Pantograph carbon slider assembly and abrasion detection method for same

Abstract

The invention discloses a pantograph carbon slider assembly and an abrasion detection method for the same. The pantograph carbon slider assembly comprises a pantograph and a support for supporting thepantograph, wherein a detecting groove is formed in the reverse surface of the end, which is in contact with a cable, of the pantograph; a variable-resistance block is mounted in the detecting groove; an insulating plate is fixed on the bottom surface of the variable-resistance and is made of an insulating material; the insulating plate is fixedly connected with the top of a tightening shaft; thebottom of the tightening shaft penetrates through a guiding groove formed in the support and a fixed plate arranged in a protecting shell and then is fixedly connected with the top of a guiding column; the fixed plate is arranged in a cavity of the protecting shell; a spring sleeves the guiding column, and the bottom of the guiding column and the inner barrel of a tightening head are assembled; the outer wall of the tightening head and the protecting shell are assembled in a thread screwed manner; the tightening shaft and the fixed plate can be assembled slidably; and the resistance of the variable-resistance block is greater than that of the pantograph. The pantograph carbon slider assembly is simple in structure and convenient to use; whether the pantograph carbon slider assembly needsto be changed or not can be judged accurately; and the pantograph carbon slider assembly is low in manufacturing cost and suitable for being popularized widely.

Description

technical field [0001] The invention relates to the technical field of pantographs, in particular to a carbon sliding plate assembly of a pantograph and a wear detection method thereof. Background technique [0002] The pantograph is the electrical equipment used by the electric traction locomotive to obtain electric energy from the catenary, and is installed on the roof of the locomotive or motor car. When in use, the grid voltage of 25000V is about 400A or less (depending on different types of vehicles), and the current is transmitted to For electric traction locomotives, due to long-term close contact and high-speed sliding, the carbon slide plate on the pantograph is very easy to wear. The carbon skateboard must be replaced after the wear exceeds a certain level, otherwise there will be a greater safety hazard. [0003] At present, although there is a real-time monitoring equipment for pantograph wear, it is relatively expensive, and the pantograph needs to be replaced...

AI Technical Summary

Problems solved by technology

When in use, the grid voltage of 25000V is about 400A or less (depending on different types of vehicles), and the current is transmitted to For electric traction locomotives, due to long-term close contact and high-speed sliding, the carbon slide plate on the pantograph is very easy to wear

The carbon skateboard must be replaced after the wear exceeds a certain level, otherwise there will be a greater safety hazard

[0003] At present, although there are real-time monitoring equipment for pantograph wear, it is relatively expensive, and the pantograph needs to be replaced only when it is worn to a certain extent, so it is not necessary to detect the wear degree in real time
