QBG-180/6000R矿用隔爆高压软起动装置是由我公司与美国ROCKWELL公司及淮南矿业集团合作开发的一种高压电气传动产品。它采用了先进的电力电子器件和数字司环（电流）控制技术，具有操作简单方便和使用故障率极低的优点，是星～三角起动器，自耦变压器和液力偶合器等旧式起动装置理想的更新换代产品。2000年12月22日由国家煤炭行业委员会组织并主持，邀请了国家科学院和相关行业专家15名，在淮南矿业集团张集煤矿井下召开现场新产品鉴定会，在会上本产品被鉴定为“国际先进水平，填补了国内外空白”。
该装置主回路每相由反并联的可控硅串联而成，通过控制可控硅的触发角度控制输出电压的大小。电机起动时，本装置按照预设的起动曲线增加电机的端电压使电机平滑加速，达到全速后，旁路接触器接通。电机起动完毕后，本装置继续监控电机，并提供各种保护。
QBG-180/6000R Mining Explosion-proof High-voltage Soft Starter is high voltage electric drive, which has been cooperative developed by Rockwell Automation, Huainan Mining Industry Group and our company. The soft starter use advanced electronic and digital current control technology, which is operated easily and simply and its error rant very low. It is the ideal product to instead of triangle start drive and hydrodynamic coupling.

QBG-180/6000R Mining Explosion-proof High-voltage Soft Starter is a high voltage electric drive, which has been cooperatively developed by Rockwell Automation, Huainan Mining Industry Group and our company. The soft starter uses advanced electronic and digital current control technology, which is operated easily and used with extremely low error rate (故障率用failure rate更好些). It is the ideal up-to-date product to substitute traditional Star Delta , auto transformer and hydrodynamic coupling starters. The National coal industry trade committee organized and held a new product appraisal meeting for it at site down the pit of Zhangji coal mine, Huainan Mining industry Group. 15 experts from academies and relative trades were invited to attend this meeting; they drew a conclusion that the technology of this product reached international advanced level and filled up domestic blank area.

Main circuit in each phase consists of SCRs reverse parallel connected in serial. The applied
