FDK Series Intelligent Dynamic Compound Switch
FDK dynamic Complex switch is a new generation of fast response of the exchange switch, using micro-computer control, thyristor switched at zero voltage circuit, the response time machine is less than 20ms, zero current hours off circuit, connected to, and no impact on the process of breaking surge current. Thyristor turn 20ms to maintain relay contacts within the switch to magnetic bearing, no pressure drop, no wear and tear. Do not need to install radiator. Especially suitable for dynamic switching of compensation capacitors.
2.Conditions of Use
1. Not more than 2500 meters above sea level.
2. Ambient temperature-25`C~+70`C.
3. Air humidity at 40`C does not exceed 90% of the.
4. The surrounding environment without corrosive gas, non conductive dust, there is no flammable and explosive media.
5. Voltage fluctuation range of not more than rated voltage =/-20%
3.Conde and implication
1.Switches connected using a zero-voltage technology, nonrushcurrent during condition.
2.Zero-current breaking switch technology, without breaking continueact when the arc.
3.Switch turn-on when the use of contact load, no less.
4.Had when the OV voltage or under-voltage lights, blocking the output.
5.Power shortage phase or when the load phase lack OL lights, blocking the output.
5. Application Note
1. Power System Voltage total harmonic distortion THDu more than 5%, the need to install according to the value of harmonic content of an appropriate a mount of filter reactor LB. Otherwise the compound switch easily damaged.
2. Application FDKF phase composite switch, Y received single phase capacitor midpoint Nlines to be raliable connection, or com pound switch easily damaged.
3. Compound switch due to the presence Latching Relay conversion process. Does not apply to, the working hours of less than 1 secre-taryond and the load to compensate for frequent movement, such as spot welding.
4. Compound using a zero-voltage switch connected to technology, we must take a load before they can move, only join discharge lights (according to principles of icon) to allow movement test, the switch does not turn when the signal light micro-light is normal.
5. In the power phase and then there is no shortage of the state of the load, OL lights may be a phase switch is not breaking, the need to re power transmission time, i minute if the OL after the lights are still bright, it would take to replace this switch.
6. There are special requirements or changes in application methods.
