Abstract

A V-shaped string for prevention of wind deflection comprises a composite insulator. A left insulator string and a right insulator string are fixed on two sides of the composite insulator respectively and used for preventing the wind deflection. The upper end of the left insulator string and the upper end of the right insulator string are respectively fixed with an electric pole or a cross arm of a power transmission tower. The left insulator string and the right insulator string are of a V-shaped structure. The left insulator string, the composite insulator and the right insulator string are located on the same plane. The V-shaped string for the prevention of the wind deflection has the advantages that the two insulator strings are fixedly arranged on the two sides of the composite insulator, the two insulator strings form the V-shaped structure, and therefore the wind deflection is effectively prevented from happening to the composite insulator at the time of wind blowing, the wind deflection resisting performance of the composite insulator is greatly improved, the failure rate of a power transmission line is reduced, and safety and stability of power transmission equipment are guaranteed.

Description

Anti-windage yaw V-type string

Technical field

The utility model relates to a kind of anti-windage yaw V-type string.

Background technology

The windage yaw fault when running into strong wind, the insulator in the transmission line takes place easily, can influence the stable operation of electrical network, especially in recent years on transmission line, adopt composite insulators as main suspenders in a large number, though this class composite insulator has multiple advantage, but the type insulator weight is lighter, it is substantially weaker than the porcelain insulating substring in anti-windage yaw effect, its windage yaw phenomenon is more general and serious when therefore meeting strong wind, particularly on middle circuitry phase because its single hang, windage yaw is especially serious, and the safety and stability of transmission line has been constituted very big hidden danger.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of anti-windage yaw V-type string.

The technical solution adopted in the utility model is: a kind of anti-windage yaw V-type string, comprise composite insulator, the both sides that it is characterized in that described composite insulator fixedly are useful on left insulator string and the right insulator string that prevents windage yaw respectively, the upper end of described left insulator string and right insulator string is fixed with the cross-arm of electric pole or electric power pylon respectively, the two V-shaped structure, and left insulator string, composite insulator and right insulator string three are in one plane.

Described a kind of anti-windage yaw V-type string, it is characterized in that fixedly there is parallel link plate described composite insulator bottom by suspension clamp, both sides in the both sides of parallel link plate fixedly have left fixed head and right fixed head respectively, described left fixed head is fixedlyed connected with the lower end of left insulator string through left wire clamp, and described right fixed head is fixedlyed connected with the lower end of right insulator string through right wire clamp.

The beneficial effects of the utility model are: by fixedly installing two insulator strings in compound inslation substring both sides, and two insulator strings constitute the V-shape structure, composite insulator generation windage yaw situation when preventing from blowing effectively, improve its wind resistance bias energy greatly, reduce the failure rate of transmission line, guaranteed the safety and stability of transmission facility.

Description of drawings

Fig. 2 is a left side/right fixed head master TV structure schematic diagram;

Fig. 3 is the left view of Fig. 2.

Among the figure, 1-composite insulator, 2-suspension clamp, the parallel link plate of 3-, 4-pin, 5-nut, 6-left side fixed head, 7-left side wire clamp, 8-left side insulator string, the right fixed head of 9-, the right wire clamp of 10-, the right insulator string of 11-.

Embodiment

As shown in Figure 1, composite insulator 1 is suspended on bar/tower cross-arm or other horizontal member, fixedlys connected with suspension clamp 2 in its underpart, and the lower end of suspension clamp 2 connects parallel link plate 3, at parallel link plate 3 pin 4 and nut 5 is arranged.The shape of left side fixed head 6 and right fixed head 9 is shown in Fig. 2-3, its upper end tilts, and the lower end is vertical, and it is vertically held a circular hole that is complementary with pin 4 and nut 5 sizes, be used for parallel link plate 3 between connection, its beveled end has with left wire clamp 7 and right wire clamp 10 wants the fixing hole that mates.Left side fixed head 6 is fastened on parallel link plate 3 both sides with right fixed head 9 by pin 4 and nut 5, left side insulator string 8 hangs on composite insulator 1 left side, and be connected with left fixed head 6 by left wire clamp 7, right insulator string 11 hangs on composite insulator 1 right side, and is connected with right fixed head 9 by right wire clamp 10.Left side insulator string 8 is fixed on the same member with upper end and the composite insulator 1 of right insulator string 11, and places composite insulator both sides, three to be positioned on the same plane, and two insulator strings form a V-shape structure.

When running into strong wind, because its overall structure is V-type, so structure is more firm, is difficult for rocking, and that guarantees to transmit electricity is safe and reliable.
