Sisitimu yemagetsi yeDC inoshanda sei?

Simba reDC rine maerekitironi maviri, akanaka neasina kunaka. Simba reerekitironi rakanaka rakawanda uye simba reerekitironi risina kunaka rakaderera. Kana maerekitironi maviri akabatana nedunhu, musiyano wesimba unogara uripo unogona kuchengetedzwa pakati pemagumo maviri edunhu, kuitira kuti mudunhu rekunze A current inoyerera kubva pakanaka kuenda pakaipa. Musiyano uripo pakati pehuwandu hwemvura chete haugone kuchengetedza kufamba kwemvura kwakasimba, asi nerubatsiro rwepombi kuti mvura irambe ichitumirwa kubva panzvimbo yakaderera kuenda panzvimbo yakakwirira, musiyano wehuwandu hwemvura unogona kuchengetedzwa kuti ugadzire kufamba kwemvura kwakasimba.

Sisitimu yeDC inoshandiswa muma hydraulic ne thermal power plants pamwe nema substations akasiyana-siyana. Sisitimu yeDC inonyanya kuumbwa nema battery packs, ma charging devices, ma DC feeder panels, ma DC distribution cabinet, ma DC power monitoring devices, uye ma DC branch feeders. Network yemagetsi yeDC yakakura uye yakapararira inopa simba rekushanda rakachengeteka uye rakavimbika re relay protection devices, circuit breaker tripping and closing, ma signal system, ma DC chargers, ma UPSc communications nedzimwe subsystems.

Pane nzira mbiri dzekushanda nadzo, imwe ndeyekushandisa simba remagetsi kushandura AC kuita DC; imwe inoshandisa DC

AC kuenda kuDC

Kana magetsi makuru ashandurwa kuita voltage yakagadzirwa kuburikidza ne switch yekupinda uye transformer yabatidzwa, inopinda mudunhu risati ragadzikana. Dunhu risati ragadzikana nderekuita preliminary voltage regulation pavoltage inodiwa, uye chinangwa charo ndechekuderedza high-power adjustment. Kudonha kwevoltage yechubhu pakati peinput ne output yechubhu kunogona kuderedza kushandiswa kwesimba kwe high-power regulating chubhu uye kuvandudza kushanda kweDC power supply. kudzikamisa voltage. Mushure mekupfuura nepakati pe pre-regulated power supply ne filter, voltage inowanikwa inogadzikana uye DC current ine ripple diki inopfuudzwa ne high-power regulating chubhu inodzorwa ne control circuit kuti ibvunze nekukasika uye nekukurumidza kudzvanywa kwepamusoro, uye voltage regulation accuracy uye performance zvichasangana ne standard. Mushure mekunge DC voltage yaseferwa ne filter 2, output DC power yandinoda inowanikwa. Kuti tiwane output voltage value kana constant current value yandinoda, tinofanirawo kuongorora uye kuona output volttag evalue uye current value. Uye ichiendesa kudunhu rekudzora/kudzivirira, dunhu rekudzora/kudzivirira rinoenzanisa nekuongorora kukosha kwevoltage inobuda uye kukosha kwezvino nemutengo wakaiswa nedunhu rekugadzika voltage/current, uye rinotyaira dunhu repre-regulator uye chubhu yekugadzirisa ine simba guru. DC stabilized power supply inogona kuburitsa voltage uye kukosha kwezvino kwatinoisa. Uye panguva imwe chete, kana dunhu rekudzora/kudzivirira rikaona voltage isina kujairika kana kukosha kwezvino, dunhu rekudzivirira rinozoshanda kuti DC power supply ipinde mumamiriro ekudzivirira.

Mitsetse miviri yeAC inopinda inoburitsa AC imwe chete (kana tambo imwe chete yeAC inopinda) kuburikidza neswitching device kuti ipe simba kune yega yega charging module. Charging module inoshandura input three-phase AC power kuita DC power, inochaja bhatiri, uye inopa simba kune closing bus load panguva imwe chete. Closing bus bar inopa simba kune control bus bar kuburikidza ne step-down device (mamwe madhizaini haadi step-down device)

Chikamu chimwe nechimwe chekutarisa chiri musystem chinotungamirwa uye chinodzorwa nechikamu chikuru chekutarisa, uye ruzivo rwunounganidzwa nechikamu chimwe nechimwe chekutarisa runotumirwa kuchikamu chikuru chekutarisa kuti chive nehutongi hwakabatana kuburikidza netambo yekutaurirana yeRS485. Chinotarisisa chikuru chinogona kuratidza ruzivo rwakasiyana musystem, uye mushandisi anogona zvakare kubvunza ruzivo rwesystem uye kuona "mabasa mana ari kure pachidzitiro chikuru chekutarisa kuburikidza nekubata kana kushanda kwekiyi. Ruzivo rwesystem runogonawo kuwanikwa kuburikidza neinterface yekukurukurirana kwekombuta yehost pane chikuru chekutarisa. Remote monitoring system. Kuwedzera kune yakazara yekuyera basic unit, system inogona zvakare kuve ne functional units dzakadai se insulation monitoring, battery inspection, uye switching value monitoring, iyo inoshandiswa kunyatsoongorora DC system.
