NH40系列負(fù)荷隔離開(kāi)關(guān)
NH40系列負(fù)荷隔離開(kāi)關(guān)(以下簡(jiǎn)稱開(kāi)關(guān))是我公司引進(jìn)歐洲先進(jìn)技術(shù)研制而成，該產(chǎn)品具有國(guó)際九十年代末期水平,是國(guó)內(nèi)同類產(chǎn)品中理想的更新?lián)Q代產(chǎn)品。開(kāi)關(guān)廣泛適用于建筑、電力、石油化工及其它行業(yè)的配電系統(tǒng)和自動(dòng)化系統(tǒng)。
模塊化設(shè)計(jì)結(jié)構(gòu)，具有靈活多樣的組合性，采用玻璃纖維增強(qiáng)不飽合聚脂樹脂制造外殼，有很高的介電性能，防護(hù)能力和可靠的操作**性。操作機(jī)構(gòu)是彈簧蓄能、瞬時(shí)釋放的加速機(jī)構(gòu)瞬時(shí)接通與分?jǐn)嚯p斷點(diǎn)觸頭結(jié)構(gòu)。與操作手柄的速度無(wú)關(guān)，極大提高了各項(xiàng)電氣性能與機(jī)械性能。
多種結(jié)構(gòu)與操作方式，有直接觀察觸頭通斷狀態(tài)的窗口，有柜內(nèi)、柜外操作，有正面、側(cè)面操作，有板后接線。開(kāi)關(guān)造型美觀、新穎、簡(jiǎn)潔、體積小功能全，是同類產(chǎn)品中理想的選擇。
產(chǎn)品特點(diǎn)：彈簧蓄能瞬時(shí)釋放時(shí)加速機(jī)構(gòu)實(shí)現(xiàn)了快速接通與分?jǐn)啵?3.8米/秒），與操作手枘速度無(wú)關(guān)、極大提高了熄滅電弧能力。由玻璃纖維增強(qiáng)不飽和聚脂樹脂制造的外殼具有良好的阻燃性能、介電性能、抗碳化性和抗沖擊性。并聯(lián)雙斷點(diǎn)觸頭具有自潔作用。所有觸頭材料是銅鍍銀合金，具有兩個(gè)分離觸頭面。隔離距離大。在“0”位時(shí)，可同時(shí)用三把鎖鎖住手柄，可靠避免誤操作。
產(chǎn)品用途:NH40系列負(fù)荷隔離開(kāi)關(guān)主要用于交流50Hz，額定電壓660V，直流額定電壓440V，額定電流至4000A。用于不頻繁接通與分?jǐn)嚯娐放c線路的隔離之用。
