Smart capacitance transformer has good effect of energy saving and emission reduction

On June 15th, the construction personnel of Jiangsu Yangzhou Power Supply Company was installing an intelligent regulated capacity distribution transformer in the Jiangsu Distribution Network Construction and Management Demonstration Zone in Yongqiao Village, Gongdao Town, Yangzhou. The day was the first day of the National Energy Conservation Awareness Week. The first batch of Yangzhou Power Grid equipped two transformers that can automatically adjust the working capacity between 400 and 125 kVA depending on the load change.

According to reports, at present, the power grid configuration transformer is configured according to the highest power load in the power supply area, while the distribution transformer works only at one-third of the time during the peak period of power use, and two thirds of the time is spent on the power load. Low level and valley period. The larger the transformer capacity in service, the greater the operating loss. Using transformers that intelligently adjust the working capacity according to the load size can achieve tightly matched power-saving and emission reductions. According to calculations, each transformer can save more than 9,000 kilowatt hours of electricity through intelligent regulation of its working capacity, demonstrating the broad prospects of energy-saving and emission reduction in the future.
