摘　　要：目前,接触网几何参数测量仪的检定方式存在溯源链过长、误差源较多、检定效率较低等问题。本文针对接触线高度值和拉出值,研制一种检定装置,并通过构建新的溯源链,解决其需在特定空间下的检定问题(实验室净高度不小于6.5m)。试验表明:该装置不仅结构简单,而且提高了检定效率。At present,there are some problems in the verification method of catenary geometric parameter measuring instrument,such as too long tracing chain,too many error sources and low verification efficiency.In this paper,a calibration device is developed for the height value of the contact line and the pull value,and a new traceability chain is constructed to solve the calibration problem in a specific space(the net laboratory height is not less than 6.5m).The test shows that the device is not only simple in structure,but also improves the verification efficiency.
