I-circuit breaker:
Kufakwe phakathi kohlangothi olufakiwe lwephakeli yamandla kanye nesiguquli sefrikhwensi.
I-Short circuit breaker: Nqamula amandla lapho izinto ezisebenza ezansi nomfula zidlula umgwaqo ukuze uvimbele izingozi.
I-breaker circuit yokuvikela ukuvuza: isiguquli se-frequency singase sikhiqize i-high-frequency ukuvuza kwamanje lapho sisebenza, ukuze kuvinjwe izingozi zokushaqeka kukagesi futhi kubangele umlilo kagesi, sicela ukhethe i-breaker circuit yokuvikela ukuvuza efanele ngokuvumelana nesimo ensimini.
I-Fuse:
Vimbela izingozi ngenxa yamasekhethi amafushane futhi uvikele amadivaysi e-semiconductor angemuva.
(I-Electromagnetic) Isixhumi:
Ukusebenza kokuphazamisa isiguquli semvamisa, kufanele kugweme ukusebenza kwamandla kaningi akhuphuka naphansi kwesiguquli sefrikhwensi ngokusebenzisa isixhumi esithinta imvamisa (isikhathi sokuphumula asingaphansi kwehora elilodwa) noma ukusebenza okuqondile kokuqala.
I-AC Input Resistor:
Khulisa isici samandla ohlangothini lokokufaka;
Ukuqeda ngempumelelo i-harmonic ephezulu ohlangothini lokokufaka, ukuvimbela ukulimala kwezinye izinto zokusebenza ngenxa yokuhlanekezelwa kwe-voltage waveform; Susa ukungalingani kwamanje okokufaka okubangelwa ukungalingani kwesigaba samandla.
Isihlungi se-EMC:
Yehlisa i-frequency converter conduction yangaphandle kanye nokuphazamiseka kwemisebe; Yehlisa ukuthikamezeka kwe-conductive kusukela ekugcineni kwamandla kuya kusiguquli sefrikhwensi futhi uthuthukise amandla okumelana nokuphazamiseka kwesiguquli sefrikhwensi.
Isihlungi esilula:
Nciphisa ukuqhutshwa kwe-conduct kanye nokuphazanyiswa kwemisebe kusuka ku-inverter.
I-Brake Resistor/I-Brake Resistor:
Injini idla amandla avuselelekayo ngokumelana namabhuleki lapho yehla.
I-DC Resistor:
Khulisa isici samandla ohlangothini lokokufaka;
Thuthukisa ukusebenza kahle kanye nokuzinza kokushisa kwayo yonke i-converter yefrikhwensi;
Susa ngempumelelo umphumela wohlangothi olufakiwe lwe-harmonic ephezulu kusiguquli semvamisa, nciphisa ukuqhutshwa kwangaphandle kanye nokuphazamiseka kwemisebe.
Isiphikisa okukhiphayo:
Uhlangothi oluphumayo lwesiguquli sefrikhwensi ngokuvamile luqukethe ama-harmonics aphezulu kakhulu. Lapho i-motor kanye ne-converter frequency kukude, ngoba kukhona i-capacitor yokusabalalisa enkulu emgqeni. Ngezinye izikhathi
I-Harmonics ingazwakala kusekethe, ilethe imiphumela emibili:
1. Ukulimala ekusebenzeni kwe-motor insulation, kuzolimaza injini isikhathi eside.
2. Khiqiza ukuvuza okukhulu kwamanje, okubangela isiguquli semvamisa ukuvikela njalo.
Ukufaka i-resistor ephumayo kuvikela ukufakwa kwe-motor futhi kunciphisa amandla akhona.
Izindandatho zikaZibuthe namabhande:
Indandatho kazibuthe eseceleni yokokufaka ingacindezela umsindo kusistimu yamandla okufakwayo kwedrayivu. Iringi kazibuthe eseceleni okukhiphayo isetshenziswa kakhulu ukunciphisa ukuphazamiseka kwangaphandle kwedrayivu, nge
Yehlisa i-bearing current.
