HIGH VOLTAGE DISCONNECT SWITCH WITH SWITCH INTERRUPTER HAVING AN ACTUATING ARM ACTUATED BY AN ARC HORN WITH A SPRING CATCH
20230223220 · 2023-07-13 · ·

A high voltage air disconnect switch having an electrical load interrupter unit responsive to the opening of the high voltage air break disconnect switch. The electrical load interrupter unit including an actuating arm is contacted, during the opening of the switch, by a moving arc horn attached to and in electrical circuit with a switch blade of the high voltage air disconnect switch. The moving arc horn has operatively attached a spring catch which engages the actuating arm with a physical holding force applied to an electric contact point between the actuating arm and the moving arc horn to firmly capture the interrupter actuating arm against the moving arc horn during opening of the switch to prevent any arc burning damage due to arcing between the actuating arm and the moving arc horn as the switch opens.

System and method for operating an electrical switch

A switch including a first electrical terminal, the first electrical terminal including a blade pivotable between an open position and a closed position, and a rod extending from the first electrical terminal parallel to the blade. The switch further includes a second electrical terminal configured to receive the blade when in the closed position, the second electrical terminal including a vacuum interrupter, wherein the vacuum interrupter engages the rod when in the closed position. Rotating the first electrical terminal in a first direction causes the blade to disengage from the second electrical terminal at a first point, and further rotating the first electrical terminal in the first direction causes the rod to disengage from the vacuum interrupter at a second point.

High voltage switch with condensation preventing bearing assembly and method therefor
11515103 · 2022-11-29 · ·

A high voltage electric disconnect switch having a rotatable switch blade in operative arrangement with a rotatable high voltage electrical insulator. A rotating bearing assembly in operative supporting arrangement with a rotatable shaft. The bearing assembly containing corrodible ball bearing assemblies including associated corrodible ball bearing races. The rotatable insulator is operatively mounted to the rotatable shaft. The rotatable shaft has a lower rotatable shaft portion contacting the corrodible ball bearing assemblies housed within a sealed housing of the bearing assembly. An air permeable hydrophobic membrane mounted in a membrane assembly is mounted in an aperture of the housing to eliminate condensing humidity within the housing, thereby preventing corrosion of the corrodible ball bearings and races, freezing water, and lubrication degradation by keeping the surfaces dry to prevent switch failure.

HIGH VOLTAGE CENTER BREAK DISCONNECT SWITCH WITH TOGGLE DRIVE LOCKING MECHANISM
20230131774 · 2023-04-27 · ·

A high voltage center break disconnect switch with two rotatable switch blades each operatively attached to a respective rotatable insulator for opening and closing the switch. A toggle locking drive assembly including a two-sided lever having three pivot points colinearly aligned thereon and two drive links each connected at one end thereof to one of the three pivot points. The two-sided lever connects at the third pivot point to a perpendicularly attached rotating shaft operatively connected to a drive pipe for opening and closing the switch. The drive links are each connected at the other end to a pivot point of a respective one of two levers each operatively mounted to one of the rotatable insulators. When the switch is in the closed position the five pivot points of the locking toggle drive assembly are aligned colinearly in a toggle lock position preventing the switch from unintended opening.
