Kwithiyori, isisiko senkqubo kufuneka sithobele iiparamitha ezichaziweyo. Umzekelo, ukuba kubonisiwe ekumakisweni kwentambo yi-3 x 2,5, emva koko icandelo lenkqubo inqamleza ingama-2,5 mm2. Ngapha koko, kuyavela ukuba ubukhulu obahlukeneyo bungahluka nge-20-30%, kwaye ngamanye amaxesha ngaphezulu. Yintoni esongela ntoni? Ukuhamba kakhulu okanye ukubeka usodwa ngazo zonke iziphumo ezilandelayo. Ke ngoko, ngaphambi kokuba uthenge, kunqweneleka ukufumana ubungakanani becingo ukumisela icandelo layo lomnqamlezo. Kuthathelwa njani ngokuthe ngqo icandelo lomnqamlezo locingo oluyingozi kwaye luya kufumanisa ngakumbi.
Njani kwaye njani ukulinganisa ububanzi becingo (wire)
Ukulinganisa ububanzi becingo, i-caliper okanye i-micrometer yayo nayiphi na indlela (yoomatshini okanye i-elektroniki) ifanelekile. Kulula ukusebenza nge-elektroniki, kodwa ayizizo zonke. Kuyimfuneko ukulinganisa impilo entle ngaphandle kokuhlala yedwa, ngenxa yoko ishukunyisiwe okanye isuse isiqwenga esincinci. Oku kungenziwa ukuba umthengisi uvunyelwe. Ukuba akuthethi, thenga isiqwenga esincinci sokuvavanya kwaye uchithe imilinganiselo kuyo. Kwi-inshunshini, umqhubi wesifundo ulinganisa ububanzi, emva koko kunokwenzeka ukuba uqonde iCandelo le-wire kwisayizi.
Imilinganiselo yobungakanani be-micromitha yocingo ichanekile ngakumbi kune-caliper yoomatshini
Sisiphi isixhobo sokulinganisa kweli meko bhetele? Ukuba sithetha ngeemodeli zoomatshini, emva koko i-micrometer. Ichanekile imilinganiselo ephezulu. Ukuba sithetha ngeendlela zokhetho lwe-elektroniki, emva koko iinjongo zethu zombini zinika iziphumo ezinokuthenjwa.
Ukuba akukho calir, okanye i-micrometer, ithimba i-screwdriver kunye nomlawuli. Kuya kufuneka sicoce isiqendu esihle somqhubi, ngaphandle kokuthenga iphethini yovavanyo ngeli xesha alithintelwa. Ke, susa i-bodwares kwi-wiires 5-10 cm. Hlamba intambo kwinxalenye ye-cylindwricriver. I-colals ibekwe ecaleni kwenye, ngaphandle kokucocwa. Zonke izinto ezijikajikayo kufuneka zigqibe, oko kukuthi, "imisila" yeengcingo kufuneka ichithwe kwicala elinye-phezulu okanye ezantsi, umzekelo.

Ukufumanisa ububanzi be-wire usebenzisa ibhunga
Inani leejika alibalulekanga - malunga ne-10 le-10. Kunokwenzeka okanye ngaphantsi, ukwahlula lula. Ukuphosajika, emva koko sebenzisa umoya obangelwa ngumlawuli, ulungelelanise ukuqala komjikelo wokuqala onamaphawu (njengakwifoto). Linganisa ubude bendawo ehlala i-wire, emva koko iyahlulahlula inani lokujika. Fumana ububanzi becingo. Kulula kakhulu.
Umzekelo, sijonga ukuba ubukhulu becala locingo oluboniswe kwifoto engentla. Inani leenguqu kule meko yi-11, ithatha i-7.5 mm. Sahlulahlula 7.5 ukuya kwi-11, sifumana i-0.68 mm. Oku kuya kuba bubukhulu beli ngoocingo. Okulandelayo, unokukhangela icandelo loloqhubi.
Sikhangela icandelo le-wire ububanzi: ifomula
Iingcingo kwintambo zinesangqa kwicandelo lomnqamlezo. Ke ngoko, kwisibanga, sisebenzisa ifomula yendawo yesangqa. Inokufunyanwa isebenzisa i-radius (isiqingatha sedayamitha elilinganayo) okanye ububanzi (jonga iFomula).
Fumana icandelo lomnqamlezo lwe-wire ububanzi: ifomula
Umzekelo, sibala indawo enqamlezayo yomqhubi (ucingo) ngobungakanani obubalwe ngaphambili: 0.68 mm. Masiqale sisebenzise ifomula kunye ne-radius. Okokuqala sifumana irediya: Sahlulahlula umda wayo. I-0.68 mm / 2 = 0.34 mm. Okulandelayo eli nani sibambe endaweni yefomula
S = π * r2 = 3,14 * 0.342 = 0.36 mm2
Kuyimfuneko ukubala ngale ndlela: Okokuqala siya kwakhiwa kwisikwere 0.34, saphindaphinde ixabiso elifunyenwe ngu-3.14. Fumana icandelo lomnqamlezo sale wire 0.36 imilitha ye-millimitha. Esi singcingo esicekeceke kakhulu, esingasetyenziswanga kwiinethiwekhi zamandla.
Mabale i-cable yecable ubukhulu becala usebenzisa i-formula yesibini yefomula. Kufanele ukuba intsingiselo efanayo. Umahluko unokuba kumawakawaka eesabelo ngenxa yokujikeleza ezahlukeneyo.
S = π / 4 * D2 = 3.14 / 4 * 0,482 = 0,485 = 0.36 mm2
Kule meko, sahlulahlula inani 3.14 ukuya kwezine, siya kwakhiwa kwisikwere, amanani amabini afunyenwe ngokwahlukileyo. Sifumana ixabiso elifanayo, njengoko kufanele kube njalo. Ngoku uyayazi indlela yokufumanisa intambo yekhebula ubukhulu. Yeyiphi kwezi fomula ilungele wena, kwaye isebenzise. Akukho mahluko.

Itheyibhile ehambelana needayimitha zeengcingo kunye nendawo yazo yecandelo
Ukuziphatha kwiindawo zokuhlala okanye kwintengiso akusoloko kufuna okanye unalo ithuba. Ukuze ungachithi ixesha malunga nokubala okanye ukungasebenzi kakuhle, ungasebenzisa itafile yokuvumelana kweedayimitha kunye namacandelo ee-bimes apho kukho imilinganiselo exhaphakileyo. Ingabhalwa kwakhona, iprinte kwaye igcinwe kunye nawe.
| I-Diamertor | ICandelo leKhuqu |
|---|---|
| I-0.8 mm | I-0.5 mm2 |
| I-0.98 mm | I-0.75 mm2 |
| I-1,13 mm | I-1 mm2. |
| I-1.38 mm | I-1.5 mm2 |
| I-1.6 mm | I-2.0 mm2. |
| I-1.78 mm | I-2,5 mm2 |
| 2.26 mm | 4.0 mm2 |
| I-2.76 mm | I-6.0 mm2 |
| I-3.57 mm | I-10.0 mm2. |
| 4.51 mm | I-16.0 mm2. |
| 5.64 mm | 25.0 mm2. |
Ungasebenza njani nale tafile? Njengommiselo, kwiintambo kukho imakisha okanye i-tag apho iiparameter zayo zibonisiwe. Kukho i-camaki yentambo, isixa sexesha eliphilayo necandelo labo lokuwela. Umzekelo, ukuqhuba i-2x4. Sinomdla kwiiparamitha zemithambo. Kwaye la manani amileyo emva kophawu "x". Kule meko, kuchazwe ukuba kukho umqhubi obini onesiqendu secandelo eli-4 mM2. Ke siya kutshekisha ukuba olu lwazi luyinyani.
Ukujonga, ukulinganisa ububanzi bayo nayiphi na indlela echaziweyo, emva koko ibhekisele kwitafile. Ibonisa ukuba ngecandelo elinjalo kwiimilimitha ezine ezisikwere, ubungakanani becingo kufuneka lube yi-2.26 mm. Ukuba unemilinganiselo efanayo okanye i-10 irestimenti ikhona, njengezixhobo ezingezizo ezilungileyo), yonke into ihamba kakuhle, ungayithenga le seble.
Ubungakanani obuchaziweyo bude bungasoloko buhambelana nenyani.
Kodwa okuninzi ngakumbi eyona incinci yabaqhubi iphantsi kakhulu kuno. Emva koko unendlela ezimbini: Khangela ucingo lomnye umenzi okanye uthathe icandelo elikhulu lomnqamlezo. KuYe, kuya kufuneka, kuya kufuneka uphele ngaphezulu, kodwa ukhetho lokuqala luya kufuna ixesha elincinci, kwaye ayisiyonto oya kuba nakho ukufumana intambo ye-goby ehambelanayo.

Inketho yesibini iya kufuna imali engaphezulu, kuba ixabiso elibonakalayo lixhomekeke kwicandelo elibhengeziweyo. Nangona, hayi inyani-intambo elungileyo eyenziweyo kuyo yonke imigangatho isenokubiza kakhulu. Oku kuyaqondakala - iindleko zobhedu, kwaye, rhoqo, kunye nokuzahlula, ngelixa zihambelane netekhnoloji nemigangatho, enkulu kakhulu. Ke ngoko, abavelisi kunye neChitryot, ukunciphisa ububanzi beengcingo - ukunciphisa ixabiso. Kodwa olondolozo olunjalo lunokujika lube yingxaki. Qiniseka ukuba ulinganisa ngaphambi kokuthenga. Nditsho nabathengisi abaqinisekisiweyo.
Kwaye kwakhona: ukuhlola nokuduma. Ifanele ibe yinto eqinileyo, iqinile, inobungqingqwa obufanayo. Ukuba, ukongeza ekutshintsheni ububanzi, ingxaki ikwayinxalenye yodwa-jonga intambo yomlo. Ngokubanzi, kuyacetyiswa ukufumana iimveliso ezihlangabezana neemfuno ze-Gost, kwaye zenziwanga kuloo nto. Kule meko, kukho ithemba lokuba intambo okanye icingo liza kukhonza ixesha elide nangaphandle kweengxaki. Namhlanje akukho lula ukwenza, kodwa ukuba uqhawula umtshato kwi-wiring endlwini okanye uqhagamshele umbane ukusuka kwisithuba, umgangatho ubaluleke kakhulu. Ke ngoko, kusenokwenzeka ukuba ukhangele.
Ungawubona njani icandelo lomnqamlezo kwi-wire echithiweyo
Ngamanye amaxesha ooguli bezikolo zisetyenziswa-zibandakanya iingcingo ezininzi ezimanyeneyo. Ungabala njani icandelo lomnqamlezo kwi-wire ububanzi kule meko? Ewe, naye. Yenza imilinganiselo / ukubala kwi-wire enye, cinga ngenani labo egameni, emva koko uphindaphindile ngeli nani. Apha uza kufunda indawo yecandelo lecandelo le-wire eqingqiweyo.
Icandelo lomnqamlezo le-wire eqingqiweyo lithathwa njengento efanayo
