電容器組的放電線圈放電線圈有什么用？難道就是個(gè)PT嗎？一放電線圈定義、型號(hào)定義：當(dāng)電容器從電源脫開后能將電容器端子上的電壓在規(guī)定時(shí)間內(nèi)降到規(guī)定值的帶有繞組的器件。放電線圈分為油浸式和干式兩類。放電性能要求：放電起始至5s內(nèi)，將電容器的剩余電壓自額定值下降到50V以內(nèi)。干式戶內(nèi)型放電線圈戶外油浸式放電線圈二放電線圈與電壓互感器區(qū)別相同點(diǎn)：1)都是利用電磁感應(yīng)原理制成的;2)主要工作物質(zhì)都是銅和鐵，即線圈和硅鋼片鐵心;3)所用的絕緣介質(zhì)種類，都是變壓器油、氣體、固體，絕緣介質(zhì)只對(duì)帶電體起隔離絕緣作用。不同點(diǎn)：（1）電壓互感器是互感器的一種，一般有多個(gè)二次繞組，容量、精度各不相同，分別用于計(jì)量、測(cè)量和保護(hù)。（2）高壓并聯(lián)電容器組所配用的單相放電線圈，與高壓并聯(lián)電容器組并聯(lián)連接，使電容器從電力系統(tǒng)切除后的剩余電荷能夠快速泄放，使電容器的剩余電壓在規(guī)定時(shí)間內(nèi)達(dá)到要求值。當(dāng)放電線圈有二次繞組時(shí)，還可用于提供電容器組開口三角形電壓不平衡器保護(hù)。（3）電壓互感器線與地的額定一次電壓為該系統(tǒng)標(biāo)稱電壓的1/√3倍。而一般情況下，放電線圈的額定一次電壓為與其并聯(lián)電容器的額定電壓。。</p><p>
