2.按用途可分為：（1）低壓控制電器--主要在低壓配電系統(tǒng)及動力設備中起控制作用，如刀開關、低壓斷路器等。（2）低壓保護電器--主要在低壓配電系統(tǒng)及動力設備中起保護作用，如熔斷器、熱繼電器等。 3.按種類可分為：刀開關、刀形轉(zhuǎn)換開關、熔斷器、低壓斷路器、接觸器、繼電器、主令電器和自動開關等。</p><div

style="text-indent:25px">儀器儀表是用以檢出、測量、觀察、計算各種物理量、物質(zhì)成分、物性參數(shù)等的器具或設備。真空檢漏儀、壓力表、測長儀、顯微鏡、乘法器等均屬于儀器儀表。近年來，得益于機械、冶金、石化行業(yè)等儀器儀表服務領域經(jīng)營狀況的好轉(zhuǎn)，我國儀器儀表制造業(yè)發(fā)展一路向好。一些中低檔產(chǎn)品已具有規(guī)模優(yōu)勢和國際市場競爭力。中國已成為[ "耐磨熱電偶", "氣體檢測儀器", "便攜式氣體報警控制器", "雙金屬溫度計" ]等產(chǎn)品的生產(chǎn)和出口大國，其他儀器設備等產(chǎn)品的出口也開始取得突破。在國民經(jīng)濟運行中，研發(fā)、銷售計算機軟硬件;計算機系統(tǒng)集成;銷售電子產(chǎn)品、儀器儀表、電氣設備、機械設備、閥門、水泵、電線電纜、通訊器材(不含無線廣播電視發(fā)射及衛(wèi)星地面接收設備)、醫(yī)療器械(***一類)、實驗設備、化工產(chǎn)品(不含危險化學品)、五金交電、照明設備。等設備是提高勞動生產(chǎn)率的倍增器，對國民經(jīng)濟有著巨大的輻射作用和影響力。美國商業(yè)部國家技術和標準研究院（NIST）提出的報告稱：美國90年代儀器儀表工業(yè)產(chǎn)值只占工業(yè)總產(chǎn)值的4%，但它對國民經(jīng)濟（GNP）的影響面卻達到66%。從銷售廣義角度來說，儀器儀表也可具有自動控制、報警、信號傳遞和數(shù)據(jù)處理等功能，例如用于工業(yè)生產(chǎn)過程自動控制中的氣動調(diào)節(jié)儀表，和電動調(diào)節(jié)儀表，以及集散型儀表控制系統(tǒng)也皆屬于儀器儀表。南充高低壓電器推薦</p><p
