A wire tightening device for high-voltage transmission and transformation lines

Abstract

The invention relates to the technical field of wire tightening, and discloses a wire-tightening device for high-voltage transformation and distribution lines. The device comprises a fixing ring arranged at the external part of a wire pole in a sleeved manner and fixedly connected with the wire pole, the top of the fixing ring is fixedly connected with a photoelectric component, the right side ofthe bottom of the photoelectric component is fixedly connected with an electric control box, the left side and the right side of the fixing ring are both fixedly connected with side plates, the tops of the side plates are fixedly connected with installation pipes, one sides of the tops, close to the fixing ring, of the side plates are provided with fixed pulleys, and the backside of the fixing ring is fixedly connected with an installation plate. According to the wire-tightening device for the high-voltage transformation and distribution lines, cables can be fixed more conveniently, the security and the reliability are better, wire-moving accidents can be effectively avoided, the distance between the cables and the ground is guaranteed, the generation of security accidents caused by bending and falling of the cables is avoided, the fracture of the cables due to over tightness can also be avoided, and the cables and the power transmission operation can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of wire fastening, in particular to a wire tightening device for high-voltage transmission and transformation lines. Background technique [0002] With the progress of society and the acceleration of economic construction, power customers have higher and higher requirements for high-quality and reliable power supply provided by the power sector. Live working maintenance can not only provide users with continuous and uninterrupted power supply, but also improve the power supply reliability of the power grid. At present, in my country, the replacement of 110kV-220kV tensile double-string composite insulators (one string) is mainly carried out by means of equipotential operation. In addition, according to the calculations of the State Grid Corporation of China, if a high-voltage line is used to transmit electricity of the same power, it can save 60% of land resources compared with a 500 kV high-voltage line. ...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a wire tightening device for high-voltage transmission and transformation lines, which has the advantages of higher safety and can adapt to the tightening work of high-voltage wires under different temperatures and different weathers, and solves the problem of 1 1. The weight of the aluminum alloy ring chain tensioner is too large, which increases the labor intensity of workers working at heights. At the same time, the safety and reliability are poor, and even lead to line accidents; 2. The high-voltage line will be heated and elongated in the case of high temperature in summer, resulting in two utility poles The high-voltage line between them will bend downward, reducing the distance between the high-voltage line and the ground, which will cause harm to pedestrians or vehicles passing under the high-voltage line; 3. The high-voltage line will be shortened when the temperature is low in winter, resulting in If the temperature is low, the shortening of the high-voltage line may cause the high-voltage line to break, causing the power supply to be affected; Broken, causing power supply damage
