工頻交換耐壓實驗通用方式及實驗步驟

工頻(pin)傳遞耐壓試驗(yan)實驗(yan)具體方法

傳統按照

有繞阻的被試(shi)品(pin)抑制擊穿電壓實(shi)驗操作時，應將被試(shi)品(pin)繞阻實(shi)際上(shang)的兩(liang)面短(duan)接，非被試(shi)品(pin)繞阻亦應短(duan)接并與的外(wai)殼毗連后一定接地。

調換耐壓(ya)試驗試驗時加(jia)至試驗電阻值后(hou)的延續(xu)性時期，如(ru)無十(shi)分聲明函則均為(wei)1min。

升(sheng)壓(ya)(ya)(ya)一定從零(ling)起頭，切(qie)不精(jing)準打擊送電(dian)(dian)(dian)(dian)。升(sheng)壓(ya)(ya)(ya)流(liu)速在75%檢(jian)(jian)測(ce)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)時候，是可(ke)以(yi)是姿意的(de)，自75%電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)起頭應(ying)年均(jun)(jun)升(sheng)壓(ya)(ya)(ya)，約為(wei)每秒2%檢(jian)(jian)測(ce)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)流(liu)速升(sheng)壓(ya)(ya)(ya)(以(yi) DL 474.4-92《直(zhi)播(bo) 絕(jue)緣帶檢(jian)(jian)測(ce)履行(xing)導則(ze) 互換(huan)抗(kang)壓(ya)(ya)(ya)檢(jian)(jian)測(ce)》起算)。抗(kang)壓(ya)(ya)(ya)檢(jian)(jian)測(ce)后(hou)，迅捷年均(jun)(jun)降血壓(ya)(ya)(ya)到零(ling)，隨后(hou)封控(kong)24v電(dian)(dian)(dian)(dian)源(yuan)。

工頻交流耐沖擊實驗流程

不(bu)管什么被試品在應(ying)(ying)對(dui)對(dui)調抗壓科(ke)(ke)(ke)學(xue)(xue)試驗(yan)前，應(ying)(ying)該先應(ying)(ying)對(dui)此外接地科(ke)(ke)(ke)學(xue)(xue)試驗(yan)及格后再應(ying)(ying)對(dui)抗壓科(ke)(ke)(ke)學(xue)(xue)試驗(yan)。本身在抗壓科(ke)(ke)(ke)學(xue)(xue)試驗(yan)前后輪(lun)均應(ying)(ying)仗(zhang)量(liang)接地熱敏(min)電阻(zu)。

同(tong)個(ge)，充油紫裝若經濾油或公(gong)路運(yun)輸，擊(ji)穿電(dian)壓試(shi)(shi)驗前還應將(jiang)試(shi)(shi)品靜置一小段同(tong)時，以取消外觀要殘存的(de)的(de)氛(fen)圍。插上試(shi)(shi)品，掛斷電(dian)壓，起頭升(sheng)壓打擊(ji)試(shi)(shi)驗。升(sheng)壓線(xian)程(cheng)池(chi)中應融(rong)洽好(hao)感監管油田(tian)二(er)次回路，被試(shi)(shi)品如何極(ji)其的(de)聲(sheng)響。

上升工(gong)(gong)作(zuo)設(she)計(ji)輸出(chu)功率，起頭記時。時間到后(hou)，降血壓(ya)隨(sui)后(hou)封控24v電源。工(gong)(gong)作(zuo)設(she)計(ji)中(zhong)如(ru)無絞碎性電流生成，則總以為(wei)所經程序(xu)耐壓(ya)試驗工(gong)(gong)作(zuo)設(she)計(ji)。

在升壓(ya)(ya)和耐(nai)沖擊速度中，如(ru)發明權功率表唆(suo)使逐漸曾加，調壓(ya)(ya)器(qi)往上漲標(biao)底最終目的條理，展示功率上漲、電壓(ya)(ya)電流根據穩定可(ke)靠和有升空的趨近(jin)，被試(shi)品起煙、焦臭、閃絡、滅(mie)掉或收取熱擊穿(chuan)聲音，要即抵(di)御(yu)升壓(ya)(ya)，穩壓(ya)(ya)停水(shui)后查(cha)抄前因后果。許多(duo)情景如(ru)查(cha)實(shi)是隔絕有些展示的則為被試(shi)品對換耐(nai)沖擊實(shi)驗室不及格。

如一定會被(bei)試品的本身閃絡是(shi)可(ke)能分為濕球溫度或本身臟污等(deng)而至(zhi)，應將被(bei)試品清潔瑣(suo)碎處里后(hou)，再杜絕實驗設計。
