| 摘要 |
<p>The present invention relates to a solid-sealed pole which comprises a vacuum arc extinguish chamber, a first conductive terminal and a second conductive terminal. Said vacuum arc extinguish chamber comprises a center axis, a movable conductive rod and a fixed conductive plate. Said first conductive terminal is rotationally symmetrical about said center axis. Said first conductive terminal comprises a circular ring-shaped conductive body and a circular ring-shaped conductive protruding ring attached to the lateral wall of said conductive body. Said conductive body surrounds and electrically connects to said movable conductive rod. Said conductive protruding ring has a plurality of first through-holes. Said second conductive terminal is rotationally symmetrical about said center axis. Said second conductive terminal electrically connects to said fixed conductive plate. The solid-sealed pole of the present invention is small in size and simple in structure, with high safety and reliability.</p> |
