Abstract

An improved rod-type composite insulator string and a connection structure are disclosed. The rod-type composite insulator string is formed by a glass fiber resin core rod, a synthetic material sheath, an umbrella skirt and connection fittings of two ends. An end portion of the connection fitting of one end is a cylindrical tubular snap ring. One side of the snap ring is provided with a gap. The connection fitting of the other end is a flat head with a circular hole. Simultaneously, the connection structure of the insulator string is disclosed. The structure comprises the rod-type composite insulator string, strain clamps and a socket-clevis eye. A snap ring portion of the rod-type composite insulator string is connected with the strain clamp through the socket-clevis eye. A flat head portion of the other end is directly connected with another strain clamp through a bolt. Through improving a connection point of the rod-type composite insulator string, the socket-clevis eye does not need to be added and a connection distance is shortened; construction personnel can easily connect the rod-type composite insulator string with the strain clamps directly; materials are saved and construction is convenient.

Description

Modified model bar type composite insulator string and syndeton
Technical field
The utility model relates to bar type composite insulator string technical field, specifically a kind of modified model bar type composite insulator string and syndeton.
Background technology
The insulator that overhead transmission line is conventional has pin insulator, suspension insulator, cross arm insulator, rod insulator and composite insulator etc., rod insulator is wherein a porcelain integral body, and its effect is equivalent to the suspension insulator that some suspension insulators form.But its weight is lighter, and length is short, can save steel, can also reduce shaft tower height.The shortcoming of stick type ceramic insulator is that manufacturing process is complicated, and cost is higher, and in service easily because vibration is ruptured.Insulation division in the middle of its basic structure comprises and the connecting portion at two ends, in all rod insulators, the connection at two ends is all the joint of plug-in at present, as depicted in figs. 1 and 2, when needs are connected with strain clamp, need to use socket-clevis eye excessively to connect, as shown in FIG., although this structure is fine use also,, by analyzing us, find, socket-clevis eye only plays a connection function, and what still in current all circuits, use is all this structure.By analyzing us, find, shortcoming is as follows, the one,, a bar type composite insulator string need to be used two socket-clevis eyes when being connected with strain clamp, each socket-clevis eye is by 27 yuan of calculating, an angle pole will be saved 162 yuan, and next 10kV circuit of ordinary circumstance calculates one of light socket-clevis eye by 30 corners, strain insulator, terminal just need to purchase 4860 yuan of funds.The 2nd, workmen is owing to being subject to the restriction of belt length, and while connecting strain clamp on bar, time-consuming effort again, has also wasted material simultaneously.
Utility model content
So for the problems referred to above, the utility model provides a kind of modified model bar type composite insulator string and syndeton, by improving the structure of tie point, do not need to add socket-clevis eye, shortened insulator string distance, workmen is directly connected excellent type composite insulator string with strain clamp, saved material more convenient construction.
The technical scheme in the invention for solving the technical problem is: a kind of modified model bar type composite insulator string, by the connection gold utensil at glass fiber resin plug, synthetic material sheath, full skirt and two ends, formed, it is characterized in that, the connection hardware end of one end is cylindrical tube shape snap ring, and the side at snap ring is provided with a breach, the connection gold utensil of the other end is a round-meshed homalocephalus.
The surface of described connection gold utensil has hot galvanizing rete.
A kind of syndeton of modified model bar type composite insulator string, comprise bar type composite insulator string, strain clamp and socket-clevis eye, described bar type composite insulator string adopts said structure, it is characterized in that, the snap ring portion of described bar type composite insulator string is connected with strain clamp by socket-clevis eye, and the homalocephalus portion of the other end is directly connected with another strain clamp by bolt.
Described strain clamp is bolt-type strain clamp.
The beneficial effects of the utility model are: by bar type composite insulator string being passed through to improve tie point, save a socket-clevis eye, shorten to connect distance, workmen just can directly be connected excellent type composite insulator string easily with strain clamp, saved material more convenient construction.

Fig. 1 is the mounting structure figure of the bar type composite insulator string before improving;
Fig. 2 is the bar type composite insulator string structural representation before improving;
Fig. 3 is the bar type composite insulator string structural representation after improving;
Fig. 4 is the mounting structure figure of the bar type composite insulator string after improving;
In figure: 1 full skirt, 2 connect gold utensil, 3 snap rings, 4 homalocephalus, 5 bar type composite insulator strings, 6 strain clamps, 7 socket-clevis eyes,
Embodiment
As shown in Figure 3 and Figure 4,
A kind of modified model bar type composite insulator string, by the connection gold utensil 2 at glass fiber resin plug, synthetic material sheath, full skirt 1 and two ends, formed, agent structure and existing structure are basic identical, and improvements are to have carried out architecture advances for the connection gold utensil of one end wherein.Wherein, the connection hardware end of one end is cylindrical tube shape snap ring 3, and is provided with a breach in a side of snap ring, for being connected with the socket-clevis eye of W type, the connection gold utensil of the other end is and round-meshed homalocephalus 4, can be directly connected with strain clamp.Meanwhile, on the surface that connects gold utensil, have hot galvanizing rete, weatherability is better.
A kind of syndeton of modified model bar type composite insulator string, comprise bar type composite insulator string 5, strain clamp 6 and socket-clevis eye 7, described bar type composite insulator string adopts said structure, wherein, the snap ring portion of bar type composite insulator string 5 is connected with strain clamp 6 by socket-clevis eye 7, socket-clevis eye is wherein power industry standard part, there is polytypic available, can be with reference to the < < socket-clevis eye > > of GB2324-85.The homalocephalus portion of the insulator string other end is directly connected with another strain clamp by bolt.Strain clamp is wherein bolt-type strain clamp.Strain clamp is used for corner, continues, and the connection of terminal.Spiral aluminium-clad steel wire has extremely strong strain insulator intensity, without concentrated stress, optical cable is played to the effect of protection and auxiliary vibration damping.Strain clamp is used for wire or lightning conducter to be fixed on non-rectilinear shaft tower strain insulator string, and the effect of weighing anchor, is also used for fixing the bracing wire of bracing wire shaft tower.
Except the technical characterictic described in specification, be the known technology of those skilled in the art.
