MSCLA Low Voltage Reactive Power Automatic Compensation Device

Feature of Product

Resonance verification should be carried out for each set of devices under various working conditions. When selecting a single set of capacity, try to avoid the resonance amplification area, or select an appropriate reactance rate to avoid resonance conditions and ensure that the device can be safe under various working conditions. run.
The device adopts advanced reactive power controller, comprehensive sampling, and has the most advanced programmable switching mode, which can meet the best reactive power compensation effect in various conditions and environments. It has powerful functions and strong anti-interference ability. It can work normally in the power grid environment with large wave distortion, and has alarm functions such as harmonic overruns. It can be equipped with RS232/485 communication interface according to user requirements, and the operation data of the entire device can be uploaded to the monitoring system.
In addition to using a fuse as the overcurrent protection of a single capacitor, it also has an undercurrent alarm and cut off the stepping capacitor, an overvoltage alarm and cut off the stepping capacitor, a temperature 60 ℃ alarm and a 70 ℃ alarm and cut off the stepping capacitor, harmonic waves The perfect protection system, such as alarming when the rate of change exceeds the set value and cutting off the stepping capacitor, can make the device run stably for a long time; in addition to the above protection functions, the device also has the following alarm functions: overcurrent alarm, voltage loss alarm, full input still Lower than COS∮ set value alarm, wrong COS∮ value alarm, alarm when capacitor capacitance is lower than 70% of rated value.
The switching switch can be replaced by a contactor with a thyristor and a composite switch of the contactor, which realizes zero-crossing switching without inrush current, no contact sintering, low energy consumption, and no harmonic injection, ensuring the service life of the switching switch.
For the unbalanced system, phase-split compensation can be realized, which can avoid the drawbacks of over-compensation and under-compensation of a certain phase during the compensation process, and can reduce the harm to the operation of the entire power grid.
