低海拔地区长空气间隙放电特性试验研究
Experimental Research of Long Air-Gap Discharge Characteristics in Low Altitude Area
摘要
Abstract
In order to improve the external insulation design of UHV transmission lines, the discharge experiments of rod-plate long air gap under DC voltage, lightning impulse voltage and operating impulse voltage are carried out in Nanning, and it proves that the discharge voltage of rod-plate air gap with positive polarity is much lower than that with negative polarity. The experimental data are corrected with related standards, and then the results are compared with the data of rod-plate discharge in China Electric Power Research Institute in Beijing, which is in almost the same altitude as Nanning, showing that the correction methods recommended by IEC 60060-1, DL/T 620-1997 and 1EC 60060-1 are good for the positive discharge test in plain and that by DL/T 620-1997 are mainly for power frequency discharge voltage and positive impulse discharge voltage.关键词
