Dismounting apparatus for T-shaped pluggable connector of high-voltage cable

The invention relates to a dismounting apparatus for a T-shaped pluggable connector of a high-voltage cable. The dismounting apparatus comprises a lead screw, a torsion bar, a limiting bracket, a sliding bracket and a hoop, wherein the limiting bracket is fixed on the lead screw through a fastening nut; a sliding way is formed in the inner side of the limiting bracket; the sliding bracket is glidingly arranged in the sliding way in the inner side of the limiting bracket; one end of the sliding bracket is movably connected with the lead screw through the nut while the other end of the sliding bracket is connected with the hoop; and the end of the lead screw is connected with the torsion bar through an ejecting cap. The dismounting apparatus mainly adopts the mechanical conversion process of the reaction thrust of the main force shaft of the lead screw, so that convenient and force-saving dismounting is realized; and meanwhile, the dismounting apparatus is safe and reliable, and simply and conveniently solves the problem of difficulty in on-site dismounting of the T-shaped pluggable connector of a ring main unit and a cable branch box.
