Ku bar sida loo isticmaalo foornada dhalaalidda induction
Ku bar sida loo shaqeeyo foornada dhalinta dhalaalaysa
Heerka bilawga ah ee foornada dhalaalaysiinta ee induction:
Kahor intaadan bilaabin, hubi in wareegga korantadu uu wanaagsan yahay, in qaybaha ay wax gaareen, in goob kasta oo xiriiri ay dabacsan tahay ama ay go’an tahay.
Ifafaale, haddii xaaladda kor ku xusan ay dhacdo, sahayda korontada waa la shidi karaa ka dib marka ciladda la tirtiro.
(1) U wac shaqaalaha substation-ka ee shaqada ku jira si ay u xidhaan golaha beddelka foornada dhalaalaysa, awood foornada dhalaalaysa induction, oo ay saxeexaan diiwaanka gudbinta awoodda;
(2) Xidho galoofyada oo xidh lixda furaha gacanta ee hoos yimaada golaha awooda qaybinta, oo fiirso in voltmeter-ka soo galaya ee guddidu uu la mid yahay korantada sahayda, iyo in danab saddex waji ah oo soo galaya loo baahan yahay in la dheellitiro;
(3) Ku bilow voltmeter-ka xariiqda soo socda ee golaha korantada si aad u muujiso korantada korontada, iftiinka tusaha korantada (jaallaha) waa shid, iyo iftiinka calaamada korontadu (casaan) waa shid, marka hore u rog awoodda awoodda korontadu dhanka saacadda ilaa meesha eber (ilaa dhamaadka), oo riix rogaha batoonka shaqada (cagaaran), iftiinka shaqada inverter-ka (cagaaran) waa shidan yahay, iyo tilmaame voltmeter DC ee guddiga albaabka waa inuu ka hooseeyaa miisaanka eber;
(4) Awood litir. Marka hore, wax yar u hagaaji awoodda potentiometer-ka saacadda. Wakhtigan, fiiro gaar ah u yeelo samaynta soo noqnoqoshada dhexdhexaadka ah oo maqal dhawaaqa foodhida, taas oo muujinaysa in tamarta soo noqnoqda dhexdhexaadka ah si guul leh loo bilaabay. Kaliya markaa potentiometer-ka awoodda ayaa loo oggolaan karaa inuu si tartiib ah ugu wareego jihada saacadda, oo uusan si degdeg ah u soo jiidin. Awood, kororta si tartiib ah u kordhi, haddii inta jeer ee IF aan wali la dhisin, dib u celi potentiometerka oo dib u bilow;
(5) Marka korontadu shido, haddii aysan jirin ama dhawaaq aan caadi ahayn oo soo noqnoqda dhexdhexaadka ah, waa in aan lagu qasbin in la bilaabo, markaa potentiometer-ka waa in dib loogu noqdaa saacad ka hor ilaa dhammaadka, ka dibna dib loo bilaabo. Haddii dhowr jeer ay guul darreysato, waa in la xiro oo la hubiyaa;
(6) Marxaladda bilawga ah ee rarida (marka si joogto ah loo dhejiyo birta birta ah), awoodda waa in lagu hagaajiyaa 2000kW, sidaas awgeed awoodda hagaajinta awoodda waa inay lahaataa margin (potentiometer waa in aan la hagaajin si buuxda) si looga hortago kororka degdega ah awoodda iyo hadda ay sabab u tahay habka loading Sare, taasoo keentay dhaawac Thyristor ah. Ka dib marka la dhammeeyo rarka, si tartiib ah u kordhi awoodda in ka badan 3000kW;
(7) Marxaladda dhexe iyo dambe ee dhalaalidda, awoodda waa in la dhimaa ilaa 2000kW (koronta la dhimay). Ka dib marka buuxinta la dhammeeyo, si tartiib ah u hagaaji awoodda in ka badan 3000kW si aad uga hortagto kororka degdega ah ee awoodda iyo hadda inta lagu jiro habka dallacaadda. Waxyeelada saamaynta thyristor;
(8) Haddii ay jiraan waxyaabo ku soo ururay foornada, si buuxda ha u hagaajin awoodda awoodda wakhtigan, hana ku shaqayn awood sare. Awoodda waa in lagu xakameeyaa 2000kW si looga hortago in birta birta ah ay si lama filaan ah ugu dhacdo foornada, taasoo keenaysa koror degdeg ah oo kororka iyo hadda ah. , U keenida waxyeelada saamaynta thyristor;
(9) Inta lagu jiro habka dhalaalidda, haddii nidaamku si lama filaan ah u socdo, waa inaad si taxadar leh u ogaataa sababta safarka, oo aad si taxadar leh u hubiso golaha korantada iyo nidaamka tamarta dhexdhexaadka ah ee qulqulka, cadaadiska caadiga ah, iyo calaamadaha shilalka. Dib ha u bilaabin korontada inta jeer ee dhexdhexaadka ah si indho la’aan ah. , Si looga hortago balaadhinta cilladda, taasoo keenaysa waxyeello nidaamka korantada, thyristor iyo guddiga weyn;
(10) Xidhiidhka caadiga ah ee ka dhexeeya hadda iyo danab marka korantada lagu hagaajiyo awood buuxda oo awood ah waa:
Haddii danab = danab DC x 1.3
Danab DC = danab xariiqda soo galaya x 1.3
Hadda DC = xariiqda soo socota ee hadda x 1.2
(11) Kadib markaad xaqiijiso in wax waliba caadi yihiin xidhitaanka ka dib, daldal calaamadda (gudbinta korontada) ee biriiga gacanta.
Heerka xidhitaanka foornada dhalaalka dhalaalaysa
(1) Marka hore u leexi awoodda potentiometer-ka gees ka gees ilaa dhamaadka. Marka mitirka DC-ga, voltmeter-ka DC, mitirka soo noqnoqda, voltmeter-ka soo noqnoqda dhexdhexaadka ah, iyo mitirka korantada ee golaha korontadu waa eber, riix badhanka joogsiga beddelka (casaan), Tusiyaha joogsiga beddelka iftiinka (casaan) waa shidan yahay.
(2) Soo deji lixda shixnad ee gacanta ee qaybta hoose ee golaha wasiiradda awood qaybinta, oo daldal calaamadda (korontada).
(3) Ogeysii shaqaalaha kabka shaqada si ay u gooyaan qalabka wax lagu shido oo ay ka jaraan dabka foornada dhalaalaysa ee induction.
(4) Inta lagu jiro hawlgalka sahayda korontadu, aaladaha korantada waa in la duubo lana kormeeraa sida loogu baahan yahay. Haddii la helo xaalado aan caadi ahayn, mishiinka waa in la dami oo sababta waa in isla markiiba la hubiyaa, qaliinkana waa la sii wadi karaa ka dib marka cilada la tirtiro.
(5) Inta lagu guda jiro hawlgalka sahayda inverter-ka, haddii biyaha daadsan ama xannibaadda laga helo marin-biyoodka iyo qaybaha biyaha qaboojinta, mishiinka waa in la dami oo la hubiyaa oo wax laga qabtaa. Kadib hagaajinta iyo qalajinta timaha qalajiyaha, waa la shidi karaa oo mar kale ayaa la isticmaali karaa.
(6) Inta lagu jiro hawlgalka sahayda korontadu, waxaa si adag loo mamnuucay in la sameeyo indho-indheyn leexin, taabasho foorarsi, iyo hawlo quudin oo koronto leh. Hawlgallada kor ku xusan waa in la sameeyaa ka dib marka la joojiyo sahayda korontadu.
