摘要:

楔型耐张线夹在电力系统中被广泛应用,但在实际运行中经常出现导线脱落的问题,其问题根源为楔型线夹握力不足。对NXJ型耐张线夹的结构特点与安装方式进行简单介绍,并进行有限元仿真,通过改变NXJ型耐张线夹的楔角和楔块材料来改变线夹在运行期间的力学强度,得出线夹本体和导线的应力分布云图,对比得出不同条件下线夹对导线的握力情况,为NXJ型耐张线夹的优化提出参考。

关键词: NXJ型耐张线夹, 有限元仿真, 楔角, 楔块材料

Abstract:

Wedge-shaped tension clamps are widely used in power systems, but the problem of wire shedding often occurs in actual operation. The root cause of the problem is insufficient grip of the wedge-shaped clamp. A brief introduction to the structural characteristics and installation method of NXJ type tension clamp is elaborated, and finite element simulation is performed to change the mechanical strength of the clamp during operation by changing the wedge angle and wedge material of the NXJ tension clamp. The stress distribution cloud diagram of the clamp body and the wire is obtained, and the grip force of the clamp on the wire under different conditions is compared, which provides a reference for the optimization of the NXJ type tension clamp.

Key words: NXJ type tension clamp, finite element simulation, wedge angle, wedge material
