Kunshan, Jiangsu explores the construction of agricultural matching line transformation and construction of mechanized construction operations

Digging, standing rods, installing horizontal burdens, radicals, tightening tension, restoration of insulation, disassembling, removal of silk, removing old rods ... What efficiency will be introduced in the whole process of mechanized operations? A 10 -kilovolt -equipped line -equipped line renovation project with 110 kV power stations implemented a full mechanized construction operation. On July 8th, the 188 astronomical line on Pengxi Road, Kunshan City, Jiangsu Province was successfully completed. As a full mechanized operation exploration of the renovation of agricultural distribution network lines below 20 kV in Jiangsu Province, Li Jun, deputy general manager of the State Grid Kunshan Power Supply Company of 1,000 kV high -voltage southern power stations and local line engineering After this construction, he said: "Exploring the mechanization and automation of the construction of the agricultural networking network is of great significance to the modernization of the top 100 cities in the top 100 counties. Create an emergency guarantee construction process. "

On the same day, Kunshan Meteorological Observatory issued a high -temperature yellow warning. The surface temperature of 9:15 reaches 46.7 ° C, and the surface temperature of the newly -established cement prefabricated wire rod is 60.2 ° C. However, the four electrical construction workers intercepted by the two long -armed bucket vehicles have been operating at the top of the new group at more than 30 meters high. Two groups of workers in the two long -armed buckets, two or two cooperation, expanded the complete leading operation, no climbing rod, no binding of the top of the electrical rod, no back to 90 degrees, 4 electricity electricity The workers were in the fighting vehicle sent and supported by long -arm loads, but in 15 minutes, the wires were tightened and expanded. In the past, this work link requires multiple people to cooperate with at least 2 hours.

Two hours ago, a small excavator completed the pole pit required for the vertical pole in only 5 minutes at the scheduled ground; a 25 -ton long -arm hanging car was lifted up with a 32 -meter -long cement prefabricated wire. The pole immediately "implanted" the pole in the pit. After the small excavator is synchronized with the soil backfilling and compacting the operation, leave the scene, and the long -arm crane is "static" a standing posture until the work on the pole is completed.

A total of 2 long -term arms hanging vehicles, 3 director arm bucket vehicles, and 1 small excavator participated in the operation of the two -point electric pole. Six electric workers of the two teams in the "arm curvature" of more than 40 meters in their arms were conducted in an orderly manner to conduct tightening lines, fixing equipment, and turning on the wires. The operation is more laborious, and the hands and feet are more flexible due to the safe and spacious operation of the activity space.

As the largest and most density county power grid in China, Kunshan urban and rural areas have 95 substations with different lines. Only 20 kV and below agricultural network lines are close to 10,000 kilometers, directly serving customers with 1.2 million customers. Affected by the high temperature in the coming day, since July 7, the highest scheduling load of Kunshan Power Grid has a new high in the year, close to 4.9 million kilowatts. Upgrade and transformation, for the first time, tried all mechanized operations, which was two hours earlier than the original planned construction and power outage operations.

While exploring the use of all mechanized operations, while improving operational efficiency and shortening the power outage time, it greatly reduces the labor intensity and operational risk of power workers in high temperature weather. "In the past, power workers needed to board dozens of meters of high -electric poles to operate with their foot buckles. They were not only strenuous, but also easy to step on the air. The training alone took more than a week." Su Hairong, a commissioner of the distribution class project of Da Electric Power Construction Co., Ltd., said that the workers' bodies must always close the electric pole. Not only is the activity space limited, but it is easy to be burned by high temperature and frostbite in winter. It often takes an hour to change a shift.

Yu Xuezhong, who has experienced more than 10 years of climbing work, has the most touching: "Now freedom of upper and lower, free movement, and the easier body. The most important thing is that you don't need to hold a 60 ° C electric pole, just work as on the ground."

It is reported that due to the early epidemic situation, the Kunshan Power Supply Company of the State Grid is stepping up the promotion of a series of power construction projects. During this year, more than a hundred large -scale construction projects were discharged. "We will continue to explore mechanized smart operations in multiple and multi -path. While reducing labor density, improving the construction conditions of power workers, improving the safety factor, reducing the operation time, minimizing the impact of the power consumption of the project on the enterprise, and being Kunshan for Kunshan Economic and social development provides a strong power grid protection. "Pu Jianxin, secretary of the Party branch of Kunshan Shunda Power Construction Co., Ltd., said.

"Human -machine's more coordinated workflow preparation and improvement and special design of special equipment have room for improvement." Li Jun said. On the same day, Xu Ji Group Co., Ltd., which belongs to China Electrical Equipment Group, sent a commissioner to observe the all -mechanized construction operation on the spot. Zhang Shouju from Xu Ji Group Jiangsu Marketing Service Center said that the full mechanization of agricultural networking and even automated construction provides unlimited imagination for the innovation and market development of the equipment industry.
