| 摘 要： | 为了研究并联间隙装置对绝缘子串电压分布特性的影响，用有限元法建立了220kV输电线路复合绝缘子三维电场计算模型来研究加装不同并联间隙装置后的绝缘子电压分布，并和加装均压环后电压分布进行对比。计算结果表明：环形并联间隙对绝缘子的均压效果明显优于棒形并联间隙，环形间隙环径越小，管径越大，其改善复合绝缘子端部的电场及电压分布...

| Abstract: | In order to analyze the impact of parallel gap lightning protection device(PGLPD) on the voltage distribution along insulators,taking 220 kV composite insulators as example,we established a three-dimensional electric field calculation model of composite insulators of the transmission line by the finite element method.The impact of different types of PGLPD on the voltage distribution along insulators is analyzed.The voltage distribution along insulators when PGLPD and shielding rings is employed separately i... |
