Transformer hadda
Transformer-ka hadda (CT-ga oo gaaban) waa aaladda wareejin karta oo cabbiri karta hadda iyadoo la raacayo mabda'a soo-saarka korantada.
Noocan qalalan ee CT ee la soo saaray wuxuu ka kooban yahay dabaysha aasaasiga ah, galka dibadda, qaab dhismeedka dahaarka awoodda leh, dallad caag silikoon ah oo isku dheelli tiran daboolka labada daraf, qolof, dabaylo sare iyo fiilada fidinta.
Iyada oo faa'iidooyinka ugu sarreeya ee aan saliid-buuxinta lahayn, aan lahayn gaas-buuxinta, aan lahayn boorsada, mugga yar, miisaanka fudud, culeyska shaqada yar ee dayactirka, dabka iyo ilaalinta qaraxa, CT-ga nooca qalalan ayaa si degdeg ah oo ballaaran loogu caanbaxay Shiinaha. Iyo iyadoo ay ugu wacan tahay sinnaanta qaybinta danabyada dusha sare iyo isticmaalka walax caag silikoon ah sida dahaarka dibadda, waxay sii wanaajin kartaa korontada wasakhaysan.
Nooca: taxanaha LG.
Muhiimada nooca badeecada sida soo socota:
LG
Danab la qiimeeyay, unugga: kV
Qalalan nooca qallalan ee hadda jira oo leh gariiradda ilaalinta
Sida:
LG-110: danab lagu qiimeeyay 110 kv, nooca qalalan ee hadda jira oo leh gariiradda ilaalinta. LG-220: danab lagu qiimeeyay 220 kv, nooca qalalan ee hadda jira oo leh gariiradda ilaalinta.

Xaaladaha Adeegyada
1. Gaadiidka
1.1 Badeecadaha waxay isticmaali karaan tareenada, markabka, baabuurta iyo diyaaradaha iwm. baabuurta si ay u qaadaan, gawaarida tareenada, qolka uumiga iyo gawaarida gawaarida waa inay ahaadaan kuwo nadiif ah oo aan wasakh ahayn.
1.2 Alaabooyinka raritaanka xamuulka waa in ay waafaqaan shuruudaha qawaaniinta rarida, oo dhig alaabta si badbaado leh, oo aan loo ogolayn inay ka dhex muuqdaan gaadiidka gariir, shil iyo dhaqaaq.
1.3 Alaabooyinka ku jira habka gaadiidka, gradient waa in aanay ka badnayn 30 °. 1.4 Alaabta ku taal wareejinta dekeda ama ka bixista meesha loo socdo ma ogola in la is dul saaro.
2.Alaab-qaadista
2.1 Qalabka wax lagu qabto waxa uu isticmaali karaa wiish, wiishka xamuulka qaada ama fargeeto iwm. qalabka wax lagu qaado.
2.2 Marka rarista iyo dejinta waa in si adag loo waafajiyaa habraaca rarista iyo dejinta.
2.3 calaamada "Halkan kor u qaad" waxay ku taal afarta gees ee hoose ee sanduuqa xidhmada ee hoose. Marka wax la qaadayo, waa in ay ku jirtaa "halkan kor u qaad" xadhigga xadhigga ganaaxa. Sida sawirka ka muuqata:
2.4 Buufiska baakidhka Main dusha sare oo leh xarunta calaamadda cuf-jiidadka, haddii xarunta cuf-isjiidadka ay ka leexato booska dhexe si cad, marka la qaadayo, waa in la hagaajiyo dhererka xadhigga birta ah ee xadhigga ka dhigaya jillaab si toos ah u wajahaya xarunta sanduuqa culeyska.2.5 Habka rarista iyo dejinta badeecadaha, waa in si taxadar leh wax looga qabto.
Aqbalaada, haynta iyo kaydinta
1. Hubinta aqbalaadda
Ka dib markii la helo transformer-ka hadda, waa in ay isla markiiba hubisaa.
1.1 Hubi in uu waafaqsan yahay xogta taarikada alaabta iyo dalabka qandaraaska, sida moodelka alaabta, saamiga hadda la qiimeeyay, awoodda la qiimeeyay iwm.
1.2 Hubi faylka warshadda fasaxa haddii uu dhammaystiran yahay, haddii uu waafaqsan yahay heshiiska.
1.3 Hubi in qaybaha baakadeynta iyo agabka sanduuqa ku jira ay waafaqsan yihiin liiska baakadka.
Buug-hawleedka hadda jira ee beddelka
1.4 Hubi badeecada ku jirta gaadiidka in ay waxyeeleeyeen iyo in kale, in qaybaha alaabtu ay waxyeeleeyeen iyo baro kaca, fiilada xadhigga lagu dhejiyo in ay dabacsan yihiin, khalad, dahaarka haddii ay jabeen, wasakh ama jir shisheeye iwm.
1.5 Alaabta furan sanduuqa hubi, haddii aan isla markiiba la hawlgalin, waa in si sax ah loo hayaa ama dib loo baakadeeyaa, haddii ay dhacdo khasaare.
2. Bakhaarka & Dhigista
2.1 Haddii loo baahdo bakhaar iyo meel dhigid, baakaduhu waa in aan la dumin, haddii jeeg iyo aqbal baahida baakadeynta, jeegga ka dib oo aqbal waa in ay soo celiyaan baakadda.
2.2 Alaabta kaydinta muddada-dheer, waa in la hubiyo kaydinta bakhaarka, bakhaarku waa inuu ahaadaa mid nadiif ah, qalalan, waa in aan la kaydin isla mar ahaantaana kiimikooyinka firfircoon iyo walxaha daxalka.
2.3 Alaabooyinka looma oggola inay is dulsaaraan.
Hubinta Ogolaanshaha
1. Ka hor inta aan la rakibin waa in si taxadar leh u akhri faahfaahintan, magaca badeecada iyo alaabtu waxay qeexayaan sawirka cabbirka, fahmaan miisaanka alaabta, habka rakibidda iwm., u diyaari qalabka iyo qalabka u dhigma. Ka digtoonow ha xoqin marada dallada cinjirka silikoon. Habka kor u qaadista sida sawirka:
Ogow
1. 1Marka kor loo qaado, P1, P2 ee labada dhinac dhererka xadhiggu waa mid joogto ah, transformer ma soo jeedin karo. Haddii la helo u janjeera transformer waa in fiiro gaar ah si loo hagaajiyo dhererka xadhigga labada dhinac, ka dhigi ay dheellitiro.
1. 2Haddii xarunta Transformer ee cuf-jiidadka ay u janjeerto ama ka baxsan tahay baaxadda qolofka, waxay u baahan tahay in la hagaajiyo transformerka sare, sida dhanka bidix ee A, afarta xarig ee isku xiran, xagga kor u qaadista, iyo in la hubiyo in transformer-ka uusan qeyb ka ahayn. .
2. Guud ahaan, si toos ah ayaa loo dhigi karaa transformer-ka hadda ee booska isticmaalka, hubinta rakibidda ayaa la gelin karaa hawlgalka. On-site rakibidda boolal godka dalool waa in ay ahaataa tixraaca Transformer hadda sawir cabbir, oo u dhiganta in godka rakibaadda transformer hadda, iyada oo loo marayo boolka si loo hagaajiyo transformer hadda, ka hor inta hawlgalka waa earthing bool on qolof in xiriirka dhulka.
Dhammaan noocyada qaab dhismeedka rakibaadda transformer hadda:
