描述
另外需要注意的有,由于目前電子表的機(jī)械計(jì)量器,還沒有從原理上根本解決卡字問題。主要是通過選擇制造工藝好的計(jì)量器和進(jìn)廠時(shí)嚴(yán)格篩選保證電能表整機(jī)質(zhì)量。因此,要特別注意計(jì)量器的質(zhì)量。步進(jìn)電機(jī)有屏蔽可以防電磁干擾,外殼采用鋁合金支架、齒輪精細(xì)、無毛刺、材料不易變形、有自潤(rùn)滑性能、步進(jìn)電機(jī)磁性能強(qiáng)、加工精密,都可以減少卡字的問題。要注意仔細(xì)檢查和了解。再就是要進(jìn)行走字檢驗(yàn)。為更嚴(yán)格地考核計(jì)量器質(zhì)量,保證安裝到現(xiàn)場(chǎng)的電能表在電壓允許范圍內(nèi)都能正確計(jì)量,建議采用本地區(qū)電網(wǎng)可能出現(xiàn)的最低(不考慮暫態(tài))電壓進(jìn)行走字試驗(yàn)。
