High-voltage loadbreak switch with enhanced arc suppression

A poly-phase loadbreak switch for switching a high-voltage poly-phase power source, the switch comprising:

• a first phase switch configured to switch a first phase of the high-voltage poly-phase power source;
• a second phase switch configured to switch a second phase of the high-voltage poly-phase power source;
• and
• a first baffle configured to separate about all of an arcing region of the first phase switch from about all of an arcing region of the second phase switch to suppress arcing between the first phase switch and the second phase switch, wherein the first baffle comprises a non-conductive material.

A three-phase loadbreak switch for switching a high-voltage three-phase power source while submersed in a dielectric fluid, the switch comprising:

• a first rotating switch configured to switch a first phase of the high-voltage three-phase power source;
• a second rotating switch configured to switch a second phase of the high-voltage three-phase power source;
• a third rotating switch configured to switch a third phase of the high-voltage three-phase power source;
• a first baffle configured to intervene about entirely between the first rotating switch and the second rotating switch to suppress arcing between the first phase and the second phase of the high-voltage three-phase power source;
• a second baffle configured to intervene about entirely between the second rotating switch and the third rotating switch to suppress arcing between the second phase and the third phase of the high-voltage three-phase power source;
• wherein the first, second, and third rotating switches each comprise a paddle configured to circulate the dielectric fluid.
