style="text-indent:25px">成套設(shè)備是指生產(chǎn)成品或半成品的工業(yè)聯(lián)合裝置。它可以是一個(gè)工段、一條生產(chǎn)線、一個(gè)車間或一個(gè)工廠?？梢允悄骋粚I(yè)的單項(xiàng)設(shè)備，也可以是數(shù)個(gè)專業(yè)的綜合設(shè)備。高低壓：按照中華人民共和國(guó)行業(yè)標(biāo)準(zhǔn)DL 408—91《電業(yè)安全工作規(guī)程》第1.4的規(guī)定，電氣設(shè)備分為高壓和低壓兩種。高壓：設(shè)備對(duì)地電壓在250V以上者：低壓：設(shè)備對(duì)地電壓在250V及以下者。高低壓成套設(shè)備就是包含有高壓設(shè)備和低壓設(shè)備的綜合設(shè)備。低壓電器一般都有兩個(gè)基本部分：一個(gè)是感測(cè)部分，它感測(cè)外界的信號(hào)，作出有規(guī)律的反應(yīng)，在自控電器中，感測(cè)部分大多由電磁機(jī)構(gòu)組成，在受控電器中，感測(cè)部分通常為操作手柄等；另一個(gè)是執(zhí)行部分，如觸點(diǎn)是根據(jù)指令進(jìn)行電路的接通或切斷的。</p><p

方式是將電氣設(shè)備的金屬外殼與工作零線相接的保護(hù)系統(tǒng)，稱作接零保護(hù)系統(tǒng)，用 TN 表示。IT 方式是電源側(cè)沒(méi)有工作接地，或經(jīng)過(guò)高阻抗接地。負(fù)載側(cè)電氣設(shè)備進(jìn)行接地保護(hù)的保護(hù)系統(tǒng)。一級(jí)負(fù)荷：中斷供電將造成人身傷亡者；或***、經(jīng)濟(jì)上將造成重大損者。二級(jí)負(fù)荷：二級(jí)負(fù)荷為中斷供電將在***、經(jīng)濟(jì)上造成較大損失者，三級(jí)負(fù)荷：三級(jí)負(fù)荷為一般的電力負(fù)荷。</p><div
