To reduce the monitoring errors of power grid parameters and lower the failure rate of power grid transformers,an intelligent power distribution transformer terminal based on ARM is designed. The hardware structure of this intelligent distribution transformer terminal is composed of acquisition layer,communication interface layer,core control layer and function realization layer. The software architecture is composed of the user program and Linux kernel. The acquisition layer collects the data of power grid transformer,calculates the parameters by using Fourier algorithm and then transmits it to the communication interface layer;the communication interface layer adopts Ethernet and GPRS communication methods to expand a variety of communication interfaces to meet the communication needs of distribution transformer terminals,and timely transfer the data to the core control layer;and the core control layer adopts ARM processor with fast processing speed and pipeline structure and it can process data quickly and accurately and feed back to the function realization layer to realize the related functions of distribution transformer terminal.The test results show that: the monitoring error of distribution transformer related parameters of the intelligent distribution transformer terminal is low,and the fault incidence rate is low and the success rate of fault short message transmission is high after the application of the distribution transformer terminal,and the remote communication status between the distribution transformer terminal and the master station is good.
