Abstract
Phase reversal switch apparatus for a three-phase high-current isolated phase bus circuit includes a non-reversing phase switch, and two groups of two reversing phase switches. The apparatus also includes a phase reversal mechanism having a rotatable operating shaft with a drive lever, a non-reversing lever, and two reversing levers coupled thereto. Locking and drive couplings are selectively engaged with the levers and operated by a shift actuator and a switch actuator to selectively operate the non-reversing switch and the first and second reversing switches to effect a phase sequence reversing operation in a secure and efficient manner.
