Iimitha zombane ngoku zifakwe kuzo zonke izindlu, iofisi okanye isakhiwo solawulo. Kodwa ngamanye amaxesha, xa kuziwa ekutshintsheni i-counter elidala ukuya kwelinye elithile, siya kwisitoreji kwaye silahlekelwe ngobuninzi bemifanekiso, singayazi into enokuyikhetha.
Kule nqaku uza kufunda malunga nokuba i - counter -phase counter ikuphi kumitha yesigaba esithathu , kwaye ungakhetha njani le ndlela ifowuni efanelwe nawe.
Ziziphi izinto zokubala ezikhoyo?
Ngoko ke, nayiphina imitha yombane yombane iyadingeka ukwenzela ukulinganisa umlinganiselo wombane ogqityiweyo ngexesha elithile. Into yolu mlinganiselo ngu-AC.
Iinqununu, njengoko uyazi, ziyodwa kunye neyintathu-isahluko sazo. Eyokuqala isetyenziselwa kakhulu izindlu nezindlu zangasese, amagaraji, ii-cottages, indawo yeofisi. Ziyakulungelelanisa amanethiwekhi ombane kunye nombane osebenzayo we-220 V kunye namaxesha angama-50 Hz. Kodwa iimitha zemizila emithathu zifakwe apho umbane wamandla ngu-380 V: umzekelo, kwizityalo ezinkulu zoshishino. Kodwa kufuneka uqaphele ukuba ezi zixhobo ziyakwazi ukuxhasa i-accounting-phase-phase, oko kukuthi isetyenziswe kwintanethi kunye nombane we-220 kunye no-380 V. Oku kulungele ukuba abanikazi bezindlu ezinkulu ngezixhobo ezinamandla ezifakwe apho (iibilisi zombane, ii- heaters , njl). Ngenjongo ke indlu indlu yesithathu imitha iyilwe.
Ukongezelela, ezi zixhobo ziyakwazi ukukhupha okanye i-elektroniki. Izixhobo ezisebenzisa umgaqo wokufakelwa kwe-electromagnetic ziqhelekileyo. Baxhotyiswe ngediski ejikelezayo, ngokungafani nebalawuli zekhompyutha, apho into enjalo ibonakaliso olukhanyayo.
Kwaye, ekugqibeleni, ii-counters zinye-kunye nemirhumo emininzi. Eyathandwa kakhulu namhlanje, enjalo imodeli njengesiqendu sesithathu semilinganiselo. Nangona kunjalo, ukufaneleka kokuthengwa kwayo kunye nokufakela kufuneka kubalwe ngabanye, kuba kungekhona yonke imimandla eyahlula iinkqubo zerhafu.
Imitha yesithathu yamandla kagesi - iimpawu zokukhetha
Ngaphambi kokuthenga i-counter, funda ulwazi olulandelayo olungakwenza ukhetho olufanelekileyo:
- Ukufumana ukuba yeyiphi na ifowuni oyifunayo, jonga kwi-scoreboard ye-counter yakho. Ukuba kukho isibalo se-220, ngoko yonke into iyilula - uthenge ngokukhuselekileyo imitha yesigaba esisodwa. Ukuba kukho umfanekiso we-220/380, kuya kufuneka uthenge imodeli yesigaba esithathu.
- Ukusebenzisa umbane wamagumbi kwigumbi apho izinga lokushisa lomoya lingaphantsi kwe-0 ° C, khetha imodeli eneepaspoti ezibonisa imida yokushisa efanelekileyo. Iimitha eziqhelekileyo zasemakhaya, njengomthetho, aziklanyelwe ukutshisa amaqondo okushisa.
- Xa uthengisa itekisi kwisitoreji, qiniseka ukuba ukhangele ubukho beempawu. Ukuba isitywina sinye sifakwe kwiimodeli zekhompyutheni, kufuneka kubekho ubuncinci amabinzana amabini okukhupha. Ngethuba elifanayo, ubuncinane omnye wabo ngumqondiso we-boss, ngelixa isibini ingaba yimpembelelo ye-OEM yomenzi. Iimpawu zokuzibophelela zinyuka kwiindawo zokukhawuleza kwaye zingenziwa zangaphandle (ezenziwe ngekhokelo okanye iplastiki) okanye zangaphakathi (zizaliswe kwisigxina esinomsolo omnyama okanye obomvu).
Izicwina mazibe zibhalwe ngokucacileyo kwaye zikhululeke kunoma yimuphi umonakalo owenziweyo. - Elinye iphuzu elibalulekileyo xa kuthengwa imitha emithathu yesigaba yithuba apho kuya kufuneka linikezelwe kwi-gospodarka elandelayo. Kwiimodeli ezindala zokuqhotyoshelweyo, oku kudla iminyaka engama-6 ukuya kwe-8, kunye nemodeli ye-elektroniki entsha ukuya kwiminyaka eyi-16. Nceda uqaphele ukuba ukuba ixesha lokumisela elichazwe kwipaspoti yeemitha liphantsi kakhulu, oku kungabonakalisa umgangatho ongafaneleki wefowuni oyithengayo.
- Futhi ungakulibali ukuba ngaphambi kokufaka endaweni yamitha emdala, kunye emva kokufaka enye entsha, kuyimfuneko ukumema oyingcali evela kwintlangano yokuthengiswa kombane wendawo eya kutywina imitha yakho yesigaba esithathu.
