Modern precision manufacturing has higher and higher requirements for the sustainability and stability of power supply. To this end, the State Grid Chibi Power Supply Company, as the “priority officer of economic construction” in Chibi City, took the initiative to plan ahead, scientifically plan the power supply grid, and strive to build a “safe, reliable, green” power grid, which has become an important driving force for the development of Chibi High-tech Zone.
At 19:25 on January 1st, the new 110 kV Nine Dragon Substation—Zhonghu Base newly built a 35 kV Weiwei second circuit and successfully launched power transmission, marking the first flexible screen manufacturer in our province, Vitali (Chibi) Co., Ltd. The Zhonghuo base will realize "zero flicker" power supply.
Vitali Industry (Chibi) Co., Ltd. was established in October 2015. It is a key construction project in Hubei Province. It specializes in the manufacturing of flat glass deep processing technology and equipment, and provides products and services for Apple, Samsung, Huawei, Xiaomi, etc. This enterprise is a precision manufacturing enterprise and has extremely high requirements for power supply reliability. Even if a millisecond-level power failure flashes, it will cause the product on the production line to be scrapped and cause huge losses. Therefore, it must ensure that the enterprise has "zero flash" power supply for 24 hours.
Vitali Industrial (Chibi) Co., Ltd. has two factories in Zhonghu and Chima Port in Chibi City. The power supply voltage is 35 kV, and the first-phase reported load capacity of 36.5 MVA has been put into production. In June 2019, Vitalite started the construction of the third phase of the project, with a newly installed load of 45 megavolt-amperes, which has a large demand for electricity and a tight schedule.
After the completion of Vitali's new construction and renovation project, its Chima Port base and Zhonghuo base changed from the original single-circuit power supply to a dual-circuit power supply and a three-circuit power supply. With strong support, it also provided a good guarantee for the expansion and expansion of the Zhonghu base. "Said Wang Zhi, project manager of the 35KV Vitali's new (reconstruction) line engineering project department.
During the construction period, the State Grid Chibi Power Supply Company overcomes the difficulties of short effective construction period and heavy coordination tasks. After more than 100 days of struggle, Vitali's new (reconstruction) power engineering project was completed on schedule.
Wu Gang, a person in charge of the Project Management Center of the Construction Department of Xianning Power Supply Company, told reporters that this project added a 50,000 main transformer No. 2 on the basis of the 50,000 capacity of the 1st main transformer of the 110 kV Yonglong Substation. A secondary circuit from Nine Dragons Substation to Vitali Zhonghuo Base increased the reliability of Vitali Zhonghuo Base and provided a guarantee for the development of high-tech zones in the future.
It is reported that the new 110kV Shaziling Substation-Zhonghuo Base 35kV Vitali Line and 110kV Luolong Substation-Zhonghuo Base 35kV Second-line Power Transmission Line in the supporting power facilities project of the Vadali Enterprise both went smoothly. The production and transmission of electricity, both the Vidali Zhonghu Base and Chima Port Base have achieved dual power supply and dual circuit power supply, effectively eliminating the worries of the enterprise.
In order to effectively protect the power source of industrial development, Chibi City will plan to add 1 500-kilovolt substation, 1 220-kilovolt substation, and 6-kilovolt substation based on the current situation of the power grid, load forecasting, and power demand research and judgment. Optimize grid structure.
