Product introduction
GRO-FK composite switch is a new generation of low voltage reactive power compensation of capacitor switching on-off switch device, perform component is a kind of intelligent energy - saving environmental protection is our SCR and ac contactor in th e low voltage reactive p ower compensation application aspects of congenital deficiencies carefully developed by the latest scientific and technological achievements.
GRO-FK series low-pressure compound switch basic working principle: Keep SCR and magnetic relay in parallel,controlled by the internal control,at the ins tant of the i nput and removal shall be borne by the thyristor zero cutting , ie . voltage zero moment , current zero moment res ection, SCR do not produce heat conduction time is short, afer magnetic relay through to run.
It has TSC silicon controlled switch is zero for the advantages of no flow, and has the strengths of ac contactor operation without power, also to avoid the SCR running fever and spark the defects of contactor. Especially because magnetic relay on and off and disconnect the instantaneous flow and spark, the electrical life so it is much higher than design life, and its mechanical life as much as one million times.
| Technical parameters: | |
|---|---|
| Rated voltage: | Common compensation: AC 380V土20% 50Hz Saparate compensation: AC 220V土20% 50Hz |
| Control capacity: | Common compensation: ≤30kvar Separate compensation: ≤30kvar |
