兖州煤炭设计研究院与靖江电控厂、济宁、郑州、邯郸开关厂联合开发研制的节电型660V低压成套配电装置于1991年7月在无锡,由中国统配煤矿总公司基建局主持召开了鉴定会。 节电型660V低压成套配电装置,系为适应大型、特大型煤矿地面生产系统及选煤厂发展需要的先进产品,也适用于电力、冶金、石油、化工等工矿企业。其包括,固定面板式配电屏;电动机控制屏;封闭落地式、嵌墙式动力配电箱及抽出式开关柜五个系列,一次方案共378个。与目前国内已定型的类似产品相比,它除具有主电路便于组成各种供电方案;辅助电路适合各种不同控制系统(且与主电路方案对应),结构采用组装式,设计选用非常方
Yanzhou Coal Design and Research Institute and Jingjiang Electric Control Plant, Jining, Zhengzhou, Handan switch plant jointly developed by the energy-saving 660V low-voltage power distribution unit in July 1991 in Wuxi, by the China National Minerals Corporation presided over by the Infrastructure Bureau Appraisal meeting. Energy-saving 660V low-voltage power distribution unit, is suitable for large and large coal mine production systems and coal preparation plant development needs of advanced products, but also for electricity, metallurgy, petroleum, chemical and other industrial and mining enterprises. Including fixed panel panel; motor control panel; closed floor, embedded wall power distribution box and withdrawable switch cabinet five series, a total of 378 programs. Compared with the similar domestic products, it has the main circuit to facilitate the composition of a variety of power supply solutions; auxiliary circuit for a variety of different control systems (and the main circuit solutions), the structure of the assembly type, the design selection of very side
