Edluliselwe karhulumente Solid. Siseko ukusebenza. uqhagamshelo

Edluliselwe karhulumente isetyenziswe ngokubanzi eqinileyo ezifumaneka kolu shishino. Apha isetyenziswa zokudalwa izixhobo kufuneka ube neempawu ezincinane uze ube oluthembekileyo. Ufinyezo Cyrillic ukhangela TTP, kwaye Latin SSR. Njengoko abaphumeleli eziphambili zezi zixhobo kuthiwa ngexabiso. Kodwa ngokwesakhelo kweli nqaku, siza kuthetha kuphela malunga nemisebenzi kunye neenzuzo relay karhulumente okuqinileyo.

Siseko ukusebenza kunye nokwakhiwa

Makhe sijonge lokuqala kwi relay isebenza njani eqhelekileyo. It is a isixhobo apho kukho abafowunelwa kunye coil yolawulo. Ukuze isixhobo ukusebenza, kufuneka ukuba xi, esebenzisa apho ziya kuphenjelelwa. Oko kuya kubangela umfowunelwa kuvulwa okanye ivalwe xa ikhala phezu spool. edluliselwe karhulumente Solid isebenza ngendlela efanayo. Kuphela apha, endaweni abafowunelwa kusetyenziswa izixhobo semiconductor. Avamise kakhulu triacs, thyristors (nokusebenzisa i ifildi current) kunye transistors (kuba DC). Kwakhona kwi relay eziqinileyo-karhulumente isetyenziswa bodwa galvanic phakathi abafowunelwa amandla jiko. Oku kuphunyezwa ngenxa ubukho kwigalelo optocoupler. Ukuba yenziwe ukusebenza ngokusebenzisa thyristors kunye triacs, ngoko esiya kuthi, ukuba le into eqinileyo-karhulumente bahlabe AC.

uthelekiso

Ngokubanzi, transistor ngalinye iqhosha angamelwa njenge irileyi karhulumente esiqinileyo. Masikhumbule isakhiwo uninzi boluvo sindululo okanye ukhanyiso. Ba enyanisweni okudalwe ngokwentando siseko apho kwi relay eqhelekileyo onikeza ombane kule transistor na. I-coil kunye semiconductor element njengoko kumfowunelwa. Ngokuphathelele ukusetyenziswa Triac kunye thyristors, bakwazi ukuqhuba ngoku kwiindlela zombini (oko kukuthi ingafikeleleki ukuya transistor). Ukuba siqhubeka ngakumbi uthelekiso yethu, kubalulekile ukukhumbula ukuba SSRs zabemi kwaye ezilahlekileyo namandla kakhulu ngaphantsi ngexesha lokusebenza. Kananjalo sibe ubungakanani elincinane, ngesantya esiphezulu, ubomi obude cwaka ngokupheleleyo. Ke, phezu kwazo zonke iingenelo, ukuba kuthi ukuba siza kukwazi swi baphinde eqhelekileyo kwixa elizayo akakwazi.

umahluko intraspecific

Ukwahlula Solid State edluliselwe:

1. phase-amathathu bahambe imigama zangoku kwi kuluhlu ukususela amps-10 ukuya 120 kanye ngezigaba-3.
2. Umva. Izixhobo semiconductor ukuba enze licwecwe ziguquka imisinga DC ne AC. Ngokutsho umsebenzi wayo ophambili oononye-kwisigaba esinye irileyi. Mfuneko ukuba ube wesiphaluka yolawulo esibonelela ukhuseleko nxamnye kusebenze bobuxoki. relay uguqula luphawulwa umsebenzi izigaba ezithathu, kwaye nobomi inkonzo ende. Oku Bulelani ukuba indlela yolawulo ophezulu ezikumgangatho bodwa, nto leyo zibonelelwa ngokokwakheka olu hlobo yesixhobo. Xa usebenzisa idatha isixhobo akukho ingxolo yiacoustic, abalozayo, isusa nxa.
3. Isigaba esinye inikeza commutation ngoku yokuwela yayo zero. Isigaba Single edluliselwe karhulumente eqinileyo osebenza uluhlu amperes-10 ukuya 500. Ngaba ulawulwe ngeendlela ezine.

izicelo

Solid baphinde karhulumente asetyenziswa apho kuyimfuneko ukuba zilandele ngqo le mgaqo ukufaka ndilibale ngayo. Thelekisa, khangela umzekelo. Kodwa ke, ngaphambi koko, makhe sihlolisise Ngaphandle imiyalelo abafowunelwa njengesiqhelo: ndiyazicoca nkqu umenzi lithethelela ukuba amawaka ambalwa kwiisekethe mijikelo.

Kodwa ngoku ngenxa umzekelo. Kwishishini unalo umatshini apho kwezivalo solenoid. Amandla kubo - 24VDC 2A. Bona enxulumene ngaxeshanye. Off on / off malunga kanye ngomzuzwana. Power ikhutshwa ngokusebenzisa relay. Nokuba kunjalo uyakwazi ukumelana amps 10 umthwalo zokuqala, ngoko watshintsha nyanga nganye okanye ezimbini kuya kufuneka. Nangona edluliselwe karhulumente eqinileyo kuyilibala ngayo iminyaka. Ngoxa ekuqhubeni kuhlolwa zobugcisa asifikanga irhoxisiwe. Kule nkalo, kungakuhle ukuba baqwalasele iingcebiso ezifunyenwe umenzi namaxwebhu akhaphayo.

Ubungqina obubonakalayo buxela

Ukuba nabo rhoqo abakwazi ukumelana noxanduva lwabo, zizitshise ngathi isibane, ngoko oku isiphakamiso kakhulu ukusetyenziswa. SSRs uyakwazi ukunika ukusebenza oluthembekileyo. Banako lula ukuphatha isenza i kwemithwalo ezenza. Kwakhona, ukuba ufuna ukuqinisekisa ukuba abafowunelwa musa ziyaxinga, okanye kukho umda engqongqo ngobukhulu - baphinde esiluqilima-karhulumente ukuba aid yakho.

Zeziphi ezi ntlobo zahlukeneyo relay eqinileyo-karhulumente?

Zahlula kwisixhobo, kwakunye siseko ukusebenza. Kuba lula ukuqonda, Mna ndicebisa ngokuhlelwa kulandelayo:

• Ngokuxhomekeka kuhlobo ombane wolawulo:

1. Constant (ezahlukene).
2. Variable.

• Ngokuxhomekeka kuhlobo ombane ukuguqukela:

1. Nesebenzayo.
2. Njalo.

• Kungakhathaliseki ukuba inani ngokwezigaba nokuxuba ombane:

1. Single.
2. Ezintathu. Apha kukho ithuba kwisahlulo ngokusekelwe ukuba okanye hayi umva.

• On zempawu zoyilo (apho ufakelo yenziwa):

1. Phezu komhlaba.
2. Din-rail engathethekiyo.

Ukukhetha olu gqatso karhulumente eqinileyo

Kufuneka kuqatshelwe iimpawu ezithile. Umzekelo, ukuba baphinde zingenakukwazi ngaphandle kobunzima ukumelana ukucima kombane elifutshane, ubukhulu apho kuya kuba 150% okanye 200% yexabiso rated. Ukuba yonke into ngokuchanekileyo, ngoko ukucoca abafowunelwa nga ikhe ibekwe kuzo zonke iimeko. Ngenxa relay eziqinileyo-umbuso ongayi kunikwa ithuba. Ngoko ke, ukuba index ukuba ngaphezu kwe-150%, kukhuselekile ulahle kude isixhobo. Ngoko ke, ukuba umthwalo resistive kufuneka kubekho ubonelelo rated yangoku ngokuphindwe 2-4. Ukuba relay eziqinileyo-karhulumente iza kusetyenziswa ukubaleka Motors olungenangqamaniso, eli nani kuya kufuneka ukuba kunyuka izihlandlo 6-10. Le uSt, nangona yenza ukukhetha izinto ezibiza kakhulu ngexesha elinye kuqinisekisa ubomi elide idivaysi iqhagamshela kwisixhobo.

Yongeza-ons ukuba isebenze kakuhle

Xa unxulumano kunye nokwakhiwa umthwalo ezenza ukuba zihambise neengxaki ezithile. Ngenxa yoko, xa usebenza abaguquli, iintsimbi zombane, kunye jiko Imagnethi yomhlaba kunye nezixhobo ezifana kufuneka ukufana RC-beesekethe ukuba ukunciphisa impembelelo EMF umva. Kwakhona kuya kunciphisa inductance umthwalo ngokubanzi, yaye zazi- eziqinileyo-karhulumente kuya kuba lula ukusebenza.

Mfutshane protection circuit

Abavelisi kule meko Kucetyiswa ukuba basebenzise izixhobo zokhuseleko ezizodwa, leyo zaphuhliswa ngenxa izixhobo okuqinileyo-karhulumente. Nantsi yokuhlelwa kwazo;

1. Gr - iifyuzi, ezisebenzela phezu uluhlu olupheleleyo imisinga zokusebenza. Zisetyenziswa ukukhusela izinto semiconductor. Kuthathwa ngokukhawuleza kakhulu.
2. GS - asebenza phezu uluhlu olupheleleyo imisinga zokusebenza. Isetyenziswa xa emgceni lifumana umthwalo banda, kwakunye ukhuselo izixhobo semiconductor.
3. ar - iifyuzi esebenza phezu uluhlu olupheleleyo imisinga ukusebenza. Isetyenziswa ukukhusela izinto semiconductor evela kwisiphaluka elifutshane.

Kufuneka kuqatshelwe ukuba iifyuzi ayabiza kakhulu. Ngoko ke amaza (class B) zisetyenziswa njengenye.

Ndithenga phi na?

Thenga Solid Ukubalisa State AC kwi Kwivenkile ye-elektroniki elikufutshane. Kodwa usebenza, njengoko umgaqo, kwabo iimeko apho indawo ahlala kuyo umfundi - isixeko esikhulu. Ukuba akunjalo, kusenokuba kuhle ukuba usebenzise iinkonzo iivenkile online. Zisoloko zifumaneka busiwa kumamkeli isixa esithile, okanye simahla.

Yaye yintoni na enokuthethwa ngqo malunga iindleko zeziphi na gqatso karhulumente esiqinileyo? Ixabiso ezi zixhobo isusela ukusuka 600 ukuya engange amawaka aliqela.

kokuxhuma imthetho

Xa esi senzo, akukho nto kunzima. Ngoko ke, ukuba icebo sisebenze igalelo ulungise kufuneka asebenzise ombane yolawulo. Makhe sithethe ngeempawu kule nkqubo:

1. Imixube ezinqwenelekayo ukwenza ngendlela helical kwaye hayi ngelotha.
2. Ukuze siphephe le meko kunye nomonakalo kwifowuni kuyimfuneko ukukhangela ukungabikho uthuli, izinto ezibengezelayo indalo.
3. Zama ukuba benze konke okusemandleni ukuze ukuphepha iimpembelelo eziyingozi lwangaphandle kwi yikhabhinethi (kokubini ngexesha intsebenziswano xa ivulwa off).
4. Musa ukuyichukumisa iswitshi xa isebenza ukuphepha kokuba itshiswe. Kwakhona, khangela ukuba ifowuni ayikho kufutshane nezinto ezinokutsha.
5. Xa uqhagamshele, qiniseka ukuba ekunene isenza i imidibaniso.
6. Ukuba ifowuni ngethuba osebenza itshiswe ngaphezu kweqondo lama-60, kufuneka ukuba ufumane kwiradiyetha okupholisa kuye.
7. Kufuneka ilunyukelwe kakhulu into yokuba nayiphi na short-circuit kwisixhobo kwimveliso. Kwimeko esahlukileyo, nje lutshitshe.

ulawulo ngqo relay esiluqilima-umbuso kwenziwa umxokelelwane, apho embodiments ezahlukeneyo zikhona. Umfo kwigalelo plus.

isiphelo

Siye ngokutsha relay eqinileyo karhulumente, umthetho-siseko ukusebenza, ulawulo, ukhuselo iintlobo - konke nto. Kakade ke, oku akwanelanga ngokuzimeleyo ukwenza ukufakelwa esi sixhobo, kwiimeko ezininzi.
