Wholesale Price Transformer - GGJ Low Voltage Reactive Compensation Equipment 0.4kV Switchgear Type Metal Electrical Control Load Center – Pengbian

Overview

As this device can effectively improve the power factor of the electrical load, reduce the line loss, and improve the actual load capacity of the transformer, it has a significant energy saving effect. At the same time, the use of a specific reactor in the system can also be effective Prevent harmonic amplification and effectively absorb most of the harmonic currents, so that the harmonic voltage total distortion rate limit and the harmonic current content limit of each sub-harmonic current meet the national standards, and achieve the purpose of harmonic control. And if you use an ordinary contactor to cast Cutting the capacitor bank will bring about large inrush current, slow compensation time, high maintenance cost and short service life. Therefore, we recommend that users give priority to dynamic reactive power compensation in the following situations Devices such as: low-voltage power grids in industrial and mining enterprises’ substations, production workshops, and civil buildings are particularly suitable for transmission and distribution systems with frequent changes in load and unstable reactive power.

This product complies with: G8/T15576-2008 “Low-voltage complete set of reactive power compensation equipment”, IEC60439 “Low-voltage complete set of switchgear and control equipment” and other standards.
