Design and realization of the protection system of high-voltage power supply of the EAST low hybrid current drive

介绍了EAST低杂波高压电源保护系统的设计和实现。在EAST装置低杂波电源保护系统中,以主回路过电流﹑管体过电流﹑高压源主回路过电流﹑高压源主回路过电压为主要参数来保护系统正常工作的。在主回路过电流﹑管体过电流时通过撬棒来转移故障电流来保护速调管。

Design and realization of the protection system of high-voltage power supply of the EAST low hybrid current drive are described, in which the over-current in main circuit and tube body, and the over-current and over-voltage in the high-voltage circuit are considered as the basic protection parameters for the system. Consequently, the crowbar will protect the klystron by transferring the fault current when the over-current takes place in the main circuit and tube body.
