Abstract
Provided is an air gap line type lightning arrester electrode structure, comprising an upper electrode and a lower electrode, wherein the lower electrode is in connection with a shroud ring which clamps and fix an original line of an electric transmission line. An original line is provided with a discharging gap lower electrode in order that electric arc can generate on the upper electrode and the lower electrode, avoiding burning or burnout of lines caused by electric arc generated in a discharging process; meanwhile the air gap line type lightning arrester electrode structure can endure electric arc burning more than once, is convenient to maintain and has low costs.
Description
Technical field
The utility model relates to a kind of air gap Transmission Line Arrestor electrode structure, mainly is arc damage wire problem when solving gap discharge.
Background technology
Transmission line subjects to the section of thunderbolt and adopts the air gap Transmission Line Arrestor as effective protection electrical equipment of line thunder protection, can improve line lightning resisting level, reduces tripping rate with lightning strike, uses in a large number on transmission line at present.The discharging gap structure of the air gap arrester that uses on the market consist of discharging gap top electrode and discharging gap bottom electrode, bottom electrode all replaces with the former wire of transmission line, the arc electrode that produces in discharge process is like this burnt easily even is blown wire, causes the loss of power accident.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of air gap Transmission Line Arrestor electrode structure for above-mentioned prior art present situation, both guaranteed by this structure that the electric arc that produces can not burn even blow wire in discharge process, and be convenient to again install.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this air gap Transmission Line Arrestor electrode structure, comprise top electrode, it is characterized in that fixedly mounting bottom electrode at the former wire of transmission line, make the electric arc that produces between the original from power on utmost point and the wire, change into the from power on utmost point and bottom electrode generation.Avoid like this electric arc burn that in discharge process, produces even blown wire.
Described bottom electrode can be connected on the bottom electrode shroud ring, and the bottom electrode shroud ring is clamped and fixing cord.And described bottom electrode and top electrode are cross and are staggered installation of.
Compared with prior art, the utility model has the advantage of: install the discharging gap bottom electrode additional at former wire, electric arc is produced between top electrode and bottom electrode, avoided the electric arc burn that in discharge process, produces even blown wire; Simultaneously, this structure can repeatedly stand the electric arc calcination, and updating maintenance is convenient, with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Please refer to shown in Figure 1, this air gap Transmission Line Arrestor electrode structure includes top electrode 2 and bottom electrode 3, wherein top electrode 2 is connected to the bottom of lightning arrester body 1, and bottom electrode 3 is connected with bottom electrode shroud ring 5, and bottom electrode shroud ring 5 is clamped and fixing cord 4.
This air gap Transmission Line Arrestor electrode structure makes the electric arc that produces between the original from power on utmost point 2 and the wire 4, changes into the from power on utmost point 2 and bottom electrode 3 generations.Avoid like this electric arc burn that in discharge process, produces even blown wire.And top electrode 2 and bottom electrode 3 right-angled intersections are installed, and it is minimum that the impact that variation causes on arcing distance of wind pendulum is dropped to, and greatly improves its discharge stability, avoid frequent discharge, misplace the bad phenomenon generations such as electric.
Claims (3)
1. air gap Transmission Line Arrestor electrode structure, comprise top electrode (2), it is characterized in that: at the former wire of transmission line (4) fixed installation bottom electrode, made originally the from power on electric arc of generation between the utmost point (2) and wire (4), and changed into from power on and produce between the utmost point and bottom electrode.
