GIS设备中电能计量装置改造方法的探讨

Study on transformation means for electric energy metering devices in gas insulated switchgear

针对目前GIS内装电能计量装置普遍存在准确度等级过低的问题,探讨出一套效果好、费用低廉的改造方法,该方法对非GIS电能计量装置存在的问题也同样具有改造效果。这些方法在实际使用中证明是切实可行的。

Aiming at the ubiquitous problem of excessively low accuracy class of electric energy metering devices in gas insulated switchgear （GIS）, effective and economical altering approaches are studied, which are also applicable to non-GIS electric energy metering devices. The feasibility of these approaches has been proved in practice.
