摘要
为了保障铁路轨道信号在线测量仪测得的ZPW-2000A轨道电路补偿电容容值准确、可靠,依据JJG(铁道)702-2021《铁路轨道信号在线测量仪检定规程》,利用XHBQ-Ⅰ型轨道信号测试设备综合校验仪,检定铁路轨道信号在线测量仪.介绍检定方案,评定补偿电容检定结果不确定度,并进行验证.结果表明,检定方案满足量值传递要求,能保证铁路轨道信号在线测量仪测量的电容结果准确、可靠.
Abstract
In order to ensure the accuracy and reliability of the capacitance value of the compensation capacitance of ZPW-2000 A track circuit measured by on-line measuring instrument of railway track signal,according to the JJG(Railway)702-2021 Verification regulations of on-line measuring instrument of railway track signal,the XHBQ-I comprehensive verification instrument for testing equipment of railway track signal is used to verify on-line measur-ing instrument of railway track signal.The paper introduces verifying scheme,and the uncertainty of the capacitance verification results of the compensation capacitance is evaluated and verified.The results show that the verifying scheme meets the requirements of value transmission and can ensure the accuracy and reliability of the capacitance values measured by on-line measuring instrument of railway track signal.
