| Abstract |
In this study, vibration characteristics in according to the load type of cast resin transformer using vibration measurement device were compared. Measurement conditions are the same installation and operation of the three-phase cast resin transformer. If the load increases in transformer using the rotating machinery, the frequency is growing. In the transformer using the lighting and heating loads, it’s detected the 55 [㎛/s] in or outside and 120 [㎛/s] or more at 60[㎐], the 30 [㎛/s] in or outside at 120[㎐], and the 70 [㎛/s] in or outside at 420[㎐]. When increases the loads, it"s appeared the 60 [㎛/s] or less at 450[Hz] or more in rotating machinery, but the velocity of lighting and lighting loads are appeared from 5[㎛/s] to 115[㎛/s] inside the 420[㎐] in the same load condition of 20[%]. Through this study, it"s verified that there are differences the internal vibration in according to the type of load in cast resin transformer. |
