这篇论文简要地论述了在综合保护电路中使用一种新颖微机的研制。该保护电路为防止接地故障、不平衡负载、单相工作、过载、短路以及含阻抗的低值真正短路故障提供了保护措施。其特点是:仅用了三个传统的电流互感器就准确检测了上述提到的所有故障。研制的综合保护电路主要是一片INTEL8085A 微处理器,计划将其安装在矿用开关中,用于处理上述各种故障。当微机指示出所检测的故障类型时,驱动开关跳闸。
This paper briefly discusses the development of a novel microcomputer for integrated protection circuits. This protection circuit provides protection against ground faults, unbalanced loads, single-phase operation, overload, short-circuit and true low impedance faults with low values. It is characterized by: Accurate detection of all the above mentioned faults with just three conventional current transformers. Developed integrated protection circuit is mainly an INTEL8085A microprocessor, it is planned to be installed in the mine switch, used to deal with the various failures. When the microcomputer indicates the detected fault type, the drive switch trips.
