摘要

机械式SF6密度控制器在运行中时有误报警现象。对国内外已使用过的4类SF6密度控制器的不同结构、SF6温度、环温以及使用处海拔高度对监控特性的影响进行了分析。得出

Ⅳ型国产密度控制器质量稳定、监控精度较好;目前使用的SF6密度控制器对GCB/GIS的SF6密度具有一定的监控作用

但不能避免开关运行时出现的SF6密度示数"假高"现象

为消除密度示数"假高"、对环境温度的欠补偿和海拔影响

根本出路是开发新型智能化的SF6密度控制器。

Abstract

Four types of existing mechanical SF6 density controllers are analyzed to understand their structures

SF6 temperature

part temperature

and altitude influences on monitoring characteristics.It is found that the Ⅳ-type SF6 density controller made in China possesses stable quality and high monitoring accuracy;the SF6 density controller in use has certain monitoring function for the SF6 density in GCB/GIS

but the "false high readings" of SF6 density can not be avoided during switching operation.In order to eliminate the "false high readings" phenomenon

under compensation for environmental temperature

and the influence of altitude

it is necessary to develop a new intelligent SF6 density controller.
