摘　　要：针对35kV母线短路电流过大,影响到母线安全运行的情况,采取在一次设备上加装限流电抗器的办法来限制母线短路电流,在二次保护上加装微机母差保护或在上级变压器35kV侧新增一段限时速断保护,以较短时间切除母线故障。Aiming at the condition of large short circuit influencing the 35 kV bus-bar safe operation, takes the methods of installing current limiting reactor on the primiary equipment to limit the short circuit current of bus-bar, installes processor bur-bar differential protective device on the secondary protective device or installes a time limit quick break protective device on the high level transformer 35 kV side, removes the bus-bar failure in short time.
