The preformed composite stay insulator which comprises an electric pole stay wire is characterized in that the electric pole stay wire has a segmental type structure; segmented electric pole stay wires are connected through insulators; the insulators are made of composite materials; each insulator has a group of preformed wires wound thereon; the preformed wires are tension-resistant preformed wires; and the two ends of each preformed wire are respectively connected with the electric pole stay wire. The preformed composite stay insulator which has the characteristics of simple structure, low cost, portable materials, convenient installation and simple operation enables greater performances than a conventional ceramic insulator. An installation worker is not required to be professionally trained. A common maintainer can make the preformed composite stay insulator installed. The installation efficiency is thus greatly improved. Furthermore, the preformed composite stay insulator which has the advantages of small volume, lightness and high strength can have the reliability enhanced when arranged on the stay wire.
Description
Technical field
The utility model relates to a kind of preformed Compound wire drawing insulator, belongs to the electric power protection field.
Background technology
" rural area low-voltage power technical regulation " regulation: pass through with the pole guy that is close to lead and must install the guy insulator identical with the line voltage distribution grade.Guy insulator should be contained in minimum lead once, should guarantee that guy insulator should be less than 2.5m apart from ground under guy insulator breaks the backguy situation once." overhead insulating distribution line designing technique rules " regulation: the backguy of reinforced concrete pole must be installed guy insulator or take other insulation measures when being passed between the lead, and guy insulator should be less than 2.5m apart from ground.From above national standard, no matter be city or rural area, no matter be the suitable plain conductor of insulated conductor, pass through and near the pole guy of lead, must the installing guy insulator.
The guy insulator majority is porcelain insulator on the power distribution network at present, weight is big, and is very easily damaged, and two of gold utensil connection employings are carved the line folder and are connected with backguy, the installation procedure complexity, inconvenience is installed, needs to prepare a large amount of instruments early stage, installing efficient is lower, particularly the insulation in guy period of the day from 11 p.m. to 1 a.m is installed in existing backguy additional, need change backguy again, cause unnecessary waste, cause in the real work installing and safeguard that guy insulator brings inconvenience.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome above-mentioned defective, and intensity height, in light weight, easy for installation, quick, the high preformed Compound wire drawing insulator of installing efficient.
The preformed Compound wire drawing insulator that the utility model provides, comprise pole guy, it is characterized in that, described pole guy is segmentation structure, the pole guy of segmentation is connected by insulator, insulator is the composite material insulator, twines one group of preformed armor rods on it, and preformed armor rods is that its two ends of strain insulator power preformed armor rods are connected with pole guy respectively.
Described insulator is polymorphic structure, once is pressed into integral structure by composite material.Polymorphic structure can be square body, cuboid, spherical, polygonal body etc.
Described insulator surface has right-angled intersection formula semicircular arc groove.
Described preformed armor rods is two bars, and the inner surface of every preformed armor rods is handled through anti-Sand Skiing.
Preformed armor rods is the hurricane band that many wire spirals constitute.Insulator surface has right-angled intersection formula semicircular arc groove, twines trend as preformed armor rods, and groove is semicircular arc, prevents that effectively preformed armor rods from coming off.
Strain insulator power preformed armor rods twines along the groove of insulator, and formation is drawn mutually and is the rightabout mutual extrusion on insulator, forms interlocking and pre-pays backguy.
Preformed Compound wire drawing insulator provided by the utility model, simple in structure, cheap, material is light, and the performance that exceeds the traditional porcelain insulator is arranged; And it is convenient to install, easy and simple to handle, and installation personnel need not pass through professional training, and the trip service personnel get final product a people and install, and has increased substantially the operating efficiency of installing; This device volume is little, and quality is light, and intensity is big, is installed in the reliability that can improve guy insulator in the backguy.
Description of drawings
Fig. 1 is the utility model insulator structure schematic diagram;
Fig. 2 is the utility model preformed armor rods structural representation;
Among the figure: 1, insulator; 2, groove; 3, preformed armor rods.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Preformed Compound wire drawing insulator as shown in Figure 1, comprise pole guy, described pole guy is segmentation structure, the pole guy of segmentation is connected by insulator 1, insulator 1 is the composite material insulator, twine one group of preformed armor rods on it, preformed armor rods is that its two ends of strain insulator power preformed armor rods are connected with pole guy respectively.Insulator 1 is square body, once is pressed into integral structure by composite material, and there is right-angled intersection formula semicircular arc groove on the surface of insulator 1.Preformed armor rods 3 is two bars, and the inner surface of every preformed armor rods is handled through anti-Sand Skiing.Every preformed armor rods is the hurricane band that many wire spirals constitute.There is right-angled intersection formula semicircular arc groove 2 on insulator 1 surface, twines trend as preformed armor rods 3, and groove 2 is semicircular arc, prevents that effectively preformed armor rods from coming off.
Strain insulator power preformed armor rods twines along the groove 2 of insulator 1, and formation is drawn mutually and is the rightabout mutual extrusion on insulator, forms interlocking and pre-pays backguy.Preformed armor rods 3 is handled by anti-Sand Skiing, and for bearing the strain insulator power preformed armor rods of strong pulling force, it is shaped as the hurricane band that many wire spirals of a row constitute, in order to be wrapped on the steel strand wire.
During installation, square composite material insulator 1 para-electric bar stayguy direction, article two, 3 one-tenth intersections of strain insulator power preformed armor rods are pull-type mutually, groove 2 along insulator is laid, article two, strain insulator power preformed armor rods 3 is wound into respectively in the backguy, and is stressed when backguy, and the mutual pull-type preformed armor rods 3 that intersects tightly is attached to and meets in the insulator groove 2, the more big mutual extrusion power of pulling force is more big, makes preformed armor rods 3 can not come off from insulator 1 and drops out.
