Abstract
Description
technical field
[0001] The invention belongs to the technical field of substation secondary equipment, and in particular relates to a prefabricated cabin for 220kV substation secondary equipment. Background technique
[0002] Substation secondary equipment such as relay protection provides an important guarantee for the safe and stable operation of the power grid. 220kV substation secondary equipment screens are generally arranged in the main control room, such as 220kV line protection screens, 110kV bus tie protection screens, 110kV bus protection screens, main transformer measurement and control screens, etc., with different functions and different voltage levels, resulting in the number of screen cabinets Many, covering a large area. There is a cable trench under the screen cabinet, which is used to connect the primary equipment area and the main control room. During the design and construction of cable trenches, civil engineering majors and electrical secondary majors ...
