Yonke malunga ontlantlu-ntathu sombane

phase-amathathu sombane esetyenziselwa ukuguqulwa ombane. Ifowuni isetyenziswa kwicandelo zoshishino iimfuno umbane kunye nendlu. Ngaphezu koko, izixhobo ezinjalo sele ngeenqanawa, ekubeni izixhobo zabo amandla yenziwa nge kumahlelo ahlukeneyo.

Ukubalwa kwesigaba ezithathu-sombane kwenziwe kuxwebhu ethile. Ngokusekelwe kwi-lwazi ezithathwe izixhobo ezifunekayo ikhethiwe. Ifowuni isetyenziswa kuphela xa ukusetyenziswa mveliso kodwa kwakhona ukuba zombane nendlu ekuvelisweni kwiisekethe ulawulo-elektroniki.

phase-amathathu sombane ukuba kwehliswe okanye bayavuswa, iinqobo inani ukuguqulela ezizimeleyo inani amathuba omabini jiko. Le fowuni ingakucela ukuba ndawonye ukusuka analogs kwisigaba emithathu-okanye babeqhuba engundoqo efanayo, isixa obhobhozayo otsalayo kwesigaba ngasinye kwisixhobo ezinjalo bekuya kuba zero.

Kuba abaguquli industrial uthotho lweemvavanyo eziqhutyiweyo phezu adibanayo iparameters ezichaziweyo. Amanyathelo Complex zokutshekisha iimpawu ifowuni iquka imilinganiselo ukungawi ngokubhijela ngamnye ubushushu ngokuphathelele emhlabeni, okanye phakathi ngokwezigaba. ombane Special isixhobo lisetyenziswe jiko ihlolwe umthondo yodwa. Ngaphezu koko, primary ngokubhijela na amandla kunye ixabiso ilinganiswa imveliso. Ukusebenzisa le amava, ngumlingani ukuguqulwa ibalwa.

iziphumo Umlinganiselo kufuneka zihambelane kumaxabiso aboniswe namaxwebhu akhaphayo, kungenjalo nesiguquli ontlantlu-ntathu yaliwe. Kubalulekile ukuqonda ukuba ufakelo ngomqokozo kunye nezixhobo nokucima 110 kV nangaphezulu akuvumelekanga ngaphandle ingcali kweliso kwi-mveliso, apho imveliso lwaqhutywa. Kulo mzekelo, uvavanyo kufuneka lwenziwe ngokulandela imigaqo eyamkelekileyo phambi lomntu abanobuchule.

phase-amathathu sombane elidityaniswe kwi "Inkwenkwezi" okanye "unxantathu". uqhagamshelo Star kufezeka esiludumbo oqhelekileyo zonke izigaba yaqala. Ndiqhuba unxantathu linqanaba ezilandelelanayo ezimbaxa kulo umsesane: ekupheleni kwesigaba sokuqala kuhambisana ekuqaleni ekupheleni wesibini nowesithathu yesibini kunye isiqalo nesiphelo yokuqala kunye ekuqaleni.

Ukuba transformer ontlantlu-ntathu elidityaniswe ngokungqinelana i "Star", iziqalelo nga Zenziwe gluhozazemlonnoy okanye bodwa cala (ebizwa ngokuba yi-node kokuxhuma eziphelweni izigaba). Kuba sokuvula nokucima eliphezulu-ombane, i hood okhethekileyo, nto leyo evumela umhlaba kunye razzemlyat cala. Noko ke, kule yokhuseleko sokuvula nokucima 0.4 kV wasebenzisa oyicinezelayo zero.

Kuba ukhuseleko imigca umbane kusetyenziswa abaguquli ombane, ngalo igunya kulawulwa. Banceda ukukhokela ukhuseleko saso ezimbombeni zaso kunye amaxabiso xa ucwangcisa izixhobo impendulo umahluko. Kwiimeko ezininzi, abaguquli zintathu zisetyenziswa kwisigaba ngasinye.

ngasinye Baye umphakathi ubuncinane ezimbini: enye enxulumene Delta evulekileyo, enye - inkwenkwezi. Star isebenza ukulinganisa ombane kule migca kwaye kufuneka unxantathu avulekileyo asilotyala yokhuseleko.

Namhlanje abaguquli ombane ezikhoyo kunye Punch yesithathu phantsi accounting. Ngayo, nina kokuxhuma zokubala. Njengomthetho jikelele, i-core wesithathu kananjalo lidibane inkwenkwezi. Le ukungcola iisekethe yolawulo ukusuka wesekethe wekhadi kuyanceda ukufumana ufundo luchaneke kakhulu, njengoko undoqo kweklasi accuracy imitha ngasentla.
