Problems solved by technology
[0002] At present, the frame columns of the substation are mainly welded by concrete rods and the ends of the substation frame. The joints of the lower concrete rods all adopt the traditional process of "pre-embedded steel rings at the rod head and manual welding at the construction site", which has welding quality and anti-corrosion performance at the joints. Problems that cannot be effectively controlled, and there are potential safety hazards in the long-term operation of substations

The invention relates to an electric power supporting frame which comprises two flange-assembly type equal-diameter rods. The electric power supporting frame is characterized in that the upper ends of the two flange-assembly type equal-diameter rods are connected to the end of a framework respectively through a connector flange, the end of the framework is formed by a framework platform and two steel pipes welded to the bottom face of the framework platform, and a power transformation framework cross arm is arranged between the two flange-assembly type equal-diameter rods. The electric power supporting frame is good in overall corrosion-resisting effect, and the framework end of flange-assembly type framework columns and lower-portion concrete rods are produced in a factory directly, transported directly, and assembled on the construction site directly; welding on the construction site is avoided, the number of construction errors is effectively reduced, the safe connection between structural steel bars and internally-connected flanges is effectively protected, and therefore the overall quality of the power transformation framework columns is effectively ensured; in addition, the strength performance of the rod body can be effectively protected.
Description
technical field [0001] The invention relates to an electric support frame, which belongs to a frame column of an electric power substation. Background technique [0002] At present, the frame columns of the substation are mainly welded by concrete rods and the ends of the substation frame. The joints of the lower concrete rods all adopt the traditional process of "pre-embedded steel rings at the rod head and manual welding at the construction site", which has welding quality and anti-corrosion performance at the joints. Problems that cannot be effectively controlled have potential safety hazards in the long-term operation of substations. Therefore, it is the object of the present invention to study the above problems. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the multi-point joint welding technology for substation frame columns, and provide a power support frame that can significantly improve anticorrosion a...
