概述:
在工业企业的供电系统中，有大量的非线性负荷存在如晶闸管整流器，变频器等，会产生大量的谐波电流注入电网，引起电流和电压的波形畸变，这些设备是供电系统内的谐波源，如让这些谐波电流无约束的在线路中流动必将影响周围用电设备的安全使用和用电质量。
在主要谐波源设备附近，就近连接一台调谐滤波器，它的投切与谐波源设备同步进行，这是解决谐波干扰，就地解决无功补偿的一种好办法。哈工大威瀚公司为不少用户量身定做了许多设计方案，达到理想的经济效益和实际使用效果。
JSF 系列调谐滤波器与 TSF 的区别在于控制方式的不同，它可以固定投切，也可以与要补偿的设备同时投切。受控操作，接触器投切，由于它的特殊设计，可以完全避免谐波电压，谐波电流的递增放大。每台柜的谐振频率按用户要求设计，调试，通常是 5 次（ 250 HZ ）， 7 次（ 350 HZ ）。它在基波频率下呈容性，即产生无功功率可以进行功率因数的补偿，在谐波频率下起调谐滤波作用，从电网中消除低次谐波的部分含量（约 50% ）

JSF-Series Tuning Filters
INTRODUCTION：
In the power supply system of the industry and enterprise, there are a large amount of non-linear loads, such as thyristor rectifier and frequency converter, that can produce much harmonic current injecting to the power grids and lead the current and voltage to deform. These devices are the harmonic source in the supply system. If these harmonic current flows into the grids freely, it will badly impact on the safety and quality of the electricity in the surrounding electronic equipments.
A tuning filter should be connected near to the main harmonic equipments. Its switch should be synchronous with the harmonic source, which is a good way to eliminate the harmonic disturbing and compensate the reactive power on the spot. Weihan carries out various designs and schemes according to the customer, and attain desirable economic benefits and practical impacts.
The difference between JSF-series tuning filters and TSF is its control pattern. JSF can be controlled at not only the certain time, but the simultaneously compensating time. Due to its specific design, JSF can entirely eliminate the harmonic current and voltage from increasing and amplifying by degrees. The resonating frequency of each designed cupboard and debugged from the customer demands, is usually 5th (250 HZ), 7th (350 HZ). It presents as capacity at the basic frequency, means JSF which is producing the reactive power can compensate the power factor, plays a filtrating and tuning impact on the resonant frequency, and eliminates the parts of the low harmonic power grids (almost 50%).
