6 Beddeleyaasha Tareennada ee MVA-22/1.22 kV|Koonfur Afrika 2023

01 Guud

1.1 Asalkii Mashruuca

Tani 6MVAtransformer jiidwaxaa loo dhoofiyaa Koonfur Afrika Agoosto 2024. Kooxda ka kooban taransfooriyahan waa Y/d11y0y0n. Korantada aasaasiga ah waa 22 kV, korantada sare waa 2 * 1.22＋1.22 kV, transformer-ku wuxuu ku qalabaysan yahay wax bedela rarka, cabirka taabashadu waa ± 2 * 2.5% dhanka hoose, qaboojinta waa ONAN.

Transformers-yada tareenada waxaa loogu talagalay in lagu yareeyo saameynta faragelinta iswaafajinta. Marka Transformer-ku uu si joogto ah u buuxo culeyska, kor u kaca heerkulka taransfooriyaha ee dabaysha ka dib dheellitirnaanta kulaylka iyo heerkulka xasilan kama badna 65 darajo C, kama badna 70 darajo C oo ka yar 3 jeer culeyska hal daqiiqo gudaheed, kama badna 70 darajo C oo ka hooseeya 10 ilbiriqsi 3.5 jeer culeyska, mana dhaafo 100 digrii C ka hooseeya 2 jeer culeyska 30 daqiiqo. Transformer-ku waxa uu ku qalabaysan yahay relay kulaylka xad dhaafka ah si uu u ilaaliyo culayska badan ee taransfooriyaha iyada oo la raacayo magdhowga heerkulka jawiga iyo xidhiidhka goynta. Transformer-ku waxa uu ku qalabaysan yahay raadiyeer go'i kara. Hidiyeetiyuhu waxa uu qaataa hannaan kulul oo gaar ah{13}}oo dusha sare ee hiitarka waa la rinjiyeeyay oo la dahaadhay. Transformer-ku wuxuu u adkeysan karaa 3.5 jeer culeyska.

02 Wax-soo-saarka

2.1 Core

Qaab dhismeedka:

● Waxay ka kooban tahay saddex lugood oo toosan iyo harqoodyo sare iyo hoose, samaynta wareegga magnetka xiran.

● Lug kastaa waxay wadataa hal weji dabaysha, iyada oo hubinaysa in saddex waji - wadooyin magnetic ah.

Qalab:

● Waxa laga sameeyay birta silikoon ee saraysa ee lagu dahaadhay faashashka dahaarka si loo yareeyo khasaaraha hadda jira iyo xiiqdheerta.

Waxqabadka:

● Qaybinta qulqulka magnetic waa isku mid, oo leh qulqulka qulqulka ugu yar iyo waxtarka sare.

● Hababka qaboojinta sida caadiga ah waxaa ka mid ah qaboojinta saliidda ama qaboojinta hawada, oo leh qaab dhismeed deggan iyo iska caabin gariir aad u fiican.

2.2 Dabaylaha

Isku xirka: Y/d11y0y0n (Awoodda dabaysha saddexaad ee danab hoose 150kVA)

Dabaylaha danab sare: xidhiidhka xiddiga

Dabaylaha hoose ee korantada hoose: Xidhiidhka xagasha

Dabaylaha sare ee danab hoose: xidhidhiyaha xiddiga

Low- dabaylaha korantada ee hooseeya: Dhinaca labaad ee transformerku waxa uu bixiyaa saddex{1}} wejiga saddexaad ee dabaysha si uu koronto u siiyo transformerka kaaliyaha, iyo dabaysha saddexaad waxa si toos ah looga taaban karaa dabaysha sare ama dabaylaha saddexaad ayaa si gaar ah loo samayn karaa. Dabaylaha saddexaad waa inuu lahaadaa gacmo gooni ah, kaas oo awood siin kara beddelka kaaliyaha. Transformer-ka caawiye waa 150kVA.

Xadka kor u kaca heerkulka:

Culays buuxa oo joogto ah, kor u kaca heerkulka beddelka waa in aanu dhaafin 65 digrii C ka dib dheellitirka kulaylka iyo heerkulka deggan.

1 daqiiqo 3 jeer culaysku kama dhaafo 70 digrii

10 ilbiriqsi 3.5 jeer culaysku kama dhaafo 70 digrii C

30 daqiiqo 2 jeer culaysku kama dhaafo 100 digrii C

Danab yar oo saddexaad oo dabaysha 1.22kV, awoodda 150kVA, oo leh bar dhexdhexaad ah

Dabaysha tamarta sare waxay qabataa dabaysha saxan ee joogtada ah iyo dabaysha danyarta yar waxay qabataa dabaylaha wareegsan

Dhammaan dabaylaha ayaa si buuxda u dahaaran

Transformer-ka ayaa loo adeegsadaa goobta ay biriqda daran ku dhufatay, waxaana danab-qabtaha lagu rakibay inta u dhaxaysa baska danabkiisu sarreeyo iyo dhulka hoose ee saldhiga.

Dabaylaha Transformer-ku waxay leeyihiin awood farsamo oo ku filan si ay uga hortagaan qulqulka cilada leh

2.3 Haanta

Haanta waxay ka samaysan tahay saxan bir ah oo ka weyn ama la mid ah 6mm

Dhumucda saxanka hoose ee haanta 16mm

Transformer taangiga cawl, barkin saliid cad, dhumucdiisuna tahay rinjiga ugu yaraan 125 microns

Taangiga shidaalka ee ugu weyn, waxaa ku yaal tuubo ku taal dhinaca barkinta iyo dhinaca ka soo horjeeda ee isku xirka shaandhada saliidda, dhererku wuxuu ku habboon yahay hawlgalka dhulka, dhinac wuxuu ku yaalaa meel sare, dhinaca kalena wuxuu ku yaalaa meel hoose (haddii loo baahdo, dhinacan waxaa lagu dari karaa tuubada saliidda) tuubada waxay leedahay 50mm dun gudaha ah.
