摘要

A vacuum polyphasic short circuit, characterized by being specially composed, although not particularly, of: A) a box provided with a metal roof in communication with earth composed of a notoriously horizontal central plane and two planes symmetrically inclined on each side of said central; B) three independent insulating short tubes respectively located on said three planes of the roof, each one with its geometric longitudinal axis that crosses the respective roof and with the three axes comprised in a practically vertical plane; C) three switches in a respective sealed body each for one of the three phases of the alternating current that is manipulated placed on a respective one of said three insulating tubes; D) an oscillating cord operator member to said switches in a flattened rounded shape with a lateral elongation, located inside the box in a centralized position below said horizontal roof; E) three links respectively connecting the switches with said operator member to transmit them together the movement of the member, and F) said links extend through openings in the canopies and inside the respective insulating tubes.
