Xeerarka Voltage of Transformer

 

Transformer-ku wuxuu u baahan yahay nidaaminta korantada inta badan sababtoo ah isbedbedelka korantada korantada iyo isbeddelka culeyska ayaa u horseedi doona xasilooni darada korantada labaad, sidaas darteed saameynaya hawlgalka caadiga ah ee qalabka korantada, ujeedada xakamaynta danabku waa in la dejiyo tamarta wax soo saarka.

 

• Saamaynta isbedbedelka danabka

• Korontada ku jirta shabkada ma aha mid joogto ah oo way isbedbedeli doontaa sababo kala duwan awgood (sida dhererka khadka sahayda, isbeddelka tamarta sahayda, iwm.). Isbeddelkaani wuxuu keeni doonaa in danabka dhinaca labaad ee Transformer-ka uu is beddelo, haddii danabku uu sarreeyo ama hooseeyo, waxaa laga yaabaa inay waxyeello u geystaan ​​qalabka korontada ama waxay ka dhigi karaan inay si caadi ah u shaqeeyaan.

• Saamaynta rarka isbeddelka

• Cabbirrada kala duwan ee culeyska iyo qodobbada awoodda ee ku xiran dhinaca labaad ee beddelka ayaa sidoo kale keeni doona isbeddel ku yimaada tamarta sare. Tusaale ahaan, haddii culeyska ka jira meel gaar ah uu si lama filaan ah u kordho, oo korantada wax soo saarka ee Transformer-ka aan loo hagaajin si waafaqsan, waxaa dhici karta in koronta aagga ay hoos u dhacdo, taas oo saameynaysa shaqada caadiga ah ee qalabka.

 

 

2.1 Qeexid

Kala duwanaanshaha nidaaminta korantada waxaa loola jeedaa faraqa u dhexeeya qiimaha ugu sarreeya iyo kan ugu yar ee taransfooriyuhu hagaajin karo iyadoo lagu salaynayo danabtiisa la qiimeeyay, inta badan waxaa lagu muujiyaa sida boqolkiiba. Beddelka booska beddelaha tuubada, taransiibiyuhu waxa uu hagaajin karaa danab ku dhex jira xadka nidaaminta danab si uu u daboolo baahiyaha nidaamka korantada ama culayska.

 

2.2 Habka Hadalka

• Matalaadda boqolkiiba

Baaxadda korantada waxaa badanaa lagu muujiyaa sida boqolkiiba tamarta la qiimeeyay. Tusaale ahaan, qiyaasta nidaaminta korantada ee ± 2 * 2.5% waxay ka dhigan tahay in korantada transformer-ka la kordhin karo ama la dhimi karo 5% laga bilaabo tamarta la qiimeeyay.

• Tirada qasabadaha

Meelo kala duwan oo ku yaal tuubada-bedelaha waxay u dhigmaan koronto kala duwan, boos kastana waxaa loo yaqaan 'Tap'. Kala duwanaanshaha nidaaminta korantada waxaa lagu go'aamiyaa meesha ay ku yaalliin qasabadahan.

• Qiimaha korantada ee gaarka ah

Kala duwanaanshaha danab sidoo kale waxaa lagu muujin karaa qiimo gaar ah. Tusaale ahaan, Transformer leh danab lagu qiimeeyay 110kV waxaa lagu hagaajin karaa inta u dhaxaysa 99kV iyo 121kV haddii qiyaasta nidaaminta korantadu ay tahay ± 10%.

 

 

Isku soo wada duuboo

Cabbirka tallabada marsho kasta (tubadu) waa 2.5%, oo leh qalabka la qiimeeyay (qalabka 9aad) oo ah gear-gii hore, si togan 8 gear, 2.5% gearkiiba, ilaa 8 gear taban, 2.5% gearkiiba, wadar ahaan 17 Gear, kala duwanaanshaha guud ee nidaamka korantada ee ± 10%, oo u qoran sida ± 8*1.25%

 

 

3.1 Xeerarka Korantada-Load-la'aanta (NLTC)

Qeexid

Si aad ugu habboonaato hagaajinta taab-bedeliyaha marka uusan taransfooriyuhu noolayn. Habkan nidaaminta danabku wuxuu u baahan yahay in la fuliyo marka labada dhinac ee aasaasiga ah iyo kan sare ee transformer-ka ay ka go'aan shabagga

Magaca Ingiriisiga

Beddelaha tuubada aan rararka lahayn (NLTC)

Beddelka tuubada-wareega ka baxsan (OCTC)

Bedelka tamarta laga jaray (DETC)

Qiyaasta nidaaminta korantada

Xeerarka korantada guud ee aan culeyska lahayn waa ± 2 * 2.5%, 5 heerar

 

 

3.2 Ku beddelka tabaha ku shubida (OLTC)

Qeexid

Nidaaminta korantada korka saaran waa hab nidaaminta danabka oo beddeli kara danabka iyadoo beddeleysa qalabka tuubada marka uu taransfooriyuhu ku socdo culeyska.

Magaca Ingiriisiga:

Beddelka tuubada-saaran (OLTC)

Ku shub beddelka tuubada (LTC)

Qiyaasta nidaaminta korantada

Baaxadda ayaa aad u weyn, sida ± 8 * 1.25%, 17 hagaajinta cadaadiska marsho, ama ka weyn, sida 21 gear

 

3.3 Qaybaha shididda rarista

Jidhka beddel

• Waxay ku taallaa gudaha haanta, dabaysha isku xidhan ee xakamaynta cadaadiska

Nooca

Shidaalka lagu shubo (Nooca Saliida)

• Saliida lagu dhex shubay rarka saarani waxay u isticmaashaa saliid transformer sida dahaarka iyo daminta dhexdhexaadka ah. Marka uu daaranuhu damiyo tuubada, saliidda waxa lagu daminayaa hababka jidhka iyo kiimikaad.

• Qiimaha jaban, gudaha ilaa 6W, sida Shanghai Huaming, la soo dejiyo waxa laga yaabaa inay 5-6 jeer ka badan tahay qiimaha, sida Germany MR, Sweden ABB iyo wixii la mid ah

Vacuum switch (nooca vacuum)

• Xakamaynta korantada saaran vacuum waxa ay isticmaashaa vacuum discer. Marka qasabadaha la beddelayo, qaansada si degdeg ah ayaa loo bakhtiiyaa jawi faaruq ah.

• Qiimaha sare, gudaha qiyaastii 21W, sida Shanghai Huaming, la soo dejiyo waxay noqon kartaa {1} jeer qiimaha, sida Germany MR, Sweden ABB iyo wixii la mid ah

 

 

Unug kaxaynta matoorka

• Waxay mas'uul ka tahay in ay waddo furaha si ay u dhammaystirto beddelka tuubada. Habka korantada wuxuu ka kooban yahay matoorrada, gawaarida gawaarida, nidaamyada xakamaynta, iwm, si loo gaaro kontoroolka maxalliga ah iyo kantaroolka fogaanta.

• Voltage motor: 400VAC caadiga ah, sidoo kale laga yaabaa in kale, sida waafaqsan shuruudaha macaamiisha

 

 

AVR (Automatic Voltage Regulator)

AVR-ku wuxuu ogaadaa farqiga u dhexeeya danabka wax soo saarka iyo qiimaha go'an wuxuuna si toos ah u hagaajiyaa kicinta hadda ama booska tuubada si loo ilaaliyo xasilloonida korantada wax soo saarka.

 

 

Golaha kontoroolka qalabka fogfog (RTCC)

Kormeerka fog ee cadaadiska transformer-ka, heerkulka, gaaska gaaska iyo calaamadaha kale iyo sidoo kale nidaaminta korantada
