隔爆型电动机表面温度测试分析

Analysis on Surface Temperature Test of Flame-Proof Motor

温度是电动机防爆性能的重要指标之一,由此介绍了国内GB 3836.1和美国UL 674防爆电机表面温度测试的要求和方法,以隔爆型电机表面温度测量为例,介绍了不确定度的来源以及处理方法,对实验结果不确定度进行分析与计算,得出的结论供实验人员参考。

Temperature is one of the important performance indicators of explosion-proof motor. Based on it, this paper introduces the requirements and methods of surface temperature test tor explosion-proof motor specified in domestic GB 3836.1 and American UL 674. Taking the surface temperature test of a flame-proof motor as an example, this paper introduces the sources and handling methods of uncertainty. The uncertainty of the experimental result are an- alyzed and calculated, and the obtained conclusion can provide reierence tor the testers.
