静止无功补偿器(STATCOM)水冷系统一次检修的探讨

The Discussion about Water Cooling System of Static Synchronous Compensator (STATCOM)

摘要: 密闭式循环水冷系统是静止同步补偿器(STATCOM)设备重要组成部分，对于检修工种来说是一种新设备。本文对此冷却方式进行了探讨，介绍了密闭水冷系统的组成结构、特征和冷却水路结构方式；分析了水冷系统的主要故障表现、处理方法和具体处理步骤；探讨了水冷系统的检修专业年度检查策略，力求防止由于对新设备检修经验较少，而造成STATCOM设备故障或停运，提高运行可靠性。

Abstract: The closed circulating water cooling system is an important part of Static Synchronous Compen-sator (STATCOM), and it is new equipment for maintenance workers. The cooling method is dis-cussed in this paper. In addition, the composition, structure and characteristics of closed water cooling system and the structure of cooling water way are introduced. Besides, the main fault performance, treatment method and specific processing steps of water cooling system are analyzed. Furthermore, the annual inspection strategy of water cooling system maintenance specialty is discussed. These are to avoid the STATCOM equipment failure or outage due to less experience in the maintenance of new equipment, and improve operational reliability.
