Zokushisela zethusi wire: sokubuyekezwa izindlela zokusebenza nemishini. Nokunamathisela ngomthofu noma Welding izintambo zethusi - okuyinto engcono?

Umsebenzi oyinhloko uma uxhuma singalokothi sithintane kagesi wukuqinisekisa ukumelana yabo ubuncane. Lapho ukumelana contact abampofu phakathi izintambo lethusi ngcono kakhulu, okubangela Ukushisa ikhebula. Ziningi izindlela ukuxhumana ukuxhumana, kodwa enokwethenjelwa kakhulu futhi ngempumelelo kubhekwa ashiselwe wire ithusi. Lokhu ubuchwepheshe ivumela monolithically ukuxhuma zonke imicu wire, kanjalo ekufezeni ephansi okunokwenzeka ukumelana kagesi. Ngenxa yalokho Ukushisa izintambo siqedwa, ngaleyo ndlela kakhulu anda izinga lokuphepha umlilo.

Izindlela uxhumano izintambo

Ithusi main umqhubi impahla. Ngenxa sezindawo physico-amakhemikhali le nto (ductility okusezingeni eliphezulu, ukungabi kuyaqina), usebenze nabo has izici zayo siqu. Kagesi imithetho apharathasi bathi kungenzeka imisebenzi igatsha uxhumano kanye emithanjeni okontsovyvaniyu samakhebula futhi izintambo eyenziwa nokunamathisela ngomthofu, Welding, crimping noma ecindezela (umshudo, isikulufa, njll). Ngamunye wabo has izici zayo siqu, okuzoxoxwa ngezansi.

izintambo Compound ngu stranding

A twist okulula izintambo asivunyelwe PUE, njengoba kuba kahle kakhulu, uxhumano esifushane futhi umlilo. Naphezu kwakho konke lokhu, izingcweti yasekhaya futhi bengayeki ukusebenzisa le ndlela, yize imiphumela yalokhu "izikebhe" kungaba plavchevnymi kakhulu.

Ukusonta izintambo has eyodwa enkulu ethile: uxhumano zethusi ekugcineni zikhubazekile futhi buthaka, yagcina ibhujisiwe ngokuphelele ngenxa okusezingeni eliphezulu inguquko ukumelana.

Kufanele kukhunjulwe ukuthi indlela ukusonta singasetshenziswa kuphela ezimweni ezingavamile, uma kunesidingo esiphuthumayo okusemandleni ukubuyisela ugesi kanye nezinye izindlela esimweni esithile azitholakali. Kubalulekile kakhulu ukuba uqaphele mayelana nekhwalithi, ukuphepha kanye ukuthembeka uxhumano.

It is nhlobo:

• Ixhuma izintambo ezakhiwe ngezinto ezahlukene (aluminium nethusi);
• Ukuxhumanisa okuqinile zethusi wire nge multifilamentary.

inqubo Stranding simiswe ngalendlela lelandzelako:

1. Sula wire ukwahlukanisa kusuka ibanga 6-8 cm kusukwa;
2. Sebenzisa wire omunye komunye bese crosswise eluka Ubuningi bamahora obukhulu. Uma Ingxenye evundlile wire yethusi ezingaphezu kuka 1 sq. mm, ukuhlinzwa owazenza impintshisi.
3. Bite amathiphu esebenzisa asele izintambo.
4. Iphutha ngci usebenzisa ekhethekile ekuvikeleni izinto (PVC, noma ukushisa Nciphisa amashubhu, amakepisi) noma izingqimba eziningana nangokuvikela tape. Izinto zokuvala umoya kumele ngempela uthwebule ekuvikeleni ungqimba izintambo.

ingcindezi test

Inqubo inqubo yokuxhuma izintambo ngokusebenzisa ekhethekile yabo crimping a se ijabulise noma ithiphu. asetshenziswa Lezi amadivayisi, uma Ingxenye evundlile wire nethusi 2,5-240 sq. mm. Izinzuzo obungenakuphikwa ka crimp yobuchwepheshe speed nokunemba lomsebenzi, kanye okwalandela ukuqina nokuphepha ukuxhumana.

Ukuze crimping usebenzisa ithuluzi ekhethekile - mechanical, impintshisi wokubacindezela kagesi noma noma professional obzhimochnye cindezela. Ukukhethwa casings liyakushunyayelwa esekelwe izingxenye eziningana futhi zixhunywe izintambo.

Ngemva bula futhi yokuhlanza eziphilayo, zingabantu osetshenziswayo asebenza ngebhethri-Vaseline unamathisele, ukugqoka emikhonweni futhi ukukhiqiza crimp. Kokucindezela imikhono ekhishwe inyumbazane.

Crimping ezikhumulweni

Isicelo ezahlukene crimps ezikhumulweni futhi kugcwele ngokuxhuma Izitolo zikagesi, ukushintshwa, zalapho ukukhanya, kanye ukufakwa Switchboards. Lezi amadivayisi uvumele olunembile futhi sisheshe zethusi ukuxhumana ngocingo eziqinile, wire balahleke kodwa ngaphandle pre-welds noma crimp tube ithiphu ku esibulalayo isikulufa ngocingo akunakwenzeka.

Izinzuzo obungenakuphikwa terminals isikulufa ingase ihlanganise lwenethiwekhi aluminium wiring ngethusi, futhi asikho isidingo ukuba abe yedwa okwalandela othintana.

Nokho, lolu hlobo lwe-inthanethi lungeluhle ngaphandle amaphutha. Kudingeka yesondlo gqwa, esakhiwa ngo ezimazombe izakhi clamping. Copper - material soft kakhulu, uthambekela "ukuvuza" kusukela ngaphansi umthwalo. Uma ngisho ukwenza ukuxhumana esebenzisa entwasahlobo-ukulayishwa isandla ezikhumulweni cleat, ngenxa incane kakhulu evele endaweni contact komthwalo osindayo uyabaselwa nokukhululwa izakhi entwasahlobo, lapho kuyaqina yabo incipha kanye izinga kwakwakhe.

Pike VS-Welding

Ukuqinisekisa contact ezinhle ngokuvamile isetshenziselwa nokunamathisela ngomthofu noma Welding izintambo zethusi. Lokho okungcono yalezi zindlela? Nakanjani, Welding. Iqiniso lokuthi nokunamathisela ngomthofu - nqubo ngempela kukhathaza futhi eside, ikakhulukazi uma ufuna ukuxhuma Stranded zethusi ikhebula. Plus, zezakhi commissural yagcina ibhujisiwe ngenxa yokuba khona we metal lwesithathu, friable futhi kalula fusible - solder. Ukuba khona ukumelana shintsho emalungeni Alloys ezahlukeneyo kunomthelela ukubukeka elimazayo chemical ukusabela nezinye izinqubo ezimbi.

Lapho Welding wenziwa zethusi wire, igama elithi "contact" ngokuvamile ziyanyamalala ngoba kwakwakhe Monolithic is etholakala uhlobo olufanayo metal. Njengoba kulindelekile, laba compounds kuhluke irekhodi ukumelana ongaphakeme, lapho ukushisa neze ikhishwe.

nokunamathisela ngomthofu

Ngokushesha kufanele kuphawulwe ukuthi lo msebenzi kudinga ethile yolwazi nokuhlangenwe nakho. Kuyindida kodwa izinga kangcono ezimazombe nokunamathisela ngomthofu abampofu, khumbula lokhu.

inqubo nokunamathisela ngomthofu iqala nge pre-ekwelapheni emikhawulweni izintambo ukwahlukanisa kanye oxides. Babe iphuma, kwagcwala isakhi esithile esikhethekile - ecucuza ke Hocus. Solder izintambo zethusi can hhayi kuphela, kodwa futhi aluminium, into esemqoka - ukukhetha yokucucuza kwesokudla futhi solder. Ukusebenzisa asebenzayo acid ecucuza is hhayi Kunconywa, njengoba kudingwa ukuhlala phezu izintambo, yokuthi kwakwakhe siyochithwa ngokushesha.

Omunye nokunamathisela ngomthofu kuthatha isikhathi eside, kodwa uma kwenziwe ngendlela efanele, i-inthanethi ngeke okunokwethenjelwa futhi iqine. Uma izintambo selehlile, kumele ngci ngokucophelela.

Welding

I eliphezulu kakhulu futhi ukuxhumana okuphephile yakha wire Welding zethusi. Ukumelana in wire contact ingeqi isilinganiso esezingeni ukumelana yabo. Le ndlela akudingi isikhathi esiningi ubhekwa elula. Ephambi kwezinduna zingancane wemakhono nolwazi zokushisela izintambo zethusi ekhaya doable.

Lapho enza umsebenzi Welding yonke imithetho umlilo nokuphepha kagesi kufanele kuqashelwe ngokuqinile. Ukuze ugweme ukusha futhi ukulimala iso kufanele ngaso sonke isikhathi usebenzise siqu imishini zokuzivikela - izingubo ezivikelayo amagilavu, Welding nangesigqoko noma amagogolo.

imishini zokushisela

Compound izintambo ngo Welding wenziwa apparatuses zezinhlobo ezahlukene. Kuyinto elula kakhulu ukusebenzisa i-apharathasi inverter ukuze Welding izintambo zethusi, kusukela kulolu hlobo amadivayisi zinezikhathi usayizi amancane nesisindo, ukonga amandla ukusetshenziswa anhlobonhlobo Welding izilungiselelo zamanje. Lezi izinzuzo kukhona ikhono ukunikeza esivuthayo okuqhubekayo arc kagesi.

Uma kuhlelwe imali ethe umsebenzi kagesi, yokufuna inverter umshini Welding kuyafaneleka ngokuphelele futhi kuyafaneleka. Ngaphezu kwalokho, lo mshini ngokuqinisekile ngeke aqambe amanga 'isisindo efile "esikhathini esizayo.

Izici inqubo Welding izintambo kusukela zethusi

Welding zethusi wire kungaba kokubili AC futhi DC voltage ngamanani of 15-30 C. Kuyinto enhle uma idivayisi inikeza ithuba ulungise zamanje.

Ngokwesibonelo, ukushisela babashayeli ezimbili zethusi 1.5 sq. mm, ngokwanele 70 A. Ukuze Welding izintambo ezintathu nge efanayo esigabeni cross kuyadingeka ukwandisa wamanje kuya ku-90 A. Compound babashayeli ezintathu 2.5kb. mm kuzodinga kusuka 80 kuya ku-100 A, a wire Welding ezinhlanu ezifanayo - 120 I. Uma kukhethwe Welding elikhulu zamanje ingekho 'osekela ngcono "we electrode kanye arc uzinzile ngokwanele.
Ukuze Welding izintambo zethusi ezazisetshenziswa carbon-copper "amapensela" (electrode). Uma kungenjalo, kungenzeka ukusebenzisa carbon izintonga amabhetri ipensela.

imikhuba Welding

Amathiphu ubude wiring ka 5-6 cm sasicwengwa i enamathela ekuvikeleni futhi ezisontekile kusukela izigaba ukwahlukanisa, kusale 5-6 mm ekupheleni twist ifomu untwisted. Lezi amathiphu kumele ukusakaza, eligoqiwe kuqondane and eduze komunye nomunye. Ngu ezimazombe izintambo ezintathu noma ngaphezulu, ekupheleni usadinga ukushiya tip khulula ezimbili kuphela, kanti bonke abanye anqunywe ngilungele round lokugcina abavamile. Uma umshini akuyona wawunamandla ngokwanele, le twist kuzovumela kalula akha bead ncibilika. Uma kukhona zamanje elanele apharathasi Welding ongenza twist elula.

Ngaphezu kwalokho ukusonta aboshezelwa nge clamping Welding. Uma ngabe le divayisi engekho, ungasebenzisa impintshisi plain ubudala.

Egcekeni uzilungiselele ukuthi ashiselwe carbon electrode. Phakathi Welding, izintambo zethusi kukhona elicibilikile kwesokunxele emaphethelweni untwisted ngaphambi obumba ibhola esibunjiweyo. Ukuqinisekisa oluthembekayo mechanical kagesi kanye contact ngocingo, ezonini ukuncibilika kufanele aqiniseke ukuya stranding.

Ubude besikhathi Welding kumele singeqi imizuzwana 2-3, kungenjalo ngocingo ukwahlukanisa weld. Ngemva Ukupholisa ephelele enkompolo ekhiqizwa kude kwaso usebenzisa ezelekene tape noma cap ekhethekile, PVC, noma ukushisa Nciphisa tubing.
