Illegal construction into grid rated threat

In today's era, electricity is indispensable. Regardless of the civic life or factory production, the role of electricity is crucial. However, the acts of destroying electricity have occurred from time to time, and the security of the power grid is increasingly threatened. Barbaric construction, hydrogen ballooning, high pole plants, etc., may all be the "murderers" that cause grid power outages.

At present, traffic engineering projects in Foshan are highly concentrated. The main projects under construction include the Guangzhou-Zhuhai Railway, Guizhou-Guangzhou Railway, Guangzhou-Foshan Light Rail, Guangzhou-Zhuhai Light Rail, Hong Kong-Shenzhen-Guangzhou Railway, Nanguang Railway, Taiao Expressway, Zhuerhuan Expressway, Fokai Expressway Expansion, and Guangsan Expressway Expansion. And 36 municipal road construction projects. According to statistics, there are a total of 151 “black spots” managed in the construction of transmission line protection areas, and are highly concentrated in the two areas of Nanhai and Shunde.

Taking Shunde as an example, the Power Transmission Department of the Foshan Power Supply Bureau introduced that there are many road construction projects in the area. Many projects such as the fast-moving Fochang Road, Longle Road, Guangming Expressway, and South Second Ring Road are underway. Some of the projects will be held before the Asian Games. Or finish earlier. There are tight schedules and pressures. Violent construction and illegal construction often occur.

At about 9:00 pm on June 24th, the power line inspector Shu Yingjun found that the construction workers were illegally pouring cement into the circuit protection zone in the second roundabout of Shunde. After discovering the situation, the inspector stopped the construction for the first time. Shu Yingjun said: "This illegal construction will not only endanger the personal safety of construction workers, but it may also cause widespread power outages, resulting in disastrous consequences."

“The destructive power of the barbaric construction is serious.” According to the power supply department, only 24 external power transmission trips occurred on the Foshan transmission line in 2009, 18 of which were caused by illegal construction. According to the statistics, on May 7th this year, the transmission line tripped 10 times, among which four trips occurred due to illegal construction.

The camera playback cable was cut off and power was cut off for 1 hour. It was the time when the power load was tight. On the night of July 5th, Hejiang District of Hecheng Street in Gaoming District suddenly fell into darkness, and the normal power supply was smoothly resumed after one hour of emergency repairs by the Gaoming Power Supply Bureau. After investigation, the blackout was caused by the harsh construction of the road project.

According to the power supply department, at 21:51 on the 5th, the Gaoming Power Supply Bureau found that the Hengwei line 702 switch trip protection trip, the dispatcher tried to coincide. Subsequently, the Gaoming Power Supply Bureau immediately organized emergency repair personnel to quickly go to the 10KV Hengwei Line of Rende Station in Hejiang Area to conduct a full line of faulty inspections. It was found that the cable of this section of the section crossing the Taihua Road was hooked by the construction unit that was undergoing drainage renovation. Excavation damage.

After finding out the fault, the emergency repair team immediately organizes the manpower equipment to repair the part, disconnects the cable branch box switch, isolates the faulty cable, and replaces the isolation knife breaker damaged by the short-circuit current. After 50 minutes of repairs, after passing the line to conduct insulation monitoring, the dispatcher is notified to resume power supply. By 22:54, the entire 10KV Hengwei line resumed power supply across the board.

Gaoming Power Supply Bureau stated that the duration of the power outage lasted 1.05 hours, causing 26 medium voltage subscribers to lose power and causing the breakdown of the incoming cables of the nearby rural credit cooperatives. After a preliminary investigation, the power outage was caused by the construction of a drainage reconstruction unit that did not have the night operation, and the municipal engineering supervision was not in place, resulting in the cable line being cut off and destroyed.

Lawyers claim that there is a possibility of sentencing lawyers to destroy electric equipment. According to the “Electricity Law”, if the electric power is destroyed and the public safety is jeopardized, serious consequences are not yet imposed, and a sentence of imprisonment of not less than three years but not more than 10 years shall be imposed. Article 110, Destruction of Electricity Gas If equipment and equipment cause serious consequences, they shall be sentenced to fixed-term imprisonment of not less than ten years, life imprisonment or death. If the negligent offender commits the crime mentioned in the preceding paragraph, he shall be sentenced to fixed-term imprisonment of not more than seven years or criminal detention.

At the same time, according to the “Interpretation of Certain People's Courts on the Specific Application of Law in the Trial of Criminal Cases Concerning the Destruction of Electric Power Equipment”, if negligence damages electric power equipment and causes serious consequences, according to the relevant provisions of the Criminal Law, it shall be sentenced to more than three years and seven years for negligent damage to electric power equipment. The following sentences shall be imprisoned; if the circumstances are minor, the sentence shall be imprisonment or criminal detention less than three years. "If the power department sues for accountability, it means that the destroyer is in jail."

The Regulations on the Protection of Electric Power Facilities specifies the area within the two parallel lines formed by the sidelines of the conductors of an overhead power line extending outward. The extension distance of voltage lines at all levels is generally as follows:

1 to 10 kV -5 m 35 to 110 kV -10 m 154 to 330 kV -15 m 500 kV -20 m underground cable power cable protection zone, 0.75 m on both sides of the line The area within the two parallel lines formed;

The submarine cables are generally two parallel lines formed on both sides of the line (100 m on both sides in the port), and the river cables are generally not less than two parallel lines formed on both sides of the line (100 m in both the small and medium rivers, generally not less than 50 m each). Within the waters.
