Electric conductor construction aluminum cable steel reinforced (ACSR) crimping system

Abstract

The invention discloses an electric conductor construction aluminum cable steel reinforced (ACSR) crimping system. The system comprises a conductor core clamping block, a left clamping sleeve and a right clamping sleeve, wherein the right clamping sleeve is hinged with one end of the left clamping sleeve; the conductor core clamping block comprises a left clamping block and a right clamping block; the left clamping block and the right clamping block are matched with clamping slots which are arranged in the left clamping sleeve and in the right clamping sleeve; locking bolts are arranged in the clamping slots; after the left clamping block and the right clamping block are combined, the size of the inner arc diameter is matched with the specification of a conductor core; operation arms are arranged on the left clamping sleeve and on the right clamping sleeve; the operation arms are connected through latch mechanisms on the operation arms. The system is time-saving and labor-saving; when the system is used for ACSR more than 20mm, the conductor is relatively large in force after being dispersed, the operation arms are pressed to be locked at proper positions and move toward the dispersion end, so that the operation is time-saving, labor-saving, convenient and rapid, and the operation efficiency is high.

Description

technical field [0001] The invention relates to the field of auxiliary tools for wire crimping in substation engineering construction, in particular to a steel-cored aluminum stranded wire crimping device for power wire construction and a method for using the same.

AI Technical Summary

Problems solved by technology

[0002] At present, during the construction and wiring of power substation projects, it is necessary to make copper or aluminum joints at both ends of wires with various wire diameters. Special crimping pliers are used for small diameter wires, which is more convenient to make and can meet the quality requirements of joints; Diameter wires are generally used in high-current occasions. When there is a poor contact, it will cause the contact to heat up. In severe cases, the contact will be melted and the wire will be blown. Through observation, it is found that the following problems exist in the production process:

[0003] 1) Since the wire is multi-core, its ends are easy to disperse, and it is difficult to insert it neatly into the sleeve of the crimping tube. After crimping the sleeve, the outer layer of the end of the wire cannot be in reliable contact with the inner wall of the crimping tube, and there is poor contact When the wire is crimped, heat is inevitable; the current crimping process is: wire binding, scribing and mold crimping. Before the wire is crimped, the wire is bound with aluminum wire, which is troublesome and consumes more wire

[0004] 2) When crimping short wires, especially those with a length of less than one meter, when one end is crimped and the other end is crimped, the wire core at the end of the wire will be under the action of the pressing force. Some loose wires are prone to so-called "lantern flowers". Under the action of the "skin effect" of the current, the loose wires will overheat and burn out in severe cases, but there is currently no effective way to avoid them.

Its disadvantages are: 1) The range of application is small, and it can only crimp a single ACSR. When encountering ACSR with various diameters, it is necessary to carry multiple above-mentioned devices, which is inconvenient to use

2) It is time-consuming and labor-intensive to use the above-mentioned device. When the steel-reinforced aluminum stranded wire is more than 20mm, the tension will be relatively large after the wires are scattered. It is time-consuming and labor-intensive to crimp with wing nuts, which is inconvenient to operate and low in operating efficiency.

3) When the above-mentioned device is used to crimp the aluminum-steel wire with a diameter of 10 mm or more, the device will be pressed against the rear side of the insertion part of the wire end, and the end will remain loose, making it difficult to insert the end into the crimping tube

4) It is necessary to press the upper and lower dies by hand to snap the aluminum core into the device, which is time-consuming and laborious, and inconvenient to use
