Abstract

The invention discloses a frame structure of an intermediate-voltage cabinet and an intermediate-voltage cabinet. The frame structure comprises a cuboid frame formed by an upper frame, a lower frame, two front vertical beams, and two rear vertical beams. The upper frame includes upper front and rear cross beams and upper left and right cross beams; the lower frame includes lower front and rear cross beams and lower left and right cross beams. The frame structure consists of triangular support frames arranged at right-angle connection parts of the upper frame, the lower frame, the front vertical beam, and the rear vertical beam, a left middle vertical beam connected to the upper left cross beam and the lower left cross beam, a right middle vertical beam connected to the upper right cross beam and the lower right cross beam vertically, a lower middle cross beam connected with the lower left and right cross beams vertically and the left and right middle vertical beams vertically, an upper middle cross beams connected with the upper left and right cross beams vertically and the left and right middle vertical beams vertically, a middle front cross beam connected with the two front vertical beams vertically, a middle rear cross beam connected with the two rear vertical beams vertically, and a front middle vertical beam connected with the middle front cross beam and the lower front cross beam vertically.

Description

technical field [0001] The invention relates to a medium voltage cabinet and its frame structure. Background technique [0002] The seismic resistance of nuclear power plants is an important issue to be considered in the design of nuclear power plants, and the seismic strength of electrical equipment must meet the requirements of nuclear power plants. However, the existing medium-voltage cabinet generally adopts an integrated structure of aluminum-zinc clad plate, and the whole cabinet is completed by bending the aluminum-zinc plate. The structure of the medium-voltage cabinet is simple and easy to process and produce, but the seismic strength of the medium-voltage cabinet is low. , unable to meet the seismic requirements of nuclear power plants for equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a frame structure of the medium voltage cabinet and the medium voltage cabinet in order to overcome the de...
