| 摘 要： | 通过缩小尺寸的杆塔和导线的模拟试验研究了设计中的三沪直流输电线路极导线垂直排列的电场问题。测量和对比分析不同极导线高度和排列时的合成场强及其分布,结合直流线路标称场强的计算,认为导线电晕现象越严重,产生的离子越多,直流合成场强比标称场强就越大。研究表明,极导线水平排列比垂直排列的线下合成场强要高,高场强区宽,而且三沪直流线路极导线采用垂直排列且上负下正时合成场强较低。

| Abstract: | This paper studies the electric field under the polar conductors in vertical arrangement on San Hu DC line. Having analyzed and measured the total electric field of the model DC line in different conductors arrangement and with several conductors height, it is considered that conductors corona is more intense, more ion is generated, and the total electric field strength is greater than the nominal electric field strength. It is also indicated that the total electric field strength of polar conductors in horizontal arrangement is greater than that of the polar conductors in vertical arrangement. It is suggested that the negative conductor is in bottom in vertical arrangement for San Hu DC line and the total electric field strength is lower in that case. |
