Abstract

The isolated contact of pyrobreaker is used to disconnect the electrical connection immediately upon pyrobreaker current contact opening and establish long-term insulation capability. The performance of isolated contact can directly affect the safety and reliability of the quench protection system. A combined research approach based on multi-physics simulation and experimental methods is proposed to study the explosive fracture process of the isolated contact in pyrobreaker. The dynamic propagation of the explosive shock wave is simulated using the Arbitrary Lagrangian-Eulerian (ALE) algorithm combined with fluid-solid coupling, allowing for a detailed analysis of the pressure distribution on the isolated contact under shock loading and the time-dependent response of their fracture velocity. To validate the numerical model, a shock wave-driven explosion experiment was designed and conducted. Then the high-speed camera was used to capture the displacement of insulation cylinder for cutting contact. The experimental results exhibited a high degree of consistency with the numerical simulation, and demonstrates that the design method of pyrobreaker is effective and reliable.
100ka高温断路器隔离触头动态特性仿真与实验研究
高温断路器的隔离触点用于在高温断路器电流触点断开时立即断开电气连接,并建立长期绝缘能力。隔离触点的性能直接影响到失稳保护系统的安全性和可靠性。提出了一种基于多物理场模拟与实验相结合的研究方法,研究了火电断路器中隔离触点的爆炸断裂过程。采用结合流固耦合的任意拉格朗日-欧拉(ALE)算法对爆炸冲击波的动态传播进行了模拟,详细分析了冲击载荷作用下孤立接触点上的压力分布及其破裂速度随时间的响应。为了验证数值模型,设计并进行了激波驱动爆炸实验。然后利用高速摄像机捕捉切割接触时绝缘筒的位移。实验结果与数值模拟结果具有较高的一致性,证明了该设计方法的有效性和可靠性。
