izimo zokusetshenziswa kwe-air circuit breaker (ACB)

Ezweni lezinhlelo zikagesi kanye nokusatshalaliswa kwamandla, ukuqinisekisa ukuphepha nokuvikelwa kwemishini kubalulekile. Yilapho i-air circuit breaker eguquguqukayo nethembekile (I-ACB, i-air circuit breaker) iyasetshenziswa. I-ACB ikhiqizwa yiMutai Electric Group, i-umenzi we-air circuit breakeruneminyaka eminingi yesipiliyoni ku-R&D, ukukhiqiza kanye nokuthengisa. Isetshenziswa kabanzi emikhakheni yama-voltage aphansi, ama-voltage aphakathi kanye nama-voltage aphansi. Uhlelo lokusabalalisa amandla e-voltage ephezulu kanye nokuhlolwa komkhiqizo wamandla.

Kuzinhlelo zokusatshalaliswa kwamandla aphansi, ama-circuit breaker ajwayelekile adlala indima ebalulekile ekuvikeleni imishini ebalulekile efana nama-generator, ama-transformer kanye nama-motor kuma-short circuits, ama-overload kanye nama-undervoltage. I-ACB ayiqinisekisi nje kuphela ukuphepha kwalawa madivayisi, kodwa futhi ivumela ukulawula okukude kanye nokuqapha ama-circuits aphansi. Ngokuhlinzeka ngokuthembeka okuthuthukisiwe kokusebenza kanye nokuphepha, i-ACB isiza ekuvimbeleni ukulimala kwemishini ebalulekile futhi iqinisekise ukusebenza kohlelo okungaphazanyiswa.

Ama-air circuit breaker asebenza kahle kakhulu futhi asetshenziswa kabanzi ezinhlelweni zokusabalalisa i-medium voltage. Ahlinzeka ngokuvikelwa okuqinile kwemishini efana nama-busbar e-medium-voltage, ama-distribution transformer, kanye nama-conductor angenayo naphumayo. Njengezinhlelo ze-low voltage, ama-ACB ahlinzeka ngokulula kokuqapha okude, anciphisa izindleko zokuphathwa kwabasebenzi, futhi athuthukise ukusebenza kahle kwesistimu iyonke.

Ezinhlelweni zokusatshalaliswa kwamandla kagesi aphezulu, i-ACB isebenza ngokubambisana nezinye izingxenye zikagesi ukuvikela izingxenye ezibalulekile njenge-switchgear enamandla kagesi aphezulu, ama-circuit breaker, izintambo kanye nemigqa ephezulu. Ngokubona nokusabela ngempumelelo emaphutheni, ama-ACB afakwe kufreyimu aqinisekisa ukusebenza okuphephile kwalezi zingxenye ezibalulekile, ngaleyo ndlela anciphise isikhathi sokungasebenzi futhi anciphise ingozi yomonakalo. Ngaphezu kwalokho, i-ACB ingaphinde iqaphe futhi ilawule kude igridi yamandla kagesi aphezulu, ithuthukise ukuthembeka nokusebenza kahle kohlelo.

Ngaphezu kwezinhlelo zokusatshalaliswa kwamandla, ama-air circuit breaker nawo asetshenziswa ekuhlolweni kwemikhiqizo yamandla. Izinkampani zokukhiqiza, ikakhulukazi lezo ezisebenza ngama-inverter, imishini ye-UPS kanye neminye imishini kagesi, zingathembela kuma-ACB afakwe kufreyimu ukuze kutholakale amaphutha ngokunembile. Amandla ayo azenzakalelayo kakhulu asheshe abone noma yimaphi amaphutha kagesi, okuqinisekisa ukuthi amabhizinisi aletha imikhiqizo kagesi esezingeni eliphezulu kumakhasimende awo.

Iqembu Likagesi LaseMutaiingumkhiqizi ohamba phambili we-ACB kanye nomkhiqizi we-air circuit breaker onethonya elikhulu embonini, enezinkampani ezingaphezu kweshumi nambili ezigxile kuma-circuit breaker, ama-contactor, ama-dual power automatic transfer switches kanye neminye imikhakha ehlobene. Njengoba ineminyaka eminingi yesipiliyoni ku-R&D, ukukhiqiza kanye nokuthengisa, iQembu selibe ngumhlinzeki othembekile wezingxenye zikagesi zesigaba sokuqala kanye nezixazululo.

Ngamafuphi, ama-air circuit breaker (ACB) anikeza izinhlelo zokusebenza eziningi ezinhlelweni ezahlukene zokusatshalaliswa kwamandla kanye nokuhlolwa komkhiqizo wamandla. Le divayisi esebenza ngezindlela eziningi iqinisekisa ukuphepha nokuvikelwa kwemishini ngenkathi ivumela amandla okulawula kude nokuqapha. Kungakhathaliseki ukuthi yi-voltage ephansi, i-voltage ephakathi, izinhlelo zokusatshalaliswa kwamandla aphezulu, noma ukuhlolwa komkhiqizo wamandla, i-ACB ibonakale iyingxenye ebalulekile yokukhulisa ukuthembeka kokusebenza, ukuphepha kanye nokusebenza kahle.
