled to the opening and closing shaft, a second lever rotatable in the same direction in accordance with the opening and closing shaft rotation direction; On with the rotation of the second lever, which is off the vacuum block portion; And said vacuum block portion and a second lever is provided between the push rod for transmitting the rotational force of the second lever to the power of the upper and lower direction in the vacuum block portion; and a
