DC simbaine ma electrode maviri, akanaka uye asina kunaka.Iko kukwanisa kwe electrode yakanaka yakakwirira uye kukwanisa kwe electrode yakaipa kwakaderera.Apo ma electrode maviri akabatanidzwa kudunhu, mutsauko unoramba uripo unogona kuchengetwa pakati pemigumo miviri yedunhu, kuitira kuti mumhepo yekunze A ikozvino inoyerera kubva kune yakanaka kusvika kune yakaipa.Kusiyana pakati pemvura yega haigoni kuchengetedza kuyerera kwemvura kwakadzikama, asi nerubatsiro rwepombi kuti irambe ichitumira mvura kubva panzvimbo yakaderera kusvika panzvimbo yakakwirira, imwe misiyano yemvura inogona kuchengetedzwa kuti iite mvura yakadzikama.
TheDC systeminoshandiswa mu hydraulic uye thermal simba zvidyarwa uye akasiyana substations.Iyo DC sisitimu inoumbwa zvakanyanya nemabhatiri mapaketi, ekuchaja zvishandiso, DC feeder mapaneru, DC yekugovera makabati, DC magetsi ekutarisa michina, uye DC bazi rinodyisa.Iyo yakakura uye yakagovaniswa DC magetsi emagetsi network inopa yakachengeteka uye yakavimbika simba rekushanda kune relay kuchengetedza zvishandiso, wedunhu breaker kutsika nekuvhara, masisitimu emasaini, DC charger, UPS, kutaurirana uye mamwe ma subsystems.
Pane misimboti miviri yekushanda, imwe ndeye kushandisa mains simba kushandura AC kuita DC;imwe yacho inoshandisa DC.
AC kusvika kuDC
Kana iyo mains voltage ichishandurwa kuita yakagadziridzwa voltage kuburikidza neinopinza switch uye transformer yakavhurwa, inopinda pre-yakadzikama dunhu.Iyo pre-stabilizing circuit ndeyekuita preliminary voltage regulation pane inodiwa inobuda voltage, uye chinangwa chayo kudzikisa iyo yakakwirira-simba kugadzirisa.Iyo chubhu yemagetsi inodonha pakati pekupinza uye kubuda kwechubhu inogona kuderedza mashandisirwo emagetsi eiyo yepamusoro-simba inodzora chubhu uye kunatsiridza kushanda zvakanaka kweiyo DC magetsi.kudzikamisa voltage.Mushure mekupfuura nepamberi pemagetsi emagetsi uye sefa ①, iyo voltage yakawanikwa yakagadzikana uye iyo DC ikozvino ine diki ripple inopfuudzwa nepamusoro-simba regulating chubhu inodzorwa nedunhu rekutonga kuti inyatso uye nekukurumidza kubvunza kudzvanywa kwepamusoro, uye kurongeka kwemagetsi uye kuita zvinosangana nechiyero.Mushure mekunge iyo DC voltage yapepetwa nesefa ②, iyo inobuda DC simba randinoda rinowanikwa.Kuti tiwane kukosha kwevoltage inobuda kana kukosha kwazvino kwandinoda, isu tinodawo kuenzanisa uye kuona kukosha kwevoltage yekubuda uye kukosha kwazvino.Uye kuiendesa kune yekudzora / yekudzivirira dunhu, iyo yekudzora / yekudzivirira dunhu inofananidza uye inoongorora iyo yakaonekwa yakabuda voltage kukosha uye kukosha kwazvino kukosha kwakaiswa nevoltage / ikozvino kuseta dunhu, uye inotyaira pre-regulator wedunhu uye yakakwirira-simba. kugadzirisa chubhu.Iyo DC yakagadzikana magetsi inogona kuburitsa voltage uye zvazvino hunhu hwatinoisa, uye panguva imwe chete, kana iyo yekudzora / yekudzivirira yedunhu inoona abnormal voltage kana hunhu hwazvino, dunhu redziviriro rinoitwa kuti riite kuti magetsi eDC apinde mukati. kudzivirira nyika.

Iwo maviri AC mitsara inopinda inoburitsa imwe AC (kana imwe chete AC iri kuuya mutsara) kuburikidza neiyo switching mudziyo kupa simba kune yega yekuchaja module.Iyo yekuchaja module inoshandura iyo yekupinza matatu-chikamu AC simba kuita DC simba, inochaja bhatiri, uye inopa simba kune inovhara bhazi mutoro panguva imwe chete.Bhazi rekuvhara rinopa simba kune bhari yekudzora kuburikidza nechitsiko-pasi (mamwe magadzirirwo haadi danho-pasi mudziyo).

Yese yekutarisa unit musystem inotungamirwa uye inodzorwa neiyo main monitoring unit, uye ruzivo rwunounganidzwa nechero chikamu chekutarisa runotumirwa kune main monitoring unit yekubatana manejimendi kuburikidza neRS485 yekutaurirana mutsara.Iyo huru yekutarisa inogona kuratidza ruzivo rwakasiyana muhurongwa, uye mushandisi anogona zvakare kubvunza iyo sisitimu ruzivo uye kuona iyo "ina kure kure" basa pane main monitor yekuratidzira skrini kuburikidza nekubata kana kiyi mashandiro.Irwo ruzivo rwehurongwa runogonawo kuwanikwa kuburikidza neyekugamuchira komputa yekukurukurirana interface pane main monitor.Remote monitoring system.Pamusoro peiyo yakazara kuyerwa kwekutanga unit, iyo sisitimu inogona zvakare kuve neanoshanda mayuniti senge insulation yekutarisa, kuongorora bhatiri, uye switching kukosha yekutarisa, iyo inoshandiswa kunyatso tarisa iyo DC system.
