摘要
直流工频阻断滤波器由电抗器和电容器组成工频并联谐振回路,用于限制直流回路上的工频电流,保证直流系统的安全运行。本文通过对直流阻断滤波电容器装置和电容器单元额定电压、额定容量、绝缘配合、电容器内部结构、场强等方面进行研究,介绍了直流工频阻断滤波电容器装置主要设计依据和重要参数的计算方法。
Resonance circuit is composed of DC power-frequency blocking filter, reactor and capacitor bank to limit power-frequency current in AC circuit and to assure safe operation of AC system. In this paper,the DC blocking filtering capacitor and capacitor unit are studied in the aspects of rated voltage, rated capacity, insulation coordination, internal structure of capacitor and field strength ete and the main design base for DC power frequency blocking filtering capacitor and calculation method of important parameters are introduced.
