Description
Technical field
The present invention relates to a kind of high voltage cable strain insulator tension disk, particularly relate to a kind of wedge type aluminium alloy high pressure cable strain insulator wire-clamping device reducing bending stress, belong to power circuit technical field.
Background technology
Strain clamp is used for wire or lightning conducter to be fixed on non-rectilinear shaft tower strain insulator string, the effect of weighing anchor, also the bracing wire of bracing wire shaft tower is used for fixing, the difference of structure and mounting condition pressed by strain clamp, two classes can be divided into haply, the first kind: strain clamp will bear whole pulling force of wire or lightning conducter, grip of clamp is not less than 90% of mounted wire or the specified stretching resistance of lightning conducter, but not as electric conductor, this kind of wire clamp can also be pulled down after wire is installed, use separately, such wire clamp has bolt-type strain clamp and wedge shape strain clamp etc.; Equations of The Second Kind: strain clamp is except bearing whole pulling force of wire or lightning conducter, and again as electric conductor, therefore this kind of wire clamp is once after installing, just can not go dismounting again, be also called dead wire folder, owing to being electric conductor, the installation of wire clamp must be observed about the regulation of fitting operation code is conscientiously carried out.Strain clamp is used for corner, continues, and the connection of terminal, and at present, using more is spiral aluminium-clad steel wire, and spiral aluminium-clad steel wire has extremely strong strain insulator intensity, without concentrated stress, plays protect and the effect of auxiliary vibration damping optical cable.
At present, densely populated, trees are various, multicontaminated area, and we more and more adopt insulated conductor to go to replace plain conductor.It compare plain conductor have security reliability high, reduce line loss, the wire corrosion advantage such as little.When adopting insulated conductor, we it should be noted that owing to being be clipped on the external diameter of wire when strain clamp uses, instead of be clipped on the external diameter of conductor, therefore to go according to the external diameter of the external diameter of wire instead of conductor the model choosing used strain clamp, in addition, even tighten the screws is wanted when installing strain clamp, deposit wire after mounting and metal raw contact-making surface place, occur that the stress of conductor increases phenomenon, gentle breeze shakes or causes harness damage under other wire oscillatory condition and even occur that the grip of strain clamp to wire is less than 95% of wire-break power, and when high voltage cable needs to curve through, be difficult to effectively to protect the cable in high voltage cable knee not by the destruction of external forces, also the bending stress of high voltage cable cannot effectively be eliminated, and it also has much room for improvement to the clamping force of high voltage cable in existing cable gripping apparatus, can not effectively regulate high voltage cable across elasticity.
