Abstract
The invention relates to a pre-twisted type composite stay insulator and belongs to the field of electricity protection. The pre-twisted type stay insulator comprises a pole stay, and is characterized in that the pole stay is in a sectional structure; the sectional pole stays are connected by insulators; the insulators are composite material insulators and a group of pre-twisted wires are wound on the insulators; and each pre-twisted wire is a tension resistant pre-twisted wire, and both ends of the pre-twisted wire are connected with the pole stay respectively. The stay insulator is simple in structure, low in manufacture cost and light in material and has the performance higher than that of the traditional ceramic insulator; in addition, the stay insulator is convenient to install and easy and convenient to operate, can be mounted by one normal repairer without being subjected to professional training, and thus the assembling working efficiency is greatly improved; and the device is small in volume, light in weight and high in strength, and the reliability of the stay insulator can be improved after the stay insulator is installed on the pole stay.
Description
Technical field
The present invention relates to a kind of preformed Compound wire drawing insulator, belong 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 wire and must install the guy insulator identical with the line voltage distribution grade.Guy insulator should be contained in minimum wire 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 wire, 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 wire, must the installing guy insulator.
The guy insulator majority is porcelain insulator on the power distribution network at present, weight is large, and is very easily damaged, and two of gold utensil connection employings are carved the line folder and are connected with backguy, installation procedure is complicated, 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 to again change backguy, cause unnecessary waste, cause in the real work installing and safeguard that guy insulator brings inconvenience.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of and can overcome defects, intensity is high, lightweight, easy for installation, quick, the high preformed Compound wire drawing insulator of installing efficient.
Preformed Compound wire drawing insulator provided by the invention, 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 composite material insulator, twines one group of preformed armor rods on it, and preformed armor rods is that its two ends of tension 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 processed through anti-Sand Skiing.
Preformed armor rods is the hurricane band that many wire spirals consist of.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.
The tension preformed armor rods twines along the groove of insulator, forms to draw mutually and be rightabout mutually to be squeezed on the insulator, forms interlocking and pre-pays backguy.
Preformed Compound wire drawing insulator provided by the present invention, 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 large, is installed in the reliability that can improve guy insulator in the backguy.
Description of drawings
Fig. 1 is insulator structure schematic diagram of the present invention;
Fig. 2 is preformed armor rods structural representation of the present invention;
Among the figure: 1, insulator; 2, groove; 3, preformed armor rods.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are 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 composite material insulator, twine one group of preformed armor rods on it, preformed armor rods is that its two ends of tension 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 processed through anti-Sand Skiing.Every preformed armor rods is the hurricane band that many wire spirals consist of.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.
The tension preformed armor rods twines along the groove 2 of insulator 1, forms to draw mutually and be rightabout mutually to be squeezed on the insulator, forms interlocking and pre-pays backguy.Preformed armor rods 3 is processed by anti-Sand Skiing, and for bearing the tension preformed armor rods of strong pulling force, it is shaped as the hurricane band that many wire spirals of a row consist of, 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 tension preformed armor rods are pull-type mutually, groove 2 along insulator is laid, article two, tension 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 larger mutual extruding force of pulling force is larger, does not drop out so that preformed armor rods 3 can not come off from insulator 1.
