Indlela ukucacisa zero futhi isigaba? Umbala izintambo - isigaba zero

Kukhona, eqinisweni, hhayi eningi zonke izinhlobo izinhlobo babashayeli nebudlelwano bawo. Esikhathini kwamandla kanye ukuhlukanisa babashayeli zokuzivikela. Abanye abantu baye bezwa amazwi anjengokuthi "zero" futhi "Isigaba" wire. Kodwa lapha futhi kukhona imibuzo. Indlela ukucacisa zero futhi isigaba e inethiwekhi real?

Yiziphi babashayeli e isokhethi?

Kungenzeka ukubhekana umbuzo "yini esigabeni futhi singathathi hlangothi", ngaphandle kokuya ehlathini lokuthola isakhiwo, izinzuzo kanye amaphuzu ongathandeki ezintathu okhombisa noma emihlanu-isigaba izifunda. Zonke ungenza ukuthi empeleni phezu iminwe, okwembula abavamile kakhulu endlini uphuma khona, okuyinto lihlelwe ifulethi noma indlu yangasese iminyaka eyishumi - iminyaka eyishumi nanhlanu edlule. Njengoba ubona, lokhu isokhethi ixhunywe izintambo ezimbili. Indlela ukucacisa zero futhi isigaba?

kanjani izintambo e kugesi odongeni futhi ziyini na?

Njengoba ubona, kunomehluko ezithile phakathi abasebenzi kanye zero. Uyini isigaba ukuqokwa zero? Bluish noma nombala oluhlaza - umbala esigabeni wire, zero kuboniswa yimuphi omunye imibala, ngaphandle Yiqiniso, oluhlaza okwesibhakabhaka. Kungaba ophuzi, oluhlaza okotshani, omnyama ezimthende. zamanje ingahambi yomqhubi weSifundo hlangothi. Uma sithatha futhi ningathinti ideskithophu ke ayikho into ezokwenzeka - ke akukho mahluko ezingaba (eqinisweni, inethiwekhi aluphelele, futhi zinamandla encane angasahlelwa kulinganiswa kodwa, kakhulu, e millivolts). Kodwa nge umqhubi isigaba ngeke galo yephuka. Ukuthinta kungase kufake hlangana shock ngogesi ngisho ukubulala. Lokhu wire njalo nginomdlandla, a wamanje ageleza nalokho kusuka ugesi kanye Transformers ezincane kagesi futhi izitshalo amandla. Kufanele ukhumbule njalo ukuthi izinga touch-umqhubi noma kunjalo ayikwazi, ngoba ngisho voltage amakhulu volts kungaba yingozi. Futhi lapho uphuma khona voltage isigaba amabili namashumi amabili.

Ngikuphi okuhlukileko kuneGreyidini eSoviet earthing-pin?

Indlela ukucacisa zero futhi isigaba kulesi simo? Ngezinye lapho uphuma khona, iklanyelwe ukuhlangabezana nezindinganiso ze-European, kukhona ezintathu nje umqhubi. Eyokuqala - isigaba, okuyinto wanikeza futhi zipendwe ngemibala ehlukahlukene (ngaphandle shades blue). Esesibili - zero, okuyinto iphephile ngokuphelele thinta futhi ezinemibala eluhlaza okwesibhakabhaka. Kodwa eyesithathu conductive zokuzivikela ngokuthi zero. Ivame ezinemibala umbala ophuzi noma oluhlaza. Rapolozhen washiya nezinyawo, sekuqalile ukuba - ngezansi. Isigaba wire kuya esandleni sekudla kanye nasetulu, ngokulandelana. Sikhishwe lezi zici umbala kulula ukucacisa lapho esigabeni, futhi lapho zero, futhi lapho esivikelo umqhubi hlangothi. Kodwa kuyini na?

Kungani sidinga umqhubi okuvikela ukuze earthing-pin?

Uma esigabeni yakhelwe ukuphakela amandla lapho uphuma khona, zero - sokukhipha emthonjeni, kungani yaseYurophu elawula omunye ngocingo? Uma imishini ixhunyiwe, isebenze kahle, futhi bonke wiring isesimweni esihle sokusebenza, i-zero zokuzivikela ngeke iqhaza kuwukudlala. Kodwa uma kwenzeka ngokuphazima kweso into lapho a isekhethi noma phezu yamandla aphindeke kabili noma short circuit kunoma iyiphi ingxenye idivayisi, lamanje uthola izindawo ngokuvamile ngaphandle ithonya lakhe, ukuthi ayixhunyiwe iyiphi isigaba noma nge zero. Umuntu nje akwazi ukuzwa shock ngogesi lona ngokwalo. Esikhathini isimo okubi kakhulu ungafa ngisho kuwo, ngoba imisipha yenhliziyo ungayeka. Kulapha futhi kudingeka umqhubi zokuzivikela hlangothi. Yena "ithatha" isekhethi wamanje kanye ithumela kwaze kwaba phansi emhlabathini noma umthombo. Imininingwane enjalo zincike isakhiwo Izintambo zikagesi ezisobala kanye nezici flat. Ngakho-ke, ungakwazi ukuthinta ngokuphepha imishini - akuyikubakho abanjwe ugesi. Into wukuthi wamanje ithatha indlela amelane njalo. Emzimbeni womuntu ukubaluleka kwalesi ipharamitha ezingaphezu kweyodwa kiloomah. Ngo esivikelo umqhubi ukumelana ingeqi a kwetshumi ambalwa eyodwa Ohm.

Kuchazwa uya khona iziqondiso

Indlela ukucacisa zero futhi isigaba? Noma kunjalo sibhekene imiqondo le. Ikakhulukazi uma kudingekile ukulungisa lapho uphuma khona noma wiring ukukwenza. Ngakho-ke kubalulekile ukuba baqonde kahle lapho umqhubi. Kodwa kanjani ukucacisa zero futhi isigaba? Kumele kukhunjulwe ukuthi zonke manipulations zaloluhlobo ugesi yingozi. Ngakho-ke, uma yokungaqiniseki kwakwenzayo uthintane onguchwepheshe kangcono. Uma kakade angena esitolo esidayisa futhi izintambo kulo, khona-ke udinga ukuqala ngokuphelele de-lingakunika amandla efulethini. Okungenani, kungasindisa impilo nokuphila. Njengoba kushiwo ngaphambili, ngokuvamile esigabeni ukuqokwa zero eniyenzayo ngosizo umbala. Nge kophawu efanele ukuze uwahlukanise ngeke kube nobunzima. Black (noma brown) - Color izintambo isigaba, zero uqobo tint bluish noma bluish. Uma-European standard isokhethi isethi, eyesithathu (zero zokuzivikela) oluhlaza noma ophuzi. Kuthiwani uma wiring kuyinto ezinombala ofanayo? Ngokuvamile, esimweni esinjalo, bentambo semikhawulweni ngokuvamile ezikhethekile ekuvikeleni tube kokuba wayefisa anemibala. Zibizwa ngokuthi "amashubhu nangokuvikela".

Ukunqunywa babashayeli nge ukufakwa kokumqoka kuphela ekhethekile

Indlela ukucacisa zero futhi isigaba? Ukuze wenze lokhu, kungcono ukuthenga ekhethekile inkomba screwdriver. Isibambo lokhu ithuluzi eyenziwe ngepulasitiki ayevumela noma obala. Ngaphakathi diode okuhlangene - ingilazi yesibani. Ingxenye engenhla endaweni enjalo ukufakwa kokumqoka kuphela metal. Indlela ukucacisa zero futhi isigaba le ndlela?

Inqubo umsebenzi ukusebenza, njengoba kulinganiswe le ukufakwa kokumqoka kuphela inkomba:

• de-nginomdlandla efulethini;
• thina uhlanza kancane bentambo kuphelile;
• Thina zala wawahlukanisa, ukuze ngephutha kubangele short circuit ngokuthintana phakathi isigaba futhi zero;
• Ukuvula inkinobho nezinto yamanje efulethini;
• ukuthatha isibambo ukufakwa kokumqoka kuphela ukuthi has a enamathela Kwe-dielectric Heating;
• ukubeka umunwe (noma Inkomba okusezingeni eliphezulu), oxhumana naye ukuthi itholakala kwi ezingemuva kwezisekelo;
• Thina uthinte ukusebenza ekupheleni inkomba komunye umqhubi angenalutho;
• uqaphele ukwenza ngokuvumelana nawo ukusabela a ukufakwa kokumqoka kuphela;

• ngu inyumbazane siyaqonda ukuthi umqhubi ezisele - zero.

Ukufakwa kokumqoka kuphela inkomba iyaphendula yokubakhona voltage. Yiqiniso, ukuthi alikho wire hlangothi. Nokho, kukhona ethile abalulekile le ndlela. Ngosizo ebonisa ukufakwa kokumqoka kuphela abakwazi ukuqonda ukuthi ukunquma: isigaba zero, umhlaba - lapho kunjalo nge esidayisa European.

Indlela I-ukuzimisela esigabeni futhi zero nge voltmeter

Uma izintambo kungukuthi ababethi umbala ezifanele, futhi isandla akuyona ukufakwa kokumqoka kuphela inkomba, ungaya enye indlela. Sidinga voltmeter (multimeter, umhloli). Kuyadingeka ukuba wasibeka phezu ububanzi oyifunayo - phezu volts ezingamakhulu amabili AC. Njengoba umhloli ukucacisa isigaba? Thatha enye umqhubi ezisabalele kusukela unit (V ezikhonjiswe). Namathisela-ke siyinikeze umqhubi ngaphambilini uyeke nginomdlandla (ikhona). Khona-ke, lamanje enikeziwe (ithuba inkinobho). Futhi nje silungise lokho kubonisa isibonisi yomculo. Phela okungenhla futhi uvala amandla kagesi, futhi siya isiqeshana umhloli kakade ngakolunye umqhubi. Uma lutho kungaveli, kusho ukuthi kukhona noma zero noma zokuzivikela isisekelo umqhubi kokungathathi hlangothi phambi kwethu. Nokho, ungasebenzisa enye indlela okuphendula umbuzo: "Indlela yokubona futhi zero isigaba, kanye emhlabathini." Ukuze wenze lokhu, futhi uyeke nginomdlandla efulethini, ulungise V ngocingo kwenye izintambo. Eyesibili nokujikijela futhi kunoma iyiphi babashayeli ezintathu. voltage aguquliwe. Uma inaliti alinyakazi ke ukuthi ukhethe hlangothi futhi zokuzivikela. Ngakho, kufanele voltage switched off futhi ushintshe isikhundla imbaza ezikhumulweni V (uyiphonse kwenye umqhubi ngaphambilini ubuningi). Nalapha futhi, zihlanganisa zamanje futhi senze izilinganiso ezifanele. Sabe ukumhlinza efanayo, kodwa izinguquko futhi umqhubi. Manje udinga ukuqinisekisa imiphumela. Uma inombolo yokuqala kwaba enkulu, kusho ukuthi siye kulinganiswa voltage phakathi umqhubi isigaba (okuyinto hung Clem V) kanye no-zero. Ngakho, wire yesibili kuyoba earthing zokuzivikela. Le ndlela isekelwe ezingaba umehluko nesilinganiso.

izindlela Exotic ekunqumeni esigabeni futhi zero e wiring

Kukhona futhi "izindlela ezivamile", okuyinto akusho ukuba khona noma yimuphi amathuluzi akhethekile. Zingasetshenziswa ngaphandle futhi ezimweni ezimbi nakakhulu, njengoba zihlotshaniswa kwandisa amathuba okuphathwa impilo nokuphila. Ngokwesibonelo, amazambane indlela. Ngenxa yale njongo, babashayeli pre-de-nginomdlandla gqoka obusanda kusikwa ucezu amazambane. Kuyadingeka ukuvimbela izintambo uthinte nomunye, ukuthi akukho isekhethi phakathi kwazo. Khona-ke, nje ambalwa, zinamandla sisetshenziswa, futhi sibheke amazambane. Uma omunye ingxenye wire eduze blue ebusweni, bese kulethwa esigabeni.
