一、攻克难题 早在60年代初期,我国新研制成功了一项应付电网变故的具有中国自己特色的电机保护技术——SBZ技术。创造这一崭新技术的人,就是核工业总公司电机运行技术公司总工程师蒋宗道。 蒋宗道1960年留学回国,当时正是我国严重经济困难时期,核工业处于初创起步阶段。由于外国专家的突然撤退,一系列技术难题只能靠我们自己的科技人员去解决。 当时核工业某铀同位素分离工厂,对供电电网的供电可靠性和连续性要求很高,外国专家设计文件中规定的电网器降切除时间不得大于0.2秒,否则就会引起核心部分机组的大范围停机甚至损坏,这将给国 First, to overcome the problem As early as the early 60s, China has successfully developed a new type of motor protection technology, SBZ technology, that has its own characteristics in response to grid changes. The person who created this new technology is Jiang Zongdao, the chief engineer of the company’s motor operating technology company. Jiang Zongdao returned to China to study in 1960. At that time, it was a period of severe economic hardship in China. The nuclear industry was at the initial stage of development. Due to the sudden withdrawal of foreign experts, a series of technical problems can only be solved by our own scientific and technical personnel. At that time, a uranium isotope separation plant of the nuclear industry had high requirements on the reliability and continuity of power supply to the power supply grid. The cut-off time of the grid device specified in the foreign expert’s design document should not exceed 0.2 second, otherwise it would cause a large range of core units. Downtime or even damage, which will give the country
