Abstract

Pre-application of low ac V( suppresses ac tree initiation in pure LDPl no additive. This "training effect' different from the so called "voltage harc effect" in additive doped samples. Ac v( application produces the deteriorated reg. high field area, which is the preci phenomena of tree initiation. The experir results suggest that the training effec closely related to the formation deteriorated region. This paper also des( the ac pre-stressing effect on impulse initiation.

交流预应力对电气树启动的影响——交流电压训练的机理

预施低交流电压抑制纯LDPl中无添加剂的交流树形成。这种“训练效应”不同于添加剂掺杂样品中所谓的“电压效应”。交流电的应用产生变质的reg。高场区，这是树木形成的精确现象。实验结果表明，训练效果与地层变质区域密切相关。本文还研究了预应力对冲击起裂的影响。
