Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a box frame of an earthquake-resistant box-type transformer substation. Background Art

[0002] Box-type substation (also known as prefabricated substation or prefabricated substation) is a new type of complete set of power distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. Since the box-type substation organically combines the functions of transformer step-down and low-voltage distribution, there are certain requirements for the various properties of the box-type substation (such as moisture-proof, rust-proof, dust-proof, fire-proof, anti-theft, heat insulation, earthquake-resistant, etc.).

[0003] The box frame of a box-type substation is usually a steel structure, generally made of steel materials such as channel steel, angle steel, flat steel, etc., which is formed by welding or bolting. In order to improve the seismic performance, buffer materials or convex columns are installed at the bottom of the substation in the prior art. However, in reality, the box frame of the substation is still affected by seismic waves, causing the top frame of the box frame to vibrate, thereby causing the crossbeams constituting the top frame to displace, affecting the stability of the box frame.
