Embodiment 1

[0039] refer to Figure 1-6 and 8, including a support base 1, a connection assembly 2, a telescopic tensile assembly 3, a fixed assembly 4 and a support pendant 5, the support base 1 is fixedly connected to the high-voltage line tower, and the two ends are respectively connected with a telescopic tensile assembly through the connection assembly 2 3. The other end of the telescopic tensile component 3 is fixedly connected with a fixed component 4, and the support pendant 5 is fixedly installed on the bottom of the support seat 1;

[0040] The two fixing components 4 respectively fix the high-voltage wires, and the high-voltage wires pass through the support hanger 5 , and the high-voltage wires between the fixation components 4 and the support hanger 5 are reserved for expansion and contraction.

[0041] The support base 1 includes a base plate 101, a mounting plate 102, a longitudinal plate 103 and a reinforcement plate 104. The middle part of the base plate 101 is fixedly pr...

Embodiment 2

[0053] refer to Figure 7 In this embodiment, the structural design of the support base 1, the connecting assembly 2, the telescopic tensile assembly 3 and the support pendant 5 is the same as that of the first embodiment, except that the structure of the fixing assembly 4 is different. In this embodiment, the fixing assembly 4 Including U-shaped pendant 2 405 and self-locking buckle 406, one end of U-shaped pendant 2 405 is rotationally connected with fixed block 301 at one end of telescopic tensile assembly 3 through a rotating pin, and one side of self-locking buckle 406 is provided with an opening, And the opening is installed with a limit rod 407 by the spring rotating shaft, and a limiting structure is arranged between the limit rod 407 and the opening. A locking ring 409 is installed.

[0054] In this embodiment, the structure of the fixing assembly 4 is simplified in design while ensuring the connection strength, and the operation method is simple. Open the limit leve...

Embodiment 3

[0056] refer to Figure 9 In this embodiment, the structural design of the support base 1, the connecting assembly 2, the telescopic tensile assembly 3 and the fixing assembly 4 is the same as that of the first or second embodiment, except that the structure of the support pendant 5 is different. In this embodiment The support pendant 5 includes a rotating disk 504, a U-shaped base 505 fixedly arranged at the center of the rotating disk 504, a limit rod 506 mounted on the U-shaped base 505 for rotation at one end, and a fixed ring 502 installed at the other end of the limit rod 506 At least three sets of support springs 507 are equidistantly connected to the side walls of the limit rod 506 , and the other ends of the support springs 507 are fixedly connected to the rotating disk 504 .

[0057] In this embodiment, the limit rod 506 supporting the pendant 5 can rotate slightly in the horizontal plane and in the longitudinal plane through the rotating disk 504 and the U-shaped ba...

Abstract

The invention discloses an anti-pulling high-voltage line connection fitting, relating to the field of electric power fittings. The fitting comprises a supporting base, connecting assemblies, telescopic tensile assemblies, fixing assemblies and a supporting hanging piece, the supporting base is fixedly connected to a high-voltage line tower, the two ends of the supporting base are connected with the telescopic tensile assemblies through the connecting assemblies respectively, the other end of each telescopic tensile assembly is fixedly connected with the corresponding fixing assembly, and thesupporting hanging piece is fixedly installed at the bottom of the supporting base; the two fixing assemblies fix a high-voltage line respectively, the high-voltage line penetrates through the supporting hanging piece, and the high-voltage line between the fixing assemblies and the supporting hanging piece is reserved with the expansion amount. The connection and supporting strength of the power cable is high enough, the anti-pulling capacity of the power cable is improved, meanwhile, a monitoring system can detect whether the pulling degree is safe or not in real time, know the pulling degreein advance and take protection measures in advance, the later maintenance cost is greatly reduced, the probability of power failures is reduced, and the fitting is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of electric power fittings, in particular to a pull-resistant high-voltage line connecting fitting. Background technique [0002] Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection. Iron or aluminum metal accessories widely used in transmission lines are collectively referred to as fittings. There are many types of fittings with different uses, for example, various clamps for installing wires, various hanging rings for forming insulator strings, various crimping tubes and repair tubes for connecting wires, and various types of spacers for splitting wires In addition, there are various types of wire fittings used for poles and towers, as well as the size of the protective wires, which must cooperate with each other. [0003] When installing high-voltage lines, it is often necessary to set up a hig...
