摘　　要：为快速分析电流互感器发生断线时的二次电流幅值,根据电路的叠加定理,将故障前状态和故障后状态叠加后进行分析,有效地简化了电流互感器二次断线故障的分析工作.该方法有利于及时发现并处理事故,对故障报警装置的设计具有参考价值.In order to solve the problem of secondary disconnection of the current transformers, this study utilized the superposition theorem of electrical circuits and analyzed the circuits with superposition of the state of before and after the glitch to superposition. Using this method can avoid the tedious process of general analysis of current transformer disconnection effectively. This method has advantages in handling of the accident, protecting the installation and making sure the security automatic equipment is in normal operation, which is beneficial to the future improvement of related work.
