Abstract
A device for switching a handle of an electrical switch has at least a first actuator and a second actuator. When the device is installed on the electrical switch, the first actuator can move the handle in a first direction and the second actuator can move the handle in a second direction opposite the first direction. The first actuator and the second actuator are shape-memory alloy actuators.
Claims10
A device for operating a handle of an electrical circuit breaker, the device comprising:
- a first actuator and a second actuator;
- with the device mounted on the electrical circuit breaker, said first actuator being configured to move the handle in a first direction and said second actuator being configured to move the handle in a second direction, which is opposite to the first direction;
- a carriage configured to enclose the handle of the electrical circuit breaker when the device is mounted on the electrical circuit breaker and to operate the handle by a movement of said carriage, and said first actuator being configured to move said carriage in the first direction and said second actuator being configured to move said carriage in the second direction opposite the first direction;
- and
- each of said first actuator and said second actuator being a shape-memory alloy actuator.
2 more elements
A multi-function operator, comprising:
- a housing;
- a device for operating a handle of an electrical circuit breaker disposed in said housing, said device having:
- a first actuator and a second actuator, each of said first actuator and said second actuator being a shape-memory alloy actuator, and
- with the device mounted on the electrical circuit breaker, said first actuator being configured to move the handle in a first direction and said second actuator being configured to move the handle in a second direction, which is opposite to the first direction;
- and
- said housing being configured for mounting the multi-function operator to the electrical circuit breaker and, with the multi-function operator mounted to the electrical circuit breaker, the first and second actuators of the device are disposed to set the handle of the electrical circuit breaker in motion for switching the electrical circuit breaker;
- and
- at least one operator knob configured, upon an activation thereof, to set the actuators of said device in motion, and said at least one operator knob being connected to remaining elements of the multi-function operator by an electrical connection or a wireless connection.
