Ntxiv nrog rau kev ua kom zoo nkauj ntawm ib puag ncig, cov kab hluav taws xob high-voltage crisscrossed los ntawm phav phav volts yuav muaj kev phom sij rau cov neeg nyob ze vim qhov hluav taws xob hluav taws xob tsim nyob ib puag ncig lawv. Qhov no tsuas yog nyob ntawm lub zog ntawm electromagnetic teb.
Thaum tib neeg raug hluav taws xob siv hluav taws xob ntawm 50 ~ 200 kV / m, tej zaum yuav muaj mob taub hau, kiv taub hau, qaug zog, pw tsaug zog tsis zoo, tsis qab los noj mov, ntshav, plawv plawv thiab lub hauv nruab nrab lub paj hlwb txawv txav. Tau kawg, ntawm no yog hais txog qhov hluav taws xob ntau tshaj 100 kV ultra-high voltage kis tau tus mob, raws li cov cai feem ntau tsis yog los ntawm thaj chaw nyob, yog li cov neeg zoo tib yam tuaj yeem tiv thaiv los ntawm kev puas tsuaj. Hauv cov nroog thiab thaj chaw nyob, feem ntau ntawm cov kab hluav taws xob xaim hluav taws xob nrog qhov hluav taws xob qis dua 1 txhiab volts tau teeb tsa ntawm qhov siab, uas muaj kev cuam tshuam me ntsis rau tib neeg lub cev. Yog hais tias lub high-voltage kis tau tus mob ntawm 1 mus rau 100 kV yuav tsum tau dhau los ntawm cov chaw nyob, nws yuav tsum tau teem tsawg kawg yog 6.5 meters saum toj no av.
Tsis tas li ntawd, kev sib kis ntawm cov chaw taws teeb hauv feem ntau ntawm peb lub teb chaws yog 220 kV.
Lub 220 kV Yuanshan North Line yog qhov hluav taws xob tseem ceeb hauv thaj tsam sab hnub poob ntawm Chengdu. Nyob rau hauv cov huab cua kub tsis ntev los no tsis ntev los no, cov kab tau tshwm sim txawv txav thaum muaj xwm txheej kub ntxhov, tab sis vim tias cov kab no hnyav hnyav heev thiab tsis tuaj yeem cuam tshuam, Chengdu Power Supply tam sim ntawd txiav txim siab siv txoj kev ua haujlwm nyob hauv equipotential nrog qhov kev pheej hmoo loj tshaj plaws thiab qhov siab tshaj plaws. technical nyuaj nyob rau hauv lub neej ua hauj lwm project kom tshem tawm qhov poob.
Thaum 7:30 sawv ntxov, kev tshem tawm hluav taws xob equipotential pib. Nyob rau hauv lub hnub kub, 8 tus neeg ua haujlwm tau koom tes nrog kev sib raug zoo. Lawv muab lub thaiv, txuas nrog cov ntaiv insulated, muab tso rau ntawm cov khaub ncaws ua haujlwm tiv thaiv, nce ntaiv, ntes 220 kV high-voltage kab rau hauv cov khoom siv hluav taws xob, thiab polished cov hlau clamp… Plaub teev tom qab, qhov kub thiab txias ntawm cable clamp ntawm cov khoom siv nyob rau sab loj ntawm ntauwd 10 rov qab mus rau qhov qub, thiab kev tshem tawm haujlwm tau ua tiav sai sai yam tsis muaj kev cuam tshuam rau cov khoom siv hluav taws xob. Lub 220 kV Yuanshan North Kab txuas ntxiv thauj cov khoom thauj hauv "tag nrho lub xeev", ntxiv kev txhim kho lub caij ntuj sov kurtosis lav peev xwm ntawm Chengdu daim phiaj hluav taws xob.
