Amandla e-DCinama-electrode amabili, i-positive ne-negative.Amandla we-electrode enhle aphakeme futhi amandla e-electrode engalungile aphansi.Lapho ama-electrode amabili exhunywe kumjikelezo, umehluko ongase ube khona njalo ungagcinwa phakathi kweziphetho ezimbili zesekethe, ukuze kumjikelezo wangaphandle A ugeleza kusukela kokuhle kuya kokubi.Umehluko phakathi kwezinga lamanzi wodwa awukwazi ukugcina ukugeleza kwamanzi okuzinzile, kodwa ngosizo lwepompo ukuze uqhubeke nokuthumela amanzi ukusuka endaweni ephansi ukuya endaweni ephakeme, umehluko othile wamanzi ungagcinwa ukuze wenze ukugeleza kwamanzi okuqhubekayo.
IIsistimu ye-DCisetshenziswa ezitshalweni zamandla kagesi kanye ne-thermal kanye neziteshi ezingaphansi ezihlukahlukene.Uhlelo lwe-DC ikakhulukazi lwakhiwe amaphakethe ebhethri, izisetshenziswa zokushaja, amaphaneli e-DC feeder, amakhabethe okusabalalisa e-DC, amadivaysi okuqapha amandla e-DC, kanye neziphakeli zegatsha le-DC.Inethiwekhi enkulu futhi esabalalisiwe yokuphakelwa kwamandla kagesi e-DC inikeza amandla okusebenza aphephile nathembekile emishini yokuvikela ukudluliselwa, ukugingqika nokuvala i-circuit breaker, amasistimu wamasignali, amashaja e-DC, i-UPS, ezokuxhumana kanye nezinye izinhlelo ezingaphansi.
Kunezimiso ezimbili zokusebenza, eyodwa ukusebenzisa amandla amakhulu ukuguqula i-AC ibe yi-DC;enye isebenzisa i-DC.
AC kuya ku-DC
Lapho i-voltage yamapayipi iguqulwa ibe yi-voltage eklanyelwe ngokusebenzisa inkinobho yokufaka futhi i-transformer ivuliwe, ingena kumjikelezo wangaphambi kokuzinza.Isifunda sokuzinzisa ngaphambili siwukwenza umthetho wokuqala we-voltage ku-voltage oyifunayo, futhi inhloso yawo ukunciphisa ukulungiswa kwamandla aphezulu.Ukwehla kwamandla kagesi weshubhu phakathi kokokufaka nokuphumayo kweshubhu kunganciphisa ukusetshenziswa kwamandla kweshubhu elilawulayo lamandla aphezulu futhi kuthuthukise ukusebenza kahle kokuphakelwa kukagesi kwe-DC.uzinzise i-voltage.Ngemva kokudlula kugesi nesihlungi esilawulwa ngaphambili ①, i-voltage etholiwe iyazinza ngokuyisisekelo futhi i-DC yamanje ene-ripple encane idluliswa ngeshubhu elilawulayo lamandla aphezulu elilawulwa yisekhethi yokulawula ukuze ibuze ngokunembile nangokushesha ingcindezi ephezulu, kanye nokunemba kokulawulwa kwamandla kagesi nokusebenza kuzohlangabezana nezinga.Ngemuva kokuthi i-voltage ye-DC ihlungwe yisihlungi ②, amandla e-DC aphumayo engiwadingayo ayatholakala.Ukuze sithole inani le-voltage ephumayo noma inani lamanje elingashintshi engilidingayo, sidinga futhi ukuthatha isampula futhi sithole inani le-voltage ephumayo kanye nevelu yamanje.Futhi uyidlulisele kusekethe yokulawula/yokuvikela, isekethe yokulawula/yokuvikela iqhathanisa futhi ihlaziye inani elitholiwe le-voltage ephumayo kanye nenani lamanje nenani elibekwe yisekethe yokusetha kagesi/yamanje, futhi ishayela isekethe yesilawuli sangaphambili namandla aphezulu. ithubhu yokulungisa.Ukunikezwa kwamandla okuzinzile kwe-DC kungakhipha i-voltage kanye namanani amanje esiwabekayo, futhi ngasikhathi sinye, lapho isekethe yokulawula/yokuvikela ithola amanani angalungile kagesi noma amanani amanje, umjikelezo wokuvikela uzovulwa ukuze wenze ugesi we-DC ungene isimo sokuvikela.
Ukunikezwa kwamandla kwe-DC
Imigqa emibili ye-AC engenayo ikhipha i-AC eyodwa (noma ulayini owodwa we-AC owodwa kuphela) ngokusebenzisa idivayisi yokushintsha ukuze inikeze amandla kumojula ngayinye yokushaja.Imojula yokushaja iguqula amandla e-AC ezigaba ezintathu abe amandla e-DC, ishaje ibhethri, futhi inikeze amandla kumthwalo webhasi elivalayo ngesikhathi esifanayo.Ibha yebhasi evalayo inika amandla kubha yokulawula ngedivayisi yokuya phansi (eminye imiklamo ayidingi idivayisi yokuya phansi).

Ukunikezwa kwamandla kwe-DC
Iyunithi ngayinye yokuqapha ohlelweni ilawulwa futhi ilawulwa yiyunithi yokuqapha eyinhloko, futhi ulwazi oluqoqwe yiyunithi yokuqapha ngayinye luthunyelwa ophikweni oluyinhloko lokuqapha ukuze kuphathwe ngobunye ngolayini wokuxhumana we-RS485.Imonitha eyinhloko ingabonisa ulwazi oluhlukahlukene ohlelweni, futhi umsebenzisi angaphinda abuze ulwazi lwesistimu futhi abone umsebenzi "okude okune" esikrinini sokubonisa imonitha enkulu ngokuthinta noma ukusebenza kokhiye.Ulwazi lwesistimu lungabuye lufinyelelwe ngokusebenzisa isikhombimsebenzisi sokuxhumana sekhompiyutha esiqashweni esikhulu.Isistimu yokuqapha ekude.Ngokungeziwe kuyunithi eyisisekelo yokulinganisa ebanzi, isistimu ingaphinda ifakwe amayunithi asebenzayo afana nokugadwa kokufakwa ngaphakathi, ukuhlolwa kwebhethri, nokuqapha inani lokushintsha, okusetshenziselwa ukuqapha ngokugcwele uhlelo lwe-DC.
