Low-voltage Dynamic Reactive Power Compensation Device
Short Description:
In systems with significant load variations, the amount of reactive power compensation required also varies, and traditional fixed reactive power compensation devices can no longer meet the compensation needs of such systems. The Z-series SC low-voltage dynamic reactive power compensation device is specifically designed for these types of systems. This device can automatically track load changes and provide real-time compensation, keeping the system's power factor at an optimal level. At the same time, it uses a modular series design, allowing for flexible combinations. It is easy to assemble and maintain, can be expanded as needed, and offers a very high cost-performance ratio.
Product details
Product Overview
In the system with large load variation, the amount of compensation required for reactive power compensation is also a variable, and the traditional fixed reactive power compensation device can no longer meet the compensation requirements of such systems. The SC low-voltage dynamic reactive power compensation device under Z is specially designed for this type of system, which can automatically track and compensate in real time according to the load change, so that the power factor of the system is always kept at the best point, and the modular series can be freely combined, easy to assemble and maintain and can be expanded at will, and the cost performance is very high.
Applications:
KRTBBD low-voltage dynamic reactive power compensation device is suitable for working conditions with rapid load changes in metallurgy, machinery, mining, building materials, petroleum, chemical, municipal and other industries.
Key features:
compensate for the reactive power required by the system and improve the power factor;
increase the utilization rate of transformers and transmission lines, and reduce equipment investment costs;
reactive power compensation device reduces the reactive power loss of transformers and transmission lines;
increase system voltage and stabilize power supply quality;
A series reactor with a reactance of 1%-13% is optional, which can limit the closing inrush current and suppress a specific number of harmonics.
Improve the service life of equipment in your system, especially for capacitive loads.
How it works:
The control algorithm adopted by the KRTBBD low-voltage dynamic reactive power compensation device detects and calculates the compensation amount required by the system in real time, controls the switching of each compensation branch, and realizes accurate reactive power compensation. The switch switch can use a contactor or an intergence tube contactless switch according to the load change characteristics, in which the contactor adopts a special switch capacitor contactor, and the contactor is equipped with an inrush current suppression device, which can effectively reduce the impact of closing inrush current on the capacitor bank and reduce the operating overvoltage. The thyristor contactless switch adopts the technology of isovoltage input and zero cutting, which can effectively suppress the switching surge, improve system reliability and extend the service life of the capacitor.
