전기철도 집전시스템 성능평가 기술 분석

In response to increasing interest in speed up of overhead catenary systems, various measurement systems have been developed to evaluate interaction between a contact wire and a contact strip. Contact force, electric arc, and dynamic stagger between overhead contact wire and contact strip are examples of several existing methods for assessment of current collection performance. Additionally, dynamic uplift and strain of contact wire have to be considered, when a pantograph moves at a registration arm. This paper introduces criteria on stability and performance assessment related with speed enhancement for current collection system in electric railway. Tolerance values and measurement techniques of measured items such as contact wire dynamic, contact force, and contact wire uplift were widely mentioned.
