Wire kwesigaba esiphambanweni ukufakwa wiring

Ugesi is ngakho siqine ezimpilweni zethu ukuthi izimpilo zethu sengathi transfixed yi okungazelelwe ukunikezela ngogesi kwenzeka usike, futhi sibheke phambili kwaze kwaba yilapho kabusha. Sizungezwe lenqwaba zikagesi ezahlukene ukuthi axhunyiwe kunethiwekhi yakho yasekhaya noma ngqo ngokusebenzisa kugesi odongeni, noma ngokusebenzisa zokunweba, noma esithwele.

Ngezinye izikhathi kuye kudingeke baqhube ukukhanya egalaji noma ezinye izindlu, esikhundleni wire noma wenze okuzenzela isandiso intambo. Noma-ke kuyadingeka ukubala kunani alikhulu lamadivayisi kungenziwa kanyekanye afakwe eyodwa tee ukuthi akukhona sekuqala ukufudumala wire futhi kwaqubuka umlilo ngenxa short circuit. Ezimweni ezinjalo kubalulekile ukwenza i-ekubalweni wire osayizi ngesikhathi esifanayo ngaba nokuzethemba ukuphepha wiring ezifakiwe.

Yini ikhebula ukukhetha?

Akusiyo imfihlo ukuthi ithusi has a ukumelana ngaphansana aluminium, ngakho uma iqhathaniswa ikhopha ne-aluminiyamu wiring, lapho wire efanayo esigabeni cross, esimweni sokuqala, umthwalo ovumelekile izoke emikhulu. wire yethusi kunamandla, ethambile futhi akusho sokudiliza ezindaweni inflexion. Futhi, nethusi kancane ekuthonyweni namachibi futhi ukugqwala. Inzuzo kuphela aluminium wire izindleko zawo, okuyinto kancane kathathu noma kane kunokuba zethusi.

Ukubalwa umqhubi cross-ingxenye amandla

Noma yimuphi izintambo zikagesi kumelwe kuvumelane umthwalo ezixhunywe kulo. usayizi Wire ibalwa kusukela esiphezulu Ukushisa babashayeli. Inani kuncike Ukushisa amandla Amaplaki kagesi. Ngakho, by kuhlaziywa esiphezulu kungenzeka umthamo isamba amayunithi zasendlini, kungenzeka ukuba anqume ukuthi yikuphi okufanele ibe sigaba wire. Ngo practice, kulula ukuyisebenzisa wokubala intanethi noma amatafula ekhethekile eziqukethe ulwazi mayelana lamanje esithwele umthamo ikhebula.

Kanjani ukuhlola ubukhulu wire?

Njengoba izintambo ngokuvamile ube ukuma isiyingi cross-Sectional, endaweni locezu ubalwa kusetshenziswa ifomula:

S = π x d² / 4 noma S = 0.8 x d², lapho
S - endaweni Sectional babashayeli e mm.kv;.
π - 3,14;
d - wire ubukhulu mm.

Lokucabanga isibonelo ukuthi ubukhulu wire 1.3 mm., Bese S = 0.8 0.8 • • 1,3² = 1.3 x 1.3 = 1,352 mm.kv.
Uma bentambo yakhiwa babashayeli eziningana, kubhekwa kwesigaba esisodwa core kanye siphindwe ngesibalo Imininingwane ugongolo. I ububanzi ngokuvamile kulinganiswa nge caliper, kepha uma kungenjalo, khona-ke silingane line evamile. Kulokhu, lo uvalwe nilimaza kwi ipensela mayelana 10-15 ematfuba emazombezombe kulinganiswa umugqa ubude sokuhlukanisa ukubaluleka etholwe inani ematfuba.

Kunoma eletromontazhnyh imisebenzi kudingeka sikhumbule ukuthi ugesi akakubekezeleli inganakiwe futhi ibekwe endaweni akusho amaphutha. ukuphepha kagesi nokwethembeka - yilokhu okufanele ngaso sonke isikhathi sifune lapho wenza noma yisiphi izintambo zikagesi e ifulethi, cottage noma endlini.
