一起來(lái)了解下速斷真空斷路器的結構特點(diǎn)
更新時(shí)間:2021-03-31   點(diǎn)擊次數:2462次
        ZW32-12FG/630-20真空斷路器為額定電壓12KV,三相交流50HZ的戶(hù)外配電設備。主要用于開(kāi)斷、關(guān)合電力系統中的負荷電流、過(guò)載電流及短路電流。適用于變電站及工礦企業(yè)配電系統中作保護和控制之用,及農村電網(wǎng)頻繁操作的場(chǎng)所。
真空斷路器引用標準斷路器符合《GB/T11022高壓開(kāi)關(guān)及其控制設備標準的公用技術(shù)條件》、《GB1984-89交流斷路器》《GB1985-89交流高壓隔離開(kāi)關(guān)盒接地開(kāi)關(guān)》和DL404、IEC56等標準的有關(guān)要求。
結構特點(diǎn):
1.裝有真空來(lái)弧室的高壓真空斷路器開(kāi)斷性能穩定可靠,具有無(wú)燃燒和爆炸危險、安全、免維護、體積小、重量輕(<100kg)和使用壽命長(cháng)等特點(diǎn)。
2.操作機構新穎、簡(jiǎn)單、動(dòng)作可靠、體積小、機械壽命可達1萬(wàn)次。
3.該斷路器由三相支柱、機構箱組成,結構簡(jiǎn)單明了,三相支柱及電流互感器采用戶(hù)外環(huán)氧樹(shù)固體或硅橡膠絕緣,具有耐高低溫、耐紫外線(xiàn)、耐老化等優(yōu)點(diǎn);采用小型化彈簧操動(dòng)機構,分合閘能耗低、機構傳動(dòng)輸出采用主軸滑動(dòng)方式,無(wú)扭力耗損,分合傳動(dòng)件少,可靠性高;電流互感器安裝于動(dòng)端出線(xiàn),二次采用插拔結構,維護更換方便。
4.斷路器采用全封閉結構,密封性能好,有防潮、放凝露性能,適應于高溫潮濕地區使用。
5.斷路器的安裝方式可采用單桿或雙桿座裝方式。
