    產(chǎn)品介紹

    1 范圍:
    配DZ47分勵脫扣器 MX+OF,主要適用于交流50HZ(或60HZ),額定電壓至400V的線路中與DZ47小型斷路器或多極斷路器配裝做遠(yuǎn)距離操作,指示斷路器通斷狀態(tài)。
    2 正常工作條件和安裝條件:
    周圍空氣溫度為:-5℃~+40℃,24小時內(nèi)其平均值不超過+35℃。
    海拔高度:不超過2000M。
    大氣條件:安裝地點的空氣相對濕度在最高溫度為+40℃時不超過50%;
    在較低的溫度下可允許有較高相對濕度,最濕月的月平均最低溫度不超過+25℃,該月的月平均最大相對濕度不超過90%,并考慮到因溫度變化發(fā)生在產(chǎn)品表面上的凝露。
    污染等級:為污染等級2。
    安裝類別:為安裝類別Ⅱ Ⅲ。
    3 基本參數(shù)及技術(shù)性能:
    基本參數(shù)
    a:額定絕緣電壓(UI):500V
    b:額定控制電源電壓(US):AC:230,400V.
    主要性能指標(biāo) 動作特性:
    a: 在額定控制電源電壓值的70%~110%,脫扣器均應(yīng)可靠動作使斷路器斷開。
    b:觸頭分?jǐn)嗄芰?nbsp;AC:3A/400V;6A/230V;
    c:壽命 脫扣器操作壽命不低于0.4萬次。
    4 主要工作原理:
    脫扣器主要由手柄,脫扣機(jī)構(gòu),電磁系統(tǒng),指示件,外殼等零件組成。當(dāng)脫扣器未合閘時,常閉輔助觸頭接通,外接安全信號燈亮,當(dāng)配裝斷路器合閘,并帶動脫扣器合閘時,脫扣器常閉輔助觸頭斷開,常開輔助觸頭接通,外接警告信號燈亮;當(dāng)接按鈕接通時,脫扣器電磁系統(tǒng)吸合,使脫扣機(jī)構(gòu)動作,從而帶動配裝斷路器脫扣分?jǐn)噙_(dá)到分勵脫扣目的,與此同時,脫扣器指示件動作顯示脫扣標(biāo)記,脫扣器常開觸頭分?jǐn)啵i]接通,外接信號指示轉(zhuǎn)換。
    5 安裝使用及維修:
    安裝使用安裝前先檢查脫扣器與所使用的正常工作條件是否相符。 維修 脫扣器在保修期限內(nèi),如發(fā)現(xiàn)問題可找分銷商進(jìn)行聯(lián)系。
