プロジェクトの背景:
サイトの主な治療オブジェクトは4157kvaです, 10/0.6KVトランス, 主な負荷はユニットです 6 およびユニット 14 melting machines used to produce crucibles. The passive capacitor compensation cabinet installed on site was powered on for the first time. Less than three minutes after it was put into operation, one of the capacitor circuit fuses burned out. After user testing, it was found that the harmonics on site were very serious, which made the passive compensation unable to be put into operation.
高調波ソリューション:
To control the harmonics, active filters with a total capacity of 550A were installed.
機器の選択: アクティブパワーフィルター (APF)
機器モデル: CoEpo APF/550A-0.4-d
設置容量:550a
インストール方法: Rack Mounted
効果:
The 600V side distribution system of the transformer had serious voltage and current distortion before active filter compensation. After the active filter was turned on, the system voltage distortion rate was reduced from 31.4% に 14.5%, and the system current distortion rate was reduced from 23.7% に 9.6%. The system’s current and voltage waveforms were improved from the previous severely distorted waveforms to close to sine waveforms, and the 5th harmonic current in the system was improved from 508.5A to 51.9A, with a compensation rate of 89.7%. さらに, after the active equipment compensated for the other harmonic currents of 2 に 13 時代, the current content of each order decreased, and the treatment effect was significant, achieving the expected effect.
