电力系统的安装调试与维护过程中,接地是保证系统正常运行和人员安全的关键措施。为了提高接地装置的可靠性以满足工作要求,本文提出一种力封闭锁合型高压输电防脱型接地装置,分析装置的结构特点与锁合能力的关系,并对其锁合能力和受力性态进行理论解析,得到结构力封闭锁合和接触力的计算公式,为封闭锁合设计提供理论参考。通过多体动力学虚拟仿真分析,得出鸭舌材料和表面质量状态及弹簧施力方向对接触力的影响曲线,为寻找提高接触锁合能力的措施提供指导方向。

In the process of installation, debugging and maintenance of the power system, grounding design is the key measure to ensure the normal operation of the power system and the safety of personnel. In order to improve the reliability of the grounding device to meet the requirements of the work, a force closed high voltage transmission anti-stripping type grounding device is proposed. The relationship between the structure characteristics of the device and the locking capacity has been analyzed. Besides, the theoretical analysis of locking ability and mechanical behavior is also carried out, the formula provides a theoretical reference for self-locking design. Through the virtual simulation analysis, the influence curve of the duck tongue material, the surface quality and the direction of the spring force to contact force are obtained, which provides the guiding direction for the measures to improve the device＇s lock ability.
