Variable stations ice cubes auxiliary cooling power grid multiple measures to ensure summer electricity consumption

Cover Journalist Yang Bo Intern Wang Zixuan Photography Report

On July 6, the Chengdu Meteorological Observatory issued a high -temperature orange warning signal, and the rise in temperature also drove the grid load to rise. How to ensure the safety and stability of electricity during the summer during the summer, the reporter conducted a field visit.

At 2 pm, the reporter came to the 110 kV Guixi substation in Wuhou District, Chengdu. Its power supply range was mainly residents, industrial and commercial, and schools near the Zizi Park.

"Under such a high temperature, electricity equipment is also underneging in the scorching sun. On the other hand, with the increase in the load of the electricity load of cooling and air conditioning, the load rate of our equipment is also in a relatively heavy state." Guixi is transported Guardian He Zijun said that in order to ensure that the equipment is in a normal and healthy state, the staff will cool down the transformer.

How to cool the transformer? The reporter saw a device shaped such as "turret" at the scene. It connected a large box of water. In order to make the temperature of the water lower, a few ice cubes were added. The device can automatically spray water to cool the transformer.

"We will use such a water rinse tool to take a shower for the transformer every day." He Zijun introduced that he could take a "cold bath" for the transformer to maintain its temperature within a normal range. In addition to cooling, the staff also use infrared imaging equipment to measure electric equipment every day to ensure that each part of it is in the normal range.

In order to meet the demand for electricity growth, the State Grid Chengdu Power Supply Company has focused on promoting the new (expanded) construction projects for power grids on schedule. Up to now, the 500 kV Xingmeng substation 220 kV supporting project has been completed, and the 220 kV Mian'an dual -round line , 220 kV Three Saint Power Station expansion, 110 kV high -new new districts, Yixi River, Wenjiang New City District and other transformation and transformation projects, as well as 110 kV diligence, civil and military, tubes, Shiliba, etc. The expansion of the substation engineering effectively improves the power supply capacity of the grid.

In addition, the State Grid Chengdu Power Supply Company continued to carry out the transformation of the distribution network grid (dual power supply) of the distribution network (dual power supply). At present, there have been 168 interconnected and mutually supply lines, covering a power supply area of ​​91 square kilometers, benefiting more than 1,200 communities. At present, the State Grid Chengdu Power Supply Company has been prepared for personnel, supplies, vehicles, etc. During the high temperature load period, Chengdu Power Supply Company will inspect the power distribution equipment, continue to pay attention to the operating conditions of the equipment through infrared temperature measurement, and strictly implement the 24 -hour duty on duty strictly The system will ensure that the various types of faults will be put into repairs as soon as possible.
