Abstract
The invention provides a method for preventing a damping wire of a ground wire of a transmission line from breaking. According to the method provided by the invention, by utilizing a protecting device (3) consisting of two rectangular protective blocks which are arranged in a bilateral symmetry mode, corrosion destruction of various corrosive gases, ultraviolet rays, moral integrity rainwater and water steam above a stream of the outside on the ground wire (1) of the transmission line and the damping wire (3) are isolated, thus improving the corrosion resistance and breaking resistance of the damping wire of the ground wire of the transmission line, achieving the purpose of durability of the damping wire of the ground wire of the transmission line, and improving the corrosion resistance of the damping wire of the ground wire of the transmission line. With the adoption of the method, the corrosion resistance to metals of the damping wire of the ground wire of the transmission line is obvious, accidents of power failure in a large area due to grounding short circuit faults of the transmission line due to breaking of the damping wire of the ground wire are prevented, the grid power transmission and distribution safety production level is increased, and the method is suitable for protecting the damping wire of the ground wire of the transmission line.
Description
Technical field
The present invention relates to a kind of transmission line ground wire damping wire fracture method that prevents, belong to ultra-high-tension power transmission line operation maintenance maintenance equipment technology field.
Background technology
The effect of transmission line ground wire damping wire is to prevent the vibration of transmission line ground wire, it is requisite important component in the transmission and distribution network, prevent that in ultra-high-tension power transmission line operation maintenance maintenance equipment technology field the fracture of transmission line ground wire damping wire from being the important leverage of electric line safety in production, its safe operation is directly connected to the safety and stability of electrical network and the reliability that the user is powered.
And twine with wire at the general transmission line ground wire damping wire place of being connected and fixed, and exposes in atmosphere, is subject to the corrosion of various corrosive gass, ultraviolet ray, frost rainwater and top, river steam and ruptures, and causes the transmission line ground short circuit.Use the present invention will effectively prevent the corrosion of transmission line ground wire damping wire, thereby avoid because of transmission line ground wire damping wire seriously corroded, mechanical strength descends, cause fracture, and make transmission line ground short circuit fault, cause the generation of large area blackout, effectively ensure the transmission and distribution network safety in production.
Summary of the invention
The objective of the invention is,, ensure the safety of transmission line, the invention discloses a kind of transmission line ground wire damping wire fracture method that prevents in order to promote the anticorrosive anti-fracture performance of transmission line ground wire damping wire.
Technical scheme of the present invention is; utilize a kind of symmetrical structure and have the protective device of sealing ring all around; in order to isolate extraneous various corrosive gas, ultraviolet ray, frost rainwater and top, river steam corrosion failure to transmission line ground wire damping wire; promote the anticorrosive anti-fracture performance of transmission line ground wire damping wire, thereby reach the long-lived purpose of transmission line ground wire damping wire.
Protective device of the present invention be made of two symmetrical rectangle protection pieces, but rectangle is protected the seal groove of processing the semi-circular recesses of embedding ground wire, damping wire in the piece in advance and can embedding sealing strip.Ground wire, damping wire can be embedded in ground wire casing and the damping wire casing respectively during use; with the cross section is in the sealing strip of square type embeds around the protective cover in the seal groove; evenly tighten the fastening snap close of protective cover; protective device is tightly wrapped up the place that is connected and fixed of ground wire, damping wire; effectively isolate extraneous various corrosive gas, ultraviolet ray, frost rainwater and top, river steam to the corrosion failure of transmission line ground wire damping wire, promoted the anticorrosive anti-fracture performance of transmission line ground wire damping wire metal.Reduced the lightning fault trip-out rate of transmission line.
The invention has the beneficial effects as follows, do not adopt the ground wire damping wire of this guard method to compare with other, the transmission line ground wire damping wire fracture method protective device that the present invention forms has following characteristics: 1. to transmission line ground wire damping wire omnibearing protection, reduce the erosion to transmission line ground wire damping wire of ultraviolet ray and frost rainwater; 2. secure fixation transmission line ground wire and damping wire more; 3. installation method is simple, rapid.This method is simple and easy to do, protective device is installed rapidly.The present invention is obvious to the anticorrosive anti-fracture effect of transmission line ground wire and damping wire metal.Can effectively prevent the damping wire fracture and cause transmission line ground short circuit fault, the large area blackout of initiation improves electrical network power transmission and distribution safety in production level.Simultaneously, reduce the lightning fault tripping operation number of times of transmission line, reduced the negative effect that large-area power-cuts produces social each side.On the other hand, the protective device that the present invention forms is simple in structure, and it is easy and durable to select materials, and reliability is also very high.
The present invention is suitable for the protection to transmission line ground wire damping wire.

Embodiment
The specific embodiment of the present invention such as Fig. 2, shown in Figure 3.
The embodiment of the invention adopts transmission line ground wire and damping wire protective device that transmission line ground wire and damping wire are protected.Ground wire and damping wire protective device are made of two symmetrical rectangle protection pieces 3, rectangle protection piece 3 is processed by cast aluminium, the embedded semi-circular recesses of rectangle protection piece, the groove radius is identical with ground wire and damping wire external diameter, in the block protective cover 1 of rectangle up and down two ends along on be processed with seal groove; With the cross section is that the sealing ring 2 of square type embeds protective covers up and down in the inner surface seal groove of two ends; evenly tighten the fastening snap close of protective cover; with protective device tightly package clip fasten ground wire and damping wire; effectively isolate extraneous various corrosive gas, ultraviolet ray, frost rainwater and top, river steam ground wire and damping wire corrosion of metal have been destroyed, promoted the anticorrosive anti-fracture performance of ground wire and damping wire.Must be before ground wire and damping wire protective device are installed earlier to ground wire and damping wire external coating anticorrosive paint; after anticorrosive paint is done; ground wire and damping wire protective device are installed again; avoided of the oxide etch of the little air of retention, can protect ground wire and damping wire to avoid corrosion better ground wire and damping wire.
