摘　　要：设计了一种新的微机保护装置,解决了传统的铁磁互感器微机保护装置在大电流电器试验中因磁饱和而导致的保护失灵的问题,也解决了采用Rogowski线圈电流传感器的微机保护装置在小电流电器试验中因准确性差而导致的保护不准确的问题。A new type of microprocessor-based protection device is designed.It not only solves the problem of protection failure caused by magnetic saturation of traditional microprocessor-based protection device of ferromagnetic transformer in high current electrical apparatus test,but also solves the problem of inaccurate protection caused by poor accuracy of microprocessor-based protection device using Rogowski coil current sensor in small current electrical apparatus test.
