Code and Implication of the Low-Voltage Shunt Power Capacitor
Introduction to the Low-Voltage Shunt Power Capacitor
ZHIMING brand of Power reactive compensate technology develop, for three phase unbalance load, you can adapt three phase input cut capacitor way, sub compensate reactive power, so it can make the compensate accuracy is high, saving electric impression is best, so our company develop sub compensate shunt power capacitor, his cover setting neuter lead to terminal block, it can convenient make power capacitor sub cut and input. This product instruction characteristic mainly about technology data.
Standard: IEC 60831-2014
Structure Features of the Low-Voltage Shunt Power Capacitor
- Three single-phase capacitors should be connected like Y-, with the neutral point introduced out (End N), thus three single-phase capacitors are composed. The AN, BN, and CN are independent units during operation.
- Each independent unit is connected with a discharge resistance.
- Any damage to the independent unit is connected with over overvoltage buffer to shunt off.
- Note: three single-phase capacitors with an independent unit are also suitable for the split-phase compensation. The three capacitors are small and are deeply appreciated by the users.
Main Technical Data Working Conditions of the Low-Voltage Shunt Power Capacitor
Power capacitor should confirm the left voltage reduced rated voltage by 10% to the input again after the power was cut off, normally it will need 200s almost. So it would choose the power controller which has an input and a repu lock time function after cutting off the power. If you choose a normal power controller, you must install speediness discharge power equipment, which would not be limited to which use of adopting the same electric factor input and chip switch.
Altitude level: No more than 2000m.
Temperature type: -25/C low temperature, the highest temperature is C type(it will not be more than 50℃the average temperature is not more than 40℃within 24 hours, the yearly average of temperature is not more than 30℃. A power capacitor will work within well-ventilated conditions. It would not permit within sealing and installation conditions.
Main Technical Data of the Low Voltage Shunt Power Capacitor
- Rated voltage: 230VAC, 250VAC, 400VAC, 415VAC, 450VAC, 525VAC. Other special voltage, please note it.
- Rated capacity: 1~100kvar
- Rated frequency: 50Hz or 60Hz
- Capacity tolerance: -5~+10%
- Loss Angle Tangent(Power Frequency Rated Voltage): tgδ≤0.01 at 20°C
- Anti-voltage: between two poles 2.15 times rated voltage is 10s, between two poles 3kV, please choose the highest value 10s, there is no permissibility puncture and Flash over.
- Max permit over voltage: 1.1times rated voltage, the high permit over voltage is not more than 8 hours within 24 hours; 1.15 times rated voltage, it is not more than 30 minutes within 24 hours; 1.2 times rated voltage, it is not more than 5 minutes; 1.3 times rated voltage, it is not more than 1 minute.
- Max permit over current： it is permitted that the overcurrent is not more than 1.3 times the rated current. Interim overcurrent, it should consider overvoltage, capacity positive tolerance, and harmonic effect. Interim over current is not more than 1.43 times rated current.
- Discharge property: the left voltage will reduce from √2 Un to below 50V within 3 minutes when the power is cut off.
