田湾核电站3&4号机组环行起重机结构及性能特点

Structure and Performance of Polar Crane in Tianwan Nuclear Power Plant

文章介绍了田湾核电站3&4号机组核岛厂房环行起重机(简称环吊)的结构组成,针对起升机构行星减速器、钢丝绳交叉缠绕结构等田湾核电站环吊的主要特点与特殊性能,进行了功能分析,实现了单一故障保护系统,对后续其他堆型的环吊设计具有一定的参考价值,对其他厂房起重设备结构和安全性设计也具有一定的指导意义。

This paper introduced and analyzed the structure, performance requirement and control system of polar crane of unit 3＆4 in Tianwan Nuclear Power Plant. And it also illustrated that how the single fault protection system works. It has a certain reference for the design of other cranes.
