摘要
该文提出了一种基于FPGA的高压断路器分合闸线圈电流及分合闸时间检测系统的设计方案。该方案以FPGA为控制核心,通过AD芯片对断路器分(合)闸线圈电流信号的进行采集,并通过FIR滤波器对采集到波形进行数据处理,实现高压断路器线圈电流-时间特性检测方法。实验结果证明,该方案可实现断路器合(分)闸线圈电流和时间特性的检测,为及时发现故障提供重要依据。
This paper presents a design scheme of detecting current and time of opening and closing coil of high voltage circuit breaker based on FPGA.The scheme takes FPGA as the control core,collects the current signal of the circuit breaker’s opening(closing)gate coil through AD chip,and processes the data of the collected waveform through FIR filter,so as to realize the current-time characteristic detection method of the high-voltage circuit breaker coil.The experimental results show that the scheme can detect the current and time characteristics of the circuit breaker closing(splitting)gate coil,and provide important parameters for timely fault detection.
