摘　　要：为了方便有源零磁通电流传感器的现场使用,研制了一种零磁通电流传感器适配装置,可作为电流传感器的配套产品,其内部集成的具有多种供电模式的电源模块可为现有的大部分主流传感器提供高稳定、低纹波的工作电源。采用电池供电可有效降低电流传感器的零点输出电流;同时通过专用的接口引出传感器的二次电流,并进行I-V变换、数字化等后续处理,在便于测量应用的同时,更拓展了电流传感器的有效测量范围。In order to facilitate the field application of active zero-flux current sensors,an adaptive device for zero-flux current sensors is developed.It can be used as an accessory product of current sensor.Its internal integrated power module with a variety of power supply modes can provide high stability and low ripple power for most of the existing mainstream sensors,and can effectively reduce the zero output of current sensor when using battery power supply.It can lead out the secondary current of the sensor through a special interface.The secondary current is subjected to I-V transformation,digitization and other subsequent processing.It is not only convenient for measurement application,but also expands the effective measurement range of the current sensor.
