Nanchong, Sichuan: "Electric Butler" launched to escort the cool start of the school season

On the morning of August 26th, at a primary school in Xichong County, Nanchong City, Sichuan Province, Wang Desheng, an employee of State Grid Nanchong Power Supply Company, explained to the school electrician that the metal sheet of the socket had oxidized and the contact resistance had increased, making it easy to generate heat and requiring immediate replacement. As the autumn semester approaches, this "red vest" team shuttles through major campuses in the county, presenting a special "opening ceremony" to teachers and students.

During the summer vacation, the school's electrical equipment is idle for a long time, and the lines are affected by high temperature and humidity, which can lead to hidden dangers such as insulation aging and poor contact. Nanchong Power Supply Company has deployed in advance, organized Communist Party member service teams to go deep into primary and secondary schools in the jurisdiction, carried out special electricity inspections for the "escort to the start of the school season", and made every effort to ensure the safety of campus power supply.

At City No.1 Primary School, the team members carefully inspected the classroom lighting, air conditioning sockets, and multimedia equipment wiring to see if the insulation layer was damaged and if the joints were loose; Go deep into dormitories, teacher offices, and various workplaces to inspect and eliminate electrical equipment such as kettles and computer plugs that are prone to incorrect electrical habits; Conduct comprehensive temperature checks on transformers, switchgear, and leakage protection devices in the distribution room. In the morning of that day, the team members inspected more than 600 meters of power lines, more than 30 socket switches, dealt with 6 insulation aging hazards on site, replaced 2 malfunctioning and leakage protection switches, and guided the rectification of 2 hidden dangers in specialized transformers. All questions should be checked and corrected immediately, and checked and supervised immediately.

The external power supply guarantee on campus is being synchronously promoted. The team members used infrared thermal imaging devices to measure the temperature of multiple points related to the school's power lines, transformer cable joints, ring main units, and pole switches. They closely monitored the operation status of transformers, compared historical load data, and developed load adjustment plans in advance for lines that may be overloaded, ensuring smooth power supply during peak hours after school starts.

In this service, Nanchong Power Supply Company has also established a refined and long-term service mechanism. The team members updated the "one school, one file" ledger on site, recording in detail the model, service life, maintenance history, and load curve of the power distribution equipment. They also designated a "dedicated power manager" for the school to provide "one-on-one" services. If the school encounters a power failure, it can directly contact the dedicated manager, respond immediately, optimize the process, and quickly solve the problem. The logistics manager of Chengyi Elementary School said, 'Any electricity problems can be solved with just one phone call now, and I feel much more at ease.'.

Not only should we 'teach people how to fish', but we should also 'teach people how to fish'. After the investigation was completed, the team members set up a "micro practical classroom" for the school electrician, providing hands-on guidance on the correct holding angle of the infrared thermometer, the optimal distance for temperature inspection, and how to distinguish between interference signals and effective signals in partial discharge detection. Through theoretical explanation and on-site simulation, they helped the school improve its daily inspection and initial hidden danger disposal capabilities, and further moved the safety line forward.

As of now, Nanchong Power Supply Company has completed pre school electricity inspections for 146 primary and secondary schools in its jurisdiction, and assisted in rectifying 178 hidden dangers. Next, the company will organize a themed activity called "Safe Electricity in Campus" in conjunction with the autumn safety electricity promotion. Through fun classes, interactive Q&A sessions, and other forms, the company will popularize scientific electricity knowledge to teachers and students, allowing safety concepts to take root on campus.
