Problems solved by technology

However, the greater the current, the greater the skin effect, so it is uneconomical to use solid rods to make conductive rods, resulting in waste of resources
[0005] At the same time, shed sheds are usually distributed on the outside of the outgoing line insulating sleeve. Conventional epoxy cast outgoing line insulating sleeves will use an integrated epoxy cast shed. Due to the large volume and weight of the entire sleeve, it is difficult to It is easy to bump and damage the protruding umbrella skirt, affecting normal use
[0006] The outlet insulation bushing used by GIS switchgear is usually cast with an insert with internal thread on the bushing, and is connected to the gas box through bolts. Once the upper end of the bushing is subjected to lateral tension, the steel plate at the bolt connection will be partially deformed. Severely will affect the sealing performance

Abstract

The invention discloses an outgoing line insulation sleeve, which comprises an outgoing line sleeve main body, a heightening joint, a silicone rubber insulation piece, a fastening connection device and a silicone rubber umbrella skirt. The heightening joint can be spliced with the outgoing line sleeve main body to increase the outer insulation height of the outgoing line sleeve. The silicone rubber insulation member is in interference fit with the outgoing line sleeve main body and the heightening joint to form a stable insulating layer to prevent the electrified body at the joint portion frombeing discharged to the outside. The silicone rubber umbrella skirt is wrapped in the surface of an epoxy insulation layer of the outgoing line insulation sleeve. The invention provides an outgoing line insulation sleeve, which is a combined splicing type outgoing line insulation sleeve, and can be configured with a suitable outer insulation height of the sleeve according to different needs. Thecost of raw materials and the weight of the product are reduced, the installation strength is increased, the product umbrella skirt is not easy to damage, and at the same time the installation and positioning of the outgoing line insulation sleeve is facilitated.

Description

technical field [0001] The invention relates to an insulating bushing for outgoing lines, which belongs to the field of high and medium voltage switchgear. Background technique [0002] At present, in the field of high and medium voltage switchgear, the main function of the outlet insulating bushing is to introduce the high voltage potential of the overhead line or cable into the metal fully enclosed GIS switchgear, so as to complete the operation of opening, closing and isolating the line. . [0003] When the insulating bushing for outgoing wires is used in high-altitude areas, the part exposed to the air needs to increase the electrical clearance, so the insulating bushing needs to be increased. The present invention solves this difficult problem conveniently and quickly by adopting a combined splicing method. [0004] The conductive rod is the current-carrying part of the outgoing insulating sleeve. Usually, the conductive rod is processed from a solid rod, and a rod wi...
