KLD-BMS2000 Series High Performance Harmonic Protector

PRODUCT OVERVIEW

Ideal power supply should be a sinusoidal waveform with a single constant frequency and specified amplitude. When a sinusoidal voltage is applied to a non-linear load, the current will be distorted into a non-sinusoidal waveform, which leads to a voltage drop in the grid impedance, making the voltage waveform turn to be non-sinusoidal as well. Applying Fourier series decomposition to non-sinusoidal waveforms, in which the component with the same frequency as the industrial frequency is called the fundamental wave, and the component with a frequency greater than the industrial frequency is called the harmonic wave.

KLD-BMS2000 series high-performance harmonic protector eliminates harmonics at the power side through digital logics and detects the current waveform generated by non-linear loads in the power grid in real time. It decomposes and reverses the harmonic wave, and then injects the reversed current into the power grid by triggering IGBT inverter to filter out the harmonics. It is mainly applied to the control of harmonics at the power side to protect the important power equipment of customers.

MODULAR DESIGN

KLD-BMS series high-performance harmonic protector adopts modular design with intelligent duct design, featuring lower loss and more convenient application.

It has complex model structure, wall-mounted and rack-mounted models are all designed in modules. Its compact space design and accurate capacity control can fully meet the needs of different customers, and applicable to a wide range of fields, making it very convenient in the transportation process, capacity increase and maintenance at the later stage. Also, the modular design is easier to be integrated into the power distribution cabinet.
