打雷时能不能用电脑

Answer 1

Thunder can use computer 雷雨天气使用电脑应注意： Thunderstorm weather should pay attention to using computer: 1. 在调制解调器、网卡、交换机、集线器等设备的线路接入处安装一个防雷器。 In 1, switches, hubs, LAN modem equipment line access to install a lightning protection device. 2. 如果你的电子电工技术掌握得不错，可以自己采购TVS管制作一个简单的防雷器，这是最经济的。 2 if you have a good grasp of electrical and electronic technology, can buy TVS tube to produce a simple lightning arrester, which is the most economical. 3. 如果你使用了UPS作为电脑不间断电源，建议你在UPS之前加装电源避雷器对UPS予以保护。 3if you are using UPS as computer uninterruptible power supply, suggest you in the UPS before installing power lightning arrester on UPS protected. 4. 使用板载集成网卡上网的用户，在以上措施没有保证的前提下，最好购置一块PCI网卡，即使遭到雷击，损失也只是一块网卡而已。 4using the onboard integrated net calorie to get on the Internet users, in the above measures are not guaranteed under the premise, the best buy a PCI card, even if the lightning, loss is just a piece of card. 5. 普通插座的接地端要接地，地线的好坏不但直接影响着电源防雷器的效能而且还影响到信号防雷器的效能。 5of the common socket ground terminal to ground, ground not only directly affects the power lightning protection device efficiency but also affects the performance of signal lightning protection device. 6. 最安全的方法当然是用完电脑后拔掉网线和电源线，防止雷击或其他意外强大电流入侵。 6the safest course is run out of computer and unplug cable and power line, from lightning or other unexpected strong current invasion. ■案例The case一天深夜，笔者所在公司的电脑不幸被雷击损坏了好几台，电信公司的光电转换器以及交换机、集线器等设备都受到不同程度的损坏。经过近两天时间的检查发现了一个规律，这些电脑均为板载的集成网卡。例如七喜品牌电脑均为主板、CPU损坏，清华同方品牌电脑主板、显卡（AGP）损坏，一部分兼容机由于采用了PCI网卡，只是网卡损坏。 A day of late night, the author is in a company 's computer was killed by lightning damage to several stations, telecommunications company photoelectric converter and switches, hubs and other equipment are subject to different degrees of damage. After nearly two days of examination revealed a rule, these computer are on board the integrated net calorie. For example, Qixi brand computer motherboard, CPU are damaged, Tsinghua Tongfang brand computer motherboards, graphics cards ( AGP ) damage, a partially compatible machine adopts a PCI card, is a card damage. 打雷的时候用电脑肯定有伤害，因为打雷的时候雷电产生高压电，会随着电线倒体传送到用户的电器，这时电器如果在使用状态，随着雷电产生高压电将击穿电器设备。 Thunder when using computer must have hurt, because when thunder lightning to produce high voltage electricity, with the wire down body is transmitted to the user when the electrical appliances, if in use, as the thunder to produce high voltage electricity will breakdown electrical equipment. 强大的雷的电压会导致半导体集成电路被瞬间击穿，失去了原有的极性，所以，集成电路就损坏了，电脑是由大量的集成电路组成的，集成电路都坏了，电脑也就坏了。 Powerful lightning voltage will cause the semiconductor integrated circuit and instantaneous breakdown, lost the original polarity, so, the integrated circuit is damaged, the computer is composed of a large number of integrated circuit, the integrated circuit is broken, the computer will be ruined. 还有就是雷的电压很高，瞬间高压放电会导致空气中的氮气被击穿并燃烧，是放出大量的热，也会把电脑烧毁。 There is a thunder voltage is high, the instant high voltage discharge will lead to the breakdown of nitrogen from the air and combustion, is giving off a lot of heat, also will make computer burned. 再有，雷电的类型属于静电，了解电路的都知道，静电是集成电路的第一大杀手。
