SJK型电控和SJR型金属水冷电阻器,是我国在史无前例的无产阶级文化大革命中,自行设计自己制造的一种新型的矿井提升机的电控系统,这种电控设备虽具有体积小、重量轻、节省金属、安装方便和改善调速性能的优点。但根据我矿几年来运行情况表明:它也还存在一些需要改进的地方。下面就我矿几年来为了满足生产的需要,在领导的大力支持下, SJK-type electric control and SJR-type metal water-cooled resistors, is our country in the unprecedented proletarian cultural revolution, to design their own to create a new type of mine hoist electronic control system, this electronic control device has a small size, Lightweight, metal-saving, easy to install and speed-tuning. However, based on the operation of mine for several years, it shows that there are still some areas for improvement. Here I mine in recent years in order to meet the needs of production, with the strong support of the leadership,
