SF_6泄漏类缺陷无线监测与预警装置

Wireless Monitoring and Early Warning Devices for SF_6 Leakage Defect

针对常规变电站或发电厂中已发生过SF_6漏气缺陷的设备,研制SF_6泄漏类缺陷无线监测与预警装置,通过设置指定压力值、漏气速率两种报警方式,提前对SF_6设备的压力降低现象进行预警。同时,可向装置征询当时SF_6压力值,实时掌握SF_6设备压力,提高对已出现报警的设备"可控在控"能力。本文描述了装置原理与结构,重点包括装置的整体设计与制造工艺,元器件的技术参数与应用安全性等。通过制作针对不同SF_6设备的对接接头,实现在不同电压等级、不同类型SF_6设备上直接带压安装使用,安全可靠。

For the equipment which has SF6 gas leakage defect in the in plant station, wireless monitoring and early warning devices for SF6 leakage defect were developed, and the early warning for reducing of SF6 equipment pressure was developed in by setting the specified pressure value and air leakage rate. At the same time, through consulting SF6 pressure value in the device, the ability of controlling the device which had given alarm increased. In this paper the principle and structure were described, mainly including the overall design and manufacturing technology of the devices, technical parameters and application safety of components and so on. By making butt joints of different SF6 equipment, directly installing and using with voltage on SF6 devices with different voltage grades and different types were realized, and it was safe and/reliable.
