摘要
介绍真空断路器投切电容器时产生的过电压种类,采用PSCAD/EMTDC软件对真空断路器操作电容器时产生的重燃过电压进行仿真,分析过电压的产生机理,提出预防重燃过电压产生的有效措施,以保证设备的安全和系统的稳定运行。
This paper presents the over-voltage types during vacuum breaker closing-opening capacitor,and simulates the re-burn over-voltage caused by operating vacuum breaker capacity with PSCAD/EMTDC software,and analyzes the producing mechanism of the over-voltage,and advances the efficient measures to inhibit the produce of re-burn over-voltage,to eusure safe operation of equipment.
