"It's about to be the New Year, this year there is a lot of snowfall, or to have a targeted analysis of the adverse impact of snowy weather on substation equipment, to be foolproof!" Talking about the recent snowfall weather, Zhao Yue, head of the operation and maintenance team of the State Grid Shanxi Ultra-High Voltage Substation Company, said worriedly.
Near the Spring Festival, the winter snow in Yuncheng, Shanxi Province, fell, and the Loess Plateau was covered with snow. As the second-level power preservation main substation of the Winter Olympics, whether the Yuncheng 500 kV substation under the jurisdiction of the company is affected has become the most concerned thing for the operation and maintenance personnel.

In response to this matter, Zhao Yue held a meeting with colleagues to discuss, and the operation and maintenance personnel expounded their ideas and countermeasures. After some discussion, Zhao Yue breathed a sigh of relief. "Everyone's systematic summary and advance planning have made me more confident, and in the special period of the New Year of the Tiger and the Winter Olympics, we must do everything possible to make emergency preparations and strengthen special inspections."
According to the special operation and maintenance requirements, in addition to the Yuncheng 500 kV substation on daily duty, the other two Jishan and Tongxiang 500 kV unattended substations responsible for operation and maintenance in the class have been arranged to be specially guarded, and two O&M personnel have been arranged for each station, and the three stations have been scheduled to hold a video conference on time at 8 o'clock every night to summarize the day's operation and maintenance work and deploy the next day's work arrangements.
"Brothers, the snowfall outside has lasted for two hours, and we urgently need to complete two tasks now: one is to collect the operating parameters of the current main transformer, focusing on recording the temperature, oil level and other operating data of the internal winding of the main transformer; the other is to conduct a comprehensive infrared temperature measurement of the equipment. In particular, it is necessary to keep an eye on the equipment, heavy loads and large loads of equipment with previous fever defects..." Zhao Yue instructed in the video conference, and the on-site operation and maintenance personnel recorded each instruction of the squad leader in detail in the work record book.
After nearly two hours of video conference, it was nearly midnight, and the operation and maintenance personnel were tired and still completing the data collation and archiving work of the day.
The next day, before dawn, Huang Shuai, the operation and maintenance attendant, heard the voice of Su Pan, the chief of the outdoor duty. "Think again, is there anything missing?" It turned out that Su Pan was worried about the water leakage problem on the roof of the relay protection room that had just been repaired two days ago, and he got up early to check it out. (End)
