I. Pfupiso yezvigadzirwa
ARM5 nhevedzano Nyaya Yakaumbwa Chinopwanya mativi maviri (double-break circuit breaker) chigadzirwa chitsva chakagadzirwa nekambani yedu. Dhizaini yacho inoratidza musimboti wezvino uno wekugadzirisa magetsi uye tekinoroji yekugadzira, uye ine hunhu hwekuchengetedza hudiki, hwakafanana, hwakanyanya kupwanya, husina kusimba, husina kusimba uye hwekuchengetedza nharaunda. Chinopwanya mativi chakakodzera AC 50Hz/60Hz circuit ine voltage yekudzivirira magetsi ye1000V, voltage yekushanda yepamusoro ye690V, kugona kukuru kwekuparara kwemagetsi iCU ne ics kusvika ku200kA uye simba remagetsi rakatorwa kubva pa32A kusvika ku630A kugadzira, kupwanya uye kutakura simba remagetsi rakatorwa, uye inogona kuchengetedza tambo nemidziyo yemagetsi kana paine overload, short circuit uye undervoltage. Inogona zvakare kushandiswa kudzivirira mota kubva pakutanga, overload, short circuit uye undervoltage.
II. Zvakanakira chigadzirwa/poindi dzekutengesa
1. Nhevedzano dzeARM5 dzakawedzera kuvimbika kwemagetsi, uye dzine zvakanakira zve modularization, saizi diki, kugona kukuru kupwanya, kupfupika kwearcing, kuvimbika kwakanyanya, kuchengetedzwa kwakanaka kwezvakatipoteredza, mabasa akazara, nezvimwewo.
2. Kukwanisa kupwanya ma "short-circuit" paAC400V, L mhando: 100KA, M mhando: 150KA, H mhando: 200KA. 100KA inoshandiswa pakushandisa zvine zvinodiwa zvepamusoro, mitsetse yekugadzira maindasitiri, uye michina yemagetsi yakakosha. 150KA-200KA ine kugona kupwanya maindasitiri kuri pamberi uye inogona kushandiswa muindasitiri yakakura uye indasitiri yakakosha.
3. Zvishongedzo izvi zvinogona kuiswa zviri nyore munzvimbo inoenderana necircuit breaker uye zvine mashandiro akavimbika.Hunt release, undervoltage release uye assistant contact zvese zvinogadzirwa kuita mamodule akasiyana.
4. Kuburitswa kwemagineti eARM5-160, 250, 400 uye 630 circuit breakers kunogona kugadziriswa kuti kuenderane nezvinodiwa zvekudzivirira.

TM: kuburitswa kwethermomagnetic
Kugadzika kwekudzivirira zvakanyanya kunogadziriswa 1, uye kukosha kwekugadzirisa kwekudzivirira kwepfupi kunogadziriswa kana kugadziriswa 2;

I. Mudziyo wekudzivirira mweya
Kana dunhu rikatyoka nemagetsi makuru, gasi riri mubhokisi re contact unit rinomanikidzwa nekukurumidza, uye mudziyo wekudzivirira mweya unochinja-chinja chivharo che operating mechanism pasi pekumanikidzwa kwakasimba kwemhepo, zvichideredza zvikuru kukuvara kwemagetsi anotyoka kune zvimwe zvikamu zvemagetsi nemabhazi.
Dhizaini yemagetsi inoputika: magetsi anoyerera nepanosangana zvinhu kuti agadzire sosi yemagetsi, iyo inoumba arc yemagnetic field ine core yesimbi uye inopinda nekukurumidza mukamuri yekudzima arc pasi pesimba remagnetic field, izvo zvinobatsira kupwanya magetsi nekukurumidza.
Kugadzirwa kwakanaka kwezvishandiso zvinofamba uye zvakagadziriswa kunoita kuti kukosha kwechikamu chepfupi nesimba rezvigadzirwa izvi zvisave zvishoma pane zvaitarisirwa.
Nheyo yekushanda: magetsi anoyerera kubva pakubata kwakasimba 1, anobuda kubva pakubata kwakasimba 2 kuburikidza nekubata kwesirivha kwakasimba uye kubata kwakasimba. Kubata kwacho kunokurumidza kudimburwa nesimba rakasimba remagetsi rekudzora (Holm force uye Lorentz force) kuti kuwedzere kumhanya kwekutyoka.
Dhizaini yemhepo inovhuvhuta: kana mhepo pfupi ikaita large current mudunhu, zvikamu zvinogadzira gasi zvinogadzira imwe gasi pasi pekupisa kwakanyanya kwe arc, kumanikidzwa kwemhepo mubhokisi re contact unit kunowedzera nekukurumidza, uye kuyerera kwemhepo nekukurumidza kunogona kugadzirwa kuburikidza nemhepo inobuda mukamuri re arc extinguishing, iyo inogona kudzima arc zvinobudirira.
