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 unloc…
