Terminals sezintambo yokuxhuma: isikulufa, ukusatshalaliswa, amandla

On kanjani ukuba okuhlala kanye enokwethenjelwa uxhumano kagesi kuncike ukuphepha futhi ihlala isikhathi eside. contact Good phakathi izintambo futhi ukunika esitebeleni bushelelezi voltage wesifunda futhi ngaphandle kuzuba. Kodwa uma ngezinye izikhathi ungathola ukusonta evamile, ezimweni eziningi, le ndlela akwamukelekile, futhi kubalulekile ukusebenzisa imishini ukuze wiring ukuxhumana. "Kungani?" - You buza. Asivume.

Block esibulalayo kungcono ukusonta?

Electricians abaningi, phakathi lapho kukhona kakhulu ochwepheshe abaqeqeshiwe futhi abanolwazi, bathi kangcono kunamanye ikamu - the twist evamile. Lokhu kuyiqiniso, kodwa ngokwengxenye kuphela. Iqiniso liwukuthi kuxhomeke kakhulu imishini ngawo sibhekene nezinto okwenza wire ixhunywe, nezinye izinto. Lokhu unganakile kungase kubonakale trifle, kodwa empeleni kancane ezahlukene.

Ukuze ukhulume iqiniso elilodwa elishiwo ezithakazelisayo. Imithetho wiring umsebenzi siyavuma ukuthi twist e wonke amalunga akuvunyelwe. Ngenxa yalesi sizathu elula, noma yimuphi inhlekelele lokho kwenzeka ngenxa yokuthi uye wasebenzisa i uxhumano kungavunyelwe kwenzeka uwena obangele ukuba akuthinte. Ngaphezu kwalokho, imithetho Ukufakwa kagesi (PUE) avumele sonke 4 izinhlobo zezakhi, ezinye zazo sizokhuluma ngani kulesi sihloko.

Kuyini block esibulalayo?

Isikhumulo - ithuluzi ekhethekile, okuyinto lingasetshenziswa esigungwini isikulufa noma ukuvimba. Isetshenziselwa uxhumano okuphephile izintambo. Kunezinhlobo eziningi nobukhulu Combs yesimanje. Kodwa kuyafaneleka ukuthi ezikhumulweni yokuxhuma izintambo yokuvikela kalula intambo ngaphandle kokudala ke kulimaze.

Kukhona izindlela eziningana ukulungisa izintambo, ethandwa kakhulu - ukukhweza ngaphansi kwekhanda isikulufa. Futhi esetshenzisiwe Ukwethula ophoqelelwe ngokusebenzisa ipuleti isikulufa uxhumano. Imiphumela iba yinhlanganisela yokukhandleka contact enokwethenjelwa kakhulu futhi akabubangeli umonakalo mechanical kuya ngocingo.

Kwezinye izimo, ezikhumulweni kwentambo uxhumano babe amathiphu ekhethekile. Basuke usufakwa ikhebula, okuyinto ke unamathisele kwikhabhinethi noma yimuphi omunye zikagesi. Combs maKristu abizwa looping.

Intulo block esibulalayo futhi incazelo yalo

On isicelo isikulufa Combs ungakwazi ukukhuluma phakade. Empeleni, kuba ezikhumulweni ethandwa kakhulu, ukwakhiwa okuyinto onokwethenjelwa futhi elula ngesikhathi esifanayo. Lolu hlobo amadivayisi azisetshenziselwa yokuzalanisa wiring, kodwa futhi ezitolo. Asetshenziswa njengendlela isiqeshana terminals ibhethri, ukuxhumana luminaire amaqembu nokuningi.

Njengoba womshini indaba, terminals isikulufa sezintambo yokuxhuma ngokuvamile ayenziwa ngesikhumba polypropylene futhi polycarbonate, kodwa ngezinye izikhathi zenziwa polyamide kanye polyethylene. Kumele baqonde ukuthi lolu hlobo idivayisi asifanele ukusetshenziswa ne-aluminiyamu babashayeli. Lokhu kungenxa fragility elihlukile esidlule, ngakho lapho ukulungisa wena kungalimaza kubo. Kodwa lokhu nje okudingayo ukuze yethusi nezinye izintambo. Ngokuvamile isisekelo isikulufa esibulalayo block senziwa. Kulokhu, njengoba igama elithi it has a isikulufa oluhlaza, kanye enameva esikhethekile esivusa amadlingozi ngempumelelo wire.

uxhumano ezikhumulweni

ezikhumulweni Intulo, okuyinto sixoxe ukuba ngomunye ezintathu izinhlobo yokuxhuma kumadivayisi sezintambo. Ngokwe-EMP, kungcono ukusebenzisa kakhudlwana futhi ezikhumulweni Self-clamping. Basuke esetshenziselwa ukulungisa kanye wiring sigaba ayibi ngaphezu kuka-2.5 mm ngesikhathi samanje 24 A. ikamu okunjalo ukumelana umthwalo oda 5 kW. Uma imishini amandla khudlwana futhi enamandla, uzodinga ukusebenzisa indlela ehlukile.

Ngokuthakazelisayo, kungenzeka uxhumano esibulalayo amabhodi zalolu hlobo ucingo 8, okuyinto has a inombolo lehambelanako Slots. Lesi sinqumo nomthelela lokuthi zivulelwe kakhulu kusheshiswe amahanisi wiring.

Ngo indlela echazwe ngenhla, kukhona eyodwa ethile. Yena Ngokuqondene isikhala wenyuselwa ibhokisi kwalapho (bese kuphela ngokuziqhathanisa twist). contact ukuphepha nokwethembeka ezingeni kulokhu iphezulu kakhulu, uma singeqi umthwalo ovumelekile. Kungenjalo, amabhlogo uxhumano esibulalayo yalolu hlobo ingase ingase ingaphumeleli noma kube yingozi.

Ukuzihlukanisa ezikhumulweni ngoba wiring

Nangokuvikela izibopho yokuxhuma (PPE), ngokubukeka efana cap plastic. Yakhiwa polymer okungezona oluvuthayo, okuyinto akufaki omlilo nokuguqulwa ngenxa lokushisa kuyanda. Ungakwazi ukuxoxa ngeqiniso lokuthi injongo yabo eyinhloko - ivuliwe abantu bavikelekile ezingozini zomlilo. Nokho, PPE kunomphumela omuhle izinga uxhumano ngokunikeza contact ezinhle lokukhanda. Ukuze wenze lokhu, badinga ukuba bakopele ukusonta bebheke kuhlanekezela izintambo kuleli ikhebula. Ngenxa yalokho, isiphethu kubekwe phakathi kwezindlu, ekucindezela bentambo core, kanjalo ngcono ukuthintana. Icubungula walala nokunamathisela ezikhethekile zokugwema namachibi.

Lapho esetshenziselwa ezikhumulweni kagesi zalolu hlobo, kuba nokwenzeka uvikelekile uxhumano izintambo of diameters ezahlukene. Ungakwazi futhi ukusungula ukuxhumana phakathi ikhopha ne-aluminiyamu izintambo. Ngaphezu kwalokho, entwasahlobo kunomthelela unomphela wire fixed, ngakho asikho isidingo sokuthi zihlolwe, njengoba kunjalo nge isikulufa ukuxhumana.

Akunakwenzeka ukuba uqaphele okumbalwa abalulekile PPE ukuthola uxhumano kuyashesha futhi kuthembekile, okuyinto kungenziwa ngisho by Wabasaqalayo.

Kafushane phezu ezikhumulweni amandla

Omunye ongathi block amandla esibulalayo has a isakhiwo eziyinkimbinkimbi nezinzima okukhulu ukwedlula embodiments ngenhla echazwe. Lokhu kungenxa yokuthi idivayisi ngokuxhumanisa enjalo kuvumela cross-ingxenye enkulu futhi kwamandla izintambo (ngokuvamile kuba kwentambo kusukela 35 kuya ku-300 mm sikwele). basuke igibele obandayo ipuleti ekhethekile noma din-kukajantshi, ngakho ngokuvamile edayiswa izinguqulo eziningana. Imininingwane ipuleti ithusi, camera nge ingxubevange ithini. Vikela has a washers oyindilinga ukuthi ngokuphelele enqanda buthaka oxhumana naye. Ngezinye izikhathi terminals amandla ikuvumela ukusetha ezimbalwa Jumpers owengeziwe ezikhumulweni eduze, okuyinto ekahle kakhulu.

Barrier futhi jikelele ezikhumulweni

Isici esiphawulekayo ezikhumulweni Isivimbo ukuthi babe in design yabo encane yensimbi. Kwakamuva ihlukaniswe ekuvikeleni ungqimba. Lena ezinhle ukusatshalaliswa esibulalayo block, ngoba ayifakiwe ngokuphelele ixhumana izintambo angomakhelwane. Ikhwalithi ephezulu kubangela enye into nokuthi udonga ngamunye has a pair of ngezikulufo. Basuke okudingekayo ukuze thembeke ukukhweza oxhumana.

I amabhokisi ukusatshalaliswa efakwe ncamashi isithiyo amabhlogo esibulalayo, njengoba nje kuvamile namanje esikahle kakhulu futhi enokwethenjelwa. Combs Universal kukhona block itheminali tube lensimbi, ngalinye elikwazi ifakwe pair of nezikulufi zokuthola izintambo. Lena Ukugunda kakhulu uma udinga ukwenza wiring amagatsha.

isiphetho

Manje ngoba sewuyazi ukuthi lokho ezikhumulweni yokuxhuma izintambo futhi yiziphi izinhlobo bakuphi. Kuyaqondakala ukuthi zinsizakuphila zikuvumela ukuba wenze uxhumano, hhayi kuphela, eliqinile, kodwa futhi, okubaluleke kakhudlwana, okuthembekile. Okwamanje, ukudayiswa iyinombolo esikhulu terminals. Ezinye Site izintambo nge encane cross-section, elinye - okwesikhathi esikhulu. Kukhona ezikhumulweni isikulufa, screwless noma umshudo. Sonke sinamandla futhi sibuthaka. Ngenxa yalesi sizathu elula, ukukhetha kumele elungisisiwe kungaleyo ndlela kuphela sithemba Chile oqondile.
