1. Mpweya wowononga umayambitsa kulephera kwa galimoto.Mpweya wowononga umakhalapo pamisonkhano ya opanga mankhwala ena, zomwe zitha kukhala chimodzi mwazomwe zimayambitsa kulephera kwagalimoto, motere:
(1) Kusagwirizana kwa ma switch ndi ma relay omwe amayamba chifukwa cha mpweya wowononga kumabweretsa kulephera kwa Converter.
(2) Kulephera kwa chosinthira kumayamba chifukwa chafupipafupi pakati pa makhiristo omwe amayamba chifukwa cha mpweya wowononga.
(3) Dera lalikulu ndi lalifupi lozungulira chifukwa cha dzimbiri zowonongeka, zomwe zimabweretsa kulephera kwa Converter.
(4) Kulakwitsa kwa inverter chifukwa chafupipafupi pakati pa zigawo chifukwa cha dzimbiri la board board.
2. Kulephera kotembenuza pafupipafupi komwe kumachitika chifukwa cha fumbi la conductive monga chitsulo.Zinthu zotere zomwe zimapangitsa kuti ma converter alephere kwambiri amakhalapo m'mabizinesi opanga ndi fumbi lalikulu monga migodi, kukonza simenti ndi malo omanga.
(1) Fumbi lochulukirachulukira monga chitsulo limapangitsa kuti dera lalifupi likhale lozungulira, zomwe zingayambitse kulephera kwa inverter.
(2) Kutentha kwa chipsepse chozizira kumakhala kokwera kwambiri chifukwa cha kutsekeka kwa fumbi, komwe kumayambitsa kugwedezeka ndikuwotcha, zomwe zimapangitsa kulephera kwa Converter.
3.Frequency converter kulephera chifukwa cha condensation, chinyezi, chinyezi ndi kutentha kwakukulu.Zinthu izi zomwe zimapangitsa kuti otembenuza alephere makamaka chifukwa cha nyengo kapena malo apadera a malo ogwiritsira ntchito.
(1) Mlongoti wa pachipata umatayika chifukwa cha chinyezi, zomwe zimapangitsa kuti musagwirizane bwino, zomwe zimapangitsa kuti otembenuza alephere.
(2) Chosinthira chinapunthwa chifukwa chakutentha kwambiri chifukwa cha kutentha kwambiri.
(3) Kulephera kwa otembenuza kumayambitsidwa ndi kuwomba pakati pa mbale zamkuwa za bolodi lalikulu la dera chifukwa cha chinyezi.
(4) Chinyezi chimayambitsa dzimbiri zamagetsi za kukana kwamkati kwa osinthira pafupipafupi ndi kusweka kwa waya, zomwe zimatsogolera kulephera kwa otembenuza pafupipafupi.
(5) Pali condensation mu pepala insulating, amene amachititsa chodabwitsa kukhetsa kusweka, motero kumabweretsa kulephera Converter.
4.Kulakwitsa kwa ma frequency converter chifukwa cha zinthu zaumunthu makamaka chifukwa cha kusankha kolakwika ndi chizindikiro chosasinthidwa kuti chigwiritsidwe ntchito moyenera.
(1) Kusankhidwa kwamtundu wolakwika wa ma frequency converter kumayambitsa kuchulukira kwa ma frequency converter, zomwe zimapangitsa kuti ma frequency converter alephere.
(2) Zosinthazi sizimasinthidwa kuti zigwiritsidwe ntchito bwino, kotero kuti wotembenuza pafupipafupi nthawi zambiri amayendetsa chitetezo ku over-current, over-voltage, etc., zomwe zimatsogolera kukalamba msanga kwa otembenuza pafupipafupi ndi kulephera.
