Abstract
A strain clamp dedicated to a high strength steel core aluminum alloy stranded conductor lead is mainly composed of a strain clamp body, a steel anchor, a jumper conductor clamper and a fastening piece. An aluminum die tube of the strain clamp body is made of an aldural material and produces plastic distortion with the aluminum alloy stranded conductor of the steel core aluminum alloy stranded conductor under a pressure so as to burden the partial tension of aluminum alloy stranded conductor of the high strength steel core aluminum alloy stranded conductor. The steel anchor produces plastic distortion with the steel core part of the steel core aluminum alloy stranded conductor under the pressure so as to burden the partial tension of steel anchor of the high strength steel core aluminum alloy stranded conductor, and at the same time a drainage plate and a jumper conductor clamper adopt a multiaperture connection method to facilitate the adjustment and installation of a jumper wire. The front end of the aluminum die tube is in compression joint with a lead and the tail end thereof is connected in the middle of the steel anchor through pressure in order that the whole strain clamp is integrated with the steel core aluminum stranded conductor, and the ring-shaped part of the tail end of the steel anchor is fixed on an iron tower.
Description
Affiliated technical field
The utility model relates to a kind of strain clamp of transmission line, and the method for the enough crimping of energy is held an end of high strength steel core aluminium alloy conductor, and is fixed on the iron tower by insulator string.
Background technology
Present enforcement along with domestic transferring electricity from the west to the east, the construction of high height above sea level, heavy icing area, UHV transmission line at a distance,, its lead adopts heavy in section high strength steel core aluminium alloy stranded conductor more, and supporting with it strain clamp requires big grip, big load, bears the huge tension force of lead.Because strain clamp in the past all adopts the pure aluminum tube manufacturing, intensity is little, for being complementary with high strength steel core aluminium alloy stranded conductor part load, by strengthening strain clamp body aluminum pipe external diameter, this is suitable on small bore high strength steel core aluminium alloy stranded conductor, but the grip that strain clamp provides can't satisfy the requirement of strength of heavy in section high strength steel core aluminium alloy stranded conductor.
Simultaneously when using high strength steel core aluminium alloy stranded conductor, because its intensity height, hardness are big, difficulty especially when wire jumper is installed is not easy to put in place.
Summary of the invention
High strength steel core aluminium alloy stranded conductor has adopted the high-strength aluminum alloy pipe with the strain clamp body, because aluminium-alloy pipe intensity is much higher than pure aluminum tube, and being higher than the intensity of aluminium alloy stranded conductor, its grip that provides can be complementary with high strength steel core aluminium alloy stranded conductor part load fully.The drainage plate of strain clamp adopts porous yoke plate form, possesses and adjusts the function that length is installed, and makes things convenient for the length adjustment of wire jumper, makes wire jumper be easy to install.
The technical scheme in the invention for solving the technical problem is: strain clamp is made up of strain clamp body (1) and steel anchor (2), drainage wire clamp (3), securing member (4) four parts.Strain clamp body (1) is to be connected as a single entity by welding by aluminium aluminium hydraulic pressed connecting pipe (5) and drainage plate (6); Drainage plate (6) and drainage wire clamp (3) have a plurality of bolts hole (9), connect by securing member (3); The tail end of steel anchor (2) is (7) ringwise, link to each other with electric power pylon by insulator string; Aluminium aluminium hydraulic pressed connecting pipe (5) is used for partly being connected with the aluminium alloy stranded conductor of steel core aluminium alloy stranded conductor, the front end steel aluminium hydraulic pressed connecting pipe (8) of steel anchor (2) is used for partly being connected with the steel core of steel core aluminium alloy stranded conductor, the both is by producing plastic deformation under pressure, thereby is combined into integral body with aluminium alloy stranded conductor and steel core respectively.
1. the aluminium aluminium hydraulic pressed connecting pipe (5) of strain clamp has adopted the high-strength aluminum alloy pipe, because aluminium-alloy pipe intensity is much higher than pure aluminum tube, with lead after compression, the grip that provides can be complementary with high strength steel core aluminium alloy stranded conductor part load fully, satisfies instructions for use.
2. the drainage plate of strain clamp (6) adopts porous yoke plate form, possesses and adjusts the function that length is installed, and makes things convenient for the length adjustment of flexible jumper, makes wire jumper be easy to install.
The beneficial effects of the utility model are:
1. the aluminium aluminium hydraulic pressed connecting pipe (5) of strain clamp has adopted the high-strength aluminum alloy pipe, with lead after compression, the grip that provides can be complementary with high strength steel core aluminium alloy stranded conductor part load fully, satisfies instructions for use.
2. the drainage plate of strain clamp (6) adopts porous Bolt Connection form, possesses and adjusts the function that length is installed, and makes things convenient for the length adjustment of wire jumper, makes wire jumper be easy to install.
