LWKK®无功补偿低压滤波电抗器

LWKK® Reactive Power Compensation LowVoltage Filter Reactor  

在用电器飞速发展进步的情况下,各种电力电子装置在电力系统、工业、交通及家庭中的应用也日益广泛,谐波的存在和对电力系统的影响变得更加普遍和严重,无功补偿产品中的电力电容器已经逐渐不适合单独使用在各类场合,电容器和供电系统的阻抗之间会产生的并联谐振会造成谐波电流的严重放大,滤波电抗器的加装,可以在选配合适电抗率以后,电容器电抗器组合可吸收对应固定次数谐波电流30%到50%左右。防止并联谐振及谐波电流流入电容器,避免谐波电流发生放大,对整个电力系统起到一定净化作用。

LWKK®滤波电抗器采用H级铜线,提供高线性度,高过载耐受,低损耗。优质树脂绝缘材料真空浸渍,保证耐压可靠,优秀绝缘性能,低噪音,长寿命。专业的气隙数量和位置的设计,提供相对较低的线圈损耗,整体结构牢固,减少了工作时的噪音产生。过温度保护设计,135℃断开,90℃复通,在电抗器内部温度超过设计温度时提供可靠的自动退出运行功能。

With the rapiddevelopment and progress of electrical appliances, various power electronicdevices are increasingly used in the power system, industry, transportation andhome applications, and the existence of harmonics and the impact on the powersystem become more common and serious. The power capacity in the reactivecompensation product has been gradually not suitable for use in variousoccasions separately, because the parallel resonance generated betweenimpedances of capacitor and power supply system will cause a seriousamplification in harmonic current. With the filter reactor used and with the appropriatereactance rate selected, the combination of capacitor and reactor will absorbup to about 30% to 50% fixed number of harmonic current. This prevents parallelresonance and harmonic current from flowing into the capacity to prevent theamplification of harmonic current, playing a role in purification for theentire power system.

LWKK®filter reactors adopt H-class copper wire, providing high linearity, withstandvoltage under high overload, and low loss. High-quality resin insulationmaterial is vacuum impregnated, to ensure the reliable withstand voltage andexcellent insulation performance, low noise and long life. The professionaldesign of number of position of air gaps provides the relatively low coil loss and solid overall structure, to minimize the noise generated in the operation. Withover-temperature protection design, the power is off at 135℃and on at 90℃, providinga reliable automatic exit function when the internal temperature of the reactorexceeds the design temperature.
