Abstract
The utility model consists of a triangle insulated support rack, a line card and an aerial insulated conductive wire; wherein the support rack is approximately a triangle, and an embedded line groove is respectively arranged on the top of three corners, the two sides of the groove are provided with a line card and a lock fastening hole, each of the embedded line groove and the line card has a semi-circle slot and the two semi-circle slots just form a round slot, the inner diameter of which is matched with the outer diameter of the aerial insulated conductive wire that is a steel-core aluminum strand. The aluminum strand enwraps the inner insulating layer, and metal shielding wire is arranged outside the inner insulating layer, and the most outer layer is an insulating protection layer. The three conducting wires are embedded into the round slot that is enclosed by the triangle insulated support rack and the line card; and is spanned on an electric pole. The three wires are positioned at regular distance but not far from each other. Little room is only occupied.
Description
The utility model relates to a kind of insulated overhead line assembly.
Along with developing rapidly of causes such as China's power grid construction, traffic, tourism, communication, power overhead network is had higher requirement, and the traditional erection mode of overhead power line exposes the backward situation incompatible with developing rapidly of the development of the national economy gradually, can only set up a loop (i.e. three power lines) as 12 meters bars of traditional 10KV overhead wire, 15 meters bars can only set up secondary circuit, can not satisfy development need far away, the stringing corridor more and more is difficult to resolve determines, this is particularly outstanding in the city.
The purpose of this utility model is to design a kind of electric power netting safe running that satisfies technically, is fit to China's national power, the three-phase compact insulated overhead line assembly between 10KV overhead power line and 10KV power cable economically.
The utility model is by the triangle bracing frame that insulate, ply-yarn drill and insulated aerial lead are formed, triangle insulation bracing frame plane inner chamber is hollow, respectively there is a line embedding groove end at three angles, the bottom land semicircular in shape, the both sides of groove respectively have a ply-yarn drill to link axis hole or lock screw hole, the binding axis hole and the lock screw hole that adapt with triangle insulation bracing frame are arranged on the ply-yarn drill, and with triangle insulation bracing frame on the line embedding groove position adapt, the half slot that diameter is identical, link by connection shaft is movable between ply-yarn drill and the triangle insulation bracing frame, and fastening on it by securing member, the internal diameter and the insulated aerial wire diameter of the circle that two semicircles are synthetic adapt.
In this assembly, the insulated aerial lead is respectively steel core, aluminium stranded conductor, inner insulating layer, metal screen layer, insulating protective layer from inside to outside.
The ply-yarn drill that matches with triangle insulation bracing frame in the utility model can be ear shape ply-yarn drill.
The utility model utilizes triangle insulation bracing frame, three of correspondence is thoroughly done away with the edge lead aloft arranges equably, install an insulation bracing frame at a certain distance additional, make three to thoroughly do away with the edge lead certain small distance of maintenance each other, thereby dwindled taking up room of traditional type overhead power line greatly, make 15 meters bars can set up four loops and seven loops, solved the problem of power overhead network corridor difficulty, can save a large amount of power grid construction investments.
Describe the utility model in detail below in conjunction with accompanying drawing:

Fig. 3 ear shape ply-yarn drill front view
The left view of Fig. 4 Fig. 3
The right view of Fig. 5 Fig. 3
Fig. 6 has assembled the triangle support frame of ear card
The sectional view of Fig. 7 insulated conductor
Fig. 8 triangle insulation bracket assembly winding displacement panorama sketch
As seen from Figure 1, triangle insulation bracing frame is an almost plane triangle, and the end at its three angles all has a line embedding groove 1, the bottom of groove is a semicircle 2, both sides one side of groove is for installing the axis hole 3 of ply-yarn drill, and opposite side is a ply-yarn drill locking hole 4, and tripod inner chamber 5 is a hollow.On the ear shape ply-yarn drill shown in Figure 2 two holes are arranged, two holes 3,4 of the corresponding triangular support bracket of difference end, second circular groove 6 is also arranged on the ear shape ply-yarn drill, when ear shape ply-yarn drill sways, after the locking of triangle insulation bracing frame make-up, the circular groove that synthetic internal diameter of two semicircle slotted eyes on ply-yarn drill and the bracing frame and suspended insulated guide wire external diameter adapt.Fig. 6 is the schematic diagram that has assembled ear shape ply-yarn drill.
Figure 7 shows that the suspended insulated guide wire of special construction, its center is the aluminium stranded conductor 8 that steel core 7 is arranged, and aluminium stranded conductor outsourcing one deck inner insulating layer 9 is a metal screen layer 10 outside the inner insulating layer 9, and the skin of metal screen layer is an insulation protection skin 11.
Three suspended insulated guide wires are as shown in Figure 7 embedded respectively in three circular grooves of the triangle insulation bracing frame that is equally spaced, and, promptly constitute three-phase compact insulated overhead line assembly of the present utility model, winding displacement panorama sketch as shown in Figure 8 by ply-yarn drill locking.
The triangle insulation bracing frame that adopts in the present embodiment is an equilateral triangle, and the center distance of two circular grooves that it is adjacent is 150mm, and the spacing of equidistant two the adjacent triangle insulation bracing frames that separate is 4~6m.
Be erected at three-phase compact insulated circuit assembly on the electric pole as the assembly of above-mentioned structure, support by bracing frame, aloft arrange equably, kept less distance each other though three thoroughly do away with the edge leads, never collided, except that having preferably intensity, also dwindled taking up room of traditional type overhead power line greatly, make overhead transmission line can satisfy the requirement that electric power safety moves, solved the problem of power overhead network corridor difficulty, can be a large amount of power grid construction investment of power supply department saving.
