Abstract
A system includes: a base; an actuator mounted to the base, the actuator including an output configured to move along a linear path relative to the base; a driving apparatus coupled to the output; and a crank apparatus including at least one crank device, the at least one crank device including: a fixed pivot point attached to the base, a moveable pivot point attached to the driving apparatus, and a connection point attached to a switch operating device. The at least one crank device rotates about the fixed pivot and the moveable pivot moves the driving apparatus relative to the base in response to the output moving along the linear path to control the switch operating device to perform one of an open operation and a close operation in a switch.
Claims18
A system comprising:
- a base;
- an actuator mounted to the base, the actuator comprising an output configured to move along a linear path relative to the base;
- a driving apparatus coupled to the output;
- and
- a crank apparatus comprising at least one crank device, the at least one crank device comprising:
- a fixed pivot point attached to the base, a moveable pivot point attached to the driving apparatus, and a connection point attached to a switch operating device, wherein the at least one crank device rotates about the fixed pivot and the moveable pivot moves the driving apparatus relative to the base in response to the output moving along the linear path to control the switch operating device to perform one of an open operation and a close operation in a switch.
An operating rod assembly comprising:
- a housing that comprises an open end;
- an insert in the open end, the insert comprising:
- a first wall at a first end, a second wall at a second end;
- and a compressible element in a space between the first wall and the second wall;
- and
- an operating rod configured to be mechanically coupled to a moving contact of a vacuum interrupter, wherein the second wall comprises one or more openings that allow fluid flow between the space and a region exterior to the housing.
A transformer apparatus comprising:
- a housing comprising an interior region configured to receive an electrically insulating fluid;
- a switch in the interior region;
- a switch operating device in the interior region, the switch operating device comprising:
- one or more openings that fluidly couple the interior region of the housing to an interior region of the switch operating device;
- and
- a compressible element in the interior region of the switch operating device;
- and
- an operating apparatus comprising:
- a base;
- a permanent magnet actuator mounted to the base, the permanent magnet actuator comprising an output configured to move along a linear path relative to the base;
- a driving apparatus coupled to the output;
- and
- a crank apparatus comprising at least one crank device, the at least one crank device comprising:
- a fixed pivot point attached to the base, a moveable pivot point attached to the driving apparatus, and a connection point attached to the switch operating device, wherein the at least one crank device rotates about the fixed pivot and the moveable pivot moves the driving apparatus relative to the base in response to the output moving along the linear path to control the switch operating device to perform one of an open operation and a close operation in the switch.
