摘　　要：由于起动/备用变压器特殊的主接线和运行方式,使得起动/备用变压器保护的设计和配置有别于其他类型的变压器保护。文章介绍了CSC316B微机型起动/备用变压器保护装置的设计和功能。讨论了起动/备用变压器在工程配置和整定时需要考虑的特殊问题,如高低压侧二次额定电流相差太大时对差动保护实现的影响,高低压侧短路后备保护和接地后备保护的配置及整定等问题。Because of special wiring and operation mode for start/standby transformer, the design and disposition of protection for start/standby transformer are different from other types of transformer protection. The design and function of CSC - 316B micro - computer protection were introduced, which is new R ＆ D for start/standby transformer. The special problems to be considered when disposition and settings of protection were discussed, such as the influence of big differences between secondary rated current in high and low voltage side on differential, protection realization, the disposition and settings for back - up protection of short circuit in high and low voltage side and grounding back - up protection etc..
