Polaris Smart Grid Online News: Recently, giant "containers" came to the 110kV Tongfu Power Transmission and Transformation Project site in Nantou Town, Zhongshan City, Guangdong Province, and were built like building blocks, marking the first batch of prefabricated Guangdong Power Grid Cabin smart substation is about to enter the equipment installation stage.

 

The prefabricated substation realizes the organic combination of electrical equipment and prefabricated cabin equipment. It adopts the integrated distribution and transportation of cabins, and at the same time achieves safe and standardized station construction, reduces the amount of on-site construction, and meets the requirements of rapid station construction. This mode is cost-effective in time and civil construction. It has obvious advantages in terms of construction volume.

 

The so-called prefabricated cabin-type substation means that the entire substation is composed of “containers”. All switch cabinets, primary and secondary equipment, as well as the cabin body are prefabricated in the factory, and they are installed and debugged in the factory and directly hoisted on site, just like Lego blocks. be usable. Sun Jingxian, deputy general manager of the project and logistics center, said: "Compared with conventional stations, most of the equipment installation work in substations is moved to the equipment factory. The excellent installation environment in the factory promotes the improvement of project quality and reduces the risk of project site operations. ."

 

However, because it is prefabricated in the factory, there may be a problem of equipment "unacceptable". Faced with these new problems, in the project design stage, Sun Jingxian, deputy general manager of the project and logistics center, and Qu Hua, manager of the engineering construction division of the asset management department, visited the prefabricated cabin manufacturers many times, organized the preparation of the prefabricated cabin equipment technical specifications, and carried out many times. Revise, discuss and clarify the division of the responsibility interface between the construction party and the manufacturer.

 

Substations must be put into operation before the peak of summer electricity consumption, which can relieve the pressure on the northern Zhongshan power grid. Speeding up is one of the biggest difficulties faced by the asset department, project and logistics center construction team. According to Sun Jingxian, after the prefabricated cabin manufacturer's bid, the project and the logistics center immediately organized the design and docking with the manufacturer, and carried out the drawing confirmation work. At the same time, the qualified process on the site immediately organized the construction unit to enter the site to carry out the construction operation.

 

The supporting lines of the Tongfu Power Transmission and Transformation Project pass under the Guangzhong River, the Guangzhu West Line and the Guangzhu Intercity Light Rail. How can the construction be more efficiently promoted without affecting the livelihood projects such as expressways and railways? This became the heart stone of Meng Fei, the project manager of the project department of the first owner of the Zhongshan Power Supply Bureau Project and Logistics Center. From the construction site to the relevant departments, and then from the relevant departments to the construction site, through countless discussions... He travels hundreds of kilometers a day and explains in detail the risk control measures for each link, and every detail must be cleared.

 

According to reports, after the prefabricated cabin substation is put into operation, the substation and line transfer capacity will be greatly strengthened, and the ability to deal with severe and extreme weather disasters will be improved.
