基于单片机的绕组温控仪智能化改造

摘要

介绍了基于单片机的绕组温控仪智能化改造的背景、原理及软硬件方案。以单片机为主控单元的智能匹配器替代传统的变流器，通过对热模拟实验的闭环控制实现了加热电流的自动调节，从根本上解决了绕组温度测量不准确的问题。测试结果证明该方案适用于各种型号的绕组温控仪的智能化改造，具有较高的应用价值。%Introduction was made to the background, principle, software and hardware plan of single chip-based intelligent transforma-tion of winding temperature matcher. The traditional converter was substituted by the intelligent matcher taking the single chip as the main control unit. The closed-loop control of thermal analog experiment realized automatically adjusting of heating current, to solve the problem of winding temperature incorrect measurement fundamentality. The test result shows that the plan is applicable to intelligent transformation of various models of winding temperature controller, with higher application value.
