摘要
从电气间隙、爬电距离和固体绝缘三个方面的影响因素和测试步骤,分析音视频产品内部绝缘配合的设计与考核要求;结合符合与不符合设计要求的音视频产品实例,分析绝缘配合的应用;阐明GB 8898-2011对音视频产品内部绝缘配合的相关要求。
From the three influencing factors and test steps of electric clearance, creepage distance and solid insulation, the design and assessment requirements of internal insulation coordination of audio and video products are analyzed. The application of insulation coordination is analyzed in combination with examples of audio and video products that meet and do not meet the design requirements.The related requirements of GB 8898-2011 on internal insulation coordination of audio and video products are clarified.
