Ukuvalwa kwamanje, okuzenzakalelayo, ukuvikelwa kokuvalwa kanye nezinye izindlela ezidinga ukubhekwa lapho ukhetha.
Ukuvikelwa kogesi kanye nemililo kuncike ekusebenzeni kwamadivayisi anqamula ngesikhathi sokuthola okukhona manje. Ukukhetha kanjani la madivayisi ukukhetha, sitshele esihlokweni.
I-1 UDO yamaqembu ahlukene amanethiwekhi kagesi
Wonke ama-automatic switch asetshenziselwa ukukhubaza umugqa ngesikhathi sokulayisha ngokweqile noma umjikelezo omfushane. Ezokuphepha okulula kakhulu okuhlukile, kusetshenziswa omunye umjikelezo wesifunda, obhekele ukusebenzelana nenethiwekhi yonke yasekhaya. Kepha le ndlela ilungele ngaphandle kwendlu encane kakhulu yengadi. Kwikheshi lapho kunezinhlobonhlobo zemishini yebhizinisi, kunconywa ukuhlukanisa abathengi emaqenjini amaningana. Lokhu kungaba, ngokwesibonelo, amaqembu amathathu: ukukhanyisa, izisekelo kanye namadivayisi wamandla; Eqenjini elihlukile, kwesinye isikhathi kunenethiwekhi yasemgwaqweni (kufaka phakathi igalaji nomhlangano).

Iqembu ngalinye linikwa amandla yi-subnet yalo, elihlinzekwa ngokushintsha kwalo okuzenzakalelayo kubhekwa njengamanje esisekelweni. Ungawathola kanjani amandla akhona kumaketanga? Ukuthola amandla wamanje adliwa umthamo womthwalo uhlukaniswe ngamandla kagesi wenethiwekhi kagesi (220 V). Uma, ngokwesibonelo, amandla aphelele awo wonke amadivaysi ayi-1 kW, khona-ke okukhona kunethiwekhi okunjalo kuzoba cishe ngo-5 A. Isigaba sesekethe sesilinganiso kufanele silingane nesinyathelo senani elitholwayo. Ngo umkhuba, isibonelo, ngenxa ukukhanyisa uhlelo, izintambo futhi imishini, kubalwa i-wamanje samanje 10, asetshenziselwa enethiwekhi - 16, imishini amandla - 25, ngokulandelana, Automata kumele ibalwa imisinga 10, 16 no-25 A.
3 Ukuvalwa okuzenzakalelayo
Yisiphi isici sesikhathi samanje? Le pharamitha ifaka isivinini sedivaysi kuze kube manje, inani layo elidlula inani eliphakeme. Empilweni yansuku zonke, ukushintshwa okuzenzakalelayo kwezinhlobo ze-B, C no-D, isikhathi esihlukile sesici samanje. Abaphuluki be-Type B Breaker basabela kumanje edlula inani eliphakeme kakhulu lezikhathi ezi-3-5, uhlobo C luyizikhathi ezi-5 ukuya kwezi-10, nohlobo lwe-D luyizikhathi eziyi-10-16. Izinhlobo B no-C zivame ukusetshenziswa kakhulu, noma kunjalo, kumanethiwekhi anamandla okusebenza kukagesi, kungcono ukuthenga i-D. Breaker Breaker.
U-Alexander Besspev, umphathi womkhiqizo we-Eaton
Ungahlukanisa umpheki wesifunda osezingeni eliphakeme ngezici eziningi. Naka ikhwalithi yezezindlu kanye nesisindo somkhiqizo - Iphaneli yangaphambili kufanele ibe monolithic, kufanelekile izingxenye zinobukhulu, futhi ucingo ngokwalo alulula kakhulu (kuqhathaniswa nezifaniselo). Isisindo esincane singasho ukuthi umenzi ogcinwe ezintweni zokwakha nemininingwane. Esikhathini esezingeni eliphakeme le-AV Clamps le-Cable nezinye izingxenye ezithwala njengamanje zenziwa ngethusi, elivumela insiza ukuthi ifudumale kancane (futhi i-OverHeat). Amadivayisi anjalo anezinketho eziningi, ngokwesibonelo, ahlome ngezintambo zokuvikela zeziqeshana zekhebula futhi abe nesikhombi sombala sesikhundla sokuxhumana.
4 Ukuvikelwa Amakamu
Ngokungeziwe kwabaphuluki besekeli, umnikazi wekotishi uzodinga ukushintshwa kwamanje kwamanje (eyaziwa nangokuthi amadivaysi okuvikeleka avikelekile, alawulwa yi-Differed Shutdown, i-UZO), umsebenzi wawo ukuvikela ngokuvalwa komhlaba. I-UDO ivikela abantu ekushaqekekeni kukagesi lapho ithotshisiwe ku-wire engenalutho noma icala le-hardware yensimbi, elibangelwa ngaphansi kwamandla kagesi asebenza ngenxa yokungasebenzi kahle. Imisipha yokujikeleza emhlabeni inqwaba impela inqwaba ingaholela emililweni, okungukuthi, i-RCD nayo ivimbela umlilo.
Ukushintsha kwekhwalithi engezansi: 1 - Ukucisha i-Grille (amapuleti ayi-9); 2 - I-Clamp yensimbi; 3 - Awekho amakhethini avikelayo; 4 - ikhamera yokuphekela ngaphandle
Ukushintsha kwekhwalithi: 1 - Amakhethini avikelayo; 2 - I-COMPR; 3 - Ukucisha i-Grille (amapuleti ayi-13); 4 - Igumbi lokucisha izici; 5 - Ukuhlaselwa kwesiliva
I-RCO kumele kufanele ifakwe amanethiwekhi lapho amathuba okushaqeka kukagesi emkhulu ngenxa yomonakalo wokufakwa kokufakwa kukagesi noma i-wiring. Lezi yizindlu zokugeza nawo wonke amakamelo amamanzi, kanye nenethiwekhi yasemgwaqweni. Khetha i-UZO ngokuya nge-watwage yamanje (elinganiswe kuma-milliampers - ma), incane inani, liphezulu ukuzwela kwensiza. Empilweni yansuku zonke, ama-UDOs ajwayele ukusebenzisa i-vuza lamanje le-10, 30 no-100 ma. Okubucayi kakhulu (okungu-10 noma ama-30 ma) kufakwa emaketangeni lapho ukuvikeleka okuphezulu kudingeka khona, ngokwesibonelo ezindlini zokugezela. Ama-Uzos abucayi kangako (ama-100 ma) afakwa emaketangeni, lapho kukhona khona okunamandla (2-3 kw nokuningi) motors kagesi namadivayisi afanayo: lapho sebevuliwe, ama-Uzos abucayi azophenduka amanga. Esihlangu, i-UZO General ifakwe ngemuva kwe-electrospheker kusethi ye-othomathikhi yokulungiswa kwesifunda sokujikeleza kwezindawo zesifunda ngasinye ezizovikela i-rcm ekulimaleni ngesikhathi somjikelezo esifushane. I-UZO kumele ifakwe kuphela ngokuhambisana nokushintshwa okuzenzakalelayo. Ngenye indlela, ungasebenzisa ama-breaker wesifunda wokwehluka kwamanje (avdt, noma ahlukahlukene), okuhlanganisa imisebenzi ye-RCD ne-Conftional Automata.
Emishini ethembekile, kusetshenziswa izinto ezibiza kakhulu - ngokwesibonelo, ukuhlaselwa kwesiliva koxhumana naye.

Ukuxilapha
Lesi yisifunda esikhulu kunazo zonke esifushane esikwazi ukukhubaza i-AV. Ungathola i-Automata ngekhono lokunqamula kwama-3,000, 4,500, 6000 no-10,000 A. Inani eliphakeme, liphezulu ukuthembeka, ukuqina kanye nezindleko zedivayisi. Isici sikhonjiswa ezindlini zedivayisi (izinombolo ngohlaka olungunxande).
