Yintoni eyona kuyingozi ngoku ebantwini? amaxabiso ezibulalayo yingozi yangoku

electric - lo mntu ugesi, emva koko ukuze ube kukothuka - yokusabela kakhulu kwizinto ngamandla, nto leyo umsinga wombane. Kuyaqondakala ukuba nayiphi na into enobungozi yangoku ubomi babantu. Eli nqaku kwakhona waphendula umbuzo wokuba yintoni ngoku kunye ombane ziyingozi ebantwini.

Iqala electric

Kuxhomekeka imeko ukuqalela ukothuka inokuba ezahlukahlukeneyo. Ukuba umntu ufumene abanjwe eyomeleleyo yombane, oku kungabangela iingxaki kunye nokuhamba kwegazi nokuphefumla. Kwiimeko kakhulu kungaqala fibrillation wentliziyo - imisipha intliziyo iqala ukuba ukudideka elingafani. Ekubeni intliziyo okunene eyeka yokusebenza, ukuhamba kwegazi oyekayo. Ukuba akasinikanga uncedo lokuqala ngendlela ngexesha umntu uyafa.

ungakubhabhisa nombane kuvela amaxesha amaninzi xa embetha abantu ngamandla bakhe ngoku ukuya ku-1000 V. Burns kunokwenzeka phantsi kwempembelelo a njengangoku 1 A nangaphezulu. Oku kwenzeka kakhulu xa usebenza ngoku ukuya ku-1000 angenako ukuthobela imithetho engundoqo yokhuseleko. Busbar isabelo ibekwe kufutshane kakhulu ukuya kummandla emzimbeni, phakathi obhobhozayo yintlantsi kwenzeka, nto leyo ekhokelela ukutsha kakhulu.

Ukuba umntu ngengozi ndafumana yintlantsi, yangoku ngexesha uxhulumaniso kunye umzimba kumo esikule ukuya ° 60. Oku kukhokelela iproteni amahlwili, aqhumisele kuveliswa kummandla ochaphazelekayo. Ukutsha zidalwa ugesi, unyango kunzima.

Iimpawu yokwenzakala ngenxa yokothuka yombane

Kukho into enje njengoko ileyibhile umbane. Le isikhumba ezifileyo umbala tyheli, nto leyo imbonakalo efana zengqolowa. Ukuba lwangoku singene nzulu eluswini, ancedisana umzimba abune kunye nexesha.

Iimpawu ukutsha zombane:

• isikhumba kwindawo yempembelelo ihlazo;
• kwisayithi ye eziko yaqala ukubonakala ovutha kuya-;
• umcu kwindawo yempembelelo zalaba;
• isikhumba akwazi ukufumana amaqhekeza ezimbiwa kwi ukwanda impahla.

Kuyingozi kakhulu bonke, ukuba ukhatywa ngumbane wangena kule ndawo:

• ezintlafunweni;
• back;
• izandla;
• shins;
• Nape kwentamo;
• entanyeni.

Ukuhlelwa ombane malunga nefuthe phezu kwabantu

Le yangoku yombane kuyahlukahlukana okukwiqondo yayo ukusuleleka kwabantu. Kungaba:

• obuphathekayo;
• neotpuskayuschego;
• fibrillyatsionnogo.

Uvalo ebizwa ngoku yombane kwi impembelelo apho umntu avakalelwa into eku- ecacileyo. Mamela langoku ukubulawa ngokudutyulwa kwi 0.6 Ma.

Neotpuskayuschego - umbane ebangela ezixhuzuxhuzulayo ngokuzenzekelayo le imilenze ukuba abachukumisa ngcingo uyihlubile.

Alternating odlula ezikhoyo iiseli zomzimba womntu, oko ingenisa la mandla apho loo mntu ukusebenza ngokunamathela.

Fibrillyatsionnogo yangoku ngexesha impembelelo kubangela iingxaki kunye nenkqubo intliziyo. Ngelo xesha, umntu uyafa ngenxa zokuma.

current esiyingozi

Kuxobekeka kwezo meko, ngawo umzimba womntu uyakwazi ukudlula lombane ubungakanani ezahlukeneyo kwaye, ngenxa yoko, inokuba ngenxa yokulimala ohlukahlukeneyo. Kufuneka wazi ukuba ngoku, yingozi abantu, kukho amandla ngoku abangaphezu kwe-15 Ma, apho umntu akanako ukuzisindisa ngaphandle koncedo. Amandla sangoku 50 ma unako ukubangela umonakalo enzima kwimpilo, kwaye 100 ma imizuzwana 1-2 phantsi isenzo kuqwalaselwa obethe yingozi kwaye zikholisa ukuba zokuma.

Kuyingozi kakhulu ngoku yabantu AC, nezihlandlo nguwuphi na omkhulu kwe 50-500 Hz. Ukuba ixabiso layo malunga 9 ma, umntu unako ukuzikhulula ovela kumthombo amanxeba (ucingo). Kufuneka kuqondwe ukuba ubomi kunye nempilo yabantu ingozi kwaye ngoku rhoqo, nto leyo ayibulale kuphela xa ngaba ngaphezulu 20-25 Ma.

Yeyiphi AC ayingozi ebantwini?

Abantu abasebenza rhoqo kwizixhobo ze-elektroniki kunye zombane, uyazi ukuba yintoni i-AC ne DC. Kodwa asingabo bonke kubo ulwazi, yeyiphi into eyingozi ngakumbi ebantwini.

Kuyaqondakala ukuba umbane kuyingozi ebantwini, oko iphenjelelwa yimiba ezininzi. Ezifana:

• elide sagcina contact ngayo;
• indlela oyihambayo langoku baluwela umzimba;
• Yintoni amandla waba hit;
• lokumelana emzimbeni womntu.

Liyiqwalasele Kuyingozi AC yabantu. izizathu:

• DC ekhoyo imele efanayo ifuthe ebisebenza xa umzimba zabantu, ukuba liselikho 3 izihlandlo ezingaphezu kwama-AC. Oku kwenzeka ngenxa yokuba alternating current imnandi kakhulu ngakumbi imizwa kudaleke izihlunu kunye nentliziyo.
• Ukufa ngenxa umvumbo current idla kwenzeka ngenxa zokuma. Umngcipheko ukufa ekhoyo amaninzi xa usebenzisa alternating current.
• Resistance ofakwe umzimba womntu, le ngasentla DC, kwaye phezulu amaza, inowuthi uxhathiso.

Ngoko kucacile ukuba ifildi yangoku kuyingozi kakhulu ebomini bomntu nje rhoqo.

Yintoni DC kuyingozi ukuba abantu

Umngcipheko kubantu zombini AC kunye DC yangoku. Into eyingozi ngakumbi AC izihlandlo ezingama-35 ngaphezu abasisigxina. Kubangel 'umdla ukwazi ukuba ukhuseleko luthathwa DC langoku 50 Ma, kwi ifildi enye yangoku olu phawu 10 kuphela Ma. Kodwa eyona nto ibalulekileyo - ingozi nawuphi kuxhomekeke ngqo kwi ngegalelo lako.

It ingqalelo:

• kwi yombane ukuya ku 400 V alternating kuyingozi ngoku;
• ukuba ombane yi 500 V, ukungasithakali yangoku ngokulinganayo;
• kwi ombane ayi-500 V DC kuyingozi kakhulu.

Ezitshintshisanayo hits yangoku bondlekile nqapha efanayo rhoqo ngokuqhubekayo. Xa usindwa alternating current, afumane ithuba bahlukane kude nomthombo sisilonda. Kuyaqondakala ukuba ingozi kuphela imboniselo yangoku, wabetha umntu, kodwa kwakwenziwa iyelenqe ubethwe. Indlela kakhulu eyingozi ezikhoyo intliziyo, ingqondo kunye nemiphunga.

yangoku Direct kuyingozi ngabantu, kususela ukhatywa ngumbane okanye ukutsha bangaba abonakale abanengxaki yokuphefumla.

Ngawaphi amalungu achaphazelekayo umbane?

Indlela ngamandla usindwa umzimba womntu ngexesha bothukile, kuxhomekeke apho indlela yangoku Kwadlula. Ukuziqhelisa, kukho iindlela ezininzi apho langoku kudlula umzimba:

• Xa umntu ethatha wire Sibhenca, ephantsi kwempixano, ngezandla zozibini. Le ndlela isandla - ngesandla, wegqitha phakathi izandla, ezichaphazela inkqubo yokuphefumla nentliziyo.
• Xa umntu emi phezu komhlaba, kwangaxeshanye uchukumisa wire ebalelelwe lilanga ngesandla. Le ndlela kuthiwa ngesandla - ngonyawo, le singena ezikhoyo amalungu lwangaphakathi nokuphefumla kunye nentliziyo.
• Sebenza iinyawo ezixabisa phezu komhlaba, kummandla nozinzo olungachananga. obhobhozayo yangoku ifunyenwe up. Ngumendo wangoku ibizwa ngokuba umlenze - emlenzeni.
• Xa umntu yachukumisa ngempazamo umqhubi sakhe isabelo intloko. Indlela ongathi uthunyelwe kuyo intloko - ngesandla, intloko - imilenze.
• Iindlela ezininzi eziyingozi apho langoku kucanda umzimba, ngabo eziquka ibaluleke kakhulu kwinkqubo yabantu.

abanjwe Indlela yingozi zombane

Ukuba umbane ukubetha amandla ombane ayi-500 V, umntu uya zintlungu kwindawo touch namalungu, isikhumba ngomlilo. Kwaye kukho kubonakala kakhulu ukuba ukuphefumla zokumisa okanye yomntanakhe oyekayo.

Kufuneka kuqondwe ukuba amandla ombane ayi-500 umahluko V phakathi iintlobo ezimbini imisinga cishe engekho. Phakathi yangoku ujikeleze lonke umzimba womntu kunye ombane uxhomekeke nonlinear. Ngoko ke, xa ombane Bakwanda ukunyuka amandla yangoku.

Kuyo nayiphi na imeko, amandla ugesi kuxhomekeke kwiimeko ngamnye yomfundi apho umntu yeyela igridi amandla.
