摘 要： 建立了220 kV 變電站典型模型，介紹了旁路代線路開關(guān)和旁路代主變變高開關(guān)的操作過程、注意事項(xiàng)及常見故障。指出旁路代路的主要過程為保護(hù)定值的整定及對旁路母線充電、代開關(guān)操作等，而代主變開關(guān)時，二次操作與一次操作配合必須緊密，否則將引起事故。
關(guān)鍵詞： 旁路開關(guān)；旁路母線充電；CT 切換；PT 非正常并列

Abstract: The 220 kV typical substation model was established. Introduction was made to the operation process, matters needing attention and common fault when the bypass switch replaced the switching of line or the main transformer high switch. The main process of bypass switch replaced line is to protect the setting value, the bypass bus charging, switch replaced operation. When the bypass switch replaced the switching of the main transformer switch, the secondary electrical operation must match up the primary electrical operation closely, otherwise faults will take place.
Key words: bypass switch; bypass bus charging; CT transforming; PT abnormal juxtaposition
