    產品介紹

    產品簡介:

    CRCGIS型氣體絕緣式金屬封閉開關設備(以下簡稱充氣式環(huán)網柜)是以低壓力SF6氣體作為絕緣和開斷介質的50Hz三相交流戶內高壓配電設備。環(huán)網柜密封箱體內分別裝有負荷開關、負荷開關+限流熔斷器、斷路器等基本開關元件,利用負荷開關控制回路、開合負荷電流、過載電流;利用負荷開關+限流熔斷器控制、開合、隔離變壓器及其配送回路,對中壓變壓器的中壓側、變壓器及低壓配電回路內的短路電流及過載電流進行保護,利用斷路器對設備或線路進行保護。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設備進行組合,然后并柜使用,構成環(huán)網供電回路。斷路器柜、負荷開關柜、組合電器柜也可分別單獨使用。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)網供電或雙輻射供電,當某段線路發(fā)生故障時,經線路重組后使故障段隔離,可及時恢復健全線路的供電,大大提高了供電的可靠性和利用率。適用于電纜饋電網絡的工商業(yè)區(qū)或農村鄉(xiāng)鎮(zhèn)的供電負荷大密度高的地區(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。

    產品特點:

    1.小型化、全封閉、全絕緣、防凝露、抗污穢、高絕緣

    2.壽命長:負荷開關10000次,斷路器20000次。

    3.適合高海拔:4000米

    4。適合低溫度:-45度

    5.容量大:斷路器柜額定電流1250A,開斷電流31.5KA
