地震作用下断路器动力时程分析及阻尼效应研究

Gaoya dianqi, 2010
结合我国现行电力设施抗震设计规范（GB50260—96）、高压开关抗震试验标准（GB/T13549—92）及国际标准（IEEEStd693—2005）,对电气设备的抗震分析与设计进行了讨论,提出了有关电气设备抗震设计中的一些关键问题,比如说动力时程分析中的地震动输入、支架动力放大系数、抗震设防等级等。首先采用ANSYS软件,以一220kV瓷柱型SF6断路器为研究对象,建立其有限元模型,开展了三类地震输入下的动力时程分析,详细介绍了电气设备动力时程分析方法。并通过对断路器关键节点和部位的位移 ...

SF₆电气设备分解产物在线监测方法研究

Gaoya dianqi, 2014
目前判断SF6电气设备故障的方法大都是对其分解产物进行离线检测,难以尽早地发现设备内部的潜在故障。笔者通过分析SF6电气设备内部故障时分解产物的产生规律和特点,研制了一套基于实时检测SO2的SF6电气设备状态监测系统,在介绍了该系统的设计原理和设计方案的基础上,详细阐述了在系统设计过程中所采用的关键技术,首次实现了SO2电化学传感器在SF6电气设备在线监测中的应用,设计了流动气体取样结构,提高了SO2监测的准确度,提出查询波峰波谷算法计算SO2体积分数的变化速率 ...
