Yosalala kuyamba kupatsidwa ulemu galimoto: chipangizo, yadera

starters zofewa zilipo kwa Motors asynchronous mphamvu zosiyanasiyana. zitsanzo zambiri Cholinga makamaka pa kupereka mathamangitsidwe. Komabe, pali kasinthidwe kuti angapereke polekezera yosalala injini. Starters ntchito zambiri pa conveyors lapansi.

nawonso amene anaika pa malamba a conveyor. Pakuti mapampu, iwo ifeyo. Mfundo ntchito chitsanzo, potengera pang'onopang'ono kutsitsa panopa katundu chizindikiro. Kuti timvetse mwatsatanetsatane pa nkhani imeneyi, ganizirani chipangizo losavuta sitata.

Chiwembu muyezo sitata

Kusintha kupatsidwa ulemu galimoto poyambira dera chikuphatikizapo tsatane-pansi thiransifoma mtundu. The kulandirana Pankhaniyi amamasulidwa ku voteji mkulu kumulowetsa ndipo akhoza kulimbana ndi zimamuchulukira lalikulu kwambiri. Ngati tikambirana zitsanzo wamphamvu, ndiye iwo ali rectifiers.

Komanso kupatsidwa ulemu galimoto kuyambira dera zimaphatikizapo kugwiritsa ntchito resistors podstrochennogo mtundu. Mu ena masanjidwe, angapezeke transceivers. zipangizozi tinapangidwa kuchepetsa koloko pafupipafupi injini kupatsidwa ulemu. Choncho, ukhoza kwa zaka zambiri. Kenotrons zitsanzo za amagwiritsidwa ntchito stabilizers.

starters galimoto Single-gawo

Zofewa chiyambi kupatsidwa ulemu galimoto chifukwa lokhala ndi gawo sitata ndi chifukwa thiransifoma ndi imapatsidwa mphamvu. Chamawa iyo umaperekedwa kwa kulandirana, kumene kutembenuka chikuchitika. Ambiri mwa zosintha wa mtundu uwu zili ndi zochulukitsira. Iwo ntchito malamulo okha kapena oyimba-mmwamba. Kugwirizanitsa zotuluka ya galimoto kupatsidwa ulemu ntchito.

Ena zosintha amagulitsidwa ndi owongolera. Rectifiers amene anaika mwachindunji ntchito. Chizindikiro zitsanzo pakhomo zimamuchulukira si upambana 40 A. Poyankha, mphamvu zawo ndi pa mlingo wa 5-10 kW. Chizindikiro kotunga voteji ranges 100 mpaka 220 V. Malinga ndi digiri ya chitetezo cha kusinthidwa gawo limodzi zosiyana wina ndi mnzake. Ena a iwo ali pangozi chinyezi ndi fumbi, ndipo ayenera kuonedwa musanagule.

The chipangizo zitsanzo ziwiri gawo

Ziwiri gawo starters muyenera kuganizira chitsanzo cha zitsanzo ambiri kupanga. Mtundu wa Motors kupatsidwa ulemu (zitatu gawo) specifications ali motere: mphamvu ya 5-15 kW, pazipita zimamuchulukira 40 A, mlingo wa athandizira voteji a 220 V. anangula The ntchito ndi kuwasintha mu yaikulu kumulowetsa. The zitsanzo ntchito mtundu tiransifoma, sitepe-pansi. M'pofunikanso kukumbukira kuti yolandirana wa zakonzedwa ndi stabilizers. Modulators zipangizo amenewa abwino orthogonal. Zosintha kuti resistors ndi n'zochepa kwambiri.

Kusinthidwa kwa mtundu atatu gawo

Zofewa chiyambi cha galimoto kupatsidwa ulemu ntchito atatu gawo starters mofulumira. Ngati ife kulankhula za makhalidwe a zanyengo ndi ndikofunika kudziwa kuti chipangizo pakhomo chingathe kupirira katundu pa avareji 60 A mphamvu zitsanzo zambiri kuposa 5 kW. A sangathe mwa zipangizozi imatengedwa kukhala otsika osachepera kutentha pakhomo. Chisanu ndi koletsedwa ntchito. Modulators kwa zitsanzo abwino mtundu orthogonal.

Dilators zambiri kotheka kukumana ndi code. The chizindikiro cha bandiwifi panopa ali yosiyana. Transceivers zambiri anaika pa starters mtengo. Transistors ndi zitsanzo ali makamaka ntchito burodibandi. Mlingo wa chitetezo starters osiyana. Ambiri a iwo sali owopa chinyezi mkulu, koma mu nkhani iyi, zimadalira Mlengi.

Sitata kwa zitsanzo nawo gologolo-khola ozungulira

Ndi gologolo khola Motors kupatsidwa ulemu (zitatu gawo) specifications ali motere: Mphamvu 10 kW, pazipita zimamuchulukira ndi 40, mlingo wa athandizira panopa 220 V. ambiri sitata tiransifoma zili ndi mtundu pansi. Ena masanjidwe pa msika zili ndi stabilizers. M'pofunikanso kuona kuti zitsanzo ndi mphamvu zoposa 12 kW zili ndi dinistorov wapadera.

Pakuti olimba, iwo abwino linanena bungwe voteji. Zochulukitsira mu zipangizo zonse ntchito code. Komabe, thyristors ali oyenera okha michenga yopangira zida zamagetsi mtundu. Pafupifupi kutentha osachepera angathe kusunga chipangizo pa madigiri 5. Pomwepo kuyambitsa injini kupatsidwa ulemu ndi gologolo khola mwa ojambula linanena bungwe pa nyumba chapamwamba.

NKHANI zitsanzo chiyambi-mmwamba-voteji galimoto

Zofewa chiyambi kupatsidwa ulemu galimoto ikuchitika mwa mkulu-voteji tiransifoma mphamvu. Apa okha owongolera mu atomu ntchito kulamulira. Kenotrons mwachindunji anapereka pafupipafupi. Transistors kwa zitsanzo izi ali oyenera bandiwifi mkulu. Insulators mu zipangizo, pali awiri. Kulumikiza Motors mkulu-voteji ojambula linanena bungwe ntchito. Chitsanzo ndi dinistorov osowa.

Starters mndandanda ABB

Starters ija amaonedwa kuti ndi ofala kwambiri. Pankhaniyi, chiyambi cha injini kumachitika chifukwa gawo kosangalatsa. Direct kutembenuka masiku ano anachita dinistorov. Ndi mtundu wa zitsanzo kulandirana zosiyana. Mphamvu zitsanzo kuyambira 4 mpaka 12 kW. Nawonso kotunga voteji ndi avareji ya 220 V. mavavu anaika malamulo mtundu okha.

Ngati ife kulankhula za modulators, ndi zitsanzo mkulu mphamvu, ali orthogonal. M'pofunikanso kukumbukira kuti transceivers mu starters onse zino mtengo. Nthawi zambiri, chitsanzo angapezeke pa conveyors lapansi. Stabilizers ndi zipangizo kwina. dongosolo chitetezo iwo anaika angapo IP 62, ndi mkulu chinyezi iwo sali owopa.

Chipangizo poyambitsa "Schneider"

Anati sitata losiyana mkulu athandizira voteji a 200 V. Pankhaniyi, injini kuyamba-mmwamba mwa mphamvu thiransifoma. Zimayambitsa chitsanzo ichi ntchito ndi yaikulu kumulowetsa. Malinga ndi zolembedwa pa kolowera chipangizo zimamuchulukira pakhomo ndi pa mlingo A. The resistor 40 zithunzi kasinthidwe akonzedwa postroechnyh ndi extender ntchito malamulo mtundu. Mavuto ndi kusintha mu gawo chipangizo zimachitika kawirikawiri. Kutembenuza modulator panopa likukhudza khalidwe. Liwiro Mtsogoleri asynchronous galimoto mu atomu mtundu. Dynistor wopanga anapereka ndi patsogolo chitsanzo cha mtundu uwu. The chipangizo zener ndi olumikizidwa ku makina.

Starters kuti zombo

Chitsanzo cha ngalawa akupezeka ubongo osiyana. E unayamba. injini mwa mphamvu thiransifoma. Ngati tikulingalira ziwiri gawo zosintha, iwo zili ndi rectifiers. Modulators, amapatsidwa ngati orthogonal ndi mtundu beskondensatornogo. Resistors zambiri ntchito trimmers. Zitatu gawo starters kusinthidwa zili ndi stabilizers. Kusintha koloko pafupipafupi thyristors ntchito. Kenotrons Pankhaniyi zakonzedwa ndi mphamvu yapamwamba.

zitsanzo yodziyimira payokha kwa maofesi nyukiliya

starters yodziyimira payokha yodziwika ndi mkulu linanena bungwe voteji chizindikiro. E unayamba. injini kudzera tiransifoma mwatsatane pansi mtundu. Pakuti zitsanzo ziwiri gawo mphamvu analogues ntchito kwambiri kawirikawiri. Rectifiers yolandirana okha anaika mu zipangizo. Zochulukitsira ntchito oyimba-mmwamba mtundu.

Digiri ya chitetezo kwa starters Series SP-67. Mkulu chinyezi ndi fumbi dongosolo si mantha. Insulators mu zipangizo ali pakati pa atatu ndi asanu mayunitsi. Makulidwe zimasiyanasiyana 4 10 kW. The yang'anira wa asynchronous galimoto liwiro ali ndi mtundu mu atomu. M'pofunikanso kukumbukira kuti mayunitsi thyristor michenga yopangira zida zamagetsi amene anaika ndi anzanu.

Yodziyimira payokha chipangizo za malo Nyamulani

ndi starters ziwiri gawo ntchito za malo Nyamulani. Kuyambitsa injini kupatsidwa ulemu ntchito sitata zinalili pano anachita ndi ntchito pansi thiransifoma. zimamuchulukira Current zitsanzo izi ayenera kusunga pa 40 A. Enhancers kwa katundu uninterruptible ulamuliro zambiri ntchito mtundu wa code.

Transceivers ntchito mwachindunji mtengo. The modulators mu nkhani iyi kawirikawiri ntchito. Komabe, pali zosintha kuti owongolera lapansi. Resistors ntchito monga zitsanzo kokha, ndipo mtundu zimachitika. Zosintha ku valavu chubu pa msika sanalembedwepo. Ndi kuchulukana kwambiri ntchito transistor atilakwira. M'pofunikanso kukumbukira kuti zitsanzo za ntchito insulators.

Makhalidwe Chitsanzo 60

Starters 60 za malo Nyamulani abwino. Yosalala chiyambi cha mota kupatsidwa ulemu Pankhaniyi operekedwa ndi mphamvu thiransifoma. The kulandirana ali zitsanzo zambiri ndi yaikulu kumulowetsa.

Ntchito yachibadwa ya sitata ntchito modulators yekha orthogonal. Pomwepo thyristor mayunitsi Tingaone mtundu michenga yopangira zida zamagetsi. Pakhomo katundu amatha kupirira kwambiri. Mphamvu zitsanzo pa ranges pafupifupi 10 kW.
