Suining in Sichuan: The "artifact" of the deformation of the substation of the substation

Recently, in the 110 kV Chicheng transformation station of the State Grid Suining Power Supply Company, the No. 1 Main 110 kV side 1011 knife gates and the main variable body 10 kV side tube were equipped with a set of blue. The cylindrical device, after understanding, this device is called "mobile cooling device", which mainly responds to the problem of thermal defects of the device.

In July, Suining continued to be high -temperature. The meteorological department issued many high -temperature orange warnings, which made many citizens say that it was really "inseparable from air conditioning." Under the large amount of accumulation of air -conditioning and electric fan, such as air -conditioning and electric fan, Suining Power Grid load has repeatedly renewed high. At the same time, the high temperature and high -negative environment also led to the heavy load operation of 110 kV Chicheng substation. The heating of equipment has become a major cause of the safe operation of the substation. In order to ensure the safe and reliable power consumption of more than 66,000 users in the supply area, how to quickly reduce the temperature of equipment and improve the power supply guarantee capability has become the first difficult problem for Suining's dream innovation studio.

Focusing on the theme of equipment cooling research, Suining Company's Dream Innovation Studio combined with good benefits, found ways and ideas. Through the brainstorming of professional and technical personnel, it was decided to use the "mobile cooling device" solution to solve the problem of equipment heating. Device ", this device mainly uses a shaft fans with a diameter of 46 cm. Unlike the general fan, its motor and wind leaves are in a cylinder. Etc.

The "mobile cooling device" is suitable for any environment, because the bracket of a fixed axis flow fan is composed of multiple porous bites of corner steel, which has sufficient stability and hardness. The hole positions evenly distributed on the corner steel not only facilitate the connection of corner steel brackets. It can also adjust the height, which is more convenient for fan installation. At the same time, this device can flexibly regulate the direction of the fan, reduce the vibration generated during the operation of the fan, and make the fan operation more stable; and the use of forced air circulation can also accelerate the air flow to achieve the effect of rapid cooling. For the shell of the heating equipment, the shell of the heating equipment It can be used with the cooling of the conductive site.

On July 13th, employees of Pengxi Transport and Inspection District found the temperature at the temperature of 110 kV infrared temperature measurement during the night infrared temperature measurement of 110 kV Chicheng substation. Under the influence, the temperature is on the rise. In order to cool down the knife gates and ensure the safe and stable operation of the equipment, the county power supply company immediately put the "mobile cooling device" into use. In just 10 minutes, the temperature was reduced by more than 40 degrees, and the cooling effect was obvious.

On July 15th, employees of Pengxi Transport and Inspection District found that the three -phase temperature above the soft connection above the low -pressure side tube of the No. 1 low -pressure side sleeve at the high temperature tour was as high as 130 degrees, which has seriously endangered the safe and stable operation of the equipment. With the last successful practical experience, the county power supply company once again used the "mobile cooling device" to cool down the heating equipment. The effect was immediate, and the temperature immediately decreased by more than 50 degrees. Two practices fully verify the physical cooling effect of the "mobile cooling device", and the soil methods have indeed played a great role.

The next round of high temperature weather is coming, and the State Grid Suining Power Supply Company will further implement various electricity preservation measures to welcome the peak and summer, and normalize the special patrol of the infrared and high temperature weather in the infrared and high temperature weather of the substation equipment. The "physical cooling" measures ensure the safe and stable operation of the power supply equipment, and make every effort to ensure that the customers in the area are worry -free.
