Abstract

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 layers to guarantee that the interior of the annular sealing cover is isolated from the outside. A person stretches an arm into the hand hole and carries out related operation, and the operation condition can be clearly seen through the observation window. The pipeline sealing sleevelet and the arm sealing sleevelet are both provided with elastic bands, and therefore thesealing performance of the joint can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sealing devices for electrical equipment, and in particular relates to a sealing device for dust-free installation and docking of GIS equipment. Background technique [0002] In the prior art, according to the requirements of the State Grid Corporation and the Provincial Corporation, dust-free installation is required for GIS equipment. Because GIS equipment is a combination switchgear with compact structure and small volume, it combines the live busbar and switchgear in a sealed container, and the SF is filled in the container. 6 The gas is insulated, so the requirements for the purity, cleanliness and temperature of the gas in the container are extremely strict. The temperature must be guaranteed at -10 to 40 degrees, the humidity is less than 80%, and the cleanliness is above one million grades. In order to ensure the purity and cleanliness of the equipment and gas during the installation process, so ...
