There are many wineries in China, all of which have wine can areas. There are several independent wine cans in the wine can area, which are combined to form a large and small wine can group. Wine is a flammable and explosive liquid, so manufacturers often take very detailed measures to prevent the fire and explosion of wine cans, but the lightning protection of wine cans is often ignored, or the lightning protection measures of wine cans are not taken according to professional lightning protection technology. This paper will illustrate how to protect wine cans from direct lightning through examples. In a word, it is how to design a lightning rod to protect wine cans from lightning.

1. How does lightning strike cause a fire accident?

Lightning strike is always accompanied by fire light, and the objects after lightning strike are usually burnt, because when lightning strikes the building directly, the strong lightning current makes the water in the building vaporize and expand when heated, thus generating huge mechanical force. It may generate tens of thousands of volts or even hundreds of thousands of volts in a few microseconds, produce spark discharge, and convert it into huge heat and mechanical energy, which directly damages buildings and equipment, leads to building burning or explosion, and thus causes fire or personal injury.

An example of a domestic wine tank caught fire after being struck by lightning is: On August 24th, 20 10, an alcohol storage tank was struck by lightning and exploded in the factory area of Yida Liquor Co., Ltd., Huancheng West Road, Ganyu County, Lianyungang City, and then four alcohol storage tanks and 1 alcohol tanker nearby were ignited. Fortunately, the accident did not cause any casualties. 20 12 On August 6th 15: 35, the alcohol tank of an alcohol company in Yang Qing Town, Suixi County, Zhanjiang City was struck by lightning, which caused a fire.

Second, the use of lightning rod

The modern lightning rod was invented by Franklin in 1749. The application of lightning rod has been derived from various forms so far, but its principle remains unchanged. Lightning rod realizes lightning protection through two processes: receiving lightning and releasing current. When Lei Yun discharge approaches the ground, it will distort the ground electric field. A space where local electric field is concentrated is formed at the top of the lightning rod, thus affecting the development direction of lightning pilot discharge, guiding lightning to discharge to the lightning rod, and then introducing lightning current into the earth through grounding downlead and grounding device to protect the protected object from lightning strike.
