Abstract

Abstract: 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 th 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.

Key words: High-voltage power supply, Crowbar, Klystron

摘要： 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。
