Abstract
The utility model discloses a wire-break prevention device for an overhead conductor. The wire-break prevention device for the overhead conductor comprises the overhead conductor, a wire-break prevention stay wire, a pin insulator and a parallel groove clamp, wherein two ends of the wire-break prevention is fixed through the parallel groove clamp and the overhead conductor in a parallel mode. The wire-break prevention stay wire is fixedly connected with the pin insulator. The guide wire of the wire-break prevention stay wire is the same as that of the overhead conductor. A rope is arranged on the pin insulator of the original overhead conductor, and the rope and the overhead conductor are fixed together through the parallel groove clamp in a parallel mode, and the rope and the overhead conductor are fixed together in the pin insulator at the middle portion of the rope. Accordingly the tension which the bearing point of the original overhead conductor bears is divided into two, the rope and the overhead conductor each bear one half of the tension, relay beard in the stress point of the overhead conductor is effectively decreased, and wire breaking accidents are prevented, and thus security accidents such as fire and lighting stroke caused by the wire break are prevented, the certain hidden troubles for the life and property safety of people are removed. The wire-break prevention device for the overhead conductor is simple, practical and low in cost.
Description
Technical field
The utility model relates to the power line protection technical field, relates in particular to a kind of aerial condutor prevention break wire device.
Background technology
Find that according to investigation it 90 percent all is in 20 cm range of pin insulator two ends, to break that aerial condutor breaks.Within 20 centimetres at the pin insulator two ends is the maximum hard point of circuit, is the main position that the broken string accident takes place, in case the broken string accident takes place; Carry out wiring, thread-changing again; Not only constructional difficulties, cost are very high, and if broken string back find untimelyly, be easy to reproduce into electric shock accidents; Lives and properties to people cause great loss, and are very dangerous.
The utility model content
The purpose of the utility model provides a kind of aerial condutor prevention break wire device that can effectively prevent the aerial condutor broken string.
For the technical scheme that purpose adopted that realizes the utility model is: a kind of aerial condutor prevention break wire device; Comprise aerial condutor, anti-disconnected backguy, pin insulator and parallel groove clamp, said anti-disconnected backguy two ends are parallelly connected with said aerial condutor fixing through said parallel groove clamp.
Said anti-disconnected backguy is fixedly connected with affiliated pin insulator.
The lead of said anti-disconnected backguy employing and aerial condutor same model.
The utility model is provided with an anti-disconnected backguy at the pin insulator place of former aerial condutor; Be fixed together through the parallel groove clamp parallel connection, and aerial condutor be fixed on pin insulator with anti-disconnected backguy, can be divided into two the suffered pulling force of original aerial condutor hard point in anti-disconnected backguy middle part; Make anti-disconnected backguy and aerial condutor bear half the pulling force separately; Reduced the relay that stress point bore on the aerial condutor effectively, the generation of prevention broken string accident, thus also stopped because of security incidents such as fire that broken string is caused, electric shocks; Remove certain hidden danger for people's the security of the lives and property, the simple and practical cost of the utility model is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, a kind of aerial condutor prevention break wire device comprises aerial condutor 1, prevents disconnected backguy 3, pin insulator 4 and parallel groove clamp 2, and said anti-disconnected backguy 3 is through said parallel groove clamp 2 and said aerial condutor 1 parallelly connected fixing.Said anti-disconnected backguy 3 is tied up with affiliated pin insulator 4 and is connected.The lead with aerial condutor 1 same model is adopted in said anti-disconnected backguy 3.
The utility model is provided with an anti-disconnected backguy at the pin insulator place of former aerial condutor, said anti-disconnected backguy preferably with the lead of aerial condutor same model, can make lead fixed more firm like this, do not affect the appearance yet.Be fixed together through the parallel groove clamp parallel connection; And preventing that disconnected backguy middle part is fixed on pin insulator with aerial condutor with anti-disconnected backguy; Can be divided into two the suffered pulling force of original aerial condutor hard point, make anti-disconnected backguy and aerial condutor bear half the pulling force separately, reduce the relay that stress point bore on the aerial condutor effectively; The generation of prevention broken string accident; Thereby also stopped the security incidents such as fire, electric shock that caused because of broken string, for people's the security of the lives and property is removed certain hidden danger, the simple and practical cost of the utility model is low.
Claims (3)
1. an aerial condutor prevents break wire device, it is characterized in that: comprise aerial condutor, anti-disconnected backguy, pin insulator and parallel groove clamp, it is parallelly connected with said aerial condutor fixing that said parallel groove clamp is passed through at said anti-disconnected backguy two ends.
2. aerial condutor prevention break wire device as claimed in claim 1 is characterized in that: said anti-disconnected backguy is fixedly connected with said pin insulator.
