Kusiguquli sefrikhwensi, i-motor fast braking noma ukuma okunembile, ngokuvamile kusetshenziswa i-power braking kanye ne-regenerative braking.Ngemodi yokubopha amandla, i-torque yokubhuleka edingwa uhlelo ingaphansi kuka-20% we-torque elinganiselwe ye-motor futhi i-braking ayisheshi, asikho isidingo sokumelana ne-braking yangaphandle, futhi kuphela ukulahlekelwa okusebenzayo kwangaphakathi kwe-motor can. yenza umkhawulo kagesi oseceleni kwe-DC ube ngaphansi kwevelu yesenzo sokuvikela i-over-voltage.Ngokuphambene nalokho, kuyadingeka ukukhetha i-resistor ye-braking ukuze uchithe le ngxenye yamandla avuselelwe injini.Ukuze ubone ukubhuleka kukagesi, uhlangothi lwe-DC lwe-inverter kufanele lufakwe isekethe yokuthola i-voltage ukuze kutholwe i-voltage ye-capacitor ukuze kubonakale ukubhuleka kwamandla.Amabhuleki resistorsasetshenziswa kabanzi emikhiqizweni ehlukahlukene ye-elekthronikhi.
Lapho ubhuleka nge-resistor yangaphandle ye-braking, i-resistor yangaphandle kufanele ikwazi ukumunca u-80% wamandla kagesi aguqulwa amandla angaba namandla, okuthi ama-20% awo angadliwa nge-motor ngendlela yokushisa ukushisa, ngalesi sikhathi inani. of the resistor braking iba ezincane, kungakhathaliseki motor ngokuphindaphindiwe decelerated, ukukhethwai-braking resistoramandla alinganisiwe ahlukile.Uma ukwehla okungaphindiwe, isixhasi sokubhuleka sesikhathi esimaphakathi (T-tS) > 600s.Ngokuvamile sebenzisa i-resistor duty resistor, lapho ukubhuleka ngezikhathi ezithile, amandla avumelekile we-resistor azokwandisa ukusetshenziswa kokukhethwa okulungile kwe-braking unit resistor kunganciphisa isikhathi sokumisa samahhala semithwalo ye-inertia enkulu ukuze kuzuzwe ukuma ngokushesha noma ukuma okunembile;kungase futhi kube in the bit amandla imithwalo yehliswa ukuze kuzuzwe operation regenerative.
Amanye amakhasimende 'i-electrolysis workshop multifunctional unit design ayizange icabange ukwengeza i-inverteri-braking resistor, okuholela ekumiseni isikhathi eside samahhala kanye nebanga elide lokushushuluza imoto enkulu, ekhona ingozi efihliwe yokukhiqiza nokusebenza;Kunzima ukubona ukuma okunembile kwezinqola zamathuluzi nama-aluminium trolleys, okuthinta ukusebenza kahle komsebenzi.Ngemuva kokufakwa kwe-braking resistors, izinkinga ezingenhla ziyaxazululwa.Kodwa-ke, kufanele kuqashelwe ukuthi, ekukhethweni kwe-resistor braking, hhayi kuphela ukucabangela izidingo zokukhethwa komkhiqizi we-inverter braking resistor, kodwa futhi ngokuvumelana nezidingo zokulawula komsebenzisi kanye nokusetshenziswa kwezindawo ezahlukene, kufanele kube ngesivinini. , i-torque nezinye izilinganiso, bese kubala ukukhetha okulungile kwe-resistor yokubhuleka, ukuze kuzuzwe izimfuneko zokulawula zomsebenzisi.
