熱銷美國(guó)UE真空開(kāi)關(guān)J400系列全現(xiàn)貨供應(yīng)

美國(guó)UE真空開(kāi)關(guān)為純機(jī)械形變導(dǎo)致微動(dòng)開(kāi)關(guān)動(dòng)作。當(dāng)壓力增加時(shí)，真空開(kāi)關(guān)作用在不同的傳感壓力元器件（膜片、波紋管、活塞）產(chǎn)生形變，將向上移動(dòng)，通過(guò)欄桿彈簧等機(jī)械結(jié)構(gòu)，zui終啟動(dòng)zui上端的微動(dòng)開(kāi)關(guān)，使電信號(hào)輸出。機(jī)械壓力開(kāi)關(guān)設(shè)定方式從功能原理上均為連續(xù)位移型，設(shè)定點(diǎn)可單點(diǎn)設(shè)定并zui多可達(dá)到3個(gè)不同的設(shè)定點(diǎn)。

美國(guó)UE真空開(kāi)關(guān)是控制管路或某封閉空間的真空度的開(kāi)關(guān)，為純機(jī)械形變導(dǎo)致微動(dòng)開(kāi)關(guān)動(dòng)作。

美國(guó)UE真空開(kāi)關(guān)是框架式斷路器的通俗稱呼，實(shí)際上就是斷路器，主要作用是切斷大電流的電器元件。

美國(guó)UE真空開(kāi)關(guān)有負(fù)壓及正負(fù)壓兼顧的不同量程段的多種選擇。在測(cè)負(fù)壓的同時(shí)，UE真空開(kāi)關(guān)可以耐受一定強(qiáng)度的正壓，在電力行業(yè)有極廣泛的應(yīng)用。
