核电厂KIR系统专用信号转换装置为KIR系统关键部件，属于一种特殊的电荷放大器。现场使用设备故障率高，常用的电荷放大器不能满足KIR系统特定的参数、接口、质保、结构等技术要求。本文针对这一问题，结合KIR系统特定的技术要求，对信号转换装置的电气、结构等特点以及功能需求进行了分析，设计了核电厂KIR系统专用信号转换装置，并进行了仿真验证和现场验证。结果表明，该设计满足了KIR系统的功能需求。%Nuclear power plant systems KIR-specific signal conversion device as key components of KIR the system, it is a special charge amplifier. Equipment failure rate of use on site, common charge amplifier can not meet the technical requirements of specific KIR system parameters, interfaces, quality and structure. Aiming at this problem, combined with KIR system-specific technical requirements, electrical, structural and functional characteristics of the demand signal conversion device performs the analysis and design of the nuclear power plant KIR system dedicated signal conversion apparatus, and simulation verification and on-site verification. The results show that the design meets the functional requirements KIR system.
