Ukubuyisela iintambo kwisikhephe akunyanzelekanga ukuba kube yintloko ebuhlungu.Sichaza ubucukubhede bokuphucula inkqubo yombane ye-DC yesikhephe sakho ukuze ithobele imimiselo yamva nje kwaye ihlawule zonke iinkqubela phambili zetekhnoloji zakutsha nje.
Uqhagamshelo olulambathayo ngoyena nobangela uxhaphakileyo wokusilela kombane ebhodini. Qinisekisa ukuba zonke iitheminali zicocekile, ziqhagamshelwe ngokukhuselekileyo, kwaye iintambo ezimeleneyo zikhuselekile ngokufanelekileyo.Ityala: Duncan Kent
Ukufakwa kwakhona kweentambo yimfuneko kuyo nayiphi na i-yacht ethe yagcina iingcingo zayo zantlandlolo ngaphezulu kweminyaka engama-20, ngakumbi ukuba unomdla wokuphepha iingxaki ezingapheliyo, ukulungisa iingxaki rhoqo kunye nokulungiswa kwexeshana.
Kumashumi ambalwa eminyaka adlulileyo, abanini beenqanawa ngokubanzi babeneemfuno ezincinci zombane, kunye neendawo zeenqanawa ezibonelela kuphela ngofakelo olusisiseko.
Namhlanje, nangona kunjalo, abanini bamaphenyane babonakala befuna umgangatho ofanayo wezixhobo ebhodini njengoko besonwabela ekhaya, nto leyo edla ngokufuna ukuphinda kucingisiswe ngenkqubo yombane yesikhephe, ukusuka kwiibhetri ukuya kwisixhobo, kunye nokuphuculwa okunzulu kwintambo kunye nokhuseleko lwesekethe.
Xa uphinda udibanisa isikhephe sakho, ukukhetha intambo efanelekileyo yomsebenzi yenye yezona zinto zibalulekileyo, njengoko abaqhubi abancinci banokutshisa kakhulu phantsi komthwalo, okwenza ingozi yomlilo eyingozi.
Ukuguquguquka kwemisonto kuhlawulela nakuphi na ukuhamba okanye ukungcangcazela okuqhelekileyo kweenqanawa elwandle, kwaye i-tinning ikhusela iingcingo zobhedu kwi-oxidation, ehlala ikhokelela ekuxhasweni okwandisiweyo kunye noqhagamshelwano olungalunganga.
Ubushushu be-Ambient bukwanyusa ukuxhathisa kwentambo, ngoko ke amandla akhoyo okuthwala intambo esebenza kwindawo ye-injini ayancipha.
Ngenxa yesi sizathu, kufuneka zibe nomthamo omkhulu kwaye zigqunywe nge-fuel-resistant, i-flame-retardant insulation.
Iintambo zichazwe kwindawo yazo ye-cross-sectional (CSA), kungekhona ubukhulu okanye ububanzi (nangona zombini zihlobene).
Isixhobo sokukhusela isiphaluka esifana ne-60A yokusika i-thermal sithintela intambo ukuba ingalayishwa ngaphaya komda wayo wangoku.Ityala: Duncan Kent
Kwiinkqubo ezininzi ezingabalulekanga, ukuhla kwe-voltage ye-10% kuthathwa njengento eyamkelekileyo, kodwa kwizixhobo ezisisiseko ezifana nerediyo kunye nezixhobo zokuhamba, ukuhla kwe-voltage ye-3% kuyanqweneleka.
Isilingo ngokuqhelekileyo kukusebenzisa intambo encinci, engabizi kakhulu ukudibanisa kwi-bow thruster okanye i-windlass kunye nobude besikhephe.
Nangona kunjalo, ukuba i-CSA incinci kakhulu kubude obufunwayo, i-voltage kwisixhobo iya kuhla kakhulu.
Oku akugcini nje ukunciphisa isixhobo, kodwa kwandisa ikhoyo ngoku etsalwa ngekhebula ngenxa yomthetho ka-Ohm.
Ukuba lo msinga ugqitha igeyiji yekheyibhile ebekiweyo ngoko kunokwenzeka ukuba inyibilike kwaye iqalise umlilo.
Kwiintambo ezinika amandla izixhobo ezininzi ezahlukeneyo, kuya kufuneka ubale obona buninzi bangoku obunokuhamba kunye nazo zonke izixhobo zivuliwe ngokupheleleyo, uze wongeze ukhuseleko olulungileyo/umda wokwandisa wama-30%.
Ukubala umthwalo opheleleyo wangoku kwikhebula ngalinye kwi-amperes (A), ulwahlule amandla esixhobo (kwi-watts (W)) nge-voltage yesiphaluka (V) .Kufuneka kwakhona uqikelele ubude besiphaluka bubonke ngokuchanekileyo ngokunokwenzeka, onokuthi uqikelele ukuba ubude besiphaluka buphelele . iya kuba sisimbuku semigama ukusuka kumthombo wamandla ukuya kwisixhobo kunye nomva.
Kumngeni wezibalo, kukho iiwebhusayithi ezininzi kunye nee -apps ezibonelela ngezixhobo zokubala ezilula zocingo, kungenjalo bona ibhokisi yethu yokubala ubungakanani bocingo (ngezantsi).
Kwimeko-bume enetyuwa enjalo, kunyanzelekile ukuba kuqinisekiswe ukuba zonke iintambo zokuvala zicocekile, ziqhagamshelwe ngokukhuselekileyo, kwaye iintambo ezimeleneyo zikhuselekile ngokufanelekileyo.
Eyona ndlela ilungileyo yokuphelisa iintambo ezininzi kukusebenzisa ibusbar esemgangathweni (iiLwandle eziBlue okanye ezifanayo) kunye neeterminal cable crimp.
Ngaphambi kokuba uqalise ii-wiring, kufuneka uthenge ii-wire cutters ezisemgangathweni, ii-strippers kunye ne-crimpers.
Umsiki ofanelekileyo uya kwenza isikweri esilinganayo ukuze ucingo lutyise yonke indlela ukuya kwi-terminal ye-crimp.
Thenga i-wire stripper ethe yafa iphawulwe ngesayizi nganye yentambo ukuqinisekisa ukuba ufumana intambo ekhutshiweyo ecocekileyo ngaphandle kokuphulukana nayo nayiphi na imicu emihle.
Okokugqibela, i-racheting, i-double-acting, i-parallel-jaw crimpers ibonisa ukufa okubini (icala elinye lokunciphisa uxinzelelo-ukunciphisa umaleko wangaphandle wentambo kunye nelinye icala lokukrazula iingcingo ezingenanto), ukuqinisekisa ngokuchanekileyo kunye nokusebenzisa i-crimper Compress. i-terminal kwaye ucinezele intambo ngokuqinileyo kwikhonkco ngelixa uqinisekisa ukuba yonke into ebalulekileyo yokugquma ihlala injalo.
Qaphela, nangona kunjalo, ukuba kukho iindidi ezimbini ezahlukeneyo "zemihlathi ephindwe kabini" - enye yeyee-crimp ze-heat seal kunye nenye yeyoncedo olulula lwe-strain insulated crimp terminals.

UPaul Tinley uthetha ngamava awothusayo ombane kwiBeneteau 393 Blue Mistress yakhe kunye namabango e-inshurensi alandelayo.
Kwabaninzi oomatiloshe, ukufumana izixhobo ezisebenza ngamandla ezisebenzisa amandla amancinci yinxalenye ephambili yesigqibo sethu…
Kungenjalo, unokufaka igrisi ye-silicone kwisidibanisi sonke phambi kokusebenzisa ukushwabana kobushushu obuwela isinxibelelanisi ngokwaneleyo (umzekelo, ukuba usebenzisa isidibanisi sempundu ukudibanisa iintambo ezimbini, ubuncinci be-25mm kwicala ngalinye).
Xa utywina, sebenzisa isibhamu sokushisa kwindawo ephantsi kakhulu, njengoko ukufudumeza ngokukhawuleza kunokubangela ukuba i-adhesive ibe ne-foam kwaye idale iipokotshi zomoya kwi-joint.
Ungaze uthengise i-crimp okanye i-terminal kwisikhephe, njengoko iya kunyanga intambo yokubopha, iyenze ikhonkco lingabi bhetyebhetye kwaye ke ngoko kunokwenzeka ukuba lichetywe ngokushukuma rhoqo okanye ukungcangcazela.
Ngaphezu koko, kwimeko yomthwalo ogqithisileyo, intambo inokufudumeza ngokwaneleyo ukuba i-solder inyibilike kwaye ucingo luvele luphume kwi-splice, emva koko lunokuthi lufutshane luye kwenye i-terminal okanye i-metal case.
Kwizifakelo zecrimp ezinganyangekiyo, iitheminali mazilinganiswe ukuze zilingane intambo kunye nestud kwaye kukhethwa ukuba zihambelane ngombane nombindi wocingo - oko kukuthi itheminali yobhedu enkonkxiweyo (kungekhona i-aluminiyam) ukuya kwintambo yobhedu enkonkxiweyo.
Hlala ubeka iitheminali zeringi ngokuthe ngqo kwii-studs, kungekhona kwi-washers, oku kuvumela ukufuma kunye nokungcola ukuba kungene kwi-joint, kubangela ukuba umdibaniso ushushu ngokugqithisileyo ngenxa yokwanda kokuchasana.
Ukuba ngesizathu esithile awukwazi ukusikrazula isinxibelelanisi, sebenzisa umgangatho olungileyo weclip-kwibhloko yetheminali (efana neWago), egcinwe kwibhokisi yeplastiki etywiniweyo.
Ukuba ngokuqinisekileyo kufuneka usebenzise iplastiki, ebizwa ngokuba ziibhloko zokugcina isitayile "ibhloko yetshokholeyithi", ke qiniseka ukuba iintonga kunye nezikrufu zilubhedu okanye intsimbi engenasici, kwaye usebenzise igrisi ye-silicone kwiibhloko, kungenjalo ziya kugqwala.
Okokugqibela, qinisekisa ukuba zonke iintambo zibotshelelwe ngokukhuselekileyo kufutshane neetheminali, kwaye ufake iringi yokuthontsiza kwintambo nganye phakathi kwendawo ye-ankile kunye nebhloko yetheminali okanye isixhobo sokugcina amanzi angangeni kwindawo.
Ngokwenza iintambo zephaneli, khumbula ukushiya ikhebula esecaleni eyaneleyo kwisixhobo sokuluka ukuze kube lula ukususwa kwephaneli kunye nokuphatha - awusayi kuzisola!
Gcina iingcingo zikude kangangoko kunokwenzeka. Ukuba akunakuthintelwa, sebenzisa iintsimbi zokuvala ubushushu okanye utywine nayiphi na intsimbi okanye umcu wetheminali kwindawo engangeni manzi.
Emva kokuba uqulunqe i-wiring layout kwaye ukhethe ubungakanani bekhebula, isinyathelo esilandelayo kukufumanisa indlela efanelekileyo yokukhusela i-wiring kwiisekethe ezimfutshane kunye nokugqithisa, kunye nokugqiba indlela yokuvula nokuvala isiphaluka.
Olona phuculo luluncedo olunokuthi lwenziwe kwisistim yombane yeyacht kukuphucula indawo yokutshintsha, ngakumbi ukuba izinto zombane ezingaphezulu zongeziweyo ekuhambeni kweminyaka.
Ngelixa iiswitshi ezilula zokuguqula kunye neefuse zekhatriji zisebenza ukuya kuthi ga kwinqanaba, bahlala bebonisa iingxaki zabo ngenxa yokubola kunye nokukhulula iitheminali zabo ngokuhamba kweminyaka.
Abanini bamaphenyane baya befaka izixhobo ezilambele umbane ngakumbi, eziquka iifriji, iiglasi zomoya, ii-thruster, ii-inverters, izifudumezi zokuntywila, iijenereyitha zamanzi, kwanezipholile-moya, ngoko ke kunyanzelekile ukuba kuqinisekiswe ukuba iintambo zezi zixhobo zinamandla amakhulu zikhuselekile ngokupheleleyo.
Iphuzu elibalulekileyo lokukhumbula xa ufaka isixhobo sokukhusela isiphaluka (CPD) kwikhebula kukuba injongo yalo kukuthintela ikhebula ukuba lilayishwe ngaphaya komda walo wangoku ocetyiswayo.
Ukuzoba umzobo omninzi kakhulu ngentambo kunokubangela ukuba intambo ibeshushu kakhulu, inyibilike i-insulation, kwaye mhlawumbi ibangele nomlilo.
I-CPD inokuthatha ifom ye-fuses okanye i-circuit breakers (CBs), leyo yokugqibela apho abaninzi bakhetha ukukhululeka kunye nokuchaneka kokuphulwa.
I-fuses yomthwalo ophezulu, njenge-ANL (35-750A), i-T-Class (1-800A), kunye neentlobo ze-MRBF (30-300A), zilungele ukutsala okuphezulu kwangoku kunye nokukhuselwa kwebhetri, ngelixa lisebenza ngokukhawuleza, liphantsi-langoku. iifuse zikulungele ngcono Ikhusela ii-electronics ezithambileyo njengoko i-CB ingafumaneki ku-5A.
