摘要
电力系统的瞬态恢复电压对真空开关的介质强度恢复影响极大,根据是否考虑这一影响可把真空开关的介质恢复过程分为实际恢复过程和固有恢复过程。本文在相同的实验模型和电路参数下对这两种恢复过程作了比较性的实验研究。提出了“鞘层”与“金属蒸气”相结合的理论模型,并对相关的问题进行了讨论。
Transient voltage in a power system significantly affects the dielectric strength recovery of a vacuum switch. Depending on whether or not this effect is taken into consideration, the dielectric recovery process can be divided into actual recovery and inherent recovery processes. Experimental investigations have been made on both processes under identical conditions and a theoretical model by combining 'sheath' and 'residual neutral' is proposed. Relevant problems are discussed.
