磁控电抗器励磁绕组感应高压对励磁系统的影响及对策

Effect of Exciting Winding Induction High Voltage of Magnetic Control Reactor on the Excitation System and Its Countermeasure

磁控电抗器励磁绕组两端的交流电压本应为零伏,但是由于磁控电抗器结构设计^([1-10])的原因及制造工艺的对称偏差等因素的影响,导致励磁绕组两端存在着较高甚至很高的交流电压,成为引发励磁故障及本体故障的隐患。在分析励磁绕组感应高压产生的根源的基础上,分析感应高压的危害,提出减小感应高压影响的措施。

The AC voltage at the both ends of the excitation winding of the magnetic control reactor should be zero volts, but because of the magnetic control reactor structure design and the influence of such factors as the symmetrical deviation of manufacturing process, there is a higher AC voltage at both ends of the exeiting winding, which is a hidden danger that can cause excitation faults and ontology faults. Based on the analysis of the root causes of exciting winding induction high voltage, this paper analyses the detriments of induction high voltage, and proposes the measures to diminish the influence of induction high voltage.
