Three-pole wesifunda full: i Uhlolojikelele, izinhlobo, izici kanye nokubuyekeza

Circuit amadlambi zenzelwe uphazamisa inethiwekhi kagesi lapho kokweqa ezisebenza izifunda zamanje futhi iDemo. Zivikela wiring futhi ixhunywe ku-ke abathengi overload futhi aqukethe izingongolo eyodwa kuya ezine. Three-pole wesifunda full yakhelwe ukuvikela wesifunda ezintathu okhombisa noma ngesikhathi esifanayo wiring ezintathu okhombisa. Uma omunye imigqa yengozi, zikhutshazwe ngokushesha ezintathu izingongolo.

Idivayisi ukuzixazulula imisebenzi elandelayo:

• kwesigaba inethiwekhi ukuvikelwa;
• ukuwohloka ekuvimbeleni wesifunda ingxenye;
• uzokhetha ekuvimbeleni uhambo okungagunyaziwe.

izici

I izici eyinhloko umshini - ukuthi ukalwe umthamo kuphulwa nesivinini usike-off. Basebenza kusuka izindlela ukuvala shaqa ezimbili: ezishisayo kanye kagesi. Eyokuqala kuvula wesifunda lapho short circuit, kanti eyesibili - isenzo zamanje okuqhubekayo kokweqa bokuzisholo. Gun ingasetshenziswa njengendlela inkinobho nge ukhiye control.

Kulinganiswe ngo umthamo kuphulwa

Inani Isici likhombisa eliphelele elivumelekile isekhethi wamanje lapho inkinobho uyakwazi unqamule wiring kumadivayisi exhunywe nalokho okungenani kanye. It is wabonisa phezu kwezindlu umshini futhi ukubaluleka:

• 4.5 KA - ukuze ivikele iDemo imigqa ensimini wesifunda abe nendawo yakhe yangasese, lapho ukumelana umugqa imithwalo kusukela substation ukuze asisikhulu kunenkosi 0.05 ohms;
• 6 KA - ukuvikela wemboni yokuhlala kanye nezindawo zomphakathi, lapho ukumelana umugqa akuyona ngaphansana 0.04 ohms;
• 10 KA - esetshenziswa kuvimbele ukulimala imigqa amandla emhlabeni substation.

ukuguqulwa letiphakanyisiwe 6 KA imodeli banakekele izifunda yasekhaya.

Isikhathi-zamanje izici

Lapho engalingani amandla ukusetshenziswa kubangelwa umthwalo ukushintshashintsha futhi amandla noma ukukhubaza amadivayisi wesifunda, kungase kube positives bamanga amadivayisi zokuzivikela ngenxa yokudlula zamanje esinesilinganiso. Ukuze unciphise amathuba nokucupha imishini esetshenziswa ne predetermined izici isikhathi samanje (BTX). Sepharamitha ubonisa isikhathi cutoff esikhungweni isilinganiso esithile zamanje nenani bokuzisholo. BTX omlandelayo.

1. B - i kagesi uhambo iyunithi Uhambo emva 0,015 imizuzwana mithathu ukwanda wamanje mayelana ukubaluleka bokuzisholo.
2. C - isici ezivamile lapho ukuvikeleka kwabangela ngokwandisa inani okuzisholo izikhathi 5. Machines Site ukukhanyisa nemishini ngokulinganisela inrush imisinga.
3. D - imishini yakhelwe ezinkulu inrush imisinga, njengalapho kubhayela kagesi, motors kagesi kanye namanye amadivayisi ezintathu okhombisa. Ikakhulu obusetshenziswa embonini.

Uhlolojikelele amadlambi

Umshini ixhunyiwe phakathi umthombo wamandla kanye wiring, okumele avikelwe. Three-pole wesifunda full yakhiwa contact amabhangqa amathathu, lapho ngamunye ixhunywe ku uchungechunge nge ezishisayo kanye kagesi uhambo amayunithi. isigaba okuzenzakalelayo ukukhubaza kuphela ngaphandle kokuphula hlangothi, okuyinto ayixhunyiwe ke. Uma udinga unqamule wire hlangothi, wasebenzisa imodeli amane isigxobo. Ngokuvamile, bajwayele sikokufaka main.

Amafulethi nasemakhaya abo esetshenziswa imishini ekilasini imithwalo ngokulinganisela. Amandla lwamanje zikhethwa amandla amadivayisi axhunyiwe, lapho embundwini kabili ihlelo ukuqeda positives bamanga.

imikhiqizo Okusatshalalisiwe IEK amafemu, ka EKF, Dek, INTES futhi "contactor". imikhiqizo Domestic babe nokwethenjelwa okwanele ngamanani ezifanele. Kabanzi imishini olusetshenziswe 16 A no 25 A. Imports ezibizayo, kodwa izinkampani owaziwa akhiqiza high onobuhle okuthembekile. On the switch okuzenzakalelayo emithathu isigxobo intengo kusuka izinkampani owaziwa zingase zihluke kakhulu, kodwa quality kuyavumelana.

lesivikelo nge ezintathu okhombisa zamanje kusetshenziswa khona uvo endlini futhi amathuluzi amandla professional nge voltage ka 380 V, isibonelo, i-othomathikhi emithathu isigxobo 100A inkinobho.

Lo mbuso kufanele luhambisane counter, uma imele emva inkinobho. Ngokuvamile akusiyo engaphezu kwengu-63 A. namandla kakhulu emithathu isigxobo wesifunda full isetshenziswa embonini.

Kusukela impendulo kanye neseluleko Electricians abanolwazi kusobala ukuthi imishini amahlelo overestimated noma kunjalo ayikwazi ukusetshenziswa. Lena ingozi yomlilo noma ukwehluleka insimbi.

Labo babusi abane-wire ezintathu okhombisa futhi zero ihlinzekwa emizini ukusebenza. Basuke kuyaqabukela esetshenziswa imishini ukalwe nganoma 380 V. Le izigaba ku iphaneli ukusatshalaliswa abahlukene. Lokhu kuveza 3 oseceleni nge voltage ka 220 V

Buhle imishini multi-pole ikhono lokuhlela kanyekanye ukulawula kolayini abaningana. Ngokufaka automatic emithathu isigxobo inkinobho 25a emithathu iyunithi elihambisana ukulawula amandla kungaba kwenziwe ku emugqeni ngamunye ngamunye. Esimeni short circuit eyodwa yazo wavala konke ngesikhathi esisodwa. Ngokuvamile, kulayini ngamunye ukufaka ezengeziwe wesifunda amadlambi owodwa esigabeni. Lapho omunye wabo ehluleka umsebenzi isigaba, okwandisa uhlelo nokwethenjelwa.

BA imishini uchungechunge

imishini Domestic ekhiqizwa uchungechunge AE kanye BA. Uhlobo lokuqala akasebenzi, futhi kuyaqabukela asetshenziswa. It has amandla eliphansi umzimba, ukuntuleka uxhumano lwe-Din-wesitimela. Ukuthola izinhlelo zokusebenza yasekhaya ezisilungele kangcono umkhiqizo uchungechunge VA ibalwa for imisinga kuze 63 A, isici B, C, D, kanye umthamo nasekuhlephuleni 4.5 KA.

Domestic emithathu isigxobo wesifunda amadlambi VA ihlangabezana ngokugcwele izidingo zanamuhla, ngenkathi ugcina intengo kakhulu ngaphansana onobuhle amazwe.

Ngokusho Izibuyekezo eziningi, onobuhle amazwe kutsi ube ngumuntfu lophelele at enjalo amanani aphezulu. Kodwa misfire, nakuba onobuhle yasekhaya kancane.

isiphetho

Three-pole wesifunda full kuyingxenye ebalulekile yesimiso kagesi ikhaya sika. Ukukhetha onobuhle ezibizayo, kufanele kukhunjulwe ukuthi lonke imishini kumele ezingeni elifanayo: Izintambo zikagesi ezisobala, ukushintshwa nezinyawo, okuhlangana amabhokisi, ukukhanyisa zalapho.

I izici eyinhloko imishini bekulungele ohlangothini front izindlu. Basuke akhethiwe kususelwe kusayizi wire futhi ubukhulu umthwalo axhunyiwe.
