Transformer ke sesebelisoa se tsitsitseng se fetolang matla a motlakase a AC ho tloha ho voltage e le 'ngoe ho ea ho e' ngoe ho boloka maqhubu a tšoana ka molao-motheo oa motlakase oa motlakase.
Lintho tse kenang ho transformer le tse tsoang ho transformer ka bobeli ke bongata bo fapaneng (AC). Matla a motlakase a hlahisoa le ho fetisoa ka matla a phahameng haholo. Ka nako eo motlakase o lokela ho fokotsoa hore o be boleng bo tlaase bakeng sa tšebeliso ea oona ea malapeng le ea indasteri. Ha transformer e fetola boemo ba voltage, e fetola boemo ba hajoale le eona.
Molao-motheo oa ho Sebetsa
Maqhubu a mantlha a hokahane le phepelo e le 'ngoe ea phase ac, ac current e qala ho phalla ho eona. Ac primary current e hlahisa phallo e fapaneng (Ф) bohareng. Bongata ba phallo ena e fetohang e amahanngoa le matsoelintsoeke a bobeli ho ea bohareng.
Ho feto-fetoha ha maemo ho tla kenya motlakase sebakeng sa bobeli ho latela melao ea faraday ea induction ea motlakase. Boemo ba motlakase bo fetoha empa khafetsa, ke hore, nako e lula e tšoana. Ha ho na khokahano ea motlakase lipakeng tsa mapheo a mabeli, matla a motlakase a fetisoa ho tloha ho mantlha ho ea ho a bobeli.
Transformer e bonolo e na le li-conductors tse peli tsa motlakase tse bitsoang primary winding le secondary winding. Matla a hokahana lipakeng tsa mapheo ka nako e fapaneng ea matla a khoheli a fetang (lihokelo) ka bobeli mapheong a mantlha le a bobeli.
Lisebelisoa tsa Bohlokoa tsa Transformer ea Matla
1.Buchholz relay
Relay ena e etselitsoe ho bona phoso ea kahare ea transformer mohatong oa pele ho qoba ho senyeha ho hoholo. Karolo e ka holimo ea phaphamala e potoloha le ho chencha mabitso ho koala 'me e fana ka alamo.
2.Oil Surge Relay
Relay ena e ka hlahlojoa ka ho tobetsa konopo ea teko e fanoeng ka holimo. Mona ho fanoe ka lebitso le le leng feela le fanang ka pontšo ea leeto mabapi le ts'ebetso ea float. Ka ho khutsufatsa ho ikopanya le kantle ka sehokelo, potoloho ea maeto le eona e ka hlahlojoa.
3.Leqhubu la ho phatloha
E na le phala e kobehileng e nang le diaphragm ea Bakelite lintlheng tse peli. Mesh ea terata e sirelletsang e kentsoe pulong ea transformer ho thibela likotoana tsa diaphragm tse phatlohileng ho kena ka tankeng.
4.Khatello ea Phallo ea Khatello
Ha khatello e ka tankeng e phahama ho feta moeli o sireletsehileng o boletsoeng esale pele, valve ena e sebetsa le ho etsa mesebetsi e latelang: -
E lumella khatello ho theoha ka ho bula boema-kepe hanghang.
E fana ka pontšo ea ts'ebetso ea valve ka ho phahamisa folakha.
E sebetsa ka micro switch, e fanang ka taelo ea maeto ho breaker.
5.Oil Temperature Indicator
Ke thermometer ea mofuta oa ho daela, e sebetsa ho latela molao-motheo oa khatello ea mouoane. E boetse e tsejoa e le magnetic oil gauge (MOG). E na le para ea makenete. Lerako la tšepe la tanka ea conservator le arola limakete ntle le ho kena ka lesoba.
6.Winding Temperature Indicator
E boetse e tšoana le OTI empa e na le liphetoho tse itseng. E na le probe e kentsoeng ka li-capillaries tse 2. Li-capillaries li hokahane le melumo e 'meli e arohaneng (ea ts'ebetso / ea ho lefella). Li-bellows tsena li hokahane le sesupo sa mocheso.
7.Moboloki
Ha ho atolosoa le ho honyela ho etsahala ka har'a tanka e kholo ea transformer, ka lebaka leo liketsahalo tse tšoanang li etsahala ka har'a conservator kaha e hokahantsoe le tanka e kholo ka phala.
8.Moena
Ena ke sefe e khethehileng ea moea e kenyelletsang lintho tse senyang metsi, tse bitsoang, Silica Gel. E sebelisetsoa ho thibela ho kenella ha mongobo le moea o silafetseng ka har'a conservator.
9.Radiators
Li-transformer tse nyane li fanoa ka li-tubes tse pholileng tse cheselitsoeng kapa li-radiator tsa tšepe tse hatelitsoeng. Empa li-transformer tse kholo li fanoa ka li-radiator tse senyehang hammoho le li-valve. Bakeng sa pholileng e eketsehileng, ho fanoa ka li-fan exhaust ho li-radiator.
10.Tlanya Changer
Ha mojaro ho transformer e ntse e eketseha, motlakase oa bobeli o fokotseha.Ho na le mefuta e 'meli ea phetoho ea pompo.
A.Off Load Tap Changer
Ka mofuta ona, pele o tsamaisa mokhethoa, transformer e entsoe OFF ho tloha lipheletsong tse peli. Lisebelisoa tse joalo tsa lipompo li na le likhokahano tse tsitsitseng tsa koporo, moo lipompo li felisitsoeng. Mabitso a tsamaeang a entsoe ka koporo ka sebopeho sa rolara kapa karolo.
B.On Load Tap Changer
Ka bokhutšoanyane re e bitsa OLTC. Ho sena, lipompo li ka fetoloa ka letsoho ka ts'ebetso ea mochini kapa ea motlakase ntle le ho tima transformer. Bakeng sa ts'ebetso ea mochini, li-interlock li fanoa bakeng sa ho se sebetse ha OLTC ka tlase ho boemo bo tlase ba theipi le boemo bo phahameng ka ho fetisisa ba ho theipi.
11.RTCC (khubicle ea taolo ea pompo e hole)
E sebelisetsoa ho fetola lipompo ka letsoho kapa ka boiketsetso ka Automatic Voltage Relay (AVR) e behiloeng +/- 5% ea 110 Volt (Reference e nkiloeng lehlakoreng la bobeli la PT voltage).
