中文摘要 | 本文首先敘述台電輸電系統在一變壓器遞昇加壓試驗過程中,引起異常 感應高電壓的經驗,經判定係輸電線路之耦合共振狀況。接著討論此種耦合共振 的基本理論及造成共振的條件。最後舉此實例說明耦合共振的計算,並探討天候 因素及介電常數變化對耦合共振之影響。如何避免耦合共振之發生,亦在本文討 論之。 |
英文摘要 | In this paper, the phenomenon of abnormal highinduced voltage in transmission line during a step-risingenergized test of a transformer was first introduced. Thisphenomenon is caused by coupled resonance. Then, the basictheory and conditions causing coupled resonance in transmission line were discussed. A real instance was cited to illustratethe calculation of coupled resonance. Finally, the influence ofweather and dielectric constant on induced voltage wasdiscussed. The countermeasures for preventing the occurrenceof coupled resonance were also proposed. |
