Problems solved by technology

Due to the limited space of the roof structure, the supporting insulators are easily polluted, resulting in flashover breakdown or even bottle explosion, resulting in frequent occurrence of vicious accidents such as pantograph and catenary burnout, and locomotive shutdown.

Abstract

The invention discloses a high-strength insulation material pantograph which comprises a sliding plate mechanism, a lifting frame, a supporting frame, an under frame, a driving system and an insulated cable, wherein the sliding plate mechanism is a current collection mechanism of an elastic floating-support sliding plate, and can reduce the influence of the engine vibration and the electric network height oscillation on the current collection quality; the lifting frame and / or supporting frame are / is made of a high-strength insulation material, thereby having several times of the electrical insulation property required by the catenary system and needing no support insulators, and the collected current of the sliding plate is transmitted by a special insulated cable; the driving system drives a drive bolt by an automatic gear shifting motor, thereby lifting the pantograph at variable speeds; the insulated cable of the invention is a braided wire cladded by special insulation rubber; and the under frame of the invention is directly fixed on the vehicle top. The invention has the advantages of good current collection quality and safe and reliable insulation, and can be widely used in high speed and high power electric locomotives and motor train units.

Description

technical field [0001] The invention relates to a pantograph, in particular to a pantograph for an electric locomotive and an electric train set, which is made of high-strength insulating material and has an elastic floating slide plate. Background technique [0002] The operation of electric locomotives and EMUs depends on the quality of the pantograph receiving current from the high-voltage catenary. Generally, pantographs can be divided into single-arm bows and double-arm bows, both of which are composed of slide plates, upper frames, lower frames, underframes, bow springs, transmission cylinders, supporting insulators and other components. [0003] At present, pantographs at home and abroad are all comprehensive high-voltage electrical equipment made of metal materials with current receiving and power transmission functions. Reliable insulation and fixing between pantographs and locomotives are required to work through special support insulators. Due to the limited stru...
