Inhlanganiso zamanje

isimo ekuphileni Okuvamile - kubalulekile ukufaka inkinobho entsha noma esidayisa kuleli zwe. Konke lokhu - isokhethi, ngocingo, iziqobosho, wakhetha indawo ukufakwa. Thatha sokuwenza bese uyawenza. Kodwa cha! Ngikhohlwe ukuhlola, futhi ngisebenzisa wire kungaba etholakalayo? Ukuze kutholakale isidingo kungenzeka ukusebenzisa elithi ezifana kwabantu kwamanje, futhi uthole inani layo ovumelekile.

Kuyini lokhu sibalo, futhi kungani bubaluleke kangaka? Kukholakala ukuthi ngaphansi kwezimo ezivamile of kagesi sidlula lonke ivolumu umqhubi. Kalula - ukubaluleka wamanje egeleza ngokusebenzisa kwesigaba umqhubi kubhekwa ukuminyana yayo. Ukuze nesilinganiso yayo uhlelo SI isebenzisa iyunithi efana kuyinto ampere per imitha square (A / m), futhi kwamukelekile ukusungula lapho egeleza ngokusebenzisa zamanje wire.

izidingo kuphi ezinjalo? Kulula kabi. Umqhubi ngamunye has a ukumelana ukugeleza zamanje, lapho "elahlekile" ingxenye. Lokhu "elahlekile" izimbangela zamanje Ukushisa umqhubi. Uma ukulahlekelwa makhulu, bese kulandele ngokweqile ukushisa umqhubi, futhi lincibilike. Ukuze lokhu kasekho, ngoba uhlobo instrument ngalinye lihlelwe ukuminyana kuvunyelwe zamanje, ukuhambisana okuzokwenza ukuqinisekisa ukusebenza onokwethenjelwa wiring.

Manje kumele kube sobala ukuthi uma kukhethwe kahle ingxenye umqhubi, isb kuthiwa usebenzise umthwalo, okuyinto ngezikweletu amandla abalulekile, noma kokubili zihlanganisa zikagesi eziningana yasendlini (iketela, ikhompyutha, i-TV, njll), ukugeleza zamanje kuzokwenza Ukushisa enkulu izintambo, futhi ancibilike. Noma ukukhonza njengephayona imbangela yomlilo.

Yingakho kukhethwa umqhubi cross-izigaba, noma kunoma yiliphi elinye icala, lapho uxhumano umthwalo okuhleliwe, kubalulekile ukuba acabangele ukuminyana kuvunyelwe zamanje. Lapho efeza umsebenzi design leyo njongo amafomula akhethekile amatafula esetshenziswa onjiniyela. Nokho, ukubala ingxenye wire phezu ovumelekile kwabantu kwamanje inika yamukeleka kusukela iphuzu eliwusizo umbono umphumela.

Kuze kube yimanje, asikho isidingo ukusebenzisa amafomula ayinkimbinkimbi nama-spreadsheet nzima. Kuyinto kudingekile kuphela acabangele kwenani elifanayo - kwabantu samanje wire yethusi akufanele idlule amperes sq ngayinye eziyisithupha kuya kweziyishumi. milimitha. Idatha ngenhla isebenza kuzo ithusi. Njengoba manje isetshenziswa ngokuyinhloko izintambo zethusi, lezi idatha kumele kwanele ukuba isifundazwe ukunquma ukusebenza yayo.

Lezi zibalo kumelwe siwaqonde ngokuthi elandelayo. Ngo ukusebenza okuqhubekayo kwabantu samanje wesifunda kumele singeqi 6 A / sq. mm. Khona-ke, wiring izoqalisa kumodi e-lite, futhi ingasetshenziswa isikhathi eside. Nokho, kungase kube eziqhutshwa Mode 10 A / sq. mm, kodwa umbuso ezinjalo kufanele nayo ibingaba eyesikhashana.

Njengokulotshiweyo ukuthi bakwenze? Kuyadingeka ukucacisa esiphezulu exhunywe umthwalo. Makube njalo, isibonelo, ngesikhathi esifanayo ukuthi ifake i Iqhwa ngezibani ezinhlanu Watts 100, i-TV, i-computer, esiqandisini. Umthamo inani ezingekho ngaphezu 5 kW yahlukanisa leli sibalo yi amapayipi voltage, 5,000 Watts ehlukaniswa 220, sithola round izibalo 23A eyesiSekelo. Kusho ngokusipha operation yesikhashana ezifana zamanje ndima kudingeka zethusi wire 2.5kb. milimitha.

Ungakwazi sondelana lo daba ngendlela ehlukile. Uma esitolo esidayisa kulotshiwe ukuthi yakhelwe 6A zamanje, bese usebenzisa wire yethusi ezingaphezu kweyodwa sikwele. mm akudingekile, izisekelo bazishisa phambi. Vele ukuze uthole ulwazi oluthe - uma indima okokusebenza conductive kuyinto aluminum, kuvunyelwe ukuminyana lwamanje 4-6 A / sq. mm. Ngakho, esebenzisa lezi zibalo, unqume ukuthi yikuphi ingxenye wire kumele sisetshenziswe Wiring idivayisi.

Indaba oshiwo ngenhla inikeza incazelo umqondo wegama elithi "ukuminyana zamanje". It wachaza isidingo ukusebenzisa kwayo ukuze ukhethe oyifunayo usayizi wire. I izincomo eziningi ezisebenzayo maqondana nokusetshenziswa kwale ipharamitha ngesikhatsi kokuhlinzwa.
