一、概述我公司自成立以来,各6~(KV)系统的铁磁谐振现象屡屡发生,如东炼、前进、向阳、动力厂……等,多次造成停电事故,引起生产中断。后来各厂陆续采取了一些措施,取得了一定效果。但由于在采取这些措施时大都没有搞清其消振的机理,也没根据自己系统的具体情况和参数做定量的分析计算,只是仿照外单位的作法,因此未能根本解决问题。比如动力厂二电站的6~(KV)系统,75年前
I. Overview Since the establishment of our company, all 6 ~ (KV) system of ferromagnetic resonance occurs frequently, such as the East refining, forward, sun, power plant ......, etc., repeatedly causing power outages, causing production interruptions. Later, some factories took some measures in succession and achieved certain results. However, most of them failed to find out the mechanism of vibration suppression when they adopted these measures, and did not make quantitative analysis and calculation according to the specific conditions and parameters of their own systems. They merely imitated the practice of outside units and therefore failed to solve the problems at all. For example, Power Plant II 6 ~ (KV) system, 75 years ago
