On February 5, a news of sparks on the roof of a bullet train attracted widespread attention. In this regard, experts pointed out that this is due to the "arcing" phenomenon caused by high voltage between the pantograph and the catenary. Under extreme weather conditions, such as the current rain and snow, the catenary and the pantograph may be insulated by thin ice, and when the voltage is too high, this insulation will be broken down, resulting in electrical sparks.
Recently, many places in China have encountered rain and snow weather, and the railway department is making every effort to prevent low temperature rain and snow freezing disasters to ensure the safe operation of trains. From the night of February 5 to February 7, Hunan, Hubei, northern Jiangxi, central and southern Anhui, southern Jiangsu, central and northern Zhejiang will usher in snowfall again, and Shanghai may also have a short period of snowfall.
However, from February 8, the cold and warm air will weaken sharply at the same time, and the snowfall in the southern region will basically stop. It is expected that on February 9, except for Altay in Xinjiang, most parts of the country will usher in cold and sunny weather. By February 10, the snowfall in Xinjiang will also stop, and most of the country will usher in a beautiful new year without wind, rain and snow.
In the face of complex and volatile weather conditions, we need to pay close attention to meteorological information to ensure our own safety. Passengers are also requested to pay attention to the train transportation conditions in time and arrange their travel plans reasonably. February** Dynamic Incentive Program
