Converters Ubuninzi Iimowutha induction: siseko ukusebenza kunye nokugcinwa

Namhlanje, converters rhoqo Iimowutha induction ngokufuthi zisetyenziswa kolu shishino. Kubalulekile ukuqaphela ukuba ezi injini na engathi zabo isakhiwo ezintathu, abaqhagamshelwe kwi "inkwenkwezi" okanye "unxantathu". Kodwa ukuba ethile omnye - lungisa isantya plane kunzima kakhulu. Kodwa loo nto ngaphambili. Ngoku, xa kuziwa uncedo electronic micro namandla, lo msebenzi kuba lula. Tyhila resistor elitshintshayo uyakwazi ukutshintsha ngesantya uluhlu olubanzi.

Ngayiphi injongo efunekayo frequency converter?

Imisebenzi kule mveliso baninzi, kodwa inkoliso imali encinane ezisetyenzisiweyo. Enyanisweni, ukulawula injini olungenangqamaniso kuyimfuneko ukuba ukwazi ukunyenyisa kuphela isantya ojikeleza ngaso kodwa ixesha ukukhawulezisa, deceleration. Ukongeza, nayiphi na inkqubo ifuna ukhuseleko. Kuyimfuneko ukuba ukuthatha ingqalelo Converter frequency lwangoku, esebenzisa i motor induction.

Zazisetyenziswa chastotniki kwiinkqubo umoya. Nangona lula elikhangeleka kweevili fan, umthwalo kwi plane makhulu kakhulu. Kwaye ukukhawulezisa ekhawulezayo akunakwenzeka. Kwakhona, kukho iimeko apho imfuneko ukunyusa isantya ojikeleza ngaso, ukuhamba umoya waba ngaphezulu okanye ngaphantsi. Kodwa kuphela umzekelo, kukho rhoqo converter isoloko isetyenziswa kwezinye iindlela. Kunye chastotnika Ungahlela isantya yokuthutha, eliquka yimivumbo eziliqela.

Umgaqo esebenza ngayo amaza yokuguqula

Isiseko le ulawulo isilawuli kunye neziphaluka ezininzi lokuguqula AC kunye DC yombane. iinkqubo ezininzi kunye ombane onikezelwa input ngamandla isixhobo. sokuquqa Work Converter ilula, lwanele siqwalasele ngamanqanaba amathathu. Okokuqala, kukho nokolula apho. Okwesibini, ucoco. Okwesithathu, lo inversion - uguqulo ka-DC kwi AC.

Kuphela kwinqanaba lokugqibela ukutshintsha iimpawu kunye izicwangciso zangoku. Xa angafaniyo iimpawu zangoku ungalawuleka isantya ivili le motor emgudu munye. Xa inverter inqanaba kusetyenziswa kwindibano onamandla transistors. Ezi zinto zintathu O - amandla ezimbini nolawulo omnye. Ukususela ubukhulu uphawu isicelo yokugqibela kuxhomekeke uphawu lwangoku-ombane kwi imveliso chastotnika.

I drive na indawo?

converters Ubuninzi Iimowutha olungenangqamaniso baqalisa ukusebenzisa kakhulu kutshanje. Kodwa inzululwazi kancane apho, waye ohlukahlukeneyo plane yokuqala isantya ojikeleza ngaso usebenzisa amagiya okanye variator. Noko ke, ulawulo onjalo ngumsina kakhulu, kwaye namandla drive itshile ngenxa iindlela ezingeyomfuneko. yokudlulisela Belt kunceda ukunyusa isantya ujikelezo, kodwa loo nto kanye ukuseta zokugqibela iparameters kunzima kakhulu. Ngenxa yezi zizathu, le VSD ingcono kakhulu, ekubeni ayisebenzisi ukulahleka amandla. Kodwa okona kubalulekileyo - it likuvumela ukuba utshintshe i parameters drive, ngaphandle kokutshintsha ubucukubhede.

Yeyiphi inverter ukukhetha ukusetyenziswa ekhaya?

Kufuneka kuqatshelwe ukuba uqhagamshelwano yenziwe kwinethiwekhi olulodwa kunye ontlantlu-ntathu ngoku. Konke kuxhomekeke imodeli drive ethile, yaye ukuba ngokukodwa, apho umphathi wesekethe inverter le injini induction ezisetyenziswa kwimveliso. Ukuze siqonde umgaqo ukusebenza, kwanele ukuba ukujonga isakhiwo kwefowuni. Icandelo lokuqala - i rectifier, apho kwenzekayo ilight semiconductor. Le wesekethe ibhulorho lokuguqula eyodwa okanye ezintathu Isigaba AC ukuya DC. Kuba izixhobo ezisebenzisa kufuneka ukhethe ezo iimodeli chastotnikov zabo izimvo uqhagamshele ezi-ifildi yangoku. ukhetho Related ukuba emakhayeni ukuqhuba uthungelwano ontlantlu-ntathu kuyingxaki, yaye hayi inzuzo, ngenxa yokuba kufuneka usebenzise nobunzima kakhulu ngenxa esebenza zombane.

Awona macandelo aphambili drive

Little kuthiwe ukuba le sekethe i inverter. Kodwa kufuneka siqonde ukuba iinkcukacha ukufunda eneenkcukacha. Xa ukuguqulwa Isigaba sokuqala - AC ukulungisa. Enoba kakhulu kwisigaba igalelo inikezelwa (enye okanye amathathu), xa imveliso ye rectifier wena ufumane unipolar lombane 220 volts rhoqo (dibanisa enye thabatha enye). Kuyinto kakhulu phakathi lesigaba kunye cala.

Oku kulandelwa iyunithi filter, nto leyo inceda azisusi onke amacandelo eziguquguqukayo ye yangoku bulungiswe. Kwaye eqongeni lokugqibela kakhulu into zocaphulo - ukusuka DC iyaguquguquka esebenzisa transistors amandla, nelawulwa yi-microcontroller. Ngokuqhelekileyo, inverters Iimowutha induction babe umboniso ezinombala LCD, ebonisa imida ezifunekayo.

Ngaba kunokwenzeka ukuba idivaysi ngokwakho?

Ukuveliswa ifowuni ezinxulumene neengxaki ezininzi. Kufuneka ufunde izisekelo microcontrollers zokuhlela ukwandisa amathuba eso sixhobo. Kubalulekile ukuthatha ingqalelo zonke iimfuno ezisisiseko. Umzekelo, ukuvalwa olungxamisekileyo oluzenzekelayo xa edlula kuvumelekile yangoku eliphezulu nto leyo ndiyaphela enjinini. Ukuze wenze oku, kufuneka ukucwangcisa imveliso current, nto leyo iza kwenza phakathi kwehlabathi esweni rhoqo. Kwakhona, kufuneka inike izinto Ukupholisa esebenzayo yaye angenzi inkqubo samandla - ode kunye transistors, kwaye kananjalo khubaza isixhobo kwi zokufudumeza kakhulu. Kuphela kulo mzekelo, converters rhoqo Iimowutha olungenangqamaniso kungenziwa eziqhutshwa ngokukhuselekileyo.
