Indlela yokukhetha i-air circuit breaker efanelekileyo kuwe

Kwintsimi yobunjineli bombane kunye nokuhanjiswa kwamandla, ukukhetha i-air circuit breaker (ACB) ibaluleke kakhulu. I-air circuit breakers zizinto eziphambili zokukhusela iinkqubo zombane kwi-overloads kunye neesekethe ezimfutshane. Ngeenketho ezininzi ezikhoyo kwimarike, kuquka iimveliso ezivela kubavelisi abahloniphekileyo njengeYuye Electrical Co., Ltd.,kubalulekile ukuqonda iiparamitha eziphambili eziphembelela inkqubo yokhetho. Eli nqaku lijolise ekunikezeni isikhokelo esibanzi sokukunceda ukhethe i-air circuit breaker ehlangabezana nemilinganiselo yakho ethile, ugxininise kuhlobo lomthwalo, i-current circuit current, kunye ne-rated current.

Ukuqonda i-Air Circuit Breakers
Izaphuli zesekethe zomoya zenzelwe ukukhusela iisekethe zombane ngokuphazamisa ukuhamba kwangoku xa kukho impazamo. Basebenzisa umoya njengendawo yokucima i-arc kwaye ifanelekile kwizicelo zombane ophezulu. I-air circuit breakers isetyenziswa ngokuqhelekileyo kwiindawo zoshishino kunye nezorhwebo ukubonelela ngokhuseleko oluthembekileyo lwezixhobo zombane kunye nokuqinisekisa ukhuseleko lwabasebenzi.

Iiparamitha eziphambili zokukhetha
Xa ukhetha i-air circuit breaker, iiparamitha ezininzi kufuneka ziqwalaselwe ukuqinisekisa ukusebenza kakuhle kunye nokuthembeka. Izinto ezintathu eziphambili ezijoliswe kuzo luhlobo lomthwalo, i-short-circuit current, kunye ne-rated current.

1. Uhlobo lomthwalo
Uhlobo lomthwalo owenziwe ngumqhubi wesiphaluka somoya luyingqwalasela ephambili. Imithwalo inokwahlulwa ibe ngamacandelo amathathu: imithwalo yokumelana, imithwalo ye-inductive, kunye nemithwalo ye-capacitive.

Umthwalo oxhathisayo: Uquka izinto zokufudumeza, izibane ze-incandescent, kunye nezinye izixhobo apho umsinga ulingana nombane. Izaphuli zesekethe zomoya kwimithwalo exhathisayo zifuna ukhuseleko oluncinci lwangoku.

Umthwalo we-inductive: Imithwalo ye-inductive ibandakanya ii-motor, ii-transformers, kunye nezinye izixhobo ezenza imimandla yamagnetic. Imithwalo ye-inductive ivelisa i-inrush currents ezinkulu xa iqala, ngokoabaphuli beesekethe zomoyakunye nomthamo ophezulu wokophuka kunye nesetingi ezilungelelanisiweyo ziyafuneka ukujongana nale misinga yokungena.

Imithwalo yeCapacitive: I-Capacitors kunye nezixhobo zokulungiswa kwezinto zamandla ziwela kolu didi. Ii-air circuit breakers (ACBs) zemithwalo ye-capacitive kufuneka zikhethwe ngononophelo njengoko zinokufumana i-inrush currents eziphezulu kwaye zifuna izicwangciso ezithile zokuthintela ukukhubeka kwenkathazo.

Ukuqonda uhlobo lomthwalo kubalulekile ekukhetheni i-ACB eya kuhlangabezana neemfuno zokusebenza ngaphandle kokubeka engozini ukhuseleko okanye ukusebenza.

2. I-short-circuit current
I-short-circuit current ibhekisela kumbane ophezulu onokuhamba kwisekethe phantsi kweemeko eziphosakeleyo. Kubalulekile ukumisela i-current short-circuit current ngexesha lofakelo, njengoko eli xabiso liya kugqiba umthamo ofunekayo wokuphulwa kwe-air circuit breaker.

Ukubala i-short-circuit current, i-impedance iyonke yesiphaluka kufuneka ithathelwe ingqalelo, kubandakanywa i-transformer, i-conductors, kunye nawaphi na amanye amacandelo. Umthamo wokuqhawula we-air circuit breaker kufuneka udlule i-short-circuit current ebalwayo ukuqinisekisa ukuba unokuphazamisa ngokufanelekileyo impazamo kunye nokukhusela izixhobo ezisezantsi.

I-Yuye Electric Co., Ltd. inikezela ngoluhlu lwezaphuli zesekethe zomoya ezinamandla ahlukeneyo okuqhekeka, okuvumela iinjineli ukuba zikhethe imodeli ehlangabezana neemfuno zangoku zesekethe emfutshane yesicelo sabo.

3. Ireyithiwe yangoku
Umlinganiselo olinganisiweyo we-air circuit breaker ubhekisela kubuninzi obuqhubekayo obuqhubekayo ngaphandle kokukhubeka. Le parameter ibalulekile ukuqinisekisa ukuba i-air circuit breaker inokusingatha ukusebenza okuqhelekileyo kwenkqubo yombane.

Xa ukhetha umbane olinganisiweyo, umthwalo opheleleyo odibeneyo kwisiphaluka kufuneka uqwalaselwe. Umjelo olinganisiweyo kufuneka ube phezulu kunomthwalo olindelekileyo olindelekileyo ukukhusela ukuhamba ngokungeyomfuneko ngexesha lokusebenza okuqhelekileyo. Ukongezelela, ekubeni iinkqubo zombane ngokuqhelekileyo zanda ngokuhamba kwexesha, kuyacetyiswa ukuba uqwalasele ukukhula komthwalo wexesha elizayo.

I-Yuye Electric Co., Ltd.inika abaphuli beesekethe zomoya kwiindidi ezahlukeneyo zokulinganiswa kwangoku, okwenza abasebenzisi bakhethe abaqhankqalazi beesekethe abahlangabezana neemfuno zabo zangoku kunye nezexesha elizayo.

Amanye amanqaku
Ngelixa uhlobo lomthwalo, i-short-circuit current kunye ne-rerated current zezona parameters eziphambili zokukhetha i-air circuit breaker, nezinye izinto kufuneka ziqwalaselwe:

Iimeko zokusingqongileyo: Indawo yokufakela inokuchaphazela ukusebenza kwe-air circuit breaker. Xa ukhetha i-breaker circuit, izinto ezifana nobushushu, ukufuma, kunye nokuvezwa kothuli okanye izinto ezidliwayo kufuneka ziqwalaselwe.

Iimpawu zohambo: Izaphuli zesekethe zomoya ezahlukeneyo (ACBs) zineempawu zohambo ezahlukeneyo, kubandakanywa useto lwe-thermal kunye nemagnethi yohambo. Ukuqonda ezi mpawu kubalulekile ukuqinisekisa ukuba i-circuit breaker isebenza ngokufanelekileyo phantsi kweemeko eziphosakeleyo.

Imigangatho kunye neSiqinisekiso: Qinisekisa ukuba i-air circuit breaker ekhethiweyo ihambelana nemigangatho yoshishino efanelekileyo kunye neziqinisekiso. Oku akuqinisekisi kuphela ukhuseleko kunye nokuthembeka, kodwa kuququzelela ukugcinwa kunye nokutshintshwa.

Ukukhetha i-air circuit breaker ibalulekile kwaye inokuchaphazela kakhulu ukhuseleko kunye nokuthembeka kweenkqubo zombane. Ngokuqwalasela ngokucophelela iiparameters ezifana nohlobo lomthwalo, i-short-circuit current, kunye ne-rated current, iinjineli kunye nabaphathi beziko banokukhetha ii-air circuit breakers ezihlangabezana neemfuno zabo ezithile.I-Yuye Electric Co., Ltd. inikezela ngeentlobo ngeentlobo zeenqwelomoya zomoya ezilungiselelwe ukuhlangabezana neemfuno ezahlukeneyo zesicelo, ukuqinisekisa ukuba abasebenzisi banokufumana isisombululo esifanelekileyo kwiimfuno zabo zokukhusela umbane.
