摘要
IE级阀门电动装置是核电厂重要的安全设备,与核安全密切相关,如电动装置额定电流值错误,会造成上游保护配置与实际运行电流不匹配,存在阀门误动作风险。阀门电动装置电机属于短时工作制电机,不同于长时工作制的电机,对于额定电流大家有异议也没有相关的标准明确规定选择合适的电流作为额定电流。本文通过对电动装置的特性进行分析,确定合适的额定电流值选择方式,现场根据该方法对电动装置电流值进行校核,为后续核电厂电动装置额定电流值确定提供重要的参考。
The IE-level valve electric actuator is an important safety equipment in nuclear power plants,which is closely related to nuclear safety.If the rated current value of the electric actuator is incorrect,it will lead to the mismatch between the upstream protection configuration and the actual operating current,posing a risk of valve malfunction.The motor of the valve electric actuator belongs to the short-time working system,which is different from the motor of the long-time working system.There are disputes about the rated current,and there are no relevant standards that clearly specify the appropriate current as the rated current.This article analyzes the characteristics of the electric actuator to determine the appropriate selection method for the rated current value.The electric actuator's current value is checked based on this method,providing important references for determining the rated current value of the electric actuator in subsequent nuclear power plants.
