LV shunt power capacitor CMPK

Parameters

Main technical parameters:

1. Rated voltage: 0.23kv, 0.4kv, 0.415kv, 0.45kv, 0.525kv and so on.
2. Rated output: 1-30kvar.
3. Capacitance tolerance: -5% — 10%.
4. Tangent of the loss angle: smaller than 0.1%.
5. Between terminals withstand voltage: 2.15 times rated voltage for 5 seconds.
6. Dielectric level: add voltage between terminal and case: 2times of rated voltage add 2KV or 3KV, choose the higher one, it takes 10s, no spark over or flash.
7. Max permissible over-current: when 1.1 times rated voltage, it can not exceed 8 hours per day; when 1.15 times rated voltage, it can not exceed 30 minutes per day, when 1.2times voltage, can not exceed 5 minutes per day, 1.3times rated voltage, can not exceed 1 minutes per day.
8. Max permissible over-current: 1.3times of rated current, but consider to the voltage, capacitance tolerance and harmonic, the transient current can not exceed 1.43 times of rated current.
9. Discharge feature: it has built-in discharge resistor, discharge 3 minutes, the voltage will down to below 50V after the capacitor cut off the power.
10. According to the IEC60831-2002 standard.

Working conditions

1. Power capacitor should confirm left voltage reduce to rated voltage 10% to input again after the power was cut off, normally it will need 200s almost. So it would choose the power controller which has input and repute lock time function after cut off the power. If choose normally power controller, it must install speediness discharge power equipment. It would not limited which use adopting same electric factor input and chip switch.
2. Altitude level is not more than 2000m.
3. Temperature type: -25/C low temperature, highest temperature is C type (it would not more than 50℃ the average of temperature is not more than 40℃ within 24 hours, one year average of temperature is not more than 30℃), power capacitor will work within good ventilate condition. It would not permit within sealing and installation condition.
