ABSTRACT:
A disconnecting switch for a high voltage electrical substation, including a plurality of articulated arms pivotally connected together to define a movable system, one end of the movable system connected to a stationary support. The switch includes a contact head connected to an opposite end of the movable system, a main conducting bar suspended from a high voltage conductor, such that the contact head is movable between the main conducting bar and the stationary support via the movable system, and a stationary arcing contact electrically connected to the main conducting bar. The contact head includes an insulating fork defined by a v-shaped splayed part for contact with and centering of the main conducting bar, and a central slot which receives the main conducting bar, a movable main contact for electrical contact with the main conducting bar during engagement in the central slot, a movable arcing contact whip including a retaining pin and an operating mechanism for controlling the movable arcing contact whip to electrically contat the stationary arcing contact, including a trip lever and a finger, the finger movable between a locked position to lock the retaining pin and an unlocked position to unlock the retaining pin, the finger being driven by the trip lever which is biased from contact with the main conducting bar.
