Description
Technical field
The present invention relates to a kind of supporting gold utensil that is used for the built on stilts phase line (OPPC) of Optical Fiber Composite, be specifically related to a kind of strain insulator gold utensil that is used for the built on stilts phase line of Optical Fiber Composite.
Background technology
The strain insulator gold utensil, promptly strain clamp is the crucial gold utensil of erecting optical cables, generally is used for lead or lightning conducter are fixed on the strain insulator string of non-rectilinear shaft tower, plays the anchoring effect, also can be used to the fixedly backguy of backguy shaft tower.
The general technology condition of strain insulator gold utensil is following:
Electric substation should be not less than 65% of the specified stretching resistance of lead that continued with the strain insulator gold utensil to the lead grip;
The radius of curvature of screw bolt-type strain insulator gold utensil should be not less than 8 times that are mounted diameter of wire;
The outlet of gold utensil and the outlet that continues all should make slick and sly bell mouth shape;
As the gold utensil of electric conductor, when rated voltage was passed through maximum permissible current for a long time, the temperature rise of gold utensil should be not more than the temperature rise that is mounted lead;
The resistance of gold utensil should be not more than 1.1 times that are mounted isometric conductor resistance;
When gold utensil bore electrical load, its ampacity should be not less than the ampacity that is mounted lead.
The strain insulator gold utensil is different by structure and mounting condition, can be divided into two types haply:
The first kind: the strain insulator gold utensil will bear 90% of lead or the specified stretching resistance of lightning conducter, but not as electric conductor.This type gold utensil can also be pulled down after lead is installed, and uses separately.Such gold utensil has bolt type strain insulator gold utensil, wedge shape gold utensil and compression-type strain insulator gold utensil etc.
Wherein, compression-type strain insulator gold utensil operation principle and characteristics are following:
Compression-type strain insulator gold utensil is made up of aluminum pipe and steel anchor, and the steel anchor steel core with the anchoring steel reinforced aluminium conductor that is used for continuing puts the aluminum pipe body then, makes metal produce plastic deformation with pressure, thereby makes gold utensil and wire-bonds as a whole.By the version that adopts usually, the steel anchor of gold utensil bears the whole pressure of lead, so its mechanical strength matches with the specified stretching resistance of lead.
The installation of compression-type strain insulator gold utensil can be adopted hydraulic pressure or detonation pressure.When adopting hydraulic pressure, the punching block that must be suitable for certain specification compresses with hydraulic press.The compression-type strain insulator gold utensil of typing, no matter steel pipe and aluminum pipe are circle, the compression back is a regular hexagon, the hexagon opposite side is of a size of 0.866 times of external diameter of pipe.
The characteristics of screw bolt-type strain insulator gold utensil then are: clamp adopts the high-strength aluminum alloy manufacturing; Appearance is bright and clean, long service life; Easy to install; No electric energy loss is energy-conservation certified product.
The grip of general bolt type strain insulator gold utensil is 90% of the specified stretching resistance of lead; Use the strain insulator gold utensil, its grip desirable 65% for the long-pending lead of especially big sectional plane, expanded conductor and insulated wire.
Second type: the strain insulator gold utensil is except that the whole pulling force that bear lead or lightning conducter, again as electric conductor.Therefore this type gold utensil is in case after installing, and just can not go dismounting again, claims that again dead wire presss from both sides.Owing to be electric conductor, the installation of gold utensil must be observed the regulation of relevant fitting operation rules and conscientiously carried out.
Existing strain insulator gold utensil is applied in defective on the OPPC and is that mainly stress concentrates, and no matter is screw bolt-type, and still crimp type strain insulator gold utensil all is that the pulling force with whole span section inside conductor has all focused on strain insulator gold utensil place, causes the interior light unit of lead impaired easily.
