低压无功智能补偿装置

Low-voltage reactive power compensation device

概述 /Overview

由于本装置能有效改善用电负荷的功率因数，降低线损，提高变压器的实际负载能力，具有显著的节能效果，同时在系统中采用特定的电抗器，还可以有
效防止谐波放大、有效吸收大部分谐波电流，使谐电压总畸率限值及各次谐波电流含量限值符合国家标准，达到谐波治理的目的。而如果使用普通的接触
器投切电 容器组，带来的将会是大的浪涌电流，慢的补偿时间、高的维护费用和短的使用寿命，因此，我们建议用户在以下场合，能优先考虑使用动态无功
补偿装置如：工矿企业的变电所、生产车间及民用建筑等的低压电网中，特别适合负荷经常变化，无功功率不稳定的输配电系统。
本产品符合：G8/T15576-2008《低压成套无功功率补偿设备》、IEC60439《低压成套开关设备和控制设备》等标准。
Since the device can effectively improve the power factor of the power load, reduce the line loss, improve the actual load capacity of the
transformer, and has significant energy saving effect, and adopting a specific reactor in the system, the harmonic amplification and effective
absorption can be effectively prevented. Most of the harmonic currents make the harmonic voltage total distortion rate limit and the harmonic
current content limit meet the national standards and achieve the purpose of harmonic control. However, if a common contactor is used to
switch capacitor banks, it will bring about large inrush current, slow compensation time, high maintenance cost and short service life. Therefore,
we recommend that users give priority to the following occasions. Consider the use of dynamic reactive power compensation devices such as
substation, industrial workshops, and low-voltage power grids for civil and industrial enterprises. It is especially suitable for transmission and
distribution systems with frequent load changes and unstable reactive power.
This product complies with: G8/T15576-2008 "Low-voltage complete set of reactive power compensation equipment", IEC60439 "Low-voltage
switchgear and control equipment" and other standards.
