Abstract

Switching network unit (SNU) is one of the important systems in the power supply system of fusion devices, which excites and establishes plasma current. A mechanical switch has been designed for SNU backup protection, which can short-circuit other components in case of SNU failure to prevent further deterioration of the situation. An optimized contact system is used in this switch to improve the maintainability of the contacts. A detailed structural design was carried out for the switch, and the final prototype test results verified that it meets the relevant design requirements. This backup protection scheme can provide a certain reference for the engineering design and reliable operation of SNU.

用于融合设备中交换网络单元后备保护的机械开关的分析、设计和测试

开关网络单元（SNU）是聚变装置供电系统中的重要系统之一，用于激发和建立等离子电流。我们设计了一种机械开关，用于 SNU 的后备保护，当 SNU 出现故障时，它可以短路其他组件，防止情况进一步恶化。该开关采用了优化的触点系统，以提高触点的可维护性。我们对开关进行了详细的结构设计，最终的原型测试结果验证了它符合相关的设计要求。该备用保护方案可为 SNU 的工程设计和可靠运行提供一定的参考。
