Abstract
The invention provides a technical scheme of a special grounding wire for a power transmission line. In the technical scheme, a wire jointing clamp is fixed on an extension column through a base; the extension column and the base are fixed through a bolt; the extension column comprises a plurality of extension rods which are connected end to end; one end of each extension rod is provided with a threaded slot, and the other end of each extension rod is provided with a bolt matched with the threaded slot; the wire jointing clamp is a hook-shaped clamp body; and a hook-shaped end of the clamp body is provided with two spring clamping sheets. According to the scheme, a stable fulcrum can be provided to a grounding wire and the wire jointing clamp effectively, so that a worker is not influenced by wind force when hanging the grounding wire and can hang the grounding wire onto a lead smoothly, in addition, the problem that the grounding wire is difficult to hang when the lead deviates the lower part of a cross arm by a certain distance is solved favorably, not only is the efficiency of hanging the grounding wire by the worker increased, but also the safety of the worker is guaranteed effectively.
Description
Technical field
What the present invention relates to is a kind of electric power overhaul instrument, the special-purpose earth connection of especially a kind of transmission line.
Background technology
In the prior art, technique known is in the high voltage power transmission industry, and the necessary ready-made safety measure when installing earth connection is line maintenance and examination is the important means that guarantees job site line work personal security.Use special-purpose insulation rope when at present, disconnecting ground wire to the extension of the power circuit more than the 220KV.With the insulation rope earth connection of slinging, the weight of swing and earth connection self of utilizing the insulation rope with ground wire hitching to lead.The method of the existing above circuit hanging earthing conductor of 220KV level: the people stands on the cross-arm; By hanging earlier earth terminal, the order of hanging lead more earlier is suspended to the iron tower side with earth terminal, uses the special-purpose insulation rope earth connection of slinging then; Utilize the earth connection own wt downward, earth connection is hung on the lead.Yet the method has a lot of shortcomings, and for example as staff during in the suspension of the interior angle of angle tower, lead deflects away from cross-arm one segment distance at cross-arm below tiltedly, and just be difficult to suspension this moment, uses the method need hang for a long time; When the suspension earth connection, having strong wind or bad weather to influence, because the softness of insulation rope, earth connection can be swung with the wind, also is difficult to earth connection is suspended on the lead, has caused the efficient of hanging earthing conductor lower, and this is the existing in prior technology weak point.
Summary of the invention
The object of the invention; Be exactly not enough to existing in prior technology, and the technical scheme of the special-purpose earth connection of a kind of transmission line is provided, this scheme is employed in and on the binding clip that connects earth connection extension rod is set; Can be effectively a stable fulcrum be provided for earth connection and binding clip; Make the staff when the suspension earth connection, not receive the influence of wind-force, successfully earth connection is suspended on the lead, and can solve when lead deflects away from cross-arm below one segment distance; Earth connection suspension situation of difficult can either improve the safety that efficient that the staff hangs earth connection can guarantee the staff again effectively.
This programme is realized through following technical measures: the special-purpose earth connection of a kind of transmission line, comprise the binding clip that is connected with earth connection, and it is characterized in that: binding clip is fixed on the extending column through base; Extending column and base are through bolt, and extending column is that earth connection and binding clip provide a stable fulcrum, and the staff can take extending column that earth connection is suspended on the lead by hand.
Further preferred as to this programme: extending column comprises the extension rod that a plurality of first places link to each other, and a plurality of extension rods interconnect, and can satisfy lead and cross-arm hang earth connection when different distance needs; One end of extension rod is provided with thread groove, is provided with the bolt with the thread groove coupling at the other end of extension rod, is connected with the thread groove of another extension rod through the bolt on the extension rod two extension rods are linked together from beginning to end.
Further preferred as to this programme: binding clip is hook-shaped clamp, makes things convenient for binding clip to be hooked on the lead.
Further preferred as to this programme: the hook-shaped end of clamp is provided with two spring cards, two spring leafs each other near, between two spring leafs, leave poroid space; When the suspension earth connection, lead is pressed into the poroid space between the two fast spring leafs, can guarantee firm the hanging on the lead of binding clip, prevent owing to rocking of lead caused coming off of binding clip.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because binding clip is fixed on the extending column through base in this scheme; Extending column and base are through bolt, and extending column is that earth connection and binding clip provide a stable fulcrum, and the staff can take extending column that earth connection is suspended on the lead by hand; Extending column comprises the extension rod that a plurality of first places link to each other, and a plurality of extension rods interconnect, and can satisfy the needs of lead and cross-arm suspension earth connection when different distance; One end of extension rod is provided with thread groove, is provided with the bolt with the thread groove coupling at the other end of extension rod, is connected with the thread groove of another extension rod through the bolt on the extension rod two extension rods are linked together from beginning to end; Binding clip is hook-shaped clamp, makes things convenient for binding clip to be hooked on the lead; The hook-shaped end of clamp is provided with two spring cards, two spring leafs each other near, between two spring leafs, leave poroid space; When the suspension earth connection, lead is pressed into the poroid space between the two fast spring leafs, can guarantee firm the hanging on the lead of binding clip, prevent owing to rocking of lead caused coming off of binding clip.
This shows, the present invention compared with prior art, in suspension during earth connection; The staff can be more quick; Tackling various be difficult for easily hangs over the difficult problem on the lead with earth connection, has substantive distinguishing features and progress, and the beneficial effect of its enforcement also is conspicuous.
