Ngaphezu kokulimaza ubuhle bendawo, imigqa yamandla kagesi aphezulu enqamula izinkulungwane zama-volts izoba nemiphumela elimazayo kubantu abaseduze ngenxa yenkambu kazibuthe kagesi ekhiqizwa eduze kwabo. Lokhu kuncike kakhulu emandleni omkhakha we-electromagnetic.
Uma abantu bechayeka kumandla kagesi angu-50 ~ 200 kV/m, kungase kube khona ikhanda, isiyezi, ukukhathala, ukungalali kahle, ukungakuthandi ukudla, igazi, isimiso senhliziyo nemithambo yegazi kanye nokungajwayelekile kwesistimu yezinzwa. Vele, lapha kubhekiselwa ku-voltage wezintambo zikagesi ezingaphezu kuka-100 kV ze-ultra-high, ngokwemithetho ngokuvamile hhayi ngezindawo zokuhlala, ukuze abantu abajwayelekile bavikeleke ekulimaleni. Emadolobheni nasezindaweni zokuhlala, imigqa eminingi yokusabalalisa amandla ene-voltage engaphansi kwe-volts eyi-1 000 isethwe ekuphakameni okucacisiwe, okunomthelela omncane emzimbeni womuntu. Uma intambo kagesi enamandla amakhulu ephakathi kuka-1 no-100 kV kufanele idlule ezindaweni zokuhlala, kufanele isethwe okungenani ngamamitha angu-6.5 ukusuka phansi.
Ngaphezu kwalokho, ukuhanjiswa okukude ezindaweni eziningi zezwe lethu ikakhulukazi ku-220 kV.
I-Yuanshan North Line engu-220 kV iyindawo ebalulekile yokuphakela ugesi endaweni esentshonalanga ye-Chengdu. Esimweni sezulu esiqhubekayo sokushisa okuphezulu kwakamuva, ulayini ubonakale unesici esiphuthumayo sokushisa esingavamile, kodwa ngenxa yokuthi ulayini wawumthwalo osindayo futhi wawungenakuphazanyiswa, i-Chengdu Power Supply yanquma ngokushesha ukusebenzisa indlela yokusebenza bukhoma ene-equipotential enengozi enkulu yokuphepha futhi ephakeme kakhulu. ubunzima bezobuchwepheshe kuphrojekthi yokusebenza bukhoma ukuze kuqedwe ukulahlekelwa.
Ngo-7:30 ekuseni, kwaqala ukuqedwa kwe-equipotential kagesi. Ngaphansi kwelanga elishisayo, opharetha abangu-8 babambisana eduze nangokuhlelekile. Babeka ibhlokhi, baxhuma ileli elivalekile, bagqoka izingubo zokusebenza ezivikelwe, bagibela isitebhisi, babamba ulayini we-voltage engu-220 kV bawufaka endaweni elinganayo, base bepholisha intambo yocingo... Ngemva kwamahora amane, izinga lokushisa le-cable clamp okokusebenza ohlangothini olukhulu lombhoshongo we-10 kubuyele kokujwayelekile, futhi umsebenzi wokuqeda waqedwa ngokushesha ngaphandle kokuphazamisa ukunikezwa kwamandla. I-Yuanshan North Line engu-220 kV iyaqhubeka nokuthutha umthwalo “esimeni esigcwele”, ithuthukisa ngokwengeziwe ikhono lesiqinisekiso se-kurtosis sasehlobo segridi yamandla kagesi yase-Chengdu.
