State Grid Henan Electric Power: Lean operation and maintenance high -voltage guarantee large power grid security

Since the beginning of the summer, there have been many rounds of high temperature weather in Henan. State Grid Henan Electric Power Company has adhered to the "first guarantee high pressure", comprehensively investigated and govern hidden dangers and defects, and strengthened equipment for the benefits of equipment. Inspection and monitoring, consolidate the foundation of the security and stable operation of the large power grid, and ensure the reliable supply of power.

In August, Henan Province continued to be high temperature. On August 5th, the 1,000 kV Nanyang substation operation and maintenance personnel launched high -temperature special patrols after routine inspections, focusing on observing the oil level of transformers and high -voltage electrical resistances, measuring the temperature of the oil pump, checking the operation of the air -cooled cold system, checking the communication and communication Whether the valve room status and the pressure of the pipe network of the valve room, the battery room, and the fire system are normal, and ensure the safe and stable operation of the special high -pressure equipment in the high temperature environment.

Henan Power Grid is in an important position in the east and south of the West Electric Power and the North to the South. Faced with the continuous high temperature since summer, the State Grid Henan Electric Power Company focused on Special high -voltage lean operations, and went all out to ensure the safety of power grids at all levels.

"Master Qiao, the temperature of the valve inlet is close to the high value." "Master Qiao, what other problems need to be solved by the board chart of the screen cabinet?" Early in the morning on August 2nd, Lingbao's back -to -back streaming station duty header and the operation and maintenance class The person in charge and party member Qiao Wangyu had been busy and assisted colleagues to carry out hidden dangers in the station. Since the beginning of the summer, he and 32 Communist Party members in the station demonstrated the hidden dangers and emergency repair work in the station to ensure that the daily transportation power of more than 1 million kilowatt -hours of electricity is running smoothly.

Before the beginning of the summer, the State Grid Henan Power promoted the hidden dangers of high -voltage equipment in accordance with the principle of "one trouble, one policy", and took the special operation of UHV power detection as the starting point to achieve the normalization of hidden danger inspection and governance. As of now, the company has detected 4128 UHV equipment and found 18 defects, which has improved the essential safety level of UHV equipment.

High -temperature weather and strong precipitation weather began in early June, which led to the long -term high -temperature and high humidity environment of Henan Power Grid, which increased the risk of operation safety. On June 15th, the State Grid Henan Electric Power launched the Peak Summer Safety Supply to provide a big duty operation mode. All the special high -voltage stations are stationed at the station to conduct uninterrupted inspections on the UHV transmission channels all -weather, and build a large power grid security line.

According to the requirements of the State Grid Henan Electric Power requirements, the State Grid Henan DC Center conducts scientific analysis of the characteristics of high -voltage equipment, and conducts differentiated operation and maintenance of key equipment to ensure that the equipment is in a healthy state. "We use online monitoring, charging detection, fully automatic inspection and other methods to diagnose real -time diagnosis, accurately grasp the operating status of the equipment, track the changes in key indicators, accurately evaluate risks, and carry out hidden dangers and defect disposal scientific and efficiently." According to Zhang Jun, the person in charge of the Henan DC Center, since mid -June, the center has implemented a total of 256 special high -voltage equipment special patrols, 78 special power detection, and 56 -time conversion transformers to cool down. Copy the test of multiple rounds of high temperature and high humidity weather.

Henan Power Grid currently has 47 500 kV power stations, covering 17 prefecture -level cities in Henan and 1 provincial county -level cities. Since the beginning of the summer, the State Grid Henan Electric Power Organization State Grid Henan ultra -high voltage company has strengthened the benefits of the equipment of the high -voltage close -up zone substation equipment, and increased the inspection of the 500 kV transformer station in 18 special high -voltage regions such as Guandu, Huiji, Jucheng, and Baihe The frequency, for the equipment that has been put into operation for more than ten years or hidden dangers in the station, formulate a list of key concerns, and regularly carry out centralized inspections and testing to ensure that the equipment is always in normal operation.

In terms of the operation and maintenance of the large power grid line, since the beginning of June, the State Grid Henan Electric Power has carried out special actions to improve the operation and maintenance protection of UHV transmission channels, completed the electrical transmission channel anti -ice -proof and lightning protection capacity school nuclear, and dynamically renovated the transmission channel "one way, one policy" The guarantee plan conducts a refined inspection of UAVs for UAVs and other high -voltage routes such as the 1,000 kV Hanyang Ⅰ and Ⅱ lines, involving the total length of the line 2087 kilometers. The company also applies for inspection robots, high -definition videos and other equipment to increase the frequency of inspection according to weather changes and load conditions, focusing on strengthening the operation and maintenance of 121 large power grid lines; deploying 1223 emergency repair teams, preparing various emergency materials to ensure high temperature temperature In the case of heavy precipitation, respond quickly and respond quickly and respond to it, and go all out to meet the needs of economic and social development and demand for people's livelihood.
