Polypropylene CMKP Cylinder Capacitor Low Voltage Parts
Cylinder type CMKP Low Voltage Power Capacitor
2. Use microcrystalline wax and healthy dielectric oil as the impregnant.
3. It has a built-in pressure separation device and discharge resistor.
4. Use dielectric metalized polypropylene film as medium.
5. In the top of the capacitor is electric shock-resistant protection connecting the terminal.
6. In the bottom is M12 or M16 earth ground screw.
Product Introduction
Working Condition
1. Alitude: lower than 2000m
2. Ambient temperature -25℃ - 50℃
3. Humidity: smaller than 90%
4. After the power cut off, reputing when make sure the remain voltage is smaller than 10% of the rated voltage, usually this thime is 200s, so the controller you use should has the function of time delay for reputing after cut off.
Parameter
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.
