Notation e Electrics L N: izinhlobo izintambo, izici zabo

abakhiqizi Global endlu Imishini emhlanganweni imishini esetshenziswa ukufakwa izintambo anemibala. Leli yigama e L kagesi kanye N. Ngenxa umbala ngokuqinile kuchazwa, wizadi angase ngokushesha ukuthi yimaphi ama-babashayeli kuyinto isigaba, kuqanda phansi. Lokhu kubalulekile uma uxhuma noma unqamule imishini kusukela kwamandla.

izinhlobo amakhebuli

Uma uxhuma zikagesi, ukufakwa izinhlelo ezihlukahlukene ngeke akwenze ngaphandle babashayeli ekhethekile. Zenziwa aluminiyamu noma ithusi. Lezi izinto ukuqhuba ugesi kahle.

Okubalulekile! Aluminium izintambo Kumele uxhumeke nge aluminium kuphela. Ziyakwazi amakhemikhali asebenzayo. Uma uxhumekile ku-copper, lamanje ukudluliswa wesifunda uzoshesha ababhubhise. Aluminium izintambo axhunyiwe ngokuvamile nati nemishudo. Copper - ngokusebenzisa imishini. Kuyaphawuleka ukuthi uhlobo yokugcina umqhubi has ethile abalulekile - it is ngokushesha oxidized lapho zizwa emoyeni.

IBhodi uma endaweni okwenziwe namachibi zamanje iyeke ukudlula: ukubuyisela kwegezi, bentambo kufanele behlukene amathonya zangaphandle ngokusebenzisa kagetsi.

ngezigaba izintambo

Umqhubi kuhlanganisa omunye uninsulated noma eyodwa noma babashayeli ukushisa namakhaza ngaphezulu. Eyesibili uhlobo babashayeli camera nge igobolondo okhethekile-non-metallic. Lokhu kungafaka ukugujwa itheyiphu nangokuvikela emazombezombe noma ukwaluka okokusebenza fibrous. izintambo Bare Awunawo ezinengilazi zokuzivikela. Zisetshenziswa ukwakhiwa nezintambo zikagesi.

Ngokusekelwe osekushiwo, siphetha ngokuthi izintambo yilezi:

• avikelwe;
• olungavikelekile;
• amandla;
• obandayo.

Kufanele kusetshenziswe ncamashi njengoba beyalelwe. Ukusuka kancane kusukela izimfuneko ezisebenza kuholela zokugwema ukuphuka we kwamandla. Ngenxa yalokho, wesifunda imililo zenzeka.

Isikhundla isigaba, zero futhi phansi izintambo

Lapho ukukhweza amanethiwekhi kagesi injongo angasetshenziswa ekhaya nasezimbonini ngci amakhebuli. Zakhiwa eziningi babashayeli. Ngamunye wabo ababethi umbala ezifanele. Isikhundla LO, L, N e kagesi ukunciphisa isikhathi ukufakwa, futhi uma umsebenzi wokulungisa kunesidingo.

Ezichazwe ngezansi ku kagesi isiqu L N ihlangabezana ngokugcwele izidingo GOST 50462 futhi isetshenziswa ukufaka kagesi lapho voltage ifinyelela 1000 V Baye le earthed hlangothi. Leli qembu lihlanganisa zonke izinto zikagesi neze of zokuhlala, ehhovisi izakhiwo, izakhiwo kwezohwebo. Yini umbala esephepheni isigaba L, zero, N futhi phansi kufanele kuqashelwe uma ufaka amanethiwekhi kagesi? Asivume.

babashayeli isigaba

I-AC has babashayeli ukuthi amandla. Zibizwa ngokuthi babashayeli isigaba. Kusuka esiNgisini, igama elithi "Isigaba" kusho "umugqa", "wire asebenzayo" noma "wire bukhoma".

Ukuthinta umuntu kusukela uyembulile kusukela ukwahlukanisa isigaba umqhubi kungaholela ukusha okubi noma ngisho nokufa. Kusho ukuthini ukuba kagesi ukuqokwa L N? Kagesi kwendikimba isigaba izintambo kwasho Latin incwadi «L», futhi multi-core ikhebula ukwahlukanisa of umqhubi isigaba ababethi eminye imibala ezilandelayo:

• ezimhlophe;
• omnyama;
• onsundu ngaphansi;
• obomvu.

Izincomo! Uma nganoma isiphi isizathu ngogesi ophikayo ukuba yiqiniso kwale ndaba. ulwazi ubonisa anemibala ikhebula wire ukunquma ngaphansi voltage izintambo udinga ukusebenzisa low-voltage voltage inkomba.

zero Guides

Lezi izintambo kagesi zihlukaniswe ngezigaba ezintathu:

• umqhubi hlangothi.
• zero Avikelayo (umhlaba) babashayeli.
• umqhubi hlangothi, ngokuhlanganisa umsebenzi zokuzivikela futhi ukusebenza.

Kuyini ekubizweni kagesi izintambo L N? inethiwekhi Ngiphakathi nendawo noma umqhubi kokungathathi hlangothi izifunda ngamaketanga kagesi selisho Latin incwadi «N». Zero izintambo babashayeli ube umbala ezilandelayo:

• umbala oluhlaza okwesibhakabhaka obuphelele wonke ngaphandle inclusions;
• umbala oluhlaza okwesibhakabhaka obuphelele yonke imithambo ngaphandle inclusions ezengeziwe.

Kusho ukuthini L, N futhi PE kwezobunjiniyela kagesi? PE (N-RE) - umqhubi zokuzivikela, okuyinto ubude yonke we izintambo kufakwe imigqa ikhebula zipendwe kushintshana nephuzi.

Isigaba sesithathu ka-zero babashayeli (ren-wire), obuhlanganisa ukusebenza nemisebenzi zokuzivikela, has a notation umbala kagesi (L N). Ingabe ezinemibala eluhlaza okwesibhakabhaka, nemikhawulo yomhlaba ukuxhumeka imivimbo ophuzi.

Isidingo ukuqinisekisa wokugubha

Isikhundla LO, L, N e kagesi obandayo amanethiwekhi kagesi - umniningwane obalulekile. Indlela hlola ngokunemba umbala esephepheni? Ukuze wenze lokhu, udinga ukusebenzisa i-screwdriver inkomba.

Ukuhlola ukuthi yimaphi ama babashayeli kuyinto isigaba kanye zero ngosizo ebonisa ukufakwa kokumqoka kuphela, kudingeka uthinte yona sting ucezu eziyisisekelo wire. Uma LED ikhanyisa, ngemva kwayo kwaba khona ukuthintana siyinikeze umqhubi isigaba. Ngemva Ngokuthinta ukufakwa kokumqoka kuphela siyinikeze umqhubi hlangothi umphumela elikhanyayo ngeke.

Ukubaluleka babashayeli anemibala nokunamathela kakhulu imithetho yokusetshenziswa kwawo zizonciphisa ngesikhathi ukufakwa futhi amaphutha kagesi search, kuyilapho ukungamnaki kwalezi zimfuneko eziyisisekelo kuholela empilweni.
