Isebenza kanjani isistimu yamandla ye-DC?

Amandla e-DC anama-electrode amabili, amahle nangalungile. Amandla e-electrode enhle aphezulu futhi amandla e-electrode engalungile aphansi. Lapho ama-electrode amabili exhunywe kwisekethe, umehluko oqhubekayo wamandla ungagcinwa phakathi kwezinhlangothi ezimbili zesekethe, ukuze kusekethe yangaphandle u-A ugeleze usuka kokuhle uye kokubi. Umehluko phakathi kwezinga lamanzi wodwa awukwazi ukugcina ukugeleza kwamanzi okuzinzile, kodwa ngosizo lwephampu lokuthumela amanzi ngokuqhubekayo kusuka endaweni ephansi kuya endaweni ephezulu, umehluko othile wamazinga amanzi ungagcinwa ukuze kwakheke ukugeleza kwamanzi okuzinzile.

Uhlelo lwe-DC lusetshenziswa ezitshalweni zamandla kagesi ezisebenzisa amanzi kanye nezokushisa kanye neziteshini ezincane ezahlukahlukene. Uhlelo lwe-DC lwakhiwe kakhulu ngamaphakethe ebhethri, amadivayisi okushaja, amaphaneli e-DC feeder, amakhabethe okusabalalisa e-DC, amadivayisi okuqapha amandla e-DC, kanye nama-feeder egatsha le-DC. Inethiwekhi enkulu nesatshalalisiwe yokunikezwa kwamandla kagesi e-DC inikeza amandla okusebenza aphephile futhi anokwethenjelwa amadivayisi okuvikela ama-relay, ukukhubeka nokuvala kwe-circuit breaker, izinhlelo zesignali, amashaja e-DC, ukuxhumana kwe-UPSc kanye nezinye izinhlelo ezincane.

Kunezimiso ezimbili zokusebenza, enye ukusebenzisa amandla amakhulu ukuguqula i-AC ibe yi-DC; enye isebenzisa i-DC

I-AC kuya ku-DC

Uma i-voltage enkulu iguqulwa ibe yi-voltage eklanyelwe nge-input switch bese i-transformer ivuliwe, ingena kwi-pre-stabilizing circuit. I-pre-stabilizing circuit iwukwenza ukulawulwa kwe-voltage yokuqala ku-voltage ephumayo oyifunayo, futhi inhloso yayo ukunciphisa ukulungiswa kwamandla aphezulu. Ukwehla kwe-voltage yeshubhu phakathi kokufakwayo nokukhishwa kweshubhu kunganciphisa ukusetshenziswa kwamandla kweshubhu elawula amandla aphezulu futhi kuthuthukise ukusebenza kahle kokunikezwa kwamandla e-DC. qinisa i-voltage. Ngemva kokudlula ekuhlinzekweni kwamandla okulawulwa kwangaphambili kanye nokuhlunga i-voltage etholakele izinzile ngokuyisisekelo futhi i-DC current ene-ripple encane idlula kwishubhu elawula amandla aphezulu elawulwa yi-control circuit ukuze ibuze ngokunembile nangokushesha ukucindezela okuphezulu, futhi ukunemba nokusebenza kokulawulwa kwe-voltage kuzohlangabezana nezindinganiso. Ngemva kokuthi i-DC voltage ihlungiwe yi-filter 2, kutholakala amandla e-DC okukhipha engiwadingayo. Ukuze sithole inani le-voltage yokukhipha noma inani lamanje elihlala njalo engiwadingayo, sidinga futhi ukusampula nokuthola inani le-voltage yokukhipha kanye nenani lamanje. Futhi uma idluliselwa kusekethe yokulawula/yokuvikela, isekethe yokulawula/yokuvikela iqhathanisa futhi ihlaziye inani le-voltage yokukhipha elitholiwe kanye nenani lamanje nenani elibekwe yisekethe yokusetha i-voltage/yamanje, bese ishayela isekethe yangaphambi kokulawula kanye neshubhu yokulungisa enamandla aphezulu. Ukunikezwa kwamandla okuzinzile kwe-DC kungakhipha amanani e-voltage kanye namanani wamanje esiwabekayo. Futhi ngesikhathi esifanayo, lapho isekethe yokulawula/yokuvikela ithola amanani e-voltage angajwayelekile noma amanani wamanje, isekethe yokuvikela izosebenza ukuze yenze ukunikezwa kwamandla kwe-DC kungene esimweni sokuvikela.

Ukunikezwa kwamandla e-DC

Imigqa emibili engenayo ye-AC ikhipha i-AC eyodwa (noma umugqa owodwa kuphela ongenayo we-AC) ngedivayisi yokushintsha ukuze inikeze amandla kumojuli ngayinye yokushaja. Imojuli yokushaja iguqula amandla e-AC efakayo ezigaba ezintathu abe amandla e-DC, ishaja ibhethri, futhi inikeze amandla kumthwalo webhasi elivalayo ngesikhathi esifanayo. Ibha yebhasi elivalayo inikeza amandla kubha yebhasi yokulawula ngedivayisi ehlayo (eminye imiklamo ayidingi idivayisi ehlayo)

Ukunikezwa kwamandla e-DC

Iyunithi ngayinye yokuqapha ohlelweni iphathwa futhi ilawulwa yiyunithi eyinhloko yokuqapha, futhi ulwazi oluqoqwe yiyunithi ngayinye yokuqapha luthunyelwa kuyunithi eyinhloko yokuqapha ukuze kuphathwe ngokuhlangene ngomugqa wokuxhumana we-RS485. I-monitor eyinhloko ingabonisa ulwazi oluhlukahlukene ohlelweni, futhi umsebenzisi angabuza ulwazi lwesistimu futhi aqaphele "umsebenzi omane okude esikrinini sokubonisa i-monitor eyinhloko ngokusebenzisa ukusebenza kokuthinta noma ukhiye. Ulwazi lwesistimu lungafinyelelwa futhi ngesibonisi sokuxhumana sekhompyutha esiphethe ku-monitor eyinhloko. Uhlelo lokuqapha olukude. Ngaphezu kweyunithi eyisisekelo yokulinganisa ephelele, uhlelo lungafakelwa namayunithi asebenzayo njengokuqapha kokushisa, ukuhlolwa kwebhethri, kanye nokuqapha inani lokushintsha, asetshenziselwa ukuqapha ngokuphelele uhlelo lwe-DC.
