实验热虹吸套管建造和测试。热虹吸管由纸树脂套管的中空导体制成，水作为传热流体。试验表明，该套管在临界电流下温度分布均匀，最热点温度接近水的沸点。这种热虹吸套管的载流量比无热虹吸套管的载流量提高了50%。本文提出了热虹吸套管在额定值以上运行时临界电流和最热点温度的简单计算公式。
An experimental thermal siphon bushing was constructed and tested. The thermal siphon was made from the hollow conductor of a paper-resin bushing with water as heat transport fluid. The test shows that this bushing has almost uniform temperature distribution under its critical current and the temperature of its hottest spot is close to the boiling temperature of water. The current carrying capacity of this thermal siphon bushing is 50% more than that of the same bushing without thermal siphon. Simple formulas are proposed to determine the critical current of a thermal siphon bushing and estimate the temperature of the hottest spot if the bushing with thermal siphon is operated above the nameplate rating.
