2.5mm2 tooj liab tub ntxhais hlau thiab cov hlau tsaus tuaj yeem tiv taus qhov hluav taws xob siab tshaj plaws ntawm 4000 watts, thiab 6mm2 tooj liab tub ntxhais hlau tuaj yeem tiv taus hluav taws xob tsawg dua 7500 watts. Thiab ob lub 2.5mm2 tooj liab core xov hlau txuas ua ke, theoretically, lawv tuaj yeem tiv taus hluav taws xob hauv 8000 watts. Tab sis qhov no tsuas yog ib qho theoretical speculation. Hauv kev siv tiag tiag, nws yog qhov zoo tshaj plaws los siv nws li 4mm2 tooj liab tub ntxhais hlau, uas yog, thaum tso cov xov hlau qhib, lub zog ntawm cov khoom siv hluav taws xob yog tswj tsis pub dhau 7200 watts, thiab thaum tso cov xov hlau tsaus, qhov siab tshaj plaws ntawm cov khoom siv hluav taws xob tswj tau. nyob rau hauv 5500 watts, yog li ntawd Nws muaj kev ruaj ntseg dua, thiab nws yog ib qho tsim nyog los xyuas kom meej tias cov pob qij txha sib txuas yog ruaj khov thiab txhim khu kev qha, thiaj li ua kom muaj kev nyab xeeb.
Under normal circumstances, the difference between the current generated by twisting two wires together is actually relatively insignificant. Generally, the small surface (10㎡) is not recommended and will not be used. Among the wires we use, there are generally only single wires within 6mm2. For some wires with relatively large mm2, multiple wires are actually combined together, and there are no single wires for more than ten square meters. The most used place is in power distribution. Sometimes, due to the difficulty of construction of large-sized cables, two cables are used to solve the problem. As long as the material and length are the same, the current carrying capacity of two conductors with the same surface can reach the same level of one conductor.
Ob lub 2.5mm2 xov hlau yog twisted ua ke, uas yog sib npaug rau txuas ob 2.5mm2 nyob ntawm tej hauv series. Txawm hais tias tus ntoo khaub lig- ntu ntu ntawm ob lub xov hlau sib tw ua ke yog 5 hli 2, lub peev xwm nqa tam sim no tsis yog tam sim no ntawm 5 square xov hlau. , Hauv qhov no, nws tsuas tuaj yeem hais tau tias ob lub 2.5mm2 cov xov hlau muaj cov khoom sib txawv raws li qhov sib txawv, thiab thaum peb siv lawv rau lub sijhawm ntev, cov xov hlau tuaj yeem ua rau kub thiab kev laus, thiab qhov xwm txheej hnyav, hluav taws yuav tshwm sim.
Txij li thaum qhov kev tiv thaiv ntawm cov hlau tsis sib txawv thaum peb ntswj cov hlau, qhov tam sim no kuj tsis sib xws thaum siv, uas yuav ua rau cov xaim nrog lub zog loj dua, thiab tseem yuav ua rau kev laus ntawm cov hlau, uas yuav siv sij hawm ntev. Yooj yim ntes hluav taws. Yog li ntawd, thaum peb siv cov xov hlau, peb tsis txhob sib tw ob lub xov hlau ua ke, thiab peb tseem yuav tsum tau teeb tsa qhov xav tau tiag tiag ntawm lub voj voog los xaiv cov xov hlau. Kev nyab xeeb hluav taws xob tseem tseem ceeb dua.
Cov phooj ywg uas paub txog tam sim no yuav tsum paub txhua tus paub tias tam sim no dhau los ntawm txoj kab nrog kev tiv thaiv me me, uas yog hais tias, uas tooj liab xaim hauv ib lub xaim muaj qhov qis tshaj plaws, uas tooj liab xaim tam sim no dhau los ua ntej, thiab qhov seem tam sim no dhau mus. los ntawm cov hlau hauv ib ntus. Yog tias peb twist ob lub xov hlau ua ke, peb tsis tuaj yeem ua tiav qhov sib txawv winding ntawm cov xov hlau ua tiav los ntawm lub Hoobkas xaim. Yuav muaj tiag tiag qee qhov chaw uas tau xoob thiab qee qhov chaw yog nruj nruj, ua rau tsis sib haum xeeb ntawm cov xov hlau, thiab tam sim no yuav tsis ntws. Uniformity, tshwj xeeb tshaj yog nyob rau hauv cov pob qij txha. Vim qhov tsis sib xws tam sim no, cov hlau yuav sov, thiab kev laus yuav nrawm dua tom qab lub sijhawm ntev, thiab cov hlau yuav ntes hluav taws, uas yog qhov txaus ntshai heev. Yog li ntawd, nws tau pom zoo ntawm no tias koj yuav tsum tsis txhob ntswj ob lub xov hlau ua ke, thiab tsim ua raws li tus qauv kev coj ua ntawm cov kab sib txuas, txwv tsis pub nws tsis zoo heev.
Qhov zoo ntawm cov hlau ncaj qha cuam tshuam rau kev ua haujlwm kev nyab xeeb ntawm txoj kab. Thaum txoj kab tsis tuaj yeem ua haujlwm ruaj ntseg thiab ruaj khov, lub neej thiab kev lag luam poob los ntawm nws qhov tsis ua tiav yog qhov tsis tuaj yeem xav txog. Yog li ntawd, peb cov neeg ua haujlwm hluav taws xob hluav taws xob yuav tsum ua tib zoo tiv thaiv qhov tshwm sim ntawm cable tsis ua haujlwm ntau li ntau tau. Txo cov kab mob sib kis, pib los ntawm kev hloov maj mam, thiab siv zog ua kom tiav lub hom phiaj ntawm kev nyab xeeb thiab ruaj khov fais fab mov.
