耐壓(ya)(ya)(ya)測(ce)試是(shi)指對各種(zhong)電(dian)(dian)器裝置(zhi)、絕(jue)緣(yuan)(yuan)(yuan)材料和絕(jue)緣(yuan)(yuan)(yuan)結構的(de)(de)耐受(shou)電(dian)(dian)壓(ya)(ya)(ya)能(neng)(neng)力進(jin)行的(de)(de)測(ce)試。在不(bu)破壞絕(jue)緣(yuan)(yuan)(yuan)材料性能(neng)(neng)的(de)(de)情(qing)況下，對絕(jue)緣(yuan)(yuan)(yuan)材料或絕(jue)緣(yuan)(yuan)(yuan)結構施加高(gao)電(dian)(dian)壓(ya)(ya)(ya)的(de)(de)過程稱為耐壓(ya)(ya)(ya)試驗(yan)(yan)。一(yi)般來(lai)講，耐壓(ya)(ya)(ya)測(ce)試主要(yao)目的(de)(de)是(shi)檢查絕(jue)緣(yuan)(yuan)(yuan)耐受(shou)工作(zuo)電(dian)(dian)壓(ya)(ya)(ya)或過電(dian)(dian)壓(ya)(ya)(ya)的(de)(de)能(neng)(neng)力，進(jin)而檢驗(yan)(yan)產品設備的(de)(de)絕(jue)緣(yuan)(yuan)(yuan)性能(neng)(neng)是(shi)否符合(he)**標準。

耐壓(ya)(ya)測(ce)試(shi)(shi)(shi)的(de)(de)基(ji)本原理:把一(yi)個(ge)高于正常工作的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)加在(zai)(zai)被(bei)(bei)(bei)測(ce)設(she)備的(de)(de)絕緣體(ti)上(shang)，并持續一(yi)段規(gui)定(ding)(ding)的(de)(de)時(shi)(shi)間，如(ru)果(guo)其(qi)間的(de)(de)絕緣性足夠好(hao)，加在(zai)(zai)上(shang)面的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)就(jiu)只會產生很小(xiao)的(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)。如(ru)果(guo)一(yi)個(ge)被(bei)(bei)(bei)測(ce)設(she)備絕緣體(ti)在(zai)(zai)規(gui)定(ding)(ding)的(de)(de)時(shi)(shi)間內(nei)(nei)，其(qi)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)保持在(zai)(zai)規(gui)定(ding)(ding)的(de)(de)范圍內(nei)(nei)，就(jiu)可(ke)以(yi)確定(ding)(ding)這個(ge)被(bei)(bei)(bei)測(ce)設(she)備可(ke)以(yi)在(zai)(zai)正常的(de)(de)運行條件下(xia)**運行。進行耐壓(ya)(ya)測(ce)試(shi)(shi)(shi)時(shi)(shi)，技術規(gui)格不(bu)(bu)同被(bei)(bei)(bei)測(ce)試(shi)(shi)(shi)品，測(ce)量標準也就(jiu)不(bu)(bu)同。對一(yi)般被(bei)(bei)(bei)測(ce)設(she)備，耐壓(ya)(ya)測(ce)試(shi)(shi)(shi)是測(ce)量火(huo)線與機殼之間的(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)值，基(ji)本規(gui)定(ding)(ding)是:以(yi)兩倍(bei)于被(bei)(bei)(bei)測(ce)物的(de)(de)工作電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)再(zai)加1000V作為測(ce)試(shi)(shi)(shi)的(de)(de)標準電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)。部分產品的(de)(de)測(ce)試(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)可(ke)能高于這一(yi)規(gui)定(ding)(ding)值。按照IEC61010的(de)(de)規(gui)定(ding)(ding)，測(ce)試(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)必須(xu)在(zai)(zai)5s內(nei)(nei)逐漸(jian)地上(shang)升(sheng)到所(suo)要求的(de)(de)試(shi)(shi)(shi)驗電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(例如(ru)5kV等)，保證試(shi)(shi)(shi)驗電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值穩定(ding)(ding)加在(zai)(zai)被(bei)(bei)(bei)測(ce)絕緣體(ti)上(shang)不(bu)(bu)少(shao)于5s，此時(shi)(shi)所(suo)測(ce)回(hui)路(lu)的(de)(de)漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)值與標準規(gui)定(ding)(ding)的(de)(de)泄漏(lou)(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)閾值相(xiang)比較(jiao)，就(jiu)可(ke)以(yi)判斷被(bei)(bei)(bei)測(ce)產品的(de)(de)絕緣性能是否符合標準。測(ce)試(shi)(shi)(shi)結束后，試(shi)(shi)(shi)驗電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)必須(xu)在(zai)(zai)規(gui)定(ding)(ding)的(de)(de)時(shi)(shi)間內(nei)(nei)逐漸(jian)地降至(zhi)零(ling)。
