摘要
叙述了北京地区220 kV旁路代路时,根据被代路开关不同的继电保护的配置,旁路开关也应做一定的继电保护配置,使代路时的旁路保护也能满足可靠、选择、灵敏、速动的要求。分析了代路操作时一次系统的变化对继电保护的影响,提出了旁路代线路开关时继电保护的几种操作方案。还对旁路开关代变压器高压侧主开关的注意事项进行了初步分析。
When switching 220 kV bypasses in Beijing Area, according to the relay protection configurations of different cutted switches, the bypass switches should be also configured to satisfy the reliable,selective, sensitive and quick demands. This paper analysed the influence on relay protection as primary system changes because of the bypass replacement. And several operation schemes of relay protection were given in this paper too. In the end, an preliminary analysis was described about the precautions in switching the bypasses of high voltage switch of transformer.
