一般资料上都介绍,雷雨天最好不要上网,因为雷雨天产生的感应电压会顺着电话线窜入计算机内,由于MODEM是一种精度高、集成度高,可靠性高的电子设备,尤其是集成电路的过载能力比较差,容易造成MODEM损坏,严重的会造成机内其他硬件损坏。对于内置式MODEM其情况更严重。为了避免出现这种现象,我们可以加装一个防雷击的简单部件来保护MO- General information on the introduction, thunder and rainy days is best not to Internet, because the thunderstorm induced voltage generated along the phone line into the computer, as MODEM is a high precision, high integration and high reliability of electronic equipment, in particular Is the integrated circuit overload is relatively poor, likely to cause MODEM damage, serious will cause other hardware damage within the machine. The situation is more serious with the built-in MODEM. In order to avoid this phenomenon, we can install a lightning-proof simple parts to protect the MO-
