Brief
It is used in an AC power system with rated voltage less than 1.2kV to increase power factor to reduce
reative loss and to improve voltage quality.
Main Features
a. Novel in structure,light in weight
It is produced with Zinc-and-aluminum metallized polypropylene film as the medium so the dimension
and the weight is respectively only the 1/4 and 1/5 of the old.
b. Low loss
Because the actual value is less then 0.12%,energy loss of the capacitor itself is few,the raised temperature
is low,operation life is long and it has outstanding saving energy result.
c. Good self-healing performance
Medium partial impulse caused by the over voltage can healed by itself to operate as before.
d. Safety
It is very reliable because the discharge and insurance devies are installed in it.
e. No omitted oil
Its main immersed agent is the micro-crystal wax,which is solid at normal temperature,its drop-pot
and dissoluble-pot are both above 70 and it won’omit operating,so it won’t pollute the surroundings.
Main Technical Parameter
a Usage environment:surrounding temperaturt is -25 +50 the humidity is less than 85% the
altitude is below 2000m.
b Rated voltage:0.23~1.2kV,AC.
c Rated capacity:1 60kvar.
d Capacity deviation:0 +10%.
e Tangent of the dielectric loss angle:In the power frequency rated voltage,20 is less than 0.2%.
f Withstand voltage between the poles:the rated voltage is 5s if the voltage between the poles is 2.15.
g Maximum permitted over-voltage:it is 1.10 as the rated voltage.
h Permitted over-current:it is 1.30 as the rated current.
i Automatically discharge:It is less than 50V in 3min after power broke down when the Dc is Ã2Un as the before increased by the capacitors.
j It conforms to the standards GB12747-1991 and IEC60831-1996.
