摘　　要：近年来,220 kV变电站中高压配电装置采用GIS设备越来越普遍,根据变电站的规模,220 kV、110 kV GIS接线型式为双母线时,扩建时变电站全部停电的缺点逐渐暴露。通过实例技术经济比较,提出220 kV变电站GIS双母线接线优化为双母线刀闸分段接线的优化方案。该方案的提出,有效地避免了目前变电站扩建时需全站停电的问题。In recent years, Gas Insulated Metal-enclosed Switchgear are applied more popularly at the 220 kV substation. However, the 220 kV substation site-wide blackout will happen during the period of the substation extension and reconstruction, with the double-bus electrical connection applied. Depending on the practical project and based on the technical-economical comparison, the optimized design scheme with the double-bus and Subsection breaker electrical connection applied, is proposed. With this scheme, the substation site-wide blackout can be avoided.
