随着电网的高速发展5,00kV系统主网架已经基本成型,在电网的规模化建设中,可靠性与经济性的地位越发重要。一般敞开式设备为了节约成本,均采用配置开关单侧流变的方式,该方式在简化设计、节约成本的同时,也存在着问题,即死区。死区范围很小,容易被忽视,但危害性却很大。本文从死区的成因谈起,介绍死区的危害,并结合现场实际探讨死区的应对措施。

With rapid development of power grid,500kV system main grid has basically taken shape,reliability and economy are more and more emphasized in grid scale construction.In order to save costs,open type devices use the switch unilateral rheology generally.This mode simplifies design and saves costs,meanwhile,there is still a problem,dead zoon.The range of dead zoon is very small,easily overlooked,but the harm is great.The paper discusses the causes of dead zoon,harm and the precautions combining with the reality.
