115V920Ah DC Power System
Chiindiyo DC Power System?
A DC magetsi sisitimu inoshandisa yakananga ikozvino (DC) kupa simba kumidziyo yakasiyana siyana nemidziyo.Izvi zvinogona kusanganisira masisitimu ekugovera magetsi seaya anoshandiswa munharembozha, nzvimbo dzedata uye maindasitiri ekushandisa.Masisitimu emagetsi eDC anowanzo shandiswa mumamiriro ezvinhu panodiwa magetsi akatsiga uye akavimbika, uye kushandisa magetsi eDC kunonyanya kushanda kana kushanda kupfuura kuchinjisa ikozvino (AC) simba.Aya masisitimu anowanzo sanganisira zvinhu zvakaita sezvekugadziridza, mabhatiri, inverters, uye voltage regulator kubata nekudzora kuyerera kweDC simba.
Iyo basa musimboti weiyo DC system
AC yakajairika kushanda mamiriro:
Kana iyo AC inopinza ye system inopa simba zvakajairika, iyo AC yekugovera magetsi unit inopa simba kune yega yega module yekugadziridza.Iyo yakakwirira-frequency rectification module inoshandura AC simba kuita DC simba, uye inoiburitsa kuburikidza nemudziviriri mudziyo (fuse kana wedunhu breaker).Kune rimwe divi, inochaja bhatiri paki, uye kune rimwe divi, inopa yakajairika simba rekushanda kune DC mutoro kuburikidza neDC simba rekugovera feed unit.
AC simba kurasikirwa kushanda mamiriro:
Kana iyo sisitimu yeAC yekupinda ikatadza uye simba radzimwa, iyo yekugadziridza module inomira kushanda, uye bhatiri rinopa simba kuDC mutoro pasina kukanganisa.Iyo yekutarisa module inocherekedza kubuda kwemagetsi uye ikozvino kwebhatiri munguva chaiyo, uye kana bhatiri richibuda kune yakamira yekupedzisira voltage, iyo yekutarisa module inopa alarm.Panguva imwecheteyo, iyo yekutarisa module inoratidza uye inogadzirisa iyo data yakakwidzwa nemagetsi kugovera yekutarisa wedunhu nguva dzese.
