摘　　要：提出了电流-温度传感新方案,它在解决光纤电流互感器性能不稳定问题上有突出的理论优势。文中建立了电流-温度传感的数学模型,分析了暂态、稳态特性,给出了光纤电流互感器实验装置及测量结果。理论分析及实验测试表明,只要技术措施得当,采用本传感方案实现全光纤电流互感器是可行的。For resolving the difficulties on the instability of optical fiber current transformer, a novel current-- temperature sensing scheme is presented. It has the theoretical advantage of eliminating the problem of instability .The mathematical model of the sensing system is established to analyze the steady and transient characteristics. An experimental current transformer is constructed for testing. Theoretical analysis and experimental results show that this scheme is available if appropriate technique are used.
