舰船智能化组合式电子互感器研究

Intelligentize Electronic Transducer for Worships

随着舰船电力系统容量的不断增长,舰船额定电流和故障电流都成数量级增长,原有的互感器已逐渐不能满足应用的要求了,通过介绍新型船用电子互感器的一种类型—智能化组合式电子互感器,提出以Rogowski为电流互感元件并简要分析了Rogowski线圈的结构原理和数学模型,电压传感部分和电源部分设计方案,对信号集中处理电路模块作了详细的分析。该互感器集电流、电压、功率方向等电网运行参量的测量于一体,同时提供与继电保护设备以及远程控制计算机的CAN总线通信接口,符合未来舰船智能化监控系统改装的要求。

The rating current and short current are both going up while the warship electric power system increased.Former transducer can not satisfy the demand of the worships anymore.This article introduces a new intelligent electronic transducer for worships.A Rogowski coil and a resistance voltage divider are used as current sensor and voltage sensor respectively in the design;we analyze the parameter and mathematic model of Rogowski coil and the details of signal-disposal particular.The transducer use VT for powe...
