Transmission line lightning protection always is the important content of power department Thunder Protection, and lightning stroke trip fault affects the difficult problem that countries in the world power grid security powers.The impulse flashover that transmission line causes when there is thunderbolt, causes line insulator flashover, then produces very large power frequency continued flow, damages insulator string and gold utensil, causes circuit breaking accident.Traditional " blocking type " lightning protection mode (as erection lightning conducter, reduce pole tower ground resistance, reinforced insulation and install the modes such as coupling ground wire additional); due to its limitation; can not solve problem of lightning, therefore power department generally adopts and installs parallel connection gaps additional to realize route protection at transmission line at all.Specifically, the i.e. pair of metal electrodes (i.e. arcing horn electrode) in parallel at the insulator string of resistance to electric arc two ends, when overhead transmission line is struck by lightning, insulator string produces very high lightning overvoltage, but because the lightning impulse flashover voltage of parallel connection gaps is lower than the discharge voltage of insulator string, therefore first parallel connection gaps discharges; The power frequency arc continued is under electric power and thermal stress effect; by the discharge channel that parallel connection gaps is formed, be directed to arcing horn electrode tip, be fixed on the burning of arcing horn electrode tip; thus protection insulator avoids electric arc calcination, and then the safe operation of protection overhead transmission line.For pendency shaft tower, the ground side electrode of its parallel connection gaps is upper arcing horn electrode, and side of wire electrode is then lower arcing horn electrode; Usually, upper arcing horn electrode is fixed on the bowl head place of insulator string, and need to change a bowl head when changing, this mode wastes time and energy, inefficiency, adds the labour intensity of operating personnel simultaneously, extends the activity duration, increases use cost.
Therefore, in order to solve the problems of the technologies described above, just need a kind of upper arcing horn electrode buck plate, can upper arcing horn electrode be firmly arranged on insulator string ball-eye, reduce operation easier when changing, alleviate the labour intensity of operating personnel, shorten the activity duration, time saving and energy saving, improve operating efficiency, save use cost.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of upper arcing horn electrode buck plate, can upper arcing horn electrode be firmly arranged on insulator string ball-eye, reduce operation easier when changing, alleviate the labour intensity of operating personnel, shorten the activity duration, time saving and energy saving, improve operating efficiency, save use cost.
Upper arcing horn electrode buck plate of the present utility model, comprises buck plate body, and the middle part of described buck plate body is recessed to form the draw-in groove for being connected with ball-eye downwards, the connecting rod form-fit of described draw-in groove and ball-eye; Described buck plate body is also provided with the clamp being positioned at draw-in groove both sides; After described draw-in groove is fixedly connected with connecting rod, described clamp may be stuck in the link side of ball-eye to limit the rotary freedom of buck plate body along connecting rod axis.
Further, the cell wall thickness of described draw-in groove is not less than the thickness of buck plate body.
Further, the curved or rhombus of described draw-in groove.
Further, described clamp is cylinder or cone.
Further, described clamp and this body by integral forming of buck plate; Or described clamp is welded on buck plate body.
Further, the both sides of described buck plate body extend to be formed two pieces of symmetrical connecting plates for connecting upper arcing horn electrode along its length.
Further, described connecting plate width is 1.5-2.5 times of buck plate body width.
Further, connecting plate described in each is equipped with at least two connecting holes for being connected with upper arcing horn electrode replaceable formula.
The beneficial effects of the utility model: upper arcing horn electrode buck plate of the present utility model, during use, the body of rod of connecting rod embedded draw-in groove and be fixedly connected with, clamp is stuck in link side simultaneously, horizontal, the longitudinal direction of buck plate body and rotary freedom are all limited, to be firmly arranged on insulator string ball-eye by upper arcing horn electrode, avoid the fitness affecting upper and lower arcing horn because of improper movement; Arcing horn electrode can be replaced with separately when changing, or upper arcing horn electrode and ball-eye are together changed, reduce operation easier when changing, alleviate the labour intensity of operating personnel, shorten the activity duration, time saving and energy saving, improve operating efficiency, save use cost.
