Circuit Analysis and Maintenance of High-Voltage Generator of PANalytical XRF Spectrometer

X射線管高壓發(fā)生器是熒光光譜儀的核心部件之一，它提供一個(gè)高精度的的高壓供電電源給Ｘ射線管，是獲得高精度分析的必要條件。它包括多路電源變換器(MPPC)和HT整流器(HT油箱)，二者共同產(chǎn)生一個(gè)正極性的高壓(HT)和燈絲供電電流。本文介紹了帕納科(原荷蘭飛利浦) PW2440熒光光譜儀高壓發(fā)生器的工作原理及其故障維修。

The X-ray tube high voltage generator is one of the core components of fluorescence spectrometer which provides high-accuracy high-voltage power supply to the X-ray tube and it is necessary to obtain high-precision analysis results. The generator includes multiple power converter (MPPC) and HT rectifiers (HT tank), which together produce a positive polarity high voltage (HT) and filament power supply current. Working principle and maintenance are described of PANalytical (formerly Philips) PW2440 fluorescence spectrometer high voltage generator.
