Preliminary Study on Making Arc Characteristics of AgSnO2 Contact

Abstract

In order to analyze the making arc characteristics of AgSnO<sub>2</sub> contact, experiments were carried out with a self-developed experimental equipment. It was found that contact resistance had no obvious change with the increase of the number of experiments.In the later stage of the experiment, the contact bounces occurred during the contact closing process, which not only prolonged the making arc duration, but also increased making arc energy. When the contact was eroded to a certain extent by arc, making welding occurs.
