Musiyano pakati pemagetsi ega-chikamu, magetsi maviri-chikamu, uye matatu-chikamu magetsi

Single-phase uye maviri-phase magetsi inzira mbiri dzakasiyana dzekupa magetsi. Vane misiyano yakakura muchimiro uye voltage yekufambisa kwemagetsi.

Single -phase magetsi inoreva fomu yekufambisa yemagetsi ine mutsara wechikamu uye zero mutsara. Mutsara wechikamu, unozivikanwawo semutsara wemoto, unopa magetsi kurodha, uye mutsara usina kwawakarerekera unoshandiswa senzira yekudzoka ikozvino. Mhepo yemagetsi ega-phase magetsi ndeye 220 volts, iyo ndiyo voltage pakati pemutsara wechikamu kusvika kune zero line.

Mumhuri uye muhofisi nharaunda, single-phase magetsi ndiyo yakajairika simba mhando. Kune rumwe rutivi, maviri-chikamu magetsi emagetsi emagetsi emagetsi anoumbwa nemitsara miviri yechikamu, inonzi maviri-phase magetsi kwenguva pfupi. Mumagetsi maviri-chikamu, mhepo iri pakati pemutsara wechikamu inonzi wire voltage, kazhinji 380 volts.

Kusiyana neizvi, magetsi emagetsi emagetsi emagetsi emagetsi emagetsi ari pakati pemutsara wechikamu uye zero line, iyo inonzi phase voltage. Mumaindasitiri uye chaiwo midziyo yemumba, yakadai semichina yewelding, ese magetsi echikamu anoshandiswa zvakanyanya.

Muchidimbu, musiyano mukuru pakati pe-single-phase uye maviri-phase magetsi ndiyo fomu uye voltage yemagetsi ekufambisa simba. Single-phase magetsi ine mutsara wechikamu uye zero mutsara, iyo inokodzera mhuri uye hofisi nharaunda ine voltage ye220 volts. Iwo maviri-chikamu magetsi emagetsi ane maviri echikamu mitsara, akakodzera maindasitiri uye chaiwo midziyo yemumba ine voltage ye380 volts.

Single -phase power supply: kazhinji inoreva chero mutsara wechikamu (unowanzozivikanwa semutsara wemoto) mu 380V katatu -phase uye ina -line AC simba. Iyo voltage ndeye 220V. Mutsetse wechikamu unopimwa nepeni yemagetsi yakaderera-voltage. Simba rinonyanyozivikanwa muhupenyu. Single-phase ndiyo imwe yemitsara yezvikamu zvitatu kusvika kumutsara we zero. Inowanzonzi "fire line" uye "zero line". Kazhinji zvinoreva 220V uye 50Hz AC simba. Iyo imwe-phase yemagetsi engineering sainzi inonzi zvakare "phase voltage".
Three-phase magetsi ekupa: Iyo magetsi inoumbwa neiyo yakafanana frequency yeatatu mafrequencies uye akaenzana amplitudes, uye chikamu cheiyo AC inogoneka inoumbwa ne120 madhigirii emagetsi angle inozodaidzwa kuti matatu-phase AC magetsi. Iyo inogadzirwa neatatu-chikamu AC jenareta. Iyo imwechete -phase AC simba rinoshandiswa muhupenyu hwezuva nezuva rinopihwa nechikamu chetatu -phase AC simba. Iyo imwechete -phase AC magetsi ekupa yakapihwa neamwechete -phase jenareta haisati yashandiswa.

Musiyano pakati pe-single-phase simba uye matatu-phase simba rekupa nderokuti magetsi kubva kune jenareta ari matatu-chikamu. Chikamu chega chega chetatu-phase simba rekupa chinogona kuumba imwe-chikamu chedunhu kupa vashandisi simba remagetsi. Zvichitaurwa zviri nyore, kune mitsara yezvikamu zvitatu (mitsetse yemoto) uye zero mutsara (kana yepakati-mutsara), uye dzimwe nguva mitsetse mitatu yechikamu ndiyo inoshandiswa. Mhepo iri pakati pemutsara wechikamu uye mutsara wechikamu ndeye 380 volt, uye voltage pakati pemitsara yechikamu uye zero mutsara ndeye 220 volts. Pane mutsara mumwe chete wemoto uye zero waya, uye voltage pakati pavo ndeye 220 volts. Three -phase AC magetsi musanganiswa we single -phase AC simba ine yakaenzana amplitude, yakaenzana frequency, uye 120 ° phase musiyano. Single-phase magetsi inobatanidza chero mutsara wechikamu uye zero mutsetse wemagetsi matatu.

Ndezvipi zvakanakira vaviri vacho? Three-phase AC simba rine akawanda mabhenefiti pane single-phase AC simba. Iine hukuru huri pachena maererano nekugadzirwa kwemagetsi, kutumira uye kugovera, uye simba remagetsi rekushandura kuita mechanical simba. Semuenzaniso: matatu-phase generator uye transformers inogadzirwa kupfuura imwe -phase generator ine simba rakafanana uye zvinhu zvekuchengetedza zvinhu, uye zviri nyore mukugadzirisa uye kushanda kwakanakisisa. 50% yehukuru. Panyaya yekutakura simba rimwe chete, iyo mitatu-phase transmission wires inogona kuchengetedza 25% ye-non-ferrous metals pane imwe-phase transmission wires, uye kurasikirwa kwemagetsi kuduku kudarika kwe-single-phase transmission.
