Research on the Wave-recording Device of Short Current in DC Voltage-variation Grid of Ship

介绍了一种录波装置,可用于舰船直流幅压电网短路电流的波形测量和记录。针对直流电网短路电流上升率高、幅值大的特点,重点分析了Rogowski线圈的测量原理,阐述了录波装置的硬件设计和工作流程,并给出了现场测试结果,对基于Rogowski线圈的电流录波装置的应用前景进行了展望。

This paper introduces a wave-recording device,which is used in wave-measurement and recording of short current in DC voltage-variation grid of ship.To account for the high-rate and large-amplitude of the short current in DC voltage-variation grid of ship,measuring principle of rogowski coils is discussed.Then,hardware design and workflow of the wave-recording device have presented in the paper.Field test results of wave-recording device is presented,too.At last,the application expectation of the wave-recording device based on rogowski coil is described in the paper.
