Abstract
A drive system for a single-phase switch includes: a first latch device; a trip latch device coupled to the first latch device; and a crank device coupled to the trip latch device and configured to control a switch actuation device to perform an open operation or a close operation in a switch. The trip latch device moves laterally during the open operation and during the close operation.
Claims22
A drive system for a single-phase switch, the drive system comprising:
- a first latch device;
- a trip latch device coupled to the first latch device;
- and
- a crank device coupled to the trip latch device and configured to control a switch actuation device to move a moveable electrical contact of a switch relative to a fixed electrical contact of the switch, wherein the trip latch device moves laterally during an ordinary open operation of the switch and during an ordinary close operation of the switch, and the trip latch device moves during a trip operation of the switch.

An electrical apparatus comprising:
- a switching system comprising:
- a first electrical contact;
- a second electrical contact;
- and
- a switch actuation device controllable to move the second electrical contact relative to the first electrical contact;
- and
- a drive system comprising:
- a first latch device;
- a trip latch device coupled to the first latch device;
- and
- a crank device coupled to the trip latch device and configured to control the switch actuation device to move the second electrical contact relative to the first electrical contact, wherein the trip latch device moves laterally without substantially changing shape during an ordinary open operation of the switching system and during an ordinary close operation of the switching system.

A system comprising:
- a plurality of single-phase switches, each switch configured to be coupled to one phase of a multi-phase alternating current (AC) power system and each switch comprising:
- a first electrical contact;
- a second electrical contact;
- and
- a switch actuation device controllable to move the second electrical contact relative to the first electrical contact;
- and
- a plurality of drive systems, each drive system comprising:
- a first latch device;
- a trip latch device coupled to the first latch device;
- and
- a crank device coupled to the trip latch device and configured to control the switch actuation device of one of the single-phase switches to move the second electrical contact relative to the first electrical contact of the one of the single-phase switches, wherein the trip latch device moves laterally without substantially changing shape during an ordinary open operation and during an ordinary close operation.
