利用计算机仿真技术
对该次爆炸事故进行了深入分析
得出了均压电容本身存在绝缘缺陷
在开关发生一次重击穿时发生爆炸的结论。
Abstract
A grading capacitance explosion occurs during switching no-load in 500 kV long line. According to the field fault oscillograph
thorough analysis is made to the accident by computer simulation technology. The result is concluded that insulating defect exists in grading capacitance itself
