Yintoni i-air circuit breaker kwaye yintoni umsebenzi wayo oyintloko

1. Ukutshintsha umoya
Iswitshi yomoya, eyaziwa ngokuba yii-air circuit breaker, luhlobo lwe-breaker circuit.Lutshintsho lwamandla oluzinqumla ngokuzenzekelayo kuphela xa i-current in circuit idlula i-voltage elinganisiweyo.Ukutshintsha umoya sisixhobo sombane esibaluleke kakhulu kwinethiwekhi yegumbi lokuhambisa kunye nenkqubo yokutsala amandla.Idibanisa ulawulo kunye nokugcinwa kwezinto ezahlukeneyo.Ukongeza kokuchukumisa kunye nokuqhawula umbane wesekethe, kunokubangela iimpazamo ezimfutshane kwisekethe yamandla okanye izixhobo zombane.Umthwalo onzima ngakumbi kunye nokukhuselwa kwe-voltage ngaphantsi kunokusetyenziselwa ukusebenza kwemoto rhoqo.
1. Umgaqo
Xa umgca wokusasaza ugcwele kakhulu, nangona i-overload yangoku ingenakukwazi ukwenza indawo ye-electromagnetic buckle, iya kubangela ukuba i-thermal element ivelise ubushushu obuthile, nto leyo eya kubangela ukuba i-bimetallic sheet igobe phezulu xa ishushu. khulula ikhonkco kunye nokutshixa, ukwaphula umfowunelwa oyintloko, unqumle amandla.Xa isiphaluka esifutshane okanye umsinga womthwalo onzima usenzeka kumgca wokusasaza, umsinga udlula ixabiso elibekiweyo langoku lohambo olukhawulezileyo, kwaye ukukhutshwa kwe-electromagnetic kuvelisa amandla okufunxa okwaneleyo ukutsala i-armature kunye nokubetha i-lever, ukuze i-hook ijikeleze phezulu. ujikeleze isihlalo se-shaft kwaye iqhaga liyakhululwa.Vula, isitshixo siya kuqhawula abafowunelwa abathathu abaphambili phantsi kwesenzo sentwasahlobo yokusabela, kwaye unqumle unikezelo lwamandla.
2. Indima ephambili
Kwiimeko eziqhelekileyo, i-armature yokukhululwa kwe-overcurrent ikhutshwe;kanye xa kuthe kwakho umthwalo onzima okanye isiphene esifutshane, ikhoyili eqhagamshelwe kuthotho kunye nesekethe ephambili iya kuvelisa umtsalane owomeleleyo we-electromagnetic ukutsala i-armature ezantsi kwaye uvule ikhonkco lokutshixa.Vula umfowunelwa oyintloko.Ukukhutshwa kwe-undervoltage kusebenza ngokuchaseneyo.Xa umbane osebenzayo uqhelekile, umtsalane we-electromagnetic utsala i-armature, kwaye unxibelelwano oluphambili lunokuvalwa.Emva kokuba i-voltage yokusebenza iyancipha kakhulu okanye amandla aphelile, i-armature ikhutshwe kwaye oonxibelelwano abakhulu bavulwa.Xa i-voltage yonikezelo lwamandla ibuyela kwisiqhelo, kufuneka iphinde ivalwe ngaphambi kokuba isebenze, eqonda ukukhuselwa kokulahleka kombane.
