Feature Highlights
Configure the WKG or GKWN type controller to automatically switch capacitors and control the main transformer's tap-changing voltage regulation, maintaining the power factor and system voltage within the set range.
2. Automatically identifies and adapts to various operating modes for dual main transformer substations.
3. With remote automatic selection of switches, various working modes for pressure regulation and compensation can be flexibly chosen.
4. Capable of automatically identifying and displaying the pressure switch position information via BCD code or one-to-one correspondence. Equipped with dual main transformer voltage regulation position synchronization adjustment, anti-slip gear, and light gas alarm interlock for control and protection functions.
5. Displays real-time voltage, current, power factor, reactive power, capacitor switch status, and alarm protection information on the main transformer's low-voltage side.
6. Features harmonic measurement display, capable of real-time measurement and display of the high-order harmonic content of the low-voltage side current.
7. Features high voltage, low voltage, PT open circuit, mechanical failure, and main transformer overcurrent alarm protection functions.
8. Equipped with high-speed data communication interfaces such as RS-485 or RS-232, it coordinates with the integrated automation system of the substation to achieve the "Four Remote" function.
9. Utilizing modular capacitor high-voltage vacuum switches, up to five units can be installed within a single standard switchgear cabinet.
10. Can be flexibly grouped based on total compensation capacity; can be divided into 6 groups with unequal capacities, each group with a capacity of 2000Kvar/5000Kvar, automatically switching in/out based on reactive power.
11. The micro-computer protection device for capacitor bank configuration can achieve two-stage overcurrent and zero-sequence voltage protection functions. It can automatically disconnect and lock when a group fails, without affecting the normal operation of other capacitor groups.
Configure reactors with different ratios to limit inrush current during closing and suppress higher-order harmonics.
