Concentric jacket pipe surrounded the test condenser. steam was generated in the boiler, flowed upward to the inlet of connection pipes, then flowed downward into the condenser tube, the cooling water flowed countercurrently through the annulus. the experiment covered the range of the pressure 1. 0 ~ 3. 0bar, heating power 2. 0 ~ 15. 0kw, steam mass flow rate 0. 001 ~ 0. 004kg / s, air mass flow rate 0. 0 ~ 0. 00163kg / s, and cooling water temperature 20 - 60 ?
在系統壓力為0 . 1 0 . 3mpa ，加熱功率為2 15kw ，蒸汽質量流量為0 . 001 0 . 004kg s ，空氣質量流量為0 . 0 0 . 00163kg s ，二次側冷卻水溫度20 60的范圍內，系統研究了豎直下降管內含有空氣的蒸汽冷凝特性，獲得了不同壓力、不同空氣含量和不同加熱功率下，冷凝段的溫度分佈和局部熱流密度的數據。 -
By close study on the average temperature rise, temperature distribution, and tune constant of the class f resin dry type power transformer ' s high voltage and low voltage winding under self - cooling and wind - cooling mode, we find out the connection between the variation of the load and the items, mentioned above. the results of the experiments can be reference to both thermal design optimization of dry type power transformer and the revision of current standards. meanwhile, we develop the software, which can predict the overload ability of the dry type power transformer
本文對f級樹脂澆注式乾式變壓器的高、低線圈的平均溫升，內部溫度分佈和時間常數在自冷和風冷，兩種冷卻方式下隨負載變化的規律進行了研究，得出了平均溫升、熱點溫升和時間常數隨負載變化的相互關系和有關計算用參數和公式，試驗結果可作為改進乾式電力變壓器的熱設計的依據和對現行標準進行修改的參考。 -
