Abstract
An assembly includes an automatic transfer switch having an operating mechanism. The operating mechanism is configured to cause current to flow through the automatic transfer switch. The assembly further includes a cooler configured to cool at least a portion of the automatic transfer switch. The cooler is structured to be wirelessly driven by electromagnetic fields generated in response to current flowing through the automatic transfer switch.
Claims24
An assembly, comprising:
- an automatic transfer switch comprising an operating mechanism configured to cause current to flow through the automatic transfer switch;
- and
- a cooler configured to cool at least a portion of the automatic transfer switch and structured to be wirelessly driven by electromagnetic fields generated in response to current flowing through the automatic transfer switch.
A system comprising:
- an automatic transfer switch comprising
- a plurality of switch components comprising respective pluralities of cassettes;
- at least one conductor configured to generate a magnetic field in response to current flowing through the conductor;
- a permanent magnet;
- and
- a driven shaft driven by rotation of the permanent magnet in the magnetic field;
- wherein a polarity of the magnetic field is configured to change in accordance with an alternating current of the automatic transfer switch.
