Acereare Magetsi matsva ARM5 akateedzana kaviri kuputsa epurasitiki-kesi redunhu rinotyora
I. Chigadzirwa chidimbu
ARM5 yakatevedzana yakaumbwa kesi kaviri-break redunhu breaker chigadzirwa chitsva chichangobva kugadzirwa nekambani yedu. Dhizaini yayo inoratidza yazvino yazvino yekumisikidza musimboti uye yekugadzira tekinoroji, uye ine compact, modular, yakakwirira kutyora, zero arcing, girinhi uye nharaunda kuchengetedza maitiro. Mutambo wedunhu wakakodzera AC 50Hz/60Hz dunhu rine rated insulation voltage ye1000V, yakanyanya kurongeka kushanda voltage ye690V, yakanyanya kupaza simba icu uye ics inosvika 200kA uye yakayerwa ikozvino kubva 32A kusvika 630A kugadzira, kutyora uye kutakura yakayerwa ikozvino, uye inogona kuchengetedza zvakavimbika mitsara nemidziyo yemagetsi kana yakawandisa, pfupi pfupi uye undervoltage. Inogona zvakare kushandiswa kune infrequent kutanga, kuwandisa, pfupi dunhu uye undervoltage kudzivirira kwemota.
II. Zvibereko zvechigadzirwa / mapoinzi ekutengesa
1. ARM5 yakatevedzana yakawedzera kuvandudza kuvimbika kwemagetsi, uye ine zvakanakira modularization, diki saizi, yakakwira yekutyoka simba, pfupi arcing, yakakwirira kuvimbika, yakanaka kuchengetedza kwezvakatipoteredza, yakazara mabasa, nezvimwe.
2. short-circuit breaking capacity pa AC400V, L rudzi: 100KA, M rudzi: 150KA, H rudzi: 200KA. 100KA inoshandiswa kune zvikumbiro zvine chekuita nepamusoro zvinodiwa, mitsara yekugadzira maindasitiri, uye midziyo yemagetsi yakakosha. 150KA-200KA ine indasitiri inotungamira kutyora kugona uye inogona kushandiswa muindasitiri inorema uye yakakosha indasitiri.
3. Iyi nhevedzano yezvishongedzo inogona kuiswa zviri nyore munzvimbo inoenderana yedunhu breaker uye ine yakavimbika kushanda kushanda. Iyo shunt kuburitswa, undervoltage kuburitswa uye yekubatsira kuonana zvese zvinogadzirwa kuita akasiyana mamodule.
4. Thermal magnetic release yeARM5-160, 250, 400 uye 630 circuit breakers inogona kugadziriswa kuti isangane nezvinodiwa zvekudzivirira.
Ⅲ. Kuburitsa tsananguro yemuenzaniso
D: Kudzivirirwa kwekugovera simba; MA: kuchengetedzwa kwemotokari
Rated current
TM: thermomagnetic kuburitswa
Iyo yekumisikidza yekudzivirira yakawandisa inogadziriswa 1, uye kukosha kwekumisikidza kwepfupi-sekete dziviriro inogadziriswa kana yakagadziriswa 2;

Main mabasa uye maitiro
I. Pneumatic kudzivirira mudziyo
Apo dunhu rinoputika nehombe huru, gasi mubhokisi rekubatanidza bhokisi rinokurumidza kumanikidzwa, uye chigadziro chekudzivirira kwepneumatic chinokurumidza kuchinja chigadziko chekushanda pasi pemhepo yakasimba yemhepo, ichideredza zvikuru kukanganisa kwekuputsa ikozvino kune zvimwe zvikamu zvemagetsi uye mabhazi.
Magnetic blow design:iyo ikozvino inoyerera kuburikidza neyakagadziriswa kusangana kuti ibudise magetsi emagetsi, ayo anoumba annular magnetic field arc ane iron core uye anokurumidza kupinda mukamuri yekudzima arc pasi pechiito chemagnetic field, iyo inobatsira kukurumidza kuputsa ikozvino.
Iyo ine musoro dhizaini dhizaini yekufamba uye yakagadziriswa madhizaini inoita iyo pfupi yedunhu kukosha kwepamusoro uye simba reiyi nhevedzano yezvigadzirwa I²t idiki pane yaitarisirwa.
Kushanda musimboti: yazvino inoyerera ichibva kune yakagadziriswa yekubata 1, inoyerera ichibva kune yakagadziriswa yekubata 2 kuburikidza inofamba, yakagadziriswa sirivha yekubata uye inofamba yekubata. Iyo inofamba inobata inokurumidza kudimbura pasi pechiito chesimba remagetsi repulsion simba (Holm force neLorentz force) kuvandudza kumhanya kwekupwanya.
Mhepo inovhuvhuta dhizaini: kana iyo pfupi yedunhu yakakura ikozvino inoitika mudunhu, iyo gasi inogadzira zvikamu zvinogadzira imwe gasi pasi pekupisa kwakanyanya kwearc, kudzvanywa kwemhepo mubhokisi rekusangana kunowedzera nekukurumidza, uye kuyerera kwemhepo kunomhanya kunogona. kuumbwa kuburikidza nemhepo yekubuda kwekamuri yekudzima arc, iyo inogona kunyatso kudzima arc.
