DYNAMIC PFC COMPONENTS
Fast Track and CompensationFor Occasions with Frequently Changing Load
BKT series dynamic compensation components consist of low-voltage capacitors, filter reactors and thyristor switching switches, and used for occasions with fast changing load.The scheme makes the system voltage become stable and safe, and damage, and noise of electrical equipment can be avoided.
Stable and Reliable
Adopting low-voltage capacitor of higher rated voltage: 7% BKS series compensation filter component adopts 480v capacitor, 14% BKS series compensation filter components adopt 525V capacitor.
Solution Characteristics
- Fast response speed, response time is less than 20ms.
- Reasonable configuration, can achieve reactive power compensation and partial harmonic filtering.
- 7% BKS series compensation filter component adopts 480v capacitor, 14% BKS series compensation filter components adopt 525V capacitor, more stably and reliably.
- Using class H insulation, filter reactor of pure copper winding, low power consumption, high reliability.
- Great autonomy in layout of cabinet internal, with flexible selection.
Application Areas
The dynamic compensation component is suitable for occasions with fast and frequently changing load, such as welding equipment.
- BKT series compensation component with reactance rate of 7%, tuning frequency of 189Hz can effectively suppress the 5th or above harmonic pollution.
- BKT series compensation component with reactance rate of 14%, tuning frequency of 134Hz can effectively suppress the 3th or above harmonic pollution.
