Abstract
An electronic sectionalizer for a branch line of a high voltage power distribution system has a resettable actuator for unlatching a trunnion member and release of a sectionalizer tube toward a disabled or drop-out orientation. The actuator includes an elongated, spring-loaded plunger normally held by a latch in loaded position, and a solenoid or the like is provided to shift the latch and enable movement of the plunger toward a released position for simultaneous swinging movement of the trunnion member. In certain forms of the invention, the plunger is directly engageable with a wall of the trunnion member, while in other embodiments of the invention mechanical advantage is provided by use of an elongated lever which is disposed in the path of the plunger and which bears against the trunnion member for initiating rotational movement of the latter.
