Resistance wire ndi mtundu wamba wa chigawo chokana, ndipo kuchuluka kwake kwapamwamba kumatanthawuza kachulukidwe kameneka kamene kamakhala pagawo lililonse. Kuwerengera molondola kuchuluka kwa waya wotsutsa ndikofunikira kuti zitsimikizire kuti zimagwira ntchito bwino komanso moyo wake wautumiki. Nkhaniyi ifotokoza momwe mungawerengere kuchuluka kwa mawaya olimbana ndi mawaya ndi njira zodzitetezera.

Choyamba, tiyenera kumvetsetsa tanthauzo la katundu wa pamwamba. Katundu wapamtunda amatanthauza kachulukidwe wapano (A/cm ^ 2) wotengedwa pagawo lililonse. Kuyimiridwa ndi formula:

Katundu wapamwamba=kachulukidwe kakali pano/malo apamtunda

Kuti tiwerenge katundu wa pamwamba pa waya wotsutsa, choyamba tiyenera kudziwa kachulukidwe kameneka. Kachulukidwe kakali pano akutanthauza kuchuluka kwa zomwe zikudutsa mugawo lodutsa magawo. Itha kuwerengedwa potengera kukana kwa zinthu za waya, mphamvu zamagetsi, komanso kutalika kwa waya, pogwiritsa ntchito njira iyi:

Kachulukidwe kakali pano=voltage/(mtengo wokana x kutalika)

Powerengera kachulukidwe kakali pano, mfundo zotsatirazi ziyenera kuzindikirika:

1. Sankhani mtengo woyenera wotsutsa: Mtengo wotsutsa wa waya wotsutsa uyenera kufanana ndi kachulukidwe kameneka. Ngati mtengo wotsutsa uli wochepa kwambiri, kachulukidwe kameneka kakhoza kukhala kochuluka kwambiri, kuchititsa waya wotsutsa kutenthedwa kapena ngakhale kutentha. M'malo mwake, kukana kwambiri kungayambitse kuchepa kwa mphamvu zamakono komanso kutaya mphamvu kosakwanira. Chifukwa chake, ndikofunikira kusankha milingo yoyenera yokana kutengera zomwe mukufuna kugwiritsa ntchito.

2. Ganizirani za chitetezo: Pofuna kuonetsetsa kuti waya wotsutsa akuyenda bwino, nthawi zambiri chitetezo chimayambitsidwa powerengera katundu wa pamwamba. Kukula kwa chitetezo chachitetezo kumadalira malo enieni ogwiritsira ntchito, ndipo nthawi zambiri amalangizidwa kuti akhale pakati pa 1.5 ndi 2. Mtolo womaliza wa pamwamba ukhoza kupezedwa mwa kuchulukitsa chitetezo ndi chiwerengero chowerengedwa chamakono.

3. Samalani ndi mphamvu ya kutentha pa mtengo wotsutsa: Mawaya otsutsa amatulutsa kutentha panthawi yogwira ntchito, zomwe zimapangitsa kuti kutentha kuchuluke. Izi zidzapangitsa kusintha kwa mtengo wotsutsa wa waya wotsutsa. Choncho, powerengera katundu wamtunda, m'pofunikanso kuganizira za kusiyana kwa mtengo wotsutsa ndi kutentha. Kawirikawiri, kutentha kwa kutentha kwa zipangizo zotsutsa kungagwiritsidwe ntchito powerengera kukonzanso.

Mwachidule, kuwerengera katundu wamtundu wa waya wotsutsa kumafuna choyamba kudziwa kachulukidwe kameneka, ndiyeno kudziwa katundu womaliza pamwamba pazifukwa monga chitetezo ndi kukonza kutentha. Kuwerengera koyenera kwa katundu wapamtunda kumatha kuonetsetsa kuti mawaya okana akugwira ntchito bwino ndikuwongolera moyo wawo wautumiki.

Ndikoyenera kudziwa kuti zomwe zili pamwambazi ndi njira yokhayo yowerengera katundu wamtunda ndipo sizigwira ntchito pazochitika zonse. Kwa mawaya otsutsa omwe ali ndi zofunikira zapadera, monga zomwe zimagwiritsidwa ntchito m'madera ena otentha kwambiri, njira zowerengera zapadera zingafunikire kugwiritsidwa ntchito malinga ndi zochitika zinazake. Muzogwiritsira ntchito, tikulimbikitsidwa kukaonana ndi akatswiri kapena kutchula miyezo yoyenera yowerengera ndi kusankha.

Mukamagwiritsa ntchito mawaya otsutsa, kuwonjezera pa kuwerengera moyenera katundu wamtunda, mfundo zotsatirazi ziyenera kudziwidwa:

1. Kutentha kwabwino kwa kutentha: Mawaya otsutsa amatulutsa kutentha panthawi yogwira ntchito, choncho m'pofunika kuonetsetsa kuti kutentha kwabwino kumapangitsa kuti pasakhale zolakwika kapena zowonongeka chifukwa cha kutentha kwakukulu.

2. Pewani kuchulukirachulukira: Waya wotsutsa uyenera kugwiritsidwa ntchito mkati mwa kuchuluka kwa katundu wake kuti apewe kuchulukirachulukira komwe kumadutsa, kuti tipewe kuchulukitsitsa kungayambitse mavuto monga kutenthedwa ndi kutenthedwa.

3. Kuyendera nthawi zonse: Yang'anani nthawi zonse momwe ntchito ikugwirira ntchito ndi kugwirizana kwa waya wotsutsa kuti muwonetsetse kuti ikugwira ntchito bwino, ndikukonza mwamsanga kapena kusintha mavuto aliwonse omwe apezeka.

4. Chitetezo cha chilengedwe: Mawaya osagwira ntchito nthawi zambiri amafunika kugwira ntchito pamalo owuma, osawononga mpweya kuti asawonongeke ndi waya wotsutsa.

Mwachidule, kuwerengera molondola kuchuluka kwa waya wotsutsa ndikofunikira kwambiri pakuwonetsetsa kuti ntchito yake ikuyenda bwino komanso moyo wautumiki. Muzogwiritsira ntchito, m'pofunika kusankha miyeso yoyenera yokana kutengera zofunikira zenizeni ndi malo, ndikuwerengera mogwirizana ndi chitetezo ndi kukonza kutentha. Panthawi imodzimodziyo, chidwi chiyenera kuperekedwanso pazikhalidwe zabwino zowonongeka kutentha, kupewa kuchulukirachulukira, ndi kuyang'anitsitsa nthawi zonse kuti zitsimikizire kugwira ntchito kodalirika kwa waya wotsutsa.
