Ukugcina isistimu yokubhala ikhodi yombala efanele kuqinisekisa izintambo eziphephile nezilula. Ngezinye izikhathi lokhu kungavimbela ingozi ebulalayo. Noma ngezinye izikhathi kungakusiza ukukugcina uphephile ngesikhathi sephrojekthi. Yingakho namuhla sikhetha isihloko esilula esinezimpendulo ezimbili. Ingabe intambo emnyama iphozithivu noma inegethivu?

Ngokuvamile, i-polarity yocingo olumnyama incike ohlotsheni lwesifunda. Uma usebenzisa isekethe ye-DC, intambo ebomvu ingeyamanje ephozithivu futhi intambo emnyama ingeyamanje eyinegethivu. Intambo yaphansi kufanele ibe mhlophe noma impunga uma isekethe isekelwe phansi. Kusekhethi ye-AC, intambo emnyama iphozithivu futhi intambo emhlophe inegethivu. Intambo yaphansi iluhlaza.

impendulo eqondile

Uma ungakaqiniseki nge-polarity yocingo olumnyama, nansi incazelo elula. Kumasekhethi e-DC, ucingo olumnyama luwucingo olunegethivu. Kumasekhethi e-AC, intambo emnyama intambo ephozithivu. Ngakho-ke, kubalulekile ukunquma uhlelo lwesifunda ngaphambi kokunquma i-polarity yocingo olumnyama. Nokho, abantu abaningi badideka ngokushesha. Ukwenza kanjalo kungase kubangele ukushaqeka kukagesi noma ukulimala kwezinto zikagesi.

Izinhlobo ezahlukene zamakhodi ombala wezintambo

Kuye ngohlobo lwesekethe, ungase uhlangane namakhodi amaningana ombala wezintambo. Ukuhlonza lawa makhodi ombala wezintambo kuzokuzuzisa ngezindlela eziningi. Okubaluleke kakhulu, kuzoqinisekisa ukuphepha. Lapha ngithemba ukuxoxa ngamakhodi ombala wezintambo ze-DC kanye ne-AC.

DC Power Wire Color Codes

I-Direct current, eyaziwa nangokuthi i-direct current, ihamba ngomugqa oqondile. Nokho, amandla e-DC awakwazi ukudluliselwa ebangeni elide njengamandla e-AC. Amabhethri, ama-fuel cell namaseli elanga yimithombo yamandla kagesi e-DC evame kakhulu. Kungenjalo, ungasebenzisa isilungisisi ukuguqula i-AC ibe yi-DC.

Nawa amakhodi ombala wezintambo zamandla e-DC.

Intambo ebomvu yamanje ephozithivu.

Intambo emnyama yamanje eyinegethivu.

Uma isekethe ye-DC inocingo oluphansi, kufanele lube mhlophe noma olumpunga.

Bese ukhumbula: Imvamisa, amasekethe e-DC anezintambo ezintathu. Kodwa ngezinye izikhathi uzoba nezintambo ezimbili kuphela. Intambo engekho iphansi.

Amakhodi Ombala Wentambo Yamandla E-AC

I-alternating current, eyaziwa nangokuthi i-alternating current, ivame ukusetshenziswa ezindlini nasemabhizinisini. Amandla e-AC angashintsha indlela ngezikhathi ezithile. Singabhekisela ekushintsheni kwamandla njengamagagasi e-sine. Ngenxa ye-waveform, amandla e-AC angahamba kude kunamandla e-DC.

Kuma-voltage ahlukene, uhlobo lwamandla e-AC luzohluka. Isibonelo, izinhlobo zamandla kagesi ezivame kakhulu ngu-120V, 208V kanye no-240V. Lawa ma-voltage ahlukene eza nezigaba eziningi. Kulokhu okuthunyelwe, sizokhuluma ngamandla ezigaba ezintathu.

Amandla ezigaba ezintathu

Lolu hlobo lwamandla e-AC lunezintambo ezintathu ezibukhoma, intambo eyodwa emaphakathi, kanye nentambo yaphansi eyodwa. Ngenxa yokuthi amandla avela ezintanjeni ezintathu ezihlukene, lolu hlelo lwezigaba ezi-1 lungaletha amandla amaningi ngokusebenza kahle kakhulu. (XNUMX)

Nawa amakhodi emibala yezintambo zamandla e-AC.

Intambo yesigaba 1 kufanele ibe mnyama, futhi leyo ntambo emnyama eshisayo esiyishilo ekuqaleni esihlokweni.

Intambo yesigaba 2 kufanele ibe bomvu.

Intambo yesigaba sesi-3 kufanele ibe luhlaza okwesibhakabhaka.

Intambo emhlophe intambo emaphakathi.

Intambo yaphansi kufanele ibe luhlaza noma ibe luhlaza ibe nemigqa ephuzi.

Bese ukhumbula: Izintambo ezimnyama, ezibomvu neziluhlaza ziyizintambo ezishisayo ekuxhumekeni kwezigaba ezintathu. Nokho, izintambo ezine kuphela ezingatholakala ekuxhumekeni kwesigaba esisodwa; okubomvu, okumnyama, okumhlophe nokuluhlaza.

Ukufingqa

NgokweKhodi Kagesi Kazwelonke (NEC), amakhodi ombala wezintambo angenhla angamazinga ezintambo zase-US. Ngakho-ke, landela le mihlahlandlela noma nini lapho wenza iphrojekthi yezintambo. Kuzokugcina wena nekhaya lakho niphephile. (2)
