Product Description

Dynamic Filter Compensator device uses thyristor casting filter to realize the purpose of dynamic reactive power, stablizing voltage and filtering harmonics. The device adopts the zero-pressure differential switching technology of thyristor and specical process design of filter which has the advantages of smooth switching waveform, high harmonic filtering rate, no inrush current and no transient impact, and can continuously switch the filter banks frequently without affecting the life of switches and capacitors. According to the load of the distribution system, the filter banks can be dynamically switched in real time to filter out the harmonic currents in the system, improve the aberration of voltage waveform, dynamically reactive compensation, stabilize the voltage and improve the power factor of users.

Features

1. Adopting contactless switch automatic switching, can switch the filter banks frequently without affecting the life of switches and capacitors. 

2. Rapidly detecting the system conditions and providing fast and real-time compensation according to the amount of reactive power required by the system. 

3. LCD screen display system voltage, power factor, the number of filter groups invested in the system, compensation current and other datas in real time. 

4. According to the customer’s system specially designed, filter effect is obvious, and the power factor after compensation is not less than 0.95. 

5. Fast dynamic response time, the response time no more than 30ms. 

6. No transient impact, no closing inrush current, no arc reignition and no discharge required to re-swtich. 

7. Complete protection, with over-current protection, over-voltage protection, quick break and short circuit protection and two-level temperature protection, etc. High operational reliability. 

8. Little maintenance, low operating costs. 

9. For three-phase balanced load and asymmetric load can realize three-phase or split-phase switching.
