I-low-voltage frame breaker type breaker, ikwisixhobo esisisiseko sokusasaza, sisixhobo esikhulu esine-low-voltage circuit breaker, esinomthamo ophezulu wokuqhawula i-short-circuit kunye nokuzinza okuphezulu okuguquguqukayo, iimpawu zokukhusela izigaba ezininzi, ezisetyenziswa ikakhulu kwi-10kV/380V. i-transformer yamandla ye-380V icala, esetyenziselwa ukuhambisa amandla kunye nokukhusela imigca kunye nezixhobo zamandla, Ngokugqithiswa, isiphaluka esifutshane, phantsi kombane, ukusekwa kwesigaba esisodwa kunye neminye imisebenzi yokukhusela impazamo kunye nomsebenzi wokuzihlukanisa.Iqokobhe eliphantsi kwe-voltage yeshekethi yeshekethi ephantsi yomgangatho weqondo langoku ngokubanzi yi-200A ~ 6300A, umthamo wokwaphulwa kwesekethe emfutshane yi-40 ~ 50kA, kunye neendlela ezintathu zokusebenza zemanuwali, i-lever kunye nombane, umda womthamo ophezulu woku-off we-universal circuit breaker sebenzisa. indlela yokusebenza yokugcina amandla ukuphucula isantya sokuvala.I-universal low-voltage circuit breaker ikakhulu iqulunqwe yinkqubo yoqhagamshelwano, indlela yokusebenza, isixhobo sokukhupha i-over-current, i-shunt release device kunye nesixhobo sokukhululwa esingaphantsi kwe-voltage, izixhobo, isakhelo, i-wiring circuit circuit kunye nezinye iindawo.Zonke iinqununu zifakwe kwi-insulated kwaye zifakwe kwisiseko sentsimbi yesakhelo se-insulation liner.Izixhobo ezahlukeneyo zokukhulula kunye nezixhobo zinokudibaniswa ukuze zenze i-circuit breakers kunye neempawu ezikhethiweyo, ezingakhethiyo okanye ezichasene nexesha lokusebenza.Ulawulo olukude lunokwenzeka ngokusebenzisa oonxibelelwano abancedisayo.Kukho iintlobo ezininzi kunye neemodeli ze-universal low-voltage circuit breakers, iibrendi ezininzi, kunye nokusebenza okwahlukileyo.Ngaphantsi kweemeko eziqhelekileyo, ingasetyenziselwa ukuguqulwa okungaqhelekanga komgca.
Iqokobhe leplastiki uhlobo lwesaphuli sesekethe esine-voltage ephantsi (esibizwa njengeplastiki-imeko yohlobo lwesaphuli sesekethe esinevoltage ephantsi) yeyesixhobo sombane sosasazo lwesibini.Ibonakaliswa ngeentlobo ngeentlobo zezixhobo ezinokudityaniswa kwimisebenzi eyahlukeneyo ye-breaker circuit, isakhiwo esisisiseko senziwe nge-insulation evaliweyo iqokobhe (ezinye iimveliso ziseqokobheni elicacileyo), indlela yokusebenza, uqhagamshelwano kunye nenkqubo yokucima i-arc, ukukhululwa kwemagneti kunye nezixhobo. 5 amacandelo asisiseko.Amacandelo asisiseko aquka isixhobo sokukhulula samahhala, isixhobo sokukhulula i-thermal, uqhagamshelwano oluphambili, iqhosha lokuvavanya, isango lokucima i-arc kunye nendlela yokusebenza.Izincedisi ezahlukeneyo zinokukhethwa ngokweemfuno ukuhlangabezana neemfuno ezahlukeneyo zokusebenza.
Izaphuli zesekethe ezincinci, ezikwabizwa ngokuba ziimodyuli ezincinci zesekethe, zisetyenziswa ngokubanzi kwiibhokisi zokuhambisa amandla ekupheleni kwemigca yokuhambisa i-terminal, iibhokisi zokuhambisa izibane kunye nezinye iiseti ezipheleleyo zeebhokisi zombane, zokuhambisa imigca, iimoto, iisekethe zokukhanyisa kunye nezinye izixhobo zombane. ukusabalalisa, ukulawula kunye nokukhusela (isiphaluka esifutshane, ukugqithiswa, ukuvuza).I-micro circuit breaker iqulethe i-handle operating mechanism, i-thermal release device, i-electromagnetic release release, i-contact system, i-arc interrupter kunye nezinye izinto, zonke ezibekwe kwi-insulating house.Iimpawu zesakhiwo zibukhulu benkcazo yemodyuli (ubuninzi be-9mm) kunye nomzila wofakelo, ububanzi bemodyuli ye-single-pole (1P) i-breaker circuit ye-high-current product yi-18mm (27mm), ububanzi bomnye- ipali (1P) isaphuli sesekethe yemveliso encinci-yangoku yi-17.7mm, ukuphakama kwentamo yeconvex yi-45mm, kwaye ukufakela kusebenzisa isiporo esiqhelekileyo se-35mm.I-slot yokufakela emva kwe-breaker circuit kunye ne-clamping clip ene-spring isetyenziselwa ukubeka kunye nokulula ukuchithwa.Kukho i-unipolar + neutral (uhlobo lwe-1P + N), i-unipolar (1P), ezimbini (2P), ezintathu (3P) kunye neentlobo ezine (4P).
