How To Choose High Voltage Filter Compensation Equipment？

           Filter compensation device is mainly suitable for high-voltage (6KV, 10KV, 20KV, 35KV) high-power rectifier equipment and harmonics exceed the standard place, the equipment adopts filter reactor, filter capacitor, discharge coil and non-inductive resistance appropriate combination into LC filter loop (single-tuned filter loop, high-pass filter loop), the loop and harmonic source in parallel. In the actual design, according to the harmonic current composition, size and reactive power demand, through accurate simulation and calculation, the filter device provides a low impedance channel to the harmonics, so that most of the harmonic current in the system flows into this low impedance channel.
           According to the actual situation of the load, it can be divided into 3 phase 6 pulse rectification, 6 phase 12 pulse, 12 phase 24 pulse. A single harmonic loop and high-pass filter loop can be used to form a filter system, which can filter the harmonic components in the system and meet the requirements of fundamental wave compensation output. The single-tuned filter circuit can filter out the characteristic harmonics of the power grid, which can absorb most of the system and reduce the distortion of the system voltage. For the fundamental frequency (50Hz), the filter device can provide reactive power to the system to improve the power factor and achieve the effect of reactive power compensation. The high-pass filter loop has a wide frequency range above a certain frequency, which is used to absorb several higher-order harmonics of higher frequencies to achieve filtering effect, and at the same time compensate reactive power to reduce voltage distortion.Filter compensation device is mainly suitable for high-voltage (6KV, 10KV, 20KV, 35KV) high-power rectifier equipment and harmonics exceed the standard place, the equipment adopts filter reactor, filter capacitor, discharge coil and non-inductive resistance appropriate combination into LC filter loop (single-tuned filter loop, high-pass filter loop), the loop and harmonic source in parallel.
