Isebenza njani inkqubo yamandla yeDC?

Amandla e-DC anee-electrode ezimbini, ezintle 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.

Inkqubo ye-DC isetyenziswa 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 zokujonga amandla e-DC, kunye ne-DC yesebe feeder. Uthungelwano olukhulu nokusasazwa kombane wonikezelo lwamandla eDC lubonelela ngamandla okusebenza ngokukhuselekileyo nangokuthembekileyo kwizixhobo zokhuselo lodluliselo, ukubhuqa nokuvalwa kwesekethe, iinkqubo zomqondiso, iitshaja zeDC, uthungelwano lwe-UPSc kunye nezinye iinkqubo.

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 kwityhubhu yokulawula amandla aphezulu kunye nokuphucula ukusebenza kakuhle konikezelo lwamandla eDC. uzinzise umbane. Emva kokudlula kunikezelo lwamandla olawulo lwangaphambili kunye nokucoca i-voltage efunyenweyo izinzile kwaye i-DC yangoku eneripple encinci idluliswa kwityhubhu yokulawula amandla aphezulu elawulwa yisekethe yolawulo ukubuza ngokuchanekileyo nangokukhawuleza uxinzelelo oluphezulu, kwaye ukuchaneka kokulawulwa kwamandla ombane kunye nokusebenza kuya kuhlangabezana nomgangatho. Emva kokuba i-voltage ye-DC ihluzwe sisihluzo se-2, amandla e-DC endiwafunayo afunyenwe. Ukuze sifumane ixabiso lombane wemveliso okanye ixabiso eliqhubekayo langoku endilidingayo, kufuneka senze iisampulu kwaye sibone imveliso yevoltag 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 isiphaluka solawulo/ukhuselo sibona i-voltage engaqhelekanga okanye amaxabiso akhoyo ngoku, isekethe yokhuselo iya kwenziwa isebenze ukwenza umbane weDC ungene kwindawo yokhuseleko. .

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. Ibha yebhasi yokuvala inika amandla kwibar yebhasi yolawulo ngesixhobo sokuhla (olunye uyilo alufuni isixhobo esisezantsi)

DC unikezelo lwamandla

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 kwisistim, kwaye umsebenzisi unokuphinda abuze ulwazi lwenkqubo kwaye aqonde "umsebenzi one kude kwiscreen sokubonisa esona sikrini ngokuchukumisa okanye ngokusebenza kwesitshixo. Ulwazi lwenkqubo lunokufikelelwa ngonxibelelwano lwekhomputha yomncedisi kwi-monitor.Remote inkqubo yokubeka iliso. Ukongeza kumlinganiselo obanzi weyunithi esisiseko, inkqubo inokuxhotyiswa ngeeyunithi ezisebenzayo ezifana nokubekwa esweni kokugquma, ukuhlolwa kwebhetri. kunye nokujonga ixabiso lokutshintsha, ezisetyenziselwa ukubeka esweni ngokubanzi inkqubo yeDC.
