Yazvino Transformer Secondary Overvoltage Protector
chiyero chekushandisa
Yazvino transformer yechipiri overvoltage dziviriro inonyanya kukodzera kuchinjika mhepo, overcurrent mhepo, kuyerwa kwemhepo, bhazi kuchengetedza mhepo uye backup mhepo yeCT yechipiri rutivi.Iyo inoshandiswa kuvharidzira kupfuudza overvoltage pazasi kukanganisa overvoltage yemidziyo uye kuburitsa simba rekuwedzera, kuitira kuchengetedza sisitimu yedunhu nemidziyo.
Normal sevhisi mamiriro uye installation mamiriro
1. Mamiriro ebasa akajairika
a.Voltage: Mhepo inoramba ichishandiswa pakati pemagetsi ekudzivirira materminals haifaniri kudarika huwandu hwayo
Hombe inoramba ichishanda voltage.
b.Ambient tembiricha: -20℃ ~70℃.
c.Ambient humidity inoshandiswa: <95%RH.
d.Chiyero chekudzivirira kwedzimba: IP20.
e.Pollution level: Chiyero chetsvina panzvimbo yekumisikidza idanho rechipiri.
2. Kuisa mamiriro
a.Kuisa chikamu: zvinoenderana neiyo voltage yekudzivirira level ye overvoltage yekudzivirira mudziyo yakakamurwa kuita mapoka maviri;
b.installation saiti:
