Description

Technical Field

[0001] The invention belongs to electric power facilities, in particular to a method for calculating the center of a conical pole. Background Art

[0002] The determination of the pole weight center is a very important link in power engineering, which affects the use and installation of poles. The first is safety in use, ensuring that the installation position of the pole will not cause safety hazards to pedestrians, vehicles or the surrounding environment. Secondly, it affects the structural stability of the pole. Accurately determining the center position of the pole helps to ensure its structural stability and bearing capacity; the pole needs to withstand external forces such as the tension of the wire and wind load. A reasonable position can reduce the risk of tilting or collapse caused by uneven force. Third, it affects electrical performance. Correctly setting the pole center helps optimize the design and layout of power lines, such as maintaining appropriate phase-to-phase distance and ground distance to meet electrical insulation requirements and prevent short-circuit accidents. The fourth is construction convenience. During the construction process, clarifying the center point of the pole can simplify the installation process and improve work efficiency. It is also conducive to subsequent maintenance work and facilitates the rapid location of fault points. The fifth is beauty and neatness. Neatly arranged poles are not only beautiful, but also enhance the image of the city. Therefore, it is very necessary to accurately calculate the weight center of the pole when constructing and maintaining power facilities.

[0003] The existing methods for calculating the center of gravity of poles vary according to the specific shape of the pole. For example, for cylindrical or conical poles, a specific geometric formula can be used to calculate the center of gravity. For example, for a perfect cylindrical pole, its center of gravity is located at its geometric center, which is half the length of the pole. In addition, if the mass distribution of the pole is uniform, that is, the mass density within any length of the pole is the same, then the center of gravity position of the pole can be calculated by calculus of the mass element at a certain point on the pole. In practical applications, the pole can also be divided into several small mass points, and then the above calculus formula can be used to solve it. In some cases, it may be necessary to determine the center of gravity of the pole through experimental methods, especially when the shape of the pole is irregular or the mass distribution is uneven. Summary of the invention

[0004] The purpose of the present invention is to provide a method for calculating the weight center of a conical pole. The weight center position of the method is measured and calculated from the tip to the root. The method is easy to calculate, has low cost, high accuracy and strong applicability.

[0012] The invention uses a calculus method to calculate the weight center of the electric pole, and has high accuracy and wide applicability when processing conical electric poles.

[0013] It is very important to accurately calculate and consider the center of gravity during the design, manufacturing and construction of the pole, which directly affects the stability and safety of the pole.
