Lusebenza kanjani uhlelo lwamandla e-DC?

Amandla e-DC anama-electrode amabili, e-positive kanye 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.

Uhlelo lwe-DC lusetshenziswa 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 ihlinzeka ngamandla okusebenza aphephile nathembekile kumadivayisi okuvikela ukudluliselwa, ukugingqika nokuvala ama-circuit breaker, amasistimu wamasignali, amashaja e-DC, ezokuxhumana nge-UPSc 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. Umjikelezo wokuzinza kwangaphambili uwukwenza 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. Ngemuva kokudlula kugesi olawulwa ngaphambilini nokuhlunga i-voltage etholiwe izinzile ngokuyisisekelo futhi i-DC yamanje ene-ripple encane idluliswa ngeshubhu elilawulayo lamandla aphezulu elilawulwa yisekethe yokulawula ukuze ibuze ngokunembile futhi ngokushesha ingcindezi ephezulu, futhi ukunemba kokulawulwa kwamandla kagesi nokusebenza kuzohlangabezana nezinga. Ngemuva kokuthi i-voltage ye-DC isihlungiwe yisihlungi 2, amandla e-DC okukhiphayo engiwadingayo ayatholakala. Ukuze sithole inani le-voltage ephumayo noma inani lamanje elingaguquki engilidingayo, sidinga futhi ukuthatha isampula futhi sithole ukuhlolwa kwe-voltag ephumayo kanye nenani lamanje. 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 ngesikhathi esifanayo, lapho isekethe yokulawula/yokuvikela ithola ama-voltage angavamile noma amanani amanje, isekethe yokuvikela izovulwa ukuze kwenziwe ugesi we-DC ungene esimweni 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 yebhasi yokulawula ngokusebenzisa idivayisi yokuya phansi (eminye imiklamo ayidingi idivayisi yokwehlisa)

Ukunikezwa kwamandla kwe-DC

Iyunithi ngayinye yokuqapha ohlelweni ilawulwa futhi ilawulwa yiyunithi yokuqapha eyinhloko, futhi ulwazi oluqoqwe yiyunithi ngayinye yokuqapha ithunyelwa 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 wokude okune kusikrini sokubonisa imonitha enkulu ngokuthinta noma ukusebenza kokhiye. Ulwazi lwesistimu lungabuye lufinyeleleke ngokusebenzisa isikhombimsebenzisi sokuxhumana sekhompiyutha emshinini omkhulu wokuqapha.Isistimu yokuqapha ekude. Ngaphezu kweyunithi eyisisekelo yokulinganisa ebanzi, isistimu ingabuye ifakwe amayunithi asebenzayo afana nokuqapha ukufakwa ngaphakathi, ukuhlolwa kwebhethri. kanye nokuqapha inani lokushintsha, okusetshenziselwa ukuqapha ngokugcwele uhlelo lwe-DC.
