FMLF (7%) 带谐波保护的电力电容器

FMLF (7%) 带谐波保护的电力电容器

POWER CAPACITOR FOR HARMONIC PROTECTION

Description 产品简介

These LIFASA capacitors are designed to be connected in series with INR or INA reactors, in order to build up low tuning (fr = 189 Hz) Harmonic Protection Filters (Capacitor rated powers indicated in the table, are achieved when connected to the reactors). FMLF capacitors have been specially developed taking into account that, when connected to the reactors, they work at a voltage higher than the supply voltage. Inductance value of reactors and capacitance value of FMLF capacitors are specially calculated to ensure that, when connected in series, the reactive power of the filter is as given on the name plate.

这类电容器设计为与INR 或 INA 电抗器串联，以建立低调谐 (fr = 189 Hz) 谐波保护滤波器（当连接到电抗器时，表中所示的电容器额定功率可以达到）。 FMLF 电容器是经过专业开发的，主要考虑到当电容器连接到电抗器时，它们的工作电压高于电源电压。 电抗器的电感值和FMLF电容器的电容值经过专业计算，以确保在串联时，滤波器的无功功率如铭牌所示。
