Abstract

Abstract: The poloidal field (PF) converter belongs to the critical systems of ITER, thus its reliability and availability should maintain a high state through the two decades operation life of ITER. This paper is aiming at improving these two abilities with the RAMI (Reliability, Availability, Maintainability and Inspectability) analysis method. The system functional breakdown is performed at first, then the reliability model is established based on it. The initial reliability and availability of the PF converter is obtained by analysing this model. Finally, by improving the reliability and availability of subsystems, the scheme of the PF converter satisfied the requirements of ITER.

Key words: Poloidal field, Converter, RAMI Analysis, Reliability, Availability

摘要： 极向场(PF)整流器是国际热核聚变实验堆(ITER)关键系统之一，在ITER 20年使用寿命期间，应该具有较高的可靠性和可用性。运用RAMI(可靠性、可用性、可维护性、可检测性)分析的方法，首先对系统进行功能划分，然后在其基础上建立了系统可靠性模型，通过该模型计算得到PF整流器的可靠性和可用性初始值，最后提出改进方案提高了PF整流器的可靠性和可用性，使之满足ITER的需求。
