Self healing low-voltage shunt capacitor BSMJ
QYBSMJ series self-healing low-voltage shunt capacitors are cylindrical in appearance, mainly used to improve the power factor of power frequency power system, improve the quality of power supply and improve the reliability of power consumption.
1. Self healing property: good self healing property, breakdown can quickly and automatically restore the insulation property.
2. Allowable deviation: no more than - 2~+3% of the rated value.
3. Low loss: loss tangent (tg δ) Not more than 0.001 (@ 20 ℃ under rated power frequency voltage)
4. Overvoltage capacity: long-term operation under 1.1 Un.
5. Overcurrent capacity: long-term operation under 1.3 In.
6. Withstand voltage: 2.15 Un is applied from pole to pole, and no breakdown occurs in 2s;
7. Protection mechanism: pressure protection device is set inside.
8. Executive standards: Self healing Low Voltage Shunt Capacitors (GB/T12747-2017) and IEC60831
1. Operating environment - 25~55 ℃; Altitude: ≤ 2000m
2. The installation site shall be free of harmful gas and steam, conductive or explosive dust, and the installation and operation site shall be free of severe mechanical vibration.
3. When the capacitor is put into operation, the special contactor with current limiting device for the capacitor or the contactless switch put into operation when the voltage is zero crossing shall be used. The reactor can also be connected to the capacitor in series to avoid early damage to the capacitor. The inrush current should be limited to 100 times the rated current.
