| Abstract |
The catenary of the overhead single-wire country catenary is a contact wire that supplies power by mechanically and electrically contacting the pantograph (collection plate) of an electric rail vehicle whose position of power load changes. are using.
In this paper, power failures occurring in the transmission and substation facilities and distribution lines of railways, centered on domestic catenary lines for the past 5 years(from 2016 to 2020), are classified by the type of failure cause, and the cause of the failure is the type of the catenary line.(7 types): Model the relationship between design errors, material defects, construction defects, negligence in maintenance, work negligence, foreign substances, and parts aging into life cycle stages(construction⇒operation⇒ disposal), and By applying the bathtub curve, which is a failure rate curve, the simulation results from a life cycle perspective derived a life cycle relationship between the causes of power failure in the overhead single-wire catenary. |
