Building a strong "lifeline" of the power grid

——The State Grid Yulin Power Supply Company to conduct in -depth hidden dangers investigation and governance activities

Since June, with the continuous rise in the weather, the electricity load for residents has continued to rise, and the power grid has entered a peak summer stage. State Grid Yulin Power Supply Company uses large -scale machinery, stacking debris, trees and other hidden safety hazards in the protection area of ​​the electrical transmission line in its jurisdiction to carry out in -depth investigation and treatment of hidden dangers, effectively improve the safety level of the power grid, keep the safe production line of production, and go all out to do a good job of doing a good job. Welcome to the summer to ensure the reliable supply of power and the safe operation of the power grid.

Strictly guard against death

The 330 kV Suo Shen II line is one of the main "lifeline" of the northern part of Yulin. The line channel environment is complex and diverse, which has brought tremendous pressure on the safe operation of the transmission line. During the inspection, the company's transfer inspection center found that there were construction behaviors below the tower guide line 37 to 38 and in the protected area. The Shenmu Renewal Resource Market under construction is a concentrated area planned by the Shenmu area. The company actively connected the construction management department, found out the construction scope, planning, and progress, increased the inspection efforts, should do a good job of pre -control measures, strictly prevent the occurrence of accidents outside the line, carry out differential inspections of lines, and strengthen the control of dangerous sources. Install 3 sets of electrical visualization platform channel monitoring at the construction site, build 8 pieces of various types of safety warning signs, sign a notification of hidden dangers with Shenmu Renewal Resource Market, conduct safety warning publicity and education in the market, arrange arrangements, arrange arrangements Specifies the guardian and guarding the person in charge of the safety of the site at any time, inform the construction safety distance and precautions to avoid hidden safety hazards caused by mechanical operations.

Since the beginning of this year, the company has found a total of 164 hidden dangers of mountain fires, 78 key hidden dangers in birds, and 132 external risks, and issued more than 130 hidden dangers in the key hidden dangers of birds. The anti -exposure brochures and other methods have carried out more than 40 safety education and training, and improved 45 towers and line warning signs to effectively build a security protection network.

Hidden dangers of three -dimensional inspection

Relying on the construction of the transmission visualization platform and the intelligent drone inspection platform, the digital and intelligent transformation of inspections are gradually realized. The company's transfer inspection center takes the drone intelligent inspection as the starting point to fully carry out the lean inspection of the drone, and achieves 35 kV to 330 kV lines of 652 airline collection and route planning to complete the line autonomy Inspection and lean inspection. Combined with the line channel conditions, the construction of 132 sets of electrical visualization platform channels was added during the construction of the construction outside the construction and the three -span area plan. 37 sets have been completed. 6 sets of dynamic loading devices for the heavy load lines are installed. The identification technology conducts intelligent analysis of the channels of the channel, and the online hidden dangers are monitored in real time. The cycle of the original person's inspection length of up to 1 to 3 months has been shortened to 3 to 7 days, which greatly improves the inspection efficiency. In addition, the company has focused on the construction of integrated, refined, and intelligent inspection projects, and has planned to complete more than 30 unmanned airports.

As of now, the company's 18 RTK intelligent inspection drones are covered by 35 to 330 kV of the area of ​​35 to 330 kV of more than 20,000 pictures. More than 300 places, a total of more than 700 kilometers, takeoff more than 300 times, and the passage of 100 times, effectively establishing a three -dimensional inspection prevention and control overpaster control network control network.

Hidden dangers of territorial coordination

Continue to deepen the advantages of the territorialization of the channel, strengthen the discovery and coordinated disposal capacity of 15 counties (districts) companies in 15 counties (districts), and implement measures that endanger the safety behavior of the line safety. Squatting control measures, increased line channel inspection coverage, coordinating the owner's unit to install the line protection area forced isolation measures, actively connect the local government and emergency management departments, and urge relevant government authorities to coordinate and resolve hidden safety hazards on the spot. Closed -loop governance to ensure the safe and stable operation of the line.

As of now, the company's transmission and operation center has completed a total of 652 11689 kilometers of line inspections. The cumulative displacement of more than 2,300 people and the per capita inspection length of 580 kilometers. Insufficient trees in the thunder lines and other channels, 16 agricultural mechanical cultivation, miscellaneous storage, and hidden dangers of construction machinery are coordinated with the hidden danger unit or responsible person. 16 copies, effectively improve the health operation level of equipment.
