Abstract

The invention discloses an outdoor high-voltage isolated switch which comprises a steel channel base (1), an insulator support column (2), a wire inlet plate (3), a knife switch, an arc protection device, a misoperation prevention mechanism and a wire outlet plate (8), wherein the knife switch comprises a knife plate (4), a locking device (5) and a static contact (7), the locking device (5) comprises a self-locking hook, a self-locking hook spring and a hook ring piece, the self-locking hook and the self-locking hook spring are arranged on the hook ring piece to form a self-locking pull hook, the wire inlet plate (3) is shaped as an L, a part, protruding upwards, of the wire inlet plate is taken as a movable contact and is in contact with the knife plate (7), the movable contact is provided with a through hole, and when the switch is in a closing state, the through hole clamps the self-locking hook of the locking device (5). The outdoor high-voltage isolated switch has the advantages of a simple structure, safety, reliability, no change on production process, low processing cost and a long service life, and the problems of the influence on conductive efficiency due to a crack generated between the movable contact and the wire inlet plate and the like can be effectively solved.

Description

technical field [0001] The invention relates to an isolating switch, in particular to an outdoor high-voltage isolating switch. Background technique [0002] The existing low-voltage fuse-type isolating switch is composed of a mounting base, an insulating porcelain bottle, a connecting plate, an incoming line card, a knife switch, a fuse, and a switching device. The combined switch connects the knife switch and the fuse in parallel and passes through the connecting plate It is arranged on two insulating porcelain bottles, and the knife switch is composed of insulating porcelain rods and connecting components arranged at the ends, and the fuse is arranged between the connectors at the ends of the insulating porcelain rods. For example, the Chinese patent application No. CN200720201627.9 discloses an outdoor low-voltage fuse switch, which includes a base, a static contact seat and a moving contact seat installed on the base, and a fuse piece. A blade with a groove, one end of...
