Mosebetsi oa inverter ke ho fetolela maqhubu a tsitsitseng le phepelo ea motlakase ea AC hore e be phepelo ea motlakase ea mekhahlelo e meraro ea AC e nang le maqhubu a feto-fetohang le voltage. Variable Frequency Drive (VFD) ke sesebelisoa sa elektroniki sa matla se fihlelang taolo e nepahetseng ea lebelo la koloi le matla a tsoang ka ho fetola maqhubu le amplitude ea motlakase o sebetsang. Pampiri ena e tla fana ka kenyelletso e qaqileng ea mesebetsi ea mantlha le likarolo tsa ts'ebeliso ea li-inverters.
Karolo ea mantlha ea sesebelisoa sa frequency converter.
a) Mosebetsi oa taolo ea lebelo:
Mosebetsi oa mantlha oa inverter ke ho fihlela taolo e nepahetseng holim'a lebelo la ts'ebetso ea enjene. Ka ho lokisa frequency le voltage ea phepelo ea motlakase ea ho kenya, inverter e netefatsa lebelo le tsitsitseng nakong ea ts'ebetso ea motlakase, ka hona e fihlela litlhoko tse fapaneng tsa ts'ebetso.
b) Phello e babatsehang ea ho boloka matla:
Inverter e fokotsa ts'ebeliso ea motlakase ka katleho, ka hona e fokotsa tšebeliso ea matla. Ka ho sebelisa matla a hlokahalang feela nakong ea ts'ebetso ea motlakase, tšebeliso e feteletseng ea motlakase e qojoa. Sena ha se fokotse feela litšenyehelo tsa tlhahiso empa hape se fokotsa khatello ho marang-rang le ho khothaletsa mekhoa ea tlhahiso e baballang tikoloho.
c) Ho ntlafatsa katleho ea tlhahiso:
Mofetoleli oa maqhubu o thusa ho laola ka mokhoa o itekanetseng oa ts'ebetso ea tlhahiso, ho ntlafatsa katleho ka kakaretso. Liindastering tse kang lik'hemik'hale le peterole, mohlala, inverter e fetola lebelo la koloi ka bo eona ho latela litlhoko tsa tlhahiso, e leng se hlahisang tlhahiso e ntlafetseng le boleng ba sehlahisoa.
d) Botšepehi bo ntlafalitsoeng ba sesebelisoa:
Inverter e kenyelletsa mesebetsi e fapaneng ea ts'ireletso joalo ka ts'ireletso ea boima bo feteletseng le thibelo ea mocheso o feteletseng ho sireletsa li-motor hore li se ke tsa senyeha tlasa maemo a sa tloaelehang. Ho feta moo, ho lekola tšebetso ea makoloi ka nako ea 'nete ho lumella ho lemoha mathata a ka bang teng pele, 'me qetellong ho lelefatsa bophelo ba lisebelisoa.
Likarolo tse tsoetseng pele tsa li-inverters:
a) Taolo ea lebelo le fapaneng:
Li-inverters li tšehetsa litlhophiso tsa lebelo tse feto-fetohang tse ka fetoloang ho latela litlhoko tse ikhethileng tsa ts'ebetso, tse nolofalletsang lits'ebetso tsa taolo ea makoloi tse fapaneng le tse nang le merero e mengata. Mohlala, lits'ebetso tsa lifti li sebelisa lebelo le fapaneng la ts'ebetso le behiloeng ke li-inverters ho ntlafatsa ts'ebetso e sebetsang mekatong e fapaneng.
b) Ho tsamaisana ka boiketsetso:
Li-inverters li na le ts'ebetso ea othomathike e bapisang litšobotsi tsa koloi le ho fetola liparamente ho latela litlhoko tsa 'nete. Tšobotsi ena e tiisa ho lumellana pakeng tsa mefuta e fapaneng le litlhaloso tsa li-motor ha li ntse li fokotsa litšenyehelo tsa tlhokomelo ea thepa.
c) Mosebetsi oa puisano:
Li-converter tsa sejoale-joale li na le likhokahano tsa puisano bakeng sa phapanyetsano ea data le lisebelisoa tse ling kapa litsamaiso
Sebaka sa ts'ebeliso ea frequency converter
Li-converter tsa maqhubu, joalo ka lisebelisoa tse tsoetseng pele tsa taolo ea matla, li fumana lits'ebetso likarolong tse fapaneng. Mona ke tse ling tsa maemo a tloaelehileng:
a) Ho fehla matla a moea:
Lebelo la li-turbine tsa moea tsamaisong ea matla a moea le hloka ho lokisoa ho latela lebelo le fetohang la moea bakeng sa ho boloka phepelo ea motlakase e sebetsang hantle. Li-converter tsa maqhubu ka nepo li laola li-turbine tsa moea le ho ntlafatsa katleho ea tlhahiso ea matla.
b) Boiketsetso ba indasteri:
Lits'ebetsong tsa tlhahiso ea indasteri, lisebelisoa tse ngata li hloka taolo ho latela litlhoko tsa tlhahiso. Taolo e nepahetseng ea lisebelisoa tsena ka ho sebelisa li-frequency converter e ntlafatsa katleho ea tlhahiso le boleng. Mohlala, li-inverters li sebelisoa haholo indastering ea lik'hemik'hale, peterole, ea meriana bakeng sa taolo ea lebelo la mabanta a conveyor, li-compressor, li-mixer, jj.
c) Kaho le thepa ea ka tlung:
Li-inverters li sebelisoa bakeng sa taolo ea lebelo la sistimi ea moea, lipompo tsa metsi, joalo-joalo, makaleng a kaho le a thepa ea ka tlung. Ka ho laola ka nepo lebelo la ts'ebetso ea lisebelisoa, ts'ebetso e ntlafatsoa ho fihlela maemo a bophelo a boiketlo le a bolokang matla. Ka mohlala, ka har'a moelelo oa tsamaiso ea lapeng e bohlale; li-inverters li ikamahanya le lebelo la ho sebetsa li-air conditioner ho ipapisitsoe le mocheso oa kahare / kantle ho boloka maemo a mocheso / mongobo o sa feleng.
d) Lipalangoang:
Lisebelisoa tsa motlakase litereneng le likoloing tsa motlakase li hloka liphetoho ho latela maemo a ts'ebetso. Taolo e nepahetseng ea litsamaiso tsena tsa matla ka li-inverters e ntlafatsa ts'ebetso ea ts'ebetso le mehato ea polokeho. Lits'ebetso tsa literene joalo ka literene tse tsamaeang ka tlas'a lefatše kapa liporo tse bobebe li sebelisa li-converter tsa maqhubu ho laola lebelo la terene/ho theola/ho emisa ho netefatsa ts'ebetso e bolokehileng le ho fihla ka nako.
