02 Kev tsim khoom
2.1 Core
SCOTECH cores yog tsim nyob rau hauv kev tswj hwm nruj, kom ntseeg tau cov txheej txheem sib dhos, cov txheej txheem lamination siab, thiab sib nqus sib nqus. Cov txheej txheem no ua tau zoo txo qhov sib txawv ntawm huab cua thiab kev siv tshuab ua haujlwm nyob rau hauv cov tub ntxhais, txhim kho cov qauv kev ntseeg siab thiab txo qhov kev pheej hmoo ntawm qhov kub thiab txias.
2.2 Cua txias
Ua rau kev lag luam thiab kev lag luam siv, qhov no 1000 kVA Dyn1 transformer txais cov ntawv ci -mob LV coils thiab ntawv- insulated tooj liab hlau HV coils. Cov qauv kev ua kom zoo ua kom muaj kev ruaj ntseg rwb thaiv tsev, tsis tshua muaj suab nrov, thiab txhim khu kev ruaj ntseg nyob rau hauv 24 kV cov tswv yim thiab cov khoom sib txawv.
2.3 Tank
Transformer tank tiv thaiv cov khoom siv sab hauv los ntawm kev sib tsoo, kev vibration, thiab lwm yam quab yuam. Nws cov qauv steel reinforced ua kom ntseeg tau tias thaum thauj thiab teeb tsa, cov khoom tseem ceeb tseem muaj kev tiv thaiv zoo thiab nyob ruaj ntseg.
2.4 Kev sib dhos zaum kawg
Scotech equips txhua transformer nrog sab hauv Bay -O-Net fuses nyob rau hauv series nrog tam sim no - txwv fuses, loj npaum li cas rau kev tiv thaiv zoo. Peb muab MOV lub luj tshib- hom surge arresters uas ua tau raws li IEEE 386, ua kom muaj kev nyab xeeb ua haujlwm nyob rau hauv cov xwm txheej surge.
