摘要
介绍了核电厂核测量系统基本原理,分析了空间辐射干扰、电源干扰、传输线干扰和电子器件噪声等干扰源对核电厂核测量系统产生的不利影响;研究了核测量系统相关抗电磁干扰策略,总结了抑制核测量系统电磁干扰的多种有效措施;并探讨了核电厂电磁兼容抗扰度试验方法及相关法规。指出了为了满足核电厂核测量系统的抗扰度要求,未来核测量系统将向着低噪声前端电子学设计和全数字化信号处理的方向发展。
The basic principles of nuclear measurement system in nuclear power plants are introduced in this paper. Electromagnetic interference sources such as space radiation interference,power interference,transmission line interference and electronic device noise. are Analyzed. By studying anti-electromagnetic interference strategies of nuclear measurement systems, several effective measures to suppress electromagnetic interference are summarized. And nuclear power plant electromagnetic compatibility test methods and standards are discussed. In order to meet the immunity requirements of the nuclear measurement system in nuclear power plants,nuclear measurement systems will turn toward to low-noise front-end electronics design and all-digital signal processing.
