Iyo DC simba system inoshanda sei?

DC simba rine maelectrode 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.

Iyo DC sisitimu inoshandiswa mu hydraulic uye inopisa magetsi 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, UPSc ommunications 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 nepakati-yakatemerwa magetsi ekupa uye kusefa 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 iyo voltage regulation kurongeka uye kuita kuchasangana nechiyero. Mushure meiyo 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 inobuda voltag ongororo 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 ikozvino kukosha kwatinoisa. uye panguva imwe chete, kana iyo control / yekudzivirira yedunhu inoona abnormal voltage kana yazvino kukosha, dunhu redziviriro richaitwa kuita kuti DC magetsi apinde munzvimbo yekudzivirira. .

DC simba rekupa

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. Iyo yekuvhara bhazi bhawa inopa simba kune yekudzora bhazi bar kuburikidza nedanho-pasi mudziyo (mamwe madhizaini haadi nhanho-pasi-chishandiso)

DC simba rekupa

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 system ruzivo uye kuona iyo "ina kure kure basa pane huru yekutarisa skrini yekuratidzira kuburikidza nekubata kana kiyi mashandiro. Ruzivo rwehurongwa runogonawo kuwanikwa kuburikidza neyakagashira kombiyuta yekutaurirana interface pane main monitor.Remote monitoring system. Pamusoro peiyo yakazara kuyerwa kwekutanga chiyero, sisitimu inogona zvakare kuve neanoshanda mayuniti akadai seyekuvharisa, kuongorora bhatiri uye switching kukosha kwekutarisa, ayo anoshandiswa kunyatso tarisa iyo DC system.
