The miniature circuit breaker

Iyo Miniature Circuit Breaker inozivikanwawo seMicro Circuit Breaker, inokodzera AC 50/60Hz yakayerwa voltage 230/400V, yakayerwa ikozvino kusvika ku63A dunhu kuwandisa uye kupfupika kwekudzivirira kwedunhu.Inogonawo kushandiswa sechinhu chisingawanzoitiki chekushandura mutsara pasi pemamiriro ezvinhu.Madiki edunhu mabreak anonyanya kushandiswa mumaindasitiri, ekutengeserana, epamusoro-kukwira uye ekugara nedzimwe nzvimbo.Chigadzirwa chacho chinofanira kuenderana neIEC60898 zviyero.

Mamiriro ekushanda:

1) Muganho wepamusoro wekukosha kwekushisa kwemhepo haifaniri kudarika +40 ° C, iyo yakaderera muganho kukosha haizove yakaderera pane -5 ° C, uye avhareji tembiricha kukosha kwe24h haifaniri kudarika +35 ° C;

Cherechedzo 1: Muganho wakaderera ndeye -10 ℃ kana -25 ℃ mamiriro ekushanda, mushandisi anofanira kuzivisa kumugadziri kana achiraira;

Cherechedzo 2: Kana muganho wepamusoro ukapfuura +40 ° C kana muganho wepasi wakadzikira pane -25 ° C, mushandisi anotaurirana nemugadziri.

2) Kukwirira kwenzvimbo yekuisa hakupfuuri 2000m;

Hunyoro hwemuchadenga haupfuuri 50% kana tembiricha yemhepo yakadzika iri +40 ° C, uye kukosha kwepamusoro kweiyo tembiricha yemhepo inogona kubvumidzwa kuve nehunyoro hwepamusoro pane tembiricha yakaderera isingapfuure +40 ° C, iyo yakaderera muganho kukosha haisi pasi pe -5 ° C, uye avhareji tembiricha kukosha kwe24h haipfuuri +35 ° C;Semuenzaniso, kusvika ku90% pa +20 ° C, matanho akakodzera anofanirwa kutorwa kuitira kugadzirisa nguva nenguva kunokonzerwa nekushanduka kwekushisa;

4), mwero wekusvibisa :2;

5), chikamu chekuisa: Kirasi II uye Kirasi III;

6) Iyo yekunze magineti yenzvimbo yekuisa haifanirwe kudarika 5 nguva yegeomagnetic munda mune chero nzira;

7), kuisirwa kwakaringana kwakamira, chero nzira yekushivirira 2 °;

8) Hapafanirwe kuve nekukanganisa kwakakosha uye vibration pakuiswa.

Iyo miniature circuit breaker ine hunhu hwechimiro chepamberi, kuita kwakavimbika, kugona kutyora kwakasimba, kunaka uye kudiki kutaridzika, etc. Inonyanya kushandiswa panzvimbo iyo AC iri 50HZ kana 60HZ, iyo yakatemerwa voltage iri pazasi 400V uye yakatarwa kushanda. ikozvino iri pasi pe63A.Inoshandiswa pakuremerwa uye kupfupika kwedunhu kudzivirira kwemwenje, mitsara yekugovera uye midziyo yezvivakwa zvehofisi, zvivako zvekugara uye zvivakwa zvakafanana, uye inogonawo kushandiswa kune zvisingaite pa-off kushanda uye kutendeuka kwemitsara.Inonyanya kushandiswa mumaindasitiri, kutengeserana, yakakwirira-kukwira uye yekugara nedzimwe nzvimbo.

Paunenge uchipeta iyo inowanzo shandiswa mini-circuit breaker kuti iparadze dunhu, iyo inofamba yekubata kweiyo mini-circuit breaker inoparadzaniswa kubva kune yakagadziriswa yekubata nemuchina nzira.Kana iyo switch yakavharwa, iyo yakatarisana ne mechanical motion inoshandiswa kuvhara iyo inofamba inosangana uye yakagadziriswa kusangana.Kana dunhu remutoro richibatidzwa nekudzimwa, arc ichaitika pakati peiyo yakagadziriswa yekubata uye inofamba yekubata.Iyo arc inogadzirwa nekupwanya maitiro yakanyanya kukomba pane yekuvhara maitiro.Kana iyo yekutyora ikozvino yakakura kwazvo, kunyanya kana iyo pfupi yedunhu yakaputsika, iyo arc yakakura kwazvo, uye kazhinji yakaoma kwazvo kubvisa dunhu.
