the one-way length of the cable, the area field is the value of the resistivity of the metal (copper ≈ 0.0175 Ω·mm²/m, aluminium ≈ 0.0282 Ω·mm²/m), and the area field is the value of the resistivity of the metal (copper ≈ 0.0175 Ω·mm²/m, aluminium ≈ 0.0282 Ω·mm²/m). The area field is the value of the resistivity of the metal (copper).As
Imibuzo ebuza rhoqo
Ukhupho lwevoltage lubalolwa njani?
Kwimeko enye, iVdrop = 2 × ρ × L × I / A. Umzekelo 2 uchaza umsinga ohamba ngaphandle nobuyela umva; imeko ezintathu isebenzisa i√3 endaweni ye-2.
Yintoni i-voltage drop evunyelweyo?
Umthetho oqhelekileyo wokuba ugcine ukuwa okupheleleyo ngaphantsi kwe-3% kwizakhiwo zesiqhamo kunye ne-5% ngokubanzi. Abaqhubi abakhulu (indawo enkulu) banyusa ukuwa.
Intsimbi engenasici okanye i-aluminium— ngaba kubaluleke?
Ewe. I-aluminium ine-60% engaphezulu yokumelana nokumelana nentsimbi, ngoko i-aluminium ehambayo elinganayo ubungakanani ikhupha uxinzelelo oluninzi.
Kutheni ifomula isebenzisa ubude kabini?
Umsinga kufuneka uhambe ngaphandle kumthwalo nobuyela umva, ngoko umjikelezo wexesha elinye ubona ukuwa kwazo zombini izikhombisi-zintambo - ngoko ke isizathu se-2 × ubude. Umjikelezo wexesha elinye usebenzisa i-√3 ( malunga ne-1.732) endaweni yoko, ubonisa ubukhulu bezinto ezijikelezayo zemandla elilinganayo lexesha elinye.
Ndiyikhupha njani intlungu eninzi yevoltage?
Sebenzisa umqhubi omkhulu (ukuphindaphindwa kokunqunyulwa okujikelezayo okunokwenzeka ukuba kuphelelwe lixesha), khawulezisa uqhubo, uhlukanise umthwalo phakathi kweentambo ezihambelanayo, okanye ukhuphe unikezelo lwevoltage. Intsimbi enkulu ilula kuba ukhupho luyinxalenye ejikelezayo yendawo.
Ingaba kulahlekile amandla amaninzi kwintambo yentsimbi?
Umandla olahlwayo ngumhlathi wexesha lomsinga, Ploss = Vdrop × I. U3.5 V umngcipheko kwi-20 A ulahlwayo 70 W njengefuthe kumsonto-umandla ohlawulayo kodwa awusebenzisi, oko kukuthi, inkqubo ende yomsinga ophezulu iqinisekisa ubunzima, intambo ephantsi yolahleko.
Ndingasebenzisa i-AWG i-gauge endaweni ye-mm² yendawo?
Ewe. Khetha umlinganiselo kuluhlu oluphambili lwe-AWG kwaye lugqithise indawo yendawo enendawo yomhlaba kunye nomfanekiso ojikelezayo we-AWG kwi-mm² (umzekelo 10 AWG ≈ 5.26 mm²), ukuze usebenze kwinkqubo yovavanyo olusetyenziswa ngabafakeli baseMntla Melika.
API — sebenzisa le calculator ukusuka kwikhowudi
Nceda le kalkulator njengendawo esemva ye-JSON ekhululekileyo - akukho qhosha lifunekayo. Thumela amaxabiso endawo engezantsi njengeparameter yombuzo okanye i-JSON. Nantoni na oyenzayo isebenzisa okungagqibekanga okufanayo eli phepha ligqityiwe ngaphambili; iparameter engaziwayo yi 400, ayikho i zero ekhululekileyo. Funda i-API epheleleyo →
