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
