Qhov kev kuaj AC Hipot tiag tiag yog dab tsi, thiab vim li cas nws thiaj li "kev puas tsuaj" tseem tsis tau?
AC Hipot xeem siv AC voltage ntau dua li qhov ntsuas hluav taws xob rau 60 vib nas this. Nws paub tseeb tias kev rwb thaiv tsev tuaj yeem muaj sia nyob qhov phem tshaj overvoltage nws yuav ntsib hauv kev pabcuam.
Sib piv nrog rau lwm yam kev xeem:

Rwb thaiv tsev mob ntawm DC low voltage |
Tsis simulate AC stress distribution |

Dielectric poob |
rhiab heev rau noo noo, tsis tag nrho cov teeb meem |

AC Hipot |
Nws puas tuaj yeem muaj sia nyob qhov phem tshaj - rooj plaub overvoltage? |
Tsis tuaj yeem localize defect (pass / poob xwb) |
Qhov "destructive" xwm piav qhia:
• Cov rwb thaiv tsev noj qab haus huv → hla tsis muaj kev puas tsuaj (tsis yog- puas tsuaj rau cov rwb thaiv tsev zoo).
• Cov rwb thaiv tsev tsis muaj zog → tawg thaum lub sij hawm sim (xov xwm - zoo dua hauv lub Hoobkas dua thaum muaj cua daj cua dub).
Kev lees txais IEC (IEC 60060-1):
• Tsis muaj kev cuam tshuam cuam tshuam (flashover lossis tawg) thaum lub sijhawm kuaj 60 thib ob.
