　　 阻燃性能良好，好的产品面板通常用手很难直接取下，必须借助一定的工具，而一般的非主流中低档产品则很容易用手取下面盖，造成家居和公共场所的不雅，结构:目前开关结构主要有跷板式和摆动式两种，跷板式开关声音雄厚。

　　热继电器中通过的过载电流与热继电器触点的动作时间关系，称为热继电器的保护特性，如图1中曲线2所示。考虑各种误差的影响，电动机的过载特性和继电器的保护特性都不是一条曲线，而是一条带子。显而易见，误差越大，带子越宽；误差越少，带子越窄。

　　再有可能是空开本身的质量问题，建议你换一个容量大的空气开关，再就是一定要将接地插头插上，不要掰到一边去。1、空气开关的过电流脱扣线圈，串联在主回路中。当通过较大的电流时，脱扣线圈的衔铁就会被磁场吸引，由于电流还没有达到跳闸的强度，所以衔铁会在磁场及弹簧的作用下，来回振动、发出明显的噪音（电流声）。

韩国AD50-25F 25A 1"广泛应用　　这样就从根本上消除了表面漏电流的影响，特别应该注意的是测量电缆线芯和外表之间的绝缘电阻时，一定要接好屏蔽端钮“G”，因为当空气湿度大或电缆绝缘表面又不干净时，其表面的漏电流将很大，为防止被测物因漏电而对其内部绝缘测量所造成的影响，一般在电缆外表加一个金属屏蔽环，与兆欧表的“G”端相连。　　实验证明，对于一般导体其随温度的变化可近似表示为：式中ρ和ρ0分别是摄氏温度为t和0时的电阻率，α称为温度系数，取决于材料的种类。电阻的计算：当导体的截面S或电阻率ρ不均匀时，则其电阻计算式为：式中dl为沿电流方向的长度元，计算时要注意电流是沿什麽方向流过导体的，S为垂直于电流方向的面积。
　　其它的三组道理也一样，接在2和3上的话60秒电机启动。需要说明的是时间继电器分为通电延时和断电延时，如果你买的是通电延时的，接在2和3，时间继电器通电后电机60秒才启动，如果你买的是断电延时的刚好相反，电机60秒才会断开电源停止运行，现在才说主要怕有些人搞乱了。
