电气安全测试中空调器电机绕组的正确测量

Accurate Measurement of Air Conditioner Motor Winding in Electrical Safety Testing

GB 4706.32-2012《家用和类似用途电器的安全——热泵、空调器和除湿机的特殊要求》对家用及类似用途的空调器在安全方面作了强制性规定,其中第11章的发热试验是考察空调产品质量安全非常重要的指标,尤其是涉及电机的温度测量和计算繁琐且复杂,因此如何能够准确地对空调器电机绕组进行测量显得尤为重要。本文通过结合空调器安全标准条款要求,针对空调器电机在实际测试中的绕组测量展开对比分析,并总结提出科学精确的测量方法,以达到对整个空调产品的安全合格性更全面更准确地评估。

GB 4706.32-2012 ＂Household and similar electrical appliances- Safety- Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers＂ is the mandatory criterion for air conditioners with household and similar purposes in terms of security, which the heating test of 11th chapter is a very important indicator for evaluating the safety of air conditioning products, particularly the measurement and calculation of fan motor temperature is very complicated, so how to measured the windings of fan motor accurately is very important. In this paper, according to the requirement of air conditioners safety standards, we made a comparison and analysis for the windings measurement of air conditioner motor in the actual test, and put forward the scientific and precise measurement method, to achieve more comprehensive for the safety of the air conditioning products eligibility assessment more accurately.
