Kanjani Ukuchaza I-Performance YeLow Voltage Panel?

Ukuziqonda Kwizinhloso Zokuchazwa Kwe-Low Voltage Panel

Incazelo Ngezinhloso Zokuchazwa Kwe-Performance Yelow Voltage Panel

Ukuhlola ipleni yesivoltage emncane kubhekisa kakhulu ekusebenzisweni kwazo ngokujonga izinto ezithile njengekuthi ukulinganisa kuyaphila, uma imigodi ivalelwe kahle, kanye nokuthi izixhobo zokuphepha zisebenza kanjani kumathuba angasebenza ngamavolti angu-1,000 AC noma amavolti angu-1,500 DC. Lezi ziphando zidlala phakathi kweminyaka eyahlukene kungekudala kumva kusuka kofaktori (ezibizwa ngokuthi FATs), ngqo kabefore kokuthi kusetyenziswe, kanye nomnyaka wonke ukuze kuthintelwe ukuthi konke kufanisane nokudizayiniwe. Isifundo esisha sikaNETA esavela ngo-2022 sabonisa ukuthi ngaphakathi kwezinkinga eziphuhlileyo ezingu-8 ezinhloko yezinkulungwane zezinhlanzi zombandla wamanzi kuzenzeka ngoba lezi ziphondo azange zihloliwe kungabi nokuba zimiselwe ngendlela engavumelekileyo. Lokhu kwenza ukuthi kutholeke kakhulu ukuthi kubalulekile kangakanani ukuhlanjulwa okunempilo kumsebenzi waphandle.

Izihlalo Ezibalulekileyo: Ukuphepha, Ukuqonda Kakhulu, Nokulandela I-Standards Zesi-IEC 61439

Lezi ziphando zilandelayo ziqhubeka ngamahlalo amathathu athile:

• UKUPHILA : Ukuqashwa kwezililo zokushisa kanye nokuchithwa kwesilinganiso ngaphambi kokuthi kugcine amandla
• Ukubonakala : Uqinisekisa ukulethwa kwegunya ngokuvamile phakathi kwemoto ezigcwele
• Ukuphumelela : Ukulandela i-IEC 61439 imitholampilo yobuchwepheshe nokunyuka kwezinkelinga (°70°C yebhasi ngaphandle kwegunya eligcwele)

Ukushaziwa kwezinkelinga kanye nezilinganiso zokuphula kancane kusetyenziswa ngakumbi yiindlela ezilungileyo ekugcineni lezi ziganeko ngokufanayo.

Indima yokuhlengahlenga ngexesha elide ekugcineni iqondo elipheleleyo lezihlangothi ze-Low Voltage

Iidatha ze-IEEE 2023 zibonisa ukuba uhlelo oluhleliweyo luhlengahlengo lukhupha ingcindezi yesiphazamo nge-62%. Ezinye iindlela ezibalulekileyo zikwazi kuzivavanyo zangonyana zezixhobo ezivuliweyo zezixhobo zokudibanisa i-busbar kwaye ukulungiswa ngokungabonakali ukuze kuboneke amagosa athetha ngaphaya. Iindawo ezilandelayo izigaba ezine-5 ngonyaka zokubuyisela i-circuit breakers zibonakala ukuba zineziphazamo ezingaphezu kwe-40% engafumanekanga kunazo ezingasebenzisiyo kuphela.

Imiyalelo yokuqala kanye nokulinganisa ubomi bokhuseleko phambi kokunika igunya kumathuba aphantsi kwegunya

Ukunciphisa ngempindo kanye nokugqiba ukulungiswa phambi kokunika igunya kumsimini

Conduct a comprehensive visual assessment of the low voltage panel, confirming:

• Akukho mthi noma ukungcono kumakhambi abusbar (uthuthukise ≥ 0.2 mm ubude besiko ngokwemibuzo yasikhathi yesivimba)
• Iziphazamiso ze-terminal zifanisane nezimiso zomkhiqizo (±5% isilinganiso)
• Amalabeli okunqoba nemkhawulo we-arc flash esigodini ngokulingana no-NFPA 70E

Ukuqinisekisa izilungiso zecircuit breaker ngexesha lokufakwa

Sebenzisa i-equipment ecaliwile ukuqinisekisa:

1. Izizathu ze-pickup ziqhelekile zifanisana nezimiso zokulungiselela (ngokuvamile 800–1200% yentlantla eqinisekisiweyo)
2. Izilungiso ze-long-delay zihambelana nentlantla yomgca olandelayo njengoko kuchazwe ku-NEC 240.4(D)

Izilungiso ezimbi zebreaker ngexesha lokuhlala kuseko zibangela i-34% yezimbi zenqanaba, ngokomfundo wa-2023.

Ukuyikhubaza nokubona ubungcwele bezintlu zokuphepha

Vula ukuphathelwa kwegonalo elumayo ngokusebenzisa imithombo ye-AC engu-50Hz, uqinisekisani ukuthi ukukhazimula akuphinde kube khona 0.1Ω ngokwesivumelwano sika-IEC 61439-1. Qinisekisani lo mlando:

• Ukusungulwa kokugcina kugcineka phakathi kwemizuzwana 0.5–1.5, kuvikelwa umthelela wokugcina ku-≤30V
• Amadoda ephaneli ane-lekheji yamandla angaphansi kuka-5mA ngenkathi kuchazwa ukukhazimula kwe-1000V DC
• Amajompi e-bonding ane-khazimula angaphansi kuka-0.01Ω phakathi kwezindawo zazojijwayo

Izivikelo ze-Core Electrical Ukubalwa Kwesimo se-Low Voltage Circuit Breaker

Ukubalwa okuhle kwezinyathelo zokugcina phansi kwezinyathelo kudinga izivikelo ezintathu eziphambene ukuthi kutholakale kwi-IEC 61439 ngelika esimiseni ubomi bokusebenza nobude bomthombo.

Ukuvikwa Kwezilimi Nokukhula Kwesimo Kuma Low Voltage Panels

Ukuvikwa kwesilimi kusetyenziswa i-megohmmeters ukubala ubume besilimi ngokumisa izimali zokulahleka. Ukuchazwa kwebume kusenziwa kuze kube khona 3.5 kV ukuthola izinkinga kwisilimi ngaphambi kokusebenza. Le ndlela ebalindelayo iyachazwa ukuthole izilinganiso eziphansi zokuvikwa ngemizatshana engcono futhi uqiniseke ubude bomthombo.

Ukuchaza Okusebenzayo Ngaphansi Kwezimo Ezibonakalayo

Ukuvavanya izililo nezimboni ngokufaka amandla aphezulu kune-300% yesilingo esingeniwe sibonisa indlela inqamuzana ivalela ngokushesha, njengoba yahlukile emehlweni ephuthumayo, ngapha kuka-50 milisekhenzi. Leli vavanyo libonisa futhi ukuthi kungaba kukhona ukusabela okuyinkimbili noma ukudluliswa kwamandla ekugcineni, libe lincike ezinhleleni zokuphatha izimboni.

Ukulungiswa Kwesixhobo Sokuvula Nokulinganisa KweNhlaka Yokuphendula

Ukulungiswa kwesixhobo sokuvula sezililo noma yedijithali kusivimba ukubambana okuhle phakathi kwezixhobo zokuphepha. Uvavanyo olwenzelwe ngokufaka amandla okuqala lubonisa ukulungiswa ngaphezu kwe-±3% ngokulinganayo nesikhashana sesikrini. Ukulungiswa okuhle kumviko izivalelo ezingalindelekile ngelinye ihlenze lokucima kungcono kuma-0.5 kuphela ngemva kokunyuka kwezililo.

Ukulinganisa Kwezinsuku Ezilandelwayo: Ukuhlelwa Kwesilingo Nokuvavanya Kwezimali Zomlando

Ubukhona Bekhanda Ngemvavanyo Yezililo Ukulungiswa Kwizinsuku Ezilandelwayo

Kukhona ukuthi kudingekile ukufaka izivimba ezihlala zisebenza ukuqinisekisa izinkinga zovoltage nezinkinga zokulinganisa amandla. Ngaphandle kwezikhathi ezingenalo izivimba, ukuphatha okusekelwe kuzivimba kubonisa izinkinga zokuxhumana, uhlelo lwesayizi yesihlondolozi, nokulungiswa kwesixoxo. Izibhodi eziphathwayo ngama-75–100% wezimali ezinhloko zibonisa inkinga yokuthola iphatshelwe engaphezu kuka-40% (Ingcobo Yavali Amandla, 2023).

Ukumelela Ukuphazima Kwesivimba Kuzibhordi Zesivimba Esincane Ngenkathi Kusebenza

Ukuze uthole ubude bezivimba ngendlela efanelekileyo, faka izidingo eziphakeme kakhulu zezibhodi bethu futhi usebenzise i-voltmeter enjalo ephathelene nge-RMS ebekwe kizwa emaphakade amakhaya. Ngokwembono yezinhlobo zomlando, ukuphatha kufanele kube neminyaka yokuqhubeka nokuphazima okuphakeme ukuze kutholakale indlela engeke iphume ngcono. Kuzisistemu ze-400V, izindawo ezibalulekile zokumelela zingaba:

Amatheshwado Amaneqayo Kusuka KuHlinzeko Lwe-IEC 60364-6

I-IEC 60364-6 ichaza ukuthi izinkinga zovoltage kumele azilandele 3% kusukela ekhisini kuqala kude kaphakathi komphakathi, ngamatheshwado amaneqedwa angama-5%. Ukudlula kwalokhu kuyisikhathi esiningi kubonisa ukuthi izihlengahlenga zingaphansi kwebala, iziqhikizo ezilahlekile, noma ukungalingani kwefazi—olunye oluchazwa njengoba kuthinta 22% yezinhloso zepaneli yesivumelwano (Ukuhlolwa Kwemfanelelo Yenkazo, 2024).

Isibonelo: Ukuhlola Kwingcingo Eziphakade Yovoltage ePaneli Ephezulu Yokusebenza

Indawo yokusebenza yekhono yabelana ngingcingo engu-8.2% yovoltage ebandla lomkhondo we-250A ngexesha lokuphuhlisa. Ngemuva kokulandela imigomo yomsebenzi wokulungiselela, abasebenzi bakhangele iziqhikizo ezithile zabusbare neconductor yaneleyo engeyiyo. Imiyalo ekulungisezeni—ukuzama futhi ngokuphatha kwe-infrared nokwandisa ubungakanani be-conductor—yahlawula ingcingo ku-2.1% wayesebenza ngokushintshiselana kwezinzo ngo-9%.

Izixhobo Zodidi Nomthetho Wokulungiselela Okunikileyo KumaPaneli Aphazinywayo
