摘要
集成电路保护的抗干扰、零漂、电源、元器件质量问题是造成集成保护误动的主要因素 ,该文就嵩屿电厂的厂用 6kV电动机过热保护多次误动原因进行分析并提出改进措施。图
Quality defects of integrated circuit elements appertaining to protection against disturbances, zero swerving, as well as of the power source, may cause protection to act erroneously. The paper analyses the sources that caused overheating protection of Songyu Power Plant's 6kV house service motor to go into action erroneously at several occasions, while simultaneously presenting means of improvement.
