In recent years, more and more prefabricated substations have been used in the transformation of urban power grids and 12kV terminal substations in rural power grids in high-altitude areas of western my country, which are not only convenient for construction and installation, but also do not require too much land for building. Its technical parameters and functions, as well as major equipment such as c-gis, mostly conform to the national standard GB/T17467. The regulations in 1998 promoted the development of power grid technology and equipment, and were welcomed by the operating department.
However, there are also some high-voltage power distribution devices and integrated automation systems of 12kV pre-installed substations, which are closed by a common shell or a group of shells.
There is a big gap between the connotation of main components such as high-pressure inflatable cabinet equipment and GB/t17467-1998. At present, users generally put forward new requirements for the mechanical life and electrical life of 12kV c-gis.
Therefore, its manufacturing enterprises must not only strictly select product design, quality control, and manufacturing level; but also, in engineering design, the configuration of technical parameters, mechanical characteristics and operation methods must comply with relevant national technical standards, thereby promoting the overall level of electrical engineering. improve.
