Safety first smart grid security safeguards must Technology

"Do not underestimate these small irregularities, a long time will lead to disaster." Recently, in the operation of the power operation site safety inspection checks, State Grid Power Supply Company Shijiazhuang safety oversight group members will organize live video playback of irregularities issued a rectification notice requiring the relevant unit for rectification. Safety production supervision and management is the key. City power company actively innovative safety production monitoring techniques and tools, widely promoted in the professional application of electronic monitoring devices, through on-site supervision, "electronic eyes" to protect the personal safety and security inspection robot intelligence and security equipment, security video equipment to protect network security, electronic monitoring Equipment sang the leading role in the safety production.
Inspection robot device at any time for "physical"
Movie "WALL" in the naive, kind and sincere WALL image for him. So far, in Hebei province 220 kilovolt substation Korea, one like "WALL" intelligent robot has been officially "job" two months.
The "WALL" scientific name is called lc-gr1000 intelligent inspection robot, science and technology and methods set machinery and electronics, multi-sensor fusion, pattern recognition technology, wireless communication in one, using an infrared video camera and a visible light camera detection devices, by navigation and positioning equipment, pre-constructed in the station along a good track magnetic stripe on the designated point infrared temperature measurement and forecast data collection instrument.
"Although it was small, the ability to be plenty of money." Technician said, "WALL" in the station visits, eye pressure can automatically determine the switch, ct oil, arrester leakage current and a series of data, generate and upload inspection reports, comparative analysis through the background, promptly issued a defect alarm; outdoor equipment eye infrared thermometer can be found equipment malfunction automatically generates infrared spectra, while the alarm. Eyes see everything will be synchronized back to the control room, operation and maintenance personnel homes, publish patrol commands directly in the control room, you can get the robot inspection analysis and alarm information within just a few minutes to realize the substation remote fault identification.
It is understood that, "Wali" will be conducted once every two days, the station's outdoor equipment routine inspection and infrared temperature measurement, saving labor, vehicle costs, but also improve the quality inspection. Operation and maintenance personnel can be reduced inspection workload by 30%. Especially in unfavorable patrol officers arrived at the scene of the special circumstances, intelligent inspection robot can bring out a special role in providing security for the safe operation of electrical equipment.
Watch miniature camera production site
"There are cranes in the 110 kV Korea near the white line on the 13th column job, line patrol personnel to view." The company Transmission transport inspection chamber threat is found by security video surveillance device, they quickly issued directives site inspections. It is understood that an important section of the grid lines in Shijiazhuang, such "electronic bodyguard" a total of 26 units.
"The monitoring system consists of a plain white diameter cylindrical surveillance camera approximately 40cm, the two solar panels and a battery composed, install it in the ground about 15 meters from the tower location, you can back the remote camera rotates through 3g network Screen line the corridor back to the control center, to achieve real-time monitoring, rapid disposal, effectively reducing the impact of external factors such as damage to the safe operation of transmission lines caused. "firm transmission transport inspection chamber, said Xing grams.
Transmission line running across the field, over a broad area, in order to effectively prevent external damage, tower material loss, theft and so on, the city power company from 2013, important cross-cutting of the transmission line of external damage-prone parts of the installation of transmission line segments line monitoring equipment. These "electronic bodyguard" 24 hours on-line monitoring of transmission lines, especially in the high winds and other severe weather conditions, can grasp the operating conditions of the transmission line, provide the basis for failure determination and repair.
As of now, "electronic bodyguard" has been to detect and stop the line "three violations" phenomenon more than 50 cases, effectively protecting the security and stability operation.
