Isingeniso: Sikhuluma ngezimoto zamandla amasha, singahlala sizwa ochwepheshe bekhuluma “ngohlelo lukagesi oluthathu”, ngakho-ke “uhlelo lukagesi oluthathu” lusho ukuthini? Ezimotweni zamandla amasha, uhlelo lukagesi oluthathu lusho ibhethri lamandla, i-drive motor kanye nesistimu yokulawula kagesi. Kungashiwo ukuthi uhlelo lukagesi oluthathu luyingxenye eyinhloko yemoto entsha yamandla.
imoto
Injini ingumthombo wamandla wemoto entsha yamandla. Ngokwesakhiwo nomgomo, injini ingahlukaniswa ngezinhlobo ezintathu: idrayivu ye-DC, ukuvumelanisa kazibuthe unomphela, kanye nokungeniswa kwe-AC. Izinhlobo ezahlukene zezinjini zinezici ezihlukile.
1. I-DC drive motor, i-stator yayo inguzibuthe unomphela, futhi i-rotor ixhunywe kumanje oqondile. Ulwazi lwefiziksi yesikole samabanga aphezulu lusitshela ukuthi umqhubi onikwe amandla uzobhekana namandla e-ampere endaweni kazibuthe, ngaleyo ndlela kubangele ukuthi i-rotor ijikeleze. Izinzuzo zalolu hlobo lwemoto yizindleko eziphansi kanye nezidingo eziphansi zesistimu yokulawula ye-elekthronikhi, kanti okubi ukuthi inkulu futhi inamandla okusebenza abuthakathaka. Ngokuvamile, izithuthuthu zikagesi ezisezingeni eliphansi zizosebenzisa ama-DC motors.
2. I-synchronous motor ehlala njalo kazibuthe iyinjini ye-DC, ngakho umgomo wayo wokusebenza uyafana nowe-DC motor. Umehluko ukuthi i-DC motor idliswa nge-square wave current, kanti i-synchronous motor synchronous kazibuthe inikezwa i-sine wave current. Izinzuzo zama-motor synchronous kazibuthe unomphela ukusebenza kwamandla aphezulu, ukwethembeka okuhle kakhulu, nosayizi omncane uma kuqhathaniswa. Okubi ukuthi izindleko ziphakeme kakhulu, futhi kunezidingo ezithile zohlelo lokulawula ngogesi.
3. Izinjini zokungenisa ziyinkimbinkimbi kakhulu ngokwesimiso, kodwa zingahlukaniswa cishe zibe izinyathelo ezintathu: okokuqala, ama-windings ezigaba ezintathu zenjini axhunywe kukushintshana kwamanje ukuze kukhiqizwe inkambu kazibuthe ejikelezayo, bese i-rotor eyakhiwe ngamakhoyili avaliwe. inqanyulwa endaweni yamagnetic ejikelezayo Imigqa yamagnetic field yenza i-current induced, futhi ekugcineni amandla e-Lorentz akhiqizwa ngenxa yokuhamba kweshaja kagesi endaweni kazibuthe, okuyinto kubangela ukuthi i-rotor ijikeleze. Ngenxa yokuthi insimu kazibuthe ku-stator ijikeleza kuqala bese i-rotor ijikeleza, i-induction motor ibizwa nangokuthi i-asynchronous motor.
Inzuzo ye-induction motor ukuthi izindleko zokukhiqiza ziphansi, nokusebenza kwamandla nakho kuhle. Ngikholwa ukuthi wonke umuntu uyakubona ukonakala. Ngenxa yokuthi idinga ukusebenzisa i-alternating current, inezidingo eziphezulu kusistimu yokulawula kagesi.
Ibhethri Lamandla
Ibhethri lamandla liwumthombo wamandla okushayela injini. Njengamanje, ibhethri lamandla lihlukaniswa kakhulu ngezinto ezinhle nezimbi. Kukhona i-lithium cobalt oxide, i-ternary lithium, i-lithium manganate ne-lithium iron phosphate. I-Yuan lithium kanye namabhethri e-lithium iron phosphate.
Phakathi kwazo, izinzuzo zamabhethri e-lithium iron phosphate yizindleko eziphansi, ukuzinza okuhle nempilo ende, kanti ububi buwukuqina kwamandla aphansi kanye nempilo yebhethri engathi sína ebusika. Ibhethri ye-lithium ye-ternary iphambene, inzuzo yi-low density yamandla, kanti ububi buwukungaqini kahle nempilo.
Uhlelo lokulawula ngogesi
Isistimu yokulawula ye-elekthronikhi iyitemu evamile. Uma ihlukaniswe iziqephu, ingahlukaniswa ngesistimu yokulawula imoto, isistimu yokulawula imoto, kanye nesistimu yokuphatha ibhethri. Isici esiyinhloko sezimoto ezintsha zamandla ukuthi amasistimu okulawula ama-electronic ahlobene eduze. Ezinye izimoto zize zibe nesethi yezinhlelo zokulawula zikagesi ukuze zilawule zonke izinto ezisebenza ngogesi emotweni, ngakho-ke kulungile ukuzibiza ngokuhlanganyela.
Njengoba uhlelo lukagesi olunezintambo ezintathu luyingxenye eyinhloko yezimoto ezintsha zamandla, uma uhlelo lukagesi oluthathu lonakele, akungabazeki ukuthi izindleko zokukhanda noma ukushintshwa ziphezulu kakhulu, ngakho-ke ezinye izinkampani zezimoto zizoqalisa impilo kagesi emithathu. inqubomgomo yewaranti. Yiqiniso, uhlelo lwe-electric amathathu akulula ukuphuka, ngakho izinkampani zezimoto zinesibindi sokusho iwaranti yokuphila konke.
