查询词典 to a fault

Hechi-Yishan fault zone is located in the north of Guizhong depression, which general strike is NW-EW and consists of a series of obduction fault. Generally, there are two main faults, the fault-fold belt about 5-20km is made of main faults, subsidiary faults and concomitant folds; The dip of main faults is N or S; It can be divided into four different structural sections along its strike (Hechi section, Yishan section, Liucheng section and Yingshan section). There are some differences among these sections in structure characteristic, such as fault structure, associated structure, fold association style, deformation of rock, and so on.

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.
