Indlela yokukhetha i-air circuit breaker efanele kuwe

Emkhakheni wobunjiniyela bakagesi nokusatshalaliswa kwamandla, ukukhetha i-air circuit breaker (ACB) ibaluleke kakhulu. Ama-air circuit breaker ayizingxenye ezibalulekile zokuvikela amasistimu kagesi ekulayishweni ngokweqile kanye namasekethe amafushane. Ngezinketho eziningi ezitholakalayo emakethe, okuhlanganisa imikhiqizo evela kubakhiqizi abahloniphekile njengeI-Yuye Electrical Co., Ltd.,kubalulekile ukuqonda amapharamitha abalulekile athonya inqubo yokukhetha. Lesi sihloko sihlose ukuhlinzeka ngomhlahlandlela ophelele wokukusiza ukuthi ukhethe i-air circuit breaker ehlangabezana nemibandela yakho ethile, egxile ohlotsheni lomthwalo, i- short circuit current, kanye nesilinganiso samanje.

Ukuqonda ama-Air Circuit Breakers
Ama-air circuit breaker aklanyelwe ukuvikela amasekhethi kagesi ngokuphazamisa ukuhamba kwamandla lapho kwenzeka iphutha. Basebenzisa umoya njengesici sokucisha i-arc futhi bafanele ukusetshenziswa kwamandla kagesi aphezulu. Ama-air circuit breaker avame ukusetshenziswa ezimweni zezimboni nezentengiso ukuze anikeze ukuvikeleka okuthembekile kwemishini kagesi nokuqinisekisa ukuphepha kwabasebenzi.

Amapharamitha angukhiye wokukhetha
Lapho ukhetha i-air circuit breaker, imingcele eminingi kufanele icatshangelwe ukuze kuqinisekiswe ukusebenza kahle nokuthembeka. Izinto ezintathu eziyinhloko okufanele kugxilwe kuzo uhlobo lomthwalo, wamanje wesifunda esifushane, kanye nesilinganiso samanje.

1. Uhlobo lomthwalo
Uhlobo lomthwalo olusetshenziswa yi-air circuit breaker luwukucatshangelwa okubalulekile. Imithwalo ingahlukaniswa ngezigaba ezintathu: imithwalo ephikisanayo, imithwalo ye-inductive, nemithwalo ye-capacitive.

Umthwalo ovimbelayo: Kuhlanganisa izinto zokushisisa, amalambu e-incandescent, nezinye izisetshenziswa lapho zamanje zilingana ne-voltage. Ama-air circuit breaker wemithwalo ephikisanayo ngokuvamile adinga ukuvikelwa kwamanje okuncane.

Umthwalo ongenisayo: Imithwalo engenisayo ihlanganisa amamotho, ama-transformer, namanye amadivaysi akhiqiza izinkambu kazibuthe. Imithwalo ye-inductive ikhiqiza ama-inrush currents amakhulu lapho iqala, ngakhoama-air circuit breakersenekhono eliphezulu lokuphuka kanye nezilungiselelo ezilungisekayo ziyadingeka ukuze kusingathwe lawa magagasi okuhlasela.

Imithwalo ye-capacitive: Ama-Capacitor namadivayisi okulungisa isici samandla awela kulesi sigaba. Ama-air circuit breaker (ACBs) wemithwalo enamandla kufanele akhethwe ngokucophelela njengoba angase abe nama-inrush currents aphezulu futhi adinga izilungiselelo ezithile ukuze avimbele ukukhubeka kwenkathazo.

Ukuqonda uhlobo lomthwalo kubalulekile ekukhetheni i-ACB ezohlangabezana nezidingo zokusebenza ngaphandle kokuphazamisa ukuphepha noma ukusebenza.

2. I-Short-circuit current
I-short-circuit current ibhekisela kumthamo wamanje omkhulu ongageleza kusekethe ngaphansi kwezimo zephutha. Kubalulekile ukunquma i-current short-circuit current ngesikhathi sokufakwa, njengoba leli nani lizonquma umthamo odingekayo wokuphuka we-air circuit breaker.

Ukuze ubale i-current-circuit current, i-impedance ephelele yesifunda kufanele icatshangelwe, kuhlanganise ne-transformer, abaqhubi, kanye nanoma yiziphi ezinye izingxenye. Amandla okuphuka kwesiphazamisi somoya kufanele adlule umthamo wamanje wesekethe emfishane ebaliwe ukuze kuqinisekiswe ukuthi ingaphazamisa ngempumelelo iphutha futhi ivikele izinto ezisetshenziswayo ezansi nomfula.

I-Yuye Electric Co., Ltd. inikezela ngezinhlobonhlobo zama-air circuit breaker anamandla ahlukene okuphuka, okuvumela onjiniyela ukuthi bakhethe imodeli ehlangabezana nezidingo zamanje ze-short-circuit yesicelo sabo.

3. Ikalwe okwamanje
Isilinganiso samanje se-air circuit breaker sisho umkhawulo wamanje oqhubekayo ongawuthwala ngaphandle kokukhubeka. Le parameter ibalulekile ukuze kuqinisekiswe ukuthi i-air circuit breaker ingakwazi ukuphatha ukusebenza okuvamile kwesistimu kagesi.

Lapho ukhetha i-current elinganisiwe, umthwalo ophelele oxhunywe kumjikelezo kufanele ucatshangelwe. Isilinganiso samanje kufanele sibe phezulu kunomthwalo omkhulu olindelwe ukuvimbela ukukhubeka okungadingekile phakathi nokusebenza okuvamile. Ngaphezu kwalokho, njengoba amasistimu kagesi ngokuvamile akhula ngokuhamba kwesikhathi, kunconywa ukucabangela ukukhula komthwalo wesikhathi esizayo.

Inkampani Yuye Electric Co., Ltd.inikeza ama-circuit breaker ngezilinganiso ezihlukahlukene zamanje, okuvumela abasebenzisi ukuthi bakhethe ama-circuit breaker ahlangabezana nezidingo zabo zokulayisha zamanje nezesikhathi esizayo.

Amanye Amanothi
Ngenkathi uhlobo lomthwalo, wamanje wesiyingi esifushane kanye nesilinganiso samanje kuyimingcele eyinhloko yokukhetha i-air circuit breaker, ezinye izici kufanele zicatshangelwe:

Izimo zemvelo: Indawo yokufaka ingathinta ukusebenza kwe-air circuit breaker. Lapho kukhethwa i-circuit breaker, izici ezifana nezinga lokushisa, umswakama, nokuchayeka othulini noma izinto ezonakalisayo kufanele zicatshangelwe.

Izimpawu Zohambo: Izinqamuli zomoya ezihlukene (ama-ACB) zinezici zohambo ezihlukile, ezifaka izilungiselelo zohambo olushisayo nokazibuthe. Ukuqonda lezi zici kubalulekile ukuqinisekisa ukuthi i-circuit breaker isebenza ngokuphumelelayo ngaphansi kwezimo zephutha.

Amazinga kanye Nesitifiketi: Qiniseka ukuthi i-air circuit breaker ithobelana namazinga afanele embonini kanye nezitifiketi. Lokhu akugcini nje ngokuqinisekisa ukuphepha nokwethembeka, kodwa futhi kusiza ukugcinwa nokushintshwa.

Ukukhetha i-air circuit breaker efanele kubalulekile futhi kungaba nomthelela omkhulu ekuphepheni nasekuthembekeni kwezinhlelo zikagesi. Ngokucabangela ngokucophelela amapharamitha afana nohlobo lomthwalo, i-short-circuit current, kanye nesilinganiso samanje, onjiniyela nabaphathi besikhungo bangakhetha ama-air circuit breaker ahlangabezana nezidingo zabo ezithile.Inkampani Yuye Electric Co., Ltd. inikeza ama-air circuit breaker anhlobonhlobo aklanyelwe ukuhlangabezana nezidingo ezihlukahlukene zohlelo lokusebenza, ukuqinisekisa ukuthi abasebenzisi bangathola isixazululo esiphelele sezidingo zabo zokuvikela ugesi. Ngokulandela imihlahlandlela echazwe kulesi sihloko, ungenza isinqumo unolwazi futhi uthuthukise ukuphepha nokusebenza kahle kokufaka kwakho ugesi.
