核电厂跳机电磁阀供电卡件研究与优化

Research and Optimization of the Power Supply Card for Jumping Electromagnetic Valve of Nuclear Power Plant

跳机电磁阀影响着汽轮机发电机正常运行,核电厂均设计两路电源对电磁阀进行供电,防止失去一路电,导致进汽阀门关闭。论文针对该类型电磁阀的供电卡件进行研究,并提出优化方案。

The jumping electromagnetic valve affects the normal operation of the steamturbine generator.Two power supplies are designed to supply power for electromagnetic valves in nuclear power plants,so as to prevent the close of the intake valvewhen one power source is fault.The paper studies thepower supplycardof this type electromagnetic valve,andputs forward the optimization scheme.
