Low Voltage Reactive Power Compensation Capacitor

BSMJ system capacitor is a new generation of power capacitor developed by our company. The terminal structure of this series of capacitors is high-current type, mainly used in large-capacity occasions, and can meet the use of wires up to 35mm2. It adopts a new type of safety and explosion-proof structure, and the terminal adopts a building block combination structure.

1. Loss tangent value: less than 0.0012 at power frequency rated voltage;
2. Capacitance deviation: the difference between the measured value and the rated value of the capacitor does not exceed 0~+10%, and the ratio of the maximum value to the minimum value of the capacitance measured between any two line terminals of the three-phase capacitor is not greater than 1.08;
3. Withstand voltage: pole-to-pole: power frequency 2.15Un, 2s; pole-to-shell: rated voltage 600V and below, applied voltage 3.6kV, 5s;
4. The highest allowable overvoltage: 1.1Un, no more than 8H in every 24H;
5. Maximum allowable overcurrent: 1.3In;
6. Self-discharge characteristics: The capacitor has a discharge device, which can make the residual voltage of the capacitor drop from √2Un to 75V or below within 3 minutes of disconnecting the power supply;
7. Executive standard: IEC60831-2014, GB/T12747-2017
