02 Kev tsim khoom
2.1 Core
Cov tub ntxhais yog precision-ua nrog siab-qib, txias- dov nplej- taw qhia silicon steel. Cov khoom siv no, nrog rau kev tsim laminated qib siab, txo qis kev sib nqus thiab lub zog tam sim no. Nws txoj kev tsim kho ruaj khov ua kom muaj suab nrov tsawg thiab lub zog siv tshuab, muab txoj hauv kev ruaj khov thiab muaj txiaj ntsig zoo sib nqus uas yog qhov tseem ceeb rau kev hloov pauv kev ntseeg tau thiab kev ua haujlwm.
2.2 Cua txias
Cov windings yog optimally tsim rau kev ua tau zoo thiab kev ntseeg tau. Qhov qis-voltage winding siv cov ntawv ci- tsim qhov txhab, muab cov neeg kho tshuab zoo heev, ua kom muaj cua sov zoo dua, thiab luv luv - Circuit Court muaj peev xwm. Ua kom tiav nws, qhov siab -voltage winding ntiav cov txheej txheem precision- cov txheej txheem mob nrog kev sib cuam tshuam zoo -tig rwb thaiv tsev, kom ntseeg tau qhov hloov pauv qhov tseeb thiab lub zog dielectric zog. Qhov kev sib xyaw ua pov thawj no muab kev ua haujlwm tshwj xeeb, ruaj khov, thiab kav ntev.
2.3 Tank
Lub tank yog ib qho ruaj khov, welded steel qauv tsim los rau kev ua haujlwm ntev thiab kev ua haujlwm. Nws ua hauj lwm raws li ib tug tiv thaiv enclosure rau cov tub ntxhais thiab windings, muab ib tug kaw reservoir rau insulating kua, thiab nta radiators kom zoo cua sov dissipation. Engineered los tiv thaiv ib puag ncig thiab kev ua haujlwm kev ntxhov siab, lub tank ua kom lub tshuab hloov lub sijhawm ntev - kev ncaj ncees thiab kev ntseeg tau.
2.4 Lub Rooj Sib Tham Kawg
Kev sib dhos zaum kawg yog kev sib koom ua ke ntawm cov tub ntxhais, windings, tank, thiab cov khoom siv rau hauv kev sib koom ua ke thiab muaj zog. Lub sijhawm tseem ceeb no ua kom txhua qhov kev sib txuas hluav taws xob sab hauv tau ruaj ntseg, cov khoom siv tshuab muaj suab nrov, thiab lub kaw lus kaw zoo kawg nkaus. Qhov tshwm sim yog qhov ua tiav ntawm tus kheej -muaj, npaj tau- rau- lub zog ua haujlwm uas muab cov qauv tsim, ua haujlwm ntev, thiab kev ntseeg tau.
