摘要:

针对过门二次电缆随仪表室门开合过程中的机械疲劳问题,提出一种基于弧形缓冲过渡的优化布线方案。通过增加过门线束预留长度并进行预弯折处理,构建弧形柔性结构,能够降低过门线束运动过程中20%的拉伸应变与34%的应力集中值,可有效提高线束柔韧性并延长绝缘层寿命。仿真实验及样机验证结果表明,所提方案有效提升了线束应变分布的均匀性,为智能开关柜的可靠运行提供了理论依据与实践指导。

Abstract:

The mechanical fatigue issue of door-crossing secondary cables during the opening and closing of instrument compartment doors is addressed by proposing an optimized wiring scheme based on an arc-shaped buffer transition.By increasing the reserved length of door-crossing cables and implementing pre-bending treatment, a arc-shaped flexible structure is constructed, achieving a 20% reduction in tensile strain and a 34% decrease in stress concentration values during cable movement.Cable harness flexibility is effectively enhanced and insulation layer lifespan is extended.Simulation experiments and prototype verification results demonstrate that the proposed solution significantly improves the uniformity of strain distribution in cable harnesses, providing both theoretical foundations and practical guidance for ensuring the reliable operation of intelligent switchgear.

Key words: switchgear instrument compartment, secondary cable, arc-shaped buffer transition, mechanical fatigue, wiring optimization
