Smooth isiqalo yoqheliso motor: isixhobo, isiphaluka

ukubala Soft ziyafumaneka Iimowutha olungenangqamaniso bamandla ezahlukeneyo. imifuziselo abaninzi ijolise kanye ngqo ekunikeni lunikezelo. Nangona kunjalo, kukho sisimo abakwaziyo ukunika stop smooth injini. Yokuqala lisetyenziswe ngokufuthi phezu zokuthutha.

nabo ke efakwe kwi amabhanti okuhambisa. Kuba iimpompo, ayadibana ngokugqibeleleyo. Umgaqo esebenza ngayo imifuziselo eyakhelwe ngokuthe ekunciphiseni iparameter umthwalo yangoku. Ukuze siyiqonde ngakumbi kule nkalo, cinga ifowuni ukuziqalela elula.

standard ukuziqalela Scheme

Umva circuit yoqheliso motor yokuqala luquka sombane step-phantsi uhlobo. Le relay kule meko kuzakucwangcisa ombane aphezulu ngokubhijela kwaye ukumelana ukucima kombane elikhulu kunene. Ukuba sicinga imifuziselo enamandla, ngoko ke rectifiers.

Kwakhona, i-injini induction ukuqala beesekethe kubandakanya ukusetyenziswa resistors podstrochennogo uhlobo. Kwezinye sisimo, inokufumaneka transceiver. Ezi zixhobo zenzelwe ukuba ukunciphisa amaza iwashi motor induction. Ngenxa yoko, zinokuhlala iminyaka emininzi. Kenotrons imifuziselo ezisetyenziswa ekwenzeni.

Yokuqala motor-Isigaba esinye

Soft isiqalo yoqheliso isithuthi ngenxa ukuziqalela ezi-kungenxa sombane na amandla. Okulandelayo kokuba inikezelwa le relay, apho uguqulelo kwenzeka. Uninzi iinguqulelo kule hlobo zixhotyiswe nge wegazi. Zisetyenziswa ikhowudi kuphela, okanye ukucofa-up. To connect iziphumo kukho imoto induction iyasetyenziswa.

Ezinye iinguqulelo zithengiselwa kunye nabalawuli. Rectifiers zifakwa ezisebenza ngqo. imifuziselo Ipharamitha umbundu omninzi ayidluli 40 A. Ngenxa yoko, umthamo wabo kwinqanaba 5-10 kW. Ipharamitha Ibanga unikezelo ombane ukusuka 100 ukuya -220 V. Ngokutsho neqondo lokhuselo kwesigaba esinye ukulungisa zahluke kakhulu omnye komnye. Ezinye zazo asesichengeni ukufuma kunye eluthulini, yaye oku kufanele kuqwalaselwe phambi kokuthenga.

Icebo of iimodeli phase-amabini

Yokuqala phase-wonke ezimbini kufuneka siqwalasele umzekelo imifuziselo zemveliso jikelele. Olu hlobo iinjini yoqheliso (ontlantlu-ntathu) iinkcukacha zezi zilandelayo: amandla 5-15 kW, ukucima kombane ubuninzi 40 A, izinga igalelo lombane 220 V. Izikhonkwane zisetyenziswa kunye kuhlenga-primary jiko. Le modeli basebenzisa uhlobo abaguquli, inyathelo-phantsi. Kubalulekile ukuba uqaphele ukuba baphinde zibekwe kunye ekwenzeni. Modulators kwezi zixhobo kuphela orthogonal ezifanelekileyo. Ukulungiswa ukuya resistors zinqabile kakhulu.

Ukuguqulwa lohlobo ontlantlu-ntathu

isiqalo elithambileyo motor induction kusetyenziswa ukubala ontlantlu-ntathu fast. Ukuba sithethe ngeempawu imifuziselo, kubalulekile ukuqaphela ukuba isixhobo threshold unako ukumelana umthwalo kwi-avareji yama-60 A amandla imifuziselo ezininzi ngaphezu kwe-5 kW. A Ububi zezi zixhobo kuthathwa ukuba kwamaqondo obushushu asezantsi zisembundwini wawo. Neqabaka aluvumelekanga ngokungqongqo yokuzisebenzisa. Modulators njengezibonelo uhlobo orthogonal afanelekileyo.

Dilators rhoqo ukuhlangabezana ikhowudi. I Parameter ye bandwidth yangoku zahluke kakhulu. Transceiver zikholisa efakwe kwi esibondeni Yokuqala. Transistors onobuhle ikakhulu kusetyenziswa lwebhendi ebanzi. Neqondo lokhuselo Yokuqala ezahlukeneyo. Uninzi lwazo ukoyika ukufuma eziphakamileyo, kodwa kulo mzekelo, ubukhulu becala kuxhomekeke kumenzi.

Starter njengezibonelo kunye plane nomatse-yokuhlala

Nge unomatse cage Motors yoqheliso (ontlantlu-ntathu) iinkcukacha zezi zilandelayo: amandla 10 kW, ukucima kombane iphezulu yi-40 A, umyinge wokuphelelwa igalelo yangoku 220 V. Uninzi abaguquli zokuqalisa baxhotyiswe uhlobo phantsi. Ezinye izilungiselelo kwimarike kwafakwa ekwenzeni. Kubalulekile ukuba uqaphele ukuba uhle umthamo kwama-12 kW baxhotyiswa dinistorov okhethekileyo.

Ngokuba sinjalo, ukuba ombane yemveliso efanelekileyo. Wegazi kuzo zonke izixhobo usebenzise ikhowudi. Nangona kunjalo, le thyristors kuphela uhlobo semiconductor efanelekileyo. Kwi-avareji, ubushushu ubuncinane ekwaziyo ukugcina isixhobo degrees 5. Ngoko nangoko ukuqala motor yoqheliso kunye unomatse endlwaneni ngokusebenzisa nabo imveliso kwi ngaphezulu yezindlu.

Amanqaku imizekelo motor eliphezulu-ombane start-up

Soft isiqalo yoqheliso ngeemoto yenziwa ngokusebenzisa abaguquli amandla eliphezulu-ombane. Apha, kuphela nabalawuli kagesi asetyenziswa ukulawula. Kenotrons ebekwe ngqo rhoqo. Transistors kwezi modeli zilufanele ekwiqondo eliphezulu. Insulators e izixhobo, kukho iindidi ezimbini. To connect Iimoto eliphezulu-ombane abafowunelwa output ziyasetyenziswa. Onobuhle dinistorov ezinqabileyo.

Yokuqala series ABB

Yokuqala kolu ngcelele zithathwa ukuba ivame kakhulu. Kulo mzekelo, ukuqala injini kwenzeka ngenxa kwisigaba shift. ukuguqulwa ngqo yangoku luyenziwa phakathi dinistorov. Xa uhlobo iimodeli relay zahluke kakhulu. Imifuziselo Power ezisukela-4 ukuya ku-12 kW. Ngenxa yoko, le ombane supply umlinganiselo 220 V. Ivaluva efakiweyo uhlobo ikhowudi kuphela.

Ukuba uthethe modulators, imifuziselo aphezulu amandla, ukuba orthogonal. Kubalulekile ukuba uqaphele ukuba transceiver kuzo zonke ukubala kolu pole ngcelele. Amaninzi, imodeli ingafunyanwa kwi zokuthutha. Ekwenzeni kwi isixhobo ashiyiweyo. inkqubo yokhuseleko abafake uthotho IP-62, kunye nokufuma phezulu kwayo ungoyiki.

Device eyaqala "Schneider"

Said ukuziqalela yohlukile igalelo ombane aphezulu 200 V. Kulo mzekelo, i-injini ukuqala-up nge sombane ngamandla. Ukuthumela le modeli lisetyenziswa kunye primary jiko. Ngokutsho amaxwebhu kwisixhobo omninzi umbundu Ukumiswa kwinqanaba A. resistor 40 ezinemifanekiso postroechnyh iseti yolungiselelo kunye extender kusetyenziswa uhlobo khowudi. Iingxaki kunye utshintsho kwisigaba kwefowuni kwenzeka ngamaxesha. Ukuguqula modulator ngoku kuyasebenza umgangatho. Speed isilawuli olungenangqamaniso motor electromagnetic uhlobo. Dynistor umenzi linikwa ukwandiswa imodeli le hlobo. Icebo zener intanethi.

Yokuqala imikhumbi

Iimfaniso iinqanawa ziyafumaneka ngokwezikhundla ezahlukeneyo. E waqala. injini ngokusebenzisa sombane ngamandla. Ukuba sicinga iinguqulelo kwisigaba-mbini, ukuba ifakwe rectifiers. Modulators, ke, zichazwe njengoko orthogonal kunye beskondensatornogo uhlobo. Resistors zidla kusetyenziswa izikhwezeli. phase-Ezintathu ukubala ukulungisa kwafakwa ekwenzeni. Ukutshintsha iwotshi frequency thyristors ezisetyenzisiweyo. Kenotrons kulo mzekelo zibekwa kunye umthamo omkhulu.

imifuziselo zeemodyuli sesakhiwo zenyukliya

ukubala seemodyuli luphawulwa ombane enkulu parameter. E waqala. injini ngokusebenzisa abaguquli step-phantsi uhlobo. Ngokuba models kwisigaba-ezimbini analogue amandla zisetyenziswa kunqabile kakhulu. Rectifiers baphinde kuphela ezifakwe ngamayelenqe. Wegazi zisetyenziswa uhlobo yodayalo ye-EGPRS.

Degree ukhuseleko esilungiselelwe ukubala Series SP-67. ukufuma High kunye nothuli iipateni ningenaxhala naloyiko. Insulators kwizixhobo luyafumaneka iiyunithi ezintathu ukuya kwezintandathu. Ukutyeba yahluka ukusuka-4 ukuya kwi-10 kW. Umalusi isantya motor olungenangqamaniso befumana uhlobo electromagnetic. Kubalulekile ukuba uqaphele ukuba iiyunithi thyristor semiconductor zifakwa kunye nabo.

isixhobo zeemodyuli yezikhululo lift

a Yokuqala phase-ezimbini zisetyenziswa yezikhululo lift. Qala motor induction usebenzisa zokuqalisa umsebenzi kwimeko langoku kwenziwa usebenza phantsi sombane. omninzi lwangoku le mifuziselo kufuneka ukuba agcine-40 A. ezifane izinto ezithile amandla uninterruptible ngokuqhelekileyo kusetyenziswa uhlobo lwe khowudi.

Transceiver zisetyenziswa esibondeni ngqo. Le modulators kulo mzekelo zisetyenziswa enqabile. Nangona kunjalo, kukho ulungiso ukuya nabalawuli. Resistors asetyenziswa neemodeli le ngombala, kunye nohlobo ukubetha. Ulungiso ityhubhu ivalve kwimarike azenzeki. Nge ukuxinana kakhulu iibhloko transistor umsebenzi. Kubalulekile ukuba uqaphele ukuba imifuziselo kusetyenziswa insulators.

Iimpawu Models 60 A

Yokuqala 60 A yezikhululo lift zezona. isiqalo kakuhle yoqheliso motor kulo mzekelo ezinikezelwa transformer ngamandla. Le relay iye imifuziselo ezininzi kunye primary jiko.

Kuba ukusebenza okuqhelekileyo starter kusetyenziswa modulators kuphela orthogonal. Ngoko nangoko iiyunithi thyristor kunokubonwa uhlobo semiconductor. umthwalo umbundu bakwazi ukumelana enkulu. Imifuziselo Power on kumaqondo avareji ukusukela 10 kW.
