1) Tus neeg teb xov tooj yuav tsum hnav cov hnab looj tes insulating rau kev kuaj xyuas hluav taws xob siab.
2) Thaum kuaj xyuas hluav taws xob, lub tshuab hluav taws xob uas tau dhau qhov kev sim, yog nyob rau hauv lub sijhawm siv tau, thiab ua raws li qhov ntsuas hluav taws xob ntawm qhov system yuav tsum tau siv. Tshwj xeeb, nws yog txwv tsis pub sib xyaw nrog electroscopes uas tsis tau raws li qhov system voltage. Vim hais tias, yog tias lub electroscope nrog high voltage theem yog siv nyob rau hauv lub low-voltage system, nws yuav tsis raug ntes txawm tias muaj hluav taws xob; txwv tsis pub, kev nyab xeeb ntawm tus neeg teb xov tooj tsis tuaj yeem lav.
3) Rau kev tshuaj xyuas hluav taws xob sab nraum zoov hauv hnub los nag, nws yog txwv tsis pub siv cov khoom siv hluav taws xob zoo tib yam (tsis muaj dej tsis muaj dej) lossis cov pas nrig insulating kom tsis txhob ya raws qhov hluav taws xob los yog dej ntws tawm, uas tuaj yeem ua rau tus kheej raug xwm txheej.
4) Tshawb xyuas lub tshuab electroscope ntawm cov khoom siv hluav taws xob ua ntej, thiab nws yuav tsum tau lees paub tias nws yog qhov zoo.
5) Ntawm ob sab ntawm cov khoom siv hluav taws xob hluav taws xob (xws li ob sab ntawm cov hluav taws xob hluav taws xob, qhov siab thiab qis voltage sab ntawm lub transformer, thiab lwm yam) thiab cov khoom uas yuav tsum tau luv luv Circuit Court thiab grounded, ua lub zog tshuaj xyuas hauv theem.
(2) Cov txheej txheem ntawm kev tshuaj xyuas hluav taws xob.
1) Ntsuas electroscope yam tsis muaj kev sib cuag ncaj qha nrog cov neeg ua haujlwm nyob. Feem ntau cov electroscope ntshiab luminous voltage tsis ntau tshaj 25 feem pua ntawm cov ntsuas voltage. Yog li ntawd, ntev npaum li qhov tsis zoo electroscope nyob ze rau lub cev them (6, 10, 35kV systems, txog 150, 250, 500mm, raws li), nws yuav emit lub teeb (los yog muaj suab thiab lub teeb tswb).
2) Siv insulating rub rods los tiv thaiv hooking los yog bearing ntawm cov conductors. Cov khoom siv sab nraum zoov muaj cov qauv siab, thiab cov pas nrig rwb thaiv tsev yog siv rau kev tshuaj xyuas hluav taws xob. Nws tsuas tuaj yeem txiav txim siab seb cov cuab yeej siv tau nyob li cas raws li qhov tsis muaj qhov ci ntsa iab thiab tawm suab, uas tsis yog qhov yooj yim thiab nyuaj. Thaum nruab hnub, sparks tsis tuaj yeem pom meej, feem ntau yog mloog lub suab tawm. Lub suab nrov tom qab ntawm lub substation yog nrov heev, thiab kev xav yog me ntsis unfocused, thiab nws yog ib qho yooj yim mus txiav txim tsis ncaj ncees lawm. Yog li ntawd, txoj kev ua haujlwm yog qhov tseem ceeb. Yog hais tias tus pas nrig insulating yog hooked los yog nias tawm tsam tus neeg xyuas pib thaum lub sij hawm kuaj hluav taws xob, yuav tsis muaj cov pa taws thiab tawm suab txawm tias muaj hluav taws xob. Vim tias qhov kev sib txuas tiag tiag tsis muaj qhov sib txawv, qhov tseeb yog tias cov pas nrig insulating thiab tus neeg xyuas pib yuav tsum tau khaws cia rau hauv kev sib txuas virtual lossis rubbed rov qab thiab tawm ntawm qhov chaw ntawm tus neeg xyuas pib. Yog tias cov cuab yeej siv hluav taws xob, cov hluav taws xob thiab cov suab tawm yuav raug tsim los ntawm qhov sib txawv ntawm qhov paug tawm.
(3) Kev lees paub thiab paub qhov txawv yog tias muaj qhov hluav taws xob yog qhov tseem ceeb rau kev kuaj xyuas hluav taws xob. Koj tuaj yeem xa mus rau cov hauv qab no rau kev txiav txim.
1) Muaj hluav taws xob. Vim lub zog hluav taws xob muaj zog ntawm kev ua haujlwm voltage: ① Lub electroscope yuav tawm lub teeb (los yog lub suab thiab lub tswb nrov) thaum nws nyob ze ntawm tus neeg xyuas pib rau qee qhov kev ncua deb, qhia tias cov cuab yeej muaj kev ua haujlwm voltage; Tom qab ntawd, qhov ze ntawm lub electroscope yog rau lub cev them, qhov ci ntsa iab (los yog suab) yuav muaj zog dua. . Nws yog ib qho tseem ceeb heev rau tus neeg teb xov tooj yuav tsum ua tib zoo saib thiab tuav lub ntsiab lus no los txiav txim seb cov khoom puas raug them. ②Siv cov pas nrig insulating los xyuas cov hluav taws xob, thiab muaj lub suab "squeak" tawm. 2) static hluav taws xob. Lub peev xwm rau hauv av tsis siab, lub zog hluav taws xob tsis muaj zog, thiab lub tshuab hluav taws xob tsis pom kev thaum lub sijhawm kuaj hluav taws xob. Tom qab kev sib cuag nrog tus neeg xyuas pib, qee zaum nws tawm lub teeb; Tab sis raws li tus nqi hluav taws xob ntawm tus neeg xyuas pib dhau los ntawm electroscope → tib neeg lub cev → lub ntiaj teb tawm, lub electroscope brightness hloov ntawm lub zog mus rau qhov tsis muaj zog, thiab thaum kawg tawm mus. Qhov tshwm sim no yuav raug ntsib thaum cov hluav taws xob raug kuaj xyuas ntawm high-voltage ntev cable tom qab fais fab tuag.
3) Induction hluav taws xob. Zoo ib yam li hluav taws xob zoo li qub, lub peev xwm tsis tshua muaj, thiab cov electroscope tsis teeb thaum lub sij hawm kuaj hluav taws xob feem ntau.
4) Hauv qhov hluav taws xob qis qis, yog tias lub ntsuas ntsuas yog qhov ci, koj tuaj yeem siv lub ntsuas hluav taws xob kom paub qhov txawv ntawm qhov voltage nws yog dab tsi. Muab qhov hluav taws xob ntau ntawm multimeter rau ntau qhov sib txawv, thiab qhov ntsuas hluav taws xob rau hauv av yog tib tus nqi, uas tej zaum yuav yog qhov ua haujlwm voltage; qhov loj dua qhov ntau (qhov siab dua qhov kev tiv thaiv sab hauv), qhov siab dua qhov ntsuas hluav taws xob, uas tej zaum yuav yog hluav taws xob zoo li qub lossis induced voltage.
