Ngenkqubela phambili eqhubekayo yetekhnoloji, imfuno yezixhobo zombane ikhula imihla ngemihla. Kwaye elinye lamacandelo abalulekileyo, ucingo lokumelana, ludlala indima ebalulekileyo. I-Resistance wire licandelo elisetyenziselwa ukulawula okwangoku kunye ne-voltage, edla ngokufunyanwa kwizixhobo ezahlukeneyo zombane. Eli nqaku liza kwazisa iiparitha zokuchazwa kweengcingo zokumelana.

I-Resistance wire yintambo encinci eyenziwe ngezinto ezikhethekileyo ezinokuvelisa iimpawu zokumelana. Ngokuqhelekileyo zenziwe ngesinyithi okanye i-alloys, njenge-nickel chromium alloy, i-iron chromium aluminium, njl. Ngokweemfuno ezahlukeneyo zesicelo, iingcingo zokumelana zinokuba nobubanzi obuhlukeneyo, ubude, kunye nemilinganiselo yokumelana.

Okokuqala, makhe sijonge ububanzi bocingo lokumelana. Ububanzi bubude becandelo lomgca we-cross-sectional of the resistance wire, ngokuqhelekileyo ulinganiswe ngamamilimitha (mm). Ubungakanani bobubanzi buchaphazela ngokuthe ngqo i-conductivity yocingo lokumelana. Ngokuqhelekileyo, i-diameter encinci, inkulu ixabiso lokumelana nocingo lokumelana; Ubuninzi be-diameter, encinci ixabiso lokumelana nocingo lokumelana. Ngoko xa ukhetha ucingo lokuxhathisa, kuyimfuneko ukugqiba ubungakanani bobukhulu obusekelwe kwiimfuno ezithile zesekethe.

Okwesibini, ubude bocingo oluchasayo lukwayinto ebalulekileyo yokuchaza ipharamitha. Ubude bumisela ubungakanani obupheleleyo bocingo lokumelana, ngokuqhelekileyo lulinganiswa ngeemitha (m). Ubungakanani bobude ngokuqhelekileyo bunqunywe yinkqubo yesiphaluka, kwaye ukukhetha ubude obufanelekileyo ngokusekelwe kwiimfuno zangoku kunye ne-voltage kunokuqinisekisa ukusebenza okuzinzile kocingo lokumelana.

Ekugqibeleni, ixabiso lokumelana nocingo lokuchasana luyi-parameter engundoqo. Ixabiso lokuchasana limele iqondo lokuchasana nocingo oluchasayo ukuya okwangoku, ngokuqhelekileyo lilinganiswe kwi-ohms (Ω). Ixabiso lokuchasana linokufezekiswa ngokulungelelanisa izinto, ububanzi, kunye nobude bocingo lokumelana. Kwizicelo ezisebenzayo, sinokuhlangabezana neemfuno zeesekethe ezahlukeneyo ngokudibanisa iingcingo zokumelana nemilinganiselo eyahlukeneyo yokumelana.

Ukongeza kwiinkcazo ezintathu eziphambili ezikhankanywe ngasentla, kukho nezinye izinto ezichaphazela ukusebenza kocingo lokumelana. Ngokomzekelo, ukukhethwa kwezinto eziphathekayo kunempembelelo enkulu ekuzinzeni nasekuqhubeni iingcingo zokumelana; Ukunyangwa komphezulu kunokuphucula ukuxhathisa umhlwa kweengcingo zokuchasa; Ubushushu be-ambient bunefuthe ekusebenzeni kokusebenza kweengcingo zokumelana, njalo njalo.

Isishwankathelo, ukukhethwa kweenkcukacha zocingo zokumelana kufuna ukuqwalaselwa ngokubanzi kwezinto ezahlukeneyo. Ngokweemfuno zesekethe, ukugqiba ububanzi obufanelekileyo, ubude, kunye nexabiso lokumelana, ngelixa uhlawula ingqalelo ekukhethweni kwezinto eziphathekayo kunye nokuphathwa kwendawo, kunokuqinisekisa ukusebenza okuqhelekileyo kocingo lokumelana nezixhobo zombane.

Ngenkqubela phambili eqhubekayo yetekhnoloji, imfuno yokuxhathisa iingcingo kwizixhobo zombane nayo ihlala ivela. Kwixesha elizayo, sinokubona kwangaphambili ukuba iingcingo zokuxhathisa ziya kuba zincinci, zizinze, kwaye zisebenze ngakumbi. Nokuba zii-smartphones, iikhompyuter, iimoto, okanye ezinye iimveliso ze-elektroniki ezitsha, iingcingo zokuxhathisa ziya kuqhubeka zidlala indima ebalulekileyo, ezizisa lula kunye nolonwabo ebantwini.

Oku ngasentla kukwazisa kwiinkcazo kunye neeparitha zeengcingo zokumelana. Ndiyathemba ukuba eli nqaku linokubonelela abafundi ngokuqonda okunzulu kweengcingo zokumelana kunye nokubonelela ngesikhokelo kwizicelo ezisebenzayo. Nangona iingcingo zokuchasana zincinci, zidlala indima ebalulekileyo kwizixhobo zombane, ukukhuthaza ukuphuhliswa kobuchwephesha kunye nenkqubela phambili yoluntu. Masijonge phambili ekudaleni amathuba amaninzi okuphuhliswa kweengcingo zokuxhathisa kwixesha elizayo!
