Yikuphi wire esetshenziselwa wiring efulethini? Kukhethwa ye wiring

Wiring ezindlini ezindlini ezindala ezimweni eziningi, kakade igugile kumelwe ithathelwe. Ngaphezu kwalokho, inethiwekhi ubudala asekhaya ngokuphelele hhayi eyenzelwe amandla yesimanje zasendlini. Yiqiniso, uma uthenga izintambo ezintsha kufanele sicabangele ezinye zezici ezibalulekile. Mayelana onjani ngocingo esetshenziselwa wiring efulethini ungcono kakhulu, futhi ngani kulesi sihloko.

Okufanele ayicabangele lapho ekhetha

Into yokuqala okudingeka anqume - engxenyeni ikusasa ikhebula. Lokhu ipharamitha kuncike ezintweni ezifana:

• inethiwekhi obuphelele futhi ngalesosizathu ukumelana;
• umthwalo kulindeleke kuso;
• yokukhiqiza impahla.

Lapho unquma ukuthi imaphi wire isetshenziselwa wiring efulethini inethiwekhi lemifisha osindayo, kubalulekile ukugxila izimo bafudumale. izigaba Cross kolayini eside ngezinga elikhulu incike ukubaluleka ukumelana. Futhi kulokhu, amandla mechanical kubalulekile.

Ngokuphathelene umkhiqizo impahla, okwamanje izintambo ezimbili ezisetshenziswa izinhlobo: ikhopha ne-aluminiyamu. Esimweni sokuqala esigabeni cross lincane lesibili - okukhulu. Ngenxa yalesi sizathu, iningi abanikazi efulethini okwamanje uncamela welule ku izintambo emafulethini zethusi, ube conductivity kangcono.

ukusetshenziswa umthwalo

I Ingxenye evundlile izintambo zikagesi efulethini kumele ibe ngendlela yekutsi abanikazi kamuva kwadingeka ithuba ukuxhuma amandla amadivayisi kunesidingo. Inani lamanje ngoba lisebenze ethile ebizwa ngokuthi I = P / V, lapho P - amandla alo (ingatholakala ishidi idatha), V - the amapayipi voltage. Ngo Zikagesi ngokuvamile 220 V Ngakho, ngokwesibonelo, i-heater kokuba amandla 2000 W, value lwamanje 9 A.

Lesi sakamuva ibalwa zamanje ingqikithi wonke amakhasimende abazoba. I cross-ingxenye zethusi wire kuyakhethwa ikhumbula kuvunyelwe 10 A ngayinye milimitha sikwele. Aluminium - 8 A. Kuleso simo, uma wiring ifihlekile, lezi zimiso kufuneka iphindaphindwe ukulungiswa isici - 0.8. Vula wiring efulethini cishe akazange asebenzise. Nokho, uma ngenxa yesizathu esithile kufanele ukhethe inketho ezinjalo, kubalulekile ukusebenzisa wire sigaba hhayi ngaphansi kuka 4 mm ² kokuba amandla anele lokukhanda. Nge enkulu ukunemba ampacity ku yethusi aluminium eyebiwe zingatholakala kumathebula ekhethekile.

Izintambo ngoba wiring efulethini kungcono ukukhetha abathile amandla Reserve. Lokhu kuzovumela esikhathini esizayo ukuze ukuxhuma kunethiwekhi, usule izinto zikagesi eziphezu entsha, ukuthengwa okuyinto okwamanje kuhlelwe.

Ezindlini ezivamile idolobha kukhanyisa wire yethusi ikhethwa avame cross-section 1.5 ^mm2 ngoba enethiwekhi - 2.5 mm ^2. Ekhishini intambo 4 mm ^2, njengoba kungekho ngokuvamile kakhulu enamandla zikagesi elula kangcono - .. sezitofu, isiqandisi, Umshini wokuwasha izitsha njll Ukukhweza ikhebula Okokufaka efulethini kuyakhethwa ukuze kwesigaba walo wawenziwe isinyathelo esisodwa ephakeme kunaleyo ezidingekile ezinamandla kakhulu ithuluzi ukuze isetshenziswe.

ukumelana

Umbuzo ka onjani ngocingo esetshenziselwa wiring efulethini, kuhlanganise amanani kanye Ukukhetha efanele esigabeni cross ngokuya kungenzeka voltage ukulahlekelwa. Lines ngisho ezindlini zasemadolobheni made ngempela. Kulokhu, voltage ukulahleka izintambo ongafinyelela inani kungamukeleki. Ukukhetha ukwenza kanjalo ukuthi lesi silinganiso ingeqi 5%. Kufanele uqale ukubala isikhathi ukubala amathonsi umthwalo voltage. Ngenxa yalesi amandla kW iphindwe ubude ikhebula ngamamitha. Ngaphezu kwalokho amatafula ekhethekile sokunquma ukulahlekelwa iphesenti langempela. It kuzoncika torque umthwalo, intambo cross-section futhi ubude bayo. Kukhona amatafula ehlukile ezintathu okhombisa nasezakhini isigaba amanethiwekhi. Nokho, qaphela ukuthi basuke iphesenti ukulahlekelwa ngaphandle Ukushisa ikhebula lapho sidlula-ke lamanje ecacisiwe. Ngalokho khethani kwesigaba wire kulokhu kufanele futhi ngemajini. Okungukuthi, sibheke ukubaluleka etafuleni elihambisana kungekho 5, no-4%.

wire ezithambile

Ukuze izakhiwo ngokuvamile akhethe izintambo ezithambile nezimo. Ngamunye core kulokhu siqukethe inqwaba babashayeli mncane. Lezi izintambo kulula donsa on zokuhlala isakhiwo eziyinkimbinkimbi kunothile esonta. I ethile kuphela izintambo esithambile ukuthi banayo ukuba crimp ocindezelwe ungene kubo ithiphu ekhethekile lapho wiring ixhunyiwe.

ezinzima

Kukhona olunye uhlobo ikhebula - kanzima. Kulokhu, umongo ngamunye siqukethe umqhubi olulodwa. Empeleni, kungakhathaliseki ukuthi hlobo luni wire for wiring efulethini izokhetheka - nezimo ziqinile. Into eyinhloko ukufanisa ikhebula imithwalo ke kubathengi. Edolobheni efulethini ngokuvamile akhethe izinguqulo ezintathu-core wire isisekelo. Izinto zokuvala umoya kuleli cala kuyodingeka lowehlukile. zihambisana Brown noma obomvu siyinikeze umqhubi isigaba, blue - zero, ophuzi - emhlabeni.

Elivame ukusetshenziswa kakhulu ibanga wire

Omunye okukhethwa athandwa kakhulu iyona ikhebula NYM ngoba wiring efulethini efanelekayo kahle. Umelela okuhlukile owodwa nalevulekile nezimo buphele futhi has simise isiyingi. Enye inzuzo ukuthi khona lwezimpawu ezimbili. Izimo yokugcina kwenza kube engangenwa umlilo.

Olunye uhlobo, ngokuvamile sisetshenziswa zokuhlala, - olulodwa-wire ikhebula VVG, okungaba round noma flat. Lokhu samuntu leaner kuka NYM, futhi ngokufanelekile, kuyinto elula ngaphezulu emakhiyubhi. zako, phakathi kwezinye izinto, singasho sithi hhayi eqolo.

Esesithathu inketho ethandwa - balahleke PVA. Lokhu ikhebula round has a nezimo ngokuphelele ezinhle kakhulu. Ngokuvamile isetshenziselwa ekhaya Imishini endaweni ikhebula inethiwekhi. Nokho, ngenxa yokufaka lemigqa kuyavumelana kahle.

Yini enye okudingeka ukwazi

Kuleso simo, uma wiring engabe ukudonsa okwakhiwa ngalo la mabhodi yokuqedela noma boarding ophahleni, sebenzisa intambo engasekeli amandla omlilo. ongakhetha ezinjalo ziphawulwe izinhlamvu "NG". Okuhle nakakhulu zisebenzisa ikhebula okungezona oluvuthayo kanye «ls» Inkomba. Ukwahlukanisa we izintambo esimweni umlilo ngeke zabela intuthu eziyingozi kanye amagesi.

Okuhle kunakho konke ukuthi, uma wiring ikhebula efulethini uzobe kabili ngci. Kunoma ikuphi, londoloza kule akudingekile. Kungenjalo, isibonelo, uma izikhukhula efulethini ingaphinda nomlilo ukuzehlukanisa olulodwa kaningi nje lilimele ngesikhathi sokufaka noma ngesikhathi operation.

Indlela ukukhetha ukushintsha

Ngakho, usuthathe isinqumo ku ngumuntu wire esetshenziselwa wiring efulethini. Nokho, izintambo - kuba Yiqiniso, akuyona kuphela elementi inethiwekhi. Ngaphandle kwabo, uzodinga ukuthenga izesekeli more and more. Ishintsha akhethiwe ngokuyinhloko ngesisekelo onjani cabling asetshenziswe efulethini - livuliwe noma livaliwe. Yiqiniso, inketho wokuqala kuleli cala kuyaqabukela asetshenziswa. Ngakho-ke, i-efulethini ezisemadolobheni, cishe, uzodinga ukuthenga ukushintsha ezishaywayo.

Ngaphezu kwalokho, lezi zinto inethiwekhi ayatholakala nge isikulufa futhi screwless ezikhumulweni. Inketho yokuqala kungenzeka ungumuntu omuhle uma izintambo zikagesi efulethini welulela usebenzisa aluminium eyebiwe. I last angagcina podplavlyatsya kancane futhi aqale ukucwazimula. Kulokhu, kuzoba ngokwanele nje qinisa ngezikulufo. Ukuze zethusi wiring ngokuvamile ezikhethiwe ukushintsha isango ezikhumulweni. Benza izinto zibe lula kakhulu uma yokuxhuma.

Ukukhethwa Izitolo

Le nto engcono ukukhetha, uholwe abakhiqizi. Nokho, isidingo ukuba siqaphe mbumbulu. Kulo mBhalo of ezitsheni zifike, isibonelo, nephunga edabukisayo. Ngaphezu kwalokho, umkhiqizo yekhwalithi ephansi ngokuvamile eyenziwe ngepulasitiki mncane kakhulu noma soft. Esidayisa kumele kube ngokwanele ezinzima. Futhi banake isimo loxhumana naye phansi. Kufanele bend.

Kufanele kuthathe nawe esitolo bese uzama uxhume ukuze sivale kube izisekelo. Yiqiniso, akufanele hang nokuwa. Ngenxa yalesi samuntu, njengenhlangano wiring zangaphandle ifulethi, njengoba kwaba njalo endabeni ka-ukushintshwa, nezinyawo asetshenziswa design akhethekile.

Namuhla, emakethe ingabhekana kanye ekhethekile izinhlobo nezinyawo, ayihlomele, isibonelo, nezixhumi USB noma LED-ekhanyayo. Ungase kukhethwe uma uthanda futhi i samuntu ezinjalo.

Nokho, sithemba athikili yethu kuyokusiza ukucacisa umyalelo ngocingo esetshenziselwa wiring efulethini idolobha. Izinketho okwamanje, kunezindlela eziningi. Into ebaluleke kakhulu - ukusebenzisa izintambo efanelekayo amadivaysi amandla sokulondeka seqophelo eliphezulu.
