雷雨季节即将来临,认真做好工厂、企业、仓库等方面的防雷击工作,对保障安全生产和物资储存的安全极为重要。雷电是一种常见的自然现象。雷电电压高,电流大,闪电内部的温度约高达2万度以上,为太阳表面温度的五倍。在放电时能产生热效应和机械效应,这两种物理效应具有极大的 The thunderstorm season is approaching and serious efforts will be made to prevent lightning strikes in factories, enterprises, and warehouses. It is extremely important to ensure the safety of production safety and material storage. Lightning is a common natural phenomenon. The lightning voltage is high and the current is large. The temperature inside the lightning is about 20,000 degrees or more, which is five times the surface temperature of the sun. Thermal effects and mechanical effects can occur during discharge. These two physical effects have great
