I-frequency converter – okanye i-variable frequency drive (VFD) – sisixhobo sombane esiguqula umbane onomlinganiselo othile ube ngumbane onomlinganiselo omnye. I-voltage idla ngokufana ngaphambi nasemva kokuguqulwa komlinganiselo. Ii-frequency converters zihlala zisetyenziselwa ukulawula isantya seemoto ezisetyenziselwa ukuqhuba iipompo kunye neefeni.
I-frequency converter sisixhobo sombane esiguqula umbane onomlinganiselo othile ube ngumbane onomlinganiselo omnye. I-voltage idla ngokufana ngaphambi nasemva kokuguqulwa komlinganiselo. Ii-frequency converters zihlala zisetyenziselwa ukulawula isantya seenjini ezisetyenziselwa ukuqhuba iipompo kunye neefeni.
Umzekelo olandelayo ubonisa indlela esebenza ngayo le nto:
Ifeni inikwa umbane we-400 VAC, 50 Hz. Kule frequency (50 Hz), ifeni ingasebenza ngesantya esithile. Ukuze ifeni isebenze ngokukhawuleza, kusetyenziswa isixhobo sokuguqula amaza ombane ukwandisa amaza ombane ukuya (umzekelo) kwi-70 Hz. Okanye, amaza ombane angaguqulwa abe yi-40 Hz ukuba ifeni ifuna ukusebenza kancinci.
Awufuni ukufaka izixhobo kumthombo wamandla ongalunganga okanye usengozini yokuvumela umsi ukuba uphume kwizixhobo zakho. Kwaye umsi ufana "ne-genie ebhotileni", xa uphuma kwisixhobo se-elektroniki, awunakuyibuyisela kwi ... Izixhobo ezinkulu nezinezigaba ezi-3 azikwazi ukusebenza kwi-frequency engalunganga njengoko i-frequency engalunganga inokubangela umonakalo okanye ukuguguleka kwangaphambi kwexesha kwizixhobo.
Ke ngoko, indlela yokwahlula i-frequency converter yokwenyani esetyenziswa kumatshini wokuhlamba iimoto eya kuba yinjongo ephambili.
Enyanisweni, phantse abathengisi bathi bane-converter kwaye bayifaka kumatshini wokuhlamba iimoto. Kodwa ayisiyo-frequency converter yokwenyani enokutshintsha i-voltage kunye nesantya sokuhamba komatshini wokuhlamba iimoto. Ngokwesiqhelo, yi-motor encinci eyi-0.4 efakwa emzimbeni ohambayo, kwaye ayinakuseta iimodeli ezahlukeneyo ezifana noxinzelelo lwe-Hi&low lokutshiza amanzi kunye nesantya se-Hi&low sabalandeli. Okubi nangakumbi, ukuba ayisiyo-frequency converter, xa umatshini uqala ukusebenza, i-instant current iphindwe ka-6-7 kune-general current, kuya kuba lula ukubangela umonakalo kwi-circus kunye nokuchithakala kombane.
Umatshini wokuhlamba iimoto we-CBK usebenzisa itekhnoloji yokuguqula iifrikhwensi ze-18.5kw ukuqhuba, kwaye ngenxa yoxinzelelo oluphezulu noluphantsi lokutshiza ngamanzi kunye nesantya esiphezulu noluphantsi sabalandeli, ukusetyenziswa kombane kuya konga ngaphezulu kwe-15%, oko kuthetha ukuba umnini angamisela nayiphi na inkqubo ayifunayo. Ke ngoko, umatshini wokuhlamba iimoto we-CBK unokunciphisa isidingo sokulungiswa kunye neendleko ezihambisana nawo.
Ngokwesiqhelo, nantoni na enenjini ngaphakathi iya kufuna i-frequency converter, kwaye umatshini wokuhlamba iimoto we-CBK unokwenza loo nto.
