摘要:
针对目前传统电力机车用电压互感器存在谐振、在机车过电分相时容易造成过电压等缺陷,提出了一种新的检测方案,有别于传统的电磁感应方式,该方案使用阻容分压,并通过光纤传递数字信号。相对于传统互感器本方案在体积、绝缘、安全、精度方面均有较大优势。试验结果显示该方案性能优良,并可满足机车需求。
Abstract:
For the issue that resonance of traditional voltage transformer used on electric locomotives causeed overvoltage while locomotive passing neutral section, a neu design was presented with resistive-capacitive voltage measurement method replacing existing electromagnetic method and optical fiber transmitting digital signals. The new design showed the advantages such as small size, excellent insulation, operating security and high measuring accuracy. The tests proved that the new design had an excellent performance and could meet the demand of locomotive.
