High voltage synchronous switch for capacitors

摘要

A contact structure for a switch that switches capacitors into multi-phase, high voltage transmission lines. There is one capacitor switch for each phase of the transmission line, and each switch has two contacts, a stationary contact and a movable contact. All of the switches begin the transition from the open to closed position at substantially the same time, and all of the movable contacts move towards their respective stationary contacts at substantially the same velocity. Each stationary contact is positioned at a predetermined distance from its movable contact when the switch is in an open position so that the time it will take for each switch is transition between the open and closed position is known. The synchronous timing of closing each switch, and therefore switching-in each capacitor into its respective high-voltage line, is achieved based on the positioning of the stationary contacts.
