一、问题的提出由我厂与建筑机械研究所共同研制的KJT 型可控硅交流调压调速装置(以下简称“装置”)用于 QT-80吨米多用自升塔式起重机上。有关装置的特点、技术性能和规格等请参见本刊1981年第6期第17页及封四照片。将这种可控硅技术用于塔式起重机上,在我国过去大多为单台的实验性装置,而且往往中途夭折,这就谈不上批量生产和推广使用。据调查了解,其原因当然是多方面
First, the question put forward by our factory and construction machinery research institute jointly developed KJT-type SCR AC voltage regulator device (hereinafter referred to as “device”) for QT-80 tons of multi-purpose self-elevating tower cranes. For the characteristics of the device, technical performance and specifications, please see the issue of No. 6, 1981, page 17 and the closure of four photos. This SCR technology used in tower cranes, mostly in our country as a single experimental unit, and often die in the middle, it can not be put into mass production and promotion. According to the survey, of course, the reasons are many
