Abstract
The invention relates to an insulator string with a buffer, and belongs to the technical field of power transmission and distribution engineering. The insulator string is composed of an insulator string body 1 and a buffer, and is characterized in that the buffer is composed of a pull rod 2, a spring cylinder 3, bolts 4, a cylinder cover 6 and a compressed spring 8; the tip end of the pull rod 2 is provided with a hole; the root end of the pull rod 2 is provided with an end disk 7 and inserted into the spring cylinder 3, and the rod tip extends out from a center hole of the cylinder cover 6; the compressed spring 8 is clamped between the end disk 7 of the pull rod 2 and the cylinder cover 6; and the cylinder cover 6 is embedded into the opening end of the spring cylinder 3 and consolidated by a plurality of bolts 4. The insulator string is mounted on a cross arm of an iron tower through the buffer. When a wire generates sudden impact tension, the compressed spring 8 of the buffer is pressed and deformed, the impact force is absorbed, and the wire is prevented from being broken. The heavy ice and wild wind resisting ability of the wire is improved; the power transmission safety is improved; and power transmission accidents derived from wire breakage are reduced. The insulator string with the buffer is used for hanging a wire to a cross rod of a power transmission tower.
Description
Technical field
Power transmission and distribution project.
Background technology
The wire of transmission line of electricity, in snowy day accumulated snow Cheng Bing, be one from scratch, by thin to thick process, to wire
Load belongs to static load.Ice melting after snow, the wire at typically all insulator chain two ends have one end first to melt.It is a burst that ice sheet comes off
Process;Therefore, when the wire ice sheet of insulator chain one end comes off suddenly, the wire of the other end is just made to produce the prominent of tenesmus suddenly
Loading is carried.Spontaneous load belongs to dynamic load.Gravitational field endogenous cause of ill gravity produce Dynamic Amplification Factor be 2, i.e., ice melting when, wire tension
Most conference doubles, therefore ice melting easily breaks.The transmission line of electricity of existing transmission line of electricity, particularly heavy icing area needs to solve to resist
Heavy ice technology.
The content of the invention
Insulator chain with buffer technical problem to be solved is:Strengthen wire in running, opposing impact is opened
The ability of power.
Using technical scheme be:The sling point of insulator chain sets up a buffer.
Insulator chain with buffer (Fig. 1) is made up of insulator chain body 1 and buffer.Buffer is by pull bar 2, spring cylinder
3rd, bolt 4, cover 6, stage clip 8 are constituted.2 top end of pull bar has hole;Butt has end plate 7, inserts spring cylinder 3, and the bar tip is from 6 centre bore of cover
Stretch out.Stage clip 8 is accompanied between the end plate 7 and cover 6 of pull bar 2.Cover 6 is embedded in the mouth end of spring cylinder 3, is consolidated with several bolts 4.
During use, the tip hole of pull bar 2, by connection gold utensil, is connected with insulator chain body 1.The connecting plate 5 at 3 bottom of spring cylinder, leads to
Connection gold utensil is crossed, is connected with steel tower cross-arm.When connected wire produces impact snap tension, the pull bar 2 of buffer, pull bar is passed to
2 end plate 7 makes 8 compressive deformation of stage clip, absorbs impulsive force, can prevent from breaking wire.
The beneficial effect of the insulator chain with buffer is:1st, the impact snap tension of wire can be effectively absorbed, improvement is led
Line resists the ability of heavy ice and blast;2nd, improve transmission of electricity safety;3rd, reduce transmission of electricity accident derived from broken string.
