SPD yePower Supply System Series Sarudzo Yekutungamira

Kuiswa kweSPD panzvimbo yega yega yekudzivirira mheni, zvinoenderana neyakajairwa kutaridzika kwemagetsi yakaderera, ita kupatsanurwa kwemidziyo yemagetsi zvinoenderana neiyo pamusoro pevoltage chikamu, insulation yayo inomira impulse voltage level inogona kuona kusarudzwa kweSPD.Zvinoenderana nechiyero chekutaridzika kwemagetsi emagetsi mashoma, ita kupatsanurwa kwemidziyo yemagetsi zvinoenderana neiyo pamusoro pevoltage chikamu seyero yechiratidzo, nhanho yekurodha, yekugovera uye yekudzora level, magetsi emagetsi.Insulation yaro inomira nhanho yemagetsi: 1500V, 2500V, 4000V, 6000V.Sezvinei kune yakadzivirirwa yekumisikidza nzvimbo yakasiyana uye yakasiyana mheni yazvino yenzvimbo dzakasiyana dzekudzivirira mheni, kuona nzvimbo yekuisa yeSPD yemagetsi ekupa uye kupaza-pamusoro pesimba.

Iyo yekumisikidza kureba pakati peyega yega SPD haifanirwe kudarika 10m, chinhambwe chiri pakati peSPD nemidziyo yakadzivirirwa chinofanira kunge chipfupi sezvinobvira, kwete kupfuura gumi.Kana nekuda kwekuganhurirwa kwechinzvimbo chekuisa, haigone kuvimbisa chinhambwe chekuisa, saka unofanirwa kuisa decoupling chikamu pakati peyega yega SPD, ita iyo mushure mekirasi SPD kuchengetedzwa nekirasi yekutanga SPD.Mune yakaderera voltage magetsi ekupa system, kubatanidza inductor kunogona kuzadzisa chinangwa chekubatanidza.

SPD yemagetsi ekupa system yakatarwa yekusarudza musimboti

Max.inoenderera ichishanda voltage: yakakura kupfuura yakachengetedzwa midziyo, iyo max system.kuenderera mberi kushanda voltage.

TT Sistimu: Uc≥1.55Uo (Uo yakaderera voltage sisitimu kune isina mutsetse voltage)

TN System: Uc≥1.15Uo

IT System: Uc≥1.15Uo (Uo yakaderera voltage system kumutsara voltage)

Voltage Dziviriro Level: yakaderera pane iyo insulation inomira impulse voltage yemidziyo yakadzivirirwa

Yakatemerwa discharge ikozvino: yakatemerwa maererano nemamiriro emheni yenzvimbo yakaiswa uye nzvimbo yekudzivirira mheni.
