Iyo inoshanda musimboti wesurge dziviriro mudziyo: Iwo ekuvhiya anosunga anowanzo kutsanangurwa seSPDs (Surge Dziviriro Devices), zvigadziriso zvakagadzirirwa kuchengetedza magetsi masisitimu nemidziyo kubva kune inopfuura uye yekupusha overvoltages senge inokonzerwa nekurova kwemheni uye nemagetsi switch. Basa ravo nderokutsausa kubuda kana kufambisa ikozvino kunokonzerwa ne overvoltage kusvika pasi / pasi, nokudaro kudzivirira midziyo yakadzika pasi.SPDs inoiswa mukufanana nemutsara wemagetsi kuti udzivirirwe. Pama mains rated voltage, iwo anofananidzwa nedunhu rakavhurika uye ane yakakwira impedance kumigumo yawo. Muhupo hwekuwedzeredza, iyi impedance inowira kune yakaderera zvakanyanya, kuvhara dunhu kusvika pasi / pasi. Kana iyo overvoltage yapera, impedance yavo inokwira zvakare nekukurumidza kune yekutanga kukosha (yakanyanya kwazvo), ichidzokera kuvhura loop mamiriro. Iyo Type 2 SPD ndiyo huru yekudzivirira sisitimu kune ese yakaderera voltage magetsi ekuisa. Yakaiswa mune imwe neimwe yemagetsi switchboard, inodzivirira kupararira kwe overvoltages mumagetsi ekuisa uye inodzivirira mitoro. Type 2 surge protective devices (SPDs) dzakagadzirirwa kuchengetedza kuisirwa kwemagetsi nemidziyo inonzwisa tsitsi kubva pakusevha zvisina kunanga uye kuve nechokwadi chekudzivirira kwakadzika (Kumusoro). Type 2 surge yekudzivirira zvishandiso zvinopa dziviriro inoshanda kubva kune aya ane simba anokanganisa akasiyana. Ingave munzvimbo yeindasitiri kana muchivakwa chekugara, mhando 2 dziviriro inovimbisa kuchengetedzwa kwekutanga kwekuisa kwako uye zvishandiso. Iwo TRS4 akatevedzana mhando 2 SPDs anowanikwa ane discharge capacity ye10kA, 20KA, 40KA, 60KA mune imwechete-phase kana 3-phase kumisikidzwa uye neakasiyana ma voltages kuitira kuchengetedza chero mhando yemagetsi ekupa system. THOR Type 2 DIN-rail SPD maficha ari kupa nekukurumidza kupisa kwemhinduro uye yakakwana yekucheka-kubvisa basa uye kupa nekukurumidza uye kwakavimbika kudzivirira kune akasiyana emagetsi masisitimu.Uye kugona kwayo kuburitsa zvakachengeteka ikozvino ne8/20 μs waveform. Yakavakwa nehwindo rekukanganisa chiratidzo uye inosarudzika kure alarm yekubata, inogona kutarisa mamiriro ekushanda eSPD pachayo.
