The invention discloses a sealing device for dust-free installation and butt joint of GIS equipment. The sealing device comprises an annular sealing cover. The annular sealing cover is composed of twosymmetrical semi-cylindrical dust covers. Semicircular pipe grooves are formed in the vertical faces of the two sides of the dustproof cover correspondingly, and semicircular flange plates are arranged on the vertical faces of the outer sides of the semicircular pipe grooves correspondingly. Pipeline sealing sleevelets are arranged on the semicircular flange plates respectively; an observation window and a hand hole are respectively formed in the dustproof cover; and arm sealing sleevelets are arranged on the hand holes. The semi-cylindrical dust covers are in butt joint to form an annular sealing cover, the semi-circular pipe grooves are in butt joint to form a circular pipe groove and clamp a pipeline, and the semi-circular flange plates are in sealed butt joint with the pipeline through the sealing rubber ring
