The invention discloses a single pipe heat pipe static conductive pole used in a 126KV high voltage vacuum interrupter, comprising a stainless steel sleeve; an oxygen-free copper tube is arranged in the stainless steel sleeve; a tapping and bubble suppression tube is arranged in the oxygen-free copper tube; the stainless steel sleeve and the tapping and bubble suppression tube are coaxially welded on a contact; the oxygen-free copper tube is filled with deionized water; the volume of the deionized water accounts for 15% to 45% of the volume of the oxygen-free copper tube cavity; the oxygen-free copper tube is provided with a sealing cover, and an extractor vent is arranged on the sealing cover. The single pipe heat pipe static conductive pole of the high voltage vacuum interrupter has theadvantages that: heat are transmitted through the phase transition and heat transfer of water, and heat transmission efficiency is higher than that of the static conductive poles having traditional copper bar structure; the i
