"Lightning Corridor" transform the lightning absorption line high -altitude rack, the power supply is more guaranteed

The Yangtze River Daily Da Wuhan Client September 11 (Reporter Liang Shuang Correspondent Xiong Yin Di) At 9 am on September 11, in Xingcheng Avenue, Wuhan Economic Development Zone, 43 power supply operators were set up about 3 kilometers long in the partition The 10 kV wires are overhead lightning protection lines. This distribution network lightning protection line reconstruction project is an important measure for State Grid Wuhan Power Supply Company to improve regional power supply reliability, which will provide strong power supply guarantee for the automotive industry of Wuhan Economic Development Zone.

The Wuhan Economic Development Zone is located in the southwest of Wuhan. It is located on the east side of the Jianghan Plain, with a flat and open terrain, and some areas are at the "Thunderbolt Corridor". Due to the randomness and concentration of lightning strikes, lightning harm has become one of the main reasons that affect users' safety and reliable power consumption. In order to enhance the thunder resistance resistance of the power distribution line, the State Grid Wuhan Power Supply Company began to pilot the use of overhead lightning mocking lines in the high -incidence area of ​​lightning strike lines.

"Although the 10 kV matching network has a good insulation performance and can reduce the effects of the failure caused by external reasons, it may form a metal short -circuit channel in the insulatory root in the lightning strike. The insulating wire should still seek lightning protection to minimize the impact of lightning strike lines. "Said Zhong Yunjun, a power grid construction class of power supply company power supply company in Wuhan Economic Development Zone.

At present, the company's planned distribution network lightning protection line reconstruction project involves 27 lines of 10 kV lines in the Wuhan Economic Development Zone, covering all the empty and thunder areas of the empty lines outside the yarn area and the dense The entire branch line of the area will be about 160 kilometers of the newly -built airlighted lightning line. It is expected that after the implementation, it will greatly alleviate the lightning and faults of lightning strikes and faults in the lightning weather in Wuhan Economic Development Zone.

It is reported that after the peak summer, the State Grid Wuhan Power Supply Company in an orderly manner launched the power grid construction conference, focusing on optimizing the structure of the grid grid of the area in the area, vigorously promoting power -based operations, combined with power distribution automation technology, steadily improved power supply reliability and the level of power grid operation and maintenance level Essence
