二、EMC国际标准概述无线电设备、高频应用设备及数字式设备等产生的电磁干扰波,往往会导致其周围的电气设备发生工作失常等故障,这种现象称为电磁干扰.最近几年以来,由于电气与电子设备不断地进行技术革新.在低频领域,因高次谐波而造成电气设备温度升高发生故障,甚至导致火灾等事故;在高频领域,对电视或者电话等形成噪声干扰的情况正在增多.
Second, the EMC international standards Overview Radio equipment, high-frequency application equipment and digital equipment such as electromagnetic interference waves, often lead to the electrical equipment around its malfunction, such as malfunction, a phenomenon known as electromagnetic interference in recent years , Due to continuous technological innovations in electrical and electronic equipment. In the low frequency area, the temperature of the electrical equipment due to higher harmonics is faulty, leading to accidents such as fire. In the high frequency area, noises are disturbed to the TV or the telephone The situation is on the rise.
