Core Advantage
- 1The device can operate for a long time under steady-state overvoltage of 1.1 times the rated working voltage;
- 2The device can operate continuously under overcurrent with a root mean square value not exceeding 1.3 times the rated current of the capacitor bank;
- 3The device adopts a vacuum contactor for switching, which can be operated frequently;
- 4Each set of capacitors is equipped with a discharge coil, which can reduce the residual voltage to below 50V within 5 seconds;
- 5Each group of capacitors can be protected by relays or microcomputer protection control units to achieve overcurrent, voltage imbalance, system undervoltage, and overvoltage protection for the capacitor group. When a group of capacitors fails, the capacitors in this group can be cut off without affecting the use of other capacitors;
- 6A single capacitor is protected by a spray type fuse, and each group is equipped with a lightning arrester for overvoltage protection during operation and lightning strikes;
- 7Large screen LCD display controller, real-time display of system voltage, current, and power factor; Equipped with RS232/RS485 standard communication interface and capable of implementing the "four remote" function;
- 8Each group can be configured with reactors to suppress closing inrush current or harmonic amplification.
