中文摘要: 运用EMTP软件,通过电压分布法对劣化绝缘子、零值绝缘子和不同绝缘子片数的绝缘子串进行仿真,分别得出不同状态下绝缘子串的电压分布特征.结果表明,绝缘子串的前3片出现故障时,整个绝缘子串的电压分布的不均匀程度最大;绝缘子串的绝缘子片数越多,其电压分布越不均匀.
Abstract:Through the voltage distribution method, the voltage distribution characteristics under different states of insulator strings are obtained. The result shows that, when the first three pieces of insulator string become deteriorated or zero, the uneven degree of insulator string voltage distribution is maximized. In addition, the more insulator pieces there are in an insulation string, the more uneven the voltage distribution is.
