Abstract

The ITER In-Vessel Coils (IVC) are water-cooled coils, composed by a mineral-insulated copper conductor, enclosed in a stainless-steel jacket. The system is installed inside the ITER Vacuum Vessel, and it is fed by high-voltage feedthroughs that provide electrical power and cooling water to the copper conductors. Each coil is cooled individually and has dedicated inlet/outlet stainless-steel pipes in the ex-vessel area. To electrically separate the IVC from the ITER cooling water system, an electrical insulating break is needed.

The IVC Insulating Break (IB) is operated in a radiation environment and at temperatures up to 240 °C. It shall provide electrical insulation up to 2.4 kV and shall withstand cooling water pressure up to 44 bar as well as mechanical and thermal loads related to the ITER IVC operations.

ITER容器内线圈陶瓷绝缘断口的设计与鉴定

热核实验堆容器内线圈（IVC）是水冷线圈，由矿物绝缘铜导体组成，并包裹在不锈钢护套内。该系统安装在热核实验堆真空容器内，由高压馈入装置为铜导体提供电力和冷却水。每个线圈都单独冷却，并在舱外区域装有专用的不锈钢进口/出口管道。IVC 绝缘断路器 (IB) 在辐射环境和高达 240 °C 的温度下运行。IVC 绝缘断路器 (IB) 在辐射环境和高达 240 °C 的温度下运行。它应提供高达 2.4 kV 的电气绝缘，并应承受高达 44 bar 的冷却水压力以及与热核实验堆 IVC 运行相关的机械和热负荷。
