Iyini i-air circuit breaker futhi yini umsebenzi wayo oyinhloko

1. Ukushintsha umoya
I-air switch, eyaziwa nangokuthi i-i-air circuit breaker, wuhlobo lwe-circuit breaker.Kuyiswishi yamandla ezinqamula ngokuzenzakalelayo kuphela lapho i-current in circuit idlula i-voltage elinganiselwe.I-air switch iyisisetshenziswa sikagesi esibaluleke kakhulu kunethiwekhi yegumbi lokusabalalisa kanye nesistimu yokudonsa amandla.Ihlanganisa ukulawula kanye nokugcinwa okuhlukahlukene.Ngaphezu kokuthinta nokunqamula isekethe yamandla, kungase futhi kubangele amaphutha esekethe emfishane kumjikelezo wamandla noma okokusebenza kukagesi.Ukugcwala okukhulu kakhulu kanye nokuvikelwa kwe-voltage engaphansi nakho kungasetshenziselwa ukusebenza kwemoto okungajwayelekile.
1. Isimiso
Lapho ulayini wokusabalalisa ngokuvamile ulayishwa ngokweqile, nakuba i-overload yamanje ingakwazi ukwenza indawo yebhande le-electromagnetic buckle, izobangela isici esishisayo ukuthi sikhiqize inani elithile lokushisa, okuzokwenza ukuthi ishidi le-bimetallic ligobe liye phezulu lapho lishiswa, futhi induku yokusunduza izokwenza. khulula ihuku kanye nelokhi, uphule othintana naye oyinhloko, unqamule amandla.Uma isiyingi esifushane noma amandla agcwele kakhulu agcwala kakhulu emugqeni wokusabalalisa, owamanje udlula inani lamanje elimisiwe lohambo olusheshayo, futhi ukukhishwa kukazibuthe kukhiqiza amandla anele okudonsa ukuheha i-armature futhi ishaye i-lever, ukuze ihhuku ijikelezise. eduze kwesihlalo se-shaft futhi ingidi iyakhululwa.Vula, ilokhi izonqamula abathintwayo abathathu abakhulu ngaphansi kwesenzo sentwasahlobo yokusabela, futhi inqamule ukunikezwa kwamandla.
2. Indima eyinhloko
Ngaphansi kwezimo ezijwayelekile, i-armature yokukhululwa kwe-overcurrent iyakhululwa;uma kwenzeka iphutha elikhulu kakhulu noma iphutha le-short-circuit, ikhoyili exhunywe kuchungechunge nesekhethi enkulu izokhiqiza ukukhangwa okunamandla kazibuthe ukuheha i-armature phansi futhi ivule ihhuku yokukhiya.Vula oxhumana naye oyinhloko.Ukukhishwa kwe-undervoltage kusebenza ngokuphambene nalokho.Lapho i-voltage esebenzayo ijwayelekile, ukukhanga kazibuthe kudonsa i-armature, futhi othintana naye oyinhloko angavalwa.Uma i-voltage yokusebenza iyancipha kakhulu noma amandla enqanyuliwe, i-armature iyakhululwa futhi othintana nabo abakhulu bayavulwa.Lapho i-voltage yokunikezwa kwamandla ibuyela kokujwayelekile, kufanele ivalwe kabusha ngaphambi kokuthi isebenze, okuqaphela ukuvikelwa kokulahlekelwa kwamandla kagesi.
