When the train speed reached to 350 km/h or more, the problem of contact-loss became very serious, so the study on the generated characteristics of discharge with contact-loss of pantograph becomes more and more important. In this paper, designed based on a low voltage and high current experimental platform about the contact-loss of the pantograph-catenary which was designed in the laboratory, at any time in the changed cycle of catenary-voltage, spread out more precisely analysis about the phenomenon and the characteristics of arc discharge resulted from the contact-loss of the pantograph-catenary, the waves of catenary voltage, pantograph voltage, pantograph current, arc voltage and arc light intensity were measured. The results showed that: in the processes of contact-loss, the mutation in the waves of the pantograph-catenary voltage and the pantograph current is obvious, but various in degree with the change of contact-loss times; The light intensity and the current of arc changed with the change of off-line times; The changed process of the arc voltage in various contact-loss times are consistent, but the maintenance time of arcing is different and changing regularly.
