Ukuvula Ukusebenza Nokuphepha: Amandla Okudlulisa Okushisayo kanyeI-Thermal Overload Relays
Esimeni esiguqukayo njalo sobunjiniyela bezimboni kanye nobunjiniyela bukagesi, ukuqinisekisa ukuphepha nokusebenza kahle kwemishini kubaluleke kakhulu. Faka amaqhawe angaculwanga omhlaba kagesi: ama-thermal relay kanye ne-thermal overload relay. Le mishini, nakuba ivame ukunganakwa, idlala indima ebalulekile ekuvikeleni izinjini nezinye izinto zikagesi ekulimaleni ngenxa yokushisa ngokweqile. Kule bhulogi, sizocubungula ukubaluleka kwalezi zingxenye, izimiso zazo zokusebenza, nokuthi kungani zibalulekile ekusetshenzisweni kwezimboni zesimanje.
Ukuqonda ama-Thermal Relays kanye ne-Thermal Overload Relays
Emgogodleni wabo, ama-thermal relays kanye ne-thermal overload relays yakhelwe ukuvikela amasekhethi kagesi kusukela kumanje ngokweqile okungaholela ekushiseni ngokweqile nasekulimaleni okungaba khona. I-thermal relay iyithuluzi elivikelayo elisebenza ngokusekelwe ekushiseni okukhiqizwa amandla amanje agelezayo kuwo. Uma i-current idlula ileveli enqunywe kusengaphambili, ukushisa okukhiqizwa kubangela ukuthi i-relay ihambe, ngaleyo ndlela iphazamise ukujikeleza futhi ivimbele ukulimala okwengeziwe.
Ngakolunye uhlangothi, i-thermal overload relay wuhlobo oluthile lwe-thermal relay olusetshenziswa ngokuyinhloko ukuvikela amamotho ekushiseni ngokweqile. Ama-motor angamahhashi okusebenza emishini yezimboni, futhi ukusebenza kwawo okuqhubekayo kwesinye isikhathi kungaholela ekwakhiweni kokushisa ngokweqile. I-thermal overload relay iqapha izinga lokushisa lemoto futhi igibele isekethe uma izinga lokushisa lidlula umkhawulo ophephile. Lokhu akuvimbeli kuphela ukulimala kwemoto kodwa futhi kuqinisekisa ukuphepha kwalo lonke uhlelo.
Isimiso Esisebenzayo: I-Symphony Yokushisa Nemishini
Ukusebenza kwama-thermal relay kanye ne-thermal overload relays kuwukuhlangana okuthakazelisayo kokushisa nokunyakaza kwemishini. Lawa madivayisi ngokuvamile aqukethe umugqa we-bimetallic, owakhiwa izinsimbi ezimbili ezihlukene ezinama-coefficients ahlukile wokunwetshwa kwe-thermal. Uma i-current igeleza ku-relay, umugqa we-bimetallic uyashisa futhi uyagoba ngenxa yamazinga ahlukene okunweba ezinsimbi. Lesi senzo sokugoba siqala indlela yomshini evula isifunda, ngaleyo ndlela iphazamise ukugeleza kwamandla.
Endabeni yokudluliswa kwe-thermal overload, umugqa we-bimetallic uvame ukuhlanganiswa nesici se-heater esithintana ngqo nenjini. Njengoba injini isebenza, i-elementi ye-heater iyafudumala, okwenza ukuthi umugqa we-bimetallic ugobe. Uma izinga lokushisa lemoto likhuphuka ngaphezu komkhawulo ophephile, umucu uyagoba ngokwanele ukuze ukhubekise ukudluliselwa, kunqamule ukunikezwa kwamandla enjini. Le ndlela elula kodwa ephumelelayo iqinisekisa ukuthi injini ivikelekile ekushiseni ngokweqile, ngaleyo ndlela yandise isikhathi sayo sokuphila futhi yehlise nezindleko zokuyilungisa.
Kungani ama-Thermal Relays kanye ne-Thermal Overload Relays Ibaluleke kakhulu
Ukubaluleka kokudluliswa kwe-thermal kanye ne-thermal overload relays akukwazi ukweqiwa. Ezilungiselelweni zezimboni, lapho imishini isebenza ngokuqhubekayo futhi ngokuvamile ngaphansi kwemithwalo esindayo, ubungozi bokushisa ngokweqile buhlala bukhona. Ngaphandle kwalezi zinsimbi zokuzivikela, izinjini nezinye izinto zikagesi zingaba lula ekulimaleni, okuholela ekulungiseni okubizayo nasekuphelelweni yisikhathi. Ngokuhlanganisa ama-thermal relay kanye nama-thermal overload relays kumasistimu azo, izimboni zingaqinisekisa impilo ende nokuthembeka kwemishini yazo.
Ngaphezu kwalokho, lawa madivayisi aneqhaza ekuphepheni okuphelele emsebenzini. Ukushisa ngokweqile akukwazi nje ukulimaza imishini kodwa futhi kubangela ingozi yomlilo. Ama-thermal relay kanye ne-thermal overload relays kusebenza njengomugqa wokuqala wokuzivikela, ukuvimbela ukushisa ngokweqile kanye nokunciphisa ingozi yomlilo. Lokhu kubaluleke kakhulu ezimbonini lapho izinto ezivuthayo zikhona, futhi ukuphepha kuyinto ehamba phambili.
Ukukhetha i-Thermal Relay efanele kanye ne-Thermal Overload Relay
Ukukhetha i-thermal relay efanelekile noma i-thermal overload relay yohlelo lwakho lokusebenza kubalulekile ekuqinisekiseni ukusebenza nokuvikelwa okuphelele. Izinto okufanele zicatshangelwe zihlanganisa isilinganiso samanje, uhlobo lwemoto noma okokusebenza okuvikelwe, kanye nendawo yokusebenza. Kubalulekile futhi ukukhetha i-relay enekilasi lohambo elilungile, elinquma ukuthi i-relay izosabela ngokushesha kangakanani esimweni sokugcwala kakhulu.
Abakhiqizi abaningi abahlonishwayo banikeza izinhlobonhlobo zokudlulisa okushisayo kanye nokulayishwa kwe-thermal overload, ngayinye yakhelwe ukuhlangabezana nezidingo ezithile. Ukutshala imali ekusakazweni kwekhwalithi ephezulu okuvela kumabhrendi athembekile kuqinisekisa ukwethembeka nokuthula kwengqondo. Ukwengeza, ukudluliselwa kwesimanje kuvame ukuza nezici ezithuthukile njengezilungiselelo zohambo ezilungisekayo, ukuqapha okukude, namandla okuxilonga, okuthuthukisa ngokwengeziwe ukusebenza kwawo nokusebenza kwawo.
Isiphetho: Yamukela Amandla Okuvikela
Sengiphetha, ama-thermal relays kanye ne-thermal overload relays yizingxenye ezibalulekile endaweni ye-automation yezimboni kanye nobunjiniyela bukagesi. Ikhono labo lokuvikela izinjini nezinye izinto zikagesi ekushiseni ngokweqile kuqinisekisa ukuphila isikhathi eside, ukusebenza kahle, nokuphepha kwezinhlelo zezimboni. Ngokuqonda izimiso zabo zokusebenza nokukhetha ama-relay alungile ohlelo lwakho lokusebenza, ungavula amandla aphelele alawa madivayisi avikelayo anamandla. Yamukela amandla ama-thermal relay kanye nama-thermal overload relay, futhi uvikele imishini yakho nokusebenza ezingozini zokushisa ngokweqile.
