Amandla eDCinee-electrode ezimbini, ezilungileyo nezimbi.Ubunakho be-electrode elungileyo buphezulu kwaye amandla e-electrode engalunganga aphantsi.Xa i-electrode ezimbini zixhunywe kwisekethe, ukungafani okukhoyo rhoqo kunokugcinwa phakathi kweziphelo ezimbini zesekethe, ukwenzela ukuba kwisekethe yangaphandle i-A yangoku ihamba ukusuka kwi-positive ukuya kwi-negative.Umahluko phakathi komgangatho wamanzi wedwa awukwazi ukugcina ukuhamba kwamanzi okuzinzileyo, kodwa ngoncedo lwempompo ngokuqhubekayo ukuthumela amanzi ukusuka kwindawo ephantsi ukuya kwindawo ephakamileyo, umlinganiselo othile wamanzi unokugcinwa ukuze wenze ukuhamba kwamanzi okuzinzileyo.
IInkqubo yeDCisetyenziswa kwizityalo zamandla oxinzelelo lwe-hydraulic kunye ne-thermal kunye nezikhululo ezahlukeneyo.Inkqubo ye-DC iqulunqwe ikakhulu ngeepakethi zebhetri, izixhobo zokutshaja, iiphaneli ze-DC feeder, iikhabhathi zokusasazwa kwe-DC, izixhobo zokujongwa kwamandla e-DC, kunye ne-DC yesebe feeder.Uthungelwano olukhulu kunye nokusasazwa kombane wombane weDC ubonelela ngamandla okusebenza ngokukhuselekileyo nangokuthembekileyo kwizixhobo zokhuseleko lodluliselo, ukunqunqa nokuvala i-breaker circuit, iinkqubo zesignali, iitshaja zeDC, i-UPS, unxibelelwano kunye nezinye ii-subsystems.
Kukho imigaqo emibini yokusebenza, omnye kukusebenzisa amandla amakhulu ukuguqula i-AC ibe yi-DC;enye isebenzisa i-DC.
I-AC ukuya kwi-DC
Xa i-voltage ye-mains iguqulwa ibe yi-voltage eyilwe ngokutshintsha igalelo kwaye i-transformer ivuliwe, ingena kwisiphaluka sangaphambili sokuzinzisa.Isekethe yangaphambi kokuzinzisa kukwenza ummiselo wokuqala wombane kumbane ofunekayo wokuphuma, kwaye injongo yayo kukunciphisa uhlengahlengiso lwamandla aphezulu.Ukuhla kwamandla ombane wetyhubhu phakathi kwegalelo kunye nemveliso yetyhubhu kunokunciphisa ukusetyenziswa kwamandla etyhubhu yokulawula amandla aphezulu kunye nokuphucula ukusebenza kakuhle konikezelo lwamandla lweDC.uzinzise umbane.Emva kokudlula kunikezelo lwamandla olawulo lwangaphambili kunye nesihluzi ①, i-voltage efunyenweyo izinzile kwaye i-DC yangoku eneripple encinci idluliswa kwityhubhu yokulawula amandla aphezulu elawulwa yisekethe yolawulo ngokuchanekileyo nangokukhawuleza ukubuza uxinzelelo oluphezulu, kunye nokuchaneka kokulawulwa kwamandla ombane kunye nokusebenza kuya kuhlangabezana nomgangatho.Emva kokuba i-voltage ye-DC ihluzwe sisihluzo ②, amandla e-DC endiwafunayo afunyenwe.Ukuze sifumane ixabiso lombane wemveliso okanye ixabiso eliqhubekayo langoku endilidingayo, kufuneka sithathe iisampulu kwaye sibone ixabiso lombane wemveliso kunye nexabiso langoku.Kwaye uyidlulisele kwisekethe yokulawula / yokukhusela, isiphaluka solawulo / sokukhusela sithelekisa kwaye sihlalutya ixabiso le-voltage yesiphumo esifunyenweyo kunye nexabiso langoku kunye nexabiso elibekwe yi-voltage / i-current setting circuit, kwaye iqhuba i-pre-regulator circuit kunye ne-high-power. ityhubhu yokulungelelanisa.Unikezelo lwamandla oluzinzile lwe-DC lunokuvelisa amandla ombane kunye namaxabiso angoku esiwabekayo, kwaye kwangaxeshanye, xa isekethe yolawulo/yokukhusela ibona i-voltage engaqhelekanga okanye amaxabiso akhoyo, isekethe yokhuselo iya kwenziwa isebenze ukwenza umbane weDC ungene ilizwe lokhuseleko.
DC unikezelo lwamandla
Imigca emibini ye-AC engenayo ikhupha i-AC enye (okanye enye kuphela i-AC engenayo umgca) ngokusebenzisa isixhobo sokutshintsha ukubonelela amandla kwimodyuli nganye yokutshaja.Imodyuli yokutshaja iguqula igalelo lesigaba sesithathu se-AC amandla kumandla eDC, ihlawulisa ibhetri, kwaye inike amandla kumthwalo wokuvala ibhasi ngaxeshanye.I-busbar yokuvala inika amandla kwi-busbar yokulawula ngokusebenzisa isixhobo esisezantsi (ezinye ziyilo azifuni isixhobo sokuhla).

Iyunithi nganye yokubeka iliso kwisistim ilawulwa kwaye ilawulwa yiyunithi ephambili yokubeka iliso, kwaye ulwazi oluqokelelwe yiyunithi nganye yokubeka iliso ithunyelwa kwiyunithi ephambili yokubeka iliso kulawulo olumanyeneyo ngomgca wonxibelelwano we-RS485.Imonitha ephambili inokubonisa ulwazi olwahlukeneyo kwinkqubo, kwaye umsebenzisi unokuphinda abuze ulwazi lwenkqubo kwaye aqonde umsebenzi "we-remote ezine" kwisikrini esiphambili sokubonisa esweni ngokucofa okanye ngokusebenza kwesitshixo.Ulwazi lwenkqubo lunokufikelelwa ngonxibelelwano lwekhomputha yomncedisi kwimonitha ephambili.Inkqubo yokuhlola ekude.Ukongeza kumlinganiselo obanzi weyunithi esisiseko, inkqubo inokuxhotyiswa ngeeyunithi ezisebenzayo ezifana nokujongwa kwe-insulation, ukuhlolwa kwebhetri, kunye nokujonga ixabiso lokutshintsha, ezisetyenziselwa ukubeka esweni ngokubanzi inkqubo ye-DC.
