Recently, Sichuan Zigong continued to have high temperature weather, and the temperature frequently exceeded 40 ° C. On July 11, at the 110 kV Nanhu substation site, the State Grid Zigong power supply company transformer operation and maintenance personnel used 300 large ice cubes to carry out "heatstroke prevention and cooling" to ensure the safety of surrounding residents.

"The temperature of the transformer is as high as 85 ° C. The ice cubes that have just been put in have melted, and the temperature between the main variables is much lower than there is no ice cubes." Wang Jie, a transformer operation and maintenance personnel, said, " Our work task today is to place these 300 pieces of ice cubes in the main transformer, and give the transformer to the "heatstroke prevention and cooling '".

At 3 pm that day, when the hottest day was the hottest day, the person in charge of the on -site work was in order to command more than ten personnel to arrange the ice cubes. It is understood that the 110 kV Nanhu substation is located next to National Highway 348 of the Ziliujing District. It is very important for residents' electricity and commercial electricity for residents in the Nanhu area of ​​Zigong City. It is very important. There are two transformers in Nanhu substation, with a total power supply capacity of 100,000 kV.

With the continuous high temperature and hot weather in Zigong City, the load of electricity has soared, and the Nanhu substation has a different degree of overloading and even overloading. The temperature of the transformer is too high and the power supply safety and reliability are facing severe tests.

At present, in order to ensure the safety of power supply in the main urban area, the State Grid Zigong Power Supply Company has adopted measures to "prevent heatstroke prevention and cooling" of 110 kV Nanhu, Huidong, Xinhua, Begonia and other urban areas to escort the "cool summer".

At present, under the continuous high temperature and hot weather, the heavy load of the power grid is obvious. The State Grid Zigong Power Supply Company has strengthened equipment inspection inspections, increasing the frequency of inspection of important line channels and key substations, and timely discharge of the hidden dangers of equipment discovered. Up to now, 570 hidden dangers of high and low pressure lines have been carried out, and 142 hidden dangers have been eliminated.

The high temperature and sunny climate is still continuing, and the power grid bearing capacity is facing huge challenges. The State Grid Zigong Power Supply Company calls on the whole society to save electricity and scientific electricity, and adjust the air conditioner temperature above 26 ° C. When the heat defects occur, please call the local accident to report the phone call.
