The thesis mainly concerns the following aspects: the relay protection and its trip-close circuit of two circuits transmission-lines are stand alone. The device has the ability of phase-trip that is owns transmission line single phase , 2 or 3phases fault only fault phase tripped.so as to making the power system contact as close as possible. The function of reclosing distribute into relay protection of line and breaker, so it is easy to get no-serious fault information of line protection and realize self-adapted multi pole reclosing. The breaker reclosing depend on the state of owns breaker andthe adjacent breaker. The criterion of serious fault and the sequence reclosing is simple and useful.
