"Pulse diagnosis" to prevent equipment "heat stroke", Shanghai Power Grid strengthens special patrol operation operation

In the past few days, with the new high after the temperature reached the summer, the demand for power consumption has continued to rise. The reporter learned from the State Grid Shanghai South China Power Supply Company that in order to ensure the stability and reliability of power supply, the company entered the state of confession to protect the power, and made a preparation plan in advance. , Each departments have fully carried out the special equipment tour and hidden dangers to investigate, and fully carry out the responsibility of guarantee.

"A -phase lightning avoidance ear wiring ear 47.5 ° C, B phase 48.2 ° C, C phase 47.7 ° C, the temperature is normal." At 14:00 on July 8th, Tang Benchao, a team member of the Power Inspection Inspection Inspection Inspection Inspection Inspection Inspection Company of State Grid, came to A special patrol route on Xindong Road, Minhang, using infrared detectors to detect the real -time temperature of the line equipment. This is also the third special patrol route they inspect today.

In the case of aging and poor contact, the power supply equipment will cause hidden heat hazards. If it is not discovered in time, it will further induce equipment failure or even stick to the card. High temperature will accelerate the occurrence of this defect. The 131 lines and 72 -seater transformation power stations involving the middle and college entrance examinations and high -temperature electricity have been carried out.

Combined with real -time monitoring load growth, operation and maintenance personnel are inspected key equipment through infrared temperature measurement and charging detection, and accurately judge the operation of the equipment through the operating parameters of the equipment temperature, voltage current, etc., and timely summarize the equipment defects and problems that affect the safe operation in a timely manner. Report and take the timely disappearance. In response to the situation where the trees are unable to observe the equipment or epidemic prevention areas, the operation and maintenance personnel will also conduct online inspections based on the drone and remote monitoring camera to ensure that the surveillance is full coverage and the special patrol no dead ends.

At the same time, the city and South Company analyzed historical data, and the power distribution transformers with high load and excessive loss of high temperature days of high -temperature days were used to take effective measures to "diagnose the pulse" in advance. The hidden dangers are eliminated in the bud, and the power grid equipment is fully guaranteed to run safely and reliable during the peak of the summer load.

Considering the characteristics of short -term rainfall weather in the summer, the operation and maintenance personnel of Shinan Company have also strengthened the inspection of the flood prevention equipment such as the cable holes of the underground change power stations, the flood control sandbags, and the flood prevention. In place to ensure that the grid equipment is running reliable under extreme weather.

From 17:00 on July 8th to 17:00 on July 9th, Shinan Company arranged a total of 10 electricity reservation teams and 120 personnel. It carried out 92 and 132 equipment for special patrols and inspections. There are 86 guards on duty, 52 vehicles, and the regional grid operation is stable.
