A flexible fixing clamp device for preventing wind and sand from spreading on the conductive belt of an isolating switch

Abstract

The present invention discloses an upper clamping plate, an inner clamping plate and a lower clamping plate; the inner clamping plate is disposed transversely between the conductive layer and the protective sheet of the conductive belt, the upper clamping plate is disposed transversely above the protective sheet, and is fixedly connected to the inner clamping plate to clamp the protective sheet; the lower clamping plate is disposed transversely below the conductive layer, and the opposite surfaces of the lower clamping plate and the inner clamping plate enclose a clamping cavity of the conductive layer. The protective sheet is clamped by the upper clamping plate and the inner clamping plate to ensure that the fixing clamp device and the conductive belt remain relatively fixed so that the fixing clamp device does not slide along the conductive belt, and the conductive layer is fixed in the clamping cavity, which limits the lateral sliding space of the conductive sheet of the conductive layer, so that the stacked conductive sheets will not be separated in layers under the action of strong winds or sandstorms, thereby ensuring the reliable operation of the disconnector. The present invention uses a high-voltage disconnector to fix the conductive belt.

Description

Technical Field

[0001] The invention relates to high-voltage switch technology, and in particular to a flexible fixing clamp device for preventing wind and sand from spreading out of a conductive belt of an isolating switch. Specifically, the invention relates to a flexible fixing clamp device for preventing conductive layers from spreading out and tearing out of a conductive belt suitable for a high-voltage isolating switch under outdoor strong wind and sand conditions. Background Art

[0002] With the development of power grid and transmission projects, more and more transmission projects are entering areas with harsh natural environments, including windy and sandy areas; this puts higher demands on the environmental adaptability of disconnectors.

[0003] The flexible lamellar conductive strip 400 of the moving part of the isolating switch, the conductive strip 400 is as Figure 1 As shown, it includes a conductive layer 410 and a protective sheet 420 arranged on the upper layer of the conductive layer 410. The conductive layer 410 generally includes multiple layers of copper or aluminum conductive sheets stacked together, and has the characteristics of reliable conductivity and flexible bending movement. However, under strong wind and sandstorm conditions, the stacked conductive sheets can be easily blown apart by the strong wind and sandstorms, so that the conductive layer 410 is gradually torn apart by the wind, which seriously affects the reliable operation of the disconnector. Therefore, a solution is needed to prevent the conductive layer 410 from being torn apart by the wind. Summary of the invention

[0004] The object of the present invention is to provide a flexible fixing clamp device for preventing wind and sand from spreading of a conductive belt of an isolating switch, so as to solve the problem that the conductive layer is easily torn by strong wind.

[0005] The technical solution adopted by the present invention is: comprising an upper clamping plate, an inner clamping plate and a lower clamping plate;

[0006] The inner clamping plate is disposed transversely between the conductive layer of the conductive strip and the protective sheet, and the upper clamping plate is disposed transversely above the protective sheet and is fixedly connected to the inner clamping plate to clamp the protective sheet;

[0007] The lower clamping plate is arranged horizontally below the conductive layer, and the opposite surfaces of the lower clamping plate and the inner clamping plate enclose a clamping cavity for the conductive layer.

[0008] Further optimized, the height of the clamping cavity is greater than the thickness of the clamped conductive layer.

[0009] Further optimization, the lower clamping plate is a U-shaped plate, and both ends are connected by bolts and the upper clamping plate,

[0010] The inner splints are fixedly connected together.

[0011] The beneficial effects of the present invention are as follows: the protective sheet is clamped by the upper clamping plate and the inner clamping plate to ensure that the fixing clamp device and the conductive belt remain relatively fixed so that it will not slide along the conductive belt, and the conductive layer is fixed in the clamping cavity, thereby limiting the lateral sliding space of the conductive sheet of the conductive layer, so that the stacked conductive sheets will not be layered and dispersed under the action of strong winds or sand, thereby ensuring the reliable operation of the disconnector; at the same time, because the height of the clamping cavity is greater than the thickness of the conductive layer, the stacked conductive sheets are still in a relaxed state, which does not affect the free folding movement of the conductive layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0013] Figure 1 It is a schematic diagram of the structure of the conductive strip;

[0014] Figure 2 It is the overall installation diagram of the conductive belt anti-sand dispersion flexible fixing clamp device;

[0015] Figure 3 It is a cross-sectional view of a flexible fixing clamp device for preventing wind and sand dispersion of a conductive belt. DETAILED DESCRIPTION

[0016] like Figure 2 and Figure 3 The illustrated isolating switch conductive belt anti-sand dispersion flexible fixing clamp device comprises an upper clamping plate 100, an inner clamping plate 200 and a lower clamping plate 300;

[0017] The inner clamping plate 200 is disposed transversely between the conductive layer 410 of the conductive belt 400 and the protective sheet 420, and the upper clamping plate 100 is disposed transversely above the protective sheet 420 and is fixedly connected to the inner clamping plate 200 to clamp the protective sheet 420;

[0018] The lower clamping plate 300 is disposed horizontally below the conductive layer 410 . The opposite surfaces of the lower clamping plate 300 and the inner clamping plate 200 enclose a clamping cavity for the conductive layer 410 . The height of the clamping cavity is greater than the thickness of the conductive layer 410 .

[0019] The protective sheet 420 is clamped by the upper clamping plate 100 and the inner clamping plate 200 to ensure that the fixing clamp device and the conductive belt 400 remain relatively fixed so that it will not slide along the conductive belt 400, and the conductive layer 410 is fixed in the clamping cavity, limiting the lateral sliding space of the conductive sheet of the conductive layer 410, so that the stacked conductive sheets will not be layered and dispersed even under the influence of strong winds or sand, thereby ensuring the reliable operation of the disconnector.

[0020] At the same time, since the height of the clamping cavity is greater than the thickness of the conductive layer 410 , the stacked conductive sheets are still in a relaxed state, which does not affect the free folding movement of the conductive layer 410 .

[0021] Furthermore, the lower clamping plate 300 is a U-shaped plate, and both ends are fixedly connected to the upper clamping plate 100 and the inner clamping plate 200 by bolts 500. During the installation process, the lower clamping plate 300 is covered on the conductive layer 410 and aligned with the mounting holes of the upper clamping plate 100 and the inner clamping plate 200, and fixedly connected together by bolts 500.

[0022] The lower clamping plate 300 is designed as a U-shaped plate mainly to enclose a clamping cavity for clamping the conductive layer 410 with the inner clamping plate 200. Other forms of clamping cavity structures are also within the scope of this protection, such as designing the inner clamping plate 200 as an inverted U-shaped clamping plate.

[0023] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
