基于AVR单片机的电力变压器试验自动测试装置的设计与实现

摘要

An automatic testing device for power transformer tests based on AVR microcontroller is designed and implemented in this paper. The hardware scheme and software design method of the device are described in detail. The device; composed of high speed and precision A/D conversion chip MAX 1320 and AVR microcontroller ATmegel28 taken as the core; can perform automatic tests for no—load test and load test of power transformers; which improves the efficiency and avoids human errors. Besides; the device has high-performance of small size and low cost.%设计并实现了一款基于AVR单片机的电力变压器试验自动测试装置,详细介绍了该测试装置的硬件实现方案和软件设计思路.本测试装置采用高速、高精度的A/D转换芯片MAX1320,并以AVR单片机ATmega128为核心,不仅实现了对电力变压器空载试验和负载试验的自动测试,提高了效率,避免了人为误差,而且具有体积小、成本低的优点.
