Mumagetsi, chikamu chinoreva kugoverwa kwemutoro. Ndeupi musiyano uripo pakati pechikamu chimwe chete uye matatu-chikamu magetsi emagetsi? Musiyano uripo pakati pezvikamu zvitatu nechikamu chimwe chete unonyanya kuve mumhepo inogamuchirwa kuburikidza nemhando yega yega yewaya. Iko hakuna chinhu chakadai sesimba rezvikamu zviviri, izvo zvinoshamisa kune vamwe vanhu. Single-phase simba rinowanzonzi 'split-phase'.
Dzimba dzekugara dzinowanzo kushandirwa nechikamu chimwe chete chemagetsi, nepo nzvimbo dzekutengesa uye dzemaindasitiri dzinowanzoshandisa chikamu chetatu-chikamu. Imwe mutsauko wakakosha pakati pechikamu chimwe nenhatu-chikamu ndechekuti matatu-chikamu magetsi ekupa zvirinani anogara yakakwira mitoro. Single-phase magetsi emagetsi anonyanya kushandiswa kana akajairwa mitoro iri kuvheneka kana kupisa, pane mahombe emagetsi mota.
Single Phase
Single-phase wire ine tambo nhatu dziri mukati me insulation. Waya mbiri dzinopisa uye imwe isina kwayakarerekera waya inopa simba. Waya imwe neimwe inopisa inopa 120 volts emagetsi. Iyo isina kwayakarerekera inobviswa kubva kune transformer. Dunhu rezvikamu zviviri rinogona kunge riripo nekuti maheater emvura mazhinji, zvitofu uye zvekuomesa mbatya zvinoda 240 volts kuti ishande. Aya maseketi anodyiswa newaya ari maviri anopisa, asi iyi ingori yakazara chikamu chedunhu kubva kune imwe-chikamu waya. Chese chimwe chigadziro chinoshandiswa kubva pa120 volts yemagetsi, iyo iri kungoshandisa waya imwe inopisa uye isina kwayakarerekera. Rudzi rwedunhu rinoshandisa waya dzinopisa uye dzisina kwazvakarerekera ndosaka ichiwanzonzi kupatsanurwa-chikamu chedunhu. Iyo single-phase waya ine waya mbiri dzinopisa dzakakomberedzwa neblack uye tsvuku insulation, iyo isina kwayakarerekera inogara yakachena uye kune yakasvibira pasi waya.
Three Phase
Simba rechitatu-chikamu rinopihwa netambo ina. Waya nhatu dzinopisa dzakatakura 120 volts emagetsi uye imwe isina kwayakarerekera. Waya mbiri dzinopisa uye isina kwayakarerekera inomhanya kune chidimbu chemuchina chinoda 240 volts emagetsi. Simba rechitatu-chikamu rinonyanya kushanda kupfuura simba rimwechete-chikamu. Fungidzira mumwe murume achisunda motokari achikwidza chikomo; uyu muenzaniso wesimba rechikamu chimwe chete. Simba rezvikamu zvitatu rakafanana nekuva nevarume vatatu vane simba rakaenzana vachisunda motokari imwe chete iyoyo kukwira gomo rimwe chete. Iwo matatu mawaya anopisa muchikamu chetatu-chikamu ane mavara madema, bhuruu uye tsvuku; waya chena ndiyo isina kwayakarerekera uye waya yegirini inoshandiswa kuvhu.
Imwe misiyano pakati pematatu-phase waya uye imwe-phase waya inonetsekana apo imwe neimwe mhando yewaya inoshandiswa. Zvizhinji, kana zvisiri zvese, dzimba dzekugara dzine single-phase wire yakaiswa. Zvivakwa zvese zvekutengesa zvine matatu-phase waya yakaiswa kubva kukambani yemagetsi. Matatu-chikamu mota dzinopa simba rakawanda kupfuura imwe-chikamu mota inogona kupa. Sezvo nzvimbo zhinji dzekutengesa dzichishandisa michina nemidziyo inomhanya-nhatu-chikamu mota, matatu-chikamu waya inofanira kushandiswa kushandisa masisitimu. Zvese zviri mumusha wekugara zvinongoshanda zvichibva pamagetsi echikamu chimwe chete senge zvitoro, mwenje, firiji uye kunyange midziyo inoshandisa 240 volts yemagetsi.
