Kuipa kwa Mayeso a Direct Current (DC).
(1) Pokhapokha ngati palibe capacitance pa chinthu choyezedwa, voteji yoyezetsa iyenera kuyambira pa "zero" ndikukwera pang'onopang'ono kuti isatengeke kwambiri.Mpweya wowonjezera umakhalanso wotsika.Kulipiritsa kukakhala kwakukulu kwambiri, kumapangitsa kuti woyesayo asaganize molakwika ndikupangitsa kuti zotsatira zake zikhale zolakwika.
(2) Popeza kuti DC imapirira mayeso amagetsi idzapereka chinthucho poyesedwa, pambuyo pa kuyesedwa, chinthu chomwe chikuyesedwa chiyenera kutulutsidwa musanayambe kupita ku sitepe yotsatira.
(3) Mosiyana ndi mayeso a AC, kuyesa kwa magetsi kwa DC kumatha kuyesedwa ndi polarity imodzi.Ngati chinthucho chiyenera kugwiritsidwa ntchito pansi pa magetsi a AC, kuipa kumeneku kuyenera kuganiziridwa.Ichi ndichifukwa chake ambiri owongolera chitetezo amalimbikitsa kugwiritsa ntchito kuyesa kwa AC kupirira.
(4) Panthawi ya AC test test voltage, mtengo wapamwamba wa voteji ndi 1.4 kuwirikiza mtengo womwe umawonetsedwa ndi mita yamagetsi, womwe sungathe kuwonetsedwa ndi mita yamagetsi wamba, komanso sungapezeke ndi DC kupirira mayeso amagetsi.Chifukwa chake, malamulo ambiri oteteza chitetezo amafuna kuti ngati kuyesa kwamagetsi kwa DC kukugwiritsidwa ntchito, magetsi oyeserera amayenera kukulitsidwa mpaka pamtengo wofanana.
Pambuyo poyesa kupirira kwa DC kumalizidwa, ngati chinthu chomwe chikuyesedwa sichikutulutsidwa, n'zosavuta kuchititsa mantha amagetsi kwa woyendetsa;ma DC athu onse opirira ma voltage testers ali ndi ntchito yotulutsa mwachangu ya 0.2s.Pambuyo poyesa kupirira kwa DC kumalizidwa, tester Imatha kutulutsa magetsi pathupi loyesedwa mkati mwa 0.2s kuteteza chitetezo cha wogwiritsa ntchito.
Chidziwitso cha zabwino ndi zoyipa za AC kupirira mayeso amagetsi
Pakuyezetsa voteji, voteji yomwe imagwiritsidwa ntchito ndi tester voltage tester ku thupi loyesedwa imatsimikiziridwa motere: kuchulukitsa mphamvu yogwira ntchito ya thupi loyesedwa ndi 2 ndikuwonjezera 1000V.Mwachitsanzo, voteji yogwira ntchito ya chinthu choyesedwa ndi 220V, pamene test test tester ikuchitika, voteji ya tester tester ndi 220V+1000V=1440V, nthawi zambiri 1500V.
Kuyesa kwamagetsi kumagawidwa kukhala kuyesa kwamagetsi kwa AC ndi kuyesa kwamagetsi kwa DC;ubwino ndi kuipa kwa AC test test voltage ndi motere:
Ubwino wa AC kupirira mayeso amagetsi:
(1) Nthawi zambiri, kuyesa kwa AC ndikosavuta kuvomerezedwa ndi chitetezo kuposa kuyesa kwa DC.Chifukwa chachikulu ndi chakuti mankhwala ambiri amagwiritsa ntchito alternating panopa, ndi alternating panopa mayeso akhoza kuyesa zabwino ndi zoipa polarity wa mankhwala pa nthawi yomweyo, zomwe zimagwirizana kwathunthu ndi chilengedwe chimene mankhwala ntchito ndi mu mzere. ndi momwe mungagwiritsire ntchito.
(2) Popeza ma capacitor osokera sangathe kulipira mokwanira pa mayeso a AC, koma sipadzakhala nthawi yomweyo inrush pano, kotero palibe chifukwa chololeza voteji yoyeserera kukwera pang'onopang'ono, ndipo voteji yonse imatha kuwonjezeredwa kumayambiriro kwa kuyesa, pokhapokha ngati mankhwalawo ali ndi chidwi ndi mphamvu ya inrush kwambiri.
(3) Popeza kuyesa kwa AC sikungathe kudzaza ma capacitances osokera, palibe chifukwa chochotsera chinthu choyesera pambuyo pa mayesero, omwe ndi ubwino wina.
Kuipa kwa AC kupirira mayeso amagetsi:
(1) Choyipa chachikulu ndi chakuti ngati mphamvu yosokera ya chinthu choyezedwa ndi yayikulu kapena chinthu choyezedwa ndi katundu wa capacitive, magetsi opangidwa adzakhala aakulu kwambiri kuposa momwe akuthawira panopa, kotero kuti kutayikira kwenikweni sikungathe kudziwika.panopa.
(2) Choyipa china ndi chakuti popeza panopa chofunika ndi mphamvu yosokera ya chinthu choyesedwa chiyenera kuperekedwa, zomwe zikuchitika panopa ndi makina zidzakhala zazikulu kwambiri kuposa zomwe zilipo panopa pogwiritsira ntchito kuyesa kwa DC.Izi zimawonjezera chiopsezo kwa wogwiritsa ntchito.
Kodi pali kusiyana kotani pakati pa kuzindikira kwa arc ndi kuyesa kwapano?
1. Ponena za kugwiritsa ntchito arc kuzindikira ntchito (ARC).
a.Arc ndizochitika zakuthupi, makamaka ma voteji othamanga kwambiri.
b.Zinthu zopanga: kukhudzidwa kwa chilengedwe, zotsatira zake, zotsatira za zinthu.
c.Arc imakhudzidwa kwambiri ndi aliyense, komanso ndichimodzi mwazinthu zofunika pakuyezera mtundu wazinthu.
d.Pulogalamu ya RK99 yoyendetsedwa ndi ma voltage tester opangidwa ndi kampani yathu ili ndi ntchito yozindikira arc.Imayesa siginecha yothamanga kwambiri yomwe ili pamwamba pa 10KHz kudzera pasefa yodutsa kwambiri yomwe imayankha pafupipafupi pamwamba pa 10KHz, kenako ndikuiyerekeza ndi benchmark ya chida kuti mudziwe ngati ili yoyenera.Fomu yamakono ikhoza kukhazikitsidwa, ndipo mawonekedwe a mlingo angathenso kukhazikitsidwa.
e.Momwe mungasankhire mlingo wokhudzidwa uyenera kukhazikitsidwa ndi wogwiritsa ntchito molingana ndi mawonekedwe a mankhwala ndi zofunikira.
