由水利水电科学研究院自动化所,上海立新电器厂、葛洲坝水力发电厂联合研制的“磁场断路器—高能氧化锌压敏电阻灭磁系统”于八六年元月六日在葛洲坝水力发电厂六号机上试验成功,三月廿七日在五号机上正式安装使用。安装、试验及二百多天的运行表明:灭磁系统元件少、接线简单、结构合理便于维护检修。磁场断路器分断快,机构动作可靠。
“Magnetic field circuit breaker - high-energy zinc oxide varistor demagnetizing system” jointly developed by Institute of Automation of Water Conservancy and Hydropower Research Institute, Shanghai Lixin Electrical Appliance Factory and Gezhouba Hydropower Plant was put into operation at Gezhouba Hydropower Station VI on January 6, The number of aircraft on the successful test, on March 27 officially installed on the 5th machine to use. Installation, testing and operation of more than two hundred days show that: the components of the demagnetizing system are few, the wiring is simple, and the structure is reasonable for easy maintenance and overhaul. Magnetic circuit breaker breaking fast, institutions reliable action.
