Guowangsha County Power Supply Company: Evergreen overnight to eliminate shortages to ensure the safe operation of the power grid!

On July 25, the Power Supply Company of Guowang Sand County used the laser cannon to remove the wrapped lines for the first time on the 35 -kilovolt East High Line, eliminating major security hazards, ensuring the safety and reliable operation of the power grid, and strengthening the power grid security.

"35 kV East High Line 3 BC BC has floating objects, and there are major hidden safety hazards." On the evening of July 25th, the power supply and operation and maintenance personnel of power supply companies in Shawangsha County was conducting peak summer temperature testing , Discovered a major hidden danger and reported it to the company's operational inspection department in a timely manner.

"At the current critical period of welcoming the peak summer, there are great hidden safety hazards in the high -voltage line suspension of foreign objects. Once the weather such as strong and heavy winds and heavy rain occurs, the plastic strip hanging on the high -voltage line will become conductive. The whole station of the Gaoqiao substation is involved in the seventh -level power grid incident. "After survey, the person in charge of the operation and inspection department of the Power Supply Company of Guowang Sha County is more difficult.

At this time, it is the peak of electricity. The power outage of power outage under high temperature and large load will directly affect the normal power consumption of more than 7,600 users in Gaqiao Town. After comprehensive analysis and judgment, the company considers the use of non -stop power -stop operations, and decided to request Sanming Power Supply Company Transportation Center for technical support.

At 23:20 that night, the support staff of the State Grid Sanming City Power Supply Company arrived at the scene with laser cannon, emergency lighting fixture and other equipment. The on -site work is divided into two groups. The lighting group is set up to set the lighting equipment to the plastic bar to provide sufficient lighting for plastic strips. The foreign body clearance group selects the appropriate location and angle to set up a "laser cannon".

At 23:40, operation and maintenance personnel began to eliminate defects. Under the light of the light, the "laser cannon" operating hand aims at the position of the plastic bar and operates the trigger switch. As a laser is emitted, I saw the plastic strip hanging point began to smoke, fire, decompose, and leave the wires, slowly falling dropped, and slowly dropped off. To the ground, the plastic strips hanging on the high -pressure line gradually disappeared.

At 0:15 the next day, after nearly an hour of intense operations, the foreign body on the wire was successfully removed, and the alarm that affected the safe operation of the line was successfully lifted.

This time is the Power Supply Corporation of State Grid Shatin District. Next, the company will increase the use of digital and intelligent means in the operation and maintenance of power grids to further enhance the safety and reliability of power supply.

Extended reading

The laser artillery foreign body cleansing instrument is referred to as "laser cannon", which uses ground laser equipment, fixed -point remote high -temperature cutting fuses on the overhead lines, realizing electricity, remote, non -contact operations, mainly by laser, electric gimbal, three tripods, tablets, computers , Module and other modules such as mobile power, ranging meter. The traditional obstacle clearance mode requires power outage or power operation. It not only has a long time, but also has a certain danger. The use of laser artillery foreign objects clearance not only reduces the risk of personnel operation, but also improves the lean operation and maintenance level of the transmission line. Stable operation is of great significance.
