摘要：

通过检测打火短路过程中产生较大的di/dt 和du/dt 来实现高压电源的打火短路保护。在研究了中性束加速电源控制和保护特点的基础上, 设计了诊断中性束加速电源在打火短路过程中的di/dt 和du/dt 的检测电路和相应的保护电路, 实现提前对加速器高压电源打火短路的保护。

Abstract:

The accelerator power supply is protected by detecting the di/dt and du/dt , when the power supply is arcing. The protection characteristics of the DNB power supply system are studied. Based on this, the detection circuit of di/dt and du/dt in the power supply arcing and the corresponding protection circuit are designed.Therefore the protection of the accelerator power supply can be achieved in advance.

Key words: Diagnost ic neutral beam, Accelerator power supply, Detection of di/dt and du/dt , Protection of arcing
