On January 22, Fei Guangyue, Director of Ganduo Power Supply Station, Gaoyou Power Supply Company, Yangzhou, Jiangsu Province, and Wu Benzhao, Head of Operational Maintenance Collection Team, came to Ganduo Town Ganquan Village Agricultural Technology Distribution Station 3. Wu Benzhang took out his mobile phone and clicked on it for several times. The distribution transformer in front of him made a "thump" sound. "Get it done!" What is Wu Benzhang doing? Transformers can also be controlled by mobile phones?
"The capacity of this transformer has been adjusted from 400 KVA to 125 KVA." Wu Benzhang said that they had just implemented capacity reduction operation on the light-load transformer, which ensured the economic operation of the transformer.
There are many fish and shrimp ponds in Ganduo Town, which have large power consumption and high load in summer. In winter, when the power consumption and load drop, the transformer with large capacity will appear light load and high output voltage. In the past, to adjust the transformer voltage, the power supply staff should notify the customers first, then climb up the transformer to adjust the adapter after the power outage. The fastest time to complete the whole set of operations is 20 minutes, which also affects the power consumption of the customers. If we want to reduce the capacity, we have to change the transformer, which is time-consuming and laborious.
In August 2018, Gaoyou Power Supply Company installed 10 on-load automatic capacitance and voltage regulating transformers in Ganduo Town. Now, as long as the transformer is within 50 meters, the voltage and capacity can be adjusted on the mobile APP, not only in a minute or two, but also without power stopping.
"These 10'control'intelligent transformers not only save power supply workers time and effort, but also avoid power outages. Next, we plan to gradually promote them in other towns with fish and shrimp ponds." Zhou Guozheng, deputy director of the company's operations and maintenance department, said. (Lin Huapeng)
