Abstract
The utility model discloses a strain clamp comprising a strain aluminum pipe, a steel anchor connected with one end of the strain aluminum pipe, a drainage wire clamp, and a drainage plate connected with the strain aluminum pipe and the drainage wire clamp. One end of the drainage wire clamp is a hollow pipe, while the other end of the drainage wire clamp is a flat straight plate. Two protrusive boards are formed on one end of the drainage plate, wherein the end of the drainage plate is connected with the drainage wire clamp. A crack clamping the flat straight plate is formed between the two protrusive boards. The flat straight plate and the crack use interference fit and are further fixed by bolt fastening assemblies. The strain clamp increases the contact surface between the drainage plate and the drainage wire clamp and guarantees the transmission stability of large current by adjusting the structure of a conventional strain clamp.
Description
Technical field
The utility model belongs to electric armour clamp structural design field, is specifically related to a kind of strain clamp.
Background technology
Overhead transmission line is by strain tower the time, power transmission line need be fixed on the strain insulator of strain tower, and use wire jumper that overhead transmission line is carried out drainage to finish the leap connection of overhead transmission line, at this moment need to use strain clamp to finish fixing between overhead transmission line and the strain insulator.
The tradition strain clamp comprises the strain insulator aluminum pipe, is connected with at steel anchor, the drainage wire clamp of described strain insulator aluminum pipe one end and the drainage plate that connects described strain insulator aluminum pipe and described drainage wire clamp; One end of described drainage wire clamp is hollow tube, and the other end is straight plate; Described drainage plate contacts with described straight plate single face and is fixedly connected by the bolted assembly.Because drainage plate is that single face contacts with straight plate, contact-making surface is little, when big electric current by the time drainage plate and drainage wire clamp then can take place generates heat even burn red situation.
The utility model content
At the deficiency of pointing out in the background technology, the utility model is adjusted by the structure to traditional strain clamp, has increased the contact-making surface of drainage plate and drainage wire clamp, guarantees the stability of big current delivery.
The technical scheme that realizes the utility model purpose is:
A kind of strain clamp comprises the strain insulator aluminum pipe, is connected with at steel anchor, the drainage wire clamp of described strain insulator aluminum pipe one end and the drainage plate that connects described strain insulator aluminum pipe and described drainage wire clamp; One end of described drainage wire clamp is hollow tube, and the other end is straight plate;
The end that described drainage plate links to each other with described drainage wire clamp forms two flanges, forms the crack of the straight plate of clamping between two described flanges, and described straight plate and described crack are interference fit and further fix by the bolted assembly.
In the technique scheme, described crack has short slot near on the sidewall of described strain insulator aluminum pipe one end.
In the technique scheme, described drainage plate be set on the described strain insulator aluminum pipe and welding.
In the technique scheme, the bearing of trend of described drainage plate is identical with the bearing of trend of described drainage wire clamp.
In the technique scheme, described steel anchor is provided with draw ring.
In the technique scheme, described bolted assembly is made of bolt, supporting with it nut and packing ring.
The utlity model has positive effect:
(1) in the utility model, the end that described drainage plate links to each other with described drainage wire clamp forms two flanges, form the crack of the straight plate of clamping between two described flanges, described straight plate and described crack are interference fit and further fix by the bolted assembly.Can make drainage plate and drainage thread anchor clamps that enough big contact-making surface is arranged by the employing said structure, and reliable the connection, the stability of big current delivery guaranteed.
(2) in the utility model, described crack has short slot near on the sidewall of described strain insulator aluminum pipe one end, short slot is set can guarantees that two flanges have certain elasticity, the straight plate of drainage wire clamp can easier insertion crack in, and fully contact with the crack sidewall.
(3) in the utility model, by with described drainage plate be set on the described strain insulator aluminum pipe and welding, adopt this structure drainage plate reliably can be connected with the strain insulator aluminum pipe.
