padding: 0px;"> 2、常用電工測量儀表有哪幾種類型？ <br /> 通常分為四種類型： <br /> (1)　直讀指示儀表。測量時通過指針偏轉(zhuǎn)，將要測量的電量直接讀出，如電壓表、電流表、功率表、萬用表等。 <br /> (2)　比較儀表。測量時需要與相應(yīng)的標(biāo)準(zhǔn)量進(jìn)行比較讀出二者的比值，如惠斯登電橋用來測量電阻，萬用電橋用來測量電容、電感。往往用來作為測量一些電學(xué)量以及檢驗其它儀器或儀表用。 <br /> (3)　圖示儀表。專門用來顯示兩個相關(guān)量的變化關(guān)系。如示波器，這種儀表直觀效果好，但只能作為粗測。 <br /> (4)　數(shù)字儀表。將被測的模擬量轉(zhuǎn)換成為數(shù)字量，直接讀出，例如常用的數(shù)字電壓表、數(shù)字萬用表等。 <br /> 電工儀表是怎樣分類的？對電工儀表有哪些基本要求？ <br /> 電工儀表的種類很多，通常有以下不同的分類方法。 <br /> (1)　按工作原理分：有電磁式、磁電式、電動式、感應(yīng)式、整流式、熱電式、靜電式、電子式等。 <br /> (2)　按被測量性質(zhì)分：有電流表、電壓表、功率表、歐姆表、電度表、功率因數(shù)表、頻率表、萬用表等。 <br /> (3)　根據(jù)使用方式分：有開關(guān)板式和可攜式。開關(guān)板式儀表通常固定在開關(guān)板或配電盤上，誤差較大?？蓴y式儀表一般誤差較小，準(zhǔn)確度高。 <br /> (4)　根據(jù)工作電流分：有直流儀表、交流儀表、交直流兩用儀表。 <br /> 為了保證測量結(jié)果的準(zhǔn)確、可靠，對電工儀表有如下幾點(diǎn)要求。 <br /> (1)　準(zhǔn)確度高、誤差小，其數(shù)值應(yīng)符合所屬準(zhǔn)確度的要求。 <br /> (2)　誤差不應(yīng)隨時間、溫度、濕度、外磁場等外界環(huán)境條件的影響而變化。 <br /> (3)　儀表本身消耗功率應(yīng)越小越好，否則在測量小的功率時，會引起較大的誤差。 <br /> (4)　儀表應(yīng)有足夠高的絕緣強(qiáng)度和耐壓能力，還應(yīng)有承受短時間過載的能力，以保證使用安全。 <br /> (5)　應(yīng)有良好的讀數(shù)裝置，被測量的數(shù)值應(yīng)能直接讀出。 <br /> (6)　構(gòu)造堅固，使用維護(hù)方便。 </font></p><p style="margin: 2px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: 微軟雅黑, Arial, 宋體; color: rgb(24, 24, 24);"><font style="font-size: 15px; margin: 0px; padding: 0px;"> 電工儀表的標(biāo)志符號有哪些？常用儀表的類型和應(yīng)用范圍？ <br /> 電工儀表的刻度盤上標(biāo)有各種符號，以表示儀表的類型、測量對象、測量范圍、準(zhǔn)確度以及使用條件等。 <br /> 常用電工儀表的類型和應(yīng)用范圍見表1。 <br /> 電工儀表的準(zhǔn)確度等級分為0.1、0.2、0.5、1.0、1.5、2.5、5.0共七級，數(shù)字越小表示準(zhǔn)確度越高。按防御外界磁場或電場干擾的能力，分為Ⅰ、Ⅱ、Ⅲ、Ⅳ四等，其中Ⅰ等的防御能力。按使用條件分為A、B、C三組，A、B兩組用于室內(nèi)，C組用于室外或船艦、飛機(jī)、車輛上。 <br /> 如何正確使用和合理選擇電工測量儀表？ <br /> 為了避免由于測量方法不完善而引起測量的誤差，必須注意正確使用儀表，主要應(yīng)注意下面幾點(diǎn)： <br /> (1)　按測量對象的性質(zhì)選擇儀表類型。首先視被測量的是直流還是交流，以便選用直流儀表或交流儀表。如果測量交流量，還要注意是正弦波還是非正弦波；測量時還要區(qū)分被測量的究竟是平均值、有效值、瞬時值、還是大值，對于交流量還要注意頻率。 <br /> (2)　按測量對象的實際需要，選擇儀表等級。根據(jù)工程性質(zhì)，只要使測量結(jié)果的誤差在工程實際允許范圍內(nèi)即可。例如常用的標(biāo)準(zhǔn)和部分精密測量中，可用準(zhǔn)確度0.1到0.2級的儀表；在實驗測量中可用0.5到1.5級的儀表；在工廠生產(chǎn)中可用1.0到5.0級的儀表。 <br /> (3)　按測量對象和測量線路的電阻大小選擇儀表內(nèi)阻。對測量電壓的電壓表，內(nèi)阻越大越好，要求電壓表內(nèi)阻值要大于被測對象100倍較好。對測量電流的電流表，內(nèi)阻越小越好，常要求電流表內(nèi)阻小于被測對象100倍。 <br /> (4)　按測量對象選擇儀表的允許額定值。不要用大量程的儀表去測量小量值，避免讀數(shù)不準(zhǔn)。當(dāng)然更不可用小量程儀表去測量大電量，以免損壞儀表。所以，在選用儀表時，必須認(rèn)真觀察儀表和設(shè)備允許承受的額定電壓、額定電流和額定功率。 </font> </p><p class="MsoNormal" style="margin: 0cm 0cm 0pt;
