Yuav high-voltage kab yuav ua rau hluav taws xob hluav taws xob muaj teeb meem
1. Tsis muaj hluav taws xob hluav taws xob, tsuas yog electromagnetic induction
Zoo li substations, qhov cuam tshuam tiag tiag ntawm high-voltage kis tau tus mob ntawm thaj chaw ib puag ncig yog vim qhov cuam tshuam ntawm electromagnetic induction, es tsis yog hluav taws xob hluav taws xob.
Qhov no yog vim hais tias, txawm hais tias qhov hluav taws xob nyob rau hauv high-voltage kis tau tus mob yog siab heev, zaus ntawm kis tau tus mob hluav taws xob lub zog yog tseem 50 hertz, yog li tsuas yog electromagnetic induction phenomenon yuav tshwm sim, tsis electromagnetic tawg.
2. Tsis txhob kho "corona" raws li hluav taws xob hluav taws xob!
Lub txim hluav taws xob tsim los ntawm cov kab sib kis tau hu ua corona. Corona tso tawm yog ib qho tshwm sim tawm uas tshwm sim vim muaj hluav taws xob siab siv nyob rau saum npoo ntawm cov kab sib txuas, ua rau huab cua ionization. Lub zog dissociation ntawm huab cua molecules feem ntau yog 20-30 kV/cm. Thaum lub zog hluav taws xob ntawm qhov hluav taws xob hluav taws xob ntawm cov kab hluav taws xob ntau tshaj qhov nqi no, lub suab nrov nrov tuaj yeem hnov los ntawm kab, qhov tsis hnov tsw ntawm ozone tuaj yeem hnov qab, thiab thaum hmo ntuj, xiav ntshav fluorescence tuaj yeem pom nyob ib ncig ntawm cov hlau, uas yog corona. tso tawm.
Corona ntawm cov kab hluav taws xob tuaj yeem ua rau corona poob, lub zog zaus electromagnetic teb (AC kis tau tus mob), DC hluav taws xob teb los (DC kis), xov tooj cua cuam tshuam (siab zaus mem tes tam sim no), thiab suab nrov, tab sis nws tsis tsim hluav taws xob ntau zaus. thiab tsis ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv.
3. Yam koj yuav tsum xav txog rau high-voltage transmissions yog kev nyab xeeb
Cov pa tawm hluav taws xob nyob rau hauv cov txheej txheem atmospheric yog kwv yees li 30kV / cm, uas txhais tau hais tias qhov kev tso tawm theoretical ntawm 330kV yog 11cm. Xav txog cov xwm txheej tiag tiag (xws li huab cua, thaj chaw thaj chaw, thiab lwm yam), qhov kev tso tawm qhov deb yuav tsawg dua li qhov nqi no. Los ntawm qhov no, nws tuaj yeem pom tias qhov kev ncua deb ntawm 330kV kis tau tus mob me me, thiab nws qhov kev nyab xeeb nyob deb tuaj yeem xav tias tsis loj heev. Tam sim no, qhov kev ncua deb ntawm cov rwb thaiv tsev sab laug thaum teeb tsa txoj kab deb tshaj qhov kev nyab xeeb ntawm cov qauv saum toj no.
