    HH15(QSA)隔離開(kāi)關(guān)熔斷器組

    HH15(QSA)系列隔離開(kāi)關(guān)熔斷器組主要用于有高短路電流的配電  電路和電動(dòng)機(jī)電路中,作為手動(dòng)頻繁操作的開(kāi)關(guān)、隔離開(kāi)關(guān)和應(yīng)急開(kāi)  關(guān),并作電路保護(hù)之用。開(kāi)關(guān)可直接開(kāi)閉電動(dòng)機(jī)等高電感負(fù)載,特別適  用于抽屜式開(kāi)關(guān)柜成套裝置中使用。

    本系列開(kāi)關(guān)由刀型靜觸頭、滾動(dòng)動(dòng)觸頭及滅弧裝置組成的接觸系統(tǒng)均組裝在由耐弧工程塑料制成的封閉底座內(nèi),能達(dá)到零飛弧。操作機(jī)構(gòu)由具有彈簧儲(chǔ)能的連桿傳動(dòng)機(jī)構(gòu)構(gòu)成,靠彈簧力完成開(kāi)關(guān)的分、合,使開(kāi)關(guān)動(dòng)作無(wú)關(guān)人力操作。手柄由操作手柄和傳動(dòng)軸等構(gòu)成,屬旋轉(zhuǎn)操作方式。當(dāng)手柄旋轉(zhuǎn)操作時(shí),使操作機(jī)構(gòu)彈簧儲(chǔ)能,靠?jī)?chǔ)能的彈簧力釋放帶動(dòng)動(dòng)觸頭與靜觸頭形成合、分兩種狀態(tài),從而達(dá)到開(kāi)關(guān)分合主電路的目的。

    本開(kāi)關(guān)的上部可裝一個(gè)或二個(gè)輔助開(kāi)關(guān),每個(gè)輔助開(kāi)關(guān)有一對(duì)電器上分開(kāi)的常開(kāi)觸頭和常閉觸頭,能使控制回路明確指示開(kāi)關(guān)主電路的通斷情況。

    當(dāng)開(kāi)關(guān)處于斷開(kāi)位置時(shí),其外露導(dǎo)電部件均不帶電,確保維修和更換熔斷體的安全性。


    Series HH15 (QSA) Switch-disconnector-fuse integrates the functions of load Rate  switch and fuse short-circuit protection. It is mainly applied in distribution of high
    short-circuits and motor circuits as the power switches and emergency  switches.  It is especially suitable for installation and application in draw type  cabinets. This series switches are of closed structure design. The contact  system is composed of static knife contacts. moving rolling contacts and an quenching sets that are all fitted in the sealed case made of arc resistant
    engineering plastic and zero arc flash out is achieved. The switching machanism is of reliable spring energy stored independent manual operation style.  On the upper part of the switch utmost two auxiliary switches may be quipped  in,each having a set of electrical separated normal open and normal closed  contacts.
