电感镇流器绕组在灯具热试验中温度的不确定度评定

Evaluation on the Uncertainty of Temperature of Inductive Ballast Winding in Luminairs Heat-testing

介绍灯具在正常工作条件热试验中测量电感镇流器绕组温度的试验过程,使用带电电阻测试仪测得绕组电阻值和玻璃水银温度计测得环境温度值,计算出试验结束时安装在灯具内的电感镇流器绕组的温度值,然后对温度值进行不确定度的评估,最后对试验结果进行符合标准要求的判定。

This article introduces the test processes of measuring inductive ballast winding temperature in the normal operating condition. We use the electrified resistance testing device to measure the resistance and a mercury-in-glass thermometer to measure the ambient temperature when the test starts. The temperatures of inductive ballast winding fixed in the tuminaire and the uncertainty of temperature are calculated, also whether the test result coincides with the standard request or not is evaluated.
