I-Electromagnet ngaphansi kwe-hood

Isihloko salesi sihloko sibhekisela ezintweni ezincane nezibonakala zingabonakali kumjikelezo kagesi wezimoto, ezibizwa ngokuthi ama-electric relays. Umsebenzi wabo oyinhloko ukuqinisekisa ukunikezwa kukagesi okulungile kusuka ebhethri kuya kumamukeli, ngenxa yokuthi akuzona kuphela izimpawu zokujika, ukucwiliswa, izibani eziphezulu nezibani zenkungu, kodwa namafasitela kagesi kanye nokukhiya okuphakathi.

Ngezikhali ezinyakazayo

Umgomo wokusebenza kokudluliselwa kukagesi osetshenziswa ezimotweni ungaqhathaniswa nozibuthe owaziwayo, ngokwesibonelo, ezifundweni ze-physics. Ekusebenzeni, kubonakala kanje: ngemva kokuvula idivayisi eyamukelayo, okwamanje iqala ukugeleza ngokusebenzisa i-relay winding. Ngokulandelayo, inkambu kazibuthe edalwe kumongo wayo we-ferromagnetic iheha ipuleti elikhethekile eligudlukayo, elibizwa ngochwepheshe ngokuthi ihange. Lesi sakamuva sinokuxhumana, okuthi, kanye nepuleti, sikhangwe kothintana naye wesibili (olungisiwe). Uma bobabili abathintwayo bevaliwe, i-current ingageleza isuka kubhethri iye kumamukeli. Kodwa-ke, lapho idivayisi eyamukelayo ivaliwe, i-current ngokusebenzisa i-electromagnet winding iyayeka ukuhamba. Ngenxa yalokho, i-armature ephathekayo idonselwa emuva yintwasahlobo bese oxhumana nabo bavuleka.

Mncane esikhundleni sokujiya

Lapho ujwayelana nesimiso sokusebenza kwama-relay kagesi, kufanelekile ukubuza mayelana nokusebenza kwawo okusebenzayo. Kubalulekile ukwazi ukuthi kungenxa yalezi zakhi ezicashile ukuthi izintambo zikagesi ezincane zingasetshenziswa ukuqhuba ugesi, kuhlanganise nokugeleza okuphezulu. Kulula ukucabanga ukuthi uma singabandakanyi ama-relay kagesi, kuzodingeka sisebenzise izintambo eziwugqinsi, i.e. ngokomsebenzi: enengxenye enkulu. Ngaphezu kwalokho, ezimweni eziningi lokhu kuyodingeka kwenziwe ebangeni elikhulu uma kuqhathaniswa, ebhethrini lolayini - iswishi somamukeli - ibhokisi le-fuse - umamukeli. Ngaphezu kwalokho, ibanga phakathi kwenkinobho ethile nomamukeli lizoba nobunzima obengeziwe. Lesi sakamuva, okuyinto, yiqiniso, iningi labasebenzisi bezimoto abazi ngakho, kwezinye izimo lize lifinyelele kumamitha amaningana. Izinyanda eziwugqinsi zezintambo zikagesi zizothatha indawo enkulu kangangokuthi kungaba nzima ukuzibeka, isibonelo, ngaphansi kwe-hood (ezimotweni zanamuhla lesi sikhala sesivele sigcwele ngokuphelele). Enye inkinga kuzoba yizindleko eziphezulu zokukhiqiza izintambo ezinjalo.

izindlela ezintathu

Yiziphi izintambo zikagesi ezisetshenziswa ezimotweni? Ngokuvamile, zingahlukaniswa zibe izinhlobo ezintathu. Isikhathi esiningi sihlangana nama-relay nalokhu okuthiwa. vula othintana nabo. Igama lalokhu kwakamuva livela esimisweni sesenzo sazo, esibilisa kuze kube sekuxhumaniseni othintana nabo lapho i-current igeleza ekujikeni kukazibuthe kagesi. I-relay ingatholakala, phakathi kwezinye izinto, kumasekhethi azo zonke izinhlobo zokukhanya (i-high beam, i-beam ephansi nenkungu), kanye nokuvula uphondo nokushisa iwindi elingemuva (ngokuzikhethela futhi i-windshield). Uhlobo lwesibili lwe-relay kagesi, okuthiwa othintana nabo abavaliwe, lusetshenziselwa ukufakwa kwe-alamu kanye ne-immobilizer. Ngokungafani nozakwabo abavulekile, ukuwavula nokwenza isamukeli esithile sisebenze kubangela ukugeleza kwamanje. Ngokulandelayo, ama-relay ohlobo lwesithathu afakwa kumasekethe ekhiya emaphakathi noma amafasitela wamandla. "Azivuliwe" futhi "azivaliwe". Lawa ma-relay agxilile othintana nabo abaphezulu nabaphansi, futhi i-jumper ehamba phakathi kwabo inesibopho sokushintsha i-voltage ehlinzekwa kumamukeli.

Qaphela… amasekethe amafushane!

Uma kuqhathaniswa nezinye izingxenye eziningi zezimoto, ukudluliselwa kukagesi kungamadivayisi anokwethenjelwa. Nokho, kwezinye izimo nawo alimale. Yiziphi izimbangela ezivame kakhulu zokwehluleka kwe-relay? Zingalimala kokubili ngomshini, isibonelo, ngemva kwezinhlobo ezihlukahlukene zokushaqeka (ukushayisana kwemigwaqo, njll.), kanye nangogesi (amasekhethi amafushane kulayini othize wokwamukela ibhethri). I-relay kagesi eyonakele kufanele ishintshwe ngokushesha. Nokho, kunezindaba ezinhle: lo msebenzi akufanele wethule noma yibuphi ubunzima obuthile. Nokho, qaphela! Lapho ushintsha, qiniseka ukuthi ubuyisela i-relay eyonakele ngolunye lohlobo olufanayo, ngamanye amazwi: ivulekile-ivuliwe, ivaliwe-ivaliwe, futhi ilungisiwe. Nokho, kubaluleke kakhulu ukunaka iqiniso lokuthi okuthiwa. Imilenze ye-plug-in yokudluliselwa kwezinhlobo ezahlukene ingaba nendawo efanayo futhi kulokhu ingena kumasokhethi ahlukene. Ngenxa yalokho, singakwazi ukufaka kalula i-relay ku-socket, kodwa ngemva kokuvula amandla, ukumangala okungajabulisi kakhulu kusilindele ngendlela ... isifunda esifushane ekufakweni kukagesi kwesamukeli esithile. Isimo sibi nakakhulu nalokhu okuthiwa. Amadivayisi anemisebenzi eminingi (kuhlanganise nalawo anesici sokulibaziseka). Ukuze ugweme ukuwohloka okungalindelekile nokubizayo, indawo yokudlulisela edluliswayo eyonakele kufanele kushintshwe ishabhu lochwepheshe elihlome ngemishini ekhethekile yokuxilonga.
