Isisekelo futhi angaphinde

Electricians abanolwazi izaba zokuthi uma isihlangu exhunywe kwi-izintambo isisekelo nezinyawo futhi Imigudu ebekelwa phansi othintana - awudingi sikhathazeke ngalutho. isisekelo Avikelayo futhi Vanishing kuyadingeka ukuze nokugcinwa ukufaka kagesi yokuthi umuntu abanjwe ugesi lapho i iphutha ukwahlukanisa.

Kufanele sinake inkinga uxhumano phansi wire ipayipi kwamanzi nokuthuthwa bafudumale. Lokhu akukwazi kwenziwa noma kunjalo! Lokhu kungase kuholele ekulahlekeni kwemali ukuphila, futhi uzobe bayiswe ngokuphepha ngaphansi kwesihloko esithi lokuhlukunyezwa zikagesi! sijeziso kuyinto ejele.

izingcweti eziningi abaqhuba eyenziwe wesifunda phansi. Bona ukuxhuma "zero" babashayeli zokuzivikela futhi abasebenza earthing-pin. Lokhu kuyingozi kakhulu! Ezimweni evutha-off ngokuvamile zenzeka iphaneli "phansi ukusebenza". Ngakho ku izindlu ikhompyutha kwakhiwa noma kuyabanda namanye amadivayisi 220 is. Njengoba esimweni sokuqala, izisulu akunakugwenywa, ne umehluko kuphela nokuba ukuthi akekho ukuba bathwale umthwalo, ngaphandle owenza lokhu kuhlobana. Ngokuvamile uhlushwa abanikazi ngokwabo, ukonga on ucingo ngogesi abaqeqeshiwe.

Isisekelo futhi angaphinde ngokuvamile asetshenziselwa njengoba omunye ongakhetha nokuvikeleka. Umzimba omkhulu iphaneli electrical ngamunye phansi has zero ezingaba, ezisabalele ngokusebenzisa ipuleti, has ukuxhumana kwezindlu ngumuntu yasibamba umshudo. Zero Guides zokuhlala, batholakala esitezi, futhi, ukuthi uxhumekile ku-icala isihlangu. ekupheleni ngamunye alethwe umshudo yayo, lapha wire le "phansi" noma "nokunyamalala", njengoba olikhethayo ukuyibiza.

Ugesi - lena ngebutho elikhulu, kodwa ngempela yingozi. Naphezu kweqiniso lokuthi sekuyisikhathi eside kuchaziwe, abalwa, ihlanganiswe amatafula ezihlukahlukene amavolumu umxhwele, zokulawula nohlaka olubhekele, ebheka sinusoidal yezinzwa at a imvamisa 50 Hz, ingamamitha neophytes ukwesabe futhi bethukile. Omunye wemibuzo njalo uba isisekelo futhi angaphinde. nemibono engqubuzanayo ngale ndaba akusho asinikeza impendulo ecacile. Indlela ukusetha iqiniso kule ndaba eyinkimbinkimbi kanye sína umkhuba? isisekelo zokuzivikela Vanishing kudinga ukucatshangelwa ngokucophelela futhi enesibopho.

Kagesi ohlelweni kagesi uhlukaniswe: izitshalo, okuyinto ziphakeme kunezindlela 1 kV ngempumelelo earthed inethiwekhi noma ekhishwe inyumbazane hlangothi. Ngoba icala lokuqala it unikezwa umsebenzi enemisinga okusezingeni eliphezulu, okwesibili - kanye ongaphakeme phansi iphutha. Kukhona futhi kuze kube 1kV inethiwekhi kagesi. Kubo, uma earthed futhi wahlukaniswa hlangothi. Emahhovisi kakhulu futhi amakhaya sebenzisa inketho earthed eRussia.

Umgomo we operation ye wesifunda ngaphansi kwegama isisekelo futhi angaphinde.

Ngemva contact nge voltage noma isigaba of housing metal oluhambisana zero, kwenzeka esikhathini esifushane inethiwekhi wesifunda. Kuleli qophelo, wamanje is likhule laba ngu nenani elikhulu. Lokhu kubangela amadivayisi ezithothene leso, obhekene ukulondeka nesivikelo. Bakhonza njengabashumayeli fuses, wesifunda oluseduze. Bona vala umugqa ngendlela esifike ngesikhathi, okuyinto feeds izinto ezisebenzisa obonakele. Kunoma ikuphi, kukhona isikhathi silinganiselwe for the Sae Ukukhipha ngokuzenzekelayo umugqa okuyiphutha.

Babashayeli angaphinde futhi isisekelo eyenziwa ekhethekile kuhlinzekelwe izimo ezinjalo. Wiring owodwa esigabeni kungase yesithathu umqhubi ikhebula noma ngocingo. Ukuze uvikele iyunithi inqanyuliwe ngesikhathi okuhleliwe, ukumelana we "Isigaba-zero" kumjikelezo kufanele kube encane. Ukuze angaphinde futhi phansi ukuze sibe abafundisi abaphumelelayo, ukufakwa amanethiwekhi kanye nokuxhumana isicelo nezidingo elawula kakhulu izinga. Futhi esheshayo amandla nokunqamula kumaphoyinti okufinyelela e emgqeni iphutha, nisekeliwe kokungathathi hlangothi, futhi angaphinde kulokhu kuqinisekisa voltage low. Uma uthinta umuntu emzimbeni lisebenze ayifakiwe ngokuphelele amathuba yokuthi umuntu abanjwe ugesi. Lapho, nisekeliwe hlangothi, isisekelo kokungathathi hlangothi uhlobo oluthize zomhlabathi.
