Gaoya dianqi, 1993 JK140型高压开关参数自动检测仪是一种新型检测仪器,是一种高精度、易操作、显示直观、适用范围广的自动化检测装置。可实时、准确地检测多种高压开关的分合闸速度、时间、行程（总行程、超行程、开距）、不同期性等多种参数,并能自动打印数据及开关触头的运动特性曲线。仅需一人操作,即可获取28种参数、60余个数据。 JK140型高压开关参数自动检测仪突破了传统检测装置只能测量高压开关小行程平均速度的局限,解决了开关触头运动瞬间速度（即加速度运动过程）的检测问题。它适用于高压开关的检测维修、安装调试与研制开发。

Gaoya dianqi, 2017 电网的发展对高压开关产品的可靠性提出更高的要求。SF6气体泄漏是导致高压开关缺陷和故障最重要的因素之一,以某省110 kV断路器SF6气体泄漏运行数据为基础,研究了高压开关产品的可靠性数据分析方法。对运行数据的统计分析结果表明,SF6气体泄漏数据能够用威布尔分布模型进行分析描述。进一步对威布尔分布的参数进行了参数估计,并将参数估计结果与统计直方图进行对比,证明了参数估计结果的有效性。基于此,最后对高压开关产品SF6气体泄漏的寿命情况进行了分析,并给出了针对高压开关产品密封结构的基本运维策略。
