CNET News Huang Lei reported at 11:06 on August 23, State Grid Jiangsu Power Company overhaul branch high voltage live class squad leader under the command of Chang Changsong, located in Xuzhou 500 kV Guo Dai 5611 Line 1 tower C phase trumpet side wire drain fever defects were successfully eliminated. This is also the 1000th EHV (500 kV) and above voltage class live work completed since its establishment in 2000.

Continuous steaming over the past few days in Jiangsu in the earth, but also led to the Jiangsu power grid load steadily increased, Jiangsu power grid in a long time in high-load operation, part of the grid equipment is close to the operational limit. In order to ensure the safe and reliable supply of electric power, the provincial inspection and repair company high-voltage live working class of 16 operating personnel even shaft, since June a total of 36 EHV and above charged operations completed.

On August 22, Yan Guangqing, the supervisor of the power transmission overhaul department of the Xuzhou Branch of the provincial maintenance company, found an emergency defect when inspecting the 56,000-line Guo-Dai line of 500-kilovolt - No. 1 tower C phase trumpet lateral conductor drainage plate fever. 500 kilovolt Guodai 5611 line transmission line is Xuzhou, "North to South" an important channel, bear the eastern Xuzhou area and Suqian area of ​​electricity supply. The line span across the Beijing-Shanghai Railway, in order to eliminate equipment defects in a timely manner, without affecting the safe operation of the Beijing-Shanghai Railway, the company after many studies and discussions, the decision to adopt live working to eliminate the defects.

On the morning of August 23, Zhang Changsong, the only ultra-high voltage and above charged working class in Jiangsu Province, led six members to the scene of the defect. As a squad leader, this assignment is both ordinary and extraordinary to Chang Changsong.

"This is our 1000th UHV and above live work, we must pay attention to safety." 9:40, Zhang Changsong station classes will be emphasized to everyone. Put on the shield clothing, bring live working tools, team members in the permanent boarding line to start homework. After an hour of hard work, the defects were successfully eliminated.

At 10:06, the squad member Du Xiwang operated the insulated arm-car and slowly raised his bucket to the height of 30 meters carrying him and his colleagues.

10:09, the car parallel to the running line of 500 kV Guo Dai 5611, Du Xi Wang quickly connected to the car at one end of the pile on the electric potential transfer rods, mounted on the 500 kV Guodai 5611 line C-phase conductor, so that insulated armored car with a live wire formed an equipotential, thus avoiding charged workers touch.

Subsequently, with the cooperation of Du Xun Wang, he swiftly climbed from the inside of the car into the 56,000-kilometer Guodie 5611 line and started to implement the job of eliminating and eliminating chores. Du Xiwang remained in the car and served as a high-altitude guardian.

"Slower speed, pay attention to shaking the wire, to maintain balance, good coordination between hands and feet." On the ground, Zhang Changsong said loudly. He admitted frankly that the classmates were much more self-confident and did not pay attention to details, so he kept a close watch on the ground for each live work.

In a few moments, Yoo-kun "walked" to the defect and sat on the 4-legged wire. He bent down, untangled a screw on the wire guide, removed the emery cloth from the tool bag hung on his neck, and carefully polished the dirt on the surface of the draft plate.

After 15 minutes, the work is over and the workaround is done. Carefully inspect it for a while, then spread the conductive grease evenly over it.

After nearly 1 hour of intense work, the completion of the missing job in Yong. "Each subconductor has a current of 200 amperes and a current balance of four subconductors." After taking a clamp-on ammeter at Yong-jung and measuring C-phase split conductor of tower No. 1, tell Chang-sung Chang.

Eleven o'clock, in the everlasting climb from the wire into the insulated arm car bodywork. Accompanied by a shrill arc, Du Xi Wang remove the insulation attached to the arm and the charged wire between the potential transfer bar, the insulation arm bucket slowly down.

Although at work at high altitude, Yu Yong has drank two bottles of water, but after he got to the ground, he still seized the mineral water bottle for his first replenishment. Zhang Changsong helped him take off the total weight of 3.5 kg of shielding clothes, personal flame retardant underwear and conductive shoes, hands twist a twist flame underwear, sweat spilled a place.

"Report Power Dispatching Control Center, the line defects have been eliminated, personnel, equipment has been evacuated." 11:06, together with the class members to pack up good equipment, Zhang Changsong took out his cell phone to the East China Power Grid Power Dispatching Control Center made report.

It is reported that Zhang Changsong led the high-voltage live working class has completed 1,000 ultra-high voltage and above live operations, a total of 40,000 lines of power cuts have been reduced, the company has directly created a lot of economic benefits, Zhang Changsong has become involved in Jiangsu Province 500 kV and Those who have the highest number of live jobs.
