The southern United States ushered in the biggest snowfall in a decade. Why does snowfall lead to power failure?

Snowfall leads to power failure because a lot of snow adheres to the wires, which makes the wires bear too much pressure and easily crush them.

202 1 1 10 A rare snowstorm swept across the southern part of the United States and ushered in snowstorm weather. The precipitation in some serious areas is as high as 22 cm. 1 During the two days of 202 1 and1in October, the precipitation in Waco, Texas reached 1 1 cm, breaking the single-day snowfall record set by 1973. According to the local weather forecast, the snowstorm will last for a long time and move to the southeast of the United States.

1. Heavy snowfall in the United States Because the southern part of the United States rarely experiences such terrible heavy snowfall, local residents have no experience in the face of heavy snow. The phenomenon of road icing has brought great inconvenience to residents and great difficulties to local traffic conditions. Relevant local authorities have reminded local residents, hoping that everyone will try to avoid unnecessary travel. In addition, this rare snowfall also caused a large-scale power outage in the southern United States. By the morning of 202 1, 1, 1 1, the power grids in many areas of Texas and Louisiana were down. According to the current situation, it is estimated that more than150,000 American citizens will be affected by power supply. Meanwhile, due to the bad weather, the governments in the affected areas and the COVID-19 Testing Center have to suspend their work.

Second, why does snow lead to power failure? Power outages caused by snow are very common not only in the United States but also in China. There are two main reasons for power failure during snowfall. First, a large amount of ice and snow attached to the wire will bring great pressure to the wire, resulting in the wire being crushed. Secondly, when the weather improves, the sewage left by the melting of ice and snow is easy to cause pollution flashover of power grid protection devices. In this case, the protection line equipment will trip, which is what we often call power failure. There are many statements that are also credible. Many areas rely on coal to generate electricity. Bad weather makes it difficult to transport coal, and thermal power plants can't generate electricity. Winter is a dry season, so the number of people who use water and electricity will decrease accordingly. When the weather is cold, the electricity consumption of residents will increase sharply, which will lead to the shortage of electricity consumption, which is also very common in summer.

Although the 2 1 century ushered in a peaceful era, people's living standards and consumption levels are constantly improving. Most people rely on wind and hydropower to generate electricity, which will not consume too much resources, but we should save electricity and water.
