超高压输电线路电气强度特性的综合和相间允许距离的选择

Generalization of Electric Strength and Choice of Admissible Inter Phase Distance of EHV Transmission Lines

本文分析了相间绝缘系统操作冲击的试验结果,得出了超高压架空线路和变电所的不同绝缘结构的相似判据,提出了形成多极绝缘系统的放电特性的形式,这种形式可在不做试验的情况下用以计算放电电压。

Phase-to-phase insulation systems switching surges experimental test resuls were analized. The similar criteria of different construc-tion EHV overhead lines and substation insulation systems were find. A form for generalising the multi-electrode insula tion systems characteristies is given. The form is allowed to calculate flashover voltages without experimental tests.
