Catenary and Pantograph from Apt of Electrical Animation

Abstract

This article has been contemptuous to recapitulate from the performance of the catenary and pantograph. The addition of electricity inclusive from the instant of cable to tough catenary has been synergistic to usual corrosion. Effects of arc ablation on abrasion losses of pantograph strips have ever conspired. In presence of arc discharge temperature distributions of pantograph strips and catenary wires have been analyzed. Suggestive one of key parameters has studied contact resistance to reflect current collections i.e. perform under variations of contact resistance of pantograph and catenary system. Option possibility has linked analytic under various electric current and normal forces, so forth static contact condition has analyzed to sub verb transient current collection. Referred apt have a descriptive issued variation of contact resistance with time, climate, and involved temperature distribution. Differential variable variation issued for slide contact has been friction effects and arc discharge that has derived from a disconnection between pantograph strips and catenary wires. Significance has linked influence from temperature rise and microstructure differential. Ethical has involved adding spatial temperature distribution that has been a circus effective reference for estimation of contact status. Microstructure analysis has involved assessing wear mechanisms for sliding electric contact of pantograph/contact wire systems. Characteristics of sliding electric contact as said toward contact resistance, temperature distribution and microstructure have been suggested as well as during zigzag movement, where contact resistance has been deduced by recorded voltage and current waveforms, so forth, correction inclusive has synchronized to assessed temperature distribution as achieved from the infrared thermometer.
