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

Ugesi wesigaba esisodwa nesezigaba ezimbili yizindlela ezimbili ezihlukene zokuphakela ugesi. Zinomehluko omkhulu efomini kanye ne-voltage yokudluliselwa kukagesi.

Ugesi wesigaba esisodwa ubhekisela efomini lokuthutha likagesi elihlanganisa umugqa wesigaba kanye nolayini onguziro. Ulayini wesigaba, owaziwa nangokuthi ulayini womlilo, uhlinzeka ngogesi ukuze ulayishe, futhi umugqa ongathathi hlangothi usetshenziswa njengendlela yokubuyisela okwamanje. Amandla kagesi wesigaba esisodwa angama-volts angu-220, okuyi-voltage phakathi komugqa wesigaba kuya kulayini we-zero.

Emndenini nasehhovisi, ugesi wesigaba esisodwa uwuhlobo lwamandla oluvame kakhulu. Ngakolunye uhlangothi, ugesi wezigaba ezimbili uwumjikelezo wokuphakelwa kukagesi ohlanganiswe imigqa yezigaba ezimbili, okubizwa ngokuthi ugesi wezigaba ezimbili ngamafuphi. Kugesi wezigaba ezimbili, i-voltage phakathi komugqa wesigaba ibizwa ngokuthi i-voltage yocingo, ngokuvamile i-380 volts.

Ngokuphambene, i-voltage yesigaba esisodwa sikagesi kagesi yi-voltage phakathi komugqa wesigaba kanye nomugqa onguziro, obizwa ngokuthi i-voltage yesigaba. Emishinini yasendlini yezimboni nethize, njengemishini yokushisela, ugesi wesigaba womabili usetshenziswa kakhulu.

Kafushane, umehluko omkhulu phakathi kukagesi wesigaba esisodwa kanye nesigaba sesibili yindlela kanye ne-voltage yokudlulisa amandla kagesi. Ugesi wesigaba esisodwa uqukethe umugqa wesigaba kanye nomugqa we-zero, ofanele indawo yomndeni kanye nehhovisi nge-voltage ye-220 volts. Ugesi wezigaba ezimbili uqukethe imigqa yezigaba ezimbili, ezifanele izinto zikagesi zasezimbonini nezithize zasendlini ezinamandla kagesi angu-380 volts.

Ukunikezwa kwamandla kwesigaba esisodwa: ngokuvamile kubhekisela kunoma yimuphi ulayini wesigaba (owaziwa ngokuvamile ngokuthi ulayini womlilo) ku-380V amandla esigaba sesithathu kanye nemigqa emine ye-AC. I-voltage ingu-220V. Umugqa wesigaba ulinganiswa ngepeni likagesi eliphansi eliphansi. Amandla ajwayelekile kakhulu empilweni. Isigaba esisodwa yinoma yimuphi wemigqa yezigaba ezintathu kuya kumugqa onguziro. Kuvame ukubizwa ngokuthi "umugqa womlilo" kanye "nomugqa we-zero". Ngokujwayelekile isho amandla angu-220V kanye nama-50Hz AC. Isayensi yesigaba esisodwa sobunjiniyela kagesi nayo ibizwa ngokuthi "isigaba samandla".
Ukunikezwa kwamandla kwezigaba ezintathu: Ukunikezwa kwamandla okuhlanganiswe imvamisa efanayo yamafrikhwensi amathathu nama-amplitudes alinganayo, futhi isigaba samandla e-AC sakhiwe amadigri angu-120 we-engeli kagesi ngokushintshana sibizwa ngokuthi izigaba ezintathu ze-AC power supply. Ikhiqizwa ijeneretha ye-AC enezigaba ezintathu. Amandla esigaba esisodwa se-AC asetshenziswa empilweni yansuku zonke ahlinzekwa yisigaba samandla we-AC wezigaba ezintathu. Ukunikezwa kwamandla kwesigaba esisodwa se-AC okukhishwe ijeneretha yesigaba esisodwa akuvamile ukusetshenziswa.

Izintambo ezi-3 ze-single-phase kagesi eziguquguqukayo
Umehluko phakathi kwamandla esigaba esisodwa kanye nesigaba sesithathu samandla ukuthi amandla avela kujeneretha anezigaba ezintathu. Isigaba ngasinye sokunikezwa kwamandla kwezigaba ezintathu singakha isekethe yesigaba esisodwa ukunikeza abasebenzisi amandla kagesi. Kalula nje, kunemigqa yezigaba ezintathu (imigqa yomlilo) kanye nomugqa onguziro (noma umugqa ophakathi), futhi ngezinye izikhathi kusetshenziswa imigqa yezigaba ezintathu kuphela. I-voltage phakathi komugqa wesigaba kanye nomugqa wesigaba yi-380 volt, kanti i-voltage phakathi kwemigqa yesigaba nomugqa we-zero ingu-220 volts. Kukhona umugqa owodwa kuphela womlilo kanye nocingo lwe-zero, futhi i-voltage phakathi kwabo ingama-volts angu-220. Ugesi we-AC wezigaba ezintathu uyinhlanganisela yesigaba esisodwa samandla e-AC ane-amplitude elinganayo, imvamisa elinganayo, kanye nomehluko wesigaba esingu-120 °. Ugesi wesigaba esisodwa uyinhlanganisela yanoma yimuphi ulayini wesigaba nolayini onguziro kugesi wezigaba ezintathu.

Yiziphi izinzuzo zabo bobabili? Amandla e-AC ezigaba ezintathu anezinzuzo eziningi kunamandla esigaba esisodwa se-AC. Inokuphakama okusobala mayelana nokukhiqizwa kwamandla, ukudluliswa nokusabalalisa, kanye nokuguqulwa kwamandla kagesi abe amandla emishini. Isibonelo: ama-generator ezigaba ezintathu kanye nama-transformer akhiqizwa kunama-generator esigaba esisodwa esinamandla afanayo kanye nezinto zokulondoloza izinto ezibonakalayo, futhi zilula ngesakhiwo nokusebenza okuhle kakhulu. 50% kasayizi. Endabeni yokuthutha amandla afanayo, izintambo zokudlulisa zezigaba ezintathu zingonga u-25% wezinsimbi ezingezona ayoni kunezintambo zokudlulisa zesigaba esisodwa, futhi ukulahlekelwa kwamandla kagesi kungaphansi kwalokho okudluliswa kwesigaba esisodwa.
