Rewiring ib lub nkoj tsis tas yuav mob taub hau.Peb piav qhia qhov tsis txaus ntseeg ntawm kev txhim kho koj lub nkoj DC hluav taws xob kom ua raws li cov cai tshiab thiab npog tag nrho cov kev hloov tshiab tshiab.
Kev sib txuas tsis zoo yog qhov feem ntau ua rau hluav taws xob tsis ua haujlwm ntawm lub nkoj.Ua kom txhua lub davhlau ya nyob twg huv si, ruaj ntseg txuas, thiab cov cables uas nyob ib sab tau ruaj ntseg zoo.Credit: Duncan Kent
Rewiring yog qhov tsim nyog rau txhua lub yacht uas tau khaws nws cov kev xaim qub rau ntau tshaj 20 xyoo, tshwj xeeb tshaj yog tias koj xav kom tsis txhob muaj teeb meem tsis tu ncua, kev daws teeb meem tas li thiab kho ib ntus.
Ob peb xyoos dhau los, cov tswv nkoj feem ntau muaj qhov xav tau tsawg kawg nkaus rau hluav taws xob, nrog rau cov chaw nres nkoj tsuas yog qhov yooj yim tshaj plaws installation.
Niaj hnub no, txawm li cas los xij, cov tswv nkoj zoo li xav tau tib theem ntawm cov khoom siv hauv lub nkoj raws li lawv nyiam nyob hauv tsev, uas feem ntau yuav tsum tau rov xav txog lub nkoj tag nrho cov khoom siv hluav taws xob, los ntawm cov roj teeb mus rau cov khoom siv, nrog rau kev hloov kho loj rau kev tiv thaiv cable thiab circuit.
Thaum rewiring koj lub nkoj, xaiv txoj cai cable rau txoj haujlwm yog ib qho tseem ceeb tshaj plaws, raws li cov neeg ua haujlwm tsis zoo tuaj yeem ua rau overheat hauv load, tsim kom muaj kev phom sij txaus ntshai.
Qhov yooj yim ntawm cov strands them nyiaj rau txhua qhov kev txav los yog kev co ntawm cov nkoj hauv hiav txwv, thiab cov tinning tiv thaiv cov xov tooj ntawm oxidation, uas feem ntau ua rau muaj zog tiv thaiv thiab kev sib txuas tsis raug.
Ambient cua sov kuj ua rau kom cov kev tiv thaiv ntawm lub cable, yog li tam sim no-nqa peev xwm ntawm lub cable khiav los ntawm lub cav compartment yog txo.
Vim li no, lawv yuav tsum muaj peev xwm ntau dua thiab raug them nrog roj-resistant, nplaim hluav taws-retardant rwb thaiv tsev.
Cov kab hluav taws xob tau teev tseg los ntawm lawv qhov chaw hla ntu (CSA), tsis yog lawv cov thickness lossis txoj kab uas hla (txawm tias ob qho tib si cuam tshuam).
Ib qho khoom siv tiv thaiv hluav taws xob xws li 60A thermal cutout tiv thaiv lub cable los ntawm kev thauj khoom dhau ntawm nws qhov siab tshaj plaws tam sim no txwv.Credit: Duncan Kent
Nyob rau hauv feem ntau cov ntawv thov tsis tseem ceeb, 10% qhov hluav taws xob poob yog pom zoo, tab sis rau cov khoom siv yooj yim xws li xov tooj cua thiab cov khoom siv navigation, 3% voltage poob yog qhov xav tau.
Qhov kev ntxias no feem ntau yog siv me me, tsis tshua kim cable txuas rau lub hneev thruster lossis windlass raws qhov ntev ntawm lub nkoj.
Txawm li cas los xij, yog tias CSA tsawg dhau rau qhov xav tau ntev, qhov hluav taws xob thoob plaws lub cuab yeej yuav poob qis heev.
Qhov no tsis tsuas yog ua rau lub cuab yeej ua kom qeeb, tab sis kuj nce qhov tam sim no rub los ntawm cable vim Ohm txoj cai.
Yog tias qhov tam sim no tshaj qhov ntsuas kab ntsuas ntsuas, nws yuav zoo li yaj thiab pib hluav taws.
Rau cov kab hluav taws xob uas siv hluav taws xob ntau yam sib txawv, koj yuav tsum xam qhov siab tshaj plaws tam sim no uas tuaj yeem ntws nrog txhua yam khoom siv tag nrho, tom qab ntawd ntxiv qhov kev nyab xeeb zoo / txuas ntxiv ntawm 30%.
Txhawm rau xam tag nrho cov khoom tam sim no ntawm ib lub cable hauv amperes (A), faib lub zog ntawm lub cuab yeej (hauv watts (W)) los ntawm qhov hluav taws xob Circuit Court (V). yuav yog tus lej ntawm qhov kev ncua deb ntawm lub zog mus rau lub cuab yeej thiab rov qab.
Rau qhov kev sib tw lej, muaj ntau lub vev xaib thiab cov ntawv thov uas muaj cov tshuab xam zauv yooj yim hlau loj, txwv tsis pub saib peb lub npov hlau loj (hauv qab).
Nyob rau hauv xws li ib puag ncig qab ntsev, nws yog ib qho tsim nyog yuav tsum xyuas kom meej tias txhua qhov kev txiav tawm yog huv si, ruaj ntseg txuas, thiab cov cables uas nyob ib sab tau ruaj ntseg zoo.
Txoj hauv kev zoo tshaj plaws los txiav ntau cov cables yog siv cov busbar zoo (Blue Seas lossis zoo sib xws) thiab crimp cable terminals.
Ua ntej koj pib xaim, koj yuav tsum tau yuav cov hlau cutters zoo, strippers, thiab crimpers.
Ib tug dlej cutter yuav ua ib tug txawm square txiav kom cov hlau txau tag nrho txoj kev mus rau hauv lub crimp davhlau ya nyob twg.
Yuav cov hlau stripper uas tau tuag cim rau txhua qhov loj me los xyuas kom meej tias koj tau txais cov hlua khi kom huv si yam tsis muaj kev poob zoo.
Thaum kawg, lub ratcheting, ob-acting, parallel-puab puab tsaig crimpers feature dual tuag (ib sab rau kev ntxhov siab-relieving txheej txheej ntawm lub cable thiab lwm sab rau crimping lub liab qab xov hlau), kom ntseeg tau tias yog thiab txawm daim ntawv thov ntawm crimper Compress lub davhlau ya nyob twg thiab nias lub cable kom ruaj khov rau hauv lub connector thaum ua kom paub tseeb tias tag nrho cov rwb thaiv tsev tseem ceeb tseem nyob tsis zoo.
Nco ntsoov, txawm li cas los xij, muaj ob hom "ob lub puab tsaig" sib txawv - ib qho rau cov cua sov foob crimps thiab ib qho rau yooj yim strain nyem insulated crimp terminals.

Rau cov neeg tsav nkoj feem ntau, nrhiav cov cuab yeej siv hluav taws xob uas siv lub zog tsawg kawg yog qhov tseem ceeb ntawm peb qhov kev txiav txim siab…
Xwb, koj tuaj yeem thov cov roj silicone rau tag nrho cov khoom sib txuas ua ntej siv cov cua sov uas sib tshooj ntawm cov khoom sib txuas kom txaus (xws li, yog siv lub taub qab txuas rau ob lub cables, tsawg kawg 25mm ntawm txhua sab).
Thaum sib khi, siv rab phom cua sov ntawm qhov chaw qis tshaj plaws, vim tias cua sov sai heev tuaj yeem ua rau cov nplaum nplaum ua npuas ncauj thiab tsim cov hnab ntim cua hauv qhov sib koom ua ke.
Tsis txhob solder lub crimp lossis lub davhlau ya nyob twg ntawm lub nkoj, vim nws yuav kho cov hlua khi, ua rau kev sib koom ua ke tsis yooj yim dua thiab yog li yuav raug txiav los ntawm kev txav los yog kev co.
Dab tsi ntxiv, nyob rau hauv qhov xwm txheej dhau los, cov kab hluav taws xob tuaj yeem ua kom sov txaus kom cov hlau yaj thiab cov hlau tsuas yog poob ntawm qhov sib txuas, ces nws tuaj yeem luv luv mus rau lwm lub davhlau ya nyob twg lossis rooj plaub hlau.
Rau kev tiv thaiv tsis muaj crimp fittings, cov terminals yuav tsum loj kom haum rau cov cable thiab stud thiab nyiam dua yog hluav taws xob sib xws nrog cov tub ntxhais hlau - piv txwv li tinned tooj liab davhlau ya nyob twg (tsis yog txhuas) rau tinned tooj liab hlau.
Ib txwm tso lub nplhaib terminals ncaj qha rau ntawm cov pob zeb, tsis yog ntawm cov tshuab ntxhua khaub ncaws, qhov no tso cai rau cov dej noo thiab cov kab mob nkag mus rau hauv kev sib koom ua ke, ua rau kev sib koom ua ke dhau los vim muaj zog tiv thaiv.
Yog tias vim li cas koj yeej tsis tuaj yeem crimp lub connector, siv qhov zoo zoo clip-on davhlau ya nyob twg thaiv (xws li Wago), nyob rau hauv ib lub hnab yas kaw.
Yog tias koj yuav tsum siv cov yas, hu ua "chocolate block" style terminal blocks, ces tsawg kawg yog xyuas kom cov pas nrig thiab cov ntsia hlau yog tooj dag lossis stainless hlau, thiab siv cov roj silicone rau cov blocks, txwv tsis pub lawv yuav corrode.
Thaum kawg, xyuas kom tag nrho cov cables tau ruaj khov nyob ze ntawm lub terminals, thiab ntxig ib lub nplhaib rau hauv txhua lub cable ntawm qhov taw tes thauj tog rau nkoj thiab lub davhlau ya nyob twg thaiv lossis cov cuab yeej kom tsis txhob muaj dej tawm ntawm qhov sib koom ua ke.
Rau vaj huam sib luag thaiv, nco ntsoov tso cov khoom seem txaus ntawm lub loom kom yooj yim tshem tawm vaj huam sib luag thiab tuav - koj yuav tsis khuv xim nws!
Khaws cov xov hlau kom deb ntawm lub bilge raws li qhov ua tau.Yog tias tsis tuaj yeem zam tau, siv cov khoom siv hluav taws xob kub hnyiab los yog muab cov hlua khi lossis cov hlua khi rau hauv cov ntaub ntawv tsis muaj dej.
Tom qab koj tau tsim cov txheej txheem thaiv thiab xaiv cov cable loj, cov kauj ruam tom ntej yog los txiav txim siab seb yuav tiv thaiv cov kab hluav taws xob zoo li cas los ntawm cov kab hluav taws xob luv luv thiab overloads, thiab txiav txim siab yuav qhib thiab kaw qhov hluav taws xob li cas.
Ib qho kev txhim kho tseem ceeb tshaj plaws uas tuaj yeem ua rau lub yacht lub tshuab hluav taws xob yog kev hloov kho vaj huam sib luag, tshwj xeeb tshaj yog cov khoom siv hluav taws xob tau ntxiv rau ntau xyoo.
Txawm hais tias qhov yooj yim toggle keyboards thiab cartridge fuses ua haujlwm rau ib qho twg, lawv feem ntau nthuav tawm cov teeb meem ntawm lawv tus kheej vim yog corrosion thiab loosening ntawm lawv cov terminals ntau xyoo.
Cov tswv ntawm lub nkoj tab tom txhim kho ntau lub zog tshaib plab, nrog rau cov tub yees, cua txias, thrusters, inverters, immersion heaters, water generators, and even air conditioners, yog li nws yog ib qho tseem ceeb kom ntseeg tau tias cov cables rau cov khoom siv hluav taws xob siab no muaj kev nyab xeeb tag nrho.
Lub ntsiab lus tseem ceeb uas yuav tsum nco ntsoov thaum txhim kho cov cuab yeej tiv thaiv hluav taws xob (CPD) hauv ib lub cable yog tias nws lub hom phiaj yog los tiv thaiv cov cable los ntawm kev thauj khoom dhau ntawm nws qhov siab tshaj plaws tam sim no txwv.
Kev kos cov tam sim no ntau dhau los ntawm lub cable tuaj yeem ua rau lub cable overheat, yaj lub rwb thaiv tsev, thiab tej zaum kuj ua rau hluav taws.
CPDs tuaj yeem siv cov fuses lossis Circuit Court breakers (CBs), tom kawg uas ntau tus xaiv kom yooj yim thiab raug qhov tseeb.
High-load fuses, xws li ANL (35-750A), T-Class (1-800A), thiab MRBF (30-300A) hom, yog qhov zoo tagnrho rau kev rub tawm tam sim no thiab roj teeb tiv thaiv, thaum ua haujlwm ceev, tsis tshua muaj tam sim no fuses zoo dua rau Tiv thaiv cov khoom siv hluav taws xob zoo li CB tsis muaj nyob ntawm 5A.
