Problems solved by technology

These insulators will fail to varying degrees after long-term service in various environments of the power grid, leading to failure accidents.
Moreover, in strong earthquakes and strong winds, the violent movement of wires and insulators is also prone to damage to insulators.
In addition, during the long-term service of various insulators, it is inevitable to bear various forms of vibration and shock loads generated by nature and wires, resulting in fatigue failure

Embodiment

[0015] A kind of threading type cable fixing device of the present invention, during specific implementation, such as figure 1 As shown, it includes a support tube 1, an insulating tube 2, a clip 5, a compression bolt 4, a U-shaped card 6 and other components. The supporting tube 1 is the supporting body of the whole device, and is required to be made of a material with high strength and good corrosion resistance. For example, it can be made of porcelain materials with good crack resistance, or stainless steel with good strength and corrosion resistance. The support tube 1 is provided with an insulating tube 2, which can be pressed into the support tube 1 by molding or inlaid process. The insulating tube 2 is provided with bell mouth 3 arc flanging, one is to avoid scratching the cable 10, and the other is to wrap the support tube 1 through the bell mouth 3 arc flanging of the insulating tube 2 to prevent the cable 10 from contacting the support tube 1. In order to prevent r...

Abstract

The invention discloses a threading cable fixing device, which comprises a supporting tube (1). An insulating tube (2) is arranged in the supporting tube (1), and a clamping piece (5) is arranged in the insulating tube (2); the clamping piece (5) is rotatably connected with a compression bolt (4) which penetrates through the supporting tube (1) and the insulating tube (2); and the supporting tube(1) is fixedly connected with a tower (7) through a U-shaped clamp (6). The device is simple in structure; through the U-shaped clamp structure, the threading cable fixing device is directly fixed onthe electric tower in a bearing manner, a traditional suspension insulator fixing mode is replaced, brittle failure of the insulator caused by electrical failure, mechanical failure, product defects,windage yaw, bird damage, poor grounding, mountain fire, external force damage, improper construction and the like of the traditional insulator is eliminated, and line breaking due to icing and stringbreaking and falling to the ground of an insulator string and breakage of the post insulator are avoided, the capability of a power transmission network in coping with severe weather is improved, andthe loss caused by power failure is reduced.

Description

technical field [0001] The invention relates to a threading type cable fixing device, which belongs to the technical field of electrical machinery and equipment manufacturing. Background technique [0002] Porcelain, glass and composite insulators are widely used in power transmission and transformation projects. After long-term service in various environments of the power grid, these insulators will fail to varying degrees and lead to failure accidents. Moreover, in strong earthquakes and strong winds, the violent movement of wires and insulators is also prone to damage to insulators. In addition, during the long-term service of various insulators, it is inevitable to bear various forms of vibration and shock loads generated by nature and wires, resulting in fatigue failure. In the sampling test of the insulators in operation, it is shown that the proportion of the mechanical tensile failure load value lower than the rated value accounts for 16.7% of the total number of s...
