摘　　要：目的:改进旋转阳极控制电路,实现过流保护。方法:分析CT-C2800旋转阳极控制原理,通过故障检修发现电路设计的不足,并提出改进方法。结果:当旋转阳极发生堵转过流时,保护电路起作用,使旋转阳极停止旋转。结论:实现了旋转阳极控制板的过流保护,并延长了球管寿命。Objective： To improve rotating anode circuit to achieve over-current protection. Methods： We anlayzed the controlling principle of CT-C2800 rotating anode to find the lack of circuits design by trouble-shooting, and give some advice for its improvement. Results： When an over-current appeared, the protection circuit worked to stop the rotating anode. Conclusion： The over-current protection on the rotating anode has been achieved and the life span of the tube has been prolonged.

关 键 词：旋转阳极 过流保护 改进
