摘要: 国内核电发电机励磁市场长期被进口设备垄断。对于采用旋转整流元件作为中间放大环节的两机或三机核电励磁系统,其整流元件的好坏对机组安全稳定运行至关重要。目前国内市场上并无成熟可靠的旋转整流元件检测及告警装置,给核电励磁设备国产化带来困难。在对旋转整流元件空间布置进行研究的基础上,提出了NES6131旋转整流元件检测及告警装置的检测原理,并详细介绍了装置软硬件设计,经田湾核电站2号机组现场一系列试验表明,该装置功能完善、性能可靠、动作准确、可移植性高,特别适用于安装有大轴缺口位置探测线圈和旋转整流元件电流探测线圈的大型无刷发电机组。

Abstract: Rotating bridge rectifier is the integral part of the power unit, the quality and running status of which is very important for the safe and stable operation of generator units. However, there is no proven detection and alarming device for rotary rectifying element in the domestic market. In this paper, an introduction is made to the NES6131 rotating rectifier element detection and alarm device newly developed by NARI TECH. Through a series of field tests in the No.2 generator units of Tianwan Nuclear Power Plant, the NES6131 is fully functional, reliable, accurate and high portable, and is especially suitable for large brushless generators which is equipped with position detection coil and current detection coil.

Key words: rotating bridge rectifier, NES6131, detection, alarming
