In order to get the knowledge of gas dynamics in interruption process of molded case circuit breakers, a quenching chamber model with gas-driven arc is proposed. The two-dimensional optical fiber digital testing system has been used to measure the arc current, arc voltage, pressure in the quenching chamber, and the movement of the arc when interrupting the 10kA prospective current in different conditions. The influence of venting conditions, the configuration of splitter plates and gassing material characteristics on the performance of gas-driven arc has investigated. It demonstrates that the performance can be improved effectively by the ways of closing the bottom venting, adopting shorter splitter plate configuration, and POM and Nylon gassing materials.
