SPD backup dziviriro T1 nhevedzano
Pfupiso yezvigadzirwa
Zvichienderana nezvinodiwa neGB18802.1, GB50057 uye Q/THQBOO1-2013, chikamu chepamberi cheSPD loop chinofanira kubatanidzwa nemidziyo yekudzivirira inodarika mwero inodiwa nemugadziri wezvidziviriro zve surge.
Nekuti fuse iripo uye miniature circuit breaker hazvigone kuenderana neSPD, kana magetsi asina kunaka kana SPD ikaora yobva yakundikana, moto nemidziyo zvinokuvadzwa nemheni, izvo zvakakanganisa zvakanyanya mashandiro enguva dzose ekugadzirwa!
Parizvino, nhamba yakakura yema "miniature circuit breakers" anoshandiswa pamwe chete neSPD haagone kuenzaniswa muzvikamu zvina zvinotevera:
1. Kuvhunduka kwemagetsi emheni kuri nyore kwazvo kukuvadza-kudzivirira mheni hakushande;
2. Kuwanda kwemagetsi emagetsi anobuda mumagetsi - kuvimbika kwekudzivirira mheni kwemidziyo kunoderera;
3. Kutenderera kwesimba pasina tambo hakukanganisi-simba remagetsi harina kujairika uye SPD iri kutsva;
4. Kurova kwemheni kunokanganisa netsaona - dziviriro yemheni inokundikana.
Tichifunga nezvemamiriro ezvinhu aripo ekuti hapana mudziyo wekudzivirira wakanyanya weSPD unotsigira indasitiri yekudzivirira mheni, mushure memakore matatu ekutsvaga nekugadzira uye anopfuura gore rimwe ekuyedza kwakasiyana-siyana kwekufananidzira kwezvakatipoteredza murabhoritari, zvaratidzwa kuti SPD backup protector (SCB)
1. Kufamba kweSPD frequency freewheeling ukoshi 4A
2. Kushanda kwemhepo kusingafambi kwakakura kupfuura 40kA (8/20);
3. Kuora mwoyo kwemagetsi kunokonzerwa nemagetsi. Gadzirisa mamiriro ezvinhu aripo ekuti SPD haina michina yekudzivirira magetsi akawandisa; Kushanda pamwe chete pakati peSCB neSPD ndekwekuona kuti SPD haibati moto uye kuti magetsi anopisa haagumburwi.
Basa uye huwandu hwekushandiswa
Chinobvisa magetsi chekunze cheSPD chakabatana muchikamu cheSPD, uye mudziyo wekuronga magetsi wemukati unoshandiswa kuita kuti magetsi ashande nekukurumidza; Mheni yepamusoro haikanganisike. Kubudirira kwebasa rekudzivirira moto wemagetsi mashoma eSPD uye kudzivirira moto wemagetsi eSPD nguva dzose; Zvigadzirwa zveSCB zvinongoshandiswa chete pakudzivirira magetsi eSPD loop, kana kuchengetedza magetsi ekuchengetedza. Ndapota musazvishandise mune dzimwe nguva.
Chinhu chechigadzirwas
1. Maitiro ekugumburwa anodzorwa neparamita, anogona kuita kuti pave nekuputsa kwemagetsi kwakasarudzwa;
2. Mhepo inosara yemagetsi inongoerekana yadonha, inogona kuenzaniswa neye fuse;
3. Kubata nesimba rakawanda, nehupenyu hurefu hwebasa;
4. Chimiro chakatyoka-kadiki, vhoriyamu diki, zviri nyore kuti magetsi ashaye simba kuona SPD;
5. Kunyatsotsanangura, zvichizadzisa zvinodiwa zvekutsigira SPD pamazinga eT1, T2 uye T3.
Kuisa clamp njanji ye6.35mm kunosangana nezvinodiwa pasi rese.
