I-Voltage Drop Calculator
Linganisa i-voltage elahlekile esigabeni socingo oluhambayo kusuka kude, namuhla kanye nobukhulu bomuntu ohambayo.
Iziphetho zivuselelwa uma ubhala.

Imibuzo ebuzwa kaningi
Uhlu lwezibalo
Uhlelo olulodwa, Vdrop = 2 × ρ × L × I / A. Umphumela 2 uchaza ukushayela kwamanje ngaphandle nokubuyela emuva; uhlelo oluthathu lusebenzisa √3 endaweni ye-2.
Yini ukuwa kwe-voltage okuvunyelwe?
Umthetho ojwayelekile we-thumb ugcina ukuboshwa okuphelele ngezansi kuka-3% kuma-circuits engxenyeni kanye no-5% ngokugcwele. Abaqhubi abakhulu (indawo enkulu) bakhuphula ukuboshwa.
I-copper noma i-aluminium — ingabe kubaluleke?
Yebo. I-aluminium ine-60% ephakeme kakhulu yokumelana ne-copper, ngakho-ke i-aluminium ehambayo elinganayo ikhuphuka ngokulinganayo.
Kungani ifomu lisebenzisa ubude obuphindwe kabili?
Ngokuba ikhona ukudlula ngaphandle ku-ubunzima futhi emuva, ngakho umjikelezo isigaba esisodwa ibona ukuwa kwezingu-2 conductors - ngakho isizathu 2 × ubude. Three-phase umjikelezo sebenzisa √3 (ngo-1.732) endaweni, ebonisa i-geometry of balanced three-phase power.
Ngingayinciphisa kanjani i-voltage ephansi kakhulu?
Sebenzisa umqondisi omkhulu (ukuphindeka kwengxenye engqubuzanayo kwenza kube ngaphezu kwengxenye yokufa), cindezela ukushayela, hlukanisa ubunzima phakathi kwamakhebula afana, noma ukhuphule ukukhiqizwa kwe-voltage. I-copper enkulu iyinto ejwayelekile ngoba ukufa kuhlobene ngokuqondile nendawo.
Ingabe amandla alahlekelwa yinani elikhulu esigabeni?
Umandla olahlekile yisikhathi sokwehla isikhathi samanje, Ploss = Vdrop × I. A 3.5 V ukuwa ku-20 A ukungcola 70 W njengengcindezi ku-wire - amandla okhokha kodwa awusebenzisi, ngakho-ke uhambo olude oluphezulu lwamanje luqinisekisa ubukhulu, ikhebula eliphansi-lokulimala.
Ingabe ngisebenzisa ama-AWG gauges endaweni yendawo ye-mm²?
Yebo. Khetha i-gauge ku-AWG osheshayo futhi i-AWG i-gauge i-ga
