Core Viewpoint - The article highlights the successful upgrade of a transformer in Xiangshuidaba Village, Yunnan Province, which significantly improves the power supply capacity and reliability for local residents during the winter peak demand period [1][2]. Group 1: Project Overview - The Southern Power Grid Yunnan Qujing Lu Liang Power Supply Bureau implemented an innovative "live working + crane installation + emergency power supply" model to upgrade a 160 kVA transformer to a 250 kVA unit [1]. - This upgrade addresses the issue of transformer overload, enhancing the power supply reliability for the community during the winter and the upcoming Spring Festival [2]. Group 2: Community Impact - Residents expressed relief and satisfaction with the new transformer, noting that previous winter power supply issues have been resolved, allowing them to use high-power appliances without concern [2]. - The upgrade is seen as a "warm power gift" for the villagers, ensuring stable electricity supply during the cold season [2]. Group 3: Technical Execution - The old transformer had been in service for many years, and with the increasing use of high-power appliances, the demand for electricity had risen significantly, especially during winter [5]. - The Lu Liang Power Supply Bureau utilized a data monitoring system to identify the overload issue and developed a plan for live capacity enhancement without interrupting power supply [5][7]. Group 4: Operational Efficiency - The upgrade process was completed in just a few hours, maintaining power supply throughout the operation, which is a significant improvement over traditional methods that often require extended outages [7]. - Since 2025, the Lu Liang Power Supply Bureau has conducted 2,832 live working operations, achieving a non-power outage operation rate of 96.23%, significantly improving power supply reliability [7]. Group 5: Future Plans - As the Spring Festival approaches, the Lu Liang Power Supply Bureau plans to continue monitoring transformer loads and addressing overload risks to ensure reliable power supply for the community [8].
