FEATURES:
1. The device can operate stably for a long time under a steady-state overvoltage of 1.1 times the rated working voltage.
2. The device can operate continuously under an overcurrent with a root-mean-square value not exceeding 1.3 times the rated current of the capacitor bank.
3. The device adopts vacuum contactors for switching and can be operated frequently.
4. Each group of capacitors is equipped with a discharge coil, and the residual voltage can be reduced to below 50V within 5 seconds.
5. Each group of capacitors can be protected by relays or microcomputer protection control units to achieve overcurrent, voltage imbalance of the capacitor group, undervoltage and overvoltage protection of the system. When a certain group of capacitors fails, this group of capacitors can be cut off without affecting the use of other capacitors.
6. A single capacitor has a spray-type fuse for protection, and each group is equipped with a lightning arrester for protection against operating overvoltage and lightning strike overvoltage.
7. The large-screen liquid crystal display controller can display the system voltage, current and power factor in real time; it has RS232/RS485 standard communication interfaces and can realize the "four-remote" function.
8. Each group can be configured with reactors to suppress inrush current during closing or suppress harmonic amplification.
