ZHENJIANG, China, May 27, 2024
/PRNewswire/ -- On May 23, State Grid
Zhenjiang Power Supply Company installed a total of 10
infrared probes at the entrances and exits of the cable layer as
well as the water pump control system in the 220 kV Guantang
Substation. As a result, all 21 low-lying 220 kV and below
substations in the Zhenjiang area have been fully enhanced in terms
of flood prevention capabilities.
In recent years, Jiangsu has
experienced frequent rainfall during the flood season. Under the
jurisdiction of State Grid Zhenjiang Power Supply Company, there
are 79 220 kV and below substations, 21 of which are located in
low-lying areas. In the event of heavy rainfall, water accumulation
can easily backflow into the cable layer, causing flooding in the
cable layer and substation.
To completely eliminate potential safety hazards, State Grid
Zhenjiang Power Supply Company conducted flood prevention facility
improvements at 21 substations, including the 220 kV Guantang and
Puqing Substations. The company inspected the substation buildings
for leaks, traced the drainage routes, cleaned the drainage
inspection chambers within the stations, and collaborated with the
Water Supply and Drainage Management Office of the Housing and
Urban-Rural Development Bureau to clear debris from the flood
control ditches and drainage outlets outside the stations, ensuring
unobstructed drainage channels. Additionally, the company
implemented flood prevention materials within the stations,
conducted water pump tests, checked the positioning of water pumps,
counted missing or damaged materials, and promptly replenished any
shortages. Furthermore, it revised and formulated flood prevention
plans for key substations, verified and posted flood prevention
measures, blocked off easily flooded cable trenches, repaired the
cable layer walls, and enhanced the flood prevention and disaster
resistance capabilities of the equipment. Targeted flood prevention
drills were also conducted, simulating flooding due to heavy
rainfall in key substations. The operation and maintenance
personnel promptly initiated emergency responses, blocked off the
substation entrances, and set up emergency drainage pumps to
eliminate water accumulation in the cable trenches and outdoor
areas.
