Uma ukhetha i-air circuit breaker, izinkomba zobuchwepheshe eziyinhloko okufanele zihlolwe

Lapho uklama futhi ukhetha ama-air circuit breaker, izinkomba zobuchwepheshe eziyinhloko okufanele zihlolwe yilezi ezilandelayo. Lezi zinkomba zobuchwepheshe zidlala indima ebalulekile ekuqinisekiseni ukuphepha nokusebenza kahle kohlelo lukagesi lapho kufakwa khona ama-air circuit breaker.

Okokuqala, isilinganiso se-voltage ye-voltagei-air circuit breakerkuyinto ebalulekile okufanele icatshangelwe.I-ACBkufanele ihambisane nezidingo ze-voltage zesistimu kagesi. Ububanzi be-voltage obulinganiselwe buyi-AC200 kuya ku-690V kanye ne-DC250 kuya ku-400V, ngakho-ke i-voltage elinganiselwe ye-air circuit breaker kumele ifane ne-voltage yesistimu.

Esinye isibonakaliso esibalulekile sobuchwepheshe yi-current rated (Inm) yohlaka lwe-low-voltage circuit breaker. Izinhlobo ezahlukene zomkhiqizo zinamazinga ahlukene wamanje alinganisiwe futhi kubalulekile ukubukeza ngokucophelela ulwazi lobuchwepheshe lomkhiqizo ukuqinisekisa ukuthi luhlangabezana nezidingo zesistimu kagesi.

Isilinganiso samanje (In) se-low voltage circuit breaker naso siyinto ebalulekile okufanele icatshangelwe. Ukukhetha kufanele kusekelwe kumthamo we-transformer oklanyelwe (kV·A) kanye nokuhlaziywa okuningiliziwe kwedatha yobuchwepheshe yomkhiqizo odingekayo.

Umthamo wokuphuka kokusebenza olinganiselwe (Ics) uyinkomba ebalulekile yokusebenza kanye nokuthembeka kwe-air circuit breaker. Kubalulekile ukukhetha umkhiqizo onomthamo wokuphuka ofanele ngokusekelwe emazingeni omthwalo, uhlobo lokwakha kanye nokucatshangelwa kwezezimali.

Ngaphezu kwalokho, umthamo wokuphuka olinganiselwe (Icu), umthamo wokuma olinganiselwe wesikhathi esifushane (Icw), inani lezinsika, njll. konke kuyizinkomba zobuchwepheshe ezibalulekile okufanele zihlolwe lapho kukhethwa i-air circuit breaker.

Uma ubuyekeza lezi zincazelo, kubalulekile ukucabangela izidingo kanye nezici ezithile zesistimu kagesi lapho kufakwa khona i-air circuit breaker. Ngokuhlola ngokucophelela lezi zincazelo, i-air circuit breaker ingakhethwa ukuze ivumelane nezidingo zesistimu yakho kagesi, iqinisekise ukuphepha, ukuthembeka kanye nokusebenza kahle.
