摘要
针对油-纸绝缘系统中的局部放电问题，提出在X射线激励条件下的局部放电检测和定位新方法。实验表明，X射线照射可以电离气体原子，为气隙放电提供必需的初始电子，减小放电的统计时延，从而降低放电的起始电压、增加放电脉冲的次数，这一结果有利于局部放电的检测和定位。
The gas atoms in cavities of dielectric could be ionized by X - ray irradiated. The applicationof X - rays during electrical partial discharge (PD) measuremnt could increase the free electron productionrate in the cavities and decrease the statistical time lag. And compared to conventional PD under the sameelectric stress, not only the amplitudes, and the counts from X - ray induced PD increased greatly, but alsothe discharge regions in the phase angles were enlarged. It is in favor of PD measurement and location that PDwas induced or intensified when dielectric was inadiated by X - ray.
