Problems solved by technology
[0002] In the UHV DC transmission project, the equipment is connected with split wires. When the wires are too long, in order to improve the stress of the equipment terminals, a post insulator will be added between the two equipments, and then the flexible wires will be used to support the fittings. The stress situation of terminal equipment terminals, the existing soft wire support fittings are to support two wire spacers on the bottom plate with bolts and pillars. The parts of this kind of fittings are connected or welded together by bolts, which has a complex structure and is inconvenient to assemble. , and the strength is low, and the fittings are prone to damage when encountering extreme weather or earthquakes and other extreme conditions, which will affect the reliable operation of the power grid

Embodiment Construction
[0020] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] Specific embodiments of the wire supporting hardware of the present invention, such as figure 1 As shown, in this embodiment, four split wires need to be supported by wire support fittings. The wire support fittings include a fixed base 2, an annular support frame 1 and a wire clamp block 3 arranged on the outside of the ring support frame 1. The wire clamp block 3 and The split wires are clamped and fixed between the ring support frames 1, and the fixed base 2 and the ring support frame 1 are integrally formed by casting to simplify the assembly process and enhance the structural strength of the wire support hardware.
[0022] Specific as Figure 1-Figure 3 As shown, in the present embodiment, the annular support frame 1 is a regular polygon ring frame, and the wire clamp block 3 is installed on the edge of the regular polygon ring frame, and th...

The invention relates to a wire supporting hardware. The wire support hardware includes a fixed base, an annular support frame and wire clamp blocks arranged in groups, and the fixed base is used to be fixedly connected to the insulating support; the ring support frame is integrally arranged on the fixed base; each group of wire clamp blocks is provided with More than two wire clamping blocks are arranged around the axis of the ring-shaped support frame. The wire clamping blocks are fixedly connected to the support frame through threaded connectors. There is formed between the wire clamping blocks and the ring-shaped support frame for the wires to pass through along the ring-shaped support frame. The threading channel through which the axial direction passes through, the wire can be clamped and fixed by the wire clamp block when the threaded connection is tightened. In the wire support fittings of the present invention, the ring-shaped support frame is integrally arranged on the fixed base, and there is no need to fix each component by bolts, the structure is simple, and the assembly is convenient; and the integrally arranged fixed base and the ring-shaped support frame have higher overall strength , less prone to damage, improving reliability.
