Aimed at the short circuit current of 35kV bus is too large,it impacts the steady operation,some measurements are taken to restrict short circuit current,such as installing current-limit reactor on the preliminary equipment,mirocomputer differential bus protection on the secondary protection or adding a time-delay quick-break protection on the side of upper transformer.
针对35kV母线短路电流过大,影响母线安全运行的情况,在一次设备上采取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。
