Pamusoro pekukuvadza kunaka kwezvakatipoteredza, mitsetse yakakwira-voltage yakayambuka nezviuru zvevolts ichave nemhedzisiro inokuvadza kune vanhu vari pedyo nekuda kwemunda wemagetsi unogadzirwa wakavatenderedza. Izvi zvinonyanya kuenderana nekusimba kwenzvimbo yemagetsi.
Apo vanhu vanotarisana nemagetsi emagetsi emagetsi e50 ~ 200 kV / m, panogona kuva nemusoro, dzungu, kuneta, kurara kusina kunaka, kurasikirwa kwechido, ropa, hurongwa hwemwoyo uye hutachiona hwepakati penheyo. Ehe, pano kunoreva voltage yeanopfuura 100 kV ultra-high voltage transmission mitsara, zvinoenderana nemirairo kazhinji kwete kuburikidza nenzvimbo dzekugara, saka vanhuwo zvavo vanogona kuchengetedzwa kubva mukukuvara. Mumaguta nenzvimbo dzekugara, mazhinji emagetsi ekugovera mitsara ane voltage pazasi 1 000 volts akaiswa pahurefu hwakatarwa, husina humbowo hunoita pamuviri wemunhu. Kana mutsetse wekutakura wemagetsi uri pakati pe1 ne100 kV uchifanira kupfuura munzvimbo dzinogara vanhu, unofanira kugadzikwa zvishoma ne6.5 metres kubva pasi.
Mukuwedzera, kutapurirana kure munzvimbo zhinji dzenyika yedu kunonyanya 220 kV.
Iyo 220 kV Yuanshan North Line inzvimbo yakakosha yekugovera magetsi munzvimbo yekumadokero kweChengdu. Munguva ichangopfuura tembiricha yemamiriro ekunze, mutsara wakaonekwa usiri wenguva dzose wekupisa kwechimbichimbi chirema, asi nekuti mutsara waive wakanyanya kuremerwa uye waisagona kuvhiringwa, Chengdu Power Supply yakabva yafunga kushandisa equipotential mhenyu yekushanda nzira ine njodzi huru yekuchengetedza uye yakanyanya kuchengetedzwa. kuoma kwehunyanzvi muhupenyu hwekushanda chirongwa kubvisa kurasikirwa.
Na7:30 am, kubviswa kwemagetsi equipotential kwakatanga. Pasi pezuva rinopisa, vashandi ve8 vakashanda pamwe chete uye vakarongeka. Vakaisa chivharo, vakabatanidza manera anopoteredzwa, vakapfeka mbatya dzekushanda dzakavharidzirwa, vakakwira manera, vakabata tambo ye220 kV high-voltage mu equipotential, uye vakakwenenzvera tambo yewaya… Maawa mana gare gare, tembiricha yetambo inosungirira midziyo iri parutivi rukuru rweshongwe 10 yakadzokera kune yakajairika, uye basa rekubvisa rakakurumidza kupera pasina kukanganisa magetsi. Iyo 220 kV Yuanshan North Line inoramba ichitakura mutoro mu "yakazara nyika", ichienderera mberi nekuvandudza nguva yezhizha kurtosis vimbiso kugona kweChengdu magetsi grid.
