耐壓測(cè)試的基本原理：把一個(gè)高于正常工作的電壓加在被測(cè)設(shè)備的絕緣體上，并持續(xù)一段規(guī)定的時(shí)間，如果其間的絕緣性足夠好，加在上面的電壓就只會(huì)產(chǎn)生很小的漏電流。如果一個(gè)被測(cè)設(shè)備絕緣體在規(guī)定的時(shí)間內(nèi)，其漏電電流保持在規(guī)定的范圍內(nèi)，就可以確定這個(gè)被測(cè)設(shè)備可以在正常的運(yùn)行條件下安全運(yùn)行。進(jìn)行耐壓測(cè)試時(shí)，技術(shù)規(guī)格不同被測(cè)試品，測(cè)量標(biāo)準(zhǔn)也就不同。對(duì)一般被測(cè)設(shè)備，耐壓測(cè)試是測(cè)量火線與機(jī)殼之間的漏電流值，基本規(guī)定是：以兩倍于被測(cè)物的工作電壓再加1000V作為測(cè)試的標(biāo)準(zhǔn)電壓。部分產(chǎn)品的測(cè)試電壓可能高于這一規(guī)定值。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。上海串聯(lián)諧振耐壓測(cè)試儀</p><p>
