Isiphi isinyathelo voltage?

NabasePoland izintambo phezulu zikagesi ziye zaba ngemfanelo evamile landscape ezakha kakhulu ezweni lanamuhla ukuthi abaningi babo bamane awuboni. Naphezu indawo okusezingeni eliphezulu babashayeli ukuvimbela touch ngephutha, zingabantu, nokho, kubabangele ezazingase zibe ingozi. Wonke umuntu ukhumbula isimo kusukela eseyingane, lapho abazali bakhe wabona wire eziphukile eziwele phansi, bezama ukuthola kulendawo, "umgwaqo leshumi." Lokhu kuvimbela umuntu abanjwe ugesi, njengoba isinyathelo voltage incipha nge ibanga. Sonke siyazi ukuthi akunakwenzeka ukuya izintambo eziphukile. Nokho, ezinjalo isinyathelo voltage lowo azi yodwa kuze abantu Ihluzo Elingafaki Ukuqoka ezaziwayo. Le ndatshana izozama engaphezulu ukuqonda lo mbuzo, echaza, ngokwezwi nezwi, "phezu iminwe".

Ngakho isinyathelo voltage - kuyinto umehluko ezingaba phakathi emilenzeni, noma kuyiqiniso ukuthi, phakathi kwezindawo ezimbili (noma ngaphezulu) zehlukaniswe kusuka komunye nomunye emihlanganweni iphimbo ibanga. Esikhathini incazelo izinqubo eziningi Ihluzo Elingafaki Ukuqoka ngokuvamile zisebenzisa isilinganiso yamanzi. Empeleni, kwezinye izimo, Ukuqhathanisa kagesi kanye namanzi kwamukelekile ngempela, njengoba lula ukuqonda izinqubo. Sizoqhubeka.

Cabanga ukuthi yezinsika waphula ukudluliswa umugqa nokukodwa ongale kocingo bawela voltage phansi. Uma wire - icilongo, wamanje - amanzi, esikhundleni nabo emhlabathini kuyoba lwalelo chibi. Ubukhulu bayo iyona indawo esakaza lapho umuntu akwazi ukumanzisa izinyawo. A ichibi kwakhiwa ngoba amanzi akakwazi konke kweso cwilisa inhlabathi. Inani wokusakaza zone incike inani lamanzi edabula ipayipi per unit isikhathi.

Manje emuva ugesi. Umthombo voltage kudala umehluko ezingaba phakathi kwezindawo ezimbili komugqa, futhi, i- ephakeme voltage kanye RMS zamanje, aba maningi endaweni eyingozi emhlabeni izintambo elengayo. Ukubukeka "amaxhaphozi" elibangelwa ukuphakama ukumelana ohmic kwenhlabathi: wamanje phansi iluphu (ngokuvumelana Sae 4 Ohm) endaweni wokusakaza incane noma, lalingekho nhlobo.

Cabanga ukuthi eduze wire eziphukile uyindoda. Ngenxa ibanga phakathi kwezinyawo, kunamathuba umehluko. Futhi ngenxa ukumelana umzimba - futhi i kagesi. Eqinisweni, kusho ukuthola umuntu abanjwe ugesi. Futhi, uma emva shock ngogesi umuntu ewela (ngokugcwele noma isandla), kuphela kuchubekisela isimo ngoba ukwanda isinyathelo voltage. Ngaphezu kwalokho, uma isikhundla mpo umzimba, notshwala zamanje eduze nentaba "umlenze - ngezinyawo," ukuthi ngemva kokuwa nezinye ngamaketanga akhiwa, okungase idlule inhliziyo, ukuzenza i ngengozi esondelayo ekuphileni. Kulula ukuqonda ukuthi izilwane (izinkomo, amabhere, amahhashi), ivaleleke wamanje esakaza zone, basengozini enkulu kunabantu, ngoba ibanga eliphakathi phambili indluzelekazi imilenze eside, ngakho-ke, isinyathelo voltage kuyingozi kakhulu.

Kusukela konke lokhu singaqondile, singafinyelela eziphethweni eziningana:

• uma lingena wamanje Ukusabalala kwendawo wire ephukile (noma ezinye ukwehluleka) kunoma yisiphi isimo akufanele ukwethuka ukusebenzisa. Lapho egijima ibanga amathe siba sikhulu kunesijeziso ngesinyathelo, ngokulandelana, amandla iyakhula. Ikakhulukazi, ngoba umuntu uzama ungasuki umthombo wamanje, isinyathelo voltage kuba yingozi nakakhulu;
• balolonge esakaza zone kungaba zehluke uhla umehluko inhlabathi conductivity.

Ukushiya ungaphandle kwebanga isinyathelo voltage kungaba materials non-conductive (isib ikholoni ibhodi ezomile); igxuma ngonyawo olulodwa (kulesi simo, ayikho ezingaba umehluko); noma kancane ukuphuma, eligoqiwe izinyawo ndawonye.
