Abstract
A magnetizing current switch particularly adaptable for use in gas insulated substations comprising a sealed housing including two spaced-apart electrical conductors and a movable contact for electrically connecting or disconnecting the electrical conductors. A rotatable drive shaft is coupled to drive means, which translate the rotation of the drive shaft to a generally straight-line motion, and the straight-line motion moves an insulating rod which is secured to the contact, thereby positioning the contact either in contact with both conductors, or spaced apart from at least one of them. The drive means includes a pair of support members and a pair of spaced-apart pivot links pivotally coupled to the support members. One of the pivot links is coupled to the drive shaft, and a link connector couples the pivot links together. The link connector can rotate within the pivot link openings provided therein, and upon pivotal movement of the pivot links, the link connector experiences both an arcuate and a rotational movement. Spaced-apart drive arms fixedly secured to the link connector cooperate with the insulating rod, and upon the arcuate and rotational movements of the link connector, the free end of the drive arm traverses a substantially straight line, thereby moving the insulating rod and the movable contact.
