Abstract

The present invention discloses a composite insulator suitable for the top high-voltage strut of electric locomotive, wherein the composite insulator comprises an upper cover (1), an upper connector (2), a silicon rubber sleeve (3), an insulator (4) and a base (5). The insulator (4) is connected with the upper cover (1) through the upper connector (2). The insulator (4) is externally installed with the silicon rubber sleeve (3). The base (5) is installed below the insulator (4). The inner core of insulator (4) is epoxy fiberglass rod. The silicon rubber sleeve (3) adopts a high molecular polymer with modified silicon rubber as base material. The composite insulator according to the invention has the advantages of excellent electric insulating property, excellent electric corrosion resistance, excellent aging resistance and excellent hydrophobicity so that the insulator has strong contamination resistance thereby guaranteeing the reliable operation of electric locomotive. The inner core of insulator has excellent electric insulating property and excellent mechanical property. The electrical strength, tensile strength and bending resistance are much better than the high-strength ceramic. Simultaneously the composite insulator has excellent vibration resistance and excellent creep resistance. The whole mechanical and electric properties of insulator are increased.

Description

technical field [0001] The invention belongs to a special insulator for an AC electrified railway locomotive, in particular to a composite insulator suitable for high-voltage pillars on the top of an electric locomotive. Background technique [0002] At present, porcelain insulators are mostly used on electric locomotives. The overall mechanical and electrical properties of porcelain insulators are low, and their electrical insulation performance, electrical corrosion resistance, aging resistance, shock absorption performance, and creep resistance are weak. The electrical strength and tensile strength of porcelain insulators are weak. Poor strength, bending strength, and pollution resistance, high maintenance costs, and large manpower input. Contents of the invention [0003] The present invention is to solve the problem of low overall mechanical and electrical properties of porcelain insulators, weak electrical insulation performance, electrical corrosion resistance, anti...
