Kev kho Corona feem ntau muaj cov tshuab hluav taws xob, qhov siab {{{voltage transformer, thiab ib lub tshuab kho. Lub tshuab hluav taws xob muab lub zog, thaum lub siab siab- voltage transformer hloov pauv tshiab (AC) rau hauv qhov hluav taws xob siab rau kev kho. Cov tub ntxhais ntawm lub tshuab kho yog capacitor. Cov khoom siv yuav tsum tau kho yog tso ntawm ob electrodes. Raws li qhov voltage maj mam nce, ib tug corona ua kev lom zem tshwm sim, ua rau muaj oxidation thiab tawg tshuaj lom neeg. Tus txheej txheem no ua rau pawg hydroxyl, pab pawg carbon monants, roughening zaj duabso thiab pab kom txo qis thaj av.
Thaum kev kho Cornona, zaj duab xis feem ntau yog muab tso rau ntawm ob yob thiab kho nrog cov khoom siv biplar, nrog cov hluav taws xob tswj hwm ntawm kev ncua deb ntawm ntau centimeters. Qhov ua tau zoo ntawm Corona kev kho tau cuam tshuam los ntawm lub sijhawm kho, kub thiab av noo. Raws li lub sijhawm kho kom tsawg, nce siab kub thiab hloov cov av noo yuav cuam tshuam cov yeeb yaj kiab lub zog saum npoo thiab lub zog. Txhawm rau kom ntseeg tau cov duab zoo nkauj, tus txheej txheem kho Corona yuav tsum zam dhau txoj kev tsim ntawm cov lumps thiab nce ntxiv hauv lub zog saum npoo.
Corona kev kho yog dav siv rau ntau yam yeeb yaj kiab hom, tshwj xeeb yog polypropylene thiab tsawg} {zog {} Zog} Zog} Zog hluav taws xob plastics. Thaum cov huab cua sib txawv yog teem rau 5 hli thiab lub voltage raug kho kom haum rau 560 cmz, corona paug yuav tswj tau zoo tswj kom ntseeg tau tias kev kho mob zoo tshaj plaws.
