组合式变压器的保护系统设计

Design for the Protection System of Combined Transformer

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带来影响。针对这一问题 ,本文论述了如何在设计时避免事故发生和合理地配置保护系统中各级保护装置。

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