Embodiment 1

[0021] The invention is a clamp device for ground wire ends with adjustable gear distance, and the model is DXT-1. Such as figure 1 and figure 2 As shown, this device considers factors such as strength, flexibility, electrical conductivity, heat resistance, etc., comprehensively considers the use of copper-magnesium-aluminum materials as materials, and uses adjustable gear holes to fix overhead wires according to the diameter of overhead single wires and multiple wires. The wire diameter is adjustable, that is, this device solves the gap adjustment problem that occurs during the installation of various wire diameters overhead conductors and ground wires. According to the characteristics of the installation location and other factors, different styles of "interlocking" devices are designed. In this device, the combination of the upper buckle with the matching size of the wire diameter, the bilateral concave support or the single side concave support, the lower buckle and the...

Embodiment 2

[0027] Such as image 3 and Figure 4 In the shown, the model of the grounding wire head fixture device with adjustable gear distance of the present invention is DXT-2 type, wherein said concave support is a single-side concave support 11, and at this time, the upper buckle 4 is a single-side concave support. An "L" shape structure in which the pillars 11 coincide. Others are identical with embodiment 1.

[0028] The device is structurally divided into two parts due to its function, that is, the fixed wire part and the suspended ground wire part. The fixed wire part consists of: M8 screw 1, upper nut 2, upper gasket 3, upper buckle 4, unilateral concave pillar 11, adjustable gear hole 12, lower nut 10, lower gasket 9, lower buckle And the hook plate 8 thereof. Suspension ground wire part is made up of: hang ground wire slot 13. Wherein the adjustable gear function is realized by the upper buckle 4, the bilateral concave pillar 5, the adjustable gear hole 12, the lower buc...

Abstract

The invention relates to the technical field of a span adjustable grounding wire head clamp device. The device is characterized in that an upper retaining ring, a concave pillar and a lower retaining ring and a wire hanging plate thereof are connected by screws; and an adjustable retaining hole and a ground wire hanging groove are also arranged at the bottom of the lower retaining ring and the wire hanging plate thereof. The device has the following beneficial effects that the problem of installation of grounding wires of overhead single conductors with current-carrying capacities being above 879A and wire diameter areas being above 400mm<2> and overhead composite conductors with current-carrying capacities being above 1620A and wire diameter areas being above 400mm<2>*2 and the problem that the grounding wires are difficult to install in the places needing installation of the grounding wires due to various reasons are solved; and the device meets the requirements of electrical conductivity and heat resistance, has simple structure and can not only appropriately adjust the span to meet the installation requirement according to the overhead wire diameters on the site but also be suitable for various grounding wire conductor terminal joints.

Description

technical field [0001] The invention relates to the technical field of a grounding wire end clamp device with adjustable gear distance. It is a DXT type series, suitable for installation with an ampacity above 879A and a wire diameter area of ​​400mm. 2 (T=25°C) overhead single conductors with a carrying capacity above 1758A and a wire diameter area of ​​400mm 2 ×2 (T=25℃) above the ground wire terminal joint of the overhead multi-conductor, or the conductor terminal joint where it is difficult to install the ground wire due to various reasons. Background technique [0002] At present, the existing substation grounding wire wire end fixture head can only be installed at the current carrying capacity below 879A, and the wire diameter area is 400mm. 2 The following overhead single conductors and the current carrying capacity are below 1620A, and the wire diameter area is 400mm 2 On overhead multiple conductors below ×2, for overhead single conductors or multiple conductors s...
