▒   概述 SUMMARY

输电及配电系统正常工作运行在工频信号下，然而随着大量非线性负荷用电设备的增加，注入电网中的谐波也随之增加，引起了电压及电流的波形畸变。传统的低压无功补偿装置 TSC( 晶闸管投切电容器组 ) 实现电容器快速无触点投切，但谐波的存在会使电容器与系统发生并联谐振，使谐波电流放大导致电容器损坏或晶闸管烧损。而供电系统常用的方法是采用接触器手动投切电力滤波器来消除谐波，自动化水平低，动作慢，无法做到适时稳定投切。低压动态无功补偿滤波成套装置 BSTSF( 用晶闸管投切滤波器 ) 实现了电压、无功、谐波的综合治理。

The normal operation of the transmission and distribution system is under the power frequency signal. However, with the increase of a large number of non-linear load electrical equipment, the harmonics injected into the power grid also increase, causing waveform distortion of voltage and current. The traditional low-voltage reactive power compensation device TSC (Thyristor Switching Capacitor Group) realizes fast contactless switching 

of capacitors, but the presence of harmonics causes parallel resonance between capacitor and system, causing capacitor current to be damaged or thyristor burning. . The common method of the power supply system is to manually cut the power filter by the contactor to eliminate the harmonics, the automation level is extremely low, the motion is slow, and the timely and stable switching can not be achieved. The low-voltage dynamic reactive power compensation filter device BSTSF (using a thyristor switching filter) realizes comprehensive control of voltage, reactive power and harmonics.

Extends the life of the dynamic compensation system.

♦ It can not only automatically track the system reactive load change, perform fast reactive power compensation, but also filter out the harmonic current in the power system to ensure that the user power factor is within the specified range. And because the capacitor is connected in series with the reactor, the amplification problem of the harmonics is avoided.
