Problems solved by technology

Compared with the traditional open-air switch station configuration, the existing substation and distribution substations have reduced floor space, but the floor space is still relatively large, which does not conform to the national industrial land conservation policy, especially in areas where industrial land is extremely tight. protrude

Abstract

The invention discloses a configuration structure of a substation and distribution station in an alumina plant. The substation and distribution station is a left-right symmetrical structure, and the substation and distribution station is a three-story building with stairwells (9) at both ends; Two power distribution rooms (2) and one reactance room (7) are arranged in a square shape; the bottom layer of the two power distribution rooms (2) and one reactance room (7) is the cable sandwich room (1), and the The top floor of the electrical room (2) is the GIS switch station room (3), two transformer compartments (5) are arranged in front of the two power distribution rooms (2), and capacitors are respectively installed outside the two transformer compartments (5) Room (6), the top floor of the capacitor room (6) is provided with an isolating switch room (4). The invention changes the plane configuration of the existing substation and distribution station into a substation and distribution station with a three-story building structure. Under the condition of satisfying the electrical safety of the substation and distribution station, the occupied area of ​​the substation and distribution station is greatly reduced, and the problem of extremely tight industrial land is solved. It has good economic and social benefits.

Description

technical field [0001] The invention relates to a configuration structure of a substation and distribution station of an alumina plant, and belongs to the technical field of power supply and distribution in the nonferrous metal production industry. Background technique [0002] The configuration of the existing substation and distribution station includes a 220kV GIS switch station and a 10kV general distribution room. The GIS switch station is located at the front end of the step-down transformer in the 10kV general distribution room. The GIS switch station adopts an indoor one-story structure, and the incoming and outgoing lines are overhead; the 10kV general distribution room adopts a two-story structure, the first floor is a cable interlayer room, and the second floor is a power distribution device room. Compared with the traditional open-air switch station configuration, the existing substation and distribution substations have reduced floor space, but the floor space ...
