耐壓測(cè)試是指對(duì)各種電器裝置、絕緣材料和絕緣結(jié)構(gòu)的耐受電壓能力進(jìn)行的測(cè)試，湖北3259測(cè)試儀。在不破壞絕緣材料性能的情況下，對(duì)絕緣材料或絕緣結(jié)構(gòu)施加高電壓的過程稱為耐壓試驗(yàn)。一般來講，湖北3259測(cè)試儀，耐壓測(cè)試主要目的是檢查絕緣耐受工作電壓或過電壓的能力，進(jìn)而檢驗(yàn)產(chǎn)品設(shè)備的絕緣性能是否符合安全標(biāo)準(zhǔn)。 </p> <p> 按照IEC61010的規(guī)定，測(cè)試電壓必須在5s內(nèi)逐漸地上升到所要求的試驗(yàn)電壓值（例如5kV等），保證試驗(yàn)電壓值穩(wěn)定加在被測(cè)絕緣體上不少于5s，此時(shí)所測(cè)回路的漏電流值與標(biāo)準(zhǔn)規(guī)定的泄漏電流閾值相比較，就可以判斷被測(cè)產(chǎn)品的絕緣性能是否符合標(biāo)準(zhǔn)。測(cè)試結(jié)束后，試驗(yàn)電壓必須在規(guī)定的時(shí)間內(nèi)逐漸地降至零。恒流源是一種寬頻譜、高精度交流穩(wěn)流電源，具有響應(yīng)速度快，湖北3259測(cè)試儀、恒流精度高、能長(zhǎng)期穩(wěn)定工作.湖北3259測(cè)試儀</p><div

變壓器剛出產(chǎn)時(shí)，沒有經(jīng)過惡劣環(huán)境長(zhǎng)時(shí)間的考驗(yàn)，外施其額定電壓和頻率的電源作試驗(yàn)，繞組匝間、層間和段間的電壓不足以達(dá)到電介質(zhì)缺陷處的擊穿電壓難以造成這些絕緣缺陷處的放電和擊穿，這種存在絕緣故障隱患的變壓器與絕緣性能良好的同類變壓器的空載電流和空載功耗沒有太大的差別，故而難以發(fā)現(xiàn)這些隱患； </p> <p> 而感應(yīng)耐壓試驗(yàn)給變壓器施加2倍額定電壓以上的電壓，可在縱絕緣缺陷處建立更高更集中的場(chǎng)強(qiáng)，繞組匝間、層間和段間的電壓達(dá)到并超過電介質(zhì)缺陷處的擊穿電壓；感應(yīng)耐壓試驗(yàn)給變壓器施加頻率在2倍的額定頻率以上，較高的頻率又可以大幅降低固體電介質(zhì)的擊穿電壓，使得絕緣缺陷更容易被擊穿；感應(yīng)耐壓試驗(yàn)所規(guī)定的外施電壓的作用時(shí)間亦可保證絕緣缺陷的擊穿；故感應(yīng)耐壓試驗(yàn)可以可靠地檢測(cè)出變壓器縱絕緣性能的好壞。絕緣耐電壓測(cè)試儀又叫電氣絕緣強(qiáng)度試驗(yàn)儀或叫介質(zhì)強(qiáng)度測(cè)試儀。</p><div
