Smooth isiqalo lokungeniswa motor: idivayisi, isifunda

temusho Soft ziyatholakala motors indlela kwamandla ezahlukene. onobuhle Abaningi okuqondiswe ukuhlinzeka ukushesha. Nokho, kukhona ukucupha ukuthi ukwazi ukunikeza bushelelezi injini stop. Yokuqala elisetshenziswe kaningi phezu zokuthutha.

nazo efakwe amabhande elihambayo. Ukuze amaphampu, bona uvumelane ngokuphelele. Isimiso ezisebenza models eyakhelwe elokhu enciphisa zamanje umthwalo ipharamitha. Ukuze uzwisise kabanzi kule ndaba, cabanga kudivayisi ukuziqalela elula.

Isikimu ejwayelekile ukuziqalela

Esethola lokungeniswa motor sokuqala isifunda sihlanganisa iSifundazwe a isinyathelo-phansi transformer hlobo. I edluliselwe kuleli cala isethelwe voltage okusezingeni eliphezulu emazombezombe futhi angabhekana ngayo sindisa esikhulu kakhulu. Uma sicabangela onobuhle enamandla ngalesosikhathi they are rectifiers.

Futhi, motor lokungeniswa ukuqala wesifunda kuhilela ukusetshenziswa resistors podstrochennogo hlobo. Kwezinye ukucupha, kungatholakala transceivers. Lezi amadivayisi zenzelwe ukunciphisa imvamisa iwashi motor lokungeniswa. Ngakho, kungashiwo iminyaka eminingi. Kenotrons amamodeli evame ukusetshenziswa stabilizers.

Single-isigaba motor temusho

Soft isiqalo lokungeniswa motor ngenxa ukuziqalela owodwa esigabeni kungenxa transformer is nginomdlandla. Okulandelayo it is yanikezwa edluliselwe, lapho ukuguqulwa okwenzeka ngayo. Iningi nokulungiswa yalolu hlobo anemisila Wegazi. Zisetshenziswa ikhodi kuphela, noma shayela-up. Ukuze uxhume Imiphumela i motor lokungeniswa isetshenziswa.

Ezinye ukushintshwa zidayiswa nabalawuli. Rectifiers kuthiwa efakwe ezisebenza ngqo. Sepharamitha embundwini sindisa onobuhle ingeqi 40 A. Ngakwelinye, emandla ato ezingeni ka 5-10 kW. Sepharamitha supply voltage amabanga kusuka 100 kuya 220 V Ngokwe degree of ukuvikelwa single phase ukuguqulwa zihlukile nomunye. Ezinye zazo basengozini umswakama nothuli, futhi lokhu kufanele kubhekwe ngaphambi kokuthenga.

Idivayisi ezimbili-isigaba onobuhle

Two-isigaba temusho kufanele ucabangele isibonelo jikelele onobuhle ukukhiqizwa. Lolu hlobo lwe-lokungeniswa motors (ezintathu okhombisa) Ukucaciswa zimi kanje: Amandla 5-15 kW, sindisa esiphezulu 40 A, ngesilinganiso voltage uvo 220 V. Le amahange asetshenziswa ukushintshwa ku eyinhloko emazombezombe. Leyo mikhumbi zisebenzisa Transformers, isinyathelo-phansi uhlobo. Kubalulekile futhi ukuqaphela ukuthi udlulisela asethwe nge stabilizers. Modulators lezi amadivayisi orthogonal ezifanelekayo. Ukulungiswa kuya resistors ezingajwayelekile kakhulu.

Ukuguqulwa uhlobo ezintathu okhombisa

isiqalo Soft of motor lokungeniswa usebenzisa ezintathu okhombisa temusho kuyashesha. Uma sikhuluma izici onobuhle, kubalulekile ukuphawula ukuthi idivayisi embundwini zingamelana umthwalo ngesilinganiso samakhilomitha 60 A amandla onobuhle eziningi ezingaphezu kuka 5 kW. A kusimo alamathuluzi ubhekwa ephansi ubuncane lokushisa embundwini. Frost akuvunyelwe nakancane ukuzisebenzisa. Modulators onobuhle uhlobo orthogonal efanelekayo.

ngokuvamile kungenzeka Dilators ukuhlangabezana ikhodi. Umngcele we-bandwidth zamanje bona awafani. Transceivers ngokuvamile efakwe temusho isigxobo. Transistors babe onobuhle ngokuyinhloko asetshenziswa broadband. I degree of ukuvikelwa temusho ezahlukene. Abaningi babo asesabi umswakama high, kodwa kulokhu, kuya kakhulu ngokuthi umakhi.

Starter onobuhle nge Rotor squirrel-yezinyoni

Nge squirrel yezinyoni lokungeniswa motors (ezintathu okhombisa) Ukucaciswa zimi kanje: Amandla 10 kW, sindisa obuyisilinganiselo 40, isibalo sabantu samanje uvo 220 V Iningi ukuziqalela transformers anemisila uhlobo phansi. Abanye ukucupha emakethe anemisila stabilizers. Kubalulekile futhi ukwazi ukuthi onobuhle nomthamo phezu 12 kW anemisila dinistorov ekhethekile.

Ukuze sinjalo, kunjalo ekahle okukhipha voltage. Wegazi e wonke amadivayisi usebenzise ikhodi. Nokho, thyristors afaneleka Semiconductor uhlobo kuphela. Ngokwesilinganiso, izinga lokushisa okungenani uyakwazi ukugcina kudivayisi 5 degrees. Ngokushesha uqale motor lokungeniswa nge squirrel yezinyoni ngokusebenzisa okukhipha oxhumana phezulu izindlu.

Izici models ukuqala ephezulu voltage imoto

Soft isiqalo lokungeniswa motor Kwenziwa ngokusebenzisa ephezulu voltage namandla Transformers. Lapha, kuphela nabalawuli kagesi asetshenziselwa ukulawula. Kenotrons ngqo setha ifrikhwensi. Transistors lezi onobuhle Site-bandwidth okusezingeni eliphezulu. Insulators amadivayisi, kunezinhlobo ezimbili. Ukuze uxhume ephezulu voltage motors asetshenziswa okukhipha oxhumana. Amamodeli nge dinistorov ezingavamile.

Yokuqala uchungechunge ABB

Yokuqala salolu chungechunge abhekwa evame kakhulu. Kulokhu, ukuqala injini kwenzeka ngenxa isigaba shift. Direct ukuguqulwa zamanje wenziwa ngokusebenzisa dinistorov. Ngu uhlobo edluliselwe onobuhle awafani. Amandla onobuhle ezisukela 4 kuya ku-12 kW. Ngakwelinye ihlangothi, voltage supply yisilinganiso sesifundo 220 V Amaphayiphu efakwe ikhodi uhlobo kuphela.

Uma sikhuluma modulators, high amandla onobuhle, zingabantu orthogonal. Kubalulekile futhi ukuqaphela ukuthi ama-transceivers wonke temusho kule isigxobo chungechunge. Ngokuvamile, imodeli ingatholakala kwi zokuthutha. Stabilizers kule divayisi ulahlekile. Uhlelo lokuvikela abafake uchungechunge IP-62, kanye nomswakama eliphezulu abawona esabe.

Kudivayisi ukuqala "Schneider"

Wathi ukuziqalela kuyahluka okokufaka voltage eliphezulu 200 V Kulokhu, injini qala-up ngokusebenzisa transformer amandla. Sidlulisele le imodeli isetshenziswa ne eyinhloko emazombezombe. Ngokusho imibhalo kudivayisi sindisa embundwini kulungiselelwa ngesikhathi A. ezingeni I Resistor 40 anemidwebo ukucushwa isethi postroechnyh futhi extender esetshenziswa ikhodi hlobo. Izinkinga ushintsho isigaba zedivayisi zenzeka kuyaqabukela. Ukuguqula modulator zamanje osebenza izinga. Speed isilawuli indlela motor kagesi hlobo. Dynistor nomkhiqizi unikezwe ukunwetshwa imodeli yalolu hlobo. Idivayisi zener kwi-intanethi.

Yokuqala imikhumbi

Amamodeli lwemikhumbi ayatholakala ngezikhundla ezahlukene. E uqalise. injini ngokusebenzisa transformer amandla. Uma sicabangela ushintsho kuhlelo ezimbili isigaba, bakwazi ukubhekana rectifiers. Modulators yena, ezibekwa njengoba orthogonal futhi beskondensatornogo hlobo. Resistors ngokuvamile asetshenziselwa trimmers. Ezintathu okhombisa ukuguqulwa temusho anemisila stabilizers. Ukushintsha imvamisa iwashi thyristors esetshenziswa. Kenotrons kulokhu asethwe nge umthamo eliphezulu.

onobuhle Modular for izindawo yenuzi

temusho Modular zinezikhathi okukhipha high voltage ipharamitha. E uqalise. injini ngokusebenzisa transformers ushiya phansi uhlobo. Ukuze onobuhle ababili okhombisa amandla analogue asetshenziswa kakhulu kuyaqabukela. Rectifiers udlulisela kuphela ukufakwa amadivaysi. Wegazi kukhona ukusetshenziswa hlobo yokudayela.

Degree yokuzivikela okunikelwe temusho Series SP-67. umswakama high nothuli amaphethini asesabi. Insulators amadivayisi itholakala kusukela amayunithi bathathu kuya kwabayisithupha. Ubukhulu kuhluka 4 kuya ku-10 kW. Umlawuli we indlela ijubane motor banayo uhlobo kagesi. Kubalulekile futhi ukuqaphela ukuthi amayunithi thyristor Semiconductor ezifakiwe nge oxhumana nabo.

kudivayisi Modular iziteshi lift

a temusho ezimbili isigaba asetshenziselwa iziteshi lift. Qala injini lokungeniswa usebenzisa ukuziqalela esimweni samanje kwenziwa ngokusebenza phansi transformer. sindisa yamanje lezi onobuhle ziyadingeka ukugcina at 40 A. enhancers for uninterruptible segezi zivame kakhulu ezisetshenziswa uhlobo ikhodi.

Transceivers zisetshenziselwa ngqo isigxobo. I modulators kulokhu kuyaqabukela esetshenziswa. Nokho, zikhona izinguquko ukuze nabalawuli. Resistors asetshenziswa abetifaniso ngombala, futhi uhlobo ishayela. Ukulungiswa kuya tube umphini emakethe azisenzeki. Nge ukuminyana kakhulu umsebenzi Transistor amabhlogo. Kubalulekile futhi ukuqaphela ukuthi onobuhle esetshenziswa insulators.

Izici amamodeli 60 A

Yokuqala 60 A iziteshi lift lehlukene tibalulekile kakhulu. isiqalo abushelelezi motor lokungeniswa kulokhu olunikezwa transformer amandla. I edluliselwe has onobuhle eziningi nge primary emazombezombe.

Ukuze operation evamile ukuziqalela esetshenziswa modulators orthogonal kuphela. Ngokushesha thyristor amayunithi kungabonwa uhlobo Semiconductor. IThrojani efaka isimeli seseva umthwalo bayakwazi ukumelana okukhulu. Amandla onobuhle emabangeni isilinganiso kusukela 10 kW.
