Compensation filter cabinet
The function of the low-voltage automatic reactive power compensation and harmonic elimination device is to improve the power factor of the power system, avoid power adjustment fees, reduce the loss of power supply transformers and transmission lines, improve power supply efficiency, suppress harmonics, improve the power supply environment, and improve the quality of the power grid.
1. Equipped with reactive power (reactive current) controller, which can be controlled manually/automatically;
2. Multiple switching methods such as circular switching, coding switching, sequential switching and so on;
3. Real-time monitoring of the system's voltage, current, power factor, harmonics, compensation status and other parameters;
4. The switching delay can be adjusted from 0 to 120s, and the fastest can reach 1s under special requirements;
5. Complete protection measures such as overvoltage, undervoltage, overcurrent, short circuit, and misoperation;
6. Avoid capacitor resonance, shunt 20%~30% characteristic sub-harmonic current;
7. Low investment cost, mature technology, stable performance, suitable for most low-voltage compensation.
Technical parameters 1. Maximum capacity of a single cabinet: 540kvar;
2. Maximum control branch: 12 roads;
3. System voltage: 400V;
4. Reactance rate: 6%, 7%, 12%, 14%;
Applicable classic load: annealing furnace, intermediate frequency furnace, high frequency furnace, AC and DC transmission, food processing, ceramic processing, electroplating, electrolysis, subway station, residential area, papermaking, textile, rubber and other industries.
