High temperature "baking" to test their "heaven and earth" protection of thousands of cool personnel | electricity | high temperature

As the hot weather continues, the electricity load is also continuously increasing. In order to ensure the stable supply of electricity in summer, power personnel have stood firm on the front line in high temperatures, "up in the sky" and "down in the ground", guarding the coolness of thousands of households.

Video photographer Ms. Zhang: Around 11 noon, they are at the highway service area. At first, I thought it was a bird, but after zooming in, I realized that the workers were working on the wires. I felt so shocked at the time. We don't even want to stay in the service area because it's really hot outside and it's really exhausting for them.

A video of a power grid employee walking in the air at a height of 100 meters quickly became popular on the internet. The person in the video is the transmission staff of Shenzhen Power Supply Bureau of Southern Power Grid. On that day, after taking safety precautions, they climbed a 100 meter high tower equivalent to 30 floors under the scorching sun and carried out line inspection work on a one kilometer 500 kV transmission line.

Wu Songtao, the team leader of the transmission management office of the Shenzhen Power Supply Bureau of Southern Power Grid, said: Our tower operations are carried out in pairs, with everyone taking care of each other. The ground coordination personnel also use drones to constantly observe everyone's physical condition in the air. Being able to bring coolness to everyone during the peak summer season is also worth our hard work.

In Suzhou, at a 13 meter high railway operation site, 10 workers wearing insulated suits braved the scorching sun and took turns riding bucket trucks for aerial operations. When I came down, my work clothes were already soaked and stuck to my body. Taking advantage of the short rest time, they quickly drank water, washed their faces, and changed their clothes.

Shen Songmin, a non power outage worker at State Grid Suzhou Power Supply Company, said: We have spare ones, please bring them over and replace them with another set. Dry this set in the sun, then wait until the next job is done before switching to another set.

In addition to going to heaven, power workers also need to go to the ground.

The cable duct gallery located 70 meters below the seabed in Xiamen, Fujian has a narrow space and poor ventilation environment, with temperatures approaching 40 ℃ in summer. Local power inspectors wear headlights and intelligent alarm wristbands to overcome unfavorable conditions and conduct inspections on high-voltage cables to ensure power supply safety.

Lin Yunsen, the cable inspection team of State Grid Xiamen Power Supply Company, stated that in this enclosed space, we strictly implement the safety requirements of "ventilation first, testing later, and operation later" to ensure air circulation. Operators always maintain reliable communication with external personnel and pay attention to their own heatstroke prevention measures.

Five shifts ensure stable energy and electricity supply

In recent days, many parts of Shandong have been experiencing high temperatures, and electricity consumption in various regions has gradually increased. There is a group of people who are still standing by the fireplace in high temperatures. Let's follow the reporter into the power generation enterprise and see how the frontline employees there have persevered through sweat.

At 9am, the outdoor temperature in Dongying, Shandong had reached 37 ℃. In the turbine operation floor of this power generation company, the indoor temperature has exceeded 45 ℃. All the heat generated by the combustion of coal-fired boilers is converted into electrical energy through the work done by the steam turbine, which is also the hottest workshop in the entire power plant. To ensure the safe and stable operation of the generator set, daily inspections are essential. Through the temperature measuring gun, it can be seen that the bearing temperature of the power turbine has reached 69 ℃, and the staff's clothes have been soaked in sweat, with bean sized sweat droplets sliding off their faces. As the "heart" of the generator set, the internal temperature of the steam turbine can reach over 600 ℃.

Xu Muyin, a steam turbine inspector at Datang Dongying Power Generation Co., Ltd.: Today, the outdoor temperature is 35-36 ℃. Our factory is currently experiencing higher temperatures, so we are implementing a five shift system. Every 20 to 30 minutes of work, we have to take a break to change shifts, which is about 20 to 30 minutes of rest.

In the scorching summer, in order to effectively carry out safety production and heatstroke prevention and cooling work, the company has optimized work task arrangements, increased rotation shifts, and extended the rest time of frontline employees. At the same time, the prepared heatstroke prevention and cooling items such as watermelons, beverages, and Huoxiang Zhengqi water will be moved to the front line of the factory to minimize the impact of high temperatures on the health of workers.

Yuan Kai, Director of the Power Generation Department of Datang Dongying Power Generation Co., Ltd.: We have also set up a dedicated lounge, which is also air-conditioned 24 hours a day.

The high temperature weather continues, and the demand for electricity in society continues to rise, increasing the pressure on energy and electricity supply. As a major power generator in the northern Shandong region, the enterprise has the world's first "six cylinder six exhaust" million kilowatt coal-fired power generation unit. To cope with high temperatures and ensure the safe operation of the generator set, the frontline team in the factory operates at full capacity 24 hours a day.

Yuan Kai, Director of the Power Generation Department of Datang Dongying Power Generation Co., Ltd.: Currently, both of our units are operating at full capacity, and the daily power generation can meet the electricity demand of the three Dongying Port Economic Development Zones. Increase the number of inspections for important equipment, monitor the temperature of rotating equipment, ensure the safe and stable operation of the unit, and fully guarantee the power supply.

At present, the maximum daily power generation of enterprises can reach 45 million kilowatt hours, effectively ensuring the orderly supply of energy and electricity.

Tips for preventing heatstroke during outdoor work

Working in hot weather has brought great challenges to frontline production personnel. In order to ensure the life, health, and safety of outdoor workers, power personnel from various regions have developed multiple heatstroke prevention and cooling strategies based on the special working environment. Let's take a look together.

In Henan, power workers dynamically adjust their work plans based on daily temperature changes, using methods such as early start of work, extended lunch break, and delayed end of work. When the highest temperature of the day reaches 40 ℃ or above, outdoor operations shall be stopped; At 37 to 40 ℃, the cumulative outdoor work time shall not exceed 6 hours.

In Anhui, heatstroke prevention and cooling items such as mineral water and fruit juice are placed at the work site, and staff can replenish energy and water in a timely manner. In order to provide better rest for employees, a sunshade has been specially built on site, and there is even an air-conditioned lounge.

In Beijing, wiping the skin with alcohol wipes to cool down, taking Rendan pills before starting work, and taking Huoxiang Zhengqi water after completion have all become small tricks for power workers to prevent heatstroke.

Not only are people afraid of heatstroke, but equipment also needs to be cooled down. Under the cover of high temperatures, the temperature inside the substation can reach over 50 degrees Celsius, which is a great test for the electrical workers inspecting inside. In a substation in Jiaxing, the reporter saw that the cooling water cannon was continuously spraying water mist at the equipment, reducing its temperature. In addition, some technological means such as robot inspections and drone inspections are also being incorporated into the work of high-temperature electricity protection.
