Isikhundla enethiwekhi emudwebeni wesifunda. Isikhundla kwezisekelo ku circuit: Standard

Ngu kakhulu imvelo yabo embonini lobuchwepheshe kukhona iqoqo izinhlelo nemiklamo. A unjiniyela abanekhono akufanele kuphela ngokuqiniseka ukufunda lezi zinhlelo, kodwa futhi ukuba ukwazi ukwenza kubo. Kusukela iziqondiso ku-art sebuningini enkulu, isakhiwo ngasinye has izici zayo siqu, kwanqunywa ukuba kube sezingeni elifanele izimiso imidwebo kanye imidwebo.

Ukuze lula kwakha luhlaka bese kufundwa imidwebo ejwayelekile kazwelonke ihlanganiswe zonke izakhi kanye namadivayisi egumbini dokhumenti, phakathi 21.614 futhi 21.608 GOST. Kukhona futhi echazwe isicelo imithetho ihluzo evamile on the Umdwebo, kuhlanganise isiqu enethiwekhi akhona ku circuit.

Izimbangela OAG

OAG isifinyezo notation kunemibandela ingcaca. Ngenxa yokuthi umdwebo kuyinto Incwadi engokomthetho, futhi kumelwe zilungiswe kahle. Uma yenziwe kahle, uzokwenza ukuba kahle ukuhumusha okuqukethwe umdwebo. Uma imithetho enjalo ingekho, ziye zenzeka izinkinga eziningi inkani enkulu ekwakhekeni izingxenye noma eyakhelwe izakhiwo.

Ngesikhathi lapho imidwebo wakudonsela uhlangothi, onjiniyela obuzama lula inqubo umdvwebo. Lokhu sekwenze kwaba lula ukukhiqiza design kanye nezincwadi inhlolovo isikhathi esifushane. Ngo ukwakhiwa yesimanje sekuyisikhathi eside besebenzisa amaphakheji ekhethekile isofthiwe ngokwenza imidwebo. Bona kakhulu lula ukuphila abaklami, kodwa OAG uyaqhubeka bahlale bemazi. Ngo kagesi imidwebo ubunjiniyela ngoba bonke 95% aqukethe izithombe ingcaca okunemibandela eyodwa kuphela.

Esikhathini Umdwebo, eziningi izakhi, ikakhulukazi ukwakhiwa imidwebo. Ubukhulu indaba emfushane izakhiwo ethathwe enye wokuhamba ukuze anamakhulu mahlanu. Lokhu kusho ukuthi isikhala phansi zingancishiswa izikhathi eziyikhulu, anamakhulu mahlanu.

Kokunye isikali wokuhamba eyodwa isentimitha ku ephepheni okulingana imitha elilodwa ngokoqobo. Ngezinye izikhathi, nabaqambi kudingeka uvumelane uyibhala elincane iphepha, setha izakhi. Ukuze uxazulule le nkinga, sebenzisa OAG. Lokhu kukuvumela ukuba unike izakhi multi-level kagesi ku ngesakhiwo flat.

Isikhundla kwezisekelo ku circuit

Lapho wakha indlu noma isakhiwo zezimboni ngeke akwenze ngaphandle ukufakwa amadivayisi kagesi noma zikagesi. Ukuze uzwisise ukuthi uzibeke kuphi umshini othile, omakhi uyazinaka ekubizweni isokhethi kulombhalo wesifunda.

Design isigaba "Izinsiza kusebenza kagesi" kudinga ukulungiselelwa kwazo zonke imidwebo kunesidingo. Inkosi isethi imidwebo ukwakhiwa phansi ethize noma igumbi kuhlanganisa izinhlobo eziningana imibhalo. Eyokuqala idayagramu olulodwa imoto i-switchgear - ikubonisa bonke abasebenzisi, uvezwa izimpawu ezivamile, okulandelayo is a plan egumbini ukubekwa. Okulandelayo iyona esifakiwe.

Ngo ubunjiniyela ingxenye enkulu izakhi okunemibandela ingcaca ezakha Izitolo zikagesi. Isokhethi ivumela ukuletha amandla kagesi kusuka esiteshini amandla noma esincane sikagesi ukuze umthengi sokugcina.

Wonke umuntu uyazi ukuthi esidayisa isendaweni udonga. Kuleli zwe lanamuhla cishe wonke amadivaysi egijima ku ugesi kusukela 220 volts. Ngenxa yalokho, inani kuyaqabukela esingaphansi kwezinsuku ezimbili ezindlini noma emahhovisi.

Izinhlobo ubheke enethiwekhi phezu izinhlelo

Njengoba imishini kagesi, nezinyawo iziphiwo zomusa ezahlukeneyo ekugcwalisekeni nenjongo. Ngakho-ke, igama elithi kwezisekelo yesifunda liyadingeka ukwenza ngezindlela ezihlukahlukene. Cabangela izinhlobo ezinkulu enethiwekhi:

• Bipolar - esiku-220 engama-volt angu enethiwekhi, okuyinto efakwe kule ezindlini;
• ezintathu isigxobo - okufanayo ezimbili-pole nezinyawo, kodwa ezengeziwe earthing umqhubi esehlisa, bayizithunywa ejwayelekile yesimanje European;
• ezine-pole - standard ubudala esebenziswe lapho ezingeni voltage ka 380 volts; rosettes enjalo ikakhulu atholakala umkhakha (uma kunesidingo yokuxhuma motor ezintathu okhombisa wekhono encane);
• ezinhlanu isigxobo esetshenziselwa ukuxhumana olukhethekile imishini industrial.

Izinhlobo enethiwekhi lokukhuphula inqubo

Ngaphandle ukubulawa zilwane, nezinyawo zihlukaniswa indlela ukufaka:

• nge ukufakwa ezifihlakele (bafakwe udonga);
• kulungiselelwa evulekile (babe izindlu zabo, okuyinto unamathele ebusweni asekelayo);
• kokufaka yangaphandle (izindlu zokuzivikela abe uthuli okusezingeni eliphezulu namanzi, senzelwe ukufakwa ngaphandle).

Kuhlelo YaseYurophu akubiza zikagesi, kuncike degree of isivikelo uthuli futhi umswakama ukusebenzisa izincwadi ezimbili-Latin-IP kanye nenombolo zamadijithi amabili okungasenani. Inombolo yokuqala ebonisa isivikelo Ukungena lezinto zangaphandle, owesibili - kusuka umswakama. Kukhona value kusuka 0 kuya 9, ayanda inombolo, ngcono ukuvikelwa.

Isikhundla Isikimu GOST enethiwekhi

Imithethonqubo ezibekwe ngokucacile uphawu esidayisa kulombhalo. Rosette ngokuvamile uvezwa njengomyeni umbuthano isigamu nge selilonke kuyoshaya phezulu kusuka ngezansi. I dash kubonisa uhlobo izisekelo. Omunye ukuthi okuguquguqukayo isokhethi, imigqa emibili parallel - ngokulandelana, onokuphazamiseka kwengqondo okuguquguqukayo, kabili.

izici ezintathu, elise fan, kwakusho ukuthi tripolar yokuxhuma. Uma kukhona ukuxhumana zokuzivikela umqhubi uxhumano idwetshwa umugqa flat parallel maphakathi umkhumbi, ke ngaso sonke Izitolo ukufakwa evulekile.

Ukukhonjwa nezinyawo, sekuqalile izifunda nge ukufakwa ezifihlakele simiswe ngalendlela lelandzelako: maphakathi isingasiyingilizi ungenisa omunye umugqa. It is iqondiswe kusukela maphakathi bubheke dash, okhombisa inani esidayisa izingongolo. Ngokuvamile, lokhu isokhethi umane bricked odongeni. It has a degree eliphansi abe isivikelo, kodwa ngenxa yokuthi ngaso sonke obala izingxenye conductive kufihlwe odongeni, kuphephile.

Uhlangana ukwakhelwa njengohlelo nezinyawo, sekuqalile izikimu okuqinile semi mbuthano abamnyama. Lokhu kusho ukuthi sibhekene isokhethi nge high value-IP. Lokhu kukuvumela ukuba uyifake ngaphandle, ezifana emgwaqeni.

Lapho ungathola omelela izinhlobo ezahlukene Izitolo?

Lawula ekubizweni enethiwekhi ku isikimu Standard. Icacisa ubukhulu ngqo nohlobo okunemibandela notation sokuqhafaza.
