摘要
A gas-insulated disconnector includes a movable contact disposed above a fixed contact within a housing filled with an insulating gas. The movable contact is electrically coupled to an upper support member through a finger-type sliding contact 3 which is dip-shaped and is fixed to the support member at the upper end thereof and is in sliding contact with the interior surface of the cup-shaped movable contact. An operating rod connecting the movable contact to a link mechanism is slidably supported by a support cylinder extending within the movable contact. Thus small metal particles generated by the abrasion of the contact surfaces at the side of the movable contact is contained within the movable contact and do not drift into the gas-insulated gap. Further, within the lower shield is disposed a particles remover near a fixed contact, and the small metal particles generated at a sliding contact surfaces of the movable contact 1 and the fixed contact are brushed off the surface of the movable contact 1 into the lower shield.
