    VEGT BoomPQ有源滤波补偿概述

    The growing use of power electronic devices is causing an increasing level of harmonic distortion in the electrical system which very often leads to problems with capacitor installations. This is the reason why more and more energy suppliers demand the installation of detuned capacitor systems

    电力电子器件越来越多的使用导致电气系统中异常的谐波失真水平的增加其中经常引起电容器装置的问题。这就是为什么越来越多的电力供应商要求安装失谐电容器系统的原因。

  • A detuned capacitor system performs the function of power factor improvement whilst preventing any amplification of harmonic currents and voltages caused by resonance between capacitors and inductances in the electrical system.

    一个失谐电容器系统执行无功补偿的功能时能防止电气系统中电容与电感之间的谐振引起的任何谐波电流和电压的升高。

    By adding an appropriately rated series reactor to the power capacitor, both elements form a resonant circuit with a resonant frequency below the lowest order harmonic in the system (usually the 5th). All frequencies above this resonant frequency now see this circuit as inductive hence eliminating the possibility of dangerous resonances being set up between the capacitors and system inductances provided the reactor has been dimensioned properly.

    通过向电力电容器上添加额定值适当的串联电抗器,这两个元件形成一个具有低于系统中最低阶谐波的谐振频率(通常为5次)的谐振电路。只要选择正确电抗器的规格,这个谐振频率以上的所有频率此刻都将这个电路视为电感从而消除了在电容器和系统电感之间建立危险谐振的可能性。

    VIGOR VGET™ DR series Reactors are made by High-precision iron-core stamping sheets and copper or aluminum. The complete assembly is impregnated using a sophisticated vacuum-pressure impregnation. They are dried and impregnated in a vacuum with environmentally friendly, low-styrole resin which ensures they can withstand high voltages, have low noise levels, and offer a long operating life. Depending on their rated power, the reactors are provided with either terminal blocks or terminal lugs/cables. In case of aluminum band solid copper terminals are permanently attached to the winding conductor, using cold pressure welding. This is reliably connected with the aluminum band by a special, well-proven welding method.

    VIGOR VGET™ DR系列电抗器由高精度铁芯冲压薄片以及铜或铝制成整个组件使用先进的真空压力浸渍工艺浸渍。它们被干燥并在真空中浸渍环保的低苯乙烯树脂确保它们能够承受高电压,低噪声水平以及长寿命。根据其额定功率,电抗器配有端子排或接线端子/电缆。电抗器如果使用铝条绕组,则需要使用冷压焊的方法把实心铜条的终端焊接在绕组导线上。这是一个特殊的,经过充分验证的与铝带可靠地连接的焊接方法。

    High-precision iron-core sheet stamping eliminates inductive tolerances between the three phases, as well as the ability to precisely tune the reactor. Through the computer-controlled winding machine using cold welding technology will be the copper terminal of the welding wire in the aluminum belt or copper belt coil, for you to solve the cable and the terminal due to improper contact between the overheating problems.

    高精度铁芯薄片冲压可消除三相之间的电感公差,也能够精确调谐电抗器。通过计算机控制的卷绕机采用冷压焊接技术将铜条的接线端子焊接在铝带线圈或铜带线圈上,为您解决电缆与接线端子之间因接触不当产生的过热问题。

    An integrated thermal switch (reversible) allows external monitoring and / or disconnection of the reactor in the event of impermissible buildup of heat.

    一个集成的热敏开关(可逆)允许外部监测和/或在不可容许的热累积的情况下断开电抗器。
