Abstract
The invention discloses a NLD bolt-type strain clamp for lines. The NLD bolt-type strain clamp is characterized by comprising a clamp main-body which is prepared from a ZL101A aluminium alloy material and undergoes T6 treatment and press strips installed on the clamp main-body through U-shaped bolts. The press strips are prepared from the ZL101A aluminium alloy material and undergoes the T6 treatment. The clamp main-body is provided with a horizontal-axis bolt which is fixed through a nut and a cotter. The strain main-body and the press strips are molded by low-pressure casting of the aluminium alloy material ZL101A. Thus, strength of the clamp is raised, and strength and handgrip test results of the clamp completely meet requirements. The temperature of the NLD bolt-type strain clamp is similar to the actual operating temperature of a wire, and hysteresis and eddy current will not happen basically. According to the invention, heating phenomenon of an original NLD bolt-type strain clamp due to hysteresis and eddy current is solved, and electric energy loss caused by heating of the NLD bolt-type strain clamp is avoided. Thereby, operating costs of a line are reduced greatly.
Description
Technical field
The present invention relates to power transmission and transformation gold utensil technical field, particularly a kind of circuit NLD bolt-type strain clamp.
Background technology
High-tension line is widely used NLD bolt-type strain clamp, for carrying the wire of electric current to be fixed on insulator string.NLD bolt-type strain clamp GB product material is agate iron at present, for magnetic material, resistance to wire clamp main body and transverse axis bolt form closed structure, so circuit is in through-flow running, at NLD bolt-type strain clamp, place can produce magnetic hysteresis, vortex phenomenon, thereby makes the heating of NLD bolt-type strain clamp.Can reduce the intensity of NLD bolt-type strain clamp like this, weaken antiwear property, also increase the loss of electric energy.Not only there is potential safety hazard in this kind of NLD bolt-type strain clamp thus, and increased circuit operating cost.
Summary of the invention
Technical problem to be solved by this invention is to provide for the existing above-mentioned technical problem of existing NLD bolt-type strain clamp that a kind of intensity is high, plasticity good, superior performance, safe and reliable circuit NLD bolt-type strain clamp.
In order to realize this purpose, the solution of the present invention is as follows:
A kind of circuit NLD bolt-type strain clamp, it is characterized in that, comprise the wire clamp main body that employing ZL101A aluminum alloy materials is made and processed through T6 and by U bolt, be arranged on the press strip in described wire clamp main body, the press strip of described press strip for adopting ZL101A aluminum alloy materials to make and process through T6; In described wire clamp main body, transverse axis bolt is installed, described transverse axis bolt is fixed by bolt and nut of clip.
Owing to having adopted technical scheme as above, strain insulator main body of the present invention and press strip adopt the moulding of aluminum alloy materials ZL101A low pressure casting, have improved wire clamp intensity, and its intensity and handgrip exercise result meet the demands completely.NLD bolt-type strain clamp temperature of the present invention is close with wire actual motion temperature, does not substantially have the generation of magnetic hysteresis, vortex phenomenon.Solved original NLD bolt-type strain clamp due to the fever phenomenon that magnetic hysteresis, vortex phenomenon produce, avoided the electric energy loss that causes because of the heating of NLD bolt-type strain clamp, thereby greatly reduced circuit operating cost.
