Latest Patents

Among his latest inventions, the "Method of Assembling Rotary Puffer Switch" stands out. This innovative design features a cylindrical shell filled with an insulating gas like sulfur hexafluoride. It incorporates multiple spaced parallel plates to define compression chambers for each phase of an electrical power circuit being switched. Each chamber contains contact sets that are exposed to arcing as they open or close. Essential to this design is a movable contact that includes an impeller blade, which rotates to compress the insulating gas before directing it onto the contacts to prevent arcing. The assembly process is cost-effective, requiring thermosetting plastics for hot components, while most parts are made from lower-cost thermoplastics.

Another significant patent is the "Switch Operating Mechanism," where an operator plate supports a finely engineered actuator mechanism. The operator shaft transmits torque from an operating handle, compressing a torsion spring for temporary energy storage. This spring plays a key role in mechanically coupling the generated torque to a rotor tube to operate the switch contacts. The design includes a spring guide to ensure optimal energy storage and prevent spring deformation during operation, enhancing the durability and reliability of the switch.
