Abstract

The invention discloses a 220kV transformer station secondary equipment prefabricated cabin comprising a rectangular parallelepiped prefabricated cabin shell in which three transverse bearing plates and a plurality of vertical support plates in cooperation with three transverse bearing plates are disposed. The three transverse bearing plates divide, from top to bottom, the inner cavity of the prefabricated cabin shell into a 220kV secondary equipment zone, a main transformer secondary equipment zone, an 110kV secondary equipment zone and a cable storage zone. Each of the vertical support plates is provided with four first cable holes passing through the vertical support plate from left to right. The four first cable holes are located in the 220kV secondary equipment zone, the main transformer secondary equipment zone, the 110kV secondary equipment zone and the cable storage area respectively. The number of the vertical support plates is 2 to 10. The 220kV transformer station secondaryequipment prefabricated cabin is small in occupied area, flexible in layout, high in space utilization rate, reliable in operation of secondary equipment, and reasonable in cable / optical cable laying.

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 ...
