Protecting method of intelligent circuit breaker closing coil protector

Provided is a protecting method of an intelligent circuit breaker closing coil protector. The method is characterized in that a Hall voltage sensor is used by the intelligent circuit breaker closing coil protector for collecting the voltage signal of the switch-on moment of a circuit breaker loop; by conducting data analysis and processing on the signal, corresponding data is displayed by the intelligent circuit breaker closing coil protector; the intelligent circuit breaker closing coil protector judges whether the control voltage quality of the switch-on moment is qualified or not, which is used as the foundation of protecting movements of the intelligent circuit breaker closing coil protector, and defects in the prior art are overcome. 种智能断路器合闸线圈保护装置的保护方法，其特征在于：智能断路器合闸线圈保护装置使用霍尔电压传感器采集断路器回路合闸瞬间的电压信号，通过对该信号进行数据分析处理，相应的数据通过智能断路器合闸线圈保护装置显示，智能断路器合闸线圈保护装置判断合闸时的控制电压质量是否合格，以此作为智能断路器合闸线圈保护装置保护动作的依据，以克服现有技术的不足。
