Corona yog tshwm sim los ntawm lub zog hluav taws xob tsis sib xws uas tsim los ntawm cov neeg coj tsis sib xws. Nyob ib puag ncig lub zog hluav taws xob tsis sib xws thiab nyob ze ntawm lub electrode nrog lub vojvoog me me ntawm curvature, thaum lub zog hluav taws xob nce mus rau qee qib, kev tso tawm yuav tshwm sim vim yog huab cua dawb, tsim lub corona.
Los ntawm cov xwm txheej rau kev tsim corona, peb tuaj yeem pom tias cov teb hluav taws xob tsis sib xws, cov neeg xa hluav taws xob tsis sib xws, thiab cov hluav taws xob siab txaus yog cov xwm txheej tsim nyog rau kev tsim corona. Yog li ntawd, corona yuav raug tsim tawm ntawm qhov kawg ntawm cov hluav taws xob siablub cev muaj zogcov xov hlau, tshwj xeeb tshaj yog rau cov hluav taws xob ntsuas. Rau cov cav tov siab dua 6kV, lub corona ntawm stator winding yuav pom tseeb dua, thiab qhov hluav taws xob siab dua, qhov teeb meem corona yuav loj dua. Yog li ntawd, rau cov xov hlau hluav taws xob siab, cov kev ntsuas kho tiv thaiv corona raug coj los ntawm kev siv cov xov hlau electromagnetic tshwj xeeb thiab ntxiv cov kab xev resistive rau sab nraud ntawm cov kauj winding.
Lub cev muaj zog zaus hloov pauv tau siv lub tshuab hloov zaus. Lub zog hluav taws xob los ntawm lub tshuab hloov zaus txawv ntawm nthwv dej sine ntawm lub zog fais fab kev lag luam, tab sis nthwv dej plaub fab nrog kev nce thiab nqis siab. Lub nthwv dej tshwj xeeb no ua rau lub zog hluav taws xob nkag ntawm lub cev muaj zog tsis tu ncua thiab siab. Lub zog hluav taws xob ntau dhau uas yog ob npaug ntawm lub zog ntsuas, vim yog qhov ceev ceev ntawm lub zog hluav taws xob ntau dhau no, yuav ua rau muaj kev faib hluav taws xob tsis sib xws hauv cov xov hlau ntawm lub cev muaj zog. Txawm hais tias feem ntau cov cav hloov zaus yog cov cav hluav taws xob qis, txoj kev muab hluav taws xob tshwj xeeb yog kom muaj cov teb hluav taws xob tsis sib xws hauv lawv cov xov hlau.
Los ntawm kev tshuaj xyuas cov yam ntxwv ntawm tus lej ntawm kev tig thiab ntev ntawm lub cev muaj zog, thawj zaug thiab zaum kawg ntawm qhov qis-voltage siab-power lub cev muaj zog winding dais yuav luag tag nrho cov voltage amplitude, thiab kuj yog qhov feem ntau yooj yim rau teeb meem hauv lub cev muaj zog winding. Ntxiv mus, los ntawm kev tshuaj xyuas ntawm cov txheej txheem embedding ntawm lub winding, Kev puas tsuaj rau thawj tig kauj yog qhov loj dua, thiab yog li ntawd qhov kev pheej hmoo yog ntau dua. Qhov no yog vim li cas ntau lub cev muaj zog tsim khoom muab kev tiv thaiv tshwj xeeb rau thawj thiab zaum kawg coils. Rau cov qis-voltage siab-power variable-frequency motors, vim tsis sib npaug teb lub zog thiab pulse spike voltage, qhov kawg ntawm lub cev muaj zog winding muaj cov xwm txheej yooj yim rau corona tiam. Txhawm rau tiv thaiv qhov tshwm sim ntawm corona hauv lub cev muaj zog variable zaus, tshwj xeeb anti-corona electromagnetic xov hlau yuav tsum tau siv rau hauv cov windings ntawm lub cev muaj zog variable zaus, thiab tshwj xeeb kev tiv thaiv yuav tsum tau ua rau thawj thiab zaum kawg coils.
