Gaoya dianqi, 2013 为了满足电网中对252 kV罐式断路器三相机械联动的要求,需要对原LW24-252分相罐式断路器进行改进,利用原LW24-252产品的灭弧室结构,对传动部分进行改进。文中介绍了一种三相机械联动的设计方案,经测试,各项特性曲线包络线和原分相断路器进行比较,特性均相符要求,并通过型式试验验证,现已经在工程上得到应用。

Gaoya dianqi特高压直流GIL运行可靠性取决于内绝缘设计的可靠性。此外，导电元件直流电流密度的取值、弹簧触头的定位设计、GIL各元件中的绝缘件与金具连接处的楔形气隙的处理以及母线中支撑件的结构设计细节，都会对产品运行可靠性产生重大影响，不能忽视。对于运行环境十分严酷的UHV DC GIL为保证内绝缘工作可靠性和减少气体维护工作量，文中还提出了高气密性结构设计。为适应-50 ℃低温运行要求，产品选用了液化温度很低的N2/SF6混合气体，对两种气体的配比，压力特性和绝缘特性进行了讨论与计算。还有产品的局放 ...
