| Abstract: | PT anti-inverse charge is always happen in power system.The detail process and causes of a 220 kV bus PT anti-inverse charge incident at a 500 kV substation were analyzed in the paper.Then three types switch relays principles were described using circuit figures,and the differences of requirements in the complexity of loop,the reliability of auxiliary contacts and the performance of relay reset coil were compared.Combining their advantages,an single-position self-maintaining switch approach was proposed.Stu... |
