Abstract

A slider of the pantograph undergoes uneven and abnormal wear due to sliding contact with the catenary. In the case of rain, the loss of lubricant increases the frictional resistance for the reciprocating motion between the catenary and the slider, accelerating local wear. The slider in the winter should have good wear resistance, which can be achieved through alloy design. Uneven and abnormal wear were not observed in the results of a driving test using a wear resistant slider. It was found that the increased density of the slider enhanced the corrosive effects of Fe-Ti, preventing the occurrence of abnormal wear by maintaining the wear and arc resistance in the rainy season. Also, mechanical and electrical wear did not affect the composition of the slider, and this improved the wear resistance. Inaddition, the slider was applied to an entire train and was tested during driving; ananalysis of the correlation of the catenary was performed, including during the rainy season and the winter season.

VVVF 전동차 팬터그래프의 주습판은 전차선과 미끄럼 접촉에 의한 집전을 하면서 편마모 등 이상마모 현상이 나타나게 된다. 우천 시에는 윤활성분이 손실되어 주습판과 전차선과의 왕복운동에 대한 마찰저항이 급상승하여 국부적 마모가 가속화 된다. 내마모 특성을 가져야 하는 동계 주습판의 특성을 고려하여 합금설계를 통해 제작된 개선 주습판의 현차시험 결과 이상마모와 편마모가 발생하지 않았다. 개선된 주습판의 밀도향상은 Fe-Ti의 부석효과를 상승시켜 우기 시에도 우수한 내마모성 및 내아크성을 유지함으로써 이상마모 발생을 방지하였다. 또한, 기계적, 전기적 마모에 의한 주습판의 성분 및 조성변화가 일어나지 않았다. 주습판의 내마모성 향상에 기여함과 더불어 우기와 동절기 등 악 조건하에서 현차시험을 거치고 전차선과의 상관관계도 분석하여 전 전동차에 적용하였다.
