接触网几何参数测量仪检定台架检定装置测量结果不确定度评定

Evaluation of Measurement Results Uncertainty of Verification Device of Verification Bench for Catenary Geometric Parameter Measuring Instrument

为了保障接触网几何参数测量仪检定台架量值的准确、可靠,建立检定台架检定装置。阐述计量标准测量方法及所用器具。通过测量和计算,依据JJG(铁道)210—2020《接触网几何参数测量仪检定台架》和JJF 1059.1—2012《测量不确定度评定与表示》,分别评定Ⅰ型检定台架模拟接触线高度复现值、接触线拉出值复现值和支柱侧面限界复现值的测量结果不确定度,以保障接触网供电设备的使用安全。

In order to ensure the accuracy and reliability of the verification bench value of catenary geometric pa⁃rameter measuring instrument,the verification device of verification bench is established.This paper explains the measurement standards,methods and instruments used.Through measurement and calculation,according to JJG(railway)210-2020 Verification bench for catenary geometric parameter measuring instrument and JJF 1059.1-2012 Evaluation and expression of measurement uncertainty,the uncertainty of measurement results of simulated con⁃tact line height reproduction value,contact line pull-out value reproduction value and pillar side gauge reproduction value of type I verification bench are evaluated respectively,so as to ensure the use safety of catenary power supply equipment.
