SLVC low voltage intelligent reactive power compensation device

上市日期: 2018-09-28

SLVC series dynamic filter compensation device is mainly used for harmonic suppression and reactive power compensation for low-voltage systems with low power factor and harmonic pollution. The device can choose different structure types and switching switches to automatically track the load changes according to the load characteristics and changes, and respond in real time, which can keep the system power factor in the best state at the same time while filtering harmonics. It is suitable for various working conditions, especially for sudden load, such as rapid compensation of reactive power of sudden load such as electric welding machine, injection molding machine, rolling mill, air compressor and so on. The device is composed of a controller, thyristor (or contactor), capacitor, reactor, etc .; the core device of the controller uses DSP, which quickly analyzes and calculates the data sampling of the power grid system, and generates a switch for the capacitor bank Control instructions, switch on and off the thyristor (or contactor) in time until the system reaches the target power factor. The capacitors and reactors are reasonably configured according to the harmonics of the system, and can be composed of three different structural forms of pure reactive power compensation, partial tuning, and tuning. They are suitable for the system without harmonics, harmonics, but low content, harmonic Three different occasions with large content.
