Yintoni rheostat? Types and Functions

Abantu oxhulumene ngandlel 'ithile kunye nokwakheka, elektroniki, unomathotholo, badla ngokujongana into efana rheostat. Kodwa abanye zange abe nofifi ngayo. Eli nqaku liza kujongana yintoni a rheostat, yaye yintoni na ke ukuba.

Inkcazo kunye Types

Ngoko ke, lo rheostat - isixhobo eliquka resistors eziliqela kunye nezixhobo ngazo eyayilawula ukungawi zonke resistors ifakiwe.

Iindidi dimmers zixhomekeke injongo yabo:

• Kukho mawahlaziyeke rheostats zangoku, ezo ukuqalisa motor AC okanye DC.
• Zokulinganisa resistor kuyafuneka ukuba ukuqala isantya iinjini zombane kunye zangoku rhoqo kunye ummiselo wayo.
• Le zokulinganisa okanye umthwalo resistor - izixhobo wombane ukufunxeka lwamandla kwi ummiselo wacela wenkunkuma okanye umthwalo sokuhlolwa generator.
• Rheostat excitation ezifunekayo ukuze kulawulwe ukubolekisana zangoku kwi engathi ekubeni oomatshini zombane AC okanye ngoku ngqo.

Material and Ukupholisa

Enye iimpawu ezibonakalisa isiqalelo kuyilo lo nesixhobo equka rheostat. Kwaye ngenxa yesi sizathu angohlulwa dimmers kwi yodongwe, elulwelo, intsimbi kunye namalahle. Umbane kwi resistors aguqulwa abe bubushushu, ekufuneka zivela kubo. Ngoko ke, lo rheostat na umoya kunye ulwelo okupholisa. Uhlobo lwesibini inokuba amanzi okanye oyile. uhlobo Air asetyenziselwe nayiphi rheostat yokwakha. Le nto ilulwelo kuphela metal, kuba resistors zabo ulwelo iimeko okanye ukuntywiliselwa ngokupheleleyo kuyo. Kuyimfuneko kule meko ukwazi ukuba amanzi asetyenziswa sokwehlisa, kwaye nokuba ngokwayo kufuneka lupholile okanye umoya, okanye ulwelo.

rheostats metal

Yintoni rheostat ngentsimbi? Lo nto ukuba uhlobo olupholisa umoya. Ezo rheostats zixhaphakileyo, ukusukela ukuba lula lungqanyaniswe ezahlukeneyo kweemeko zokusebenza. Oku kusebenza kuzo zombini kwiimpawu thermal kunye zombane, kunye parameters design. Ukuba ingenziwa na uhlobo izame okanye rhoqo utshintsho ukumelana.

I iswitshi flat. It has a umfowunelwa ezinokususwa ukuba umba kwi abafowunelwa ezisisigxina indiza. Ezo labafowunelwa musa ukuhamba, enziwe ngohlobo ngezikhonkwane ukuba tyaba iintloko zezindlu okanye uhlobo hemispherical ngohlobo amacwecwe okanye amavili emoto, ezo zilahlwa kwi arc kumqolo omnye okanye emibini. Le umfowunelwa enambuzelayo kuthiwa ibrashi. Oko kuvaleka yi lempumelelo okanye udidi ukuphunyezwa.

Kodwa kukho iyantlukwano kule self-kuqiniswe kunye nesamoustanavlivayuschiysya. Le ndlela yokugqibela zedizayini lula, kodwa, njengoko kudla umfowunelwa yaphulwe, akukhuselekanga ukuyisebenzisa. I self-wokulungelelanisa qha ihambe ubonelela ngomlinganiselo eyimfuneko ngokucindezela ekusebenzeni athembeke. Kungenxa yoko le nto kusifikeleyo oku hlobo luqhelekileyo.

Iingenelo neengozi eyenziwayo flat

Izinto eziluncedo yeflethi-uhlobo itshintshela ziquka uyilo elula, ubungakanani encinane inani elikhulu amanyathelo, ixabiso eliphantsi, baphinde, zokuqhawula nokukhusela kwisekethe yolawulo.

Phakathi kubakho iingxaki ezimbalwa waphawula amandla ziguquka asanelanga, umthamo omncinane utshintshayo. Kwaye ngenxa ungquzulwano ukunyibilika phantsi ngokukhawuleza iya ibrashi.

Ukupholisa oyile

Metal rheostats umthamo ubushushu uhlobo oyile-okupholisa kwanda kunye nexesha ubushushu ngenxa neoli elungileyo ubushushu conductivity. Oku kwenza kube lula ukwandisa umthwalo ukusebenza elifutshane elide kunye nokunciphisa ukusetyenziswa eziphathekayo kunye ubungakanani resistors rheostat.

Imiba antywiliselwa eolini, kufuneka ube indawo umphezulu enkulu ukuqinisekisa ukuba ukudluliswa elungileyo ubushushu. Ukuba ivaliwe-uhlobo resistor, yenza akukho ingqiqo ukuba ndibhaptize ibe ioli. ukuntywiliselwa ezingeyomfuneko unika abafowunelwa nokhuselo kunye resistors kwimiphumo ngeemeko zokusingqongileyo. Abafownelwa oli ngenxa yokusindwa lwabasenzi abandisiweyo. Le abaxhamla kule hlobo dimmers. Ngenxa ukuthambisa ajikeleze mhlawumbi ngakumbi sikuxinile kumfowunelwa. Kodwa kukho kuneengxaki. Oku kubonakalisa ukwanda kwengozi iingozi zomlilo kunye nongcoliseko yesakhiwo.

Le rheostat ukuze kudityaniswa kwisiphaluka resistor bume okanye potentiometer. Oku inika hlengahlengiso kakuhle bokuxhathisa kwaye, ngenxa yoko, ulawulo amandla ngoku kunye ombane kwisekethe. Ngokufuthi zisetyenziswa neelabhoratri.

ballasts rheostats

Rheostat ukuba utshintsho inyathelo resistance, enziwe resistors kunye isixhobo isenza i ebandakanya, ke, ukususela abafowunelwa esisigxina, umfowunelwa sliding. Apha kukho i drive.

Qala dimmers zolawulo ezi izibonda ezo armature, oludityaniswe abafowunelwa ezisisigxina. Qha ezinokususwa avale, waluvula kwinqanaba lovukelo, kwakunye nezinye iziphaluka apho balawulwa ngokungqinelana rheostat. Actuator rheostat inokuba mafutha okanye ngesandla. Yintoni leyo? Rheostat olu hlobo yasasazwa. Kodwa ezingalunganga kule Uyilo isekhona. Eli linani elikhulu iingcingo ukuba indibano neenxalenye ukwenzela ukulungiswa. Ingakumbi abaninzi kubo excitation rheostat esinamanani amakhulu amanyathelo.

Rheostat ezizalisa ngamafutha, iqulunqwe isixhobo ziguquka kunye packs resistor elungiselwe kwitanki enincokola eolini. Iipakethi luqulathe izinto ezenziwe ngentsimbi zombane. Bona apha ngaphezulu etankini.

Icebo usuke baneembono ahlangene igubu kunye luqhotyoshelwe noko nge izahlulo kumphezulu zezindlu abaqhagamshelwe ngokutsho kohlelo. nabo Fixed, abaqhagamshelwe izinto resistor zifakwe kwi-kaloliwe esisigxina. Xa axis igubu yokubolekisana drive okanye flywheel, ezo iindawo bridging esisigxina abafowunelwa, abafowunelwa movable ukuba. Oku lutshintsha uxhathiso kwisekethe.

Le ngasentla ukucacisa ngokupheleleyo umbuzo, yintoni a rheostat. Njengoko ubona, oku into ebaluleke kakhulu, nto leyo sisetyenziswa ngokubanzi ezahlukeneyo iziphaluka zombane.
