            摘要:
            隨著大長度大截面的電力電纜在隧道的普及,電纜支架因渦流損耗造成的線損、以及發 熱産生溫升形變等問題也日益嚴重。文中采用有限元數值計算方法,以110 kV單相電纜及其鋼 支架爲研究對象,進行了電磁場—流場—溫度場耦合計算。將電磁場計算得到的渦流損耗作爲 溫度場計算的熱源載荷,同時考慮空氣自然對流的散熱方式,從而計算出電纜支架的溫度分布 。最後進行電纜支架溫升實驗,將仿真得到數據和實驗數據進行對比,驗證電纜支架溫升計算 的准確性和有效性。
            Abstract:
            The application of large-length and large-section power cable in cable tunnel leads to the serious line loss caused by eddy current in cable support and the thermal deformation of cable support. Taking 110 kV single-phase cable and its cable support as research objects and adopting the finite element numerical calculation method to calculate its electromagnetic-fluid-thermal coupling field. The eddy current loss calculated by the electromagnetic field is taken as the heat source load in fluid-thermal field, and the heat dissipation mode of the natural convection of the air is considered, thereby calculating the temperature distribution of the cable support. Finally, temperature rise experiment of cable support is conducted,and the simulation data are compared with the experimental one to verify the accuracy and effectiveness of the temperature rise calculation of cable support.
