Abstract: A bypass blade is pivotably connected to the first terminal pad, and movable between open and closed positions. The bypass blade is electrically connected between the first and third terminal pads when in the closed position. A first disconnect blade is pivotally connected to a second terminal pad and movable between open and closed positions. The first disconnect blade is electrically connected between the first and second terminal pads when in the closed position. A second disconnect blade is pivotally connected to a fourth terminal pad and movable between open and closed positions.

Abstract: Improved switchblade-type, air dielectric switchgear apparatus is provided which utilizes a minimum of supporting insulators and incorporates readily field-replaceable bushing assemblies so that the switchgear apparatus may be serviced in the field using only conventional tools. In preferred forms, the switchgear apparatus includes internal switch assemblies making use of substantially vertically oriented switchblades mounted for pivotal movement about an elevated, generally horizontal axis located above the corresponding stationary contacts. The replaceable bushing assemblies are advantageously mounted at a level for interconnection with the upper ends of associated switchblades, and the assemblies include a conical outermost connection and adapted to receive a line connecting elbow, together with an elongated, inwardly extending, electrically conductive intermediate portion carrying an innermost terminal. The inner terminal is designed for frictionally engaging the upper end of an associated switchblade, and for this purpose includes a pair of depending, spring-loaded contact plates. If a given bushing assembly requires replacement, it is only necessary to externally disconnect the assembly from the switch housing wall, followed by manual removal of the defective assembly. An identical replacement assembly is then inserted through the tank wall and the assembly terminal is initially positioned relative to the switchblade, this operation being facilitated by visual inspection through a window below the bushing assemblies. The replacement bushing is then attached using external connection hardware, this operation serving to properly and finally position the terminal relative to the switchblade.

Abstract: Improved blade-type, air dielectric switchgear apparatus is provided having spring loaded, fast acting, operator independent mechanism for selective opening and closing of internal switch contacts. Preferably, the operating mechanism includes a pair of opposed, pivotal, notched, scissor-like arms with a rotatable latch plate therebetween; a pair of latching pins are carried by the plate, and the latter is operably connected with a power spring assembly. A trip element is also provided which, upon rotation thereof in either a clockwise or counterclockwise direction, serves to shift a corresponding arm away from the latch plate to disengage the latching components. At this point a high velocity rotational movement is imparted to the latch plate by the spring assembly to rotate the latch plate to a second position wherein the plate and the opposed arm come into latching engagement. The trip element is provided with stops to prevent pivoting thereof to an over center condition with respect to the power spring assembly, thereby eliminating the possibility that a lineman operating the switchgear will mistakenly believe that the switchgear contacts have been separated, when in fact they have remained in engagement. The pin and notch latching arrangement is also designed to give a positive weld break function during initial stages of operation of the mechanism. The switchblade shaft is preferably pivotally supported by means of an inexpensive threaded connection which also gives a degree of axially adjustability to the shaft.
