Ukuqhagamshelana kwamandla amathathu wesigaba 380 volts

Ukubalwa kwamandla omthwalo wegridi yamandla kuyisiseko sokusebenza kwayo ngokuqhelekileyo. Kwiimfuno zasekhaya, i-voltage ye-220 volts isetyenziswa rhoqo. Kodwa akusoloko ixabiso leleyo lanele ukusebenza ngokuqhelekileyo kwazo zonke izixhobo zombane ezisetyenziswa ngombane. Iziganeko eziqhelekileyo xa kukho imfuneko yokutshintsha umbane ophezulu kunye neqondo eliphezulu - ii-380 volts.

Umehluko phakathi kwesakhiwo seenethiwekhi

Indlela yokusebenzisa igridi yamandla kagesi, ejoliswe kwiimfuno zangaphakathi, iquka ukubeka iibhola ezimbini - ngomthwalo kunye nendawo. Kule meko, umbane ovela phakathi kwawo ngu-220 volts. Oku kunokwaneleyo ukuqinisekisa ukusetyenziswa ngokuqhelekileyo kwezixhobo ezisemgangathweni zendlu kunye nezixhobo zokukhanyisa. Kodwa ngomthwalo owandayo, ikhebula lombane livutha, elikhokelela ekungabikho kwinqanaba elifutshane okanye ngomlilo.

Ukuze ugweme iimeko ezinjalo, kuyimfuneko ukuba ungabeki enye ngaphandle kwemiva emithathu egumbini. Kwinkoliso yamatyala, oku kunokwenzeka kunikezelwa kwizakhiwo zezindlu. Kwinkampani yabucala, unxibelelwano olunjalo lunokwenziwa kuphela ukuba kukho umbane wamandla osondeleyo kunye nezigaba ezintathu ezihlukeneyo. Ukongezelela, kubalulekile ukukhupha iincwadi zokugunyazwa ezivela kwinkampani yolawulo kunye nokuqinisekisa ukufakwa kwetambo kunye neengqayi ezine kwigumbi.

Kwiimeko ziphi i-380 volts

Isidingo sokudibanisa umbane wesigaba esi-3 singabangela iimeko ezininzi. Ukuba kukho izixhobo ezithile (ezinamandla), okanye ukuhambisa umthwalo kwinethiwekhi.

Kukho uluhlu oluthile lwamanethiwekhi ombane, apho kunokwenzeka ukutshintsha inani leenqanaba:

• Izindlu zangasese okanye iindawo zokuhlala.
• Iiholo zokuvelisa okanye izakhiwo zorhwebo ngenethiwekhi yombane.

Ngokwenza oko, ubuncinane ukwandisa okwexeshana kwinqanaba elifunekayo kwigumbi okanye indlu iyinkathazo enkulu. Ukuba ufuna ukudibanisa ii-voltage ezingama-380, kufuneka ube nesizathu esihle. Imveliso, ngokuqhelekileyo kwisigaba sokuyila, i-3-phase voltage isinikezelwa. Oku kubangelwa ngamandla aphezulu kwezixhobo kunye nomthwalo oqhubekayo kwinethiwekhi.

Izindlu zangasese kunye namafulethi

Xa kwakhiwa izakhiwo ezininzi zezindlu, ukubalwa kombane ogqityiweyo kwenziwa. Ngokusekelwe kule data, i-wiring yecandelo elifanelekileyo kunye nezixhobo zokhuseleko zifakwe. Ukuba, nangaliphi na isizathu, kukho ukunyuka kokusetyenziswa kwamandla, kuyacetyiswa ukwenza uxhumano lwe-380-volt.

Oku kungakho ngenxa yezi zinto zilandelayo:

• Ukufakwa kwezixhobo ezisemgangathweni zendlu - ishushu yokubilisa, inkqubo yolawulo lwemozulu, njl njl.
• Ukuqhuba imisebenzi yokulungisa okwethutyana, ngexesha lokusetyenziswa kombane kuya kwanda kakhulu kwaye umthwalo wenethiwekhi uza kwanda.

Kuxhomekeke kule nto, imvume ikhutshwe ukuba iguqule okwesikhashana okanye iguqule iiparitha zenethiwekhi, apho i-voltage ye-380 volts iba yintloko.

Inkqubo yokukhupha imvume

Kukho imithetho ethile yokutshintsha iiparitha zamanje kwinethiwekhi yombane. Ukuyila imvume kwisigaba sokuqala, amaxwebhu eprojekthi alungiselelwe . Ibonisa iintlobo zezixhobo kunye neempawu zazo. Ngokusekelwe kule nkcukacha, inkampani yolawulo kufuneka inikeze imeko yezobugcisa kwi-voltage ye-380 volts. Indlela yokudibanisa kunye neyiphi imigqa yamandla kufuneka isetyenziswe kule nto, injini iyanquma.

Emva koko, isenzo senziwe, esichaza ezi zinto zilandelayo:

• Iphakheji efunekayo yamaxwebhu obunikazi ngezindlu (indlu).
• Iprojekti yobugcisa, ekhankanywe ngasentla.
• Ingxelo, iqulunqwe ngokusekelwe ekuqhutyweni ngabameli beenkampani ukuqinisekiswa kweempawu zeempawu kunye nezixwebhu eziqhotyoshelwe kuyo.

Ukuba iimfuno zivumelekile-ukwanda okwenziwe kwindlela yokusetyenziswa kwamandla ngokuhambelana nemigangatho kwizatifikethi sezixhobo, ngoko kukho uxhulumaniso kunye nokuxhunywa kwama-voltage angu-380.

Kwizindlu zabucala, inkqubo iyahluke. Ukuba kumgama ongaphantsi kwe-500 m ukusuka kwisakhiwo kukho umgca wesigaba-3, ngoko yonke isebenzisana nokuqhagamshelana kwayo (emva kokuvunyelwa kwamaphepha eemvume) kwenziwa yinkampani yolawulo. Ngaphandle koko, ukwandisa ukuxhatshazwa kwindlu akunakwenzeka.

Ukusetyenziswa kwezoshishino kunye nezorhwebo

Kwizakhiwo kunye nezakhiwo ezineemithwalo ephezulu rhoqo, i-voltage ye-380 volts isetyenziswe ngokungagqibekanga. Oku kusebenza ngokuthe ngqo kuzo zonke izibonelelo zoshishino nezorhwebo. Ukunikezelwa kwamandla okuqhelekileyo kwizicwangciso, iinkqubo zokubeka iliso kunye nokuhambisa umbane zinikezelwa, kuxhomekeke kumthwalo kwindawo ethile. Ukwenza uxwebhu olunjalo luyilo lulawulwa yiinkampani ezizodwa ezifunekayo ukuba ziqinisekiswe.

Ngaba kulufanelekile ukuchitha umgca wesigaba se-3 kwindlu yangasese okanye indlu yangaphambili? Oku kunokwenzeka kuphela ukuba imigaqo yoyilo ibonwa, apho iindidi zezixhobo zombane kunye neempawu zazo kufuneka ziboniswe.
