Abstract
The utility model belongs to a hardware fitting for an electric power circuit and particularly relates to an insulating sleeve of an overhead lead wire. In the overhead transmission line which is applied at present, a connection lead wire is mostly supported by a straight-line rod tower through a suspension insulator string, so as to cause defects as follows: the sheet structure of an insulator is complicated and the combined construction is complex; the weight is heavy and the rod tower has a high load; and a large space exists between the lead wires due to a large size, the transmission line is not compact and the transmission system is high in construction cost. The purpose of the utility model is to provide the insulating sleeve of the overhead lead wire which is characterized in that a hollow tube structure with an appearance outline which is in the shape of waves with unequal external diameters is composed of a surface layer, an insulating layer and an interface layer, wherein the surface layer is made of a weather-proof, dust-proof and water-repellent material for avoiding pollution flashover; the insulating layer is made of a cross-linked polyethylene material for insulating the lead wire from the rod tower; and the interface layer is made of a semiconductor material for enabling an electric field of the lead wire to be uniform; and a cavity is arranged in the middle of the hollow tube structure. The insulating sleeve of the overhead lead wire is used for replacing the suspension insulator string of the straight-line rod tower, thereby reducing the lightning stroke, decreasing the load of the rod tower, and enabling the transmission line to be more compact by shortening the interval between the rod tower and the lead wire.
Description
Technical field
The utility model belongs to a kind of power circuit gold utensil, also can be described as a kind of aerial condutor annex, definite a kind of aerial condutor insulating sleeve of saying so.
Background technology
In the overhead transmission line of using at present, straight line pole adopts suspension insulator string support and connection lead more, and its shortcoming is to show that mainly the insulator chip architecture is complicated, and the combination construction between every is loaded down with trivial details; Insulator string weight is big, makes shaft tower load high; The insulator string volume is big, makes lead phase interbody spacer big, and transmission line is not compact, and the transmission system cost is high.
Summary of the invention
The purpose of the utility model is to provide a kind of aerial condutor insulating sleeve.It is characterized in that being made up of the cavity of weather-proof antifouling top layer and insulating barrier, interface layer and break-through lead, during application, aerial condutor is penetrated in the cavity, outside employing fastening means is connected it fixing with shaft tower, thereby solves existing defective.
In order to solve the problem that prior art exists, the technical scheme that the utility model adopts is:
A kind of aerial condutor insulating sleeve; Appearance profile is the corrugated tubular structure that does not wait external diameter, and the antifouling hydrophobic material of weather resistant is as the top layer, and the middle level is the insulating barrier that crosslinked polyethylene (XLPE) material constitutes; Internal layer is the boundary layer that semi-conducting material constitutes; In order to contact wire, the centre is a cavity, in order to pass lead.During application, aerial condutor is penetrated in the guidewire lumen, outside employing fastening means is connected it fixing with shaft tower.The top layer of waveform appearance profile and the antifouling hydrophobic material of weather resistant makes rainwater, dewdrop, water droplet etc. freely tumble along the waveform surface more easily; Improved self-cleaning ability and reduced the winter, autumn the bad phenomenon such as freezing of freely not causing because water, droplet etc. flow generation, avoid pollution flashover; Lead that passes in the middle of the insulating barrier that crosslinked polyethylene (XLPE) material constitutes makes and shaft tower insulation, and improve the alternate class of insulation of each lead of shaft tower; The boundary layer that semi-conducting material constitutes prevents that in order to improve Electric Field Distribution the conductive line surfaces electric field is concentrated, with the lead equipotential, avoids producing partial discharge between lead and the insulating barrier.
The beneficial effect of the utility model is that the suspension insulator string of alternative straight line pole reduces shaft tower load, dwindles shaft tower lead phase interbody spacer, makes transmission line compact more.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing is the vertical section sketch map of the utility model embodiment.
In the accompanying drawing, 1. top layer 2. insulating barriers 3. boundary layers 4. cavitys.
Embodiment
A kind of aerial condutor insulating sleeve; Appearance profile is the corrugated tubular structure that does not wait external diameter, and the antifouling hydrophobic material of weather resistant is as top layer 1, and the middle level is the insulating barrier 2 that crosslinked polyethylene (XLPE) material constitutes; Internal layer is the boundary layer 3 that semi-conducting material constitutes; In order to contact wire, the centre is a cavity 4, in order to pass lead.During application, aerial condutor is penetrated in the cavity 4, outside employing fastening means is connected it fixing with shaft tower.The top layer 1 of waveform appearance profile and the antifouling hydrophobic material of weather resistant makes rainwater, dewdrop, water droplet etc. freely tumble along the waveform surface more easily; Improved self-cleaning ability and reduced the winter, autumn the bad phenomenon such as freezing of freely not causing because water, droplet etc. flow generation, avoid pollution flashover; Lead that passes in the middle of the insulating barrier 2 that crosslinked polyethylene (XLPE) material constitutes makes and shaft tower insulation, and improve the alternate class of insulation of each lead of shaft tower; The boundary layer 3 that semi-conducting material constitutes prevents that in order to improve Electric Field Distribution the conductive line surfaces electric field is concentrated, with the lead equipotential, avoids producing partial discharge between lead and the insulating barrier 2.
Claims (1)
1. aerial condutor insulating sleeve is characterized in that not waiting the corrugated tubular structure of external diameter, and the boundary layer that insulating barrier that is made up of the top layer and the crosslinked polyethylene material of the antifouling hydrophobic material of weather resistant and semi-conducting material constitute is formed, and the centre is a cavity.
