摘　　要：目前,计量工作包括大用户高供高计电能表、小水电站电能表、所辖电网关口计量点电能表、变电站平衡表的装接、轮换、现场校验、故障处理、现场故障分析等内容。在现场校验工作中,对现场校验仪的使用十分频繁。但是,当前的现场校验仪的接线烦琐复杂且需要很多的辅助工具。同时,现场高压大用户的计量屏高低不一,型号各异,给现场校验工作带来了很大困难。本文重点对大用户电能表现场校验存在的问题进行分析,并有针对性地提出解决措施,缩短现场校验时间,提高计量工作效率。At present,the measurement work includes the installation,rotation,on-site calibration,fault treatment and on-site fault analysis of high-power meter for large users,energy meter for small hydropower stations,energy meter for measuring points at the gateway of the power grid under their jurisdiction,and balance meter for substations. Field calibrators are frequently used in field calibration work,but the wiring of existing field calibrators is complex and needs many auxiliary tools.At the same time,the measurement screens of large high-voltage users vary in height and type,which brings great difficulties to the field verification work.This paper focused on the analysis of the existing problems in the field calibration of large-scale users'electric energy performance,and put forward corresponding measures to shorten the field calibration time and improve the efficiency of measurement work.
