摘要:

地震作为一种严重的自然灾害,对电力系统的安全稳定运行构成了重大威胁。断路器是保障电力供应连续性和可靠性的重要元件,对其抗震性能开展研究十分必要。以某型中压真空断路器为例,通过响应谱分析、多体动力学仿真及抗震性能试验,深入探讨了其在地震环境下的抗震性能。仿真与试验结果表明,该断路器在结构强度、部件工作完整性及触头弹跳三方面均具有较高的安全系数,满足地震环境下的工作要求。

Abstract:

Earthquakes,as severe natural disasters, pose significant threats to the safe and stable operation of power systems.Circuit breakers, critical components for ensuring continuous and reliable power supply, require thorough investigation of their seismic performance.A medium voltage vacuum circuit breaker is focused on, and its behavior under seismic conditions is evaluated by employing response spectrum analysis, multibody dynamics simulation, and seismic performance testing.The results demonstrate that the circuit breaker exhibits high safety margins in structural strength, operational integrity of components, and contact bounce control, meeting operational requirements during earthquake.

Key words: medium-voltage vacuum circuit breaker, seismic performance, response spectrum analysis, multibody dynamics simulation
