Electric power grid telegraph pole

Abstract

The invention discloses an electric power grid telegraph pole which structurally comprises an amplitude limiting damping frame, a wind resistance flow division ring, a balance rod and a grounding cone, wherein the bottom of the amplitude limiting damping frame is connected with the balance rod. The electric power grid telegraph pole has the beneficial effects that on one hand, the elastic potential energy of the amplitude limiting damping frame is used for bending the structure arc; the fracture because the structure cannot resist wind power impact force is avoided, so that the continuous worsening of abnormality conditions of an electric power transmission electric wire suffered from wind power stretching can be prevented; on the other hand, the wind resistance flow division ring is usedfor realizing the isolation on the wind power impacting the surface so as to achieve the goal of flow division; meanwhile, the gravity center of the telegraph pole is maintained to be always vertically downward through the balance rod; and the gravity center deviation at the bottom of the balance rod is regulated by a special structure that the weight of a gravity center pulley structure is incoordinate, and the inclination speed acceleration of the telegraph pole is prevented.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power grid utility pole. Background technique [0002] Assembled cement poles are widely used in power grid construction due to their economical price and convenient assembly. However, due to their own conditions and the influence of the field environment, the welding quality of cement poles has not been effectively guaranteed, especially in coastal and windy areas. , when the wind force passes through the distribution area of ​​the power grid during the movement, it will form a vertical horizontal impulse on the surface of the pole body, and the position of the pole will maintain a fixed angle during long-term use and suffer from wind impact Under the high-intensity wind force, the pole body tilts gradually, and the pole body tilt will cause the tension of the wire to tighten or even break. Based on the above premise, a power grid pole is developed in this case to solve this prob...

[0002] Assembled cement poles are widely used in power grid construction due to their economical price and convenient assembly. However, due to their own conditions and the influence of the field environment, the welding quality of cement poles has not been effectively guaranteed, especially in coastal and windy areas. , when the wind force passes through the distribution area of ​​the power grid during the movement, it will form a vertical horizontal impulse on the surface of the pole body, and the position of the pole will maintain a fixed angle during long-term use and suffer from wind impact Under the high-strength force of the wind, the pole gradually tilts, and the pole tilt will cause the tension of the wire to tighten or even break. Based on the above premise, this case developed a power grid pole to solve this problem
