论文部分内容阅读
1.行频过低:当行频长时间处于过低状态时因行电流增大而烧损“行管”。2.行激励不足:当行激不足时,“行管”管压降、管耗增大而易烧坏“行管”。3.行逆程电容开路或容量减少,致使“行管”集电极脉冲电压幅度增大而易被高压击穿。4.行输出变压器(高压包)短路;致使行电流大增而烧“行管”。5.S校正电容短路,使行电流大增。6.供电电压突然升高(稳压系统失控)而“行管”被高压击穿。7.“行管”质量不好。8.其他(如阻尼二极管开路、升压电容短路、硅柱短路等)。
1. The line frequency is too low: when the line frequency is too low for a long time, the line current burns “line management”. 2. Inadequate incentive: When the line is not enough, the “tube” tube pressure drop, increased tube consumption and easy to burn “under control.” 3. Line reverse circuit capacitance or reduced capacity, resulting in “on the tube” collector pulse voltage amplitude increases easily punctured by high voltage. 4. Line output transformer (high voltage package) short circuit; resulting in a substantial increase in current and burning “line management.” 5.S correction capacitor short circuit, so that the current surge. 6. Sudden increase in supply voltage (regulator system out of control) and “line management” was high-voltage breakdown. 7. “Governed” poor quality. 8. Others (such as damping diode open circuit, short circuit of boost capacitor, short circuit of silicon column, etc.).
