【摘要】:高压高阻箱是常见的用于检测绝缘电阻表和高阻计的计量标准器。如何实现其数字化智能检定有着重要意义。本文提出了一种高压高阻箱检定装置用于解决该问题。其原理是使用标准电阻器标定装置内附电阻,通过数字表对被测高阻箱进行测量,利用分压原理计算得到被测高阻箱阻值。文中建立了测量数学模型,对影响测量结果不确定度的各来源进行分析,评定了A类和B类标准不确定度,给出了测量结果的合成标准不确定度和扩展不确定度。同时对高压高阻检定装置的测量结果进行了验证。
[Abstract]:High-voltage high-resistance box is a common gauge for measuring insulation resistance meters and high-resistance meters. How to realize the digital intelligent verification is of great significance. In this paper, a high-voltage and high-resistance box verification device is proposed to solve this problem. The principle is to use the standard resistor to calibrate the inner resistance of the device, to measure the height resistance box measured by digital meter, and to calculate the resistance value of the height resistance box measured by the principle of partial voltage. In this paper, a mathematical model of measurement is established, and the sources of uncertainty affecting the uncertainty of measurement results are analyzed. The uncertainty of class A and class B standards is evaluated, and the synthetic standard uncertainty and extended uncertainty of measurement results are given. At the same time, the measurement results of high voltage and high resistance calibration device are verified.
