Kodi transformer ya ma frequency otsika ingalephereke bwanji?
Mwayi woti zinthu zilephereke umasiyana malinga ndi malo omwe zili.
Gwiritsani ntchito multimeter kuti muyese ubwino wa transformer yotsika kwambiri
1. Kuzindikira mwachindunji ndi zida zamagetsi
Ma multimeter ena a digito ali ndi ntchito yoyezera capacitance, ndipo miyeso yawo ndi 2000p, 20n, 200n ndi 2 μ Ndi 20 μ Fifth gear. Pakuyeza, ma pini awiri a capacitor otulutsidwa amatha kulowetsedwa mwachindunji mu Cx jack pa bolodi la mita. Mukasankha range yoyenera, deta yowonetsera imatha kuwerengedwa ndipo transformer imatha kuweruzidwa.
2. Dziwani ndi zida zodzitetezera
Njira yolipirira ya capacitor imathanso kuwonedwa ndi digito multimeter, yomwe imasonyeza kusintha kwa voltage yolipirira ndi kuchuluka kwa digito kosiyana. Ngati kuchuluka kwa muyeso wa digito multimeter ndi n times/sekondi, ndiye kuti panthawi yowonera njira yolipirira ya capacitor, kuwerenga kwa n kodziyimira pawokha komanso kotsatizana kumatha kuwonedwa sekondi iliyonse. Malinga ndi mawonekedwe owonetsera awa a digito multimeter, mtundu wa capacitor ukhoza kuzindikirika ndipo capacitance ikhoza kuyerekezedwa.
Zindikirani: Mfundo yodziwira ndi njira yodziwira ndi yofanana pa transformer ya ma frequency apamwamba komanso transformer ya ma frequency otsika.
Kukonza Zolakwika za Low Frequency Transformer
Kugawa ndi zomwe zimayambitsa zolakwika zomwe zimachitika kawirikawiri mu transformers
(1) Mavuto omwe amakhalapo pamene transformer ikuperekedwa. Monga malekezero omasuka, ma cushion blocks omasuka, kuwotcherera koyipa, kutchinjiriza kwapakati kosakwanira, mphamvu yochepa ya ma circuit, ndi zina zotero.
(2) Kusokonezeka kwa mzere. Kusokonezeka kwa mzere ndiye chinthu chofunikira kwambiri pazinthu zonse zomwe zimayambitsa ngozi za transformer. Makamaka zimaphatikizapo: kupitirira kwa magetsi komwe kumachitika panthawi yotseka, kuchuluka kwa magetsi omwe amafika pamlingo wotsika, vuto la mzere, kufalikira kwa kuwala ndi zina zachilendo. Vuto lamtunduwu limakhala lalikulu kwambiri pa zolakwika za transformer. Chifukwa chake, mayeso oteteza kugwedezeka ayenera kuchitika pa transformer nthawi zonse kuti azindikire mphamvu ya transformer motsutsana ndi mphamvu yamagetsi yolowera.
(3) Kutha kwa kukalamba kwa insulation ya transformer chifukwa cha kugwiritsa ntchito molakwika kumawonjezeka. Nthawi yapakati ya ntchito ya transformer ndi zaka 17.8 zokha, zomwe ndi zochepa kwambiri kuposa nthawi yomwe imayembekezeredwa ya zaka 35-40.
(4) Mphamvu yamagetsi yochulukirapo yomwe imayambitsidwa ndi mphezi.
(5) Kuchuluka kwa mphamvu. Kuchuluka kwa mphamvu kumatanthauza transformer yomwe ikugwira ntchito mopitirira mphamvu ya dzina kwa nthawi yayitali. Kuchuluka kwa mphamvu nthawi zambiri kumachitika pamene chomera chamagetsi chikupitirira kukulitsa katundu pang'onopang'ono, chipangizo choziziritsira chikugwira ntchito molakwika, vuto la mkati mwa transformer, ndi zina zotero, ndipo pamapeto pake zimapangitsa transformer kupitirira mphamvu. Kutentha kwakukulu komwe kumachitika kudzapangitsa kuti insulation ikule msanga. Pamene khadi yotetezera kutentha ya transformer ikakalamba, mphamvu ya pepala idzachepa. Chifukwa chake, zotsatira za zolakwika zakunja zitha kubweretsa kuwonongeka kwa insulation, zomwe zingayambitse zolakwika.
(6) Kunyowetsa madzi: ngati pali kusefukira kwa madzi, kutayikira kwa mapaipi, kutayikira kwa chivundikiro cha mutu, kulowerera kwa madzi mu thanki yamafuta m'mbali mwa chikwama kapena zowonjezera, komanso pali madzi mu mafuta otetezera kutentha, ndi zina zotero.
(7) Kukonza bwino sikunachitike.
