组合式变压器的保护系统设计

Design for the Protection System on Combined Transformer

对于组合式变压器内部保护系统中各保护配置不合理 ,往往会产生越级保护动作 ,给设备维护或线路的其他设备的正常运行产生影响 ,针对上述问题本文论述如何在设计时避免事故发生 ,合理的配置保护系统中各级保护装置。

Elements to be equipped in the protection system on a combine transformer should be reasonably collocated, if not, a bypass protect action could take place and it could influence the running of other transformer on the same line. This paper describes how to select the protection elements to be equipped in the protection system on a combined transformer for avoiding bypass action.
