0.前言反峰过荷是加速器常见故障之一,但因其涉及面广,另部件多且有不少贵重部件,检修起来比较困难。影响加速器反峰过荷的因素很多,通常问题出在高压部分,高压部分检测采用二分之一法。1.故障现象控制台面板上显示调制器故障,出束PFN电压由18.6KV逐渐地变零,随之调制器触摸屏故障显示等显示“clipper cur”。2.故障分析在放电回路中,当每次闸流管导通而使人工线充分放电动作结束
0. Introduction Anti-peak overload is one of the common faults of accelerators, but it is more difficult to repair because of its wide range of involved parts, many parts and many expensive parts. Affect the accelerator anti-peak overload of many factors, usually the problem is part of the high pressure, high-pressure part of the test using one-half method. 1. Symptom The modulator panel is displayed on the console panel. The PFN output voltage gradually decreases from 18.6KV to 0V, and the display shows “clipper cur” on the display of the touch panel fault of the modulator. 2. Fault Analysis In the discharge circuit, when each thyristor conduction and artificial line full discharge action ended
