IV. Letoto le leng la VFD
Ho phaella letotong le ka holimo, INVT e boetse e hlahisitse mefuta e meng e fapaneng ea lihlahisoa tsa VFD, tse kang letoto la GD20, letoto la ES840, joalo-joalo Lihlahisoa tsena li boetse li na le litšobotsi tsa ts'ebetso e phahameng le ho boloka matla, taolo e nepahetseng, tlhokomelo e bonolo le ts'ireletso ea ts'ireletso, 'me li loketse mefuta e sa tšoaneng ea li-motors tsa AC le tsamaiso ea tsamaiso.
Lihlahisoa tsa letoto la INVT VFD: E etella pele khaolo e ncha ea ho khanna indasteri

Lihlahisoa tsa letoto la INVT VFD ke moloko o mocha oa li-drive frequency frequency drive tse ntlafalitsoeng ka hloko ke INVT ho ipapisitse le lilemo tse fetang leshome tsa boiphihlelo bo bokelletsoeng indastering ea crane le thekenoloji ea taolo e tsoetseng pele. Lihlahisoa tsena li kopanya letlotlo la mesebetsi e khethehileng ea taolo bakeng sa indasteri ea ho phahamisa le ts'ebetso e sireletsehileng ea torque off (STO), 'me e ka sebelisoa haholo li-cranes tse fapa-fapaneng likarolong tse fapaneng tse kang likoung, lifeme, libaka tsa kaho le merafo, ho bontša ts'ebetso e babatsehang ea taolo, ts'ebetso e pharaletseng ea ts'ireletso ea ts'ireletso le bokhoni ba ho atolosa habonolo.

Matla a matla a lihlahisoa tsa letoto la INVT VFD a pharaletseng, a koahela 1.5 ~ 500kW ea AC 380V (-15%) ~ 440V (+10%) le 22 ~ 630kW ea AC 520V (-15%) ~ 690V (+ 10%). Sena se ba nolofalletsa ho kopana le lits'ebetso tsa indasteri tsa boholo le litlhoko tse fapaneng.

Mabapi le ts'ebetso, letoto la INVT VFD le na le likarolo tse 'maloa tse hlokomelehang. Ntlha ea pele, ba na le matla a matla a ho hlahisa torque e tlaase, e khonang ho fana ka torque ea 0Hz / 200% (e lekantsoeng) ka mokhoa oa ho laola vector (FVC), le 0.5Hz / 150% (torque e lekantsoeng) ka mokhoa oa ho laola vector ea sebaka. Sena se nolofalletsa crane ho sebetsa hantle le ka katleho tlas'a maemo a fapaneng a mojaro.

Taba ea bobeli, letoto la INVT VFD le na le matla a ho ikamahanya le maemo. Ka li-algorithms tse ntlafalitsoeng tsa taolo, li ka fetola torque ea tlhahiso ho latela maemo a mojaro, ho etsa bonnete ba hore crane e ka fana ka matšeliso a babatsehang ha e laolloa kapa e laeloa.

Ntle le moo, letoto la INVT VFD le boetse le na le mefuta e fapaneng ea mesebetsi e ikhethang bakeng sa lits'ebetso tsa crane. Mohlala, li ts'ehetsa taolo e sa sebetseng ea eddy ea hajoale ea li-crane tsa tora, e khona ho emisa braking ka potlako, e fihlelle ho ea pele ka lebelo le ho furalla le ho beha maemo a tlase ka lebelo le tlase. Ka nako e ts'oanang, ba ka boela ba fetola matla a khoheli ho latela litšobotsi tsa li-conical rotor motors, ho finyella ho lokolloa ha brake ka potlako le ho laola ho koala, ho nolofatsa mehato ea ho laela le ho netefatsa tšireletso ea lisebelisoa.

Mabapi le polokeho, letoto la INVT VFD le lona le sebetsa hantle. Li kopanya ts'ebetso ea ho netefatsa torque ho netefatsa ts'ebetso e bolokehileng le e sa thelleng kamora hore torque e thehoe. Ka nako e ts'oanang, ba boetse ba ts'ehetsa ts'ebeliso ea khetho ea tataiso ea ho qala le khetho ea brake ho ea pele le ho khutlisetsa morao ho fihlela litlhoko tse fapaneng tsa ho qala. Ntle le moo, letoto la INVT VFD le boetse le na le mesebetsi e kang ts'ireletso ea moeli o holimo le o tlase le ts'ireletso ea moeli oa holimo le o tlase, e ka fokotsang crane ho sebetsa ka har'a mefuta e itseng, ho netefatsa polokeho le ho ntlafatsa mokhoa oa ho koala ho ntlafatsa ts'ebetso ea lisebelisoa.

Ho bohlokoa ho bolela hore letoto la INVT VFD le lona le na le ts'ireletso ea anti-sway. Ba sebelisa algorithm ea anti-sway control e se nang kutlo, e ka lokisoang habonolo le ho feto-fetoha le maemo ho latela litlhoko tsa taolo ea anti-sway tsa li-cranes tse fapaneng. Ho feta moo, ba boetse ba na le ts'ebetso ea ts'ireletso ea thapo e hlephileng ho qoba ho phahamisa lebelo le phahameng, ho hloleha ho potlakisang le likotsi tsa polokeho sebakeng se hlephileng sa thapo.

Mabapi le ho boloka matla le ts'ireletso ea tikoloho, letoto la INVT VFD le lona le sebetsa hantle. Ba ka fokotsa tšebeliso ea matla ka ho laola lebelo le matla a enjene ka nepo. Ha ho bapisoa le li-drive tsa setso, letoto la INVT VFD le ka fetola lebelo le matla a koloi ka bo eona tlas'a meroalo e fapaneng ea mosebetsi, ka hona la fumana tekanyo e phahameng ea matla a matla. Ka nako e ts'oanang, li boetse li na le lerata le thothomelang le fokolang, 'me li na le tšusumetso e fokolang tikolohong.

Ka kakaretso, lihlahisoa tsa letoto la INVT VFD li fetohile matla a bohlokoa lefapheng la likoloi tsa indasteri ka ts'ebetso ea tsona e ntle haholo, masimo a ts'ebeliso e pharaletseng le litšobotsi tse ikhethang tsa ho boloka matla le ts'ireletso ea tikoloho. Ebang ke indastering ea crane kapa masimong a mang a indasteri, lihlahisoa tsa letoto la INVT VFD li ka fa basebelisi tharollo e sebetsang, e tšepahalang le e bolokehileng ea koloi. Ka tsoelo-pele e tsoelang pele ea theknoloji le katoloso e tsoelang pele ea masimo a kopo, lihlahisoa tsa letoto la INVT VFD ehlile li tla bapala karolo ea bohlokoa ho nts'etsopele ea indasteri e tlang.
