摘　　要：EAST装置是"九五"国家重大科学工程项目之一,做为世界上第一个全超导托卡马克装置,其纵场和极向场线圈全部由超导磁体组成,进行安全,准确,有效的失超保护是装置安全运行的首要环节。如何在全超导托卡马克装置这样复杂的电磁环境进行失超检测在世界上也无先例可寻。EAST上失超检测系统经过几十轮单饼超导线圈实验及两轮装置正式放电实验后逐步建立和完善起来,并已通过工程验收达到装置实验运行要求。主要介绍了EAST超导装置失超检测系统的基本结构和检测原理,同时还简述失超检测技术的发展并给出了实验结果。East Device is one of national key science technical projects and the first fully Superconducting Tokamak Device in the world.Quench protection is very important issues for the safety operation ofthe Superconducting magnets.There is no precedent in the world on how to carry out quench detection in such complex magnetic circumstance of fully Superconducting Tokamak device.After several commission experiments,quench detection system has been developed and improved which can satisfy predefined requirements and pass acceptance of work now.Basic structure and design principle of the prototype system was involved and also the development process and test results were presented.
