摘要

真空断路器(vcb)具有高的中断能力和优异的介电强度。此外,vcb可以中断高频电流。这可能导致瞬间多次重燃。本文主要尝试在MATLAB中对vcb进行仿真,从而提出一种更接近现实生活中vcb行为的新模型。该模型是为了模拟vcb的瞬态行为而开发的,涉及到电流斩波、介电电阻和中断能力等几个参数。本文研究了预击、重燃和斩波的概率性质。

Transient model of the vacuum circuit breaker-probabilistic approach
Vacuum circuit breakers (VCBs) are known with high interruption capability and excellent dielectric strength. Moreover, VCBs can interrupt high-frequency currents. This can lead to instantaneous, multiple re-ignitions. This paper mainly attempted to simulate VCBs in MATLAB, so as to propose a new model desirably close to how the behave in real-life. Developed to simulate the transient behavior of VCBs, the new model involves several parameters such as current chopping, electrical resistance in dielectric and interruption capability. The prestrike, re-ignition, and the probabilistic nature of chopping has been investigated in this paper.
