Kumongozi, kubalulekile ukuthi ube neqiniso elincane ngovoltaji phakathi kophase kusistemu yenhlango yethri. Lokhu voltaji teknoloji kunezimboni eziningi, futhi isetshenziswa kakhulu emisebenzini engaphezu kweminye. Uvoltaji phakathi kophase kusistemu yenhlango yethri uyizwa nguqhawe. Akulungeleke sibabazise ngendlela enjalo ukuze siyize ngempela.
Umsebenziso wokwesekhwa kwe-teknoloji yovoltaji yezinhlanga ezintathu kukusiza izimoto nezinye izixhobo ezingenziyo kakhulu. Ngokuphambene nesistemu yenhlangothi eyodwa, ivoltaji yezinhlanga ezintathu inikeza umphumela onjalo okubalulekile kakhulu emisebenzini yasebhakabhaka. Leli teknoloji futhi kubangela ukusebenza kahle kwemikhina ngokunciphisa izihlanguzelo nokuba izinkinga zibe namandla. Izinhlanga ezintathu zashaywa futhi ngokunakekela amandla aphezulu futhi kakhulunywa kuzindawo zasebhakabhaka njengezithuthi ezingenziyo kakhulu. Ngokuvamile, teknoloji yovoltaji yezinhlanga ezintathu inikela izinkinga eziningi kodwa kungekosi kancane xa kulinganiswa nazo ezinye izinhlobo zomthelelo. Kumaqiniso abadingayo ukuhlelwa kwovoltaji, izinto njenge 15KVA Zintathu Iiphase 380v ac Amathethweni avr/Ampumulo Esikhundleni/Stabilizer zishumayelwa kakhulu ukuze kube nemisebenzi embalimbali.
imithetho Yezinhlanu (II) Ukuhamba Kwezinhlanu Ukuxhumana okunye, kungahlanganiswa ngaphakathi kwe-delta noma i-star futhi ukuxhumana kwalokhu kuzobalwa ngokulinganayo ku- The cube root of line voltage ekupheleni kwe-Star connection Ngakho-ke uma muntu afuna ukuxhumana phakathi kwezinhlanu kusukela emgodi azidinga ukumisa ngama-1.(ExpectedConditions: e^(- i x )= Cosx --isin x & e^(i x)=Cosx +i sinx Itholakala ngu gaurav ngomhlaba, Epreli 23, 2007). Ukuze uthole ukuxhumana phakathi kwezinhlanu, umise ukuxhumana kweline ngama-1.732. Ngakho-ke, kuline voltage yezinkulungwane ezingu-100, uzoba nezinhlanu ezingu-100 x √3 ≈ 173 volts. Lokhu kubalwa kubalulekile ekubekeni phawula ukuthi izixhobo zifinyelela kanjani ukuxhumana okufanele noma lapho kusetshenziswa ngamathuba akhe amanelisiwe. Uma bazi ukuthi kanjani kufanele kube khona ukuxhumana phakathi kwezinhlanu imithetho yezinhlanu ezintathu, abasebenzi basebhizinisi bangazivikela izinkinga ezinokuthutha futhi bazilinde izixhobo zabo zisebenze njengoba kufanele. Ukuze kube khona ukuxhumana okujwayelekile kwalokho, izinto ezifanayo ne- Umfundisi wemilango usaleshi SBW-F-200K isifase esine esiphezulu somsebenzi wemfuyo manikeza inkxaso emhle.
Phindula ukuthatha izixhumanisi ezivimbela ivolthiji kusobala kumele ukhethe izinto ezifana nokuthethwa kahle, igredhi futhi imibiko yomsebenzisi. Ukuqasha izixhumanisi ezinobulungiswa indlela eyodwa yokuthola izixhumanisi ezinobulungiswa kukuba ufuna khona ikhompuyutha enempilo yokuthengisa i-equipment yesilawuli. Amawebhusayithi athi HEYUAN anamathuba amaningi avolthiji afana netransformer, iswitchgear, namatholi volthiji. Ungafunda futhi imibiko yabantu abathengayo njengendlela yokuchaza uhlelo lwesilinganiso nesivinini ungakwenzela kusukela phansi kumntu othile ngaphambi kokuthenga. Futhi, ukuqhoboka abasebenzi besilawuli besebenzisa izimpendulo zabo kungakusiza ukuthole umthengi ongavimbela okhokhelwe kuye konke akhokha kakhulu. Hlupha ukubheka izinhlahla ezithile futhi Amaphuva wokuqala Emtsha 15K & 20K Input Stabilizer 45-280V AVR Amaphuva Wokugcina Lomsebenzi Olungaphandle kweGebhu AC Current yizinqubo ezihle zokulawula ivolthiji.
Ukulinganisa okufanele kwe-voltage phakathi kwezindawo kumashini yasezindaweni zokusebenza kuyinto eqinisekiswa ngizidingo lenqanaba ngalinye lezixhobo ezisetshenziswayo. Ngokubanzi, izixhobo zezindawo zokusebenza ziyisebe sezinhlobo ezintathu futhi ne-voltage eyithile ekhuphuka phakathi kwe-208v kuya ku-480v. Izi-voltage ezihlukene kangaka ekuhlengahlengeni kwesifuba zilandelwa: 208V, 240V, kanye no-480V – ngenkathi izixhobo ezikhulu ziyisebe esingcono sokungu-480 volts. Ngakho-ke, kumele uchazeke amasethingi akunye kunye nokunye kwezixhobo ukwazi ukulinganisa okufanele kwezindawo zokusebenza. Ukukhetha i-voltage efanele kwezixhobo zesifuba kuyakhona kubaluleke kakhulu ekukhundleni izixhobo ukuthi zingasebenze futhi uqiniseke ukuthi umshini wakho usebenza ngendlela efanele.
