Ujeedada iyo habka tijaabada ee AC waxay u adkeysanaysaa tijaabada danabka ee transformerka

Transformer-ka AC ee u adkaysta tijaabada danabku waa tijaabo uu korantada imtixaamka korontada sinusoidal-ka AC ee ka badan dhawr jeer oo danab la qiimeeyay lagu dabaqo dabaylaha taransiibiyaha la tijaabiyay oo ay weheliso baadiyaha, muddadana waa 1 daqiiqo.Ujeeddadeedu waa in la isticmaalo koronto tijaabo ah oo ka sarreeya dhawr jeer oo danab la qiimeeyay si loogu beddelo korantada atmospheric-ka iyo kororka gudaha si loo qiimeeyo waxqabadka dahaadhka beddelka.Waa hab wax ku ool ah oo lagu garto awoodda dahaarka ee Transformers, sidoo kale waa shay tijaabo ah oo muhiim ah si loo hubiyo in ay si badbaado leh u shaqeeyaan transformers loogana fogaado shilalka dahaarka.Samaynta tijaabooyinka korantada ee AC waxay ka heli kartaa qoyaan iyo cilado xoog leh oo ku jira dahaarka ugu weyn ee transformer, sida dabaylaha dillaaca dahaadhka muhiimka ah, dabciga dabaysha iyo barokaca

Tijaabada korantada ee AC waa tijaabo wax burburisa tijaabada dahaarka.Waa in la tijaabiyaa ka dib marka la eego tijaabooyinka kale ee aan burburin (sida iska caabbinta dahaarka iyo tijaabada saamiga nuugista, tijaabada leakage DC, goynta luminta dielectric lumis iyo tijaabada saliidda dahaadhka) ayaa u qalma..Kadib marka tijaabadan loo qalmo, transformer-ka waa la shaqayn karaa.Tijaabada korantada AC waa imtixaan muhiim ah.Sidaa darteed, xeerarka tijaabada ka-hortagga ah waxay qeexayaan in transformer-ka leh 10kV iyo wixii ka hooseeya, 1 ~ 5 sano, 66kV iyo wixii ka hooseeya, waa in lagu dhejiyo AC u adkaysta korantada ka dib dib-u-hagaajinta, ka dib beddelka dabaylaha iyo marka loo baahdo baaritaanka.

Habka tijaabada

(1) Tijaabada fiilooyinka korantada yar yar iyo kuwa dhexe ee ka hooseeya 35kV waxaa lagu dabaqaa fiilooyin tijaabinta AC.Dhammaan dabaylaha waa in la tijaabiyaa.Inta lagu jiro tijaabada, fiilooyinka rasaasta weji kasta waa in ay noqdaan kuwo gaaban oo wada socda.Haddii barta dhexdhexaadka ah ay leedahay fiilooyinka rasaasta, fiilooyinka rasaasta waa in sidoo kale ay noqdaan kuwo gaaban oo leh saddexda weji.

(2) Tijaabada danab Halbeegga tijaabada xil-wareejinta wuxuu dhigayaa in Transformers-ka awoodda ka hooseeya 8000kV iyo korantada lagu qiimeeyay dabaysha ee ka hooseysa 110kV waa in la mariyaa tijaabada tamarta adkaysiga AC iyadoo la raacayo heerarka korantada tijaabada ee ku qoran lifaaqa 1 ee heerka.Xeerarka tijaabada ka hortagga ah ayaa qeexaya: Qiimaha korantada tijaabada ee transformer-ka saliidda lagu shubay ayaa lagu faahfaahiyay shaxda sharciyeynta (tijaabada joogtada ahi waxay beddeshaa qiimaha korantada qayb ahaan).Transformers-ka nooca engegan, marka dhammaan dabaylaha la beddelo, raac qiimaha korantada tijaabada warshadda;Beddelka qayb ahaan dabaylaha iyo tijaabooyinka caadiga ah, riix 0.85 jeer qiimaha tamarta tijaabada warshadda.

(3) Taxadirka Marka lagu daro taxadirka tijaabada guud ee AC ee u adkeysanaya korantada, qodobada soo socda waa in la xuso iyadoo loo eegayo sifooyinka transformerka:

1) Transformer-ka tijaabada ah waa in lagu rakibaa qalabka safarka ee ilaalinta xad dhaafka ah.

2) AC-ku-tijaabada korantada ee saddex waji uma baahna in lagu sameeyo wejiyo.Si kastaba ha noqotee, dhammaan fiilooyinka rasaasta ee saddexda weji ee dabaysha midaysan waa inay ahaadaan kuwo gaaban oo wareega imtixaanka ka hor, haddii kale ma saameyn doonto oo kaliya saxnaanta tamarta tijaabada, laakiin waxay xitaa halis gelin kartaa dahaarka ugu weyn ee transformer-ka.

3) Xeerarka tijaabada ka hortagga ah ayaa tilmaamaya in dhammaan transformers-yada dahaaran ee ka hooseeya 66kV, marka xaaladaha goobta aan la heli karin, kaliya inta jeer ee dhismaha dibadda ah ee u adkeysiga tijaabada korantada ayaa la samayn karaa.

4)Transformers-ka korantada ee dahaarka dhibicda dhexdhexaadka ah uu ka daciifsan yahay qaybaha kale ama dahaarka darajada sare leh, AC-ga sare ee dibadda ee ka soo baxa tijaabada korantada lama isticmaali karo, laakiin induction adkeysi danab ah 1.3 jeer waa in la isticmaalaa.

5) Waa in la tijaabiyaa ka dib marka lagu shubo saliid tayo leh oo lagu nasto muddo cayiman.

6) Transformers-yada dhexdhexaadka ah iyo kuwa yar-yar ee leh heerka korantada ee 35kV, korantada tijaabada waxaa loo oggol yahay in lagu cabbiro dhinaca korantada hoose ee beddelka tijaabada.Transformers koronto leh awood weyn, si cabbirka looga dhigo mid sax ah oo la isku halayn karo, waa in la isticmaalo koronto-dhaliyaha ama voltmeter-ka korantada.Korontada tijaabada waxaa si toos ah loo cabbiraa dhinaca tamarta sare.

7) Haddii dheecaanku ama burburku dhaco inta lagu jiro tijaabada, isla markiiba hoos u dhig tamarta oo jar korontada si aad uga fogaato fashilka weyn.
