摘要

为研究直流输电电压下的油纸绝缘特性

设计并搭建了交流变频高压试验电源系统

并设计制作了典型的油纸绝缘局部放电试品模型

即纸板内部气隙放电、油中纸板沿面放电和油中金属尖端电晕放电模型

针对不同频率电压作用下的同一试品

进行局部放电测量

通过分析获得了局部放电随电压频率升高发生相位、幅值、等变化的放电规律.试验与分析结果表明

随外施电源频率增加及电压幅值升高

局部放电次数增高

能量有所增强

亦即随频率的增加油纸绝缘结构受到局部放电的威胁越严重.研究结果对直流输电系统中的换流变、平波电抗器等油纸绝缘在谐波电压作用下绝缘结构设计有指导意义.

Abstract

To investigate the characteristic of oil-paper insulation under DC transmission voltage

a high voltage frequency-variable test power source is designed and constructed. The typical oil-paper insulation partial discharge models are established according to the discharge in inner air gap of insulating press board

the discharge on surface of insulating press board in oil

and the corona discharge at metal tip in oil. The partial discharge is measured for the same test sample under different frequency voltages to find the frequency and energy of partial discharge increasing with the frequency and amplitude of AC power source.The analysis report indicates that the phase position

amplitude

and frequency of partial discharge are affected by different frequencies

namely

oil-insulation structure holds heavy electrical field while the frequency increases. This study may be helpful in designing insulation structure of converter transformer and smoothing reactor for DC transmission system.
