摘要/Abstract

摘要：

电气主接线是变电站工程设计中的一项重要内容。实际工程中有几类特殊接线问题存在争议，例如：一个半断路器接线初期采用2个完整串时元件出口的隔离开关设置、一个半断路器接线在失掉双母情况下仍要保持关键联络通道、高抗回路是否设置隔离开关以及高抗回路接地开关是否可以取消等问题，针对这几个问题进行了分析，提出了相关建议。

Abstract:

The main electrical connection is very important for the design of substations. Several special problems are analyzed and discussed in designing the 3/2 breakers connection and high voltage shunt reactor circuits. These problems include the installation of disconnectors when two complete serials are formed, the retaining of key transmission channels when two buses are cut in the 3/2 breakers connection, and the disconnector and grounding switches in high voltage shunt reactor circuits. Some suggestions with certain reference value for substation designers are proposed.
