低压无源电力滤波装置试验探讨

摘要

用无源电力滤波装置解决电力电网谐波电流超限和功率因数低的问题,是一种经济、有效的方法。鉴于目前低压电力滤波装置型式试验没有可参照的国家或行业产品标准,本文提出了低压无源电力滤波装置的试验项目及方法,重点阐述了滤波效果试验和并联谐振试验的检验方法。按本文阐述的试验项目及方法检验合格的产品,现场运行稳定可靠,滤波效果良好。%It is a economical and effective mothed using low-voltage passive power filter to solve the problem of harmonic currents transfinite and low power factor in power grid.At present there is no according national institute of standards or industry standards for low-voltage passive power filter’s type test,so this paper proposes low-voltage passive power filter’s test items and methods,focusing on the test methods of filtering effect and parallel resonant.The product passed the test runs well in working place.
