Since gag insulated switchgears (abbreviated GIS) are the most suitable kind of switchgears to be used in circumstances of heavy contamination and insufficient space for installation, a number of 220-500 kv GIS substations are planned to be built in China recently.

本文研究超高压SF_6全封闭变电站(简称GIS),特别是大型水电站GIS的侵入波保护问题. 研究是在新设计的模拟上进行的,对于500千伏GIS的研究,在国内还是首次. 文中着重研究了侵入波陡度,避雷器的台数、型式和位置,设备的参数,并联电抗器的位置,进出线数目,以及接地情况等影响因素.根据研究结果,提出了GIS侵入波保护的可靠方式,可供我国电力设计工作者今后设计GIS的防雷保护时应用.

This paper introduces a method to calculate the three-dimensional electric field in a substation. Distribution of the field fixed up at will can be calculated by the application of the charge substitution method accompanied with suitable coordinate transformation. Results from both model experiment and field measurement show that the proposed method and program are available. General equations for calculation of potentials and intensities of the electric field are given . Besides, a new method for determining the extreme value and direction of electric field intensity is derived and proved.

Recently as the system configurations experienced great changes in our country, higher requirements are now being put foward for main electric circuits of large pouer stations and substations. "3/2 Breaker Circuit" has been adopted in most designs for many years. By analysing and calculating the reliability indices of both "3/2 Breaker Circuit" and "4/3 Breaker Circuit" , this paper shows that the latter should be adopted in practice.

目前由于我国电力系统的结构发生了很大的变化,对发电厂和变电站的电气主接线便提出了更高的要求。以往的设计中大多数是采用“3/2”断路器接线。本文通过对“3/2”断路器接线与“4/3”断路器接线可靠性指标的分析计算,说明在实际工程中,“4/3”断路器接线也应考虑采用。
