02 Kev tsim khoom
2.1 Core
Lub 500 kVA 3-theem faib transformer muaj peb-theem peb-limb core ua los ntawm high-qib txias-silicon steel. Nws muab qis tsis muaj-load poob thiab suab nrov tsawg. Cov tub ntxhais siv cov lamination meej thiab cov kauj ruam-plab pob qij txha kom txo cov hlau nplaum tiv thaiv. Cov qauv clamping pab txo kev vibration. Qhov kev tsim no ua rau lub transformer ua haujlwm zoo dua thiab ruaj khov thaum lub sijhawm ua haujlwm ntev.
2.2 Cua txias
Cov windings yog ua los ntawm high -conductivity aluminium nrog txheej winding. Lawv siv Class H rwb thaiv tsev thiab nruj winding khoob los txhim kho lub zog dielectric. Aluminium winding muab cov cua kub zoo thiab muaj zog tiv thaiv luv luv - lub zog hluav taws xob. Nws kuj ua rau lub transformer sib dua thiab txhim kho kev ua haujlwm kub.
2.3 Tank
Lub tank yog tag nrho welded steel qauv nrog ONAN ntuj roj txias. Qhov saum npoo yog sandblasted, ces coated nrog primer thiab epoxy xim rau muaj zog corrosion tiv thaiv. Qhov kev tsim no ua rau lub transformer txhim khu kev qha hauv kev siv sab nraum zoov thiab kev lag luam.
2.4 Kev sib dhos zaum kawg
Cov tub ntxhais thiab cov coil sib dhos yog ntxuav, tshuaj xyuas, thiab ua tib zoo ua raws, nrog aluminium windings securely clamped thiab insulated. Thaum lub sij hawm tanking, lub active ib feem yog muab tso rau hauv ib tug huv si tank, grounded, thiab zoo positioned rau stability.
Cov khoom siv xws li siab- thiab qis-voltage bushings, radiators, pressure relief valve, lifting lugs, thiab off-circuit tap changer are installed and sealed. Cov khoom siv ntxiv muaj xws li bayonet fuse nrog CLFs, 2- txoj haujlwm LBOR hloov, ntsuas qib ua kua, ntsuas lub tshuab nqus tsev siab, tus ntsuas kub dial, thiab lub ntsuas dej thiab cov qauv valve.
Lub tshuab nqus tsev vacuum - puv nrog cov roj ntxhia, kuaj xyuas qhov kev sib khi, thiab kuaj xyuas hluav taws xob, suav nrog kev ua haujlwm, qhov sib piv, qhov hluav taws xob tiv thaiv, rwb thaiv tsev, thiab kev ntsuas hluav taws xob. Tom qab kev ntxuav thiab tshuaj xyuas zaum kawg, cov ntaub ntawv teev npe thiab cov cim raug txheeb xyuas ua ntej xa khoom xa tuaj.
