1、絕緣電阻是用絕緣電阻測試儀（10000V以下）或絕緣搖表（2500V以下）來測量，由于試驗電壓比較低，所以許多絕緣缺陷不容易被發(fā)現(xiàn)；耐壓試驗試驗電壓高，容易發(fā)現(xiàn)高壓設(shè)備的絕緣缺陷； </p> <p> 2、絕緣試驗由于試驗電壓低，不容易損壞被試設(shè)備；而耐壓試驗由于試驗電壓高，容易在打壓時損壞被試設(shè)備，特別是有些時候，雖然耐壓試驗通過了，但卻對被試設(shè)備造成了傷害，試驗人員就要再用低電壓的絕緣試驗，測試一下耐壓試驗后的被試設(shè)備的絕緣情況。江蘇多倍頻感應(yīng)耐壓測試儀浙江_耐壓絕緣測試儀多少錢？</p><div

(4)以上是傳統(tǒng)的耐電壓試驗儀的結(jié)構(gòu)組成。隨著電子技術(shù)及單片，計算機技術(shù)飛速發(fā)展;程控耐壓測試儀這幾年也發(fā)展很快，程控耐壓儀與傳統(tǒng)的耐壓儀不同之處主要是升壓部分。程控耐壓儀高壓升壓不是通過市電由調(diào)壓器來調(diào)節(jié)，而是通過單片計算機控制產(chǎn)生一個50Hz或60Hz的正弦波信號再通過功率放大電路進行放大升壓，輸出電壓值也由單片計算機進行控制，其它部分原理與傳統(tǒng)耐壓儀差別不大。缺點:現(xiàn)場抗干擾性弱;可靠性不如機械式;成本高。 </p><p> 耐壓測試儀測試系統(tǒng)有三大模塊：程控電源模塊、信號采集調(diào)理模塊和計算機控制系統(tǒng)。程控電源模塊由輸出位0V~140V的程控電源和高壓變壓器構(gòu)成，在單片機ADCm842控制下程控電源輸出電壓經(jīng)變壓器升壓可以得到設(shè)定的輸出電壓值。 </p> <p> 模塊設(shè)計由于在實際的耐壓測試中，對不同產(chǎn)品可能要求施加不同的測試電壓，這就要求耐壓測試系統(tǒng)輸出測試電壓是可調(diào)的。PWM(Pulse Width Modulation)是控制逆變電源以實現(xiàn)可調(diào)電壓的輸出的主要方法之一。 </p> <p> PWM控制的理論基礎(chǔ)建立在采樣控制理論的一個重要結(jié)論上，即：沖量相等而形狀不同的窄脈沖加在具有慣性的環(huán)節(jié)上時，其效果基本相同。深圳絕緣耐壓測試儀廠家。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
