磁性部件柜的失效原因分析及改进措施

Failure Cause Analysis and lmprovement for Magnetic Component Cabinet

磁性部件柜是核动力装置重要的热控装置之一，由于原磁性部件柜是以自饱和磁放大器为基本元件，因而具有一定的缺陷。为了进一步提高核动力装置的安全可靠性，必须对原磁性部件柜进行技术改进。研制与原磁性部件柜性能相同的新型部件，取代原磁性部件柜，将磁性元件全部改成集成电路组成的各功能部件。本文全面分析了原磁性部件柜失效的原因，并提出了具体的改进措施。

The magnetic component cabinet is an important thermal control device fitted on the nuclear power.Because it used a self saturation amplifier as a primary component,the magnetic component cabinet has some boundedness.For increasing the operation safety on the nuclear power,the paper describes a new scheme.In order that the magnetic component cabinet can be replaced,the new type component cabinet is developed.Integrate circuit will replace the magnetic components of every function parts.The paper has analyzed overall failure cause for magnetic component cabinet and adopted some measures.
