Tsanangudzo Pfupi

Applications

CJW1 yakatevedzana yakangwara universal circuit breakers inogona kushandiswa fir kudzora yakaderera voltage yekugovera mambure uye kuichengeta yakachengeteka.Kuisa mune yakaderera voltage kugovera mapaneru, inoshanda se master switch kuti itambe general kuchengetedza basa.lts technical nature yasvika kune yepasi rose advanced standard yerudzi irworwo rwezvigadzirwa muna 1990s.Inoenderana nedunhu re AC 50Hz, rated volage is 660V (690V) kana pazasi, yakatarwa ikozvino 400A-6300A.

Yakasiyana yakangwara controller inopa akasiyana mabasa.

Iwo anotyora anotevedzera zvinodiwa zveanotevera zviyero, IEC 60947-2, GB14048.2-2001.

Classification

  • Zvinoenderana nekumisikidza: yakagadziriswa uye dhirowa-kunze
  • nematanda: mapango matatu, mapango mana
  • Zvinoenderana nemaitiro ekushanda: mota uye bhuku (kuchengetedza uye kugadzirisa)
  • Zvinoenderana nekuburitswa: inteligent pamusoro pezvino controller, under-voltage instantaneous (kana kunonoka) kuburitswa, uye shunt kuburitswa
  • Iko kugona kweakangwara pamusoro-ikozvino controller:
  • kupatsanura: H mhando (yakajairika), M mhando (yakajairika yakangwara), L mhando (yehupfumi)
  • ine basa rekuremedza kureba kunonoka reverse nguva yekudzivirira kuchengetedza
  • chikamu chimwe chete pasi pekudzivirira basa
  • chiratidzo chebasa: kuseta ikozvino chiratidzo, chiitiko chazvino chiratidzo, imwe neimwe waya voltage chiratidzo (inofanira kutaura sezvaunoraira).
  • Alarm function
  • Self-diagnostics basa
  • Test basa

Environment Condition yeKushanda uye Kuisa

  • Ambient tembiricha: -5 ℃ ~ 40 ℃, uye avhareji tembiricha mumaawa makumi maviri nemana pazasi +35 ℃ (kunze kwemaodha akakosha).
  • Kukwidziridzwa kwenzvimbo yekuisa: ≤2000m.
  • Hunyoro hunyoro: Husingadarike 50% paari tembiricha yepamusoro ye +40 ℃.Ne tembiricha yakaderera, hunyoro hwepamusoro hunogona kubvumidzwa, asi yakaderera avhareji tembiricha muMontn isingadariki +25 ℃ mukati memwedzi wakanyorova, uye huwandu hwepamwedzi hwepakati hwepakati husingadariki 90% mumwedzi iwoyo, uye nekufunga nezvedova. pamusoro pezvinhu, izvo zvaizoonekwa nekuda kwekushanduka kwekushisa.
  • Kudzivirira kusvibiswa: 3 dhigirii.
  • Kuisa zvikamu: Ⅳ zvemasekete makuru eanopwanya, macoils epasi pevolti kuburitswa uye yekutanga dunhu rematransformer;Ⅲ kune mamwe maseketi ekubatsira uye kudzora dunhu.
  • Mabreaker anoshandiswa mungarava uye munzvimbo dzinopisa dzinopisa anogona kushanda zvakajairwa pasina pesvedzero yemhepo ine mwando, mhute yemunyu uye ukuvhu.
  • Mabreaker anoshandiswa mungarava anogona kushanda akavimbika pasi pekudengenyeka kwakajairwa.
  • Iyo breaker inofanirwa kuiswa zvinoenderana nezvinotemerwa mukushandisa bhuku.Kune mabreaker mukushandiswa kwakajairwa, iyo yakatwasuka gradient haipfuure makumi mashanu, kune iyo inoshandiswa pazvikepe, yakatwasuka gradient haipfuuri 22.50.
  • Iyo yekutyora inofanira kuiswa panzvimbo isina chero inoputika yepakati uye conductive dustand isina gasi, iyo inogona kukanganisa simbi kana kuparadza iyo insulation.
  • Iyo breaker inofanirwa kuiswa mukamuri ye switchboard uye gonhi remusuwo rinofanira kugadziriswa nekuwedzera, giredhi redziviriro rinosvika lP40.
