Low-pollution support insulator, high-speed train and method

Abstract

The application provides a low-dust-supporting insulator, a high-speed train and a method. The low-dust-supporting insulator comprises a core rod and a plurality of umbrella skirts arranged axially along the core rod, and the core rod and / or the umbrella skirts are provided with a dust-suppression cross section, which comprises one ellipse and two sharp corners. The vertexes of the sharp corners are located at the outer ends of the major axis of the ellipse. The sharp corners are composed of two tangent straight lines of the ellipse. The length of the major axis of the ellipse is in the same direction as the length direction of the body of the high-speed train, and the length of the minor axis is b , the distance from the vertex of the sharp corner to the center of the ellipse is c . The dirt accumulation degree of the supporting insulator can be linearly increased according to the width-to-sharpness ratio. Compared with the common circular cross section of the supporting insulator, the dust-suppression cross section of the supporting insulator provided by the application for the high-speed train pantograph bottom supporting insulator can have good low-dust-accumulation effect and low wind resistance effect in the running process under the premise of meeting the mechanical requirements and manufacturing process requirements.
