A long-term tracking test is carried out on the geometric parameters dynamic performance of catenary,the static pressure of pantograph and arcing performance of pantograph and catenary of a 350 km/h high-speed railway.The arcing times and the dynamic contact force of pantograph and catenary,the dynamic uplift of catenary,the load borne by catenary components and the change law of sliding plate wear are compared at different operating speeds,the contact line wear is analyzed,and the contact line life is predicted.Finally,the service life of catenary components is approved by bench test.Through above tests and research,the service performance of OCS equipment at the operating speed of 350 km/h of EMU is fully mastered,which provides data support for the maintenance of OCS equipment.
