Abstract (en)

The self-isolating three-phase interruptor comprises three insulating (7A,7B,7C) bars, each containing a vacuum chamber. The bars are solidly attached to a beam (4) which is able to pivot inside a chassis. The vacuum chambers are moved by an intermediate control shaft (10) associated with an operating mechanism. The beam is associated with an element (30) which causes a rapid rotation under spring action passing through a dead point. This operating element is controlled at the same time or immediately after the operation of the control shaft (10). The control shaft may have a pull-push action, with the operating mechanism being an electromagnet, or alternatively may have a rotary action, also produced by an electromagnet.
