Pantograph insulation bow angle and pantograph

Abstract

The invention discloses a pantograph insulation pantograph corner. The pantograph insulation pantograph corner is applied to pantograph, and comprises a metal pantograph corner main body (1) and a non-metal pantograph corner end head (2); the metal pantograph corner main body (1) is connected with a body of the pantograph; the non-metal pantograph corner end head (2) is fixedly connected with themetal pantograph corner main body (1); the metal pantograph corner main body (1) is made of a pipe; the non-metal pantograph corner end head (2) adopts a solid bar material, and the outer diameters ofthe metal pantograph corner main body (1) and the non-metal pantograph corner end head (2) are the same. According to the pantograph insulation pantograph corner, the structure is simple, the use isconvenient, the metal pantograph corner scheme and the non-metal insulation pantograph corner scheme are combined, the actual application is met, and meanwhile, the new manufacturing and overhauling cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to an insulating bow angle of a high-speed pantograph and a pantograph. Background technique [0002] Two bow angles are symmetrically arranged on the left and right sides of the bow head of the pantograph, mainly to prevent the catenary from drilling under the bow head of the pantograph to damage the catenary or pantograph when the vehicle is running, causing pantograph-catenary accidents. Therefore, the following three factors are mainly considered in the design of the bow angle: [0003] 1) The outline of the bow head (bow angle length and height) must meet the limit requirements; [0004] 2) The strength and hardness of the bow angle must bear the pantograph-catenary load requirements; [0005] 3) Lightweight design, which is especially important for high-speed pantographs. [0006] At present, the bow angle of the pantograph is usually made of metal circular pi...

Problems solved by technology

[0006] At present, the bow angle of the pantograph is usually made of metal circular pipe. When the bow is in the bow position, the distance between the bottom of the bow angle and the roof is often the lowest point of the electrical clearance. discharge phenomenon

[0007] In another existing technology, in order to prevent partial discharge, the first thing that comes to mind is to use non-metallic insulating material for the bow angle as a whole, but after a period of application, it is found that the bow angle of this technical solution is not wear-resistant, easy to crack, and difficult to Disadvantages such as weight loss, high cost of new construction and maintenance
