Kev nyab xeeb deb ntawm high-voltage kab.Qhov kev ncua deb yog dab tsi?
Txhawm rau tiv thaiv tib neeg lub cev los ntawm kev kov lossis mus ze rau lub cev hluav taws xob, thiab tiv thaiv lub tsheb lossis lwm yam khoom los ntawm kev sib tsoo lossis mus txog
lub cev hluav taws xob ua rau muaj kev phom sij, nws yog ib qho tsim nyog yuav tsum khaws ib qho kev ncua deb ntawm lub cev hluav taws xob, uas yuav dhau los ua kev nyab xeeb.
Muaj pes tsawg metres qhov chaw nyab xeeb?
Nco ntsoov: qhov siab dua qhov voltage, qhov kev nyab xeeb ntau dua.
Ua tib zoo saib cov lus hauv qab no.Tuam Tshoj Cov Hluav Taws Xob Hluav Taws Xob Kev Nyab Xeeb Kev Nyab Xeeb Kev Ua Haujlwm muab kev nyab xeeb ntawm cov neeg ua haujlwm thiab lub zog hluav taws xob AC kab.
| Yam tsawg kawg kev nyab xeeb nyob deb ntawm cov kab hluav taws xob overhead thiab lwm lub cev raug them | |
| Voltage theem (KV) | nyab xeeb nyob deb(m) |
| ＜1 | 1.5 |
| 1 ~ 10 | 3.0 |
| 35-63 : kuv | 4.0 |
| 110 | 5.0 |
| 220 | 6.0 |
| 330 | 7.0 ib |
| 500 | 8.5 |
Nws puas muaj kev nyab xeeb kiag li yam tsis tau kov cov kab hluav taws xob siab?
Cov tib neeg niaj hnub yuav yuam kev ntseeg tias ntev npaum li lawv txhais tes thiab lub cev tsis kov cov kab hluav taws xob siab, lawv yuav muaj kev nyab xeeb kiag li.Qhov no yog qhov yuam kev loj!
Qhov xwm txheej tiag tiag yog raws li hauv qab no: txawm tias tib neeg tsis kov cov kab hluav taws xob siab, yuav muaj kev phom sij nyob rau hauv ib qho kev ncua deb.Thaum qhov sib txawv voltage
loj txaus, huab cua yuav puas los ntawm hluav taws xob poob siab.Tau kawg, qhov loj dua ntawm huab cua nyob deb, qhov tsawg dua nws yuav raug tawg.Txaus cua nyob deb tau
ua tiav rwb thaiv tsev.
Puas yog high-voltage hlau "sizzling" tawm?
Thaum lub high-voltage xaim xaim hluav taws xob, hluav taws xob muaj zog yuav tsim nyob ib ncig ntawm cov hlau, uas yuav ionize huab cua thiab tsim corona paug.
Yog li thaum koj hnov cov suab "sizzling" ze ntawm cov kab hluav taws xob siab, tsis txhob poob siab tias nws tawm.
Ntxiv mus, qhov siab dua qhov voltage, qhov muaj zog corona thiab lub suab nrov dua.Thaum tsaus ntuj lossis hauv huab cua los nag thiab pos huab, faint xiav thiab ntshav halos tuaj yeem
Kuj tseem pom nyob ze ntawm 220 kV thiab 500 kV high-voltage kis kab.
Tab sis qee zaum thaum kuv taug kev hauv nroog, kuv tsis xav tias muaj "sizzling" suab nrov hauv cov xaim hluav taws xob?
Qhov no yog vim hais tias 10kV thiab 35kV tis kab nyob rau hauv lub nroog cheeb tsam feem ntau yog siv insulated nyob ntawm tej, uas yuav tsis tsim huab cua ionization, thiab qhov voltage theem yog tsawg,
corona siv zog tsis muaj zog, thiab lub suab "sizzling" tau yooj yim npog los ntawm ib puag ncig lub suab nrov thiab suab nrov.
Muaj lub zog hluav taws xob nyob ib puag ncig cov kab hluav taws xob sib kis tau zoo thiab cov khoom siv hluav taws xob hluav taws xob loj.Cov conductors nyob rau hauv no hluav taws xob teb yuav muaj
induced voltage vim electrostatic induction, yog li cov neeg siab tawv ntau muaj lub tswv yim ntawm kev them xov tooj ntawm tes.Nws yog qhov txaus ntshai kom muaj kab lis kev cai.Qhov no yog ib tug series ntawm
tuag.Tsis txhob sim.Lub neej tseem ceeb dua!Feem ntau, yog tias koj nyob ze rau cov kab hluav taws xob ntau dhau.
