The peak season is an annual "big test" that the power grid faces, and it is the most difficult period for power supply services. In recent days, the temperature in Guangzhou has been consistently high. In order to ensure the reliability of electricity consumption for residents in Guangzhou during the summer, the Guangdong Guangzhou Power Supply Bureau of China Southern Power Grid has completed a distribution network investment of 3.2 billion yuan. By increasing the application of new technologies, increasing investment in uninterrupted power operations, and strengthening equipment operation and maintenance, emergency support capabilities have been improved to provide reliable, reliable, and cool electricity to the people in the scorching summer. What is the experience of "Little Yellow Man" working at a height of over ten meters for 2 hours under high temperatures, staying cool and refreshing outdoors at 38 ℃ in summer, wearing thick and breathable work clothes? There is a group of "little yellow people" who often shuttle through the streets and alleys of Guangzhou, guarding the safe operation of the power grid. They are the operators of uninterrupted operation. After the power grid equipment is put into operation, there will be wear and aging, and it needs to be regularly checked and treated. On August 4th, at Feng'an Second Street in Haizhu District, an old set of 10 kV zinc oxide lightning arrester on the electric pole needed to be replaced without power outage. Operation without power outage belongs to a special type of work, with high technical requirements and high labor intensity. Qiu Jinnan, the leader of the live line team of the emerging business enterprise Southern Investment Group of Guangzhou Power Supply Bureau, is the main operator of this operation. He is wearing heavy insulation protective equipment and has been working in a high-altitude environment for nearly an hour in high temperatures of over 30 degrees Celsius. He said, "Only by conducting regular 'physical examinations' of power grid equipment can residents have full power, which is worth the effort." "Previously, maintenance operations were mostly carried out after power outages," said Liang Guokai, the distribution network management department of Guangzhou Power Supply Bureau. With the development of the times, the power grid industry has been able to carry out maintenance and upgrading of power grid equipment through uninterrupted operation, which can effectively reduce the impact of maintenance outages on users. In the first half of this year, Guangzhou Power Supply Bureau has carried out over 17000 non power outage operations, fully ensuring the safety and stability of power supply to the power grid. The "no perception" access to black technology provides a new experience in electricity usage. However, not all maintenance scenarios are applicable to live working technology. For example, in the renovation of a switch room, it is necessary to use a low-voltage generator to provide emergency power. During the process of transferring low-voltage power generation vehicles, two switching operations are required, which can still result in a short-term power outage. The staff of Guangdong Guangzhou Power Supply Bureau of China Southern Power Grid carried out an emergency power generation vehicle with no perception of grid connection at the work site. On August 2nd, Du Juzhou took a photo of Xiaomei Street in Liwan District, Guangzhou. With the continuous supply of electricity from low-voltage power generators, the Guangzhou Power Supply Bureau applied user "no perception" fast access technology, making maintenance operations that originally needed power outages completely uninterrupted, and keeping nearly 600 households in the surrounding area cool for the summer. The Guangzhou Power Supply Bureau's application of the power generation vehicle perception free fast access technology, which involves adding a temporary power supply to synchronize the power supply while the original power supply is not stopped, and then removing the original power supply equipment for maintenance, ensuring that the power supply is switched without perception, ensuring that users can still use reliable electricity during equipment maintenance. In recent years, the development of new energy vehicles has been rapid, leading to the construction of charging piles, in order to solve the problem of old residential areas. However, in some old residential areas in Guangzhou
