ELECTRICAL SWITCHGEAR WITH SYNCHRONOUS CONTROL SYSTEM AND ACTUATOR |
摘要 |
A closed loop feedback system controls electrical switchgear that moves at least one contact relative to another contact to switch power on and off in an AC electrical circuit. The control system includes a position feedback device that is operatively coupled to at least one of the two contacts to produce contact position information. A processor receives and analyzes the contact position information to control contact motion to provide AC waveform synchronized switching. The electrical switchgear may be a capacitor switch that includes a bi-stable over-toggle latching device. The latching device maintains the contact in one of an open stable position in which electrical current does not flow through the contacts or a closed stable position in which electrical current flows through the contacts.
