At present join in marriage net live working in-process, during bypass operation especially, the fixed head of turning round of cable and live wire lug connection that mainly leans on cable end now, because the cable that live working used is comparatively heavy, it is poor to turn round the head fixed its steadiness by the cable alone, when changing (taking the place of) the power supply for many days in succession very much, if meet wind and rainy weather, its steadiness can reduce by the effect of wind pendulum cable head, and there is the leakage current to produce, higher risk has all been brought to operation personnel's personal safety and the operation safety of equipment. Therefore, it is necessary to develop a cable fixing device dedicated for bypass operation, so as to enhance the connection manner between the cable and the wire and improve the stability of the bypass cable and the safety during operation.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's is not enough, provides a cable fixing device for net live working is joined in marriage to reliable performance, has solved the problem of bypass cable poor stability at the suspension in-process, security when having improved bypass cable's steadiness and operation.
The technical scheme of the utility model is realized like this: a cable fixing device for distribution network live working comprises an insulating support column, wherein the insulating support column comprises a porcelain column and a plurality of porcelain skirts arranged on the outer wall of the porcelain column, one end of the insulating support column is provided with a hook part connected with a tower cross arm, and the other end of the insulating support column is provided with a cable fixing part connected with a cable; the cable fixing part comprises a wire clamping piece, U-shaped cable slots are symmetrically formed in two sides of the wire clamping piece, a fixing hole is formed in the middle of the wire clamping piece, and the cable fixing part is connected to the knob insulator in a threaded mode through a fixing bolt.
And a connecting stud is fixed between the insulating strut and the hook part, and the hook part is in threaded connection with the connecting stud.
The hook part comprises a U-shaped hook body, the top of the hook body is provided with a connecting screw hole, the middle of the hook body is provided with a clamping sheet, and the side wall of the hook body is provided with an adjusting screw for adjusting the clamping sheet.
The insulating support column allows the highest working voltage to be not lower than 11.5 kV.
The utility model provides an existing defect among the background art, have following beneficial effect:
a join in marriage cable fixing device for net live working, solved the problem of bypass cable poor stability at the suspension in-process, security when having improved bypass cable's steadiness and operation. The utility model discloses to make the connected mode of cable and wire turn round the head directly to be become two point suspension type bridges by original single-point, improved bypass cable's steadiness, increase insulating pillar simultaneously with increase creepage specific distance, prevent that leakage current from hindering the people to security when improving bypass cable's operation can be applicable to various different operation environments.
