Abstract
The utility model discloses a wire sheath used for the wire of an electric transmission line. The wire sheath is shaped as a circular tube, two ends of the wire sheath are provided with an outward flanging respectively, and the included angle between each flanging and the axis of the wire sheath in the length direction is 30 degrees. The wire sheath is provided with a slot, wherein the slot is parallel to the axis of the wire sheath in the length direction. The length of the wire sheath between the flangings at two ends is greater than the length of the bottom of a wire clamp which is matched with the wire by 10mm. The inner diameter of the wire sheath is equal to the outer diameter of the corresponding wire, and the outer diameter of wire sheath is greater than the inner diameter of the wire sheath by 10mm. The wire sheath of the utility model has the following advantages: the wire sheath of the utility model can be used to effectively prevent the aggravation of the abrasive damage of the wire caused by the loosening of a wire protection device; even the wire sheath loosening situation exists in the construction or running process, due to the existence of the inherent characteristic of the overall big plane of the wire sheath, the situation that the abrasion of the wire is aggravated which occurs in the case that the outer edge of the wire is cut by the edge of a conventional aluminium armour tape after the conventional aluminium armour tape looses will out occur.
Description
Technical field
The utility model belongs to the electric power transfer field, is specifically related to a kind of wire bushing for transmission line wire.
Background technology
The current power transmission line conductor is generally adopting aluminium strip to twine retaining part to form the form of protection by the line clamping device such as suspension clamp and position that stockbridge damper is installed, the plus load that namely uses aluminium strip to twine to utilize wire clamp behind the wire with wire with protect the line aluminium strip and compress to form protection.
Along with improving constantly of transmission line electric pressure; wire diameter and ampacity continue to increase; and the protectors such as carbon cloth of traditional aluminium armor tape and follow-up appearance adopt canoe when parcel can't accomplish and the fitting tightly of wire at the scene; thereby cause in running, often existing aluminium armor tape loosening; this can cause protecting line aluminium strip effective guardwire not only in running; can accelerate on the contrary the abrasive damage speed of wire, for hidden danger has been buried in the safe operation of transmission line.
The utility model content
Wire protector can't fit tightly with wire in the prior art in order to overcome, the defective of becoming flexible easily, and the utility model provides a kind of wire bushing for transmission line wire.
Concrete technical scheme of the present utility model is as follows:
A kind of wire bushing for transmission line wire is circular tube shaped, and two ends are provided with outside flange 2, and the angle between the axis of flange 2 and wire bushing 1 length direction is 30 °; Offer slot 3 on the wire bushing 1, slot 3 is parallel with the axis of wire bushing 1 length direction; The length that wire bushing 1 length between the two ends flange 2 equals wire clamp 5 bottoms of matching with wire 4 adds 10mm.
The internal diameter of described wire bushing 1 equals the external diameter of respective wire 4, and the internal diameter that the external diameter of wire bushing 1 equals wire bushing 1 adds 10mm.
The utility model has the advantage of:
(1) the utility model can effectively prevent from aggravating because of the loosening wire abrasive damage that causes of line protection device;
(2) even the utility model is loosening at work progress or existence in service, because the inherent characteristic on its whole large plane after loosening the situation that its edge cuts wire outer ring causes wire wearing and tearing aggravation does not occur thereby can not produce the conventional aluminum band yet.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of cross section of the present utility model.
Fig. 3 is scheme of installation of the present utility model.
Fig. 4 is use state diagram of the present utility model.
Sequence number among the upper figure: wire bushing 1, flange 2, slot 3, wire 4, suspension clamp 5.
The implementation way:
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of wire bushing for transmission line wire, described wire bushing 1 is circular tube shaped, and two ends are provided with outside flange 2, and the angle between the axis of flange 2 and wire bushing 1 length direction is 30 °.Offer slot 3 on the wire bushing 1, slot 3 is parallel with the axis of wire bushing 1 length direction.The length that wire bushing 1 length between the two ends flange 2 equals suspension clamp 5 bottoms of matching with wire 4 adds 10mm.
The internal diameter of wire bushing 1 equals the external diameter of respective wire 4, and the internal diameter that the external diameter of wire bushing 1 equals wire bushing 1 adds 10mm, sees Fig. 2.
Installation of the present utility model, using method are as follows:
The first step as shown in Figure 3, when constructing at the scene, is broken into two with one's hands by hand and is entangled wire 4 behind the wire bushing 1 and hold the position with adding of wire clamp;
Second step as shown in Figure 4, snaps in suspension clamp 5, is undertaken fasteningly by the bolt on the suspension clamp 5, gets final product so that wire bushing 1 fits tightly with wire 4 and suspension clamp 5.
In order to guarantee that wire bushing 1 can fit tightly with wire 4 in suspension clamp 5 clamping process, the opening of wire bushing 1 should be arranged straight up so that wire bushing can have enough deformation spaces when shrinking.
