摘要：
Aiming at the process of DC vacuum interruption with artificial current zero, some main factors influencing on the vacuum breaking characteristic are analyzed and studied in this paper. And the DC vacuum interruption process is verified by the prototype test. The research results indicate that the post arc dielectric recovery characteristic for a high current vacuum arc could be improved, prompting a more reliable interruption process through some improvements as followed. The post arc initial metal vapor density may be reduced by speeding up the DC fault detection and the fast vacuum switch (FVS) breaking. A much lower current rate of fall after zero could be realized with a saturable reactor connected with the FVS in series. Adding a resistor & capacitor snubber parallel connected with the FVS will make the post arc transient recovery voltage rise more slowly. And the vacuum arc anode spot could be avoided though a optimum design of FVS breaking movement characteristic and arcing interval. The achievement in this paper is worthy for development of a practical DC VCB. © 2019, Harbin University of Science and Technology Publication. All right reserved.
