Adjustable power distribution circuit line-abandoning and rod-protecting apparatus

Abstract

The invention discloses an adjustable power distribution circuit line-abandoning and rod-protecting apparatus. The apparatus comprises an end cover, a sleeve, a fixed arm, a suspension column, a flying ring, a support rod and a buckle part; the upward side of the end cover is connected with an insulator on a telegraph pole while the downward side is fixed with the sleeve and the fixed arm; the upper end, which can slide up and down, of the suspension column is mounted in the sleeve; the lower end of the suspension column extends out of the bottom of the sleeve and is connected with the flyingring; an elastic apparatus is arranged in the sleeve, and the elastic apparatus is compressed between the top of the suspension column and the bottom of the sleeve; an opening is formed in the bottomof the flying ring; the two ends of the support rod are hinged with the flying ring and the buckle part respectively; the buckle part and the flying ring are buckled to enable the support rod to closethe opening of the flying ring; the upper end of the fixed arm is tightly attached to the outer wall of the sleeve while lower end is equipped with a check block in an adjustment manner up and down;and the check block is in collision with the buckle part to enable the buckle part and the flying ring to be separated so as to open the opening of the flying ring. The adjustable power distribution circuit line-abandoning and rod-protecting apparatus is capable of flexibly adjusting the wire releasing on-load critical value, applicable to multi-direction stress, and reliable and safe, and simplein operation.

Description

technical field [0001] The invention belongs to the technical field of power distribution line mechanical devices, and in particular relates to an adjustable power distribution line abandonment protection pole device. Background technique [0002] When the poles and wires of the distribution lines of the power grid are subjected to excessive loads, such as the distribution lines are subjected to excessive wind force in a typhoon, or the distribution lines are severely iced due to ice disasters, or foreign objects such as trees are pressed on the wires, etc., resulting in The tension on the wire is too large to exceed the limit breaking force of the distribution line tower, which will cause a pole down accident. [0003] Pole down accidents cause serious harm to the surrounding life safety and property, and at the same time increase the difficulty of construction repairs and the time to restore power supply, increasing the cost of repairs. Therefore, it is very necessary to ...

AI Technical Summary

Problems solved by technology

[0004] The existing wire abandonment protection pole device of the distribution line only considers the stress in a single direction, which is not suitable for the situation of multi-directional force, or the set critical condition for abandoning the wire cannot be adjusted, causing inconvenience in use
