摘要
差动继电器由于无可比拟的优点在电力系统尤其是母线保护中得到了广泛的应用 ,现在母线保护应用的差动继电器主要有 :电流差动继电器、比率差动继电器、大电流范围制动继电器、复式比率差动继电器。本文就这几种差动继电器原理和特点进行分析和加以比较。
Differential relays are widely used in power system,escially in busbar protection.Some main differential relays which are used in busbar protection at present include current differential relay,ratio check differential relay,strong current check differential relay and complex percentage differential relay etc. Their principles and characteristics are analyzed and compared in this paper.
