Ndizotheka bwanji kuti thiransifoma yotsika kwambiri ingalephere
Kuthekera kwa kulephera kumasiyanasiyana ndi tsamba.
Gwiritsani ntchito ma multimeter kuyeza mtundu wa chosinthira chotsika kwambiri
1.Kuzindikira mwachindunji ndi zida za capacitive
Ma multimeter ena a digito ali ndi ntchito yoyezera mphamvu, ndipo miyeso yawo yoyezera ndi 2000p, 20n, 200n ndi 2 μ Ndi 20 μ Fifth gear.Poyezera, zikhomo ziwiri za capacitor zotulutsidwa zimatha kulowetsedwa mwachindunji mu jack Cx pa bolodi la mita.Pambuyo posankha mtundu woyenera, deta yowonetsera ikhoza kuwerengedwa ndipo transformer ikhoza kuweruzidwa.
2. Dziwani ndi zida zotsutsa
Njira yolipirira ya capacitor imathanso kuwonedwa ndi ma multimeter a digito, omwe amawonetsa kusintha kwa voteji yolipiritsa ndi kuchuluka kwa digito.Ngati kuchuluka kwa kuyeza kwa multimeter ya digito ndi n nthawi / sekondi, ndiye pakuwonera njira yolipiritsa ya capacitor, n zowerengera zodziyimira pawokha komanso motsatizana zitha kuwoneka sekondi iliyonse.Malinga ndi chiwonetserochi cha multimeter ya digito, mtundu wa capacitor ukhoza kuzindikirika ndipo mphamvu yake imatha kuyerekezedwa.
Zindikirani: Mfundo yodziwikiratu ndi njira yofananira ndi ma transfoma apamwamba kwambiri komanso otsika kwambiri.
Kukonza Kolakwika kwa Low Frequency Transformer
Kugawika ndi zomwe zimayambitsa zolakwika zomwe zimachitika mu thiransifoma
(1) Mavuto omwe alipo pamene transformer imaperekedwa.Monga malekezero otayirira, midadada yotayirira, kuwotcherera kosakwanira, kutsekereza kwapakati, kusakwanira kwamphamvu kwafupipafupi, ndi zina zambiri.
(2) Kusokoneza mzere.Kusokoneza kwa mzere ndiye chinthu chofunikira kwambiri pazifukwa zonse zomwe zimayambitsa ngozi za transformer.Zimaphatikizanso: ma voliyumu opitilira muyeso omwe amapangidwa potseka, nsonga yamagetsi pamalo otsika kwambiri, vuto la mzere, flash over ndi zochitika zina zachilendo.Kulakwitsa kwamtunduwu kumatenga gawo lalikulu mu zolakwika za transformer.Chifukwa chake, kuyesa kwachitetezo chachitetezo kuyenera kuchitika pa thiransifoma pafupipafupi kuti muwone mphamvu ya chosinthira motsutsana ndi inrush pano.
(3) Kuthamanga kwa ukalamba kwa thiransifoma kusungunula chifukwa chogwiritsa ntchito molakwika kumafulumizitsa.Avereji yautumiki wa osintha ambiri ndi zaka 17.8 zokha, zomwe ndizotsika kwambiri kuposa moyo wautumiki womwe ukuyembekezeka wazaka 35-40.
(4) Kuchuluka kwamagetsi chifukwa cha mphezi.
(5) Kuchulukitsitsa.Kuchulukira kumatanthawuza thiransifoma yomwe ikugwira ntchito yopitilira mphamvu ya nameplate kwa nthawi yayitali.Kuchulukirachulukira nthawi zambiri kumachitika pamene magetsi akupitiriza kuwonjezereka pang'onopang'ono, chipangizo chozizira chimagwira ntchito mosadziwika bwino, zolakwika zamkati za thiransifoma, ndi zina zotero, ndipo pamapeto pake zimapangitsa kuti thiransifomayo iwonongeke.Chifukwa cha kutentha kwambiri kumabweretsa kukalamba msanga kwa kutchinjiriza.Pamene insulating makatoni wa thiransifoma mibadwo, pepala mphamvu adzachepa.Choncho, zotsatira za zolakwika zakunja zingayambitse kuwonongeka kwa insulation, zomwe zingayambitse zolakwika.
(6) Damping: ngati pali kusefukira kwa madzi, kutayikira kwa mapaipi, kutayikira kwa chivundikiro chamutu, kulowerera kwamadzi mu thanki yamafuta pamanja kapena zina, ndipo pali madzi mumafuta oteteza, ndi zina zambiri.
(7) Kusamalira bwino sikunachitike.
