Publication time：2024-03-22 writer： views（1909）

The HYDR low-voltage passive filtering compensation set produced by Henan Hengyu Electric Group is specially designed for the actual situation of the power grid. It adopts power electronics technology and intelligent control technology, which solves the problem of automatic switching of parallel capacitors for reactive power compensation under filtering conditions. On the other hand, it can filter out harmonics according to user actual requirements, clean the power grid environment, reduce losses, and eliminate harmonic hazards; And provide capacitive reactive power to the system to improve power factor. Can be used in power distribution systems in industries such as electricity, metallurgy, petrochemicals, industrial and mining enterprises, and machinery.
Introduction to Structure
1. Voltage zero crossing switching compensation device, which can frequently and quickly switch capacitors;
2. Fast response speed, fast tracking of reactive power changes in system loads, real-time dynamic or static response switching;
3. Adopting automatic/manual switching devices for capacitors, which can be operated frequently to improve compensation fineness;
4. The top of the cabinet is equipped with a cooling fan, which is controlled by a temperature control switch to adjust the temperature inside the cabinet in a timely manner;
5. Protection function: With short-circuit, overload, overvoltage, undervoltage, and short-circuit protection, easy to set.
