Nguwuphi umahluko phakathi kwee-breakers zesekethe ezincinci kunye ne-molded case circuit breakers

Umqhekezi wesekethe omncinci(emva koku kubhekiselwa kuyo njenge-MCB) yimveliso yokutshintsha i-circuit breaker enoluhlu olukhulu lokusetyenziswa kunye nenani elikhulu.Umsebenzi wayo oyintloko kukugcina izixhobo zokuhambisa amandla kwi-terminal engineering engineering.Kuba zombini ziyinxalenye yokutshintsha okukodwa, iiplastic case circuit breakers zifaneleka ubukhulu becala kwiibhutsi ezinomthamo omncinci, ngoko ke kuyasebenza kakhulu kwaye kubalulekile ukuqonda umahluko phakathi kwezi zimbini kwaye ukhethe into eyiyo.Indima ephambili yeiplastiki ityala lesekethe umaphuli(emva koku kubhekiselwa kuyo njenge-MCCB) kukugcina iziphene zomthwalo kunye neesekethe ezimfutshane kwiinkqubo zokuhambisa amandla ombane ophantsi kunye neesekethe zokulawula ukhuseleko lweemoto.Sele iyinto eqhelekileyo kwishishini ngenxa yokhuseleko nokuthembeka kwayo.Nantsi inkcazelo emfutshane.
Okokuqala, makhe sithethe ngezinto ezisisiseko eziqhelekileyo.Ekubeni zombini i-switch switch, enye imigangatho yokuphunyezwa kwemveliso kufuneka ilandelwe, kwaye imigaqo iyafana.Emva koko thetha ngomahluko phakathi kwezi zinto zimbini.Ngokuqhelekileyo, kukho le miba ilandelayo:
1. Iiparamitha eziphambili zezixhobo zombane zihluke.
2. Iiparamitha eziphambili zezixhobo zoomatshini zihluke.
3. Ukusetyenziswa kwendawo yeofisi kwahlukile.
Kwakhona, ngokwembono yokuthenga, kukho umahluko omkhulu phakathi kwezi zimbini.
Inqanaba langoku
Elona nqanaba liphezulu langoku leiplastiki ityala lesekethe umaphuliyi 2000A.Elona nqanaba liphezulu langoku lei-breaker circuit encinciingaphakathi kwe-125A.Ngenxa yomahluko kumthamo, kumsebenzi wokwenyani, indawo esebenzayo yeplastiki yesaphuli sesekethe iphinda idlule leyo yesaphuli sesekethe esincinci.Ngexesha elifanayo, iingcingo ezidibeneyo nazo zikhulu kakhulu, ezinokufikelela ngaphezu kwe-35 square metres, ngelixa i-breaker circuit miniature ifanelekile kuphela ukudibanisa imigca yokuhambisa ngaphakathi kweemitha ezili-square ezili-10.Ngoko ke, ngokubanzi, amagumbi amakhulu afaneleka ngakumbi ekukhetheni i-plastic case circuit breakers, kuxhomekeke kwimeko yegumbi.
Indlela yokufakela
I-Plastiki ye-circuit breakers idityaniswe ikakhulu kunye nezikrufu, ekulula kakhulu ukuxinga, zinonxibelelwano oluhle kwaye ziqhube kakuhle.Izaphuli zesekethe ezincinci zixhonywa ikakhulu kwiireyile, ngamanye amaxesha zikhokelela ekudibaneni kakubi ngenxa yetorque engonelanga.Ngenxa yeendlela ezahlukeneyo zokufakela, ukudityaniswa kwee-breakers zeplastiki zecala lomelele kwaye lincinci kunee-breakers zesekethe ezincinci.
Owona msebenzi kunye nobomi benkonzo.
ekusebenzeni ngokwenyani.I-molded case circuit breakers ikhuselwe iiseti ezimbini zezixhobo ze-overcurrent kunye ne-short circuit ngokulandelanayo.Ixabiso lesenzo sokukhuselwa kwe-overcurrent lingalungiswa ngesandla, elilungele kwaye likhawuleza.Ukuhamba okuchasayo kunye nephutha le-short-circuit ye-micro-circuit breaker sebenzisa isethi efanayo yezixhobo, kwaye okwangoku akukwazi ukulungiswa, okuhlala kunzima ukuyicombulula.I-molded case circuit breaker inomgama omkhulu we-interphase kunye ne-arc yokucima isiciko, esinamandla okucima i-arc eqinile, inokumelana nomthamo wesiphaluka esifutshane, akukho lula ukubangela i-interphase short circuit, kwaye inobomi obude benkonzo kune-micro circuit breakers.
Sebenzisa izakhono zokulungelelanisa.
Ngakolunye uhlangothi, i-plastic case circuit breakers ivelele ngakumbi, kwaye isakhono sabo sokulungelelaniswa kweseti yomelele kuneso saphuli sesekethe esincinci.Izixhobo zokukhusela ezigqithisileyo kunye ne-overcurrent ye-plastic case circuit breaker zihlukaniswe omnye komnye, kwaye ixabiso lesenzo sokukhusela ngokugqithisileyo liyakwazi ukulungiswa ngokuguquguqukayo.Ukukhuselwa kwexesha elifutshane kunye nokukhuselwa kwangoku kwe-micro-circuit breaker zixhobo ezidibeneyo, kwaye ukulungelelanisa kunye nokukwazi ukulungelelanisa akwanele.
Ngokusekwe koku ngasentla, kubonakala ngathi zonke ii-MCBs zikwimeko engalunganga, kodwa enyanisweni, kwezinye iimeko, ii-MCBs kufuneka zikhethwe.Ngokomzekelo, xa ukhuseleko lwendlela kufuneka luphuculwe, ngenxa yesimo esiphezulu sovakalelo lwe-breaker circuit breaker, isenzo sokuqhawula sikhawuleza, esilungele ngakumbi ukugcinwa kwendlela kunye nezixhobo zendlu.
Ngoko ke, sinokubona ukuba zombini zineenzuzo ezahlukeneyo kunye neendawo zesicelo.Kubalulekile ukuqonda ngokupheleleyo umahluko phakathi kweeplastic case circuit breakers and miniature circuit breakers kwaye ukhethe ngokweemfuno zakho.
