可靠的壓力表KONICS/KINS,IGP10制造廠家授權(quán) 圖中我用青色框標(biāo)明的區(qū)域就是斷路器,當(dāng)然,這臺(tái)斷路器是低壓配電室里面用的。而用粉色框框起來(lái)的部分與題主的問(wèn)題有關(guān)。注意看這臺(tái)斷路器,我們發(fā)現(xiàn)它是四極的,而且在三條相線中,半圓的標(biāo)識(shí)和半個(gè)正方形的標(biāo)識(shí)標(biāo)識(shí)這臺(tái)斷路器具有過(guò)載保護(hù)和短路保護(hù)功能。
這是利用電磁感應(yīng)的原理,以及楞次定律的運(yùn)行方式。電流互感器的工作必須保證額定電流,比如二次側(cè)為5A,長(zhǎng)時(shí)間超額工作,會(huì)導(dǎo)致較大的誤差,儀表無(wú)法顯示準(zhǔn)確的數(shù)據(jù),并且可能會(huì)引起絕緣老化,燒壞內(nèi)部繞組。電壓互感器的運(yùn)行是允許超額工作的,不過(guò)不能超過(guò)額定值的10%,其作用是利用電磁感應(yīng)原理改變電壓幅值,由于二次側(cè)不允許發(fā)生短路,因此電壓互感器又被稱為儀用變壓器。
