Umahluko phakathi kombane wesigaba esinye, umbane wezigaba ezibini, kunye nombane wezigaba ezithathu

Umbane wesigaba esinye kunye nesigaba sesibini ziindlela ezimbini ezahlukeneyo zobonelelo lwamandla. Zinokwahlukana okuphawulekayo kwifom kunye ne-voltage yokuhanjiswa kombane.

Umbane wesigaba esisodwa ubhekisela kwifomu yokuthutha umbane equkethe umgca wesigaba kunye nomgca we-zero. Umgca wesigaba, owaziwa ngokuba ngumgca womlilo, unika umbane ukulayisha, kwaye umgca ongathathi hlangothi usetyenziswa njengendlela yokubuyisela okwangoku. I-voltage ye-single-phase yombane i-volts engama-220, eyi-voltage phakathi komgca wesigaba ukuya kumgca we-zero.

Kwimeko yosapho kunye neofisi, umbane wesigaba esinye lolona hlobo luxhaphakileyo lwamandla. Kwelinye icala, unikezelo lombane lwezigaba ezibini lubonelelo lombane lwesekethe oluqulunqwe ziintambo zesigaba ezibini, ekubhekiselwa kuzo njengombane wezigaba ezibini ngokufutshane. Kumbane wesigaba sesibini, i-voltage phakathi komgca wesigaba ibizwa ngokuba yi-wire voltage, ngokuqhelekileyo i-380 volts.

Ngokwahlukileyo, i-voltage yombane wombane wesigaba esisodwa yi-voltage phakathi komgca wesigaba kunye nomgca we-zero, obizwa ngokuba yi-voltage yesigaba. Kwimizi-mveliso kunye nezixhobo ezithile zendlu, ezinje ngoomatshini bokuwelda, zombini umbane wesigaba usetyenziswa kakhulu.

Isishwankathelo, umahluko omkhulu phakathi kwesigaba esisodwa kunye nesigaba sesibini sombane yifom kunye nombane wokuhambisa amandla ombane. Umbane wesigaba esisodwa uquka umgca wesigaba kunye nomgca we-zero, ofanelekileyo kwintsapho kunye ne-ofisi yendawo ene-voltage ye-220 volts. Unikezelo lwamandla amanqanaba amabini luquka imigca emibini yesigaba, efanelekileyo kwimizi-mveliso kunye nezixhobo ezithile zendlu kunye nombane we-380 volts.

Unikezelo lwamandla ombane wesigaba esinye: ngokuqhelekileyo lubhekisela kuwo nawuphi na umgca wesigaba (esaziwa ngokuba ngumgca womlilo) kwi-380V yesigaba sesithathu kunye ne-AC yamandla e-AC. Umbane ngu-220V. Umgca wesigaba ulinganiswa ngepeni yombane eqhelekileyo ephantsi-voltage. Awona mandla aqhelekileyo ebomini. Isigaba esinye siso nawuphi na umgca wesigaba esithathu ukuya kumgca onguziro. Idla ngokubizwa ngokuba "ngumgca womlilo" kunye "nomgca we-zero". Ngokubanzi ibhekisa kumandla e-220V kunye ne-50Hz AC. Inqanaba elinye lenzululwazi yobunjineli bombane ikwabizwa ngokuba “yisigaba sombane”.
Unikezelo lombane lwesigaba sesithathu: Unikezelo lwamandla olwenziwa ngokuphindaphindiweyo kwee-frequencies ezintathu kunye ne-amplitudes elinganayo, kunye nesigaba se-AC enokuthi iqulunqwe yi-degrees ze-120 ye-angle yombane ngokulandelelana ibizwa ngokuba yisigaba sesithathu sombane we-AC. Iveliswa yijenereyitha ye-AC enezigaba ezithathu. I-single-phase ye-AC amandla asetyenziswa kubomi bemihla ngemihla inikezelwa ngesigaba sesithathu se-AC amandla. Unikezelo lwamandla lwe-AC lwenqanaba elinye olukhutshwe yijenereyitha yesigaba esinye alufane lusetyenziswe.

I-3 yesigaba esisodwa sombane we-wiring ye-wiring yombane
Umahluko phakathi kombane wesigaba esinye kunye nesigaba sesithathu sombane kukuba unikezelo lwamandla oluvela kwijeneretha lukwinqanaba lesithathu. Isigaba ngasinye sonikezelo lombane lwezigaba ezithathu sinokwenza isekethe yesigaba esinye ukunika abasebenzisi amandla ombane. Ukubeka nje, kukho imigca yesigaba emithathu (imigca yomlilo) kunye nomgca we-zero (okanye umgca ophakathi), kwaye ngamanye amaxesha imigca yesigaba emithathu kuphela isetyenziswa. Umbane phakathi komgca wesigaba kunye nomgca wesigaba ngu-380 volt, kunye ne-voltage phakathi kwemigca yesigaba kunye nomgca we-zero yi-220 volts. Kukho umgca omnye womlilo kunye nocingo lwe-zero, kwaye i-voltage phakathi kwabo yi-220 volts. Isigaba sesithathu sombane we-AC yindibaniselwano yesigaba esisodwa se-AC amandla kunye ne-amplitude elinganayo, i-frequency elinganayo, kunye ne-120 ° umehluko wesigaba. Umbane wesigaba esinye yindibaniselwano yanoma yimuphi umgca wesigaba kunye nomgca we-zero kumbane wesigaba sesithathu.

Umkhuseli waseMzantsi-Dou-Xing-Smart-Leakage (uMbane oSmart)
Ziziphi iingenelo zabo bobabini? Amandla e-AC amanqanaba amathathu aneenzuzo ezininzi kunesigaba esinye se-AC samandla. Inokuphakama okucacileyo malunga nokuveliswa kwamandla, ukuhanjiswa kunye nokuhanjiswa, kunye nokuguqulwa kwamandla ombane kumandla oomatshini. Umzekelo: iijeneretha zesigaba sesithathu kunye neenguqu zenziwa ngaphezu kweejeneretha zesigaba esisodwa kunye nomthamo ofanayo kunye nezinto zokulondoloza izinto eziphathekayo, kwaye zilula kwisakhiwo kunye nokusebenza kakuhle kakhulu. I-50% yobungakanani. Kwimeko yothutho lwamandla afanayo, iingcingo zothumelo lwesigaba sesithathu zinokugcina i-25% yeentsimbi ezingezizo ezoni kuneengcingo zothumelo lwesigaba esinye, kwaye ilahleko yamandla ombane ingaphantsi kwaleyo yothumelo lwesigaba esinye.
