| 摘 要： | 分析了由于使用环境造成的一种平板电视机不安全因素。通常使用电视机就需要连接建筑配电系统和CATV信号系统,在这样的使用环境中很难保证不同系统之间的等电位接地,进而导致电视机的不安全。文中阐明了不同系统接地影响电视机使用安全问题的处理措施和思路。

| Abstract: | An unsafe factor caused by using circumstances for flat TV sets is analyzed by this article.Generally TV sets have to be connected to power distribution system and linked with CATV system at the same time while they operating.To keep the two systems earthed equipotential is difficult,the situation result in TV sets unsafe on occasion.Some steps for the safety problem since different systems operated have been shown as well. |
