基于AT90S8535单片机的干式变压器智能温度控制器设计

Intelligent Temperature Controller Design on Dry-type Transformer Based on AT90S8535

设计了由AT90S8535单片机构成的干式变压器智能温度控制器 ,可同时检测 4路温度 ,使测温误差小于± 0 5℃ ,能满足电磁干扰的各项试验要求 ,现场运行稳定 ;另外 ,该控制器具有RS485数据接口功能 ,用户可通过人机接口控制变压器冷却风机的起、停 ,设定报警及跳闸阀值 ,具有较大的应用价值。

A temperature controller specially for dry type transformer based on AT90S8535 has developed The controller,monitors four tunnels' temperture simultaneously,has the error of measurement less than ±0 5℃ and meets all kinds of laboratory requirements of electromagnetic interference There is a good field stability in operation.Moreover,it has a communication function of RS485.Users can operate on off of the cooling fan on dry type transformer,set warning and trip threshold through human machine interface.The design is of great value in application.
