小功率电动机电气强度试验的研究

The Researches on Electric Strength Test of Small Power Motors

强制性认证产品目录中的小功率电动机广泛应用于各种日用电器中,按照国家规定,它必须符合相关的国家标准才能保障广大消费者的人身安全。电气强度试验是小功率电动机型式试验中的一个重要项目,它是用来检验小功率电动机的绝缘强度是否合格的一个重要手段。本文从国家标准GB/T 12350-2009和GB/T 14711-2013中的相关规定出发,对电气强度的试验方法和判定依据进行了研究,同时也结合相关的实际测试情况提出了一些问题和建议。

The small power motors in the compulsory certification product catalog are widely used in all kinds of daily electrical appliances.According to the national regulations,it must meet the relevant national standards in order to protect the personal safety of consumers.Electrical strength test is an important item in the type test of small power motors.It is an important means to check whether the insulation strength of small power motors is qualified.Based on the relevant provisions of national standards GB/T 12350-2009 and GB/T 14711-2013,this paper studies the test method and judgment basis of electrical strength,and puts forward some problems and suggestions combined with the actual test situation.
