Ongororo Investigation yeChiringidziro Chekudzidzira kweChikoro I SPDs pasi peC10 / 350μs uye 8 / 20μs Pfungwa dzeMvura
Zvimwe zvinodzivirira zvipfeko (SPDs) zvinodiwa kuti zviongorwe pasi pemhepo dzisina simba dzinoshandiswa kunyanya nema waveforms a 8 / 20 ms uye 10 / 350 ms. Zvisinei, nekuvandudzika kwezvinhu zveSDD, kushanda uye kumira kukwanisa kweSSPs pasi pemaitiro akadaro emuedzo unodikanwa kutsvaga tsvakurudzo yakawanda. Kuti uongorore uye uenzanise nekumira kwemaikirwo eSPDs pasi pe8 / 20 ms uye 10 / 350 ms mhepo inoputika, miedzo inowanikwa pamhando mitatu yemidziyo-metal-oxide varistors (MOVs) inoshandiswa kukirasi I SPDs. Zvigumisiro zvinoratidza kuti maMoV ane marefu emagetsi anowedzera zviri nani kumisa pasi pe8 / 20ms mafungiro emhepo ikozvino, asi kupedzisa pasi pe10 / 350ms kufungidzira ikozvino kwakatarisana. Pasi pa 10 / 350 ms wamangwana, kusakona kweM MOV kwakabatana nehuwandu hwemagetsi eunikirini yevhesi pasi pekutsvaga kumwe. Kupera ndiyo iyo mafomu makuru ekuparara pasi pe10 / 350ms ikozvino, iyo inogona kutsanangurwa seimwe rutivi rweMAPV plastiki encapsulation uye peji ye electrode iri kubvisa. Ablation yeZnO nyaya, yakakonzerwa neflashover pakati pe electrode sheet neZnO surface, yakaonekwa pedyo neElectrode MOV.
Saji yekudzivirira michina (SPDs) yakabatana kune lowvoltage magetsi masisitimu, kufonera pamwe nemasaini network zvinofanirwa kuedzwa pasi pezvinodiwa neIEC neIEEE […]

Ndeipi nzvimbo yekudzivirira magetsi uye nei ichikosha?
Iyo mheni yekudzivirira kwemhepo pfungwa inotangira uye inotsanangurwa muIEC 62305-4 chiyero icho chiri chinzvimbo chepasi rose chekudzivirira kwemheni. Pfungwa yeLPZ inoenderana nepfungwa yekudzora zvishoma nezvishoma magetsi emagetsi kune akachengeteka kuti asazokanganisa kukuvadzwa kwetemu.
Ngatione muenzaniso wakakosha.
Saka chii chinonzi nzvimbo dzakasiyana-siyana dzekudzivirira magetsi zvinoreva?
LPZ 0A: Inzvimbo isina kuchengetedzwa iri kunze kwechivako uye yakafumurwa kunongedza mheni yakananga. MuLPZ 0A, hapana chidziviriro chinopesana nemagetsi zvinokanganisa LEMP (Mheni Electromagnetic Pulse).
