SVC low voltage reactive power compensation device

Performance features:

The SVC low-voltage reactive power compensation device has high compensation accuracy and fast response speed.

High intelligent modularization: high compensation rate, easy expansion, compact structure, design standard, reliable performance and high cost performance.

Unique heat dissipation: module capacitance and reactance are installed on the cross beam overhead, the front mounting panel has a unique natural ventilation passage, and at the same time, it has a forced dispersal

Thermal system to ensure good heat dissipation effect; programmable switching strategy and parameter setting; non-oscillatory switching; anti-voltage fluctuation impact; anti-harmonic interference; high operational reliability, low cost; complete protection, It has protection functions such as overcurrent, quick break, overvoltage, undervoltage and so on.

Working principle:

SVC low-voltage reactive power compensation device uses advanced control algorithm, real-time detection and calculation of the system compensation, control the switching of each compensation branch, to achieve accurate reactive power compensation. A contactor or thyristor contactless switch can be selected according to the characteristics of load variation. The contactor uses a special switch capacitor contactor, and the contactor is equipped with an inrush suppression device. It can effectively reduce the impact of closing inrush current on capacitor banks and reduce the operating overvoltage, while the thyristor contactless switch adopts the advanced technology of constant voltage input and zero crossing removal, which can effectively suppress the on-off surge and improve the performance of the thyristor contactless switch.

The reliability of the system can prolong the service life of the capacitor.
