摘　　要：以天津张贵庄污水处理厂35 kV变电站设计案例为基础,探讨了35 kV变压器继电保护的选择,并介绍了以纵联差动保护作为主保护,以过电流保护作为后备保护的变压器继电保护设计。同时给出了相关参数的整定及保护灵敏度校验的计算过程。Based on the design of 35 kV substation in Zhangguizhuang WWTP, the selection of relay protection of 35 kV transformer was discussed, and the design of relay protection which uses the longitudinal differential protection as main protection and the overcurrent protection as backup protection was introduced. At the same time, the method of setting relevant parameters and the calculation and calibration of the protection sensitivity were given.
