電能(neng)質(zhi)量的標準(zhun)是什麽(me)？

目(mu)前我(wo)國(guo)組(zu)織(zhi)制(zhi)定(ding)電(dian)能質(zhi)量標準(zhun)的單位(wei)是：全國(guo)電(dian)壓(ya)電(dian)流等級(ji)和頻(pin)率標準(zhun)化(hua)技(ji)術委員(yuan)會(hui)(TC1)和全國(guo)電(dian)磁兼(jian)容(rong)標(biao)準(zhun)化(hua)技(ji)術委員(yuan)會(hui)(TC246)。 TC1制定(ding)的標準(zhun)及其主要指(zhi)標(biao)：  

(1) GB12325-1990供電電壓(ya)允(yun)許偏差:35KV及以上(shang)正(zheng)、負(fu)偏差的值之和小(xiao)於(yu)10%;10KV及以下(xia)小於(yu)±7%;220V小(xiao)於(yu)+7%、-10%  

(2) GB/T15945-1995電(dian)力系(xi)統(tong)頻(pin)率(lv)允許偏差:允許偏差±0.2?HZ;系(xi)統(tong)較(jiao)小(xiao)±0.5?HZ

(3)GB/T15543-1995三(san)相(xiang)電(dian)壓(ya)允(yun)許不平衡(heng)度:三(san)相(xiang)電(dian)壓(ya)允(yun)許不平衡(heng)度為2%、短(duan)時(shi)不(bu)超過(guo)4%;用(yong)戶(hu)引起不(bu)平(ping)衡(heng)度為1.3%  

(4)GB12326-1990電壓(ya)允(yun)許波(bo)動(dong)和閃(shan)變:電(dian)壓(ya)允(yun)許波(bo)動(dong):小於(yu)10KV 2.5%;35～110KV 2%；大(da)於(yu)220KV 1.6%     閃(shan)變：要(yao)求(qiu)較(jiao)高0.4%【FS：PAGE】；壹(yi)般(ban)0.6%

(5)GB/T14549-1993公用(yong)電(dian)網(wang)諧波(bo)：電(dian)網(wang)諧波(bo)電(dian)壓(ya)限(xian)值；電網(wang)電壓(ya)/KV  0.386、1035、66110；畸變率/% 5.04.03.02.0（該(gai)標準(zhun)就(jiu)用(yong)戶(hu)向電網(wang)註入(ru)諧波(bo)電(dian)流限(xian)值也作(zuo)了規(gui)定(ding)。）  

(6)GB/T18481-2001暫(zan)時(shi)過(guo)電壓(ya)和瞬(shun)態(tai)過(guo)電壓(ya)：標(biao)準(zhun)規(gui)定(ding)了(le)交(jiao)流電力系(xi)統(tong)中(zhong)作(zuo)用(yong)於(yu)電(dian)氣設備的暫(zan)時(shi)過(guo)電壓(ya)和瞬(shun)態(tai)過(guo)電壓(ya)要(yao)求、電氣設備的絕緣(yuan)水(shui)平，以及過(guo)電壓(ya)保(bao)護(hu)方法。其中(zhong)暫(zan)時(shi)過(guo)電壓(ya)包(bao)括(kuo)工頻過(guo)電壓(ya)和諧(xie)振過(guo)電壓(ya)；瞬(shun)態(tai)過(guo)電壓(ya)包(bao)括(kuo)操作(zuo)過(guo)電壓(ya)和雷電(dian)過(guo)電壓(ya)。
