摘 要: 介紹了基于單片機的繞組溫控儀智能化改造的背景、原理及軟硬件方案。以單片機為主控單元的智能匹配器替代傳統(tǒng)的變流器,通過對熱模擬實驗的閉環(huán)控制實現(xiàn)了加熱電流的自動調節(jié),從根本上解決了繞組溫度測量不準確的問題。測試結果證明該方案適用于各種型號的繞組溫控儀的智能化改造,具有較高的應用價值。
關鍵詞: 繞組溫控儀;熱模擬實驗;智能匹配器;單片機;閉環(huán)控制

Abstract: Introduction was made to the background, principle, software and hardware plan of single chip-based intelligent transformation 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.
       Key words: winding temperature controller; thermal analog experiment; intelligent matcher; single chip; closed-loop control
