Self-healing type low voltage shunt capacitor (HZK-F)
Main Feature:
Compacted and light: Its volume and weight are only 1/4 and 1/5 of the old product because of using a new dielectic-metallized polypropylene film.
Self-healing type low voltage shunt capacitor (HZK-F)
Low loss: The real figure is lower than 0.10%, so the loss of the capacitor itself is extremely low, the heat gives out is little and the rise
of temperature is low, so its service life is very long and it can save energy at the same time.
Excellent self-healing ability: Damage of part of the dielectric caused by overvoltage can be self-healed quickly and return to normal state. So the reliability is much higher.
Safety: Inwardly equipped self-discharge resistor and safe equipment. The self discharge resistor can automatically discharge the electric energy the capacitor carries. If there is anything fault with the capacitor, the safety equipment will cut off power in time, thus avoid further from happening. Insure much safer to use this kind of capacitor.
No oil leakage: The capacitor uses advanced semi-soild impregnant whose drip melting point it above 70º C. There will be no loss of oil during the course of using it, and thus protect the surroundings from being polluted. The capacitor dosen't have to run the risk of invalidation caused by oil leakage.
Technical Parameters:
Sevice conditions: Ambient temperature-25º C~+60º C, humidity≤ 85%RH, and altitude lower than 2000m.
Rated voltage: 400Vac, 415Vac, 440Vac, 450Vac, 480Vac, 525Vac.
Rated output: 1-50kvar.
Capacitance tolerance: -5~+10%
Tangent of the loss angle: With the power frequency rated voltage for 10 seconds, between terminals and container 3kvar for 10 seconds. Withstand voltage: Between terminals 2.15 times of rated voltage for 10 seconds, between terminals and container 3kvar for 10 seconds. Max permissible over-voltage: 110% of rated voltage.
Max permissible over-current: 130% o2f Rated current.
Self sustained discharge ability: Give √ Un DC voltage to capacitor, the residual voltage reduced to 75V or lower within 3 minutes after power off
Applicable standard: GB 12747-2004/IEC60831-2002
