摘要
本文给出了一种适用于高温气冷反应堆装置的由用水冷却的不锈钢电极、熔铸云母绝缘体和氟橡胶多层密封组合成的引电密封结构。这种结构的试验装置经历了５００ｈ以上的冷态加压试验，多于２９００ｈ的连续工况（１００℃，４．０ＭＰａ氦气）考验和分别２０次以上的压力循环和温度循环试验。在所有工况下，引电密封结构的氦泄漏率都小于５．２×１０－５Ｐａ·ｍ３／ｓ。电极和它所穿过的壳体间的绝缘阻抗大于１００ＭΩ。
A high current electrical Penetration assembly for the pressurized helium electrical heater and its test apparatus were designed and tested.The assembly was undergone the pressure cycle,temperature cycle and soak test for a period of more than 500h and 2900h.The temperature and pressure condition of test was 100℃ and 4.0MPa respectively.The leak rate was less than 5.2×10-5Pa. m3/s and the isolating resistance was larger than 100MΩ.
