| Abstract: | This article introduces hardware technical scheme of a general micro-processor based protective device for large high voltage transformers,and analyzes countermeasures applied for operation refusal and maloperation. Then,the protective functions, the administration unit and the selection of core chips are carefully described. This paper also introduced module-based programming method and its advantage ,the administration unit software structure ,and solved realization of generality. With powerful DSP and ARM core chips,this device has perfect protective and communication functions ,high reliability ,and so on. This device is satisfying modern power system. |
