  1. The protector makes the over - current value, zero - phase - sequence component, negative - phase - sequence and so on as protection criterions, in protection theory ; it makes atmel 8 - bit microprocessor at89c55wd as the core, with which the lattice lcd is linked, in hardware

    該保護裝置在保護理論上，以檢測過電流幅值、零序電流為判據；在硬體實現上，以atmel單片機at89c55為核心，外接圖形點陣式液晶顯示器、觸摸式按鍵等外設。
  2. A simple and easy operating criterion is put forward in accordance with the relation between positive - sequence component and negative - sequence component of stator current when the motor is in unbalance and single phase broken. based on analyzing the traditional inverse time - lag overloading protection of motors, an inverse time - lag operating equation with accumulating stator current is achieved, according to the differential equation of the heating and cooling while the current flows into the conductor

    在分析電動機傳統的反時限過負荷保護的基礎上，根據導體中流過電流時的發熱、散熱微分方程得到了累加定子電流的反時限過負荷保護動作方程，經簡化后得到累加定子電流的實用的反時限特性遞推公式。
  3. Aiming at the unsymmetrical three phase voltages from inverter after a failure, the dissertation get the relationship among the positive sequence ( ps ), negative sequence ( ns ) and the instantaneous symmetrical component of the ps, this build the foundation to detect the fault and to get the fault feature

    針對逆變器故障后的電壓輸出的不對稱性，利用對稱分量法對逆變器輸出信號進行分析，獲得了逆變器輸出信號的數字信號模型，為變頻調速系統的故障檢測與故障特徵提取奠定了基礎。 3
