为了提高真空绝缘隔离开关的额定电流，将铜-水热虹吸管嵌入到电气套管中，以显著提高套管的有效导热系数和降低套管的热点温度。通过实验研究了热虹吸套管导体在不同热负荷和填充率下的温度分布。为了估算不同尺寸、不同工质和不同填充率的热虹吸套管的性能，建立了集总热电容器热网络模型。该模型反映了热虹吸套管的厚壁和焦耳热源分布等特性。该模型成功地预测了真空绝缘隔离开关热虹吸套管原型的有效导热系数和热点温度。由于热虹吸套管的紧凑设计，它们可以在广泛的电力设备中实施，例如真空开关设备，隔离开关，等离子体室和高功率物理实验。
In order to improve the electric current rating of a vacuum-insulated disconnect switch, a copper-water thermosyphon has been embedded into an electrical bushing to achieve significantly higher effective thermal conductivity and lower hotspot temperatures of the bushing. The temperature profiles of a thermosyphon bushing conductor under different heat loads and filling ratios have been characterized by experiments. For the purpose of estimating the performances of any thermosyphon bushing with various dimensions, working fluids and filling ratios, a thermal network model with lumped thermal capacitors has been established. Characteristic features of thermosyphon bushings like the thick pipe walls and the distributed Joule heat sources are represented in the model. This model successfully predicted the effective thermal conductivity and hotspot temperatures of a thermosyphon bushing prototype designed for a vacuum-insulated disconnect switch. Because of the compact designs of thermosyphon bushings, they can be implemented in a wide range of power equipment, such as vacuum switchgear, disconnect switches, plasma chambers, and high-power physics experiments.
