Isebenza njani inkqubo yamandla yeDC?

Amandla e-DC anee-electrode ezimbini, ezilungileyo nezingalunganga. Amandla e-electrode entle aphezulu kwaye amandla e-electrode engalunganga aphantsi. Xa ezi electrode zimbini ziqhagamshelwe kwisekethe, umahluko ongapheliyo we-potential unokugcinwa phakathi kweziphelo ezimbini zesekethe, ukuze kwisekethe yangaphandle i-A current ihambe ukusuka kwi-positive ukuya kwi-negative. Umahluko phakathi kwenqanaba lamanzi lodwa awunakugcina ukuhamba kwamanzi okuzinzileyo, kodwa ngoncedo lwepompo yokuthumela amanzi ukusuka kwindawo ephantsi ukuya kwindawo ephezulu, umahluko othile wenqanaba lamanzi unokugcinwa ukwenza ukuhamba kwamanzi okuzinzileyo.

Inkqubo ye-DC isetyenziswa kwizityalo zamandla e-hydraulic kunye ne-thermal kunye nezikhululo ezahlukeneyo. Inkqubo ye-DC yenziwe ikakhulu zii-battery packs, izixhobo zokutshaja, iiphaneli ze-DC feeder, iikhabhathi zokusasaza ze-DC, izixhobo zokujonga umbane ze-DC, kunye nee-DC branch feeders. Inethiwekhi enkulu nesasazwe yombane ye-DC ibonelela ngamandla okusebenza akhuselekileyo nathembekileyo kwizixhobo zokukhusela i-relay, i-circuit breaker tripping kunye ne-closing, iinkqubo zesignali, iitshaja ze-DC, ii-UPSc comunications kunye nezinye iinkqubo ezingaphantsi.

Kukho imigaqo emibini yokusebenza, enye kukusebenzisa amandla ombane ukuguqula i-AC ibe yi-DC; enye isebenzisa i-DC

I-AC ukuya kwi-DC

Xa i-voltage ephambili iguqulwa ibe yi-voltage eyilwe ngeswitshi yokufaka kwaye i-transformer ivuliwe, ingena kwisekethe yokuzinzisa kwangaphambili. Isekethe yokuzinzisa kwangaphambili kukwenza ummiselo we-voltage yokuqala kwi-voltage yokuphuma oyifunayo, kwaye injongo yayo kukunciphisa uhlengahlengiso lwamandla aphezulu. Ukuwa kwe-voltage yetyhubhu phakathi kokungeniswa kunye nokuphuma kwetyhubhu kunokunciphisa ukusetyenziswa kwamandla kwetyhubhu elawula amandla aphezulu kunye nokuphucula ukusebenza kakuhle kombane we-DC. ukuzinzisa i-voltage. Emva kokudlula kumbane olawulwa kwangaphambili kunye nesihluzo, i-voltage efunyenweyo izinzile ngokusisiseko kwaye i-DC current ene-ripple encinci idlula kwityhubhu elawula amandla aphezulu elawulwa yisekethe yokulawula ukuze ibuze ngokuchanekileyo nangokukhawuleza uxinzelelo oluphezulu, kwaye ukuchaneka komgaqo we-voltage kunye nokusebenza kuya kuhlangabezana nomgangatho. Emva kokuba i-voltage ye-DC ihluziwe yi-filter 2, amandla e-DC ephumayo endiwadingayo ayafunyanwa. Ukuze sifumane ixabiso le-voltage yokuphuma okanye ixabiso langoku elihlala lihleli endilifunayo, kufuneka sithathe isampuli kwaye sibone ixabiso le-voltage yokuphuma kunye nexabiso langoku. Kwaye idlulisele kwisekethe yokulawula/yokukhusela, isekethe yokulawula/yokukhusela ithelekisa kwaye ihlalutye ixabiso le-voltage yokuphuma efunyenweyo kunye nexabiso langoku kunye nexabiso elibekwe yisekethe yokuseta i-voltage/yangoku, kwaye iqhuba isekethe yangaphambi kokulawula kunye netyhubhu yokulungisa amandla aphezulu. Umbane ozinzileyo we-DC unokukhupha ixabiso le-voltage kunye nexabiso langoku esilibekayo. kwaye kwangaxeshanye, xa isekethe yokulawula/yokukhusela ifumanisa i-voltage engaqhelekanga okanye ixabiso langoku, isekethe yokukhusela iya kusebenza ukuze yenze umbane we-DC ungene kwimeko yokukhusela.

Umbane weDC

Imigca emibini engenayo ye-AC ikhupha i-AC enye (okanye umgca omnye kuphela ongenayo we-AC) ngesixhobo sokutshintsha ukuze inike amandla kwimodyuli nganye yokutshaja. Imodyuli yokutshaja iguqula amandla e-AC angena kwisigaba sesithathu abe ngamandla e-DC, itshaja ibhetri, kwaye inike amandla kumthwalo webhasi yokuvala ngaxeshanye. Ibha yebhasi yokuvala inika amandla kwibha yebhasi yokulawula ngesixhobo sokwehla (ezinye iindlela zoyilo azidingi sixhobo sokwehla)

Umbane weDC

Iyunithi nganye yokubeka iliso kwinkqubo ilawulwa kwaye ilawulwa yiyunithi ephambili yokubeka iliso, kwaye ulwazi oluqokelelweyo yiyunithi nganye yokubeka iliso luthunyelwa kwiyunithi ephambili yokubeka iliso ukuze kulawulwe ngokudibeneyo ngokusebenzisa umgca wonxibelelwano we-RS485. Isikrini esiphambili singabonisa ulwazi olwahlukeneyo kwinkqubo, kwaye umsebenzisi angabuza ulwazi lwenkqubo aze aqaphele "umsebenzi omane okude kwisikrini esiphambili sokubonisa isikrini ngokusebenzisa ukuchukumisa okanye ukusebenza kwesitshixo. Ulwazi lwenkqubo lungafikelelwa nge-interface yonxibelelwano lwekhompyutha yomgcini kwisikrini esiphambili. Inkqubo yokubeka iliso ekude. Ukongeza kwiyunithi esisiseko yokulinganisa ngokubanzi, inkqubo inokuxhotyiswa ngeeyunithi ezisebenzayo ezifana nokubeka iliso kwi-insulation, ukuhlolwa kwebhetri, kunye nokubeka iliso kwixabiso lokutshintsha, ezisetyenziselwa ukubeka iliso ngokupheleleyo kwinkqubo ye-DC.
