The invention discloses a
busbar-disassembly-free insulating protective sleeve, a mounting
handle and a sealing device in the technical field of insulating accessories of
electric power devices, the
busbar-disassembly-free insulating protective sleeve comprises an insulating sleeve sheet and a supporting strip, the insulating sleeve sheet is made of a heat-shrinkable
elastomer insulating material, and the supporting strip is made of a heat-shrinkable
elastomer insulating material. The insulation sleeve sheet is curled towards one side and is closed into a
barrel shape through a closed structure of
butt joint edges on the two sides of the insulation sleeve sheet, the supporting strip is curled on the inner side of the insulation sleeve sheet along with the insulation sleeve sheet to support the
barrel-shaped insulation sleeve sheet, a part to be insulated is rolled on the inner side of the supporting strip, and after the curled supporting strip is pulled out of the
barrel-shaped insulation sleeve sheet, the part to be insulated is fixed on the supporting strip. The insulation sleeve sheet is directly shrunk and wound on the surface of a to-be-insulated part, and the insulation sleeve sheet is taken down from the to-be-insulated part after the closed structure of the
butt joint edge is opened, so that the innovative design of the
thermal shrinkage insulation protection sleeve solves the problems that the insulation protection sleeve of an AC installation
busbar in the prior art is inconvenient to disassemble and needs to be heated, and the insulation protection sleeve is convenient to assemble and disassemble. The beneficial effects of installation without dismounting equipment and on-site cold installation are achieved.
