在潮汐河口支流口门上建闸，其闸下淤积面貌主要取决于干流主槽的位置，这与在潮汐河口干流上建闸的闸下淤积问题有着本质上的差异。

The thyristor and stator winding have different topology architecture when the inductionmotor is controlled by the thyristor. Based on the fault characteristics of the inductionmotor, the current through the thyristor and the stator winding are studied when theshort-circuit or open-phase fault is occurred. The reasonable protection method based onthe different topology architecture is given in the thesis, and the induction motor and theover-current of the thyristor are reliably protected.

在分析异步电动机一般故障特性的基础上，针对采用晶闸管对异步电动机进行节能控制时晶闸管与异步电动机绕组所形成的不同拓扑结构，详细分析了在发生短路、断相等各种故障时晶闸管与异步电动机绕组中通过的电流，为实现晶闸管的过流速断和异步电动机的可靠保护提供合理的保护判据。

本文设计了基于电力系统继电保护的微机综合自动重合闸，包括综合重合闸的工作原理、综合重合闸的构成、重合闸与继电保护的配合，装置的硬件部分设计及软件部分设计。

Composed of round door frames, gate, rack , sealing strip, adjustable structure of sealing , this kind of sealing principle is door frame is fixed on square pipe of pool and wall, rack is fixed on door frame and wall, through rack opens and closes till weld block of gate meets with weld block of rack to make sealing surface of gate close to sealing surface of door frame to achieve sealing .Besides , sealing of gate and sealing of door frame are made of inlaid copper which is well resistance ,It makes valve with well sealing ,wear resistance , corrosion resistance, easily operation, convenient installation , long life , wildly usage.

本闸门是由圆型门框、闸板、导轨、密封条、可调整密封机构等部件组成，其密封原理是门框固定于水池圆型管道及墙壁上，导轨固定门框与墙壁上，闸板通过导轨做启闭动作，直到闸板上的锲块碰到导轨条上的锲块，使得闸门密封面紧靠门框上的密封面，从而起到密封效果，另外闸板密封面跟门框密封面都是镶铜材质的，具有耐磨损的特性，使得阀门密封密封性好、耐磨性强、耐腐蚀、操作简单、安装方便、使用寿命长、适应性广等特点。
