數(shù)字兆歐表、指針兆歐表、絕緣表、絕緣電阻測試儀、高壓絕緣電阻測試儀、絕緣電阻測量儀、絕緣特性測試儀、高壓兆歐表、帶吸收比功能的兆歐表、帶極化指數(shù)功能的兆歐表、電動(dòng)搖表、電子式絕緣電阻測試儀、大功率高壓兆歐表、袖珍數(shù)字兆歐表、數(shù)顯式搖表、高壓絕緣兆歐表、兆歐表功能 </p> <p> 1、數(shù)字兆歐表輸出功率大，浙江數(shù)字式絕緣電阻測試儀kew3023、帶載能力強(qiáng)，抗干擾能力強(qiáng) </p> <p> 本表外殼由**度鋁合金組成，機(jī)內(nèi)設(shè)有等電位保護(hù)環(huán)和四階有源低通濾波器，浙江數(shù)字式絕緣電阻測試儀kew3023，對(duì)外界工頻及強(qiáng)電磁場可起到有效的屏蔽作用。數(shù)字兆歐表對(duì)容性試品測量由于輸出短路電流大于1.6mA，很容易使測試電壓迅速上升到輸出電壓的額定值。對(duì)于低阻值測量由于采用比例法設(shè)計(jì)故電壓下落并不影響測試精度 </p> <p> 2、本數(shù)字兆歐表不需人力作功，由電池供電，量程可自動(dòng)轉(zhuǎn)換。一目了然的面板操作和LCD顯示使得測量十分方便和迅捷 </p> <p>

絕緣電阻測試儀是非常重要的故障診斷工具，有效的絕緣電阻系統(tǒng)具有高的電阻值，通常大于幾個(gè)兆歐。差的絕緣系統(tǒng)具有較低的絕緣電阻。絕緣電阻測試儀作用：絕緣電阻測試儀用于測量絕緣電阻的直接作用模擬指示的電測量儀表，其單位用MΩ表示;端鈕電壓-儀表線路端鈕和接地端鈕之間的電壓;測量端鈕-絕緣電阻表用來連接被測量的接線端子。絕緣電阻表的測量端鈕應(yīng)分別標(biāo)出線路端鈕L，接地端鈕E，屏蔽端鈕G的標(biāo)志符。絕緣電阻測試儀的日常維護(hù)如下：通常一般所有的電氣設(shè)備都是需要日常的維護(hù)的。維護(hù)的目的不簡單的是為了延長測試儀的使用壽命，也是為了發(fā)現(xiàn)可能存在的故障隱患或微小的故障。早點(diǎn)發(fā)現(xiàn)這些隱患或微小的故障，可以在減少帶來不必要的損失和人事傷害。絕緣電阻測試儀的日常維護(hù)通?？梢苑譃槎ㄆ诰S護(hù)和不定期維護(hù)，或根據(jù)為維護(hù)測試的目的分為預(yù)防性維護(hù)和預(yù)測性維護(hù)等等。

合成電阻的方法由于受到設(shè)計(jì)成本和尺寸規(guī)格的限制被排除在外。采用的是分立式高壓電阻器矩陣的方法，組成一個(gè)陣列，能夠提供500,000多種電阻值輸出。在這種校準(zhǔn)器中，有8個(gè)范圍的電阻值，覆蓋了10kΩ到10 GΩ的范圍，每個(gè)范圍均能提供4.5 位的穩(wěn)定輸出。 </p> <p> 收**適的高壓電阻器并將其集成到一個(gè)儀器內(nèi)又存在另一項(xiàng)挑戰(zhàn)。這就是與歐盟CE認(rèn)證的一項(xiàng)強(qiáng)制性要求《低電壓指令》相關(guān)的安全性標(biāo)準(zhǔn)挑戰(zhàn)。與儀器制造商相關(guān)的標(biāo)準(zhǔn)是EN 61010－測量、控制和實(shí)驗(yàn)室用電氣設(shè)備的安全要求。 </p> <p> 低電壓指令要求將校準(zhǔn)器電壓限制為1,000Vrms。那么如何校準(zhǔn)測試電壓高達(dá)5 kV 的兆歐表呢？這類儀器具有更寬的動(dòng)態(tài)范圍，可測量高到10TΩ的電阻，并且提供了如上所述的保護(hù)端子，使其能夠準(zhǔn)確測量非常高的電阻值。幸運(yùn)的是，這樣的保護(hù)配置可以使其本身形成一個(gè)電阻倍增器，能夠有效地將一個(gè)已知電阻倍增為1000倍。同樣重要的是，由于倍增器是一個(gè)分立、隔離、**的設(shè)備，可以滿足倍增器所需的高電壓，它已經(jīng)不是《低電壓指令》所管轄的范圍。浙江數(shù)字式絕緣電阻測試儀kew3023</p><p>
