Hauv thaj teb ntawm qis - voltage hluav taws xob, ntau yam kev lag luam, thiab tau ua cov khoom lag luam tooj liab, thiab siv hluav taws xob tsis tu ncua, thiab siv hluav taws xob me me, thiab lwm yam xwm txheej. Txawm li cas los xij, yog tias siv cov khoom tsis raug, nws tuaj yeem ua rau cov khoom ua tsis ua tiav, lossis txawm ua rau lub luv luv, to thiab hluav taws kub. Kab lus no yuav tsoo txoj kev siv tau raug ntawm RVS cabs cables, pab koj zam kev tsis to taub.
Thawj kauj ruam: Xaiv txoj cai RVS txoj cai cable, kev nyab xeeb raws li "lub hauv paus"
Cov xwm txheej sib txawv muaj cov kev xav tau sib txawv uas yuav tsum muaj rau kev ua tau zoo ntawm RVs cables. Xaiv tus qauv cai yog tus yuam sij kom tsis txhob muaj kev nyab xeeb kev nyab xeeb. Tsom ntsoov rau cov 3 hauv qab no qhov ntev:
1. Cov khoom siv: cov khoom thiab hla- ntu ntu txiav txim "nqa muaj peev xwm"
Xaiv cov tooj liab ntshiab, thiab yuav ceev faj ntawm tooj liab - clad aluminium cig thiab tooj liab {{txiv clad aluminium (CCA). Ntshiab ceev tooj muaj cov siab ua haujlwm, qis tsis kam, thiab yog resistant rau oxidation, haum rau nruab nrab lub tshuab hluav taws xob tam sim no xws li cua txias thiab cua sov; CCA muaj tus nqi ntawm tsuas yog 60% -} 70% ntawm cov kiv cua tsis tshua muaj zog, thiab muaj zog me me (muaj zog rau 500W).
Tus ntoo khaub lig-} ntu ntu ntawm tus kws saib xyuas (chav ntsuas: mM²) ncaj qha txiav txim siab qhov muaj peev xwm ntau tshaj li lub peev xwm uas muaj peev xwm ua tau ntau yam. Rau cov xwm txheej hauv tsev, xaiv raws li hauv qab no:
0.75-1.0mm²: haum rau LED Downlights, ci nthab teeb, thiab teeb pom kev ncig rau cov chaw (xws li txaj hav zoov rau lub teeb);
1.5-2.5mm²: Siv rau lub tshuab ntswj (xov tooj txawb them, laptop fais fab mov) thiab cov khoom siv me me (muaj zog tsawg dua lossis sib npaug);
Tsis txhob siv cov xaim ntawm 0.75mm² lossis me dua los txuas cov khoom siv hluav taws xob siab (xws li cov txheej txheem hluav taws xob (xws li cov txheej txheem hluav taws xob kom yaj kom yaj.
2. Rwb thaiv txheej txheej: cov chaw sib txawv yuav tsum muaj cov khoom sib txawv
Lub rwb thaiv tsev txheej ntawm rvs cables yog muab faib ua PVC (polyvinyl chloride) thiab xlpe (hla}}}}- txuas Polyethylene). Xaiv raws li kev siv kev pab:
PVC Rwb thaiv tsev: Xav txog PVC rau cov chaw ua haujlwm sab hauv thiab chav ua noj thiab chav ua noj kom zoo, thiab ze rau cov chav dej thiab cov pa dej siab, thiab tej zaum yuav muaj kev pheej hmoo ntau dhau sijhawm.
XLPE rwb thaiv tsev: Nyiam rau noo / siab {degring vajsab txheej (PVC tsuas yog siv hluav taws xob ua si) Ib lub neej kev pab ntau dua li PVC rwb thaiv tsev los ntawm 3-5 xyoos.
3. Paub meej tias lub teb chaws tus qauv, zam "{-} Tsis muaj cov khoom lag luam"
Thaum kev yuav khoom, nco ntsoov xaiv cov khoom lag luam uas ua raws li GB / T 5023 (Suav teb chaws) lossis IEC 60227 (Tus Txheej Txheem Thoob Ntiaj Teb), thiab tsom rau kev kuaj xyuas 3 cov ntsiab lus:
Qhov saum npoo ntawm cov rwb thaiv tsev txheej tau pom cov cim ntshiab: suav nrog hom, cov khoom siv rwb thaiv tsev (xws li "GB / T 5023.5");
Lub thickness ntawm rwb thaiv tsev txheej yog niaj hnub: tsis muaj pob txha tsis pom tseeb thaum pinched los ntawm tus neeg kos npe "tshwm sim tom qab tev;
Tus thawj coj tau hloov pauv tau zoo: tom qab dabtsi yog li 10 lub sij hawm, lub coppil hlau tsis tawg, thiab yuav muaj "cov plaub hau dawb {2} Kuv zoo li" tawg tom qab khoov).
Qhov thib ob kauj ruam teeb tsa: 5 cov kauj ruam tseem ceeb kom tsis txhob muaj 90% ntawm kev ua txhaum kev txhim kho tsis raug yog lub ntsiab tseem ceeb ntawm RVS Cable Ua tsis tiav, tshwj xeeb yog rau DIY hauv tsev. Thov nruj ua raws cov txheej txheem hauv qab no:
1. Npaj cov cuab yeej: Ua kom muaj kev nyab xeeb nrog cov cuab yeej tshaj lij
Cov Cuab Yeej Siv Yuav Tsum:
Cov neeg (zam kev siv cov txiab lossis hluav taws xob riam, vim tias lawv tuaj yeem khawb cov qauv yooj yim);
Hla / Ca -} taub hau ntsia hlau (nws pom zoo kom cov neeg uas insulated los tiv thaiv hluav taws xob);
Insulating daim kab xev (xaiv Flame - retardant hom, nrog rwb thaiv tsev zoo dua);
Multivation (siv rau kev sim ntsuas thiab rwb thaiv tsev tsis kam);
Cov hnab looj tes xuas tes ua (hnav thaum lub sij hawm xaim, tshwj xeeb tshaj yog thaum ua haujlwm tsis muaj hwj chim tawm).
2. Sawb cov xaim: Qhov ntev, tsis muaj kev ua phem rau lub tooj liab hlau
Siv cov hlau stripper mus clamp lub cable kawg, tig maj mam muab thiab rub tawm sab nraud mus rau strip 5-8mm ntawm sab nraud twisting txheej;
Cais tawm sab hauv cov khaubncaws sab nraud ntawm cov txheej txheem ntawm ob tus neeg ua haujlwm, nrog kev tswj kav ntev ntawm 2-3 xyoos (luv heev yuav nthuav tawm lub tooj liab hlau, luv heev ua rau nws nyuaj rau txuas);
Tom qab stripping cov xaim xaim, khij lub xaim tooj liab: yog tias muaj ib qho kev tawg, tawg} strip cov hlau (tawg ntawm cov hlau tooj liab kom tsis txhob loosening.
3. Txuas: Tiv thaiv kev loosening thiab luv luv yog tus tseem ceeb
Kev sib txuas lus tsis zoo (hloov pauv): Ntxig cov xov tooj liab mus rau hauv lub davhlau ya nyob twg, kov cov ntsia hlau nrog rau lwm tus neeg saib xyuas yuav ua rau muaj kev luv nqi); Yog tias lub davhlau ya nyob twg yog "vuam hom", siv lub pob txha hlau mus nias, zam kev tsis tseeb.
CABLE txuas (txuas ntxiv hluav taws xob): tib lub ntsej muag zoo nkauj dua 20 hli kev sib koom tes ntau dua lossis sib npaug ntawm 5 hli. Rau kev pab cuam siab dua, ntxiv "kev sib txuas cov chaw sib txuas" kom tsis txhob oxidation thiab loosening ntawm qhov sib txuas lus.
Them nyiaj rau polarity: tsis txhob thim rov qab thiab nyob hlau tsis muaj hluav taws xob thiab cov xaim hluav taws xob rau hauv cov xaim hluav taws xob, tshwj xeeb nws yuav ua rau cov khoom siv hluav taws xob, tshwj xeeb rau cov khoom siv hlau xws li Tub yees thiab cov tshuab ntxhua khaub ncaws, qhov pheej hmoo siab dua.
4. Kab hlau: Zam kev phom sij, kho kom khov kho
Kev siv hluav taws xob sab hauv: khiav raws phab ntsa, tsis txhob zais cov phom sij: cable yog nteg nrog phab ntsa lossis qab nthab, tas li nrog xaim clips (ncua 30-50cm los tiv thaiv sagging); Tsis txhob faus cov cable hauv qab cov ntaub pua plag lossis hauv cov rooj tog (siab yuav ua rau cov kav dej sib dhos lossis cov pa roj cua tsis tuaj yeem tshwm sim los ntawm kev phom sij lossis roj to).
Cais cov siab thiab qis dua voltage: anti {{0} {{} {} {} {{} {square cable rau dej Tso cua sov) yuav tsum yog tsawg kawg yog 10Cm sib nrug kom tsis txhob cuam tshuam los ntawm cov xim hluav taws xob high-voltage sib xyaw vim muaj kev laus txheej txheej.
Cov phom sij / sab nraum zoov: Ntxiv cov Tsho Waterproof Tsho: Rau chav dej thiab sab nraum zoov garden teeb, los tiv thaiv dej thiab noo los ntawm kev pom; Tsis txhob faus cov cable ncaj qha hauv qab av (tsis muaj kev tiv thaiv, nws yog nquag rau corrosion thiab nas daim ntawv).
TEST UA NTEJ YUAV TSUM TAU: Siv multimeter rau "kos"
Tom qab cov xaim yog ua tiav, tsis txhob maj rau lub zog rau, siv cov puv los ua 2 qhov kev ntsuas tseem ceeb:
Kev sim txuas ntxiv: Teeb ntau ntau rau "txuas ntxiv", kov tib qho kev sib tw ntawm ob qho, yog tias ib lub suab nrov "tau tawm tswv yim, nws qhia tau tias cov neeg saib xyuas tsis tawg; Rwb thaiv tsev tsis kam ntsuas: Teeb tsa "ntau yam", txuas ib qho kawg rau tus neeg saib xyuas thiab lwm qhov kawg rau cov tawv nqaij sab nraud ntawm lub cable. Qhov tsis kam ntawm PVC cov xaim hluav taws xob yuav tsum muaj ntau dua los yog sib npaug ntawm 0.5 Mω, thiab ntawm XLPE insulting cables txheej, thiab nws yuav tsum tau tshuaj xyuas thiab kho).
Tom qab qhov kev xeem dhau, lub zog ntawm thiab saib seb cov khoom siv ua haujlwm ib txwm ua haujlwm ib txwm; Yog tias muaj kev mus ncig los yog fuse melting, tam sim ntawd txiav tawm lub zog thiab kuaj xyuas cov kab luv luv lossis ntau dua.
Daim Ntawv Thov Kev Ua Si: Cov no tuaj yeem siv tau, thiab cov no yuav tsum tsis txhob siv.
Qhov zoo ntawm rvs clescles pw hauv "lub zog loj, me me fais fab, thiab hloov hluav taws xob me me, tab sis lawv tsis tas ua kom pom tseeb thiab txwv tsis pub muaj ntau yam:
Pom zoo siv cov xwm txheej
Cov xwm txheej nyob ntawm thaj chaw: Cov teeb cig pom kev zoo nkauj (cov khoom siv qab nthab (cov txaj taw tes (cov kab teeb ci, cov routers, cov neeg siv xov tooj txawb);
Cov xwm txheej ua lag luam: LED vaj huam sib luag lub teeb xaim rau hauv chaw ua haujlwm, hluav taws xob rau cov khoom siv hluav taws xob hauv cov khoom siv me me (cov ntawv sau npe me me (thiab lwm yam);
Muaj cov xwm txheej: Kev tswj lub Hoobkas tsim cov kab ke (sensor, relay wire), cov hluav taws xob rau cov roj me (hluav taws xob tsawg dua lossis sib npaug nrog 1 kw).
Txwv tsis pub cov scenarios (tsis txhob "oversep cov ciaj ciam" siv)
High - Cov Khoom Siv Hluav Taws Xob High: Cov Hluav Taws Xob Hluav Taws Xob
Undergle Undera toj roob hauv pes teeb pom kev zoo teeb tsa teeb thiab yuav tsum tau siv cables nrog vv22), RVs tsis muaj kev tiv thaiv thiab muaj kev puas tsuaj;
High -} pa taws ib puag ncig: thaj chaw ze rau kev ua kom sov thiab roj, yuav tsum siv cov roj cua silicone
Kev Txij Nkawm: 3 Phajits Kom Ntev Luj Cable Lub Neej
Kev saib xyuas tseeb tuaj yeem txuas ntxiv cov kev pabcuam lub neej ntawm RVS cabs Cables ntawm 5-8 xyoos thiab txo qhov kev pheej hmoo ntawm kev ua txhaum:
Kev soj ntsuam ib txwm ntawm cov txheej txheem: Tshawb xyuas ib xyoos ib zaug, daj ua si, hloov nws tam sim ntawd (hloov pauv tam sim ntawd (cov laus rwb thaiv tsev txheej yog qhov to taub);
Zam kev siv tshuab: 1.5mm² RVS Cable muaj lub zog ntawm thaj tsam 2200W), tsis txhob ntsaws rau lub zog hluav taws xob (1800W) thiab lub zog hluav taws xob (1800W) thiab lub zog hluav taws xob (1800W)
Tsis txhob "rub" thaum lub rooj tog zaum lossis cov khoom siv txav, tshwj xeeb rub lub rwb thaiv tsev txheej, koj tuaj yeem ua thawj zaug txiav tawm ntawm lub zog thiab tom qab ntawd npaj lub cable.
Thaum kawg: kev nyab xeeb ua ntej, nrhiav kev pab los ntawm cov hluav taws xob rau teeb meem kev tshaj lij.
Txawm hais tias RVS cables yog qhov yooj yim rau kev ua haujlwm, kev nyab xeeb ntawm lub tsev pheebsuab uas muaj tseeb, nws raug nquahu kom tsis txhob muaj kev nyab xeeb los ntawm DIY yuam kev. Tsuav xaiv, kev teeb tsa, thiab kev txij nkawm yog qhov tseeb, RVS cables tuaj yeem dhau los ua kev nyab xeeb tsawg, kev nyab xeeb kev nyab xeeb hluav taws xob txhua hnub siv hluav taws xob txhua hnub.
