        產(chǎn)品介紹

        產(chǎn)品簡(jiǎn)介:

        CRCGIS型氣體絕緣式金屬封閉開關(guān)設(shè)備(以下簡(jiǎn)稱充氣式環(huán)網(wǎng)柜)是以低壓力SF6氣體作為絕緣和開斷介質(zhì)的50Hz三相交流戶內(nèi)高壓配電設(shè)備。環(huán)網(wǎng)柜密封箱體內(nèi)分別裝有負(fù)荷開關(guān)、負(fù)荷開關(guān)+限流熔斷器、斷路器等基本開關(guān)元件,利用負(fù)荷開關(guān)控制回路、開合負(fù)荷電流、過載電流;利用負(fù)荷開關(guān)+限流熔斷器控制、開合、隔離變壓器及其配送回路,對(duì)中壓變壓器的中壓側(cè)、變壓器及低壓配電回路內(nèi)的短路電流及過載電流進(jìn)行保護(hù),利用斷路器對(duì)設(shè)備或線路進(jìn)行保護(hù)。利用基本單元可以做成共箱式柜或基本單元拓展成為多種配電系統(tǒng)方案。共箱最多可以為六共箱,拓展型式可以無限拼接。可以根據(jù)一次主接線,將CRCGIS-12 (F) 、  CRCGIS-12 (R)、 CRCGIS-12 (V) 氣體絕緣式金屬封閉開關(guān)設(shè)備進(jìn)行組合,然后并柜使用,構(gòu)成環(huán)網(wǎng)供電回路。斷路器柜、負(fù)荷開關(guān)柜、組合電器柜也可分別單獨(dú)使用。主要用于12kV及以下的二次配電系統(tǒng),適用12kV供電線路的環(huán)網(wǎng)供電或雙輻射供電,當(dāng)某段線路發(fā)生故障時(shí),經(jīng)線路重組后使故障段隔離,可及時(shí)恢復(fù)健全線路的供電,大大提高了供電的可靠性和利用率。適用于電纜饋電網(wǎng)絡(luò)的工商業(yè)區(qū)或農(nóng)村鄉(xiāng)鎮(zhèn)的供電負(fù)荷大密度高的地區(qū)。使用安全、不受氣候影響、安裝容易、維修少,節(jié)省地方,很適合裝于箱式變電站中。
