Abstract
A switch automation system which activates poletop power line switches in response to signals received from a remote location. An actuator piston and cylinder assembly is mounted to a power pole in alignment with existing actuator linkage. The piston and cylinder actuator assembly is translatable in response to pressurized fluid delivered through fluid lines to the cylinder. A control unit also mounted to the power pole, and in operative association with the piston and cylinder actuator assembly, houses a source of pressurized fluid. Manual operation of the poletop switches is retained by an existing operating lever. Adjustment linkage is provided for proper positioning of the actuator assembly with the existing actuator linkage. Operating signals received by the control unit result in activation of solenoids to deliver the pressurized fluid to the cylinder. Simplicity of design and linear alignment with the existing actuator linkage allow for easy installation and operation.
