It has both open circuit and close circuit instructions.

它不僅具有開環(huán)指令精品日韩手机版视频在线观看免费，還具有閉環(huán)指令亚洲欧美另类校园。

The primary circuit is a close circuit that pressurize water whose function is to extract heat from the nuclear reactor.

主回路是一個(gè)對冷卻劑加壓的封閉回路欧美潮喷十大喷潮。冷卻劑的作用是帶出反應(yīng)堆內(nèi)的熱量日韩特黄Av毛片免费播放。

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.
