Kuwongolera bwato sikuyenera kupweteketsa mutu.Tikukufotokozerani zovuta zokozera makina amagetsi a DC a boti lanu kuti agwirizane ndi malamulo aposachedwa ndikukwaniritsa kupita patsogolo kwaukadaulo kwaposachedwa.
Kulumikizidwe kolakwika ndizomwe zimayambitsa kulephera kwa magetsi m'boti. Onetsetsani kuti materminal onse ndi aukhondo, olumikizidwa bwino, komanso kuti zingwe zoyandikana ndi zotetezedwa bwino.Ndalama: Duncan Kent
Kukonzanso ndikofunikira kwa yacht iliyonse yomwe yasunga mawaya ake oyambira kwazaka zopitilira 20, makamaka ngati mukufuna kupewa zovuta zosatha, kuthana ndi zovuta nthawi zonse komanso kukonza kwakanthawi.
Zaka makumi angapo zapitazo, eni zombo nthawi zambiri anali ndi zofunikira zochepa za magetsi, pomwe malo opangira zombo amangopereka zoikamo zofunika kwambiri.
Masiku ano, eni mabwato akuwoneka kuti akufuna mlingo wofanana wa zida zomwe zili m'bwalo monga momwe amasangalalira kunyumba, zomwe nthawi zambiri zimafuna kuganiziranso za kayendedwe ka magetsi ka boti, kuchokera ku mabatire kupita ku zipangizo, komanso kukonzanso kwakukulu kwa chingwe ndi chitetezo cha dera.
Mukamapanganso bwato lanu, kusankha chingwe choyenera pantchitoyo ndi chimodzi mwazinthu zofunika kwambiri, chifukwa ma conductor ocheperako amatha kutenthedwa ndi katundu, zomwe zimapangitsa kuti pakhale ngozi yowopsa yamoto.
Kusinthasintha kwa zingwezo kumalipira kusuntha kulikonse kapena kugwedezeka kwa zombo zapanyanja, ndipo tinning imateteza mawaya amkuwa ku okosijeni, zomwe nthawi zambiri zimayambitsa kukana komanso kulumikizana kolakwika.
Kutentha kozungulira kumawonjezeranso kukana kwa chingwe, kotero kuti mphamvu yonyamulira ya chingwe yomwe ikuyenda kudzera mu chipinda cha injini imachepetsedwa.
Pachifukwa ichi, ayenera kukhala ndi mphamvu zambiri ndipo aphimbidwe ndi mafuta osagwira mafuta, osagwira moto.
Zingwe zimatchulidwa ndi malo awo ozungulira (CSA), osati makulidwe awo kapena m'mimba mwake (ngakhale ziwirizo zikugwirizana).
Chipangizo choteteza dera monga chodulira chotenthetsera cha 60A chimalepheretsa chingwe kukwezedwa kupyola malire ake omwe alipo.Ndalama: Duncan Kent
M'mapulogalamu ambiri omwe si ofunikira, kutsika kwamagetsi kwa 10% kumaonedwa kuti ndikovomerezeka, koma pazida zoyambira monga mawailesi ndi zida zoyendera, kutsika kwamagetsi kwa 3% ndikofunikira.
Chiyesocho nthawi zambiri chimakhala chogwiritsa ntchito chingwe chaching'ono, chotsika mtengo kuti mulumikizane ndi chopozera uta kapena mphepo yam'mbali kutalika kwa bwato.
Komabe, ngati CSA ndi yaying'ono kwambiri kutalika komwe mukufuna, mphamvu yamagetsi pa chipangizocho idzatsika kwambiri.
Izi sizimangochepetsa chipangizocho, komanso zimawonjezera zomwe zimakokedwa kudzera pa chingwe chifukwa cha lamulo la Ohm.
Ngati mphamvuyi idutsa muyeso wa chingwe chovotera ndiye kuti imatha kusungunuka ndikuyatsa moto.
Pazingwe zomwe zili ndi mphamvu pazida zosiyanasiyana, muyenera kuwerengera kuchuluka kwapano komwe kumatha kuyenda ndi zida zonse zitayatsidwa, kenaka onjezerani malire otetezedwa / owonjezera a 30%.
Kuwerengera kuchuluka kwa katundu panopa pa chingwe mu amperes (A), gawani mphamvu ya chipangizo (mu Watts (W)) ndi voteji dera (V) . Muyeneranso kuyerekezera okwana dera kutalika molondola monga n'kotheka, amene adzakhala kuchuluka kwa mtunda kuchokera ku gwero la mphamvu kupita ku chipangizo ndi kumbuyo.
Pazovuta zamasamu, pali mawebusayiti ambiri ndi mapulogalamu omwe amapereka zowerengera za kukula kwa waya, apo ayi onani bokosi lathu lowerengera kukula kwa waya (pansipa).
M'malo amchere wotere, ndikofunikira kuwonetsetsa kuti zoyimitsa zonse ndi zoyera, zolumikizidwa bwino, ndipo zingwe zoyandikana ndizotetezedwa bwino.
Njira yabwino yothetsera zingwe zingapo ndikugwiritsa ntchito mabasi abwino (Blue Seas kapena zofananira) ndi ma terminals a crimp cable.
Musanayambe kuyatsa, muyenera kugula mawaya abwino, ma strippers, ndi ma crimpers.
Wodula bwino amadula mbali zonse kuti waya azidya mpaka ku crimp terminal.
Gulani chingwe chodulira mawaya chomwe chimafa cholembedwa pa kukula kwa chingwe chilichonse kuti muwonetsetse kuti mumapeza chingwe chovulidwa bwino osataya zingwe zilizonse zabwino.
Pomaliza, ma racheting, ochita kawiri, ophatikizira nsagwada amakhala ndi kufa kwapawiri (mbali imodzi yochepetsera kupsinjika kwakunja kwa chingwe ndi mbali inayo podula mawaya opanda kanthu), kuwonetsetsa kulondola komanso kugwiritsa ntchito crimper Compress the terminal ndikusindikiza chingwe mwamphamvu mu cholumikizira ndikuwonetsetsa kuti zotchingira zonse zofunika zizikhalabe.
Zindikirani, komabe, kuti pali mitundu iwiri yosiyana ya "sagwada ziwiri" - imodzi ya crimp yosindikizira kutentha ndi ina ya crimp terminals yosavuta yopumira.

Kapenanso, mutha kupaka mafuta a silicone pa cholumikizira chonse musanagwiritse ntchito kutentha kwa kutentha komwe kumadutsa cholumikizira mokwanira (mwachitsanzo, ngati mukugwiritsa ntchito cholumikizira chathako kulumikiza zingwe ziwiri, osachepera 25mm mbali iliyonse).
Mukasindikiza, gwiritsani ntchito mfuti yamoto pamalo otsika kwambiri, chifukwa kutentha mwachangu kungapangitse kuti zomatirazo zikhale thovu ndikupanga matumba a mpweya molumikizana.
Osagulitsa crimp kapena terminal m'boti, chifukwa imachiritsa mawaya, zomwe zimapangitsa kuti mgwirizanowo ukhale wosavuta kumeta ndikumeta pafupipafupi kapena kugwedezeka.
Kuphatikiza apo, pakadzaza kwambiri, chingwecho chimatha kutentha kwambiri kotero kuti solder imasungunuka ndipo waya amangotuluka kuchokera pachigamulo, ndiye kuti imatha kupita ku terminal ina kapena chitsulo.
Pazitsulo zokhala ndi crimp zosagwira, matheminali akuyenera kukula kuti agwirizane ndi chingwe ndi zipilala ndipo makamaka zizigwirizana ndi mawaya apakati pa mawaya - mwachitsanzo, cholumikizira chamkuwa (osati aluminiyamu) kupita ku waya wamkuwa wamkuwa.
Nthawi zonse ikani mapiko a mphete mwachindunji pazitsulo, osati pazitsulo, izi zimapangitsa kuti chinyezi ndi zonyansa zilowe mu mgwirizano, zomwe zimapangitsa kuti mgwirizanowo utenthe kwambiri chifukwa cha kuchuluka kwa kukana.
Ngati pazifukwa zina simungathe kudumpha cholumikizira, gwiritsani ntchito cholumikizira chabwino kwambiri (monga Wago), chosungidwa mubokosi lapulasitiki losindikizidwa.
Ngati mwamtheradi muyenera kugwiritsa ntchito pulasitiki, otchedwa "chokoleti chipika" kalembedwe midadada terminals, ndiye osachepera kuonetsetsa ndodo ndi zomangira ndi mkuwa kapena zitsulo zosapanga dzimbiri, ndi ntchito silikoni girisi midadada, apo ayi iwo dzimbiri.
Pomaliza, onetsetsani kuti zingwe zonse ndi zomangika bwino pafupi ndi matheminali, ndipo ikani mphete yodontha mu chingwe chilichonse pakati pa nangula ndi chipika chotsekera kapena chipangizo kuti madzi asalowe mgulu.
Pa mawaya apapanelo, kumbukirani kusiya chingwe chokwanira pacholuka kuti chichotsedwe mosavuta ndikuchigwira - simudzanong'oneza bondo!
Sungani mawaya kutali kwambiri ndi bilge momwe mungathere. Ngati sizingatheke, gwiritsani ntchito zisindikizo za kutentha kapena sungani splice kapena chingwe chotsekera muthumba lamadzi.
Mutatha kupanga mapangidwe a mawaya ndikusankha kukula kwa chingwe, sitepe yotsatira ndiyo kudziwa momwe mungatetezere mawaya ku maulendo afupiafupi ndi olemetsa, komanso kudziwa momwe mungatsegule ndi kutseka dera.
Chimodzi mwazinthu zothandiza kwambiri zomwe zingapangidwe pamagetsi a yacht ndikukweza ma switch panel, makamaka ngati zinthu zamagetsi zambiri zawonjezeredwa pazaka zambiri.
Ngakhale ma switch osavuta osinthira ndi ma fuse a cartridge amagwira ntchito mokulira, nthawi zambiri amabweretsa mavuto awoawo chifukwa cha dzimbiri ndi kumasuka kwa ma terminals awo pazaka zambiri.
Eni mabwato akuwonjezera kuyika zida zanjala zamagetsi, kuphatikiza mafiriji, ma windlasses, ma thruster, ma inverter, mahita omiza, majenereta amadzi, ngakhalenso ma air conditioners, kotero ndikofunikira kuwonetsetsa kuti zingwe za zida zamphamvu kwambirizi ndi zotetezeka kotheratu.
Mfundo yofunika kukumbukira mukamayika chipangizo choteteza dera (CPD) mu chingwe ndikuti cholinga chake ndikuletsa chingwecho kuti chisatengedwe kupitirira malire ake omwe akulimbikitsidwa.
Kujambula mphamvu kwambiri kudzera pa chingwe kungapangitse chingwecho kutenthedwa, kusungunula chotsekereza, ndipo mwinanso kuyatsa moto.
