Umehluko phakathi kukagesi wesigaba esisodwa, ugesi wesigaba ezimbili, kanye nogesi wesigaba ezintathu

Ugesi wesigaba esisodwa kanye nogesi wesigaba ezimbili yizindlela ezimbili ezahlukene zokuphakelwa kwamandla. Zinomehluko omkhulu ngesimo kanye ne-voltage yokudlulisela kagesi.

Ugesi wesigaba esisodwa ubhekisela efomini lokuthuthwa kukagesi eliqukethe umugqa wesigaba kanye nomugqa ongu-zero. Umugqa wesigaba, owaziwa nangokuthi umugqa womlilo, uhlinzeka ngogesi ukuze ulayishwe, kanti umugqa ongathathi hlangothi usetshenziswa njengendlela yokubuyisela amandla kagesi. I-voltage kagesi wesigaba esisodwa ingama-volts angu-220, okuyi-voltage ephakathi komugqa wesigaba kuya kumugqa ongu-zero.

Emndenini nasehhovisi, ugesi wesigaba esisodwa uhlobo lwamandla oluvame kakhulu. Ngakolunye uhlangothi, ugesi wesigaba ezimbili uyisekethe yokunikezwa kwamandla eyakhiwe imigqa yesigaba ezimbili, ebizwa ngokuthi ugesi wesigaba ezimbili ngamafuphi. Kugesi wesigaba ezimbili, i-voltage phakathi komugqa wesigaba ibizwa ngokuthi i-voltage yocingo, ngokuvamile ingama-volts angu-380.

Ngokuphambene nalokho, i-voltage kagesi wesigaba esisodwa yi-voltage ephakathi komugqa wesigaba nomugqa ongu-zero, obizwa ngokuthi i-voltage yesigaba. Emishini yasekhaya yezimboni kanye neyasekhaya ethile, njengemishini yokushisela, womabili ugesi wesigaba usetshenziswa kabanzi.

Ngamafuphi, umehluko omkhulu phakathi kukagesi wesigaba esisodwa nowesigaba ezimbili uhlobo kanye ne-voltage yokudlulisa amandla kagesi. Ugesi wesigaba esisodwa uqukethe umugqa wesigaba kanye nomugqa ongu-zero, ofanele umndeni kanye nendawo yehhovisi ene-voltage engama-volts angu-220. Ukunikezwa kukagesi wesigaba ezimbili kuqukethe imigqa emibili yesigaba, efanelekile kumishini yasekhaya yezimboni kanye neyasekhaya ethile ene-voltage engama-volts angu-380.

Ukunikezwa kwamandla kagesi kwesigaba esisodwa: ngokuvamile kubhekisela kunoma yimuphi umugqa wesigaba (owaziwa kakhulu ngokuthi umugqa womlilo) kumandla e-AC esigaba sesithathu nemigqa emine engu-380V. I-voltage ingu-220V. Umugqa wesigaba ulinganiswa ngepeni kagesi evamile ene-voltage ephansi. Amandla avame kakhulu empilweni. Isigaba esisodwa yinoma yimuphi wemigqa yesigaba sesithathu eya kumugqa we-zero. Ngokuvamile ubizwa ngokuthi “umugqa womlilo” kanye “nomugqa we-zero”. Ngokuvamile kubhekisela kumandla e-AC angu-220V kanye no-50Hz. Isayensi yobunjiniyela kagesi yesigaba esisodwa ibizwa nangokuthi “i-voltage yesigaba”.
Ukunikezwa kwamandla ezigaba ezintathu: Ukunikezwa kwamandla okwakhiwa ngemvamisa efanayo yamaza amathathu kanye nama-amplitude alinganayo, kanye nesigaba se-AC potential esakhiwe ngama-degrees angu-120 e-engeli kagesi ngokujika sibizwa ngokuthi ukunikezwa kwamandla e-AC ezigaba ezintathu. Kukhiqizwa yijeneretha ye-AC yezigaba ezintathu. Amandla e-AC esigaba esisodwa asetshenziswa empilweni yansuku zonke anikezwa yisigaba samandla e-AC ezigaba ezintathu. Ukunikezwa kwamandla e-AC esigaba esisodwa okukhishwe yijeneretha yesigaba esisodwa akukaze kusetshenziswe.

Izintambo ezintathu ze-transformer kagesi zesigaba esisodwa
Umehluko phakathi kwamandla esigaba esisodwa kanye namandla esigaba sesithathu ukuthi ugesi ovela kujeneretha unezigaba ezintathu. Isigaba ngasinye sogesi wesigaba sesithathu singakha isekethe yesigaba esisodwa ukuze sinikeze abasebenzisi amandla kagesi. Kalula nje, kunemigqa yesigaba emithathu (imigqa yomlilo) kanye nomugqa ongu-zero (noma umugqa ophakathi), futhi ngezinye izikhathi kusetshenziswa imigqa yesigaba emithathu kuphela. I-voltage phakathi komugqa wesigaba kanye nomugqa wesigaba ingu-380 volt, kanti i-voltage phakathi kwemigqa yesigaba kanye nomugqa ongu-zero ingu-220 volts. Kukhona umugqa owodwa womlilo kanye nocingo olungu-zero, kanti i-voltage phakathi kwazo ingu-220 volts. Ugesi we-AC wesigaba sesithathu uyinhlanganisela yamandla e-AC yesigaba esisodwa anobukhulu obulinganayo, imvamisa elinganayo, kanye nomehluko wesigaba esingu-120 °. Ugesi wesigaba esisodwa uyinhlanganisela yanoma yimuphi umugqa wesigaba kanye nomugqa ongu-zero kugesi wesigaba sesithathu.

Isivikelo Sokuvuza Esihlakaniphile SaseNingizimu-Dou-Xing (Ugesi Ohlakaniphile)
Yiziphi izinzuzo zazo zombili? Amandla e-AC esigaba sesithathu anezinzuzo eziningi kunamandla e-AC esigaba esisodwa. Aphakeme ngokusobala maqondana nokukhiqizwa kwamandla, ukudluliselwa kanye nokusatshalaliswa, kanye nokuguqulwa kwamandla kagesi abe amandla omshini. Isibonelo: amajeneretha esigaba sesithathu kanye nama-transformer akhiqizwa kunejeneretha esigaba esisodwa anomthamo ofanayo kanye nezinto zokonga izinto, futhi alula ngesakhiwo kanye nokusebenza okuhle kakhulu. 50% wobukhulu. Endabeni yokuthutha amandla afanayo, izintambo zokudlulisa zesigaba sesithathu zingonga u-25% wezinsimbi ezingezona i-ferrous kunezintambo zokudlulisa zesigaba esisodwa, kanti ukulahlekelwa kwamandla kagesi kuncane kunokwe-transmission yesigaba esisodwa.
