| 摘要: |
| 相对于常璺双母线接线方式，220kV一个半断路器接线方式下继电保护及相关二次回路要复杂得多，但又与500kV系统有所不同，以500kV泗泾变电站的220kV系统为例，结合上海电网的实际情况，对220kV一个半断路器接线方式下继电保护、二次回路的配置及设计作出探讨，提出了完整的配置方案。 |

| Abstract: |
| Compared with that in conventional 220 kV duplicate bus scheme,the protective relay and secondary circuit in 220 kV bus scheme with one and half breaker are obviously more complicated.It is also different from that in 500 kV system.Taking the 220 kV system of 500 kV Sijing substation as an example,and considering the facts of Shanghai electric power network,the configuration and design of the protective relay and secondary circuit for 220 kV bus scheme with one and half breaker is discussed.A complete configuration scheme is brought forward. |
