安規(guī)測試儀注意事項 注意的是直流高壓輸出是負(fù)電壓,而地為正極。測試電容時,在電容器兩端加上電壓時有一充電過程,此時在測試電路中有一充電電流,當(dāng)該電流大于所設(shè)定的漏電電流值時,耐壓測試儀就會報警,使測試中斷,無法進行。因此,安規(guī)測試儀在測試時,應(yīng)緩慢增加電壓,充電電流小于所設(shè)定的漏電電流值,直到規(guī)定測試電壓,進行測試。而不能采用固定電壓,復(fù)位—啟動方式進行測試.在交流回路中相當(dāng)于直流回路中的電阻,因此,安規(guī)測試儀在交流回路中就產(chǎn)生一個電流,當(dāng)該電流大于所設(shè)定的漏電流值時,耐壓測試儀就會報警,使得測試中斷,無法進行。因此,在測試前,應(yīng)先計算好電容器的容抗(Xc),再算出在測試電壓下的回路電流值,然后調(diào)節(jié)耐壓測試儀漏電流預(yù)置值,使其略大于回路電流值,再進行測試。J)測試電纜等分布電容大的元件(設(shè)備)要等同于電容器測試。
