Ngaba i-Guruable Frequency Drive inoKutshintshwa YiMotor Soft Starter?

Ndidibana nabathengi abaninzi abandibuza imibuzo emininzi kwaye ndinelunda kakhulu ukudibana nabo kwaye ndithethe nabo malunga nolawulo lokuqalisa iimoto.Abanye abathengi bahlala bezibuza ukubaiidrive frequencyinokutshintshwa yiiziqalisi ezithambileyo.Namhlanje ndiza kukunika ingcebiso:

1. Umgaqo wolawulo we-soft starter kunye ne-frequency converter iyahluka

Isekethe engundoqo ye-starter ethambileyo idityaniswe kuthotho phakathi konikezelo lwamandla kunye nemoto kwi-thyristor ezintathu ezichaseneyo ezichaseneyo, ngokusebenzisa isekethe yangaphakathi yedijithali ukulawula i-thyristor kwi-waveform ye-sinusoidal epheleleyo yokutshintshiselana kwexesha langoku, ukuba ekuqaleni. yomjikelezo we-AC vumela i-thyristor ivule, ngoko i-voltage ephumayo ye-starter ethambileyo iphezulu, Ukuba i-thyristor itshintshelwe kwindawo ethile kumjikelo wangoku okutshintshayo, imveliso yombane ye-soft starter iphantsi.Ngale ndlela, senza i-voltage ekupheleni kwe-motor ngokucothayo ukunyuka kwinkqubo yokuqala, kwaye emva koko silawule ukuqala kwangoku kunye ne-torque ye-motor, ukuze i-motor ikwazi ukufezekisa injongo yokuqalisa okuzinzile.Ingabonwa ukuba i-soft starter inokutshintsha kuphela inqanaba le-voltage yonikezelo lwamandla, kodwa kungekhona ukuphindaphinda kokunikezelwa kwamandla.
Umgaqo wokuguqula rhoqo unzima kakhulu.Umsebenzi wayo kukutshintsha i-voltage ye-380V / 220V kunye ne-frequency ye-50HZ unikezelo lwamandla kwisixhobo sokuguqula amandla e-AC kunye ne-voltage adjustable and frequency.Ngokulungelelanisa ukuphindaphinda kunye nokuphindaphindiweyo kokunikezelwa kwamandla, i-torque kunye nesantya se-AC motor inokulungiswa.Isekethe yayo ephambili yisekethe eyenziwe ngeetyhubhu ezi-6 zempembelelo yentsimi, phantsi kolawulo oluchanekileyo lwesekethe yolawulo, ukuze iityhubhu zempembelelo zentsimi ezintandathu zivule, ngexesha leyunithi, ngakumbi inani letyhubhu, emva koko i-voltage ephumayo kunye namaxesha. iphezulu, ngoko ke isekethe ephambili iphantsi kolawulo lwesekethe yolawulo lwedijithali ukufezekisa ukulawulwa rhoqo konikezelo lwamandla ombane kunye nommiselo wombane.

2. Ukusetyenziswa kweumqalisi othambileyokunye ne-inverter yahlukile

Ingxaki ephambili ye-soft starter kukunciphisa ukuqala komthwalo onzima kunye nokunciphisa impembelelo kwigridi yamandla.Ukuqaliswa kwezixhobo ezikhulu kuya kuvelisa umbane omkhulu kakhulu, oya kubangela ukuhla kwamandla ombane.Ukuba imowudi yendabuko yokuhla ezantsi njengonxantathu weenkwenkwezi isetyenzisiwe, ayiyi kubangela kuphela impembelelo enkulu yangoku kwigridi yamandla, kodwa ibangele impembelelo enkulu yomatshini kumthwalo.Kule meko, isiqalisi esithambileyo sihlala sisetyenziselwa ukuqalisa, ukuze kuqatshelwe yonke isiqalo ngaphandle kwempembelelo kwaye yenze ukuba imoto iqale ngokutyibilikayo.Ngaloo ndlela amandla amancinci.

Ukusetyenziswa kweisiguquli rhoqoisetyenziswa ikakhulu kwindawo enolawulo lwesantya, inokulawula isantya semoto enezigaba ezithathu, njengakumatshini weCNC wokulawula isantya semoto, ukulawulwa kwebhanti lokuhambisa ngoomatshini, iifeni ezinkulu, usetyenziso lomatshini onzima lunokusetyenziswa isiguquli samaza, ngokubanzi, umsebenzi waso uyasebenza kakhulu kunesiqalisi esithambileyo.

3. Umsebenzi wokulawula we-frequency converter ye-soft starter iyahluka

Umsebenzi ophambili wesiqalisi esithambileyo kukulungelelanisa umbane wokuqalisa wemoto ukuqonda ukuqala okugudileyo kwemoto ukuze kuncitshiswe impembelelo yemoto koomatshini kunye negridi yamandla.Nangona kunjalo, ngenxa yokuba ilawula i-voltage nge-chopper ngokulawula i-Angle yokuqhuba, imveliso ayiphelelanga i-sine wave, ekhokelela kwi-torque ephantsi, ingxolo enkulu kunye ne-harmonics ephezulu iya kungcolisa igridi yamandla.Nangona umqalisi othambileyo ukhawulelwe kulungiselelo lomsebenzi womjelo, ukusetwa kwexesha lokuqala kunye neminye imisebenzi, kodwa ngesiguquli esiphindaphindayo, iiparamitha ezisebenzayo zomqalisi othambileyo zinothoni.Ngokubanzi, umsebenzi we-soft starter awukho kangako njenge-converter frequency.

4. Ixabiso le-soft starter yahlukile kwi-converter frequency

Izixhobo ezimbini zokulawula kwimeko efanayo yamandla, ukusuka kwixabiso le-inverter liphezulu kune-soft starter.

Ngokubanzi, isiqalisi esithambileyo sisetyenziswa ikakhulu kwizixhobo zamandla aphezulu njengesixhobo sokuqalisa, kwaye isiguquli samaza sisetyenziswa ikakhulu kulawulo lwesantya samandla ahlukeneyo.Kwiimeko ezininzi, isiguquli sokuphindaphinda asikwazi ukutshintshwa sisiqalisi esithambileyo.
