OCS, an important component of the traction power supply system in urban rail transit, provides continuous and stable electrical energy to electric motor coaches through sliding contact with the pantograph. Therefore, its dynamic operation quality is crucial for the safe operation of the line. At present, the management of OCS equipment in urban rail transit industry is still based on the traditional static geometric parameter threshold management method. It is only able to confirm the static state of OCS, but it is difficult to analyze the OCS dynamic performance and pantograph-catenary relationship under load conditions. The paper, with application of relatively mature train-carried 3C dynamic inspection technology for pantograph and catenary, with comprehensive consideration of various parameters that affect the dynamic relationship between pantograph-catenary, carries out the research on the dynamic operation quality evaluation index CDI of OCS of urban rail transit based on national or industry standards and enterprise refinement standards, intending to establish a scientific and comprehensive equipment dynamic quality evaluation system and standards, and to visually quantify the dynamic performance of OCS, facilitating the management of in-service equipment.
