Abstract
Provided is an overhead transmission line windage-yaw proofing insulation fixing device, relating to the field of power transmission lines and is characterized in that a fixing member (3) is fixed to a cross arm (1), an insulator (4) is fixed to the tail end of the fixing member (3) through a bolt (2), a suspension clamp (7) is fixed to the insulator (4) through a bolt A (5), and a lead (6) is fixed to the suspension clamp (7). The fixing device is simple in structure and convenient to install, windproofing upgrade reconstruction of a tower can be prevented, the cost is reduced, and the power transmission lines can be better controlled, the fault frequency can be reduced, and the safe and stable operation of the power transmission lines can be guaranteed.
Description
one, technical field
The present invention relates to transmission line field, particularly a kind of overhead transmission line wind-deviation insulating fixing device.
two, background technology
The current stability requirement for intelligent power network construction and system is more and more higher.The safe and stable operation improving transmission line is carrying out one of transmission line operation important process, it causes the ratio of transmission line barrier factors windage yaw discharge also in the middle of transmission line obstacle in recent years to climb up and up, show according to statistics, windage yaw discharge is topmost windburn fault type, especially 110kV and above ultra-high-tension power transmission line, windage yaw discharge accounts for 90% of windburn fault, and strong wind foreign matter accounts for 10%, and windage yaw discharge main manifestations is that wire discharges to shaft tower.According to investigations, the windage yaw discharge phenomenon of Xinjiang, the Northwest, Qinghai Area is more outstanding, the common tower of windage yaw discharge is " cat head shape ", " dry font ", generally occur in strain rod tower, in recent years straight line pole windage yaw discharge also obviously to increase, the general wind-deviation measure adopted is that strong wind section shaft tower carries out windproof upgrading at present, increase large scale shaft tower, but take this method, will expensive engineering cost be caused.
three, summary of the invention
A kind of overhead transmission line wind-deviation insulating fixing device is the invention provides for the problems referred to above, its structure is: cross-arm (1) is fixed with fixture (3), the end of fixture (3) is fixed with insulator (4) by bolt (2), insulator (4) is by bolt A(5) be fixed with suspension clamp (7), suspension clamp (7) is fixed with wire (6).
Beneficial effect of the present invention is: type structure is simple, easy for installation, does not need to carry out windproof upgrading to shaft tower, reduces costs, and can be good at controlling transmission line, reduces obstacle number of times, ensures the safe and stable operation of transmission line.
four, accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, cross-arm, 2, bolt, 3, fixture, 4, insulator, 5, bolt A, 6, wire, 7, suspension clamp.
five, embodiment
Embodiment 1, a kind of overhead transmission line wind-deviation insulating fixing device, its structure is: cross-arm (1) is fixed with fixture (3), the end of fixture (3) is fixed with insulator (4) by bolt (2), insulator (4) is by bolt A(5) be fixed with suspension clamp (7), suspension clamp (7) is fixed with wire (6).
Claims (1)
1. an overhead transmission line wind-deviation insulating fixing device, it is characterized in that: cross-arm (1) is fixed with fixture (3), the end of fixture (3) is fixed with insulator (4) by bolt (2), insulator (4) is by bolt A(5) be fixed with suspension clamp (7), suspension clamp (7) is fixed with wire (6).
