Distribution line pole two-direction load protective integrated device

Abstract

The present invention provides a distribution line pole two-direction load protective integrated device which is formed by a horizontal / line load control structure and a support fixed structure. The horizontal / line load control structure comprises a base whose cross section is provided with a trapezoidal groove in the middle. The trapezoidal groove is internally provided with a slider whose cross section surface is matched with the shape of the trapezoidal groove. The top surface of the slider is provided with a semicircular groove which is coaxial with the trapezoidal groove, one side of the semicircular groove is hinged to one end of a half ring through a hinge shaft, and the other end of the half ring is connected to the other side of the semicircular groove through a bolt. The front and back end faces of the base are provided baffle plates. The device is installed between a conductive wire and a porcelain cross arm, a traditional construction process is not affected, through installing the device, the external force protection of a distribution operation line pole in a line direction and a horizontal direction is realized at the same time, the pole fall and breakage in typhoon, icing and other natural disaster conditions can be effectively reduced, the line loss is reduced, and the repair efficiency is effectively improved.

Description

technical field [0001] The invention relates to an integrated device for two-way load protection of distribution network line poles. Background technique [0002] The distribution line refers to the line that sends power from the step-down substation to the distribution transformer or sends the power from the distribution substation to the power unit. The wires, poles, porcelain cross-arms and other units in the distribution network line are fixedly connected. When the external force on the line exceeds the bearing capacity of the pole, especially when it encounters natural disasters such as typhoon and icing, and accidents such as trees pressing the line, it is prone to accidents such as pole fall and pole collapse in the tension section. Cause serious loss of distribution lines and indirect huge economic loss. In addition, for the restoration of the line, the downturned and broken poles of the electric poles have increased the difficulty of emergency repairs, increased t...

AI Technical Summary

Problems solved by technology

The wires, poles, porcelain cross-arms and other units in the distribution network line are fixedly connected, and the poles are connected as a whole through the fixed connection of wires and porcelain cross-arms (or porcelain bottles). When the line encounters external forces exceeding the bearing capacity of the poles, especially when encountering natural disasters such as typhoons, ice cover, etc., as well as accidents such as trees pressing the line, accidents such as falling down and breaking the poles and falling accidents of the poles in the tension section are prone to occur. Cause serious loss of distribution lines and huge indirect economic losses
